Immunotherapien.

Damit möchte ich einen Überblick gewinnen und schaffen über die derzeitige Entwicklung auf  dem Gebiet der Antikörpertherapien + Immunotherapien, natürlich vorwiegend soweit börsennotierte  Unternehmen involviert sind. Da es sich um einen neueren Threapieansatz handelt - derzeit sind laut 'Nature' 18 Medikamente zugelassen, die auf
Antikörpern basieren, wird die weitere kommerzielle Nutzung des Therapieansatzes und damit auch die Börsenkurse der betroffenen Unternehmen von weiteren Zulassungserfolgen abhängen.
Dieser Trend  soll hier beobachtet und ggf. kommentiert werden. Ergänzungen willkommen.

New monoclonal antibody therapies offer significant survival advantage for breast cancer patients

Paris, France, Monday 31 October 2005 - Results from the first and only interim analysis of an important trial assessing the potential of Herceptin (trastuzumab) to improve disease-free survival (DFS) in HER-2 positive breast cancer patients after adjuvant chemotherapy, have shown that Herceptin affords a significant survival advantage. These new findings were released at the 13th European Cancer Conference (ECCO) on the recommendation of the Independent Data Monitoring Committee.

The study in question, an international, multicentre, randomised, 3-arm trial is being conducted by the Breast International Group (BIG) in collaboration with the pharmaceutical company Roche AG, manufacturers of Herceptin. In total, 5,090 early breast cancer patients have been enrolled into this trial by the 478 participating institutions from Europe, Canada, South Africa, Israel, the Asia Pacific Region, Japan and Latin America. All women accrued had HER-2 positive breast cancer (either node negative or positive) and had completed at least four cycles of an acceptable (neo) adjuvant chemotherapy regimen. For women with hormone receptor positive disease, adjuvant endocrine therapy (most commonly tamoxifen) followed chemotherapy. The average age of study participants is 49 years.

The aim of this trial is to compare the effect of 1 year of Herceptin infusions, given every 3 weeks, with one year of simple observation, on survival – primarily DFS but also overall survival (OS), relapse-free survival (RFS) and distant disease free survival (DDFS), as well as comparable assessment of overall and cardiac safety. The study also consists of a 2-year arm – where 2 years of 3-weekly Herceptin is being compared with observation.

Results from the 1-year arm of the study, showcased at ECCO 13, show that Herceptin is associated with a significant improvement in DFS in this group of patients. The difference in Herceptin treated women was 85.8% compared to 77.4% of women on observation alone. Patients receiving Herceptin therapy for 1 year also showed significant improvements in other survival measures – including RFS and DDFS. OS was also better in the Herceptin group versus observation, although the difference was not significant. In terms of safety, Herceptin-treated women experienced a higher incidence of cardiac side effects, which occurred in 0.5% of patients. In contrast, no observational patient experienced an adverse cardiac event.

These positive results are further supported by preliminary survival data from the 2-year Herceptin arm which also demonstrate a highly significant improvement in DFS compared with observation (p<0.0001). This important trial is continuing, gathering further data to assess and compare 2 years versus 1 year of Herceptin treatment, as well as carefully monitoring potential late-stage effects.

Professor Michael Untch, the study's Principle Investigator, from the Frauenklinik der LMU München Klinikum Grosshadern, Germany remarked: "These notable early findings show that Herceptin can provide significant improvements in survival for women with early HER-2 positive breast cancer who have completed initial chemotherapy cycles. By reducing the incidence of recurrences and metastasis by 50 % it means that patients have a significant gain in their chance to survive and a tremendous increase of their life quality. "

Another new monoclonal antibody, bevacizumab has recently completed Phase III clinical trials for the treatment of locally advanced or metastatic breast cancer. Bevacizumab is a monoclonal antibody to vascular endothelial growth factor (VEGF) and acts to inhibit tumour angiogenesis (process of diverting nutrients to the tumour).

The randomised Phase III trial was coordinated by the Eastern Cooperative Oncology Group to compare the efficacy and safety of paclitaxel with or without bevacizumab as first line therapy in patients with locally advanced or metastatic breast cancer. 722 patients were recruited between December 2001 and May 2004 and were divided into two groups receiving either paclitaxel alone or the combination of paclitaxel and bevacizumab. The primary endpoint was progression-free survival (PFS).

The results were positive and indicated that the combination of paclitaxel and bevacizumab improved overall survival of patients than receiving paclitaxel alone (no final data available yet). Importantly the progression-free survival was improved with combination therapy, 10.97 months vs 6.11 months for paclitaxel alone. In addition, the investigators noted that combination therapy did not cause significant toxicity effects.

Speaking at ECCO 13, Dr Kathy Miller from the Indiana University Cancer Centre, USA, commented, "This is the first study to confirm the benefit of anti-angiogenic therapy in patients with breast cancer. Importantly, the improvements in response rate and progression-free survival were obtained with minimal increase in side effects. Given the benefit of bevacizumab in patients with metastatic disease, we look forward to initiating trials in the adjuvant setting."

About Breast cancer
Breast cancer is a malignant tumour that usually begins in the milk ducts (ductal carcinoma) or lobules or milk producing tissue (lobular carcinoma) of the breast. Either type if diagnosed early enough, may be called 'in situ' which means the cancer has not spread or invasive if it has. Rarer breast cancers affect other types of breast tissue.

Breast cancer is the most commonly diagnosed cancer in women, nearly 1 in 3 of all cancers in women occur in the breast.1 80% of breast cancers appear in post-menopausal women. Although rarer, some men can suffer from breast cancer.

Associated risks of breast cancer can be attributed to genetics, early onset of menstruation, no pregnancies or first pregnancy after the age of thirty, previous breast disorders, alcohol, smoking and diet.2

Treatment depends on the staging of the disease, classified from I to IV (higher the number, the more advanced the cancer). Surgery and radiotherapy is usually first line treatment, however hormone or chemotherapy treatment can be given first to shrink the tumours. The majority of breast cancers are hormone responsive and can be treated with oestrogen blockers such as tamoxifen or the newer aromatose inhibitors which are normally administered after surgery to prevent the cancer returning.

In non-hormone responsive breast cancers, which includes those with a genetic predisposition to breast cancer and who are carrying the HER2 gene, the new drug Herceptin offers hope. It is successful in blocking the growth-promoting protein found on the surface of most breast cancers thereby preventing the spread of the cancer.3 Recently other types of biological therapies similar to Herceptin are starting to show promise in the treatment of advanced breast cancers.

Patientenregistrierung für klinische Forschungsstudie zur Wirkung von REOPRO(R) (abciximab) bei akutem ischämischen Schlaganfall vorläufig ausgesetzt
Mittwoch 5. Oktober 2005, 01:06 Uhr
 


HORSHAM, Pennsylvania und INDIANAPOLIS, October 5 /PRNewswire/ -- Centocor, Inc. und Eli Lilly and Company gaben heute bekannt, dass die
Registrierung für die AbESTT II-Studie (Abciximab in Emergent Stroke
Treatment Trial-II) (AbESTT-II), die Studie der Phase III für REOPRO(R)
(abciximab) zur Behandlung eines akuten ischämischen Schlaganfalls, vorläufig
ausgesetzt wurde. Der unabhängige Ausschuss für die Studie SEMC (Safety and
Efficacy Monitoring Committee; Ausschuss zur Überwachung von Sicherheit und
Wirksamkeit) stellte anhand der bisher gesammelten Studiendaten
ANZEIGE
 
Sicherheitsbedenken fest und bewertet gegenwärtig das gesamte
Nutzen-Risiko-Profil von REOPRO für Patienten mit einem akuten ischämischen
Schlaganfall, bevor er endgültig entscheidet, ob die Studienregistrierung
fortgesetzt werden soll. Die zur Zeit für die Studie registrierten Patienten
erhalten das Medikament nicht weiter, die Daten für diese Patienten werden
überprüft, bevor der SEMC seine Empfehlung abgibt, wie mit der Studie
AbESTT-II weiter zu verfahren ist.


"Unsere erste Priorität ist die Sicherheit. Deshalb stoppen wir die
Registrierung, damit der SEMC die Daten sorgfältig auswerten und festlegen
kann, ob das Nutzen-Risiko-Profil für REOPRO zur Behandlung des akuten


ischämischen Schlaganfall zulässt, die Registrierung zur Studie
wiederaufzunehmen", sagte Dr. Jerome A. Boscia, Senior Vice President für
Klinische F&E bei Centocor, Inc. "Es ist jedoch wichtig anzumerken, dass
REOPRO für seine genehmigten Einsatzbereiche bei Patienten, die sich
Eingriffen am Herzen, wie einer Angioplastie oder Stent-Implantation,
unterziehen, über ein etabliertes positives Nutzen-Risiko-Profil verfügt."


REOPRO gilt gegenwärtig als Mittel zur Unterstützung einer perkutanen
Koronarintervention (PCI) zur Verhinderung von ischämischen
Herzkomplikationen bei Patienten, die sich einer PCI unterziehen, sowie bei
Patienten mit instabiler Angina, die auf herkömmliche medikamentöse Therapie
nicht ansprechen, wenn die perkutane Koronarintervention innerhalb von 24
Stunden geplant ist. Die Unternehmen unterstreichen noch einmal eindeutig,
dass sie keinerlei neue Daten kennen, die das positive Produktprofil für
REOPRO unter genehmigten Indikationen ändern, also unter Indikationen, die
durch über 14 randomisierte klinische Studien und durch ein ganzes Jahrzehnt
klinischer Erfahrungen unterstützt werden. Die gegenwärtige Studie AbESTT-II
bewertet die Sicherheit und Wirksamkeit von REOPRO bei Patienten mit akutem
ischämischen Schlaganfall.

 

Über AbESTT-II


AbESTT-II ist eine multinationale, multizentrische, randomisierte,
doppeltblinde, placebokontrollierte Studie der Phase 3, die die
Sicherheit und Wirksamkeit von REOPRO zur Verbesserung der neurologischen
Funktion und zur Minimierung der Behinderung bei Patienten bewertet, die
einen akuten ischämischen Schlaganfall erlitten haben. Vorläufige Ergebnisse
aus anderen Studien legen nahe, dass sich REOPRO für die
Schlaganfallbehandlung über das Zeitfenster von drei Stunden hinaus als
nützlich erweisen könnte, innerhalb dessen die einzige, zur Zeit genehmigte
Therapie eingesetzt wird, um bei Patienten mit ischämischen Schlaganfall
Blutgerinnsel aufzulösen. Die meisten Schlaganfallpatienten kommen erst
später als drei Stunden nach Einsetzen der Symptome in der Notaufnahme an.
Die Studie bewertet zwei Populationen: innerhalb von 4,5 Stunden
randomisierte Patienten mit einer geplanten Behandlung innerhalb von fünf
Stunden nach Beginn des Schlaganfalls (primäre Analysepopulation, n=1200) und
eine begleitende Population von Patienten, die 4,5 bis 5,5 Stunden nach dem
beginnenden Schlaganfall randomisiert werden und bei denen die geplante
Behandlung innerhalb von sechs Stunden begonnen wird oder die mit
Schlaganfallsymptomen aufwachen und innerhalb von 2,5 Stunden nach dem
Erwachen randomisiert werden (n=600). Im Mai 2005 wurde die Behandlung jenes
kleinen Segmentes an Patienten, die nach einem erlittenen Schlaganfall
aufgewacht sind, aufgrund eines erhöhten intrakraniellen Blutungsrisikos in
dieser Population eingestellt. Zu diesem Zeitpunkt empfahl der SEMC die
Fortführung der Registrierung, wobei die verbleibenden Gruppen in der Studie
bewertet werden sollten.


An dieser weltweiten klinischen Studie 'AbESTT-II', die 2003 begann,
nehmen ca. 150 Institutionen teilen. Ziel waren 1800 registrierte Teilnehmer.

 

Über den akuten ischämischen Schlaganfall


Ein akuter ischämischer Schlaganfall tritt ein, wenn im Gehirn ein
Blutgefäss blockiert wird. Diese Blockade verhindert, dass Sauerstoff und
Nährstoffe im Blut zu einem bestimmten Gehirnteil gelangen, wodurch dieses
abstirbt. Ungefähr 85 % aller Schlaganfälle gelten als ischämisch, werden
also durch ein Blutgerinnsel oder eine Ablagerung verursacht, das bzw. die im
Gehirn ein Blutgefäss blockiert. In den Vereinigten Staaten sind
Schlaganfälle die dritthäufigste Todesursache und führen jährlich zu über
150.000 Todesfällen.

 

Wichtige Sicherheitsinformationen


REOPRO kann potenziell - besonders bei anwesenden Antikoagulationsmitteln
, wie Heparin, oder anderer Gerinnungshemmer oder Thrombolytika - das Risiko
von Blutungen erhöhen. Das Risiko einer grösseren Blutung infolge einer
REOPRO-Therapie ist bei Patienten erhöht, die Thrombolytika einnehmen, und
sollte gegen die erwarteten Nutzeffekte abgewogen werden.


Zu den Richtlinien zur Verringerung von Blutungen zählen u. a.: der
Einsatz eines gering dosierten, an das Gewicht angepassten Heparinkur, die
Einstellung der Heparin-Einnahme bei Abschluss der Prozedur mit Entfernung
der Arterienscheide innerhalb von sechs Stunden, sorgfältige Beobachtung und
Behandlung der Gefässzugangsstelle und des Patienten insgesamt,
einschliesslich der nötigen Aufmerksamkeit für andere potenzielle
Blutungsstellen, Einsatz eines an das Gewicht angepassten Bolus und eine
kontinuierliche Infusionsdosis von REOPRO.


In klinischen Studien war die Wahrscheinlichkeit abnehmender
Thrombozytenmengen, einschliesslich schwerer Thrombozytopathien (siehe auch
unten: Erneute Verabreichung) bei Patienten, die mit REOPRO behandelt worden
waren, grösser als bei Patienten, die ein Placebo erhalten hatten.


Die Verabreichung von REOPRO kann zur Bildung humaner, antichimärer
Antikörper (HACA) führen, die potenziell allergische Reaktionen oder
Überempfindlichkeit, (einschliesslich Anaphylaxie), Thrombozytopenien oder
eine verringerte Wirkung bei erneuter Verabreichung hervorrufen kann. In
einer Registrierstudie zur erneuten Verabreichung von REOPRO (1342
Behandlungen bei 1286 Patienten) gab es keine Berichte über schwerwiegende
allergische Reaktionen oder Anaphylaxie. Fälle von Thrombozytopenien traten
in der Studie zur erneuten Verabreichung häufiger auf als in den Studien der
Phase 3 zur erstmaligen Verabreichung. Dies legt nahe, dass die erneute
Verabreichung u. U. mit einer gestiegenen Häufigkeit und Schwere von
Thrombozytopenien verbunden ist. Dieses erhöhte Risiko ging einher mit
Thrombozytopenien in der Vergangenheit bei vergangenen REOPRO-Zuführungen,
einer positiven HACA-Probe an der Basislinie und einer erneuten Verabreichung
innerhalb von 30 Tagen.


In Berichten über unerwünschte Wirkungen nach dem Vertrieb wurden seltene
Fälle von Anaphylaxie bei mit REOPRO behandelten Patienten gemeldet. Wenn
eine Überempfindlichkeit auftritt, ist die Verabreichung von REOPRO sofort
einzustellen, und es sind geeignete Wiederbelebungsmassnahmen einzuleiten.


Da REOPRO das Blutungsrisiko vergrössern kann, darf es in folgenden
klinischen Situationen nicht angewandt werden: aktive innere Blutungen,
kürzliche (innerhalb von sechs Wochen) Magen-Darm-Blutungen oder urogenitale
Blutungen von klinischer Bedeutung, Apoplexie in der Krankengeschichte
innerhalb der letzten zwei Jahre von oder Apoplexie mit einem bedeutenden
neurologischen Restdefizit, Blutungsdiathese, Verabreichung oraler
Gerinnungshemmer innerhalb von sieben Tagen, sofern die Prothrombinzeit
weniger oder gleich dem 1,2-fachen des Kontrollwertes liegt,
Thrombozytopenien (< 100.000 Zellen/pro Mikroliter), vor kurzem (innerhalb
der letzten sechs Wochen) erfolgte schwere Operationen oder Traumen,
intrakranielles Neoplasma, arteriovenöse Fehlfunktion oder Aneurysma, schwere
unkontrollierte Hypertonie, angenommene oder dokumentierte Vorgeschichte von
Vasculitis, Verwendung von intravenösem Dextran vor einem perkutanen
Herzeingriff oder bei geplanter Verwendung während des Eingriffs, bekannte
Überempfindlichkeit gegenüber einem Bestandteil dieses Produktes oder
gegenüber Mäuseproteinen.


REOPRO wurde von Centocor in Malvern, Pa., USA, entwickelt und von
Centocor, B.V. im niederländischen Leiden hergestellt. Eli Lilly and
Company vermarktet und vertreibt das Produkt weltweit, mit Ausnahme von
Japan.

UPDATE 1-Abbott's Humira promising for Crohn's Disease
Mon Oct 31, 2005 02:31 PM ET (Adds details, background, stock price)
NEW YORK, Oct 31 (Reuters) - Abbott Laboratories Inc. (ABT.N: Quote, Profile, Research) on Monday said its rheumatoid arthritis drug Humira showed positive results in a late-stage trial in treating the chronic intestinal condition Crohn's Disease.
The suburban Chicago company said 83 percent of patients who received the drug every week stayed disease-free for one year, while the rates of remission were 74 percent for those taking it every other week and 44 percent for those taking a placebo.
Abbott is presenting the results from its Phase 3 extension study, involving 55 patients whose moderate to severe disease went into remission after receiving Humira for four weeks, at a gastroenterology meeting this week.
William Sandborn of the Mayo Clinic's inflammatory bowel disease clinic called the results promising.
"There is no cure for Crohn's disease ... the next critical step is maintaining clinical remission, thereby preventing disease flares that may disrupt patients' lives," he said.
Crohn's Disease is a chronic inflammation of the intestinal wall that causes frequent diarrhea, cramping and abdominal pain.
Humira, which was recently approved to treat psoriatic arthritis, is Abbott's biggest product with global sales of $356 million during the third quarter.
Abbott shares were up 29 cents at $43.05 in afternoon trading on the New York Stock Exchange.

UCB Presents Positive Cimzia(TM) Results From Pivotal Phase III Crohn's Disease Trial at Major U.S. Medical Meeting
HONOLULU, Oct. 31 /PRNewswire/ -- A single 400 mg injection of Cimzia(TM) (certolizumab pegol, CDP 870) every four weeks was effective in maintaining control of the signs and symptoms of Crohn's disease following induction therapy, according to pivotal phase III research presented this week at the annual meeting of the American College of Gastroenterology.
The study, entitled PRECiSE 2, found that a significantly higher proportion of patients who responded to an induction regimen of 400 mg Cimzia(TM) at weeks zero, two and six, were able to maintain clinical response and achieve remission by week 26 when given a single injection every four weeks, compared to those treated with placebo. A regulatory submission for the treatment of Crohn's disease is planned in the US during the first quarter of 2006.
"As there is considerable unmet need in the treatment of Crohn's disease, it is important that the research community continue to explore new therapies," said William J. Sandborn, MD, professor of medicine, Mayo Clinic College of Medicine, Rochester, MN, PRECiSE study investigator. "These data are exciting because it shows that Cimzia(TM) holds significant promise in meeting many of these needs."

Crohn's disease is a chronic inflammatory bowel disorder that affects approximately one million people in the US and Europe alone.(1,2) Because there is no cure, treatment is focused on suppressing the inflammatory response that is at the root of its cause. Cimzia(TM) is a biologic agent that has been designed to inhibit the production of tumor necrosis factor alpha (TNF-alpha), a protein involved in the inflammation process.
   Study Highlights    -- 64 percent of the 668 patients enrolled in the trial responded to      induction therapy by week 6. Those who responded were randomized to      receive maintenance treatment with either Cimzia(TM) (n=216) or placebo      (n=212).    -- 62.8 percent of patients receiving Cimzia(TM) maintenance therapy      sustained an overall clinical response throughout the 26-week study      period, compared to 36.2 percent with placebo.    -- The primary endpoints of PRECiSE 2 trial were met with statistical      significance, irrespective of C-reactive protein (CRP, a marker of      inflammation) status or prior exposure to anti-TNF therapy.    -- 47.9 percent of patients receiving Cimzia(TM) maintenance therapy were      in clinical remission at week 26, compared to 28.8 percent with      placebo.    -- Adverse events were mostly mild to moderate with the most common being      headache (maintenance: certolizumab 6.9 percent; placebo 6.6 percent).      Serious non-CD-related infections were observed in both the Cimzia(TM)      (certolizumab pegol, CDP 870) (3 events) and placebo (2 events)      treatment groups.  



The PRECiSE clinical trial program is composed of four studies (PRECiSE 1, 2, 3 and 4). In addition to PRECiSE 2, the detailed results of which were presented at ACG, PRECiSE 1 is a 26-week double-blind, placebo-controlled trial, and represents the first long-term fully placebo-controlled clinical trial of a biologic in Crohn's disease. PRECiSE 1 successfully met its primary endpoints with statistical significance. As expected from a study with such a challenging trial design, top-line results were of lower magnitude than observed in the PRECiSE 2 trial. The detailed analysis of the PRECiSE 1 data is still ongoing, with results planned for presentation at a forthcoming gastroenterology congress. PRECiSE 3 and 4 are both 24-month, open-label trials for patients who participated in either PRECiSE 1 or 2, assessing the longer-term safety and tolerability of Cimzia(TM), and are currently ongoing.
Methods
The 26-week PRECiSE 2 study was designed to assess the safety and efficacy of Cimzia 400 mg for the maintenance of clinical response after open-label induction therapy in patients with mild to moderate Crohn's disease. Those who responded by week six were randomized to receive either a once-monthly maintenance dose of certolizumab 400 mg or placebo. Clinical response was defined as a 100 point drop in the Crohn's Disease Activity Index (CDAI), which measures the disease severity by taking into account a number of factors such as intensity of symptoms, medication and general well-being. The primary endpoint was the percentage of patients at week 26 with a C-reactive protein (CRP, a marker of inflammation) level greater than or equal to 10 mg who maintained a clinical response after successful induction. Major secondary endpoints included remission (CDAI less than or equal to 150) in those with a CRP level greater than or equal to 10mg, and response and remission in the overall treatment population.
About Crohn's Disease
Crohn's disease is a chronic disorder that causes inflammation of the gastrointestinal tract, most commonly at the end of the small intestine (the ileum) and beginning of the large intestine (the colon). Common symptoms include diarrhea, fever, abdominal pain and weight loss. Although it can occur at any age, it primarily impacts young adults between the ages of 15 and 35. Because it is a chronic illness, patients experience an ongoing cycle of symptom "flare-ups" and periods of remission, when symptoms disappear or are controlled.(1) This cycle can impact all aspects of a patient's life, including their pursuit of higher education and relationships with employers, friends and family members.(3)
About Cimzia(TM)
Cimzia(TM) is unique anti-TNF therapy in that it is a humanized antibody Fab' fragment chemically attached to polyethylene glycol (PEG, i.e. PEGylated). PEGylation increases the plasma half-life of certolizumab to approximately two weeks.

FDA Accepts ERBITUX(R) (Cetuximab) sBLA Submission for the Treatment of Squamous Cell Carcinoma of the Head and Neck and Grants Priority Review
ImClone Systems Incorporated (NASDAQ: IMCL) and Bristol-Myers Squibb Company (NYSE: BMY) announced today that the U.S. Food and Drug Administration (FDA) has notified ImClone Systems that it has accepted for filing the Company's supplemental Biologics License Application (sBLA) for ERBITUX(R) (Cetuximab), an IgG1 monoclonal antibody, in the treatment of Squamous Cell Carcinoma of the Head and Neck (SCCHN). The application seeks approval for use of ERBITUX in combination with radiation for locally or regionally advanced head and neck cancer, and as monotherapy in patients with recurrent and/or metastatic disease where prior platinum-based chemotherapy has failed or where platinum-based therapy would not be appropriate.

The Companies also announced that the ERBITUX sBLA has been granted priority review. The FDA grants priority review to biologics that potentially offer a significant therapeutic advance over existing therapies for serious or life-threatening diseases. Based on the priority review designation, the FDA has six months from the submission date of August 30, 2005, to take action on the sBLA filing.

About Head and Neck Cancer

According to the American Cancer Society, approximately 40,000 Americans will be diagnosed with head and neck cancer this year, including cancers of the tongue, mouth, pharynx, and larynx. In addition, it is estimated that more than 11,000 will die from the disease in 2005 in the U.S.

About ERBITUX(R) (Cetuximab)

On February 12, 2004, the FDA approved ERBITUX for use in the United States in combination with irinotecan in the treatment of patients with EGFR-expressing, metastatic colorectal cancer who are refractory to irinotecan-based chemotherapy and for use as a single agent in the treatment of patients with EGFR-expressing, metastatic colorectal cancer who are intolerant to irinotecan-based chemotherapy. The effectiveness of ERBITUX for the treatment of colorectal cancer is based on objective response rates. Currently, no data are available that demonstrate an improvement in disease-related symptoms or increased survival with ERBITUX in metastatic colorectal cancer patients.

ERBITUX binds specifically to the epidermal growth factor receptor (EGFR, HER1, c-ErbB-1) on both normal and tumor cells, and competitively inhibits the binding of epidermal growth factor (EGF) and other ligands, such as transforming growth factor-alpha. The EGFR is constitutively expressed in many normal epithelial tissues, including the skin and hair follicle. Over-expression of EGFR is also detected in many human cancers including those of the colon and rectum.

Important Safety Information

Severe infusion reactions, rarely fatal and characterized by rapid onset of airway obstruction (bronchospasm, stridor, hoarseness), urticaria, and hypotension, have occurred in approximately 3% (20/774) of patients with the administration of ERBITUX. Most reactions (90%) were associated with the first infusion of ERBITUX despite the use of prophylactic antihistamines. Severe infusion reactions require immediate and permanent discontinuation of ERBITUX therapy. Caution must be exercised with every ERBITUX infusion as there were patients who experienced their first severe infusion reaction during later infusions. A 1-hour observation period is recommended following the ERBITUX infusion. Longer observation periods may be required in patients who experience infusion reactions.

Severe cases of interstitial lung disease (ILD), which was fatal in one case, occurred in less than 0.5% of 774 patients receiving ERBITUX.

Dermatologic toxicities, including acneform rash (11% of 774 patients, grade 3/4), skin drying and fissuring, inflammatory or infectious sequelae (e.g., blepharitis, cheilitis, cellulitis, cyst) and paronychial inflammation (0.4% of 774 patients, grade 3) were reported. Sun exposure may exacerbate any skin reactions.

Hypomagnesemia has been reported with ERBITUX when administered as a single agent and in combination with multiple different chemotherapeutic regimens. The incidence of hypomagnesemia (both overall and severe (NCI CTC grades 3 & 4)) was increased in patients receiving ERBITUX alone or in combination with chemotherapy as compared to those receiving best supportive care or chemotherapy alone based on ongoing, controlled clinical trials in 244 patients. Approximately one-half of these patients receiving ERBITUX experienced hypomagnesemia and 10-15% experienced severe hypomagnesemia. Electrolyte repletion was necessary in some patients, and in severe cases, intravenous replacement was required. Patients receiving ERBITUX therapy should be periodically monitored for hypomagnesemia, and accompanying hypocalcemia and hypokalemia during, and up to 8 weeks following the completion of, ERBITUX therapy.

Other serious adverse events associated with ERBITUX in clinical trials (n=774) were fever (5%), sepsis (3%), kidney failure (2%), pulmonary embolus (1%), dehydration (5% in patients receiving ERBITUX plus irinotecan, 2% receiving ERBITUX as a single agent) and diarrhea (6% in patients receiving ERBITUX plus irinotecan, 0.2% with ERBITUX as a single agent).

Additional common adverse events seen in patients receiving ERBITUX plus irinotecan (n=354) or ERBITUX as a single agent (n=420) were acneform rash (88%/90%), asthenia/malaise (73%/48%), diarrhea (72%/25%), nausea (55%/29%), abdominal pain (45%/26%), vomiting (41%/25%), fever (34%/27%), constipation (30%/26%) and headache (14%/26%).

MedImmune files to test lupus drug in humans
Friday October 14, 3:07 pm ET


MedImmune and its New Jersey partner have filed with federal regulators to begin human testing on a drug for treating lupus and potentially other autoimmune disorders.
In November 2004, Gaithersburg-based MedImmune (NASDAQ: MEDI - News) and Princeton-based Medarex (NASDAQ: MEDX - News) formed a collaboration to develop antibody drugs targeting interferon-alpha.

Preclinical data indicate that levels of interferon-alpha are elevated in many patients with lupus or other autoimmune disorders. The drug, called MEDI-545, binds to interferon-alpha and has been shown to neutralize its activity in preclinical studies.

To begin Phase I human tests on the lupus drug, MedImmune and Medarex filed an investigational new drug application with the Food and Drug Administration. Once that application is approved, the biotechnology companies begin the long, and costly, process of taking a product candidate through the development cycle.

Under the terms of their agreement, MedImmune currently has full responsibility for all ongoing development activities on the lupus drug.

The filing, says MedImmune Senior Director of Research of Anthony Coyle, "reflects MedImmune's commitment to the development of new treatments targeting inflammatory and autoimmune diseases and marks another milestone in our efforts to advance our pipeline of product candidates."

The Lupus Foundation of America estimates about 1.5 million people in the United States suffer from some form of lupus, which is a chronic inflammatory disease that causes the body to attack its own tissue and organs, including the skin, joints, blood and kidneys.

MedImmune has local competition in the race to bring new lupus drugs to market.

Rockville-based Human Genome Sciences (NASDAQ: HGSI - News) on Oct. 5 reported that a midstage clinical trial found its lupus drug to be safe and well tolerated, but the drug did not meet its primary efficacy goals. That news caused stock in Human Genome Sciences to fall about 30 percent.

Neue europäische Studie zum Einsatz von Cetuximab als adjuvante Therapie bei kolorektalem Karzinom
Montag 31. Oktober 2005, 09:04 Uhr



PARIS, Frankreich, October 31 /PRNewswire/ --


- 13. Annual European Conference on Clinical Oncology


In einer grossen europaweiten Zusammenarbeit wird ab heute untersucht,
ob Cetuximab in Kombination mit Oxaliplatin-haltiger Chemotherapie (FOLFOX-
4) bei völliger Resektion im Erkrankungsstadium III nach der Operation die
Anzahl der Krankheitsrückfälle reduziert und die Überlebenszeit verlängert.
Wissenschaftler der Fédération Francophone de Cancérologie Digestive (FFCD)
leiten diese Intergroup-Studie in Zusammenarbeit mit der European
Organisation for Research and Treatment ANZEIGE
 
of Cancer (EORTC) sowie mit den
nationalen Gruppen, die an den europaweiten Studien zur Krebsstruktur im
Verdauungskanal (PETACC) beteiligt sind. Diese von der FFCD finanzierte
Studie wird 2.000 Patienten rekrutieren und soll vor Ende dieses Jahres
beginnen.


Circa 25 Prozent der 370.000 Patienten in Europa, die jedes Jahr mit
kolorektalem Karzinom diagnostiziert werden, befinden sich im
Erkrankungsstadium III.(1,2) In diesem Stadium hat der Tumor bereits
begonnen, sich durch die Darmwand und in die angrenzenden Lymphknoten
auszuweiten. Eine Operation mit nachfolgender Chemotherapie hat die
Überlebenszeit zwar signifikant verbessert, jedoch werden etwa ein Drittel
der Patienten aller Wahrscheinlichkeit nach innerhalb der nächsten drei
Jahre einen Krankheitsrückfall erleiden. (3) Daher ist es wichtig, dass
neue Therapien untersucht werden, welche die Rückfallrate mindern und die
Überlebenszeit verbessern.


In der PETACC-8-Studie werden Patienten mit völlig resektiertem
kolorektalen Karzinom im Erkrankungsstadium III randomisiert ausgewählt und
erhalten entweder Cetuximab in Kombination mit FOLFOX-4 oder FOLFOX-4
alleine. Die Therapien werden für die Dauer von 6 Monaten durchgeführt.


Etwa 340 führende Zentren in ganz Europa, einschliesslich Frankreich,
Deutschland, Belgien, Spanien, Grossbritannien, Österreich, Italien,
Dänemark, Portugal, Schweden und andere Länder, werden Patienten
rekrutieren. Weitere Informationen erhalten Sie von
Martina Schneider, PETACC-8-Projektmanager (+33-3-80-39-34-83,
Martina.Schneider@u-bourgogne.fr).


"Mehr und mehr Menschen entwickeln kolorektales Karzinom und mindestens
30 Prozent der Patienten mit völliger Resektion im Erkrankungsstadium III
werden rückfällig. Daher müssen wir die Chancen der Patienten durch die
Aufnahme neuer gezielter Therapien in unsere Behandlungsstrategien
verbessern", sagte der leitende Prüfarzt der Studie, Dr. Julien Taïeb vom
Groupe Hospitalier Pitié Salpêtrière, Paris. "Wir hoffen sehr, dass die
Kombination Cetuximab und FOLFOX, die sich bereits bei Patienten im
fortgeschrittenen Erkrankungsstadium als wirksam erwies, auch die
krankheitsfreie Überlebenszeit nach der Operation signifikant verbessern
wird."


Cetuximab zielt speziell auf den epidermalen Wachstumsfaktorrezeptor
(EGFR) ab, der oft in Krebszellen vorhanden ist. Durch Blockieren des EGFR
wird verhindert, dass der Tumor weiter wächst und die Krebszellen sich auf
andere Organe im Körper ausweiten. Cetuximab hat auch eine verbesserte
Wirkung von Strahlen- und Chemotherapie gezeigt.


Die am häufigsten verschriebene adjuvante Chemotherapie (nach der
Operation) ist seit geraumer Zeit 5-Fluorouracil/Leucovorin (5-FU/LV).
Oxaliplatin ist eine neue Generation von Chemotherapie, die in Kombination
mit 5-FU/LV die dreijährige krankheitsfreie Überlebensrate im
Erkrankungsstadium III von 65,3 Prozent (5-FU/LV allein) auf 72,2 Prozent
(Oxaliplatin und 5-FU/LV; FOLFOX) erhöhen konnte.(3) Cetuximab zeigte
konsistent hohe Responseraten und längere progressionsfreie
Überlebenszeiten, wenn es in den späteren Stadien von kolorektalem Karzinom
verwendet wurde,(4) und es wird erwartet, das Oxaliplatin das Wachstum und
die Ausbreitung von Krebszellen in den früheren Erkrankungsstadien, in
denen die Chance für eine Heilung noch grösser ist, wirksam verhindert.
Daher erwarten die Prüfärzte, dass die zusätzliche Verabreichung von
Cetuximab einen Meilenstein bei der Heilung von noch mehr Patienten
darstellen wird, ohne deren Sicherheit zu kompromittieren.

Über PETACC (Pan-European Trials in Alimentary Tract Cancer)


Umfangreiche klinische Studien sind erforderlich, um die signifikanten
Vorteile einer neuen adjuvanten Chemotherapie für die Behandlung von
Darmkrebs aufzuzeigen. In Anbetracht der grossen Anzahl an Patienten, die
rekrutiert werden sollen, haben sich mehrere Kooperationsgruppen unter dem
Namen PETACC zusammengeschlossen. Dieses Konsortium besteht aus über einem
Dutzend europäischer nationaler und internationer Kooperationsgruppen. Jede
Gruppe kann Projekte vorschlagen, die dann von der PETACC-
Generalversammlung diskutiert und genehmigt werden. Der betriebliche Teil
der PETACC-Studien ist aus Gründen der Einheitlichkeit zentralisiert
(Verfahren, Qualitätssicherung usw.), aber jede Gruppe behält ihre
Individualität innerhalb des allgemeinen Rahmens bei.


Über die FFCD


Die Fédération Francophone de Cancérologie Digestive (FFCD) ist ein
französischer Akademikerverband, der 1991 von Fachpersonal für
Krebserkrankungen im Verdauungstrakt (Gastroenterologen, Onkologen,
Radiologen, Chirurgen, Pathologen usw.) gegründet wurde.
Zu den Forschungstätigkeiten zählen hauptsächlich das Design neuer
klinischer Studien durch das wissenschaftliche Kommitee der FFCD, die
Durchführung von klinischen Phase-II- und Phase-III-Studien sowie die
Errichtung eines biologischen Forschungszentrums für Translational Research
(Umsetzung von Erkenntnissen aus dem Labor zum Krankenbett).


Die FFCD ist der rechtliche Sponsor der PETACC-8-Studie.


Über kolorektales Karzinom


Das kolorektale Karzinom ist die dritthäufigste bösartige
Krebserkrankung weltweit.(5) Allein in Europa erkrankten im Jahr 2002 mehr
als 370.000 Menschen an diesem Leiden, was für 12 Prozent aller
Krebskranken und ca. 200.000 Tote verantwortlich war.(1)

Dendreon's Second Randomized Phase 3 D9902A Trial of PROVENGE Extends Survival in Patients With Advanced Prostate Cancer
PARIS, Oct. 31 /PRNewswire-FirstCall/ -- Dendreon Corporation today announced that final results of its second Phase 3 study (D9902A) of PROVENGE(R) (sipuleucel-T), the Company's investigational active cellular immunotherapy for the treatment of prostate cancer, were presented here today during a late-breaking clinical trials session at ECCO 13-the European Cancer Conference. Researchers concluded that these results are consistent with the results from the Company's first Phase 3 study (D9901). The Company recently announced plans to submit a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) to market PROVENGE based on discussions of these data with the FDA.

"The combined data from the trials of PROVENGE versus placebo demonstrate that active immunotherapy favorably impacts survival in men with asymptomatic, metastatic, androgen-independent prostate cancer," reported Celestia S. Higano, M.D., director and associate professor of the Genitourinary Oncology Clinical Research Group at the University of Washington, Seattle, who presented the data. "Given the favorable side effect profile, PROVENGE may provide a useful alternative for men prior to initiating chemotherapy."

In the D9902A study, the three-year final survival analysis in the intent- to-treat population of the double-blind, placebo-controlled study of PROVENGE in 98 men with asymptomatic, metastatic, androgen-independent (hormone- refractory) prostate cancer showed those patients who received PROVENGE had a 19.0 month median survival time compared with only 15.7 months for the patients who were randomized to receive a placebo. This represents a 3.3 month or 21 percent improvement in median survival for patients who were randomized to receive PROVENGE compared to placebo (p-value = 0.331, log-rank; HR = 1.3). This hazard ratio implies that patients receiving placebo have a relative risk of dying that is 30 percent higher than those patients receiving PROVENGE. A Cox multivariate regression analysis of overall survival, which adjusts for imbalances in prognostic factors known to influence survival, met the criteria for statistical significance (p-value = 0.023; adjusted HR = 1.9). The hazard ratio observed in this analysis was consistent with that seen in the Company's first Phase 3 study, D9901. In addition, at the three- year final follow up, 32 percent of the men in the PROVENGE group were alive compared to only 21 percent of the men in the placebo group, a 52 percent improvement in the survival rate.

As in previous studies, PROVENGE was well tolerated with the most common adverse events reported being fever and chills lasting for one to two days.

As reported earlier this year, the final three-year follow up of the D9901 study of PROVENGE in 127 men with asymptomatic, metastatic, androgen- independent prostate cancer showed a median survival benefit of 21 percent or 4.5 months and a three-fold improvement in survival at 36 months (p-value = 0.010; HR = 1.7). In addition, a Cox multivariate regression analysis was used to test the validity of the survival benefit seen in this study. The results showed that patients receiving placebo had a relative risk of dying that is more than twice as high as those patients receiving PROVENGE (p-value = 0.002; adjusted HR = 2.1).

Dr. Higano also presented an integrated analysis of the data from studies D9901 and D9902A, which showed a statistically significant survival benefit in the overall intent-to-treat population of 225 patients. In this analysis, patients receiving PROVENGE had a median survival of 23.2 months compared to 18.9 months for patients in the placebo group, a 4.3 month or 23 percent improvement in median survival. This analysis was statistically significant by both log rank (p-value = 0.011; HR = 1.5) and Cox multivariate regression analysis of overall survival (p-value = 0.0006; adjusted HR = 1.8). In addition, at the three-year final follow up, 33 percent of the men who received PROVENGE were alive compared to only 15 percent of the men who received placebo, a greater than 100 percent improvement.

"We were pleased to see a statistically consistent and meaningful survival benefit across the three analyses," said Robert M. Hershberg, M.D., Ph.D., Dendreon's chief medical officer. "We will be working closely with the FDA to complete our BLA and to bring PROVENGE to market for men with advanced stage prostate cancer who currently have few appealing treatment options available to them."

About PROVENGE (sipuleucel-T)

The generic name "sipuleucel-T" has been approved by the United States Adopted Names (USAN) Council for Dendreon's investigational active cellular immunotherapy (ACI) for prostate cancer, previously known as APC8015. If approved, sipuleucel-T will be marketed as PROVENGE.

PROVENGE (sipuleucel-T) is an investigational product that may represent the first in a new class of active cellular immunotherapies (ACIs) that are uniquely designed to stimulate a patient's own immune system. ACIs hold promise because they may provide patients with a meaningful survival benefit with low toxicities. PROVENGE targets the prostate cancer antigen, prostatic acid phosphatase (PAP), which is found in approximately 95% of prostate cancers. PROVENGE is in late-stage clinical development for the treatment of patients with early-stage and advanced prostate cancer. In clinical studies, patients typically received three infusions over a one-month period as a complete course of therapy.

Phase III MabThera maintenance trial in lymphoma shows positive results earlier than expected
Category: Lymphoma/Leukemia News
Article Date: 31 Oct 2005





Roche has been informed by the European Organisation for Research and Treatment of Cancer (EORTC) that a phase III study[1] in relapsed indolent non-Hodgkin's lymphoma (NHL) evaluating the use of MabThera (rituximab) as maintenance treatment has shown positive results earlier than expected. MabThera maintenance therapy is administered over two years and aims to prevent disease recurrence.

“Our study confirms that MabThera maintenance therapy is beneficial for patients that have already received MabThera as part of their initial therapy” said lead investigator, Professor Marinus van Oers M.D., from the Academic Medical Center of the University of Amsterdam. “The full results of the trial will be presented as an oral presentation at this year's annual conference of the American Society of Hematology (ASH) in Atlanta.”

Non-Hodgkin's lymphoma affects 1.5 million people worldwide. Indolent NHL, representing about 45% of NHL patients, is a slow developing but serious cancer of the lymphatic system.

“We look forward to the presentation of the full trial results in December“, said Eduard Holdener, Head of Pharma Development at Roche. “Based on this new information MabThera maintenance therapy could well become the new standard treatment in this disease.”

Roche is currently preparing an application to the European Authorities to request a label extension for maintenance therapy, expected to be submitted in the fourth quarter 2005, making this treatment option available to all patients.

About the study

The international cooperative group phase III trial was conducted in 18 countries and recruited 465 patients with relapsed indolent NHL. Patients were randomized to receive either six cycles of MabThera in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy, or CHOP chemotherapy alone. Patients who responded to initial treatment were then randomised to MabThera maintenance therapy (one infusion every three months for two years) or no further treatment.

A pre-planned analysis in early 2004 showed that induction treatment with MabThera plus CHOP was significantly superior to CHOP alone and that two years of MabThera maintenance therapy substantially improved progression-free survival compared to observation. Therefore, the trial was suspended as it had reached both primary endpoints. At that time the results were not mature enough to determine if MabThera maintenance therapy also prolongs progression-free survival for the subgroup of patients who already had received MabThera plus CHOP as initial treatment. The EORTC therefore originally decided to amend the study to evaluate this outstanding question.

An updated analysis of the study data with additional follow-up of approximately 18 months has now demonstrated a significant benefit of MabThera maintenance therapy for patients who initially received MabThera plus CHOP. Consequently, the EORTC, following the recommendation by the Independent Data Monitoring Committee, has stopped the study and decided to report the results at the ASH meeting in December.

About MabThera

MabThera is a therapeutic antibody that binds to a particular protein - the CD20 antigen - on the surface of normal and malignant B-cells. It then recruits the body's natural defences to attack and kill the marked B-cells. Stem cells (B-cell progenitors) in bone marrow lack the CD20 antigen, allowing healthy B-cells to regenerate after treatment and return to normal levels within several months.

MabThera was initially indicated as a single-agent treatment for relapsed or refractory indolent NHL, and received European approval in March 2002 for the treatment of aggressive NHL in combination with CHOP chemotherapy. In August of 2004 MabThera received European approval for first line treatment of Indolent NHL in combination with CVP chemotherapy. MabThera is known as Rituxan in the United States, Japan and Canada. More than 700,000 patients have been treated with MabThera worldwide to date.

Genentech and Biogen Idec co-market MabThera in the United States, and Roche markets MabThera in the rest of the world, except Japan, where MabThera is co-marketed by Chugai and Zenyaku Kogyo Co. Ltd.

Multi-million dollar deal to benefit medical research
Category: Biology/Biochemistry News
Article Date: 29 Oct 2005





The drug, HUMIRA®, is so far used to treat rheumatoid arthritis but has other applications in the pipeline. The Scripps Research Institute and the American company, Stratagene will share US$64m as part of the agreement.

The technology, developed by the MRC Laboratory of Molecular Biology, was the basis for the setting up of Cambridge Antibody Technology Ltd in 1990 as a business.

The American pharmaceutical company, Abbott has agreed to pay (via Cambridge Antibody Technology) US$255 million in place of the future royalties the MRC, Scripps Research and Stratagene would have received on sales of HUMIRA®. In addition, Cambridge Antibody Technology will pay the MRC a further US$7.5m over five years from 2006, providing that HUMIRA® remains on the market.

The MRC patents cover a series of inventions made by Sir Gregory Winter and his colleagues at the MRC Laboratory of Molecular Biology during the late 1980s and early 1990s for making 'human monoclonal antibodies'.

Sir Gregory commented "Our inventions originated from pure curiosity-driven and long-term basic research funded at the Laboratory of Molecular Biology by the MRC. Provided such research is intelligently and quickly exploited, it can pay handsome dividends for medicine, UK industry and human health. It can also generate considerable royalty income, which ploughed back into science will help generate the medicines and industries of the future."

Professor Colin Blakemore, the MRC Chief Executive added "This deal is great news for British science. It shows the wonderful achievements that can be won for human health when the Medical Research Council works with industry. It also gives the UK an opportunity to reap the rewards from our past discoveries to make the fullest possible investment in future science. The agreement will help us give our scientists new research facilities and the best laboratories. We also want to invest in initiatives which will help us to translate cutting-edge scientific research into healthcare for all".

The related Scripps Research patents cover inventions which hailed from the laboratory of Dr. Richard A. Lerner, president of the Institute. Dr. Lerner said, "It is wonderful to see the work from our two laboratories come together to benefit so many patients suffering from a variety of serious conditions."

Although the scientists from MRC and Scripps Research were scientific competitors in earlier years, they pooled their inventions in Cambridge Antibody Technology to facilitate exploitation of the technology for creation of new medicines.

Monoclonal Antibodies. These are often referred to as 'magic bullets'. They are custom-made protein molecules that have been designed to home in on specific targets. Dr César Milstein and Dr George Köhler discovered how to make monoclonal antibodies at the MRC Laboratory of Molecular Biology in Cambridge. Their work earned them the Nobel prize in Physiology or Medicine in 1984. It has led to therapeutic products for breast cancer, leukaemia, asthma and transplant rejection; many more are in late stage clinical trials.

HUMIRA® is the first fully human monoclonal antibody to be approved by the American Food and Drug Administration and was developed using combinatorial antibody libraries, on which the founding of Cambridge Antibody Technology was based. It is currently approved only for treatment of rheumatoid arthritis, but it is also in clinical trials for use in other indications including Phase III trials for use in juvenile rheumatoid arthritis, Crohn's disease, psoriatic arthritis and ankylosing spondylitis.

The Medical Research Council (MRC) is a national organization funded by the UK tax-payer. Its business is medical research aimed at improving human health; everyone stands to benefit from the outputs. The research it supports and the scientists it trains meet the needs of the health services, the pharmaceutical and other health-related industries and the academic world. MRC has funded work which has led to some of the most significant discoveries and achievements in medicine in the UK. About half of the MRC's expenditure of approximately £500 million is invested in its 40 Institutes, Units and Centres. The remaining half goes in the form of grant support and training awards to individuals and teams in universities and medical schools. Web site at: www.mrc.ac.uk

Amgen: Cancer Therapy Slows Tumor Growth
Thursday November 3, 2:50 pm ET
By Heidi Vogt, AP Business Writer  
Amgen Says Its Experimental Colon Cancer Therapy Slowed Tumor Growth in Late-Stage Study


NEW YORK (AP) -- Biotech drug maker Amgen Inc. said Thursday that its experimental colon cancer therapy, a potential rival to ImClone Inc.'s Erbitux, significantly slowed tumor growth in a late-stage study.
ADVERTISEMENT


Amgen shares rose $3.33, or 4.5 percent, to $77.23 in afternoon trading on the Nasdaq while shares of Abgenix Inc., its partner in the drug, jumped $3.73, or 40 percent to $13.10. Shares of New York-based ImClone dove $7.39, or 20 percent, to $28.72.

Amgen said tumors grew 46 percent more slowly in patients taking its Panitumumab drug than in those who received palliative care -- a standard that can include a number of treatments but did not include chemotherapy drugs in this study. The 463-patient trial consisted of patients with colon cancer that had spread and who had failed standard chemotherapy.

The results exceeded the company's target for a 33 percent decrease in tumor growth.

Thousand Oaks, Calif.-based Amgen said the study results mean its drug is the first of its class to improve the likelihood that patients will live without their disease getting worse. ImClone's Erbitux approval is based on a different measure -- tumor shrinkage. Amgen said its drug also decreased tumor size, a measure it had set as a secondary endpoint, and that those results were comparable with mid-stage trials.

Panitumumab and Erbitux work in generally the same way, by binding to a protein that is associated with tumor growth. However, Panitumumab is derived solely from human antibodies, while Erbitux is partly made up of mouse antibodies.

"The benefit with a fully human antibody is that a human's body is less likely to reject it," said Citigroup analyst Elise Wong. "With Panitumumab you have very low infusion reactions and very low rates hypersensitivity."

Though she cautioned that the broad top-line data make firm conclusions difficult, Wong said the results appear "very robust," adding that "it should prove to be a very competitive product to Erbitux" if just based on the safety advantage and its less-frequent dosing regimen (every other week versus once a week).

Wong also noted that Amgen's study group consisted of patients that had more advanced cancer than those that Erbitux used to gain its approval last February.

Merrill Lynch analyst Eric Ende had said that ImClone shares would be worth between $28 and $31 if the Amgen trial met its endpoint, arguing that a positive study result could lead to Panitumumab dominating the colon cancer market despite Erbitux's head start.

Amgen said it plans to start the process of applying for approval from the Food and Drug Administration by the end of the year with the aim of completing its submission in the first quarter of 2006.

Abgenix of Fremont, Calif., helped develop panitumumab with its animal research technology -- a method of genetically engineering mice for use in creating antibody therapies. The company stands to get a share of the drug's profits if it is approved.

Panitumumab is also in clinical trials for lung and kidney cancer, while ImClone is investigating Erbitux for head and neck cancer.

BOSTON (MarketWatch) -- Shares of Abgenix Inc. jumped Thursday, while Amgen Inc. scored more modest gains, as they said that a drug they've been developing has been shown to be highly effective in slowing the progression of advanced colorectal cancer.

ABGXABGX, , ) rocketed 38% to close at $12.90, while Amgen shot up 5% to $77.51.

Amgen and Abgenix announced that patients in a Phase III clinical trial who took the drug panitumumab, an antibody-based therapy, had a 46% decrease in the progression of their cancerous tumors as opposed to those who didn't receive the therapy.

The companies tested the drug in 463 patients with advanced colorectal cancer who had already failed standard chemotherapy treatment.

Amgen and Abgenix said they hope to finish filing for regulatory approval of panitumumab during the first quarter of 2006.

Shares of rival ImClone Systems (IMCL:
sank on the news, dropping as much as 19%. Imclone and partner Bristol-Myers Squibb (BMY: BMY

Hugin-News: GPC Biotech AG
Mittwoch 9. November 2005, 09:31 Uhr


Deutsche Zulassungsbehörde erteilt GPC Biotech (Xetra: 585150 - Nachrichten) die Genehmigung den monoklonalen Krebs-Antikörper 1D09C3 in zusätzlicher klinischer Phase-1-Studie zu testen
Corporate news- Mitteilung verarbeitet und übermittelt durch Hugin. Für den Inhalt der Mitteilung ist der Emittent verantwortlich.

--------------------------------------------------

--------------

Martinsried/München und U.S.-Forschungs- und Entwicklungsstandorte in Waltham/Boston, Mass., und Princeton, N.J., 9. November ANZEIGE
 
2005 - Die GPC Biotech AG (Frankfurt: GPC; TecDAX 30; NASDAQ (NASDAQ: Nachrichten) : GPCB) gab heute bekannt, dass das Paul-Ehrlich-Institut (PEI) die Genehmigung erteilt hat, in Deutschland die klinischen Studien im Menschen mit dem monoklonalen Krebsantikörper 1D09C3 zu beginnen. Das PEI ist die deutsche Zulassungsbehörde für biologische und hämatologische Arzneimittel. Die offene Phase-1-Studie untersucht 1D09C3 bei Patienten, die an einem resistenten B-Zell-Tumor leiden oder nach einer zuvor durchgeführten Standardtherapie einen Rückfall erlitten haben. Sie untersucht ein anderes Verabreichungsschema als die bereits in der Schweiz und Italien laufende Phase-1-Studie. Ziel der klinischen Studie ist es, die Sicherheit und Verträglichkeit des Antikörpers bei Patienten zu ermitteln und eine Empfehlung für die Dosierung sowie für das Verabreichungsschema für weiterführende Phase-2-Studien zu geben. Diese zweite Phase-1-Studie wird an der Universitätsklinik Köln durchgeführt und von Prof. Dr. Michael Hallek, Direktor der Abteilung für Innere Medizin, geleitet. Dr. Marcel Rozencweig, Senior Vice President, Drug Development von GPC Biotech, sagte: "Ich freue mich, dass wir die Genehmigung des Paul-Ehrlich-Instituts erhalten haben, mit dieser Studie beginnen zu können. Dies ermöglicht es uns, das Phase-1-Studienprogramm für unseren monoklonalen Krebsantikörper auszuweiten. Wir freuen uns sehr darüber mit Professor Hallek zusammen arbeiten zu können. Er ist ein weltweit anerkannter Experte in der Behandlung von Leukämien und Lymphomen und arbeitet bereits seit mehreren Jahren mit GPC Biotech an der Entwicklung von 1D09C3." Dr. Rozencweig sagte weiter: "Trotz der Fortschritte in der Behandlung von Lymphomen gibt es noch immer einen großen medizinischen Bedarf an Therapien für Patienten, die einen Rückfall erlitten haben oder bereits resistent gegen andere Behandlungen geworden sind. 1D09C3 scheint einen anderen Wirkmechanismus zu haben als die Medikamente, die derzeit gegen Blutkrebs eingesetzt werden. Deshalb hat 1D09C3 das Potenzial zu einer wichtigen neuen Behandlungsmöglichkeit zu werden." Über 1D09C3: 1D09C3 ist ein Anti-MHC (Major Histocompatibility Complex) Klasse II monoklonaler Antikörper. Er bindet an spezifische Zelloberflächenrezeptoren und führt so zum gezielten Absterben aktivierter, sich vermehrender MHC-Klasse-II-positiver Tumorzellen, darunter B-Zell- und T-Zell-Lymphome sowie weitere Blutkrebsarten. Im Jahr 2004 erkrankten schätzungsweise über 54.000 Menschen in den USA und ungefähr 64.000 Menschen in der EU am Non-Hodgkin-Lymphom, der häufigsten Lymphomart. Daten belegen, dass 1D09C3 den programmierten Zelltod auslöst, ohne hierfür ein voll funktionsfähiges Immunsystem zu benötigen. 1D09C3 befindet sich derzeit in einem klinischen Phase-1-Studienprogramm, in welchem der Antikörper in wichtigen europäischen Krebszentren bei Patienten getestet wird, die an einem resistenten B-Zell-Lymphom leiden oder nach einer zuvor durchgeführten Standardtherapie einen Rückfall erlitten haben. Zu den B-Zell-Lymphomen zählen auch die Hodgkin- und Non-Hodgkin Lymphome. GPC Biotech wurde von der europäischen Zulassungsbehörde EMEA für 1D09C3 zur Behandlung von Hodgkin-Lymphom der Orphan-Drug-Status zugesprochen. Weiterführende Informationen zu 1D09C3 sind in der Rubrik "Anti-Krebs-Programme" auf der Webseite des Unternehmens unter www.gpc-biotech.com abrufbar.

Die GPC Biotech AG ist ein biopharmazeutisches Unternehmen, das in der Entdeckung und Entwicklung neuartiger Krebsmedikamente tätig ist. Nach der Durchführung eines "Special Protocol Assessment" bei der U.S.-Zulassungsbehörde FDA und dem Erhalt eines "Scientific Advice" der europäischen Zulassungsbehörde EMEA, befindet sich der am weitesten in der Entwicklung fortgeschrittene Produktkandidat Satraplatin in einer Phase-3-Zulassungsstudie als Zweitlinien-Chemotherapie zur Behandlung von Patienten mit hormonresistentem Prostatakrebs. Die FDA hat Satraplatin für diese Indikation zudem den "Fast-Track-Status" erteilt. GPC Biotech entwickelt außerdem einen monoklonalen Antikörper mit neuartigem Wirkmechanismus gegen verschiedene Blutkrebsarten, der sich derzeit in der klinischen Phase 1 befindet, und betreibt mehrere Medikamentenentdeckungs- und -entwicklungsprogramme im Bereich der Kinase-Hemmer. GPC Biotech hat eine mehrjährige Allianz mit der ALTANA Pharma AG in deren Rahmen GPC Biotech mit dem ALTANA Research Institute in den USA zusammenarbeitet. Diese Allianz bildet für GPC Biotech eine Umsatzbasis bis Mitte 2007. Sitz der GPC Biotech AG ist Martinsried/Planegg. Die U.S.-Tochtergesellschaft, GPC Biotech Inc., hat Forschungs- und Entwicklungseinrichtungen in Waltham/Boston (Massachusetts) und Princeton (New Jersey).

Mittwoch 9. November 2005, 07:51 Uhr


Kopenhagen, Dänemark, November 9 (ots/PRNewswire) - Genmab A/S (CSE: GEN) gab heute die Ergebnisse für den Neumonatszeitraum bis einschliesslich 30. September 2005 bekannt. Für diesen Zeitraum meldete Genmab (Kopenhagen: GEN.CO - Nachrichten) die folgenden Ergebnisse:

- Die Nettoverluste in Höhe von 293 Millionen DKK (ungefähr 47 Millionen USD) entsprachen den Nettoverlusten von 293 Millionen DKK (ungefähr 47 Millionen USD) im selben Zeitraum im Jahr 2004. In den ersten neun Monaten des Jahres 2005 betrug der Nettoverlust pro Aktie ANZEIGE
 
damit 9,57 DKK (ungefähr 1,54 USD) im Vergleich zu 11,57 DKK (ungefähr 1,87 USD) im entsprechenden Vorjahreszeitraum. - Der Betriebsverlust belief sich auf 323 Millionen DKK (ungefähr 52 Millionen USD). Der Betriebsverlust für den gleichen Zeitraum im Jahr 2004 betrug dagegen 318 Millionen DKK (ungefähr 51 Millionen USD). - Das Nettofinanzeinkommen erreichte eine Gesamthöhe von 30 Millionen DKK (ungefähr 5 Millionen USD) gegenüber einem Nettofinanzeinkommen in Höhe von 25 Millionen DKK (ungefähr 4 Millionen USD) in den ersten neun Monaten im Jahr 2004. - Genmab schloss den Neunmonatszeitraum mit einem Kassenstand von 1,394 Milliarden DKK (ungefähr 225 Millionen USD) ab. Dies entspricht einer Nettosteigerung von 236 Millionen DKK (ungefähr 38 Millionen USD) in den ersten neun Monaten des Jahres 2005. - Die Erlöse in den ersten neun Monaten dieses Jahres beliefen sich auf insgesamt 45 Millionen DKK (ungefähr 7 Millionen USD). Im Vergleichszeitraum des Jahres 2004 wurden dagegen keine Erlöse erwirtschaftet.


Höhepunkte

Im dritten Quartal konnten die folgenden geschäftlichen und wissenschaftlichen Leistungen erzielt werden:


- Einleitung einer zweiten Phase in der Untersuchung von HuMax-CD20 für die Behandlung von Patienten mit chronischem Gelenkrheumatismus (rheumatoide Arthritis/RA), bei denen die Behandlung mit einer oder mehreren DMARD-Mitteln (Disease Modifying Anti-Rheumatic Drugs) versagt hat. - Genmab gewährte Serono (Virt-X: SEO.VX - Nachrichten) im August die exklusiven weltweiten Rechte zur Entwicklung und Kommerzialisierung von HuMax-CD4. Genmab erhielt Lizenzgebühren in Höhe von 20 Millionen USD, und Serono investierte 50 Millionen USD in Stammaktien von Genmab mit 18 % Agio. Die Zahlungen an Genmab einschliesslich aller Meilensteine können sich auf insgesamt 215 Millionen USD belaufen, und Genmab stehen Tantiemen für den weltweiten Verkauf von HuMax-CD4 zu. - Im September wurden positive Zwischenergebnisse für die erste und zweite Phase der HuMax-CD20-Untersuchung bezüglich des Einsatzes bei Patienten mit chronischer Lymphozytenleukämie (CLL) vorgelegt. Bei Patienten, die mit der höchsten Dosis behandelt wurden, konnte eine Reaktionsrate von 52 % beobachtet werden. - Bo Kruse wurde mit Wirkung vom Oktober 2005 zum Vice President, Chief Financial Officer von Genmab ernannt.


Finanzprognose

Genmab überarbeitet derzeit seine Finanzprognose für das Jahr 2005. Aufgrund der verbesserten Betriebseffizienz und günstiger Entwicklungen in den Devisenkursen haben wir unsere Vorhersage für den Kassenstand zum Jahresende 2005 auf ungefähr 1,225 Milliarden DKK revidiert, was einer Steigerung von ungefähr 67 Millionen DKK gegenüber dem Kassenstand zum Jahresende 2004 entspricht.

Zusätzlich haben wir unsere Prognosen für Betriebs- und Nettoverluste angepasst und gehen jetzt davon aus, dass diese Werte ungefähr 440 Millionen DKK bzw. 410 Millionen DKK betragen werden. Wir haben zwar von Serono die gesamten Lizenzgebühren für HuMax-CD4 in Höhe von 20 Millionen USD im dritten Quartal erhalten, haben uns jedoch zu einer konservativen Verbuchung unserer Erlöse entschlossen, die höchsten Buchhaltungsnormen gerecht wird. Aus diesem Grund haben wir die Anrechnung eines Teils dieser Lizenzgebühren verschoben und werden diesen Anteil bis zum Jahresende 2007 linear abschreiben.

Änderungen der Prognosen können vor allem aufgrund der Terminierung und der Vielfältigkeit klinischer Aktivitäten, damit zusammenhängender Kosten und der Schwankungen in den Devisenkursen notwendig werden. Bei den Prognosen wird ausserdem davon ausgegangen, dass im verbleibenden Zeitraum des Jahres 2005 keine weiteren Vereinbarungen getroffen werden, die die Ergebnisse wesentlich beeinflussen könnten.

Konferenzschaltung

Genmab wird morgen, am Mittwoch, den 9. November 2005, eine Telefonkonferenz abhalten, bei der die Ergebnisse des dritten Quartals besprochen werden. Die Konferenzschaltung findet zu folgenden Ortszeiten statt:

15:30 MEZ (mitteleuropäische Zeit) 14:30 WEZ (britische Zeit) 09:30 EST (amerikanische Ostküstenzeit) Die Telefonkonferenz wird auf Englisch abgehalten.

Roche's MabThera helps arthritis patients
Wed Nov 16, 2005 01:44 AM ET
ZURICH, Nov 16 (Reuters) - Cancer drug MabThera improves the symptoms of patients with rheumatoid arthritis who had failed to benefit from other forms of treatment, Roche Holding AG (ROG.VX: Quote, Profile, Research) said on Wednesday.
In data released at a medical meeting in San Diego, Roche said that its MabThera drug significantly improved all measures of efficacy for rheumatoid arthritis patients for six months following a single course of two infusions of the drug.

The patients tested had previously failed to benefit from so-called anti-TNF therapies which are designed to block an inflammation-causing protein.

The drug is already indicated as a treatment for non-Hodgkin's lymphoma, or lymph cancer. It was developed by Genentech Inc. (DNA.N: Quote, Profile, Research) , majority-owned by Roche, and Biogen Idec (BIIB.O: Quote, Profile, Research) and is marketed in the U.S. as Rituxan.

CORRECTED - UPDATE 1-J&J, Schering-Plough RA drug shows promise in trial
Wed Nov 16, 2005 04:02 PM ET
(In story headlined "Update 1-J&J, Schering-Plough RA drug shows promise in trial," please read in paragraph 9, "An FDA advisory panel backed Bristol-Myers Squibb Co.'s treatment, Orencia, for rheumatoid arthritis ..." instead of "Bristol-Myers Squibb Co. won approval for its rheumatoid arthritis drug Orencia ..." (Correcting to show drug has not yet received FDA approval.)
BOSTON, Nov. 16 (Reuters) - Johnson & Johnson (JNJ.N: Quote, Profile, Research) and Schering-Plough Corp. (SGP.N: Quote, Profile, Research) said on Wednesday that their experimental rheumatoid arthritis drug showed promise in a mid-stage trial.

The companies said that more than 60 percent of patients taking the drug, golimumab, combined with the common treatment methotrexate, saw an improvement in their symptoms of at least 20 percent after 16 weeks.

Results of the phase II trial, presented this week at the annual meeting of the American College of Rheumatology, showed that a quarter of patients receiving the combination treatment achieved remission of their symptoms.

Schering-Plough's shares rose about 1 percent to $19.31 in early trading on the New York Stock Exchange. Johnson & Johnson's shares rose a similar amount to $63.44.

Golimumab is designed to work by blocking an inflammation-causing protein known as tumor necrosis factor. Johnson & Johnson already has a drug on the market -- Remicade -- that blocks the same protein. Amgen Inc.'s (AMGN.O: Quote, Profile, Research) Enbrel and Abbott Laboratories Inc.'s (ABT.N: Quote, Profile, Research) Humira attack the same target.

TNF-inhibitors have been among the most successful of all biotechnology drugs and rheumatoid arthritis, which affects more than 2 million people in the United States, is one of the most hotly-contested disease areas.

Genentech Inc. (DNA.N: Quote, Profile, Research) and Biogen Idec Inc. (BIIB.O: Quote, Profile, Research) recently filed for marketing approval to sell their cancer drug Rituxan as a treatment for rheumatoid arthritis in patients who have failed to respond to TNF blockers.

Roche Holding AG (ROG.VX: Quote, Profile, Research) , which is developing a drug called MRA together with Chugai Pharmaceutical Co Ltd (4519.T: Quote, Profile, Research) sees rheumatoid arthritis as a major area for potential future growth.

An FDA advisory panel backed Bristol-Myers Squibb Co.'s (BMY.N: Quote, Profile, Research) treatment Orencia for rheumatoid arthritis earlier this year to treat patients who fail to respond to one or more other therapies. The FDA is still considering the panel's recommendation that the agency approve the drug.

Orencia is the first of a new class of drugs know as T-cell co-stimulation modulators. The drug works by inhibiting activation of T-cells, components of the immune system involved in inflammation.

Golimumab is being co-developed by Schering-Plough and J&J's Centocor unit.

Alexion also said it will assess what impact the results might have on a second Phase III clinical trial currently testing pexelizumab in patients who had just undergone angioplasty.

"We are clearly disappointed that pexelizumab did not meet its primary endpoint," said Leonard Bell, Alexion's chief executive officer, in a release. "We look forward to completing an analysis of the data and obtaining a more in-depth understanding of these results."

In related news, Alexion also said it was expecting initial results from a Phase III clinical trial for its drug eculizumab for the treatment of a rare blood disorder during the first quarter 2006.

The timing of Alexion's announcement made a research note from Banc of America Securities seem a bit prescient, although the firm's initiation of the stock with a neutral rating may be in jeopardy following the Wednesday's results.

Banc of America asserted that Wall Street didn't fully appreciate the challenges facing Alexion, commercially and clinically. The analysts said they believed the pexelizumab trial for bypass surgery had only about a 50% chance of being successful. They added they believed the on-going Phase III trial for eculizumab had about a 70% chance of success.

Prior to the news, the firm projected pexelizumab would have peak sales of $500 million, if approved. It estimated peak sales of eculizumab would be around $150 million.

 GROWING GLOBAL CONCERN about a possible pandemic stemming from avian flu have put the spotlight on several drug companies that may have treatments, notably Switzerland's Roche, maker of the highly sought-after anti-viral, Tamiflu.
AVI BioPharma (AVII), a little-known U.S. biotechnology firm, also could be a beneficiary of flu fears because its novel "antisense" drugs may be effective in combating the flu virus, as well as hepatitis C and a range of bio-terror threats, including the dreaded Ebola virus.

Antisense drugs potentially offer an elegant antidote to viral diseases because they're designed to enter cells and eliminate viruses by preventing their replication. The drugs, which act by blocking critical viral genetic sequences, may be more potent than anti-virals such as protease inhibitors, which seek to inhibit a protein needed for viral replication. AVI's specialty is single-strand RNA viruses, which include Ebola, hepatitis C and the flu.
 
Based in Portland, Ore., AVI has developed a drug, now in early clinical trials, to treat hepatitis C. Its drug to prevent restenosis, or the reclogging of arteries that can occur after angioplasty, is undergoing a clinical trial in Europe. The results from the hepatitis C trial are expected late this year or early in 2006, and the restenosis-trial data are likely next year.

The hepatitis trial, combining the first and second phases of the three trials typically required by the Food and Drug Administration, admittedly is small, involving about 40 sick patients. But, if that trial proves a success, AVI would stand a good chance of forming a potentially lucrative partnership with a major drug maker. Such a pact could help lift the company from obscurity and power its stock, which now languishes around $3 a share.

While AVI has little support on Wall Street, its fans believe it could be a big winner. "AVI has created and patented a core technology that has multiple applications that span everything from infectious disease to restenosis to muscular dystrophy and cancer," says Richard Macary, a managing partner at Corporate Insights, an independent research firm in New York. Macary owns AVI shares.

AVI clearly is a speculative stock. It has no drugs on the market, and minimal revenues other than government grants. As such, it has had to rely on dilutive equity financings, including a $24 million deal earlier this year, to fund itself. AVI has a modest market value of about $140 million, based on 44 million shares outstanding. It has $31 million of cash, enough to last more than a year, given its current annual cash-burn rate of about $22 million.

Unlike most other biotech companies with depressed shares, AVI hasn't had any failures in clinical trials. The company arguably has too much on its plate, and its management has been faulted for not telling its story well to investors and for not moving quickly enough with clinical trials in order to commercialize its products.

What attracts Macary is AVI's technology and the broad range of diseases its drugs presumably could treat, including avian flu. Once AVI's technology is "proven in one area," he says, Wall Street and the drug industry will take notice. That could come with the Phase I/II trial involving AVI's hepatitis C drug. AVI is taking on a difficult disease — a leading cause of liver failure — that may affect 200 million to 300 million people worldwide, including as many as four million in the U.S.

Hepatitis C represents a multibillion-dollar opportunity for any company that can come up with a better treatment than the current standard, a long, toxic and costly regimen involving Interferon and ribavirin that is ineffective in about half of patients. Many drug companies are working on hepatitis C drugs, including Vertex Pharmaceuticals (VRTX

Page 2 of 2)

AVI has developed treatments for a range of bio-terror threats, including the Ebola and Marburg viruses, anthrax and ricin, as well as West Nile virus and dengue fever. A U.S. Senate committee has approved an appropriation of $22 million to the company to pursue these drugs.
If the funds materialize in 2006, it will help AVI move forward with the testing necessary to seek FDA approval. The company has a strong relationship with the U.S. Defense Department and its top lab, the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID), at Fort Detrick, Md. AVI's Ebola and Marburg treatments have been effective in animals, including primates, but haven't yet been tested in humans.

AVI also has had success in preclinical experiments with a drug to combat the flu. The company now wants to expand its research to animals, and later to humans.

Wall Street analysts generally are cool to AVI, partly because the history of antisense drugs hasn't been a happy one for investors. The FDA failed to approve antisense cancer drugs from Genta (GNTA) and Isis Pharmaceuticals (ISIS) in the past two years, casting a pall over any biotech company pursuing such therapies.

One of AVI's biggest critics on the Street is Legg Mason biotech analyst Edward Nash, who has a Sell rating on the stock. "So we ask ourselves, why would investors invest in AVI with no near-term hope of profitability when they could invest in other biotech companies that have near-term, late-stage clinical, and/or commercialization milestones," Nash wrote in a recent note, titled "AVII: AVI (an) is for the birds."

AVI's situation could change dramatically if its hepatitis C drug trial meets the company's goal of substantially reducing the viral count in diseased patients. Major drug companies are desperate for products, and hepatitis C is considered one of the largest opportunities. Biotech firms with promising drugs, even those not yet in Phase III trials, are reaching lucrative deals with Big Pharma. AVI's chief executive, Denis Burger, says the company is likely to partner with one of several big drug makers if the hepatitis C trial goes well.

AVI was formed in 1980, and its drug platform is supported by more than 100 patents. The company's top executives and directors have significant experience in the drug and biotech industries. Burger, who has been AVI's CEO since the company went public in 1997, acknowledges it's a show-me story. "With the high-profile antisense failures, the Street is leery of the word antisense. Pharmaceutical companies and investors are leery," he says.

Burger says AVI's third-generation Neugene technology differs fundamentally from antisense drugs developed by rivals. AVI drugs use a patented, synthetic chemical backbone to deliver their gene-blocking payload. This structure is designed to prevent the human body's tendency to break them down before they reach target cells.

Antisense drugs also have to overcome other biochemical hurdles, including the ability to cross cellular barriers and then block specific genetic targets. The drugs need to work without causing severe side effects, as safety has been a problem with rivals' drugs. "We've completed 11 human clinical trials involving 250 patients, and we've not had a single drug-related adverse event," Burger says.

AVI can develop a drug quickly once it knows the genetic code of the target virus. With the flu, it strives to target a critical section of the virus that is common to multiple strains. Because the flu virus mutates, a new vaccine must be developed yearly.

Small Firm, Big Targets
AVI Biopharma is developing drugs based on its patented anti-viral technology to combat hepatitis C, which lacks strong existing treatments, and a variety of bioterrorist threats, including Ebola.

Neues aus der Welt der Antikörper und Immunother. 2244171yahoo.smartmoney.com/barrons/images/20051114b3.gif" style="max-width:560px" >

If its technology works, AVI could develop drugs for a host of ailments that have a genetic cause. GlaxoSmithKline (GSK), for instance, is using AVI's technology to develop a treatment for muscular dystrophy. Other applications could include diabetes and multiple sclerosis.

In 2004, a worker at the USAMRIID lab was stuck by a needle while working with Ebola, prompting fears the worker might contract the deadly disease. AVI formulated a drug within days that got special FDA approval, though the worker proved to be unharmed. AVI was then able to test the drug in primates who were given a fatal dose of Ebola, and 75% survived.

The U.S. government is eager for drugs to combat a range of bio-terror threats because few treatments now exist. Ebola, which causes a hemorrhagic fever that is usually fatal, largely has been confined to central Africa. It is transmitted through direct contact with the blood or bodily secretions of those afflicted. The fear is that terrorists could produce an airborne form of Ebola and then seek to infect a city.

If AVI's Ebola and other bio-terror treatments are deemed sufficiently promising, the government could commission the company to produce a significant amount of the drugs for stockpiling. The government already has an $877 million contract with VaxGen (VXGN), a California biotech, to make 75 million doses of an anthrax vaccine. The advantage of AVI's treatment over a vaccine is that it can be used immediately when an outbreak of the disease occurs. Vaccines typically aren't effective for those who already have contracted a disease, and they can take weeks to provide immunity to healthy people. The chief of immunology at USAMRIID, Sina Bavari, said recently that favorable animal tests involving AVI drugs "represent important progress for the potential treatments of these deadly bio-threats," according to an AVI press release.

The Bottom Line
AVI BioPharma's shares trade for $3, but could soar if the company's flu, hepatitis and restenosis drugs move toward FDA approval. That could also lead to a deal with Big Pharma.  
 

One of the knocks against AVI is that it lacks a major drug partner. In 2001, AVI traded up to $12 share after it partnered with Medtronic (MDT), which planned to use AVI's restenosis drug for a new stent. That partnership lapsed in 2004 without producing a drug-coated stent, and its failure has been interpreted as a sign that the AVI drug isn't effective. Drug-coated stents from Boston Scientific (BSX) and Johnson & Johnson (JNJ) now dominate the market. Stents are used as scaffolding to hold open arteries after they've been cleared of blockages. Drug-coated stents have reduced the incidence of restenosis, or the reclogging of arteries, compared with bare-metal stents.

In Europe, AVI is testing its drug in conjunction with bare-metal stents, commonly used on the continent, to see if the combination can achieve similar success at much lower cost. The AVI drug is injected.

A U.S. Phase II trial in 2003 found that AVI's Resten drug, when delivered via catheter, was effective in preventing restenosis. "It's a very good drug," says Dr. Nicholas Kipshidze, a physician and researcher at Lenox Hill Hospital in New York, which conducted the 2003 trial. "We got very good results with inferior delivery. It's less toxic than any other drug we are using. I still believe that Resten will play a role in the stent" market. Kipshidze consults for AVI, but doesn't own stock.

The Street has written off AVI's restenosis drug, just as it has downplayed the potential of its other products. The biotech industry is full of hype, hope and frequent disappointment. Like most biotechs, AVI amounts to a lottery ticket. But, in this case, the payoff just might be huge.

Behandlung mit subkutanem (SC) MabCampath(R) (Alemtuzumab) bei Patienten mit fludarabin-refraktärer CLL effektiv und unbedenklich
Montag 12. Dezember 2005, 09:09 Uhr



Atlanta, December 12 /PRNewswire/ --


- Laut Zwischenanalyse ist SC MabCampath so effektiv und gut verträglich
wie IV-Therapie



Gemäss den Zwischenergebnissen der Phase-II-UKCLL02-Studie ist
MabCampath(R) (Alemtuzumab) in subkutaner (SC) Form sowohl effektiv wie auch
gut verträglich im Vergleich zu historischen Patientengruppen, die sich
intravenösen (IV) Behandlungen für fludarabin-refraktäre, chronisch
lymphatische Leukämie (CLL) unterzogen. Die Ergebnisse, die bei der 47.
Jahrestagung der American Society of Hematology (ASH) vorgestellt wurden,
bewiesen, dass fast Anzeige
 

die Hälfte aller mit SC MabCampath behandelten Patienten
entweder mit partiellem oder vollständigen Ansprechen reagierten, wobei
manche Patienten die MRD-Negativität erreichten (MRD = minimale
Resterkrankung).


"Obwohl MabCampath IV erfolgreiche Ansprechraten zwischen 33 und 50
Prozent erzielt hat, können die Infusionsreaktionen und zweistündigen
Behandlungen, die dreimal pro Woche während eines Zeitraums von 12 Wochen
stattfinden, sowohl in Hinblick auf Nebenwirkungen wie auch den Zeitaufwand
für die Patienten problematisch werden", so Peter Hillmen, M.B, Ch.B,
Facharzt für Hämatologie am Allgemeinkrankenhaus Leeds in Leeds,
Grossbritannien. "Diese Ergebnisse sind für Patienten und Ärzte
gleichermassen sehr ermutigend, da sie zu der Annahme führen, dass SC
MabCampath so effektiv wie die herkömmliche IV-Behandlung sein könnte. Bei
diesen Patienten, deren Behandlung sich als überaus schwierig erwiesen hat,
wird die SC-Behandlung besser vertragen, wobei die einfachere
Verabreichungsmethode ein zusätzlicher Bonus ist."



Ergebnisse der Studie


Von den bis dato 44 ersten untersuchten Patienten haben 36 die Therapie
vollständig abgeschlossen. Die Gesamtansprechrate für MabCampath und die
Fludarabin-Therapie lag bei 44 Prozent (39 Prozent bei ausschliesslich
Campath), wobei drei Patienten in der MabCampath-Monotherapiephase ein
vollständiges Ansprechen (zwei MRD-negativ und eines MRD-positiv) und 11
Patienten ein partielles Ansprechen (einschliesslich einem MRD-negativen
Patienten, der zytopenisch blieb) erreichten. Zwei Nicht-Responder erzielten
partielles Anspechen, als sie mit einer Kombinationstherapie von MabCampath
und oral verabreichtem Fludarabin behandelt wurden, während ein Nicht-
Responder vollständiges Ansprechen erreichte (MRD-positiv). Darüberhinaus
sprachen 20 Patienten mit einer genetischen Disposition zu schlechtem
Ansprechen auf Chemotherapie (p53-Dysfunktion oder Deletion) gut auf die
Behandlung mit MabCampath an.


Die häufigsten Nebenwirkungen, die während der anfänglichen Verabreichung
von MabCampath beobachtet wurden, waren örtlich begrenzte, erythematöse
Hautreaktionen, Fieber und Starre, wobei alle Reaktionen innerhalb von 48
Stunden nach der Behandlung nachliessen. Thrombozytopenie Grad 3+ und
Neutropenie wurden bei je 16 und 25 Patienten beim Monotherapiearm von
MabCampath, bzw. bei einem und zwei Patienten beim kombinierten Therapiearm
beobachtet. Zu den potenziell gravierenden Infektionen, die bei der
MabCampath-Monotherapie auftraten, gehörten die CMV-Reaktivation
(Zytomegalovirus), febrile Neutropenie, invasive Pilzkrankheiten und
Lungenentzündung. Bei den Kombinationstherapie-Patienten trat lediglich
CMV-Reaktivation auf, und alle CMV-Reaktivationen konnten erfolgreich mit
antiviraler Therapie behandelt werden.


Im Vergleich hierzu wurden gewisse ungünstige Prozesse, die mit der
intravenösen Verabreichung einhergingen, insbesondere Schüttelfrost,
Hautausschläge und Übelkeit/Erbrechen, durch die subkutane Verabreichung von
MabCampath drastisch reduziert oder gar eliminiert.


Das mittlere Alter der Patienten lag bei 66 Jahren (zwischen 41 und 79),
wobei 36 Patienten dreimal pro Woche bis zu 24 Wochen (abhängig von der alle
6 Wochen erfolgenden Knochenmark-Beurteilung) eine 30mg-Dosis von SC
MabCampath erhielten. Patienten, die während der subkutanen Verabreichung
kein Ansprechen erreichten, konnten für je drei Tage alle vier Wochen 40mg/m2
orales Fludarabin in Kombination mit SC MabCampath bekommen.



Näheres über chronisch lymphatische Leukämie (CLL)


CLL ist die häufigste Form der Leukämie bei Erwachsenen und befällt
jährlich etwa 120.000 Menschen in Europa und den USA, wobei Patienten im
Alter von 50 Jahren und darüber am häufigsten betroffen sind.
Charakteristisch für CLL ist die Ansammlung funktionell nicht ausgereifter
weisser Blutkörperchen (Lymphozyten) im Knochenmark, dem Blut, Lymphgewebe
und anderen Organen. Es befinden sich zwei Arten von Lymphozyten im Blut, die
B-Zellen und die T-Zellen. Bei etwa 95 Prozent der CLL-Fälle sind krebsartige
B-Zellen im Spiel. Da diese B-Zellen eine längere Lebensdauer als normal
haben, beginnen sie, sich aufzubauen und die normalen, gesunden
Blutkörperchen zu "verdrängen". Die Anhäufung funktionell nicht ausgereifter
Zellen im Knochenmark schliesst die Bildung von gesunden Zellen aus und kann
sich tödlich auswirken. Zu den Symptomen zählen Müdigkeit, Knochenschmerzen,
Nachtschweiss sowie Appetit- und Gewichtsverlust. Wenn das Knochenmark
betroffen ist, kann dies aber auch zu einer Schwächung des Immunsystems
führen, wodurch der Patient einer höheren Infektionsgefahr ausgesetzt ist.



Informationen zu MabCampath(R) (Alemtuzumab)


MabCampath, das in den USA auch unter dem Namen Campath(R) vertrieben
wird, ist der erste und einzige für CLL zugelassene humanisierte monoklonale
Antikörper und das erste Medikament mit bewährter Wirkung bei CLL-Patienten,
die weder auf Alkylantien noch die Behandlung mit Fludara (
Fludarabinposphaten) ansprechen. Keine andere Therapie hat bei dieser
Patientengruppe ähnliche Wirkung gezeigt. Die Wirkungsweise von
MabCampath/Campath und herkömmlichen Behandlungsmethoden ist vollkommen
unterschiedlich, da sich ersteres gezielt gegen das CD52-Antigen der malignen
Lymphozyten richtet. Die hierdurch in Gang gesetzten Prozesse führen zur
Lysis, also dem Tod oder der Auflösung der bösartigen Zellen. Diese Prozesse
führen dann zur Entfernung der malignen Lymphozyten aus dem Knochenmark, dem
Blut und anderen betroffenen Organen, was dann wiederum eine gesteigerte
Lebenserwartung nach sich ziehen kann.


Die bei dieser Indikation auftretenden Nebenwirkungen von MabCampath
können gut unter Kontrolle gebracht werden, wenn das eventuelle Auftreten
opportunistischer Infektionen genau überwacht und entsprechende
prophylaktische Massnahmen dagegen getroffen werden. Diese Nebenwirkungen
sind vorhersehbar, kontrollierbar und reversibel. Darüberhinaus können
Patienten wieder ihre eigenen gesunden Blutkörperchen bilden, da MabCampath
die Stammzellen im Knochenmark nicht angreift.

Roche will Erweiterung des Anwendungsgebiets von MabThera beantragen
Montag 12. Dezember 2005, 19:12 Uhr


BASEL (dpa-AFX) - Roche (Virt-X: ROG.VX - Nachrichten) wird bei den europäischen Behörden ein Zulassungsgesuch zur Erweiterung des Anwendungsgebiets seines Krebsmittels MabThera einreichen. Wie der Schweizer Pharmakonzern unter Berufung auf neue klinische Daten an diesem Montag mitteilte, bewirkt eine zweijährige Erhaltungstherapie mit dem Präparat eine drastische Verbesserung der Überlebenschancen von Patienten mit indolentem Non-Hodgkin-Lymphom (NHL). Die Erhaltungstherapie soll das Wiederauftreten dieser bösartigen Erkrankung des ANZEIGE
 
Lymphsystems verhindern. Der Pharmachef von Roche, William Burns, sprach von einem "bislang ungekannten Überlebensvorteil bei dieser als unheilbar geltenden Krebskrankheit". Allein in Westeuropa werde das indolente NHL jährlich bei 20.000 Patienten neu diagnostiziert und rund 40.000 Patienten mit dieser Erkrankung werden behandelt./hi/zb

Amgen will Abgenix für 22,50 Dollar je Aktie in bar plus Schulden kaufen

Der weltgrößte Biotechnologiekonzern Amgen <AMGN.NAS> <AMG.FSE> (Nachrichten/Aktienkurs) will den Konkurrenten Abgenix <ABGX.NAS> <ANX.ETR> (Nachrichten) für 22,50 US-Dollar je Aktie in bar übernehmen. Der Kaufpreis liege damit bei 2,2 Milliarden Dollar, teilte Amgen am Mittwoch in Thousand Oaks nach Börsenschluss mit. Zudem sollen die Schulden des Biotechnologie-Spezialanbieters übernommen werden.

Die Abgenix-Aktie schloss am Mittwoch mit einem Plus von 3,24 Prozent bei 14,65 Dollar. Nachbörslich legte sie 41,23 Prozent auf 20,69 Dollar zu, bevor sie vom Handel ausgesetzt wurde. Amgen-Anteile verbilligten sich unterdessen etwas.

Durch die Akquisition, die im ersten Quartal des kommenden Jahres abgeschlossen sein soll, erhalte Amgen den vollen Zugang zum gemeinsam entwickelten Krebsmedikament Panitumumab. Amgen schätzt, dass der jährliche Spitzenumsatzes des Medikaments, dessen Entwicklung den Angaben zufolge weite fortgeschritten ist, bis zu zwei Milliarden Dollar betragen könnte.

Das Unternehmen geht davon aus, dass die Übernahme den Gewinn je Aktie vor Sonderposten in den Jahren 2006 und 2007 zwischen fünf und zehn Cent belasten wird. Danach werde die Akquisition im Falle eines kommerziellen Erfolgs von Panitumumab den Gewinn je Aktie vor Sonderposten positiv beeinflussen.

Zur Höhe der Schulden, die Amgen übernimmt, machten die Unternehmen keine Angaben. Den zuletzt veröffentlichten Zahlen zufolge hatte Abgenix per Ende September neben einer ausstehenden Wandelanleihe von knapp 450 Millionen Dollar rund 85 Millionen Dollar ausstehende Schulden./zb/hi

hier noch etwas ausführlicher.

News of the deal, disclosed after Wednesday's close, was warmly received Thursday, with shares of the biotechnology giant (AMGN:
) jumping 4% to $79.99, while Abgenix (ABGX: ABGX
rocketed 28% to $21.71.

Amgen and Abgenix said they have signed a definitive merger agreement that calls for Amgen to pay $2.2 billion in cash, or $22.50 share, and to assume Abgenix's debt.

Amgen, with a market capitalization of $94.8 billion, is the largest biotechnology company in the world next to Genentech (DNA:
DNA
) , which is partially owned by Roche. Genentech had a market capitalization of $99.6 billion, as of Wednesday evening.

Amgen and Abgenix have been collaborating on developing two major drug candidates, most notably the cancer therapy panitumumab. They're also working on denosumab, a treatment for osteoporosis and bone cancer.

Amgen said it was particularly interested in panitumumab, which it says could have peak sales of more than $2 billion. The drug still must be approved by the Food and Drug Administration.

Amgen noted in its statement that by acquiring Abgenix, it will eliminate the need to pay future royalties on those drugs if and when they are approved. In early November, the companies unveiled favorable Phase III clinical data for panitumumab as a therapy for the treatment of colorectal cancer in patients who had failed on standard chemotherapy regimens.

Amgen and Abgenix expect to apply for U.S. regulatory approval of panitumumab during the first quarter of 2006. They added they also plan testing the therapy for the treatment of head and neck cancers.

That news could spell trouble for rival ImClone Systems (IMCL:

FinancialsMore BMYBMY, , ) have been running Phase III clinical trials for Erbitux for the treatment of head and neck cancers.

Abgenix is best known for its XenoMouse technology, which allows mouse antibodies to be used as therapies in humans through genetic manipulation.

Amgen said that as a result of the merger, it expects earnings to be diluted by 5 cents to 10 cents a share in 2006 and 2007. If panitumumab is successfully launched, the deal should be accretive to dilutive earnings after 2007.

The two companies don't anticipate significant layoffs as a result of the merger, they said.

Imclone Systems Shares Down on Report
Monday December 5, 1:50 pm ET  
Imclone Systems Shares Fall After Analyst Forecasts Stiff Competition for Erbitux


NEW YORK (AP) -- Shares of Imclone Systems Inc. slipped Monday after one analyst predicted that a competing cancer treatment may usurp U.S. market share from Erbitux in the next three to four years.
Imclone shares fell 81 cents, or 2.5 percent, to $31.69 in afternoon trading on the Nasdaq, after dropping as low as 7 percent this morning.

In a research note, SG Cowen & Co. analyst Eric Schmidt said that he expects panitumumab, a cancer drug developed by biotech companies Amgen Inc. and Abgenix Inc., to gain U.S. approval and launch by the third quarter of 2006. Combined with favorable clinical trial data and a less frequent dosing regimen, Schmidt believes that U.S. doctors will have an incentive to adopt panitumumab over Erbitux.

The analyst cited data where tumor growth was hindered by 43 percent in patients given panitumumab, comparable to Erbitux. However, Schmidt said that panitumumab is given intravenously once every two to three weeks compared with Erbitux, which must be given once a week.

With the convenience of less frequent dosing and a lower incidence of infusion toxicities, Schmidt said that a majority of his sources estimated that panitumumab will grab 60 percent to 70 percent of the colorectal cancer treatment market in about three to four years.

Imclone sells Erbitux with marketing partner Bristol-Myers Squibb Co. Both Erbitux and panitumumab are antibodies that inhibit epidermal growth factor receptor, a protein found on the surface of many cancer cells. Annual sales of Erbitux, currently the only anti-EGFR antibody on the U.S. market, are around $450 million, and the U.S. market for the drug class is expected to grow to $750 million to $1.25 billion by 2008.

Shares of Amgen fell 46 cents to $80.32 and Abgenix shares rose 30 cents, or 2.1 percent, to $14.37 on the Nasdaq. Bristol-Myers Squibb shares dipped 8 cents to $21.80 on the New York Stock Exchange.

Cancer vaccine has strong response in young girls
Saturday December 17, 10:18 am ET
By Ransdell Pierson


NEW YORK (Reuters) - Girls aged 10 to 14 who received GlaxoSmithKline Plc's (London:GSK.L - News) vaccine to prevent infection with the virus that causes cervical cancer had immune responses twice as strong as women 15-25 years old given the vaccine, the company said on Saturday, describing results of a late-stage trial.

Glaxo said the first published data from a Phase III trial of its Cervarix vaccine suggest it may provide the strongest and most-prolonged protection if given to girls at very young ages, long before they encounter the sexually transmitted virus.

"The concentrations of antibodies to the virus were twice as high in the bloodstreams of the young girls," said Gary Dubin, a senior research official at Glaxo who was the lead author on the study.

Antibodies are immune-system proteins that seek out and destroy bacteria and viruses. Vaccines, by introducing the body to snippets of specific bacteria or viruses, train the body to crank out tailor-made antibodies that attack them.

Dubin said the trial was not designed to confirm actual effectiveness of the vaccine because few girls in the 10 to 14 age group are yet sexually active. Instead, he said the immune response is the best "surrogate" indicator of the vaccine's potential ability to protect them from prolonged infection with the virus.

Results of the trial were presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Washington, D.C.

The Glaxo-financed trial, conducted in Europe and Russia, involved 158 healthy girls aged 10-14 and 458 women aged 15-25 who received three doses of the vaccine over a six month period.

Cervarix, which has not yet been submitted for regulatory approvals, is one of the most important experimental products being developed by the British drugmaker. It is expected to eventually compete with a similar Merck and Co. (NYSE:MRK - News) vaccine, Gardasil, that is already awaiting approval from U.S. and European regulators.

Like Gardasil, the Glaxo product blocks infection with two strains of human papillomavirus that are responsible for about 70 percent of cases of cervical cancer. It is the second most common fatal cancer in women.

Wyeth to Pay at Least $40 Million to Trubion Pharmaceuticals As Part of Deal to Develop Drugs


NEW YORK (AP) -- Wyeth said Tuesday that will pay at least $40 million to biotech drug developer Trubion Pharmaceuticals Inc. as part of a partnership to develop therapies for immune diseases and cancer.

Including performance-related payments, the deal could be worth up to $800 million, said Cavan Redmond, executive vice president and general manager of Wyeth's biopharmaceuticals business.

Redmond said the pact will give it access to Trubion's proprietary "SMIP" technology -- a term that stands for "small modular immuno-pharmaceuticals" and refers to the ability they give scientists to customize proteins.

Wyeth will have the exclusive rights to the specific disease targets the companies settle on, Redmond said.

Seattle-based Trubion is a small biotech company focused on developing therapies for inflammatory diseases and cancer. It was founded in 2002 by Dr. Peter Thompson, who still heads the firm.

Shares of Madison, N.J.-based Wyeth slipped 15 cents to $45.92 in midday trading on the New York Stock Exchange.

Impfstoff gegen Gebärmutterkrebs

06. Januar 2006 Gegen Krebs wird es im kommenden Jahr einen Impfstoff geben. Die aufsehenerregende Nachricht ist nicht allgemeingültig. Sie gilt aber für den Gebärmutterhalskrebs, die zweithäufigste Krebserkrankung und dritthäufigste Krebstodesursache bei Frauen. Die Entwicklung des hochwirksamen Impfstoffs birgt für die betroffenen Unternehmen angesichts der zu erwartenden Nachfrage viele Chancen: Die britische Glaxo Smith Kline (GSK) und die amerikanische Merck & Co. haben einen Markt im Visier, der schon im Jahr 2010 ein Volumen von rund 8 Milliarden Dollar erreichen soll.


An einer Zulassung durch die zuständigen Behörden in Amerika und Europa wird von Fachleuten nicht gezweifelt. Dafür sorgt zum einen die Wirksamkeit des Impfstoffs, zum anderen die hohe Zahl tragisch verlaufender Fälle, die es gibt, obwohl die Krankheit durch regelmäßige Abstriche im frühesten Stadium erkannt werden kann. Jedes Jahr sterben an Gebärmutterhalskrebs 230 000 Frauen auf der Welt.

Erkenntnisse aus Heidelberg



An dem wahrscheinlichen medizinischen und wirtschaftlichen Erfolg hat die deutsche Grundlagenforschung einen entscheidenden Anteil. Die Erkenntnisse, auf denen die Impfstoffe basieren, hatten Mitte der siebziger Jahre Forscher am Deutschen Krebsforschungszentrum (DKFZ) in Heidelberg gewonnen. Dort mußte Harald zur Hausen die damals neue Annahme, der Krebs werde durch ein Virus ausgelöst, jahrelang gegen eine große Zahl von Fachkollegen vertreten. Inzwischen sind die Erkenntnisse Allgemeingut. Und nach den Worten des GSK-Vorstandsvorsitzenden Jean-Pierre Garnier ist der Erfolg des neuen Impfstoffs, der bei den Briten Cervarix heißt, programmiert: „Er ist hundertprozentig wirksam.” Die Zulassung in Europa, der 2007 die Markteinführung folgen soll, wird in den kommenden Monaten beantragt werden.

„In weniger als drei Jahren” auf dem Markt

Auch auf anderen Märkten der Welt sei damit zu rechnen, daß das Produkt „in weniger als drei Jahren” auf dem Markt sei. Garnier würde es nach eigenen Worten nicht schrecken, wenn der Wettbewerber Merck & Co. mit dem Produkt schneller auf den Markt käme als Glaxo. „Der Bedarf wird so groß, da schadet es nicht, wenn es zwei Anbieter gibt”, sagt Garnier. Tatsächlich hat Merck & Co. beziehungsweise das Gemeinschaftsunternehmen Sanofi Pasteur MSD, an dem Merck & Co. und der französische Sanofi-Aventis-Konzern zu gleichen Teilen beteiligt sind, bei der europäischen Arzneimittel-Zulassungsbehörde Emea schon im Dezember den Zulassungsantrag für seinen Impfstoff Gardasil eingereicht, der dem von Glaxo in der Wirkung grundsätzlich vergleichbar ist, auch wenn die Unternehmen gegenüber der Fachöffentlichkeit graduelle Unterschiede herausstellen.


Schneller als der Virus: Forscher zielen auf junge Mädchen
Aus deutscher Sicht ist der zu erwartende Markterfolg der ausländischen Pharmakonzerne angesichts der Saat aus der hiesigen Grundlagenforschung nicht ganz ohne bitteren Beigeschmack. "Deutschen Unternehmen haben wir das lange vergeblich angeboten", hat Otmar Wiestler, der Leiter des DKFZ, schon beklagt. Andererseits gibt es nur noch wenige große Impfstoffhersteller auf der Welt - und Sanofi Pasteur MSD hat immerhin noch Wurzeln, die sich bis zur alten Frankfurter Hoechst AG zurückverfolgen lassen.

Für Mädchen im Alter von 10 bis 15

Grundsätzlich geht es bei der Impfung um den Schutz vor dem sogenannten Humanen Papillomvirus (HPV). Da die Viren in erster Linie durch sexuelle Aktivitäten übertragen werden, gilt es als sinnvoll, Mädchen im Alter zwischen zehn und fünfzehn Jahren zu impfen. Einige Forscher regen inzwischen an, die Impfung sogar noch früher vorzunehmen, so lange nämlich, wie die Betroffenen den Arzt ohnehin noch im Rahmen ihres normalen Impfzyklus aufsuchten, um die umfassende Versorgung sicherzustellen. Sicher ist, daß der Impfstoff gegen die Erreger nichts mehr ausrichten kann, wenn sie sich nach dem ersten Geschlechtsverkehr erst einmal in den Zellen des Gebärmutterhalses eingenistet haben.

Die Impfung schützt gegen die gefährlichsten Virenstämme 16 und 18 sowie im Fall von Merck & Co. wohl auch gegen HPV 6 und HPV 11, die vor allem Genitalwarzen verursachen. 70 Prozent aller sexuell aktiven Menschen werden einmal in ihrem Leben mit HPV infiziert, bei einem Teil von ihnen kommt es zu einer chronischen Infektion. Bei Frauen kann das zu Gebärmutterhalskrebs führen. Die meisten der rund zweihundert Virustypen sind für Menschen völlig harmlos. Das gilt allerdings nicht für die Typen 6, 11, 16 und 18. „Man weiß heute, daß mehr als 99 Prozent aller Gebärmutterhalskarzinome von HP-Viren verursacht werden”, sagt Torsten Strohmeyer, Leiter der Abteilung Forschung und Medizin bei Glaxo Smith Kline. In 70 bis 80 Prozent der Fälle seien es die Typen 16 oder 18 - und genau gegen diese Typen sei der von GSK entwickelte Impfstoff vollständig wirksam. Noch ist unklar, wie lange der für jeweils rund 800 Millionen Euro entwickelte Impfschutz anhält. Da die frühesten Patientenstudien erst vor gut sechs Jahren angelaufen sind, wird es noch einige Zeit dauern, bis man hierüber Klarheit erhält.

UCLA Researchers Identify How Antibody Blocks Prostate Cancer Growth In Animal Models
Researchers at UCLA's Jonsson Cancer Center have uncovered the mechanism by which an antibody blocks the growth of prostate cancer in animal models, a discovery that could pave the way for development of a new molecularly targeted therapy.

The antibody, called 1G8 and discovered by UCLA scientists, signals the prostate cancer cells to stop growing and die, said Dr. Robert E. Reiter, a Jonsson Cancer Center researcher and professor of urology. The antibody proved effective in several different animal models of prostate cancer, Reiter said, indicating that is could be a potent cancer fighter.

The research appears in the Oct. 15 issue of Cancer Research, a peer-reviewed journal published by the American Association for Cancer Research.

The 1G8 antibody binds to prostate stem cell antigen or PSCA, a cell surface protein discovered by Reiter that is found in about 95 percent of early stage prostate cancers and about 87 percent of prostate cancers that have spread to the bones. PSCA also is found in bladder and pancreatic cancers, Reiter and his team previously discovered, so a new targeted therapy developed from the antibody may also prove effective in battling those cancers.

"The big question with antibodies has been, how do they work?" said Reiter, senior author of the study. "Do antibodies recruit the immune system to kill the cancer or do they send a signal that tells the cancer cells to stop growing? This study shows how the antibody works, so we'll know how to apply it in the clinical setting."

The 1G8 antibody has two parts, one that binds with PSCA and one that binds with macrophages, the immune system's killer cells. Reiter and his team fragmented the antibody, separating the part that binds to PSCA and testing it alone in the animal models to see how it affected the prostate cancer cells. Even without engaging an immune response, the antibody blocked the growth of the prostate cancer cells.

"The fragments we created were unable to bind to the immune system, but they retained the same activity the whole antibody showed, so we proved that 1G8 must work by signaling the cancer cells to stop growing and die," Reiter said. "That's important because it provides a lot more information about what PSCA does and how antibodies work. It also suggests that PSCA is a very good target for therapy and that our antibody, in particular, is extremely active and binds to a region on the cell surface protein that may be an optimal target for a new treatment."

Molecularly targeted therapies are the new wave of cancer therapy, homing in on what is broken or mutated in the cancer cells and leaving the healthy cells alone. Because they only target the cancer cells, these therapies typically cause few side effects, if any, and are much easier for patients to tolerate.

The next step, Reiter said, is to test the 1G8 antibody in human clinical trials, probably in about a year.

This study is the result of years of laboratory research and is part of the Jonsson Cancer Center's Specialized Program of Research Excellence in prostate cancer, a National Cancer Institute-funded program to discover new and better ways to prevent, detect and treat prostate cancer.

"This work from start to finish is a UCLA discovery, true translational research that will go from the lab bench to the patient bedside," Reiter said.

Prostate cancer will strike more than 232,000 men in the United States this year alone, killing more than 30,350. Prostate cancer is the second leading cause of cancer death in men, according to the American Cancer Society.

UCLA's Jonsson Comprehensive Cancer Center comprises more than 240 researchers and clinicians engaged in cancer research, prevention, detection, control, treatment and education. One of the nation's largest comprehensive cancer centers, the Jonsson Cancer Center is dedicated to promoting research and translating the results into leading-edge clinical studies. In July 2005, the Jonsson Cancer Center was named the best cancer center in the western United States by U.S. News & World Report, a ranking it has held for six consecutive years.

Flu Frenzy Frames Biotechs' Futures

With the avian flu hysteria spreading exponentially faster than the disease itself, investors have been stocking up on Gilead Sciences (GILD:Nasdaq - commentary - research - Cramer's Take), the maker of the influenza drug Tamiflu -- the product that appears to offer the best hope against the virus.

Since the start of the year, Gilead's shares are up 49% compared with the 23% increase of the Amex Biotech Index and the almost 2% rise of the S&P 500. The company's market capitalization above $24 billion makes it one of the world's biggest biotechs.

5. Stern Stocks Up on Sirius





Recently the company has squabbled with marketing partner Roche over the rights for Tamiflu, but it remains at the forefront of any discussion about how best to prepare and protect against the bird flu.

There's little doubt that Gilead has a leading position in this fight, but rather quietly, lesser-known and often very small companies like Biocryst Pharmaceuticals (BCRX:Nasdaq - commentary - research - Cramer's Take) and AVI BioPharma (AVII:Nasdaq - commentary - research - Cramer's Take) are stepping up their own attempts at easing spreading fears of a pandemic.

The avian flu, primarily the H5N1 strain transferred from bird to bird, has been detected in more than 100 humans since the first reported bird-to-human case in Hong Kong in 1997. What's been garnering the most attention lately are worries that a mutant human-to-human version could be on the horizon.

Now that the disease has leaked westward, with cases showing up in Romania and Turkey, biotech companies are scrambling to develop their own vaccines and treatments for the disease.

Treatment Rush
Unlike vaccines, which are given as a preventative measure, antiviral drugs are meant for people already exposed to the virus. The goal with this type of treatment is to kill the invading bug before it spreads.

Besides Tamiflu, only one currently approved antiviral flu drug has been shown to work against the avian flu, Relenza from Australia's Biota. Relenza is marketed by drug giant GlaxoSmithKline (GSK:NYSE - commentary - research - Cramer's Take).

On Friday, Biota said it would support the French government's plan to build its Relenza stockpile to 9 million doses in the next two years, but there are concerns about just how much of the drug can be produced. After all, the proposed stockpile equals three times the drug's total sales since its launch in 1999, and Biota is suing GlaxoSmithKline, alleging that the company hasn't adequately supported Relenza.

Among proposed new antivirals, Biocryst Pharmaceuticals' Peramivir is on its way to clinical trials with support from the National Institutes of Health.

Peramivir, originally co-developed with Johnson & Johnson (JNJ:NYSE - commentary - research - Cramer's Take), was shown to stop the replication of the avian flu in lab mice in 2001. However, late-stage studies fell short of their goals and the partnership dissolved, with J&J saying it needed to focus its resources on higher-priority drugs.

Biocryst has said safety wasn't a factor in the pact falling apart, and investor hopes are running high that Peramivir might have a future after all. Biocryst shares have tripled in recent months to $11.30 from a 52-week low of $3.68.

Another antiviral drug developer, AVI BioPharma, is targeting several strains of the avian flu, as well as the common flu. AVI says its drug kills viruses by targeting a specific chunk of genetic code common in several types of influenza and that are critical to virus survival. The drugs were effective in early studies, and could enter animal studies as early as the end of the year, AVI Chief Executive Denis Burger said in an interview.

AVI, though small with a market cap around $160 million, has seen its shares run up 66% from the beginning of September, closing Monday at $3.69.

Protective Approach
Elsewhere, Novavax (NVAX:Nasdaq - commentary - research - Cramer's Take), which has a $130 million market cap, said it's focusing its resources to develop its own bird flu vaccine. Earlier this month, the company contended that it has a "compelling solution" to a pandemic and can produce large quantities of vaccine in a short period of time.

The company says a planned secondary stock offering will help fund the production, and New Jersey-based firm Wave Biotech will manufacture it.

Another tiny firm, Generex Biotechnology (GNBT:Nasdaq - commentary - research - Cramer's Take) (market cap $44 million) is looking to co-develop its avian influenza vaccine in China, and has proposed partnerships with the Harbin Veterinary Research Institute, Sinovac Biotech and Shanghai Institutes for Biological Sciences.

Of course, Gilead's Tamiflu has easily received the most attention. Tamiflu has been proven effective in treating the avian flu in humans, and it's already approved by the Food and Drug Administration to treat common strains of influenza. But Gilead says Roche has failed to adequately market Tamiflu, and the companies are involved in arbitration to decide the rights to the drug.

Roche has the sole marketing rights to the drug Gilead developed. Where it could get worrisome for these two companies, from an investment standpoint at least, is the fact that Taiwanese researchers and Indian generic drug company Cipla claim to have copied the drug. Cipla has said it plans to manufacture it, despite a possible court showdown with Roche.





1. Rumor Mill Turns to Juniper

Initially, Roche had refused to allow another company to manufacture Tamiflu, but that's changed amid growing worry and pressure from various regulators. Roche now says it's in discussions with eight companies, including large generic-drug makers, along with the governments of Taiwan and Vietnam.

Roche estimates it will have the capacity to produce 300 million doses of Tamiflu a year by 2006, or 10 times its 2004 capacity. The company expects to select potential partners for more detailed production discussions by the end of this month.

SPECIAL REPORT

Crossing The Gene Barrier
On the frontiers of biotech, two scientists are mingling the genetic materials of man and beast in new ways. The hoped-for outcome: Radical treatments for some of mankind's most intractable ailments


Slide Show >>Goats throughout history have been symbols of vitality and cunning, and treasured for their silky fur and nutrient-rich milk. But Sweetheart, a brown-striped goat with soulful eyes, has a secret that could elevate her far above this illustrious legacy. Named for her laid-back disposition, she has a single human gene in the twined strands of her DNA that enables her to produce a life-saving drug in her milk. It's a protein that's normally found in human blood.

In ancient times, the Greeks revered the god Pan -- part-man, part-goat -- who defended Athens against the Persians. Today, the dash of humanity imbedded in Sweetheart and 59 other goats at a central Massachusetts farm could provide a different but equally vital line of defense. Some people don't make enough of the protein in their livers, explains Harry M. Meade, the chief scientist at the company that created her. That raises the risk they'll suffer fatal blood clots during surgery. Others, such as burn victims and heart surgery patients, need a bit more of the protein to speed their recovery. If regulators in Europe approve Sweetheart's elixir in February, as expected, it's likely to be the first drug on the market derived from the milk of a part-human "chimera" -- a creature that bears the cells of two or more species.

A Tale of Two Scientists
Three thousand miles away, scientist Nils Lonberg reaches into a cage and scoops up a different sort of chimera. It looks like a subway-variety mouse, but its tiny body cradles a partial replica of one of the most intricate systems known to biology: a human immune system. This whiskered fur ball has the extraordinary ability to produce disease-fighting antibodies in its cells that can be harvested and turned into drugs. As the creature sniffs the hand of the scientist that invented her, the 49-year-old Lonberg responds as if he is encountering the animal for the first time. "I find this amazing," he says. The challenge of engineering this rodent is comparable to building a towering skyscraper, he says: "It's amazing that people can create something of this complexity."

This is the story of two scientists, Meade and Lonberg, who are toiling on the fringes of biotechnology. Their paths crossed 20 years ago, setting them on a quest to alter the age-old partnership between man and beast by mixing genes to concoct new medicines. Since then the two have pursued their goal on separate but parallel tracks. Meade, 59, is now chief scientific officer of Framingham (Mass.)-based GTC Biotherapeutics (GTCB ), which created Sweetheart. Lonberg is scientific director at Medarex Inc. (MEDX ), which is taking a lead in commercializing transgenic mice.

In the business of biotech, chimeras are about as close to science fiction as you can get. People have been crossing critters for centuries -- yielding everything from mules to labradoodles. But jumping the gene barrier by giving animals copies of human genes is more sensational. These creatures look, act, and smell like animals, yet their cellular machinery conceals unique biochemical capabilities. Already, 50 biotech and pharmaceutical companies are using mice from Medarex to develop treatments for terrible diseases -- from malignant melanoma to lymphoma to lupus. And GTC's goats may become factories for drugs that are too complex to produce any other way.

Yet as promising as these developments are, Meade and Lonberg strive to hold their optimism in check. Both spent years confronting the skepticism of other scientists, and even derision. Today, GTC and Medarex are burning through cash and investors are getting impatient. Other transgenics companies have shriveled and died. As drug regulators start issuing their rulings in coming months, the two men will learn whether their life's work will enrich mankind's supply of drugs or if their companies will sink into oblivion like so many other promising biotechs.

The saga of the goat and the mouse began in 1984, in a lab at Biogen Inc. in Cambridge, Mass. Meade and Lonberg were brainstorming how to manufacture a human protein that looked promising as a treatment for blood clots. They pulled an all-nighter devising a scheme for slipping human genes into the DNA of animals and then milking them to harvest the drug. The pair thought it was a brilliant idea, but few of their colleagues agreed. When Lonberg described it the next day to then-CEO Walter Gilbert and his management team, they nearly laughed the young scientist out of the room. "Gilbert looked at me and said, 'how about making it in goose eggs? You could have the goose who laid the golden egg,"' recalls Lonberg.

In fact, Meade points out, companies are now trying to do exactly that -- extract drugs from transgenic chicken eggs. "It sounds incredibly simple," Meade says, "but everything's in the details."

When Meade and Lonberg first began to tackle those details, they found themselves cast in the role of mad scientists. Having left Biogen in 1985, Lonberg was studying transgenics at Memorial Sloan-Kettering Cancer Center in New York. With the help of Meade, who often visited the lab, he succeeded in rejiggering the DNA of mice so they could produce human proteins in their milk. The scientists then rented a woman's breast pump from a pharmacy in New York and rigged it up to fit their tiny research subjects. "I remember them using this pipetting apparatus and applying it to the mouse nipples," laughs Elizabeth Lacy, Lonberg's former adviser at the cancer center. When Meade tried to return the borrowed breast pump a year later, the pharmacist was so shocked to hear what it had been used for that he refused to take it back.

Meade and Lonberg seemed like biotech's version of the Odd Couple. Meade, a jock who sometimes bikes 26 miles to work, once attracted a crowd at Biogen by demonstrating the moves he had learned in a break-dancing class. He wore his bike helmet to protect his head as he spun on the floor. The display startled Lonberg, who once ditched a required physical education credit at Reed College. It cost him his bachelor's degree, but it was a satisfying "act of defiance," Lonberg says. Having already been admitted to Harvard's PhD program in molecular biology, Lonberg called the head of the department to make sure the missing degree wouldn't matter.

Differences aside, Meade and Lonberg played off each other's strengths. Meade, the elder, passed on his knowledge of biochemistry and genetics to the young student. And as Lonberg focused his postgraduate studies on the then-embryonic field of transgenics, he taught Meade the intricacies of stitching human genes into animals. Together they co-authored the first issued patent on extracting drugs from milk in 1989.

Contemplating the gallons of milk necessary to make a drug, Meade planned to apply the technology to cows. Having grown up on a dairy farm outside Pittsburgh, he knew his research subject intimately. When the young Meade didn't have his nose buried in a science textbook, he was milking the family's herd and hanging out with the 4-H Club and the Future Farmers of America. "I was probably the only person who figured out butterfat content using a slide rule," Meade jokes.

At Biogen, Meade wasn't always confident that his bosses supported his plan to marry biotech with bovines. During analyst meetings, he recalls, "I had this feeling they were trotting me out for comic relief." He didn't feel truly in his element until he was managing research at GTC, a company devoted mostly to goat/human chimeras.

The Dolly Difference
In principal, giving Sweetheart and the rest of her herd the machinery to make human proteins is basic college biology. It's a matter of inserting a copy of a single human gene into her DNA and programming it to turn on in her mammary gland. But in the early days, GTC's method for tweaking the goat's DNA was so clumsy that only 5% of the kids were born carrying the human gene. Over the years, a string of scientific breakthroughs enhanced the process. Topping the list was the sheep called Dolly. After the Roslin Institute in Scotland cloned the now-famous sheep, GTC adapted the technology to its newest breeds of drugmaking goats -- boosting the success rate to nearly 100%.

Investors at first went wild over GTC's goats. In the late 1990s demand for biotech drugs was skyrocketing, and drugmakers faced a dire manufacturing crunch. GTC promised virtually unlimited capacity at a fraction of the $500 million it costs to build the typical biotech factory. It made perfect sense: You need more drugs? Breed more goats. Even some majors like Bristol-Myers Squibb (BMY ) and Johnson & Johnson (JNJ ) began talking with GTC. Investors piled in, pumping GTC's stock up to $50, which gave the unprofitable biotech a market value of more than $1 billion.

This wasn't sustainable. Drugmakers gradually improved the traditional way of making biotech proteins -- in cells housed in giant steel vats. Fears of a biotech manufacturing shortage subsided, and one by one, GTC's deep-pocketed partners pulled out. Investors bailed, too, driving GTC's stock down to single-digit territory. "You don't get many swings at the bat in this business," Meade says. "People lost faith."

But Meade himself remained steadfast. He was certain that his goats could correct a major shortcoming of steel vats -- the latter are terrible at churning out complex proteins. Sweetheart's protein, called antithrombin, is one such molecule. And to this day it can only be harvested from donated human blood, which is often in short supply. So, armed with $75.7 million from a stock offering GTC pulled off during the 2000 market boom, the company charged ahead on its own. Executives at GTC's former parent Genzyme Corp. (GENZ ) were impressed that Meade and his team never seemed to get discouraged. "There were enormous challenges. Some people thought they were crazy," says James A. Geraghty, senior vice-president at Genzyme, which still owns 9.6% of GTC's stock. "But crazy is not that different from passionate."

For Meade's old partner, Lonberg, passion has always come in a small package: mice. As a boy, in Arlington, Va., he took two gerbils his grandmother gave him and bred them into a colony of 56. And Lonberg met his scientist wife in a lab at Sloan-Kettering. "We literally met in a mouse house," he says. He remembers the two of them attending a transgenics conference in 1989, where a scientist announced a new technique for knocking out certain genes in mice in order to make them more like people. "Everyone got up and applauded," he says.

That same year, Lonberg joined a company with an ambitious plan to make mice more like men. Scientists in the early 1980s had already figured out how to produce human proteins in mice. But there was one snag: Resulting products would have bits of mouse protein in them, which would make people sick with side effects.

Ensconced at his new company, called GenPharm, he created and then bred two different varieties of gene-modified mice. One had a disabled immune system -- it couldn't produce any of its own antibodies. The other bore the genes that are responsible for making human antibodies. Immunologically speaking, the offspring of these two rodents is more human than rodent. Provoked by a disease-causing agent -- bits of a human tumor, for example -- "their cells produce antibodies in exactly the right form to go into humans," Lonberg says. The antibodies can then be mass-produced as drugs.

Triumph to Turmoil
What should have been a triumph led instead to a period of turmoil. After Lonberg trumpeted his mice at a 1993 conference, rival Cell Genesys (CEGE ) filed suit against GenPharm, claiming theft of trade secrets. GenPharm answered with claims of patent infringement. As the battle dragged on, chewing up the company's scarce capital, GenPharm was forced to pare down from 110 employees to seven. Still, amid general despair, Lonberg was determined to keep the technology alive. "We were so sad to see our good team falling apart," says former co-worker Frank Pieper. "One day Nils took us aside and spent a great deal of time explaining why GenPharm was right and how he was going to make sure we came out as winners." Three years later the parties settled. Cell Genesys (now called Abgenix (ABGX )) dropped the theft charge and paid GenPharm $40 million to cross-license its patents.

Once the legal hurdles were cleared, other biotechs started approaching Lonberg. One company that was particularly interested was Medarex, which like hundreds of other biotechs was pursuing antibodies, but without a distinctive technology that could quickly identify and generate the most promising molecules. "We needed a tool," recalls Donald L. Drakeman, CEO of Medarex. "Nils's transgenic mice gave us that." Medarex bought GenPharm in 1997 for $62.2 million in stock. Around this time, the stock market once again began to smile on biotech after a long slump. In March, 2000, Medarex made a smart move, just as GTC had done. It raised $388 million in a stock offering. "This changed Medarex," Lonberg says, by allowing it to build a research facility.

As if to remind Lonberg of his ongoing battle to conquer transgenics, a giant framed photo of a mouse stares down at the scientist in his Milpitas (Calif.) lab. Down the hall, more than 6,000 mice live in pathogen-proof rooms, hidden behind double doors. The scientists who wish to enter must first take showers and don cloth gowns from head to toe, to avoid passing along their germs to the valuable and pampered rodents.

But what if the protected mice were the ones that posed the threat? In Greek mythology, the chimera was a hybrid beast that breathed fire and foreshadowed natural disasters. Some experts take that as a metaphor. They worry that transplanted human genes -- particularly in farm animals -- could "leak" into the food supply, say, if a genetically modified critter were to run off and mate with a non-GM cousin. One of the last things you'd want is a bit of human protein -- one that could make healthy people sick -- turning up in the goat cheese that's sprinkled on top of your salad. Some people call this the "ick" factor. "Even when you have an ethical rationale for doing this work, people find it troubling," says Michigan State University philosophy professor Paul B. Thompson.

It would help if the regulations meant to prevent nightmarish accidents were actually enforced. Critics blast the Food & Drug Administration and U.S. Agriculture Dept. for failing to tighten regulations that will keep transgenic animals used in health care out of the food supply. Lobbying groups such as the Union of Concerned Scientists (UCS) were dismayed in 2002 when the University of Illinois at Urbana-Champaign sent 386 pigs used in transgenic experiments to slaughter. Only one animal had transgenes, but none of the pigs had been approved by the FDA for commercial use. (None ended up in the food supply.)

To avoid mistakes, GTC has rigorous security protocols. And the farm is hidden on a back road with no signs, to foil animal-rights vigilantes who might want to "liberate" the goats. GTC also designed nibble-proof pens, recognizing that goats have an uncanny ability to open latched doors with their teeth.

Even with such careful measures, there are questions that can't be corralled in electronic fences. As researchers amble further out on biology's frontier, they are forcing society to confront what it means to be human, and to consider whether scientists are changing that very definition by so freely mixing the genes of humans and beasts.

The pioneers of transgenics regard such metaphysical debates as random noise. They argue that a human being isn't defined by individual genes -- most of which are common to all animals. "DNA does not contain the soul or consciousness of a person," Meade declares.

For now, he and Lonberg are focusing on a more urgent matter: persuading regulators that their drugs are safe and effective. Their latest clinical-trial data are compelling, the scientists say, but now they are stuck in a waiting game. In September, European regulators said they needed more time to decide whether to approve goat-made antithrombin -- disappointing investors who had hoped for an October ruling. CEO Geoffrey F. Cox takes the delays in stride. "Making transgenic animals is very clever, but it's not a business," he says. "We've got work to do." If GTC succeeds, he says antithrombin could someday bring in more than $500 million in annual sales.

On a crisp October morning, the normally casual Meade arrives for work dressed in a suit. It's his turn to talk strategy with the board of directors. These days, the discussion is no longer confined to antithrombin. GTC has developed herds to produce other drugs, such as a malaria vaccine and a treatment to shrink solid tumors. Even though Meade is approaching the age when others might prefer golf courses to goat farms, he's too energized by the potential of transgenics to leave it behind. One day, he says, he'd like to make goats that can churn out treatments for infectious diseases such as HIV. "The first 20 years of my life I worked on a farm milking cows," Meade says. "The last 20 years I've spent trying to make [transgenics] work. It all kind of ties in."

As GTC inches toward approval of its first goat-made drug, other companies are showing interest in the technology. In July, Boston-based Merrimack Pharmaceuticals expanded a partnership with GTC, which has developed goats that produce Merrimack's experimental rheumatoid arthritis treatment. "We tried standard production technologies, but they didn't allow us to make it in a commercially viable way," says Robert Mulroy, CEO of Merrimack, who estimates that the drug will address a $4 billion market.

Medarex can also point to some progress. Of the 40 or so experimental drugs that have been derived from humanized mice, 27 come from Medarex' animals and the rest from rival Abgenix. In November, Abgenix announced that a cancer treatment developed with giant Amgen (AMGN ) shrank colon tumors 46% in a late-stage trial. A month later, Amgen scooped up Abgenix for $2.2 billion.

These developments also vindicate Medarex's work in humanized mice -- and it's own close partnership with Amgen. The biotech giant is developing three drugs using Medarex's mice. "It's a highly productive relationship and we anticipate doing further business with Medarex," says Scott Foraker, vice-president of licensing for Amgen. Will Amgen swallow Medarex, too? "We are continually evaluating acquisition and licensing opportunities," he says.

Last September, Pfizer Inc. (PFE ) took a stake in Medarex and paid $80 million up front for rights to as many as 50 antibodies over the next decade. The deal could ultimately bring Medarex $400 million. And Medarex and Bristol are co-developing a drug to treat metastatic melanoma. To remind himself how far he and his mice have come, Lonberg often pulls up before-and-after X-rays of a patient who received the drug. "He had 31 lung tumors. They're all gone," Lonberg says. The proof won't come until a pivotal, late-stage trial is completed next year, but Bristol is thinking about using the mice on more drugs.

Lonberg and Meade often catch up on the phone and at conferences. The two share a dream of making a drug together -- first generating a life-saving molecule in Lonberg's mice, then mass-producing it in Meade's goats. "Harry and I agree it would be a wonderful collaboration," Lonberg says. And a fitting epilogue to a 20-year history of transgenic beasts and human health care.

It is anticipated that, on a pro forma basis, cash, cash equivalents and securities available-for-sale for the combined Companies as of December 31, 2005 will be between $57 million and $60 million. The merger is intended to qualify for federal income tax purposes as a tax-free reorganization under the provisions of Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended. The merger agreement has been approved by both Boards of Directors and will need to be approved by each company's stockholders.

CancerVax expects to file a Form S-4 and related proxy statement/prospectus with the U.S. Securities and Exchange Commission and any other necessary government filings in the coming weeks. Depending on the review process of the agencies, the Companies would expect their respective stockholder votes to occur in the second quarter of 2006. Upon closing of the transaction, the Company's shares are expected to continue to trade on the NASDAQ National Market. CancerVax will be renamed as Micromet, Inc., and application will be made to NASDAQ to change the ticker symbol to "MITI." Piper Jaffray & Co. served as financial advisor and Latham and Watkins LLP as legal advisor to CancerVax. Cooley Godward LLP served as legal advisor to Micromet.

Management and Organization

Following the closing, the merged Company's U.S. headquarters will be in Carlsbad, CA, while the Company's German headquarters will remain in Munich, Germany. Research and development activities will be consolidated in Munich.

David F. Hale, currently President and Chief Executive Officer of CancerVax, will become Chairman of the Board of Directors of the merged company. Micromet's Chief Executive Officer, Christian Itin, will become President and CEO and serve on the Board of Directors. Patrick Baeuerle, currently Chief Scientific Officer of Micromet, will become CSO of the combined entity. CancerVax's Chief Financial Officer, William R.

The combined company's Board of Directors will consist of five current Micromet directors, including one director who is also currently a director of CancerVax, three other CancerVax directors and a ninth director to be named by Micromet prior to the merger.

Outlook for 2006

Following the merger, the Company plans to focus its resources on accelerating the development of its clinical-stage product development programs and leveraging its strong R&D base and pipeline-generating capabilities related to human antibodies, BiTE(TM) molecules and single-chain antibodies. The Company also plans to continue to build on Micromet's track record of successfully establishing drug development collaborations with major pharmaceutical companies, while retaining substantial commercial rights.

Anticipated milestones for the merged Company in 2006 include:

--  Closing the merger transaction in the second quarter;
--  Phase 2 clinical trial results for MT201 in patients with metastatic
   breast cancer and in patients with prostate cancer;
--  Phase 1 results for MT103 in the treatment of patients with NHL;
--  Filing of an investigational new drug application in the first quarter
   to initiate clinical trials with D93; and
--  Continuing to pursue partnering opportunities.
MT201 - Adecatumumab

Micromet's lead product candidate, MT201, is a recombinant human monoclonal antibody of the IgG1 subclass with a binding specificity to epithelial cell adhesion molecule (Ep-CAM). Ep-CAM is over-expressed with high frequency on most solid tumor types, including prostate, breast, colon, gastric, ovarian and lung cancer. MT201 is in Phase 2 clinical trials in patients with prostate cancer and metastatic breast cancer. In addition, MT201 is being evaluated as a combination therapy with Taxotere® (docetaxel) in a Phase I clinical trial in patients with metastatic breast cancer. The FDA has approved an investigational new drug application for MT201 for the treatment of patients with metastatic breast cancer.

In December 2004, Micromet announced an exclusive worldwide collaboration and license agreement with Serono, a Swiss corporation, for the development and commercialization of MT201. Micromet received an initial license fee of US$10 million and may receive additional milestone payments of up to US$138 million if the product is successfully developed and registered worldwide in three or more indications. In addition, Micromet may receive undisclosed royalties based on net sales of the product. Under certain terms and conditions, Micromet may elect to share in the development and commercialization of the product in the U.S. and E.U. in exchange for a share of profits.

MT103

Micromet's other leading product candidate, MT103, is being studied in a European Phase 1 clinical trial. MT103 represents a new class of therapeutics that may be capable of instructing the patients' own T cells (a very potent type of killer cell) to repeatedly eliminate tumor cells. This technology is called BiTE(TM) (bi-specific T cell engager). MT103 binds to CD19 on B cells, a cell surface antigen.

In June 2003, Micromet announced an agreement to jointly develop MT103 with MedImmune, Inc. Under the terms of the agreement, Micromet would receive milestone payments based on the successful development, filing, registration and marketing of MT103, as well as royalties on MedImmune's North American sales of the product. Micromet retained all rights to the product candidate outside of North America.

D93

CancerVax's D93 is a humanized, monoclonal antibody being studied for the treatment of solid tumors, which has been shown to selectively bind to denatured or remodeled protein in diseased or damaged tissues, but not to native collagen in the extra-cellular matrix of healthy tissue. D93 has demonstrated the ability to selectively bind to denatured collagen targets in colon, melanoma, lung, and breast cancer tumors grown in xenogeneic mouse models. The Company expects to submit an investigational new drug application for D93 to the FDA in the first quarter of 2006, and plans to initiate the first clinical trial for D93 later in 2006.

Micromet's BiTE(TM) Technology

Micromet's BiTE(TM) technology represents a novel therapeutic modality with the potential to develop antibody-based products to improve the treatment of diseases that currently lack satisfactory treatment options and that are resistant or refractory to standard therapies. BiTE(TM) molecules constitute a novel class of bi-specific antibodies that appear to be unique in their ability to activate the body's killer T cells against target cells. The proposed mechanism of action of Micromet's BiTE(TM) technology involves the activation of the available T cells in a patient's body, regardless of their specificity. This approach may have advantages, since in cancer therapy, patient-derived cancer tissue has to be recognized as "foreign" and eliminated by the patient's T cells. In many cases, tumors evade the recognition mechanisms used by T cells, in particular, and thus cannot be controlled by the patient's immune system. In summary, BiTE(TM) molecules are designed to provide each T cell with the ability to circumvent a number of tumor cell defense mechanisms.

Single-Chain Antibodies

Single-chain antibodies, which are used in the construction of BiTE(TM) product candidates, have demonstrated potential as therapeutics, diagnostics and as research tools. Single-chain antibodies comprise the antigen-binding site of antibodies engineered as a single protein. Under an agreement with Enzon Pharmaceuticals, Inc. Micromet is the exclusive licensor of the two companies' combined intellectual property estate in the field of single-chain antibody technology. Current licensees include Alexion Pharmaceuticals, Alligator Bioscience, Amersham Pharmacia, Arizeke Pharmaceuticals, Baxter Healthcare Corporation, BioInvent International AB, Bristol-Myers Squibb Company, Cambridge Antibody Technology, UCB Pharma, Crucell, EvoGenix, ESBATech, Invitrogen, MorphoSys, Merck & Co., Neoprobe Corporation and Xoma Corporation.

Conference Call Monday, January 9, at 9:00 AM Eastern Time / 03:00 PM Central European Time

CancerVax and Micromet will host a joint conference call on Monday, January 9, to discuss the planned merger and its business overview at 9:00 a.m. Eastern Time. A live audio webcast of management's presentation will be available at ir.cancervax.com.

Bird flu mutation sparks concern
Genetic tweak makes virus favour human nose and throat.
Declan Butler



© WHO

Researchers have sequenced the bird flu viruses that killed two people in Turkey in early January, and say that one of them contains a worrying mutation.

This genetic tweak can make the H5N1 virus more adapted to humans than to birds, and more adapted to the nose and throat than to the lungs. This latter effect could help to increase the chances of bird flu being transmitted between people, researchers say.

They add that many more mutations would probably be necessary before the virus is capable of sparking a full-blown pandemic, in which disease spreads like wild fire from person to person.

The samples of H5N1 virus, taken from the first two victims who died of bird flu in Turkey, were sequenced at a World Health Organisation (WHO) collaborating centre at the National Institute for Medical Research in London, UK. The results were announced on Thursday 12 January, along with confirmation of two new cases: bird flu has now also struck Sanliurfa Province, near Turkey's southern border with Syria, and Siirt Province, in the eastern part of Turkey.

The total number of reported human cases has now reached 18 in less than two weeks, three of which have been fatal.

In a bind

The WHO has released details of only one of the mutations found in the viruses. This genetic change results in a substitution of the amino acid serine by another amino acid, asparagine, at a specific position in one of the virus's proteins; a protein that helps the flu virus to bind to receptors on host cells.

This mutation has been observed twice before: in a father and son in Hong Kong in February 2003, and in one fatal case in Vietnam last year. It is known to increase the affinity of the virus for human receptors over poultry ones.

Until samples from the remaining cases are sequenced over the coming week, it is unknown how many of these came from viruses with the same mutation. If many prove to have the same tweak, this may help to account for the relatively large size of Turkey's rapid outbreak. The WHO's current explanation for the spate of cases is simply that people are bringing chickens into their homes during the harsh Turkish winter.

Nose and throat

The mutation also has a secondary effect, which may be more worrying.

There are two subtypes of receptors in the human respiratory tract: alpha 2.3, which occurs mainly in the lower respiratory tract; and alpha 2.6, which occurs mainly in the nose and throat. Human flu viruses typically show a preference for the 2.6 receptors, whereas H5N1 strains typically prefer 2.3.

This is good news for those worried about bird flu, since human-to-human transmission is thought to be more likely via droplets coughed from the nose and throat than from infections lower down. But the mutation found in the Turkey viruses is also known to be able to increase the affinity for H5N1 to the 2.6 receptors, points out Sylvie van der Werf, head of the Laboratory of Molecular Genetics of Respiratory Viruses at the Pasteur Institute in Paris, France.

Van der Werf adds that this affinity will, however, be affected by other genetic changes in the virus, which at present are an unknown factor.

Multiple mutations

Thankfully, one mutation alone is unlikely to lead to efficient human-to-human transmission. The genetic changes that would allow this to happen are poorly understood, but are thought to require an exact combination of changes in multiple genes.

"Adaptation to humans is a polygenic trait. It requires mutations in each of the eight segments of the virus's genome. Every one has to be correctly optimized to ensure human-to-human transmission," explains Edward Holmes, who is studying virus evolution at Pennsylvania State University in Philadelphia. "You are talking multiple mutations across the entire genome."

That's an improbable, but not impossible event.

Researchers continue to examine the genome of bird flu viruses, and are taking measures to stop the spread of disease among birds and people in Turkey.

A mutated strain of bird flu has genetic make up that increases its chance of transferring to people.

AVI BioPharma Reports Confirmation of Efficacy against Influenza Strains
Friday January 20, 9:00 am ET  
NEUGENE Antisense Efficacy against Influenza Strains, Including Avian Influenza, to Lead to IND Filing with the FDA


PORTLAND, Ore.--(BUSINESS WIRE)--Jan. 20, 2006--AVI BioPharma, Inc. (Nasdaq:AVII - News) today announced confirmation from three independent laboratories of NEUGENE® antisense efficacy in preclinical experiments against multiple strains of influenza, including avian influenza strain H5N1.
Dr. P. Puthavathana at Mahidol University in Bangkok, Thailand, confirmed NEUGENE antisense efficacy against an H5N1 viral isolate in her assay system.
Dr. Darwyn Kobasa at the Public Health Agency of Canada in Winnipeg, Manitoba, completed an initial dose-response study in cell culture demonstrating NEUGENE efficacy against both the H1N1 and H3N2 strains.
Dr. Manoj Pastey at Oregon State University in Corvallis, Ore., confirmed efficacy using the same NEUGENE antisense agents against the H7N7 and H3N8 strains.
Taken together, these data confirm efficacy observed with the H1N1 strain previously reported from Drs. Jianzhu and Chen Qin Ge at Massachusetts Institute of Technology in Boston and now represent positive reports from four laboratories using different endpoints and methodologies.

"These confirmations validate our approach to blocking replication of influenza viruses. We now believe that a single NEUGENE drug could be effective against most influenza subtypes, including the H5N1 avian strain," said Patrick L. Iversen, Ph.D., senior vice president of research and development at AVI. "By targeting regions of the viral genetic code that are common to all influenza A subtypes, we expect that our NEUGENE drugs will be effective against avian flu and the far more common influenza A viruses, which kill an average of 35,000 Americans every year."

AVI is also conducting collaborative animal studies evaluating NEUGENE efficacy against influenza strains at Tulane University in New Orleans and at the U.S. Army Medical Research Institute of Infectious Disease (USAMRIID) in Frederick, Maryland.

"Based on these recent findings and other results from additional studies, AVI now plans to file an Investigative New Drug (IND) application with the FDA for the treatment of influenza A virus with NEUGENE antisense drugs," said Denis R Burger, Ph.D., chief executive officer of AVI. "We feel confident in the safety, efficacy and potency of our NEUGENE drugs targeting influenza and plan to move forward into the clinical trial process later this year."

AVI's NEUGENE antisense drug development program against the influenza A virus specifically targets genetic regions of the virus that are highly conserved between six viral subtypes that cause human disease. These include three subtypes that caused pandemics in the 20th century -- the 1918 Spanish flu (H1N1), the 1957 Asian flu (H2N2) and the 1968 Hong Kong flu (H3N2) -- and three subtypes of avian flu that have been reported to cause disease in humans (H5N1, H7N7 and H9N2).

AVI's Antiviral Program

AVI's proprietary NEUGENE antisense drug candidates have demonstrated efficacy in preclinical studies against SARS coronavirus, West Nile virus (WNV), hepatitis C virus (HCV), dengue virus, Ebola virus, and Marburg virus. AVI has filed IND applications with the U.S. Food and Drug Administration and has ongoing clinical trials in WNV and HCV.

Showing how versatile NEUGENE drugs can be across viral subtypes, AVI demonstrated in its collaboration with the Centers for Disease Control and Prevention that NEUGENE agents are efficacious against all four immunologically distinct subtypes of the dengue virus. This outcome was achieved by targeting a highly conserved region of the dengue viral genetic code. In collaborative work with the USAMRIID targeting the Ebola virus, NEUGENE drugs protected three animal species from lethal challenges with this virus (see PloS Pathog 2(1): e1). Additional clinical development efforts targeting dengue virus and Ebola virus are planned for 2006.

The speed with which effective NEUGENE drugs can be designed and manufactured exceeds any other modern drug development timeframe. For example, NEUGENE compounds targeting SARS, WNV and Ebola were developed within days to weeks of obtaining the appropriate genetic sequences for the viruses.

AVI's Clinical Experience

AVI's NEUGENE antisense drugs have a well-defined safety record in human clinical trials. Approximately 300 patients have been dosed with NEUGENE drug candidates targeting host and viral gene targets in 12 clinical studies under multiple INDs. Five routes of administration have been employed in AVI's clinical studies, and doses up to 450 mg have been administered without a single drug-related, serious adverse event. The combination of AVI's NEUGENE chemistry with conserved viral targets that are not expressed in the human genome makes a strong case for the potential for success in the development of candidates to address influenza, including the possible emergence of a transmittable avian flu.

About Influenza A Viruses

Influenza, or flu, is a contagious respiratory illness caused by influenza viruses. On average 5 percent to 20 percent of the U.S. population is infected with the flu each year. Influenza A virus is an enveloped negative-strand RNA virus, with eight genome segments that code for 10 proteins. Influenza strains are subtyped according to the antigenic and genetic nature of their surface glycoproteins: hemagglutinin (HA or H) and neuraminidase (NA or N). Fifteen H and nine N subtypes have been identified, with three associated with widespread human disease (H1N1, H2N2 and H3N2). In addition, several subtypes of avian influenza virus -- H5N1, H7N7 and H9N2 -- can infect and cause disease in humans.

The current influenza pandemic in birds throughout Asia, Eastern Europe and Turkey is caused by the H5N1 subtype. It is thought that co-infection of humans or certain animals (such as pigs) with both H1N1 and H5N1 can lead to a reassortment or recombination of viral particles, resulting in the emergence of a virus with dangerous public health properties, namely one to which the human population has no natural immunity and which has the ability to spread easily from person to person. It is believed that emergence of avian flu by this general mechanism may have led to the worldwide pandemics of 1918, 1957 and 1968.

Die MorphoSys AG (Frankfurt: MOR; Prime Standard Segment; TecDAX) Anzeige
 
gab heute bekannt, dass ihr Partner Roche alle notwendigen Anträge für den Start einer europäischen Phase-1-Studie mit einem HuCAL®-basierten Antikörper zur Behandlung von Alzheimer eingereicht hat. Der HuCAL® Antikörper soll anormale, für Alzheimer-Patienten typische Ansammlungen des Proteins Amyloid-beta im Gehirngewebe, so genannte Plaques, angreifen und diese auflösen helfen. Der Antrag für den Beginn klinischer Studien löst eine Meilensteinzahlung von Roche an MorphoSys aus. Weitere finanzielle Einzelheiten wurden nicht bekannt gegeben. In präklinischen Studien hat der vollständig menschliche Antikörper eine hoch-affine Bindung an die Amyloid-beta-Plaques gezeigt und konnte diese spezifisch in menschlichen Gewebeproben von Alzheimer-Patienten erkennen. Darüber hinaus konnte in einem in-vitro-Test durch Bindung des Antikörpers an Amyloid-beta-Moleküle eine Ansammlung der Proteine aufgelöst werden. Der HuCAL® Antikörper wurde darüber hinaus in einem Tiermodell für die Untersuchung von Alzheimer eingesetzt. In die Blutbahn verabreicht konnte der Antikörper hier zeigen, dass er die Blut-Hirn-Schranke passieren und an Amyloid-beta-Plaques im Gehirn binden kann. Die internationale Alzheimer-Forschung sieht im Aufbrechen der Amyloid-beta-Ansammlungen einen viel versprechenden Ansatzpunkt für eine Therapie der Krankheit. Ein Entfernen der Plaques konnte mit einer Verbesserung der kognitiven Funktionen in Verbindung gebracht werden. "Wir sind sehr stolz, einen vollständig menschlichen Antikörper aus der HuCAL® Technologie von MorphoSys in die klinische Entwicklung bringen zu können. Dies ist ein wichtiger Schritt hin zu einer modernen Therapie von Alzheimer mit einer neuen Substanzklasse", sagte Andrew Sleight, Leiter der Forschungsabteilung Zentralnervensystem (ZNS) bei Roche. "Alzheimer ist sowohl eine verheerende Krankheit für die Betroffenen, als auch eine enorme finanzielle Belastung für die Gesundheitssysteme weltweit", erklärt Dr. Marlies Sproll, Forschungsvorstand der MorphoSys AG. "Der Antikörper aus unserer Kooperation mit Roche hat sich als sehr aussichtsreicher Kandidat in präklinischen Studien erwiesen und wir erwarten den Ausgang der Studien in menschlichen Patienten mit großem Interesse."

Cambridge Antibody Technology Group Says Arthritis Drug It Developed Achieves Blockbuster Status


NEW YORK (AP) -- Cambridge Antibody Technology Group PLC acknowledged Wednesday that the arthritis drug it developed has finally achieved blockbuster status in excess of previous estimates.
The Cambridge, England-based biotech company noted that Abbott Laboratories reported worldwide Humira sales of $1.4 billion, above the estimated $1.3 billion in sales. A blockbuster drug is one that has annual sales in excess of $1 billion. Humira is Cambridge's first marketed product. The company receives royalties of about 2.7 percent of Abbott's worldwide Humira sales. Abbott reported today that its 2005 revenue rose 14 percent to $22.34 billion from a year ago.

Cambridge Antibody also recognized that Abbott forecasts worldwide Humira sales of $1.9 billion in 2006.

The two companies reached a settlement in October over Humira royalty rates. Abbott agreed to pay Cambridge more than $300 million, but reduced the royalty rate to the present one from 5.1 percent.

Cambridge American depositary shares rose 37 cents, or 3.2 percent, to $11.98 in midday trading on the Nasdaq. Abbott shares added $2.58, or 6.4 percent, to $42.64 on the New York Stock Exchange.

GPC Biotech: 1D09C3 erhält Orphan-Drug-Status von EU-Kommission  

10:53 27.01.06  

Das biopharmazeutische Unternehmen GPC Biotech AG (ISIN DE0005851505/ WKN 585150) gab am Freitag bekannt, dass die Europäische Kommission dem monoklonalen Krebsantikörper 1D09C3 den so genannten Orphan-Drug-Status für die Anwendung bei chronischer lymphatischer Leukämie erteilt hat.

Der Orphan-Drug-Status der EMEA soll die Entwicklung solcher Medikamente fördern, die seltene lebensbedrohende oder äußerst ernste Leiden behandeln und die nicht mehr als fünf von 10.000 Personen in der EU betreffen. In der EU genießen Orphan Drugs in der ausgewiesenen Indikation Marktexklusivität von bis zu zehn Jahren. Andere mögliche Vorteile sind unter anderem: Gebührenminderungen im Zusammenhang mit verschiedenen Vorgängen des Zulassungsverfahrens, wie etwa beim Antrag auf Marktzulassung, sowie Unterstützung bei der Erstellung von Prüfplänen für die zulassungsrelevanten Studien.

1D09C3 ist ein Anti-MHC (Major Histocompatibility Complex) Klasse II monoklonaler Antikörper. Er bindet an spezifische Zelloberflächenrezeptoren und führt so zum gezielten Absterben aktivierter, sich vermehrender MHC-Klasse-II-positiver Tumorzellen, darunter B-Zell- und T-Zell-Lymphome sowie weitere Blutkrebsarten. In präklinischen Studien konnte gezeigt werden, dass 1D09C3 den programmierten Zelltod auslöst, ohne hierfür ein voll funktionsfähiges Immunsystem zu benötigen.

Der Krebsantikörper befindet sich derzeit in einem klinischen Phase-1-Studienprogramm, in welchem er bei Patienten getestet wird, die an einem resistenten B-Zell-Lymphom leiden oder nach einer zuvor durchgeführten Standardtherapie einen Rückfall erlitten haben. 1D09C3 wurde bereits für die Behandlung von Hodgkin-Lymphom der Orphan-Drug-Status zugesprochen.

Bisher stiegen die Aktien um 4,11 Prozent und schlossen bei 11,66 Euro.

New Study Supports Ep-CAM as Prime Target for Antibody Therapy in Common Cancers



Ep-CAM Is Frequently Expressed in Colon, Lung, Prostate and Gastric Cancers

February 3, 2006 – Munich, Germany – The University of Basel, Switzerland, and Micromet AG have published a new study on the frequent high-level expression of antibody target epithelial cell adhesion molecule (Ep-CAM) in colon, lung, prostate and gastric cancers. The report has been published in the British Journal of Cancer (2006, 94: 128 – 135) (1). Ep-CAM is the target for Micromet's human antibody adecatumumab (MT201), which currently is in two phase II clinical trials in prostate and metastatic breast cancer, and is partnered with Serono.

The immunohistochemical study analyzed Ep-CAM expression on tissue micro-array samples from more than 4,000 cancer patients. Patient samples were derived from primary tumor tissues covering all stages, grades and histologies of respective cancer indications. High-level Ep-CAM expression, i.e. an intense and homogenous staining of tumor cells was observed for 97.7% of colon, 63.9% of lung, 87.2% of prostate and 90.7% of gastric cancer patients.

"Through its scientific co-founder Gert Riethmuller of Munich University, Micromet has a long-standing expertise and interest in Ep-CAM as a target for antibody-based therapeutics. Our data strongly support the notion that Ep-CAM is a prime target for immunotherapy", comments Patrick Baeuerle, Micromet's Chief Scientific Officer. "Together with data published earlier on breast cancer, our study suggests that a large percentage of patients with colon, lung, prostate, gastric and breast cancer may qualify for treatment with Ep-CAM-directed antibody therapies, such as adecatumumab. Therefore, we expect that at least five of the most frequent human malignancies can potentially be addressed by our product candidate."

Recently published studies support that over expression of Ep-CAM plays a pivotal role in tumorigenesis. In human breast cancer, over expression of Ep-CAM is a negative and independent prognostic marker for overall survival (2), and Ep-CAM is expressed significantly higher on metastatic than on primary breast tumors (3). Proliferation, migration and invasiveness of tumor cells is inhibited when Ep-CAM expression in breast cancer cell lines is reduced by a specific small inhibitory RNA (4). When over expressed in quiescent cells, Ep-CAM behaves like a classical oncogene, enabling growth of cells in soft agar and independence on serum growth factors (5). Lastly, highly tumorigenic human breast cancer stem cells are characterized by expression of Ep-CAM (ESA) (6).

In January 2006, Micromet announced a definitive agreement to merge with CancerVax Corporation (NASDAQ: CNVX) to create a transatlantic, NASDAQ-listed company with a highly differentiated drug development pipeline focused on oncology, autoimmune and inflammatory diseases, and a proprietary technology base for the development of antibody-based product candidates. The merger is subject to a number of conditions and expected to close in the second quarter of 2006. Upon closing of the transaction, the Company's shares are expected to continue to trade on the NASDAQ National Market.  CancerVax will be renamed as Micromet, Inc., and application will be made to NASDAQ to change the ticker symbol to "MITI". CancerVax expects to file a Form S-4 and related proxy statement/prospectus with the U.S. Securities and Exchange Commission and any other necessary government filings in the coming weeks. ###

THOUSAND OAKS, Kalif. 3. April 2006 Amgen (Nasdaq:AMGN), das größte Biotechnologie-Unternehemen weltweit, gab heute Ergebnisse der Phase-3-Pivotalstudie bekannt, die zeigen, dass Panitumumab das progressfreie Überleben der Krankheit und die Krankheitskontrolle (Ansprechrate und Stillstand der Krankheit) wesentlich verbessert verglichen mit Patienten, die mit besten verfügbaren Therapien (Best Supportive Care, BSC) bei fortgeschrittenem Kolorektalkrebs behandelt wurden und bei denen die konventionelle Chemotherapie nicht angeschlagen hatte. Die Ergebnisse wurden bei einer klinischen Plenarsitzung bei der 97. Jahresversammlung der ANZEIGE

American Association for Cancer Research (Abstract #CP-1) präsentiert.
"Panitumumab reduzierte das Fortschreiten der Krankheit um etwa die Hälfte verglichen mit den mit den besten verfügbaren Therapien behandelten Patienten", sagte Marc Peeters, M.D., Ph.D., Koordinator der Digestive Oncology Unit im Universitätsklinikum Gent und einer der Versuchsleiter der Studie. "Darüber hinaus ergaben die Unterschiede bei der objektiven Ansprechrate und dem Verhältnis der Patienten mit einer Stabilisierung der Krankheit zwischen Panitumumab und der besten verfügbaren Therapie die signifikante Wirksamkeit dieses Wirkstoffs."

Bei dieser multinationalen, offenen Phase-3-Studie wurden 463 Patienten mit fortgeschrittenem Kolorektalkrebs, bei denen die konventionelle Chemotherapie einschließlich Oxaliplatin und Irinotecan nicht angeschlagen hatte, randomisiert und erhielten 6 mg/kg Panitumumab plus BSC (n=231) alle zwei Wochen oder nur BSC (n=232). Ein unabhängiger zentraler Radiologie-Prüfungsausschuss beurteilte den Krankheitsverlauf und das Schrumpfen der Tumoren.

Patienten, die alle zwei Wochen Panitumumab erhielten, wiesen eine 46%ige Verringerung des Tumorfortschritts gegenüber denen auf, die nur BSC erhielten (p weniger als 0.000 000 001). Eine verhältnismäßig höhere Anzahl von Patienten zeigte mit Panitumumab an allen planmäßigen Untersuchungszeitpunkten bis Woche 32 kein weiteres Fortschreiten der Krankheit bzw. überlebten bis Woche 32. Zum Beispiel lebten nach sechs Monaten (Woche 24) ungefähr viermal mehr Patienten, die mit Panitumumab behandelt wurden, ohne weiteres Fortschreiten der Krankheit (18 Prozent gegenüber fünf Prozent, die nur BSC erhielten).

Doppelt so viele Patienten, die mit Panitumumab behandelt wurden, lebten in der Woche 32 ohne weiteres Fortschreiten der Krankheit (10 Prozent gegenüber vier Prozent, die nur BSC erhielten).

Versuchsleiter berichteten auch, dass Panitumumab gegenüber BSC allein die Krankheitskontrolle wesentlich verbesserte (36 Prozent gegenüber 10 Prozent), wie anhand der Ansprechrate und des Stillstandes der Krankheit bemessen wurde. Die objektiv und unabhängig bewertete Ansprechrate betrug mit Panitumumab acht Prozent gegenüber null mit BSC allein und die durchschnittliche Dauer der Response betrug 17 Wochen. Die Rate bezüglich des Stillstandes der Krankheit betrug mit Panitumumab 28 Prozent gegenüber 10 Prozent mit BSC allein.

Rund 75 Prozent der Patienten, die mit den besten verfügbaren Therapien behandelt wurden, wurden in einen Cross-Over-Arm aufgenommen, wo sie Panitumumab nach Fortschreiten ihrer Krankheit erhielten (n = 174). Die Behandlung mit Panitumumab erwies sich auch bei Patienten, die von dem BSC-Arm wechselten, als klinisch vorteilhaft, trotz des Progresses der Krankheit. In diesen Patienten bewirkte die Behandlung mit Panitumumab eine partielle Response von 10% und eine Stabilisierung der Krankheit und komplette Response bei 32 Prozent.

Eine Zwischenanalyse des Gesamtüberlebens in den beiden Gruppen erbrachte ähnliche Ergebnisse. Die Rate (75 Prozent) und der Zeitpunkt (durchschnittlich nach 7 Wochen) des Crossover aus dem Arm, der nur BSC erhielt, zu einer Behandlung mit Panitumumab sowie die Antitumoraktivität, die nach dem Crossover festgestellt wurde, beeinträchtigte die Möglichkeit, einen Behandlungseffekt auf das Gesamtüberleben zu zeigen (Risikoverhältnis = 0,93).

Panitumumab verbesserte das progressfreie Überleben und die Responserate unabhängig von dem gemessenen Grad bzw. der Intensität der EGFr-Färbung. Die Verbesserungen des progressfreien Überlebens und der Krankheitskontrolle waren unabhängig vom Alter, Geschlecht, dem Ort des primären Tumors (Kolon oder Rektum) oder dem Performance-Status.

Prüfplangemäß erforderte die Gabe von Panitumumab keine Vormedikation oder Aufsättigungsdosis und die Inzidenz von Infusionsreaktionen (jeden Schweregrades) war niedrig (ein Prozent). Es gab keine Infusionsreaktionen 3. oder 4. Grades. Im Panitumumab-Arm gaben mehr Patienten toxische Hautreaktionen, Erschöpfung, Bauchschmerzen, Übelkeit und Durchfall an. Bei 38 Prozent der mit Panitumumab behandelten Patienten wurde eine Hypomagnesiämie beobachtet (drei Prozent 3./4. Grades). Es bildeten sich weder Human-Anti-Human-Antikörpern (HAHA) noch Antikörper gegen Panitumumab de novo. Bei Patienten mit Anti-Panitumumab -Antikörpern wurde kein Einfluss auf die Wirksamkeit, Sicherheit und Pharmakokinetik festgestellt.

Über Panitumumab

Bei Panitumumab handelt es sich um einen experimentellen vollständig humanen monoklonalen Antikörper, der gegen den Rezeptor des epidermalen Wachstumsfaktor (EGFr) gerichtet ist, ein Protein, das bei der Signalübertragung von Krebszellen eine wichtige Rolle spielt. Panitumumab, ein monoklonaler IgG2-Antikörper, bindet mit hoher Affinität an EGFr. Panitumumab wurde anhand der XenoMouse®-Technologie hergestellt, welche einen vollständig humanen monoklonalen Antikörper erzeugt, der kein Mausprotein enthält. Das Immunsystem des Körpers kann das in chimären und humanisierten Antikörpern vorhandene Mausprotein als fremd erkennen und eine Immunantwort in Form von Infusionsreaktionen, allergischen Reaktionen oder Anaphylaxien auslösen. Das Ziel der Entwicklung vollständig humaner monoklonaler Antikörper ist es, eine wirksame und hoch affine Therapie anzubieten, die das Risiko dieser Art von Immunantwort minimiert.

Panitumumab erhielt im Juli 2003 von der US-amerikanischen Food and Drug Administration (FDA) die Einstufung "Fast Track" als Indikation bei Patienten mit metastasierendem Kolorektalkarzinom, die auf Standardchemotherapien nicht ansprechen. In klinischen Studien wurde der Wirkstoff sowohl als Monotherapie als auch in Kombination mit anderen Wirkstoffen zur Behandlung verschiedener Krebsarten, beispielsweise Kolorektalkrebs, Lungenkrebs und Krebs im Kopf-/Halsbereich, untersucht.

Über den Rezeptor des epidermalen Wachstumsfaktors (EGFr)

EGFr ist normalerweise an der Regulierung des Wachstums vieler verschiedener Zellen im Körper beteiligt, kann aber auch das Wachstum von Krebszellen anregen. Tatsächlich brauchen viele Krebszellen Signale vom EGFr um zu überleben. Der Rezeptor sitzt auf der Oberfläche dieser Tumorzellen und wird aktiviert, wenn natürlicherweise im Körper vorkommende Proteine, beispielsweise der epidermale Wachstumsfaktor (EGF) oder der transformierende Wachstumsfaktor alpha (TGF-alpha), an ihn binden. Durch diese Bindung verändert sich die Form des EGFr, wodurch wiederum interne zelluläre Signale in Gang gesetzt werden, die das Wachstum der Tumorzelle anregen. Panitumumab bindet an den EGFr, wodurch die Bindung natürlicher Liganden wie EGF und TGF-alpha an den Rezeptor verhindert wird und die Signale, die andernfalls das Wachstum der Krebszelle stimulieren und ihr Überleben ermöglichen würden, blockiert werden.

Über Kolorektalkarzinom

Kolorektalkrebs ist die dritthäufigste Krebsart, die in den USA bei Männern und Frauen diagnostiziert wird. Die American Cancer Society schätzt, dass 2006 rund 106.680 neue Fälle von Kolonkrebs und 41.930 neue Fälle von Rektalkrebs diagnostiziert werden.

British Rethinking Rules After Ill-Fated Drug Trial
Sign In to E-Mail This Print Single Page Save  By ELISABETH ROSENTHAL,
International Herald Tribune
Published: April 8, 2006
In February, when Rob O. saw the text message from Parexel International pop up on his cellphone in London — "healthy males needed for a drug trial" for £2,000, about $3,500 — it seemed like a harmless opportunity to make some much-needed cash. Parexel, based in Waltham, Mass., contracts with drug makers to test new medicines.

Just weeks later, the previously healthy 31-year-old was in intensive care at London's Northwick Park Hospital — wires running directly into his heart and arteries, on dialysis, his immune system, liver, kidneys and lungs all failing — the victim of a drug trial gone disastrously bad.

One of six healthy young men to receive TGN1412, a novel type of immune stimulant that had never before been tried in humans, Rob O. took part in a study that is sending shock waves through the research world and causing regulators to rethink procedures for testing certain powerful new drugs.

Although tests of TGN1412 in monkeys showed no significant trouble, all six human subjects nearly died. One is still hospitalized and the others, though discharged, still have impaired immune systems, their future health uncertain.

On Wednesday, after releasing its interim report on the trial as well as previously confidential scientific documents that were part of the application for a trial permit, the British government announced it was convening an international panel of experts to "consider what necessary changes to clinical trials may be required" for such novel compounds.

The outcome "could potentially affect clinical trials regulation worldwide," the announcement said.

In statements this week, both Parexel and the drug's manufacturer, TeGenero, emphasized that they had complied with all regulatory requirements and conducted the trial according to the approved protocol. But they declined to answer questions e-mailed to them about the specifics of the science involved.

"The companies have worked according to strict standards applicable for such type of studies," said Kristin Kaufmann, a spokeswoman for TeGenero.

Within an hour of receiving the milky white drug in a Parexel research ward in the hospital on March 13, the volunteers were racked with chills, pain and nausea, said Rob O., who asked that his last name not be used, for fear that he might be hurt professionally. A doctor informed him he was "seriously ill."

"But no one's going to die?" Rob O. recalled saying, believing he was participating in a fairly standard trial of a painkiller for arthritis.

The chilling response: "Two of you might. Who's your next of kin?"

In fact, TGN1412 is anything but standard. The first product of TeGenero, a tiny German company with just 15 employees, TGN1412 belongs to a completely novel class of manufactured antibodies that researchers thought could revolutionize the treatment of leukemia and rheumatoid arthritis.

Now, TGN1412 seems poised to go down in medical history as a pharmaceutical lemon, its disastrous trial raising serious questions about whether patient safety is adequately protected in the lucrative race to get products to market.

The British Medicine and Healthcare Products Regulatory Agency, which approved the trial at Northwick Park, announced Wednesday that "the way the trial was run" had not contributed to patient injuries, according to its preliminary investigation. The men experienced cytokine release syndrome, which involves an outpouring of toxic molecules when the immune system's T cells are activated, the report said; it could not have been predicted from previous animal studies using the drug, the association, TeGenero and Parexel agree.

But British regulators took the highly unusual additional step of appointing an expert panel to explore whether more stringent safeguards should be required for testing new biological drugs like TGN1412 that manipulate the immune system.

Many experts say that because TGN1412's unique property is to turn on potent, immune system T cells, overriding normal regulatory mechanisms, the clinical trials were extraordinarily risky. "There was strong reason to be very cautious," said Dr. Michael Ehrenstein, of University College London, who studies the molecules that TGN1412 affects. "Many people would say this was a very high-risk strategy. I'd have to agree with that."

Michael Goodyear, a Canadian oncologist and medical ethicist, said that even if the trial was not illegal or unethical, the research protocol and conduct on the day of the trial raise "a number of big red flags."

The concerns Dr. Goodyear and lawyers for the subjects raised include these:

¶Rob O. began receiving the drug intravenously long after the first volunteer was already experiencing symptoms possibly serious enough to halt the trial. Standard practice for such trials is to use just one patient or to separate tests by many days.

¶The information submitted by TeGenero to British regulators mentioned that a cytokine burst "could occur" after TGN1412 infusion. But in their application, researchers deemed the reaction "not expected" on the basis of trials with a single animal species, and did not mention this risk to the recruits, Rob O. said.

¶On its Web site, Parexel says, "The only services that matter are the ones that speed your product through clinical development." The subjects point out that approvals for drug trials in Britain are quicker than in the United States and the liability for injuries is less.

¶Rob O. said the novelty of TGN1412 never came up in upbeat pretrial briefings, adding, "I had no idea it altered the immune system."

The first human trials are risky and ethically complicated. They are designed to determine whether a compound is safe, not to provide a benefit to the subject. Such human trials must be approved by national regulators as well as medical ethics boards, though standards vary somewhat among countries and even among different panels.

"Research is a social good — we need better treatments for leukemia and arthritis — but there are risks," said Dr. Ezekiel J. Emanuel, chief of bioethics at the United States National Institutes of Health. "Being a construction worker is very risky, and we pay people to do that. So why not this?"

Noting that the TGN1412 trial had been approved by two separate British regulatory bodies and that the medicine had been tested in animals, he said, "This is a terrible, tragic event but so far I don't see any clear ethical problems."

The trial subjects, who were to spend three days as hospital inpatients, were mostly immigrants, some of them students or unemployed.

"These were not people who were well off," said Martyn Day, of the London law firm Leigh Day & Company, which is representing four of the men. "They thought this was relatively risk free."

At the orientation meeting there was little time to read the 11-page consent form, Rob O. said, although they had a chance to take it home. Headaches and bruising were listed as potential side effects, as well as a severe allergy. But eating nuts or using new cosmetics could create similar reactions, the form said.

In fact, so-called monoclonal antibodies frequently produce severe generalized symptoms like aches and chills, though their use is justified by the enormous potential benefit. "At my hospital, we almost killed people the first few times we used Herceptin," said Dr. Goodyear, referring to the popular breast cancer drug, adding that he now pretreats patients with medicines to counter possible reactions.

Parexel applied to test TGN1412 in both England and Germany in December, receiving permission in England first, on Jan. 27. Many countries are streamlining review processes to attract biomedical research, a strategy that may have backfired here, Dr. Goodyear said.

It is not clear if independent immunologists reviewed the trial design, and neither Parexel nor TeGenero answered this question.

The trial began Monday, March 13, at 8 a.m., when the men began receiving TGN1412, each 10 minutes after the last. Within half an hour, the first patient had a headache and chills, said Ann Alexander, a London lawyer who is representing him. Nevertheless, doctors continued injecting new patients. About the time Rob O.'s infusion started, at 9:10 a.m., the first patient had passed out in an adjacent room, according to Ms. Alexander.

Before long, Rob O. said, he began to ache and shiver, feeling as if he had been "submerged in arctic ice." For the rest of the day, six previously healthy men moaned in uncontrollable pain, vomited and struggled for breath, Rob O. and other participants said. Though a dose of steroids temporarily blunted the symptoms, their vital signs steadily deteriorated, and they were transferred to the intensive care unit.

Two of them were placed on ventilators. Uniformed men wheeled in blood filtering machines, Rob O. recalled, to cleanse the blood of acid. Doctors told him that his immune cells were attacking his organs.

The patients' families were summoned to the hospital at 3 a.m.

In statements, Parexel and TeGenero called the reactions "unforeseen and unexpected," noting that doses hundreds of times more powerful had proved safe in animals.

The experimental application filed with British authorities — released this week in response to a Freedom of Information Act request — showed that the companies at least realized the possibility of a devastating immune-system reaction, and that animal studies showed some signs of immune overdrive.

Those worries were set aside when monkeys infused with TGN1412 had no problems. Although Parexel technicians continued to draw blood in the intensive care unit, the companies have not been willing to share the medical data or even meet with the participants and their lawyers, Mr. Day, the lawyer, said.

With his immune system now essentially disabled, Rob O. says he cannot work, or even take the subway, for fear of infection. His liver and kidney tests are still abnormal. Britain's National Health Service covers his doctor's bills, but he has to pay the $87 cab fare.

Under British law, Rob O. may be eligible only for $50,000 to $70,000 in compensation, said Mr. Day, unless he can demonstrate permanent harm. Anyway, tiny TeGenero took out only a $3.5 million insurance policy to cover the trial.

Lawyers for the subjects are hoping to arrange for financial compensation and full disclosure of medical information on the drug without having to go to court.

"I can't believe that nobody will pay and nobody will be punished," Rob O. said. "If I've lost 20 years of life because my liver packs in at 60 rather than 80, who will cover that?"

Herceptin in Europa bei HER2-positivem Brustkrebs im Frühstadium zugelassen
Mittwoch 24. Mai 2006, 07:35 Uhr

          §
LONDON, May 24 /PRNewswire/ --
- Lebensverlängerndes Medikament lässt Frauen mit aggressiver Form von
Brustkrebs in ganz Europa wieder hoffen

Roche gab heute bekannt, dass die Europäische Kommission Herceptin
(Trastuzumab) für Patientinnen mit HER2-positivem Brustkrebs im Frühstadium
im Anschluss an eine Operation und Standard-Chemotherapie zugelassen hat.
HER2-positiver Brustkrebs, der etwa 20 bis 30 Prozent [i] aller Frauen mit
Brustkrebs befällt, erfordert besondere und unmittelbare Aufmerksamkeit, da
die Tumoren schnell wachsen und eine gesteigerte Rezidivwahrscheinlichkeit besteht.

Die Zulassung basiert auf eindrucksvollen Ergebnissen aus der
internationalen HERA-Studie

(HERceptin Adjuvant), derzufolge die Verabreichung von Herceptin im
Anschluss an die Standard-Chemotherapie im Vergleich zur ausschliesslichen
Chemotherapie das Rückfallrisiko des Krebses um 46% reduziert. [ii]
Gleichermassen bemerkenswerte Vorteile wurden auch bei drei anderen grossen
globalen und US-amerikanischen Studien beobachtet. [iii]

"Es ist lobenswert, dass die Zulassung von Herceptin für Brustkrebs im
Frühstadium in Europa so erstaunlich rasch abgewickelt wurde", so der
Kommentar von William M. Burns, CEO der Pharmazeutischen Abteilung von Roche.
"Herceptin hat eindeutig bewiesen, dass es die besten langfristigen
Überlebenschancen bietet, wenn es möglichst zu Beginn des Krankheitsverlaufs
angewendet wird. Diese Entscheidung bedeutet wirklich gute Nachrichten für
Patienten und die medizinische Gemeinde. Wir werden jetzt mit den nationalen
Behörden zusammenarbeiten, damit den Ärzten und Patienten in ganz Europa
diese Behandlungsmethode garantiert zugänglich ist."

Herceptin war zuvor in der EU zur Behandlung von metastasiertem
(fortgeschrittenem) HER2-positiven Brustkrebs zugelassen worden. Diese neue
Genehmigung gestattet es nun Frauen in jedem Stadium dieser aggressiven
Krankheit, einschliesslich Brustkrebs im Frühstadium, diese
lebensverlängernde Behandlungsoption zu nutzen.

Die Beständigkeit der Ergebnisse aus vier grossen Versuchen mit über
12.000 Patientinnen hat medizinische und behördliche Organisationen auf der
ganzen Welt bewogen, schnelle Massnahmen zu ergreifen, damit Herceptin
Patientinnen mit HER2-positivem Brustkrebs im Frühstadium zur Verfügung
steht. Herceptin erhielt vor kurzem den Zulassungsstatus in Neuseeland und
Australien, und mehrere Länder haben im Lauf des letzten Jahres vor Erteilung
der Lizenz klinische Richtlinien entwickelt und Mittel bereitgestellt, um in
Frage kommenden Patienten einen schnelleren Zugang zu gewähren.

In den USA hat Genentech am 15. Februar 2006 bei der Food and Drug
Administration (FDA) einen zusätzlichen Antrag auf biologische Zulassung
(Biologic License Application = sBLA) zur Anwendung von Herceptin bei
HER2-positivem Brustkrebs im Frühstadium gestellt. Dieser Antrag basiert auf
Daten aus der kombinierten Zwischenanalyse von zwei grossen US-Versuchen
[iv], und Genentech hat einen vorrangigen Prüfungsstatus erreicht.

Informationen zur HERA-Studie

HERA, von Roche und der Breast International Group (BIG) durchgeführt
[v], ist eine der umfangreichsten adjuvanten Studien an
Brustkrebspatientinnen überhaupt; die Registrierung begann im Dezember 2001,
und es wurden beinahe 5.100 HER2-positive Patientinnen in 480
Untersuchungsstandorten in 39 Ländern weltweit aufgenommen. HERA ist ein
randomisierter Versuch im Anschluss an die herkömmliche systemische
Begleitchemotherapie und (gegebenenfalls) Strahlenbehandlung, bei dem
Beobachtung (also keine weitere Behandlung) versus Herceptin alle drei Wochen
für einen Zeitraum von 12 Monaten oder 24 Monaten bei Frauen mit
HER2-positivem Brustkrebs im Frühstadium bewertet wird. Die HERA-Studie liess
die Anwendung einer breiten Palette an chemotherapeutischen Verfahren zu, und
sowohl lymphknotenpositive wie auch lymphknotennegative Patientinnen wurden
zu dem Versuch zugelassen.

Gemäss den Ergebnissen der Zwischenauswertung wurde der primäre Endpunkt
der Wirksamkeit erreicht. Es wurde nachgewiesen, dass Patienten, die
Herceptin erhalten hatten, im 12-monatigen Arm der Studie eine statistisch
signifikante Verbesserung des krankheitsfreien Überlebens erfuhren (darunter
versteht man die Zeitspanne nach der Behandlung, während der keine
Krankheitsanzeichen auftreten). Bei einer medianen Nachbeobachtung von einem
Jahr hatte der sekundäre Endpunkt des Gesamtüberlebens noch keine
statistische Signifikanz erreicht. Es war allerdings eine eindeutige Tendenz
zur Verbesserung des Gesamtüberlebens zu beobachten, was durch längerfristige
Daten noch zu bestätigen sein wird.

Die Zwischenanalyse verglich Herceptin mit reiner Beobachtung und schloss
keine Gegenüberstellung der 12-monatigen mit der 24-monatigen
Behandlungsdauer ein. Der Versuch wird diesen Vergleich weiterhin bewerten,
die entsprechenden Daten werden im Verlauf der Studie zum gegebenen Zeitpunkt
verfügbar sein.

Die HERA-Studie untersteht einem externen Datenkontrollausschuss
(Independent Data Monitoring Committee = IDMC), der regelmässig die
Unbedenklichkeitsfaktoren der Studie überprüft. Bisher hat das IDMC bezüglich
der Sicherheit keine Bedenken geäussert, und das Auftreten von kongestiver
Herzinsuffizienz war geringfügig (0,5% beim Herceptin-Arm versus 0% beim
Beobachtungs-Arm). Die Patientinnen dieser Studie werden weiterhin auf
eventuelle Nebenwirkungen hin überwacht.

Informationen zu Brustkrebs und Herceptin

Acht bis neun Prozent aller Frauen erkranken im Lauf ihres Lebens an
Brustkrebs, was diesen zu einer der häufigsten Formen des Krebses bei Frauen
macht. [vi] Alljährlich werden weltweit über eine Million neuer Fälle von
Brustkrebs diagnostiziert, wobei die Sterberate bei fast 400.000 pro Jahr
liegt.

Beim HER2-positiven Brustkrebs befinden sich erhöhte Mengen des
HER2-Proteins an der Oberfläche der Krebszellen, was als 'HER2-positiv'
bezeichnet wird. Hohe Konzentrationen von HER2 sind bei einer besonders
aggressiven Form der Krankheit vorhanden, die nur schlecht auf Chemotherapie
anspricht. Untersuchungen haben ergeben, dass etwa 20 - 30 Prozent aller
Frauen mit Brustkrebs HER2-positiv sind.

Herceptin ist ein humanisierter Antikörper, der gezielt die Funktion von
HER2 blockieren soll. HER2 ist ein Protein, das von einem bestimmten Gen mit
krebsverursachendem Potenzial produziert wird. Abgesehen von der Wirksamkeit
bei Brustkrebs im Frühstadium hat Herceptin auch verbessertes Überleben im
fortgeschrittenen (metastasierten) Stadium unter Beweis gestellt, wo die
Kombination mit Chemotherapie im Vergleich zur Chemotherapie allein den
Patientinnen eine bis zu einem Drittel längere Überlebenszeit gewährt. [vii]

Herceptin wurde im Jahr 2000 in der Europäischen Union zur Anwendung bei
Patientinnen mit metastasiertem Brustkrebs zugelassen, deren Tumore einen
Überschuss des HER2-Proteins aufwiesen. Neben der Anwendung in Kombination
mit Docetaxel als Erstlinientherapie für HER2-positive Patienten, die keine
Chemotherapie für ihre metastasierte (fortgeschrittene) Krankheit erhalten
hatten, ist Herceptin auch als Erstlinientherapie in Kombination mit
Paclitaxel angezeigt, wenn Anthrazykline ungeeignet sind, sowie als
Monotherapeutikum bei der Drittlinientherapie. Herceptin wird in den
Vereinigten Staaten von Genentech, in Japan von Chugai und in den übrigen
Ländern von Roche vertrieben. Herceptin wurde seit 1998 zur Behandlung von
über 230.000 HER2-positiven Brustkrebspatientinnen weltweit eingesetzt.

MabThera gegen rheumatoide Arthritis EU

BASEL, Schweiz, June 3 /PRNewswire/ --


- Erstes selektiv auf die B-Zellen wirkendes Medikament bietet Patienten
eine wahre Alternative bei der Behandlung dieser beeinträchtigenden Krankheit



Roche gab heute bekannt, dass der Ausschuss für Humanarzneimittel (CHMP)
eine Zulassungsempfehlung für MabThera (Rituximab) zur Behandlung von
rheumatoider Arthritis (RA) in Europa erliess. Dies bringt MabThera, die
erste und einzige selektiv auf B-Zellen wirkende Therapie, einen Schritt
näher für RA-Patienten, die auf die gegenwärtigen Behandlungsoptionen
(einschliesslich TNF-Inhibitoren) ANZEIGE
 
mit einer unzureichenden Ansprechrate oder
Unverträglichkeit reagierten. Die B-Zellen spielen in der Entzündungskaskade,
welche letztlich zu den für rheumatoide Arthritis typischen Knochen- und
Knorpelschäden in den Gelenken führt, eine wichtige Rolle.



Professor Paul Emery, University of Leeds, GB, einer der leitenden
Prüfärzte in der REFLEX(1) Studie kommentierte: "Dies ist ein wichtiger
Moment - MabThera wird für die RA-Patienten in Europa, die durch die derzeit
verfügbaren Therapien keine ausreichende Linderung erfahren oder diese
Therapien nicht vertragen, erhebliche Vorteile bringen. Dieser neue Ansatz
verspricht mit jedem kurzen Behandlungszyklus alle 6 bis 12 Monate
nachhaltigen klinischen Nutzen."



"Die positive Stellungnahme des CHMP ist ein grosser Meilenstein für
MabThera - das erste Medikament für rheumatoide Arthritis in unserem
Produkteportfolio im Bereich der Autoimmunkrankheiten. Wir freuen uns, dass
MabThera bald vielen an dieser beeinträchtigenden Krankheit leidenden
Menschen als neue Behandlungsalternative zur Verfügung stehen wird," sagte
Eduard Holdener, Leiter von Pharma Development bei Roche.



Die positive Stellungnahme des CHMP gilt für MabThera in Kombination mit
Methotrexat zur Behandlung von erwachsenen Patienten mit schwerer aktiver
rheumatoider Arthritis (RA), die zuvor nicht ausreichend auf andere
krankheitsmodifizierenden Antirheumatika (einschliesslich eines oder mehrerer
Tumornekrosefaktor(TNF)-Inhibitoren) angesprochen oder diese Medikamente
nicht vertragen hatten. Bis zu 40 % der RA-Patienten, die mit derzeit
verfügbaren Biotherapeutika behandelt werden, sprechen nur ungenügend auf die
Behandlung an und haben wenig andere Behandlungsalternativen. Daher besteht
ein dringender Bedarf an neuen wirksamen Behandlungsoptionen für Patienten,
deren tägliches Leben durch diese schwerwiegende Krankheit beeinträchtigt
wird.



Die Bekanntmachung des CHMP kam nach den positiven Ergebnissen der
Phase-III-REFLEX-Studie, die zeigten, dass MabThera ein hochwirksames
Präparat zur Symptomlinderung bei RA-Patienten ist und eine nachhaltige
Verbesserung nach nur zwei Infusionen pro Behandlungszyklus bringt. Die
Studie zeigte insbesondere, dass MabThera beeindruckende Ergebnisse bei der
Reduzierung von Schwellungen und Schmerzen der Gelenke erzielte und somit die
Abgeschlagenheit und Lebensqualität der Patienten verbesserte. Eine
detaillierte Analyse der REFLEX-Studie einschliesslich der röntgenologischen
Daten über einen Zeitraum von einem Jahr sowie der Wirkung von wiederholten
Behandlungszyklen wird im Juni 2006 auf dem EULAR-Kongress (European League
Against Rheumatism) präsentiert.



MabThera wird in den USA von Genentech unter dem Namen Rituxan vertrieben
und erhielt vor kurzem nach einem beschleunigten Verfahren die Zulassung der
amerikanischen Gesundheitsbehörde FDA für die Behandlung von mittelschwerer
bis schwerer RA.



Die rheumatoide Arthritis stellt eine der häufigsten Autoimmunkrankheiten
dar und betrifft mit bis zu 2 Millionen Erkrankten allein in Europa mehr als
21 Millionen Menschen weltweit.



MabThera wird bereits als bewährte Behandlung von Non-Hodgkin-Lymphom
(NHL), einer Form von Lymphdrüsenkrebs, eingesetzt. Über 730.000 Patienten
wurden in den letzten 7 Jahren mit MabThera behandelt, ohne grösseren Anlass
zu Bedenken bezüglich der Sicherheit zu geben.



Über die REFLEX-Studie



Die REFLEX-Studie (Randomised Evaluation oF Long-term Efficacy of
Rituximab in RA) ist eine randomisierte, doppelblinde, placebokontrollierte
Phase-III-Studie an mehreren Zentren. Bei Patienten, die im Rahmen dieser
Studie einen einzigen Behandlungszyklus von nur zwei Infusionen MabThera in
Kombination mit einer gleich bleibenden Dosis Methotrexat (MTX) erhielten,
wurde nach 24 Wochen eine statistisch signifikante Besserung der Symptome im
Vergleich zur Patientengruppe mit Placebo plus MTX gemessen. Bei den meisten
Patienten, die weitere Behandlungszyklen erhielten, erfolgten diese jeweils
24 Wochen nach dem vorhergehenden Behandlungszyklus. Eine vorläufige Analyse
der REFLEX-Daten lieferten keine unerwarteten Erkenntnisse hinsichtlich der
Medikamentensicherheit. Die Unternehmen kontrollieren weiterhin die
langfristige Sicherheit von MabThera in allen klinischen Studien.



Signifikante Verbesserungen aller Symptomparameter



Die Ergebnisse der 6-Monatsanalyse zeigten, dass MabThera in Kombination
mit Methotrexat (MTX), einer Standardbehandlung von RA, hoch wirksam war und
verglichen mit MTX plus Placebo statistisch signifikant höhere Ansprechraten
erzielte: 51 % der Patienten verzeichneten eine 20-prozentige Verbesserung
der Anzeichen und Symptome (ACR20(2)), verglichen mit 18 % bei MTX allein.
Der Unterschied zwischen den beiden Gruppen war nach 8 Wochen ersichtlich und
wurde für die gesamte Dauer der Studie nach nur einem Behandlungszyklus von 2
Infusionen von MabThera im Abstand von 2 Wochen aufrechterhalten. Im Verlauf
der sechs Monate erzielten mehr als fünfmal so viel Patienten in der
MabThera-Gruppe eine 50-prozentige Verbesserung der Anzeichen und Symptome
verglichen mit MTX allein (ACR50: 27 % vs. 5 %), und zwölfmal so viele
MabThera-Patienten erzielten eine 70-prozentige Verbesserung (ACR70: 12 % vs.
1 %). Bei den meisten Patienten, die weitere Behandlungszyklen erhielten,
erfolgten diese 6 Wochen nach dem vorhergehenden Behandlungszyklus.



Über MabThera und rheumatoide Arthritis



MabThera zielt selektiv auf eine Untergruppe der B-Zellen ab, die CD20
exprimieren. Die Stamm-, Pro-B- und Plasmazellen bleiben dabei unangetastet.
Dieser Untergruppe der B-Zellen kommt im Autoimmunprozess bei rheumatoider
Arthritis eine zentrale Rolle zu; MabThera wirkt auf eine Unterbrechung
dieser Abfolge von Reaktionen hin, die zur Entzündung der Gelenkinnenhaut und
schliesslich zu dem für diese Krankheit typischen Knorpelschwund und
Knochenabbau führen. Mehr als 1000 Patienten mit RA wurden bisher in
klinischen Studien mit MabThera behandelt. Ein umfangreiches klinisches
Phase-III-Entwicklungsprogramm prüft derzeit den potenziellen klinischen
Nutzen von MabThera in früheren Stadien der rheumatoiden Arthritis näher.



Über rheumatoide Arthritis



Bei der rheumatoiden Arthritis handelt es sich um eine progressive
systemische Autoimmunkrankheit, bei der sich die Gelenkinnenhaut entzündet.
Diese Entzündung verursacht einen Verlust der Form und Funktion des Gelenks,
was zu Schmerzen, Steifigkeit und Schwellungen und schliesslich zu einer
irreversiblen Zerstörung des Gelenks und zu Behinderung führt. Zu den
typischen Symptomen der rheumatoiden Arthritis zählen Schwellungen, Schmerzen
und eingeschränkte Beweglichkeit der Gelenke an Händen, Füssen, Ellenbogen,
Knien und im Nacken. Rheumatoide Arthritis kann, wenn sie wichtige
Organsysteme beeinträchtigt, die Lebenserwartung verkürzen. Nach 10 Jahren
sind weniger als 50 % der Patienten noch in der Lage, einer Arbeit oder ihren
gewohnten Alltagsaktivitäten nachzugehen.

Neuer Trend: Signalkettenforschung

 
03.06.06 22:47

Hier geht es nicht um Antikörper sondern um einen neuen Ansatz des Pharmariesen Novartis. Artikel enthält auch einige interessante Aussagen zur Zukunftstrategie des Pharma-Konzerns.  


de.biz.yahoo.com/03062006/345/...zwingt-konzerne-umdenken.html

Samstag 3. Juni 2006, 21:15 Uhr


Die Zukunft von Novartis (Virt-X: NOVN.VX - Nachrichten) schwimmt zu Tausenden in kleinen Aquarien. Während man sonst in der Pharmaforschung auf die typischen Labormäuse zählt, sind in das neue Forschungszentrum des Schweizer Pharmakonzerns in Boston Zebrafische eingezogen.

Die durchsichtigen Organismen stehen seit zehn Jahren Modell für Grundlagenforscher, die verstehen wollen, wie sich komplexe Organe wie das Herz entwickeln. Novartis will mit ihnen in seinem Institute of Biomedical Research (NIBR) Wissen und Inspirationen Anzeige
 
für die Medikamenten-Entwicklung sammeln.

Ein großer, 1 Mrd. $ teurer Schritt in Richtung Grundlagenforschung - Terrain, auf das sich bisher meist nur Biotech (Brüssel: BIOT.BR - Nachrichten) -Unternehmen wagten.

"Die pure Ausrichtung auf angewandte Forschung, die man sich in den 80er und 90er Jahren leisten konnte, weil es genügend Therapieansätze gab, kann man sich heute nicht mehr leisten", sagt Jörg Reinhardt, einst Entwicklungschef von Novartis, heute Chef der von Novartis übernommenen Impfstofffirma Chiron. Während in den 90er Jahren jährlich Dutzende neuartige Medikamente auf den Markt kamen, waren es 2002 nur noch 17.

Immer häufiger genügen Neuentwicklungen den strengen Zulassungsstandards nicht. Ein "Produktivitätsloch", sagt Reinhardt. Gleichzeitig stiegen aber die Kosten von Entwicklung und Vermarktung auf bis zu 1,7 Mrd. $ pro Medikament. Und es sanken die Einnahmen: Die Verkaufsschlager der 90er verlieren den Patentschutz, bis zu 80 Prozent des Umsatzes gehen an Nachahmerpräparate verloren.Von Mäusen, Fischen und Fliegen"Die Pharmaforschung kann so nicht weitermachen", sagt Marc Fishman. Der Mediziner, der dem Zebrafisch zum Durchbruch verhalf, leitet die weltweite Forschung von Novartis in seinem Büro im NIBR. "Es gibt so viele Patienten, die wir noch immer nicht behandeln können. Die Medikamenten-Entwicklung ist einfach zu langsam."

Fishmans Vision für eine neue Pharmaforschung beruht auf Mäusen, Fischen, Fliegen und Hefezellen. Denn diese Arbeitstiere der biomedizinischen Forschung sind die Werkzeuge, das das Zusammenspiel der Gene in normalen und kranken Zellen verstehen und eventuell beeinflussen hilft.

So wissen Forscher inzwischen, dass grundlegende entwicklungsbiologische Mechanismen sich bei verschiedenen Organismen kaum unterscheiden. Die Evolution hat nicht nur einzelne Gene, sondern auch die Interaktionen zwischen ihnen, die so genannten Signalketten, jahrmillionenlang beibehalten.

Ein klassisches Beispiel ist die fast identische Signalkette, die sowohl beim Säugetier als auch bei der Fruchtfliege Drosophila die Augenentwicklung anstößt. Die Gene sind derart identisch, dass mit dem Gen der Maus der Ausfall des Fliegen-Pendants ersetzt werden kann. Und das Herz des Menschen wird von den gleichen Genen gebaut, die auch beim Zebrafisch aktiv sind.In der Zebrafisch-Arbeitsgruppe von Fabrizio Serluca am NIBR untersuchen die Forscher beispielsweise, welche Gene die Darmbewegungen der Fische kontrollieren. Diverse menschliche Erkrankungen hängen damit zusammen.

"Bei Mäusen lässt sich das schlecht untersuchen, aber der Zebrafisch ist durchsichtig, man kann direkt in den Darm sehen." Bestimmte Mutationen an Genen des Signalwegs lassen den Transport stocken. Diese neuralgischen Punkte will Novartis nutzen, um in die Regulation einzugreifen.

Dennoch sind die Zebrafische ungewöhnlich für Pharmafirmen, die so anwendungsferne Forschung in meist über Kooperationen mit Biotech-Unternehmen oder Universitäten regeln. Das ließ die Biotechbranche zunächst nervös werden, aus Angst, Kooperationen mit Novartis könnten wegbrechen.Den Signalweg erkennenAus den Novartis-Aktivitäten lasse sich kein allgemeiner Trend ableiten, meint Ralf Kindervater, Geschäftsführer des baden-württembergischen Biopro-Netzwerks: "Eine Trendwende zum kooperationsaversen Verhalten der Pharma-Unternehmen sehen wir nicht." Allerdings sind Firmen wie Novartis und auch GlaxoSmithKline (London: GSK.L - Nachrichten) mit ihren Forschungseinheiten auf die Grundlagenforscher zugegangen.

Die Biotech-Unternehmen müssen nun der Pharmabranche entgegenkommen. "Für Unternehmen, die mit ihren Entwicklungen den ,Proof of Concept‘ geliefert haben, stehen die Chancen gut", sagt Kindervater. "Wirkstoffe, für die eine Phase-IIb-Studie erfolgreich abgeschlossen wurde, sind interessant für Pharma."

Dass das Konzept "Mehr Forschung wagen" aufgehen kann, zeigt Novartis' Krebsmedikament Gleevec. Zwar taugt es nicht zum Kassenschlager, da es nur für etwa 30.000 Patienten im Jahr in Frage kommt. Doch Fishman zuckt nur mit den Schultern: "Wir werden Blockbuster-Signalketten haben, wodurch wir verschiedene Krankheiten ähnlich behandeln können."

Und auch Entwicklungschef Jörg Reinhardt ist sich sicher: "Das ist nur die erste Designermedizin, die wir durch unsere neue Forschungsstrategie, das Ziel und den Signalweg zu kennen, zu entdecken hoffen." Schon heute hat Novartis die Zahl neuer Wirkstoffe in der Pipeline mit 80 im Vergleich zu 1997 verdreifacht.

Montag 5. Juni 2006, 09:59 Uhr


Westerburg, 5. Juni 2006 (aktiencheck.de AG) - Der Pharmahersteller Schering AG (ISIN DE0007172009/ WKN 717200) und die amerikanische Genzyme Corp (NASDAQ: GENZ - Nachrichten) . (ISIN US3729171047/ WKN 871137) haben positive Forschungsergebnisse einer Phase III-Studie für das Medikament MabCampath vorgelegt.
Wie der Konzern am Samstag bekannt gab, hat die vorläufige Analyse des sekundären Studienendpunktes dieser Studie gezeigt, dass Patienten mit chronischer lymphatischer B-Zell-Leukämie (B-CLL), die den monoklonalen Antikörper MabCampath Anzeige
 
erhielten, signifikant höhere Ansprechraten (Gesamtansprechraten - ORR - und Raten der vollständigen Rückbildung der Krankheitssymptome - CRR) aufwiesen als Patienten, die mit Chlorambucil behandelt wurden. Im Rahmen der klinische Phase-III-Studie wurde MabCampath (Alemtuzumab) mit Chlorambucil verglichen.

In der offenen, randomisierten Studie mit 297 Patienten wurden Wirksamkeit und Sicherheit von MabCampath und Chlorambucil verglichen. Chlorambucil wird im Hinblick auf die Sicherheit für nicht vorbehandelte Patienten als weitestgehend gut verträgliche Therapie betrachtet. Als primären Endpunkt untersuchte die Studie das progressionsfreie Überleben. Die sekundären Endpunkte der Studie beinhalten Sicherheit, Ansprechrate und Gesamtüberleben.

MabCampath erhielt 2001 die beschleunigte Zulassung für die Behandlung von B-CLL bei Patienten, die bereits mit alkylierenden Substanzen behandelt worden waren und bei denen eine Fludarabinphosphat-Therapie nicht angeschlagen hatte. Schering besitzt die exklusiven weltweiten Marketing- und Vertriebsrechte für das Produkt, das in den USA von Berlex Oncology, einem Unternehmen der US-Tochter von Schering, Berlex Laboratories, unter der Bezeichnung Campath vertrieben wird. Schering und Genzyme arbeiten gemeinsam an der Entwicklung von MabCampath für onkologische und andere Indikationen.

Die Aktie von Schering notiert aktuell mit einem Minus von 0,01 Prozent bei 85,39 Euro.

(korrigierte Fassung)

WASHINGTON (Dow Jones)--Die US-Gesundheitsbehörde FDA hat die Wiederzulassung des Multiple-Sklerose-Medikaments "Tysabri" genehmigt. Tysabri wurde gemeinsam von der Biogen Idec Inc und Elan Corp entwickelt und vermarktet. Die Unternehmen mussten das Medikament im Februar 2005 vom Markt nehmen, nachdem zwei Patienten im Zusammenhang mit der Einnahme des Medikaments an der seltenen Krankheit PML gestorben waren.

Bereits Anfang März hatte ein Beratergremium der FDA eine Wiederzulassung von Tsyabri einstimmig empfohlen. Die US-Gesundheitsbehörde kündigte jedoch Mitte März an, ihre Untersuchung des Medikaments Anzeige
 
um bis zu 90 Tage verlängern. Nach Unternehmensangaben soll das Medikament nun im Juli wieder erhältlich sein. Laut Analystenaussagen vom März hängt die Zukunft des schuldenbeladenen irischen Pharmakonzerns Elan von der Entscheidung der FDA ab.

Die Verwendung wurde jedoch beschränkt. Nach Angaben der FDA soll Tysabri künftig nur bei Multiple-Sklerose-Patienten angewendet werden, bei denen andere Therapien fehlgeschlagen sind. Zudem sollte Tysabri nicht in Kombination mit anderen Medikamenten genommen werden, die das Immunsystem beeinflussen.

Merck KGaA: Erbitux(R) (cetuximab) hält weiterhin sein Versprechen
Dienstag 6. Juni 2006, 08:43 Uhr



ATLANTA, Georgia, June 6 /PRNewswire/ --


- Kurzreferate: 3085, 3509, 3535, 3549, 3555, 3556, 5537, 7109



- Veranstaltungsort: 42. Jahrestagung der American Society of Clinical
Oncology (ASCO) 2006, Atlanta, Georgia



- Merck KGaA veröffentlicht eine Vielzahl neuer Daten über Erbitux(R)
(cetuximab) anlässlich der ASCO Jahrestagung



Die anlässlich der 42. Jahrestagung der American Society of Clinical
Oncology (ASCO) vorgestellten Daten aus klinischen Versuchen mit 1.147
Patienten, die zuvor nicht mehr auf die auf der Basis von Irinotecan
ANZEIGE
 
durchgeführte Behandlung ihres metastasierenden kolorektalen Karzinoms (mCRC)
angesprochen hatten, lieferten den Beweis einer mittleren Überlebensdauer von
9,2 Monaten durch eine gezielte Krebstherapie mit Erbitux(R) (cetuximab) und
Irinotecan.(1) Diese Ergebnisse der Versuche mit mehr als 1.000 Patienten
bestätigen die Wirksamkeit und Sicherheit von Erbitux plus Irinotecan an
vorbehandelten Patienten und liefern den weiteren Beweis, dass Erbitux sein
Versprechen hält.



"Die hier vorgetragenen Ergebnisse ermutigen uns sehr," sagte Professor
Hansjochen Wilke von den Kliniken Essen Mitte, Essen, Deutschland, der
Versuchsleiter der Studie. "Die Behandlung von Patienten, die auf
Standard-Chemotherapien nicht mehr ansprechen, ist für Ärzte eine
Herausforderung. Die Therapie mit Erbitux plus Irinotecan erweist sich als
hochwirksame Behandlung für diese Patienten und ist zum Behandlungsstandard
von Patienten geworden, deren Behandlung mit einer zuvor durchgeführten auf
Irinotecan basierenden Therapie gescheitert war."



Die Studie unter dem Namen MABEL[a] wurde in 197 Zentren in acht
europäischen Ländern durchgeführt und wertete progressionsfreie
Überlebensraten von Patienten mit mCRC aus, deren Erkrankung auf die zuvor
durchgeführte Therapie mit Irinotecan nicht ansprach. Die Patienten wurden
mit Erbitux in Verbindung mit Irinotecan behandelt. Die progressionsfreie
Überlebensrate betrug 61% bei 12 Wochen und 34% bei 24 Wochen und bestätigte
damit deutlich die bereits in zuvor durchgeführten Studien beobachtete
Wirksamkeit dieser Behandlungsmöglichkeit.(1)



Ferner wurden vorläufige Befunde aus einem klinischen Versuch mit Erbitux
plus Chemotherapie bei zuvor unbehandelten Patienten mit mCRC von Prof. Dr.
med. Alan Venook von der University of California, San Francisco im Namen der
CALGB[b] (Chronic & Acute Leukemia Group) gemeldet. Patienten mit
unbehandeltem mCRC wurden in die Studie aufgenommen und zur Behandlung
entweder durch Chemotherapie (ausgewählt zwischen Irinotecan/5FU/LV [FOLFIRI]
oder Oxaliplatin/ 5FU/LV [FOLFOX]) oder Chemotherapie plus Erbitux
randomisiert. Die Studie, CALGB 80203, wurde im Jahr 2004 initiiert und
sollte ursprünglich ca. 2.200 Patienten aufnehmen. Die Registrierung wurde
nach der Aufnahme von 238 Patienten aufgrund eines sich entwickelnden
Standards bei der Erstbehandlung von mCRC beendet. Der primäre Endpunkt der
Studie war das allgemeine Überleben; die sekundären Endpunkte enthielten
Reaktionsrate, progressionsfreies Überleben und Toxizität. Da die Studie
vorzeitig beendet wurde, kann sie nicht zur statistischen Auswertung des
progressionsfreien und allgemeinen Überlebens verwendet werden und
Folgerungen können daraus unmöglich gezogen werden. Jedoch war die
Reaktionsrate bei Patienten, die durch die Verbindung von Erbitux und
Chemotherapie behandelt wurden, signifikant höher als die bei Patienten,
die nur eine Chemotherapie erhielten (52% respektive 38%, p=0.029).(2)



Untersuchung eines alternativen Dosierungsplans für Erbitux



Weitere auf der ASCO Jahrestagung vorgestellte Daten zeigen, dass die
Verabreichung von Erbitux jede zweite Woche (anstelle der dem gegenwärtigen
Standard entsprechenden wöchentlichen Dosierung) ein alternativer
Dosierungsplan für Patienten sein könnte.(3) Es könnte nachgewiesen werden,
dass die Verabreichung von Erbitux in Dosen von 500 mg/msquared jede zweite
Woche ähnliche pharmakokinetische Ergebnisse liefert, verglichen mit der
aktuellen wöchentlichen Standarddosierung von 250 mg/msquared. Dieses
Ergebnis ist von grosser Wichtigkeit, da es Patienten und Onkologen einen
flexibleren Dosierungsvorteil bietet.



Erbitux Phase-III-Studien werden wie geplant fortgesetzt



Auf der Tagung wurden auch frühe Ergebnisse mehrerer internationaler
klinischer Phase-III-Versuche mit mehr als 4.000 Patienten präsentiert,
die deutlich machten, dass die unabhängigen Data Safety Monitoring Boards
(DSMB) die Fortsetzung der Versuche mit Erbitux empfehlen.(4-7) Diese
klinischen Phase-III-Versuche werden mit schwierigen Krebsarten
durchgeführt, zu denen mCRC, Plattenepithelkarzinom des Kopfes und Halses
(SCCHN) und nicht kleinzelliges Bronchialkarzinom (NSCLC) zählen.(4-7)



Zwei umfangreiche Phase-III-Studien werden zu mCRC durchgeführt:
EPIC[c],(4) (Untersuchung der Anwendung von Erbitux in Verbindung mit
Irinotecan nach Versagen einer auf Oxaliplatin basierenden Chemotherapie an
1.301 Patienten) und CRYSTAL[d],(5) (Untersuchung von Erbitux mit Irinotecan
an 1.221 Patienten als Erstbehandlung). Diese Ergebnisse erlauben die
Fortsetzung der Phase-III-Studien zur weiteren Forschung, aufbauend auf den
bereits aussergewöhnlichen Phase-II-Studien, die beständig hohe
Reaktionsraten von bis zu 81% bei der Erstbehandlung von mCRC zeigten.
Hierdurch konnten die bereits auf die Leber übergegriffenen, zuvor
inoperablen Metastasen bei nahezu einem von vier Patienten chirurgisch
entfernt werden.(8,9,10) Bislang ist bei mCRC der einzige Ansatz mit einer
Hoffnung auf Heilung die Resektion von vorwiegend in der Leber gefundenen
Metastasen.(11,12)



Die Phase-III-Studie mit dem Namen EXTREME [e](6) untersucht die
Erstbehandlung mit Erbitux in Verbindung mit einer Chemotherapie (Cisplatin
plus 5-FU oder Carboplatin plus 5-FU) an 442 Patienten mit rekurrenten
und/oder metastatischen SCCHN.



Die Phase-III-Studie FLEX[f] (7) untersucht die Überlebenschancen einer
Erstbehandlung mit Erbitux plus Chemotherapie (Cisplatin und Vinorelbin) im
Vergleich zu einer ausschliesslich durchgeführten Chemotherapie an 1.125
Patienten mit fortgeschrittenem NSCLC.



"Die anlässlich der diesjährigen ASCO Jahrestagung vorgestellten Daten
über Erbitux bekräftigen die überragende Wirksamkeit bei der Erstbehandlung
und späteren Therapien bei Patienten mit metastatischem kolorektalem Krebs
nach zuvor fehlgeschlagener Chemotherapie," sagte Dr. Wolfgang Wein, Senior
Vice President und Leiter der Global Oncology Commercialization' bei der
Merck KGaA. "Die neuen Daten, die beweisen, dass Erbitux jede zweite Woche
verabreicht werden kann, sind für uns auch sehr ermutigend."



Hinweise für Redakteure



Informationen zu ERBITUX



ERBITUX(R) ist ein erstklassiger und sehr aktiver, auf den epidermalen
Wachstumsfaktor-Rezeptor (EGFR) gerichteter IgG1 monoklonaler Antikörper. Als
monoklonaler Antikörper unterscheidet sich die Wirkungsweise von Erbitux
von standardmässigen, nicht selektiven Chemotherapien dadurch, dass er
spezifisch auf den EGFR gerichtet ist und an den EGFR bindet. Diese Bindung
hemmt die Aktivierung des Rezeptors und des nachfolgenden
Signalübertragungspfads und führt somit zu einer Reduktion der Invasion des
gesunden Gewebes durch Tumorzellen und die Distribution von Tumoren an neuen
Stellen. Man geht auch davon aus, dass das Mittel die Fähigkeit von
Tumorzellen hemmt, den durch Chemotherapie und Radiotherapie verursachten
Schaden zu reparieren und die Bildung von neuen Blutgefässen innerhalb von
Tumoren zu hemmen, was zu einer allgemeinen Unterdrückung des Tumorwachstums
zu führen scheint. Die am häufigsten gemeldete Nebenwirkung von Erbitux ist
ein akneähnlicher Hautauschlag, der mit dem guten Ansprechen auf die Therapie
zusammenzuhängen scheint. Bei etwa fünf Prozent der Patienten kann während
der Behandlung mit Erbitux eine Überempfindlichkeit festgestellt werden; rund
die Hälfte davon ist schwerwiegend.



Erbitux ist in 53 Ländern bereits zur Behandlung von Patienten mit
EGFR-positivem metastasierendem kolorektalem Karzinom, das auf
Irinotecan-Therapien nicht mehr anspricht, zur Anwendung in Kombination mit
Irinotecan zugelassen: der Schweiz, den USA, Mexiko, Argentinien, Chile,
Island, Norwegen, der Europäischen Union, Peru, Australien, Kroatien, Israel,
Bulgarien, Panama, Guatemala, Kolumbien, Singapur, Hongkong, Südkorea,
Kanada, Ecuador, Malaysia, den Philippinen, Taiwan, China, Indien, Libanon,
Venezuela und Nicaragua. In den USA, Argentinien, Chile, Mexiko, Peru,
Singapur, Australien, Panama, Kolumbien, Guatemala, Hongkong, Kanada,
Ecuador, den Philippinen, Libanon, Venezuela und Nicaragua ist Erbitux auch
als Monowirkstoff zugelassen.



Ferner ist Erbitux in Kombination mit einer Radiotherapie zur Behandlung
lokal fortgeschrittener Plattenepithelkarzinome des Kopfes und Halses (SCCHN)
in der Schweiz, Argentinien, Kolumbien, den USA, der Europäischen Union,
Norwegen, Island und den Philippinen zugelassen. In Argentinien, den USA und
den Philippinen ist Erbitux auch als Monotherapie bei Patienten mit
rekurrenten und/oder metastatischen SCCHN zugelassen, die auf frühere
Chemotherapien nicht mehr angesprochen haben.



Informationen zur Merck KGaA



Die Merck KGaA, Darmstadt, hat die Lizenz zur Vermarktung von Erbitux
ausserhalb der USA und Kanada im Jahre 1998 von ImClone Systems Incorporated
of New York erworben. In Japan teilt sich die Merck KGaA das exklusive
Marketing-Recht mit ImClone Systems.



Die Merck KGaA ist dem stetigen Fortschritt der Behandlungsmethoden in
der Onkologie verpflichtet. Derzeit untersucht das Unternehmen neuartige
Therapien in zielgerichteten Bereichen, wie z. B. dem Einsatz von Erbitux
beim kolorektalen Karzinom, Plattenepithelkarzinom im Kopf- und Nackenbereich
und nicht kleinzelligen Bronchialkarzinom. Die Merck KGaA hat auch die Rechte
zur Behandlung von Krebs mit UFT(R) (Tegafur-Uracil) erworben - einer oralen
Chemotherapie, die mit Folinsäure (FA) zur Erstbehandlung von metastatischem
kolorektalem Krebs verabreicht wird.



Die Merck KGaA untersucht zurzeit unter anderen Krebstherapien auch den
Einsatz von Stimuvax(R) (zuvor als BLP25 Liposom-Impfstoff bezeichnet) bei
der Behandlung von nicht kleinzelligem Bronchialkarzinom. Der Impfstoff
befindet sich seit September 2004 im beschleunigten Zulassungsverfahren der
FDA. Merck erwarb die exklusiven weltweiten Lizenzen von Biomira Inc. in
Edmonton, Alberta, Kanada mit Ausnahme von Kanada, wo die Unternehmen sich
die Rechte teilen.

Phase III Study of Avastin(R) in Advanced Pancreatic Cancer Does Not Meet Primary Endpoint
Tuesday June 27, 1:30 am ET  
Genentech Remains Committed to Broad Avastin Development Program in Multiple Tumor Types and Stages of Disease


SOUTH SAN FRANCISCO, Calif., June 27 /PRNewswire-FirstCall/ -- Genentech, Inc. (NYSE: DNA - News) today announced that a Phase III trial of Avastin® (bevacizumab) in combination with gemcitabine chemotherapy as first-line treatment for advanced pancreatic cancer did not meet its primary endpoint of overall survival. The trial was stopped at the recommendation of an independent data monitoring board based on an interim analysis indicating that it is very unlikely that significant differences in overall survival will be shown between treatment arms as the data mature. The study was not stopped due to safety events and no new safety concerns related to Avastin were observed in this trial. Data from the study will be presented at an upcoming medical meeting.

"We are disappointed in these results and will be evaluating the data to understand potential reasons why Avastin did not add a clinical benefit in this trial," said Hal Barron, M.D., senior vice president, Development and chief medical officer for Genentech. "Chemotherapy has had a limited impact in advancing outcomes for patients with pancreatic cancer, and treatments that may improve survival are desperately needed. We will continue to explore novel biologic and targeted therapy approaches that may lead to improved clinical outcomes for patients with pancreatic cancer."

This randomized, controlled study of 602 patients was sponsored by the National Cancer Institute (NCI) and conducted by a network of researchers led by the Cancer and Leukemia Group B (CALGB). The trial was initiated based on results from a single-arm Phase II study combining Avastin with gemcitabine in pancreatic cancer. The Phase II study results were first presented in 2003 at the annual meeting of the American Society of Clinical Oncology.

Genentech is pursuing a broad development program for Avastin that currently includes 130 clinical trials across 25 different types of cancer. As part of this program, a randomized Phase III study evaluating the addition of Avastin to a standard regimen of gemcitabine and Tarceva® (erlotinib) in patients with pancreatic cancer is currently being conducted by Roche.

Avastin, in combination with intravenous 5-FU-based chemotherapy, was approved by the U.S. Food and Drug Administration (FDA) in February 2004 for first-line treatment of patients with metastatic colorectal cancer, and received approval in June 2006 for second-line treatment of colorectal cancer. The company recently submitted supplemental Biologics License Applications (sBLA) to the FDA for Avastin in advanced non-small cell lung cancer, other than predominant squamous histology (April 2006), and for locally recurrent or metastatic breast cancer (May 2006).

About the CALGB 80303 Trial

This randomized, placebo-controlled, multi-center trial, known as CALGB 80303, was sponsored by the NCI, part of the National Institutes of Health (NIH), under a Cooperative Research and Development Agreement between the NCI and Genentech, and conducted by a network of researchers led by the CALGB. In this study, 602 patients were enrolled at approximately 200 sites and were randomized to receive treatment with gemcitabine plus Avastin or gemcitabine plus placebo as a first-line therapy. Patients who had received prior chemotherapy for metastatic disease, adjuvant chemotherapy within the previous four weeks or any prior treatment with gemcitabine or Avastin in the adjuvant or metastatic setting were excluded. Patients with a prior history of bleeding events and those who had a surgical procedure, open biopsy, or significant traumatic injury 28 days prior were also excluded from the study. The statistical plan included pre-specified futility analyses that were conducted and reviewed by an independent data monitoring board.

About Avastin

Avastin is a therapeutic antibody designed to inhibit Vascular Endothelial Growth Factor (VEGF), a protein that plays an important role in tumor angiogenesis and maintenance of existing tumor vessels. By inhibiting VEGF, Avastin is designed to interfere with the blood supply to a tumor, a process that is thought to be critical to a tumor's growth and metastasis. For full prescribing information and boxed warnings on Avastin and information about angiogenesis, visit www.gene.com. For more information on Avastin, visit www.avastin.com.

Avastin, in combination with intravenous 5-FU-based chemotherapy, is indicated for first- or second-line treatment of patients with metastatic carcinoma of the colon or rectum. The FDA first approved Avastin on February 26, 2004 as a first-line treatment for metastatic colorectal cancer in combination with intravenous 5-FU-based chemotherapy. Approval was based on data from two trials. The pivotal trial was a large, placebo-controlled, randomized study that demonstrated a prolongation in the median survival of patients treated with Avastin plus the IFL (5-FU/leucovorin/CPT-11) chemotherapy regimen by approximately five months, compared to patients treated with the IFL chemotherapy regimen alone (20.3 months versus 15.6 months). The addition of Avastin to IFL improved overall survival by 52 percent (based on a hazard ratio of 0.66). In addition, this study demonstrated an improvement in progression-free survival of more than four months (10.6 months in the Avastin/IFL arm compared to 6.2 months in the IFL-alone arm).

Avastin Safety Profile

Avastin has a well-established safety profile. In Genentech-sponsored studies, the most serious adverse events associated with Avastin were gastrointestinal perforation, wound healing complications, hemorrhage, arterial thromboembolic events, hypertensive crisis, nephrotic syndrome and congestive heart failure. The most common adverse events in receiving Avastin were asthenia, pain, abdominal pain, headache, hypertension, diarrhea, nausea, vomiting, anorexia, stomatitis, constipation, upper respiratory infection, epistaxis, dyspnea, exfoliative dermatitis and proteinuria.

About the Avastin Development Program

Based on data showing that VEGF may play a broad role in a range of cancers, Genentech is pursuing a broad development program for Avastin that currently includes 130 clinical trials across 25 different types of cancer. Avastin is being evaluated in Phase III clinical trials for its potential use in adjuvant and metastatic colorectal, renal cell (kidney), breast, pancreatic, non-small cell lung, prostate and ovarian cancers. Avastin is also being evaluated in earlier stage trials as a potential therapy in a variety of solid tumor cancers and hematologic malignancies. In April 2006, Genentech submitted an sBLA for Avastin plus platinum-based chemotherapy for first-line treatment of advanced non-small cell lung cancer other than predominant squamous histology. In May 2006, Genentech submitted an sBLA for Avastin in combination with taxane chemotherapy for patients who have not previously received chemotherapy for their locally recurrent or metastatic breast cancer. For further information about Avastin clinical trials, please call 888-662-6728.

About VEGF and Tumor Angiogenesis

Genentech is a leader in research and product development in the area of angiogenesis, the process by which new blood vessels are formed. The link between angiogenesis and cancer growth has been discussed by many researchers for decades. It wasn't until 1989 that a key growth factor influencing the process, VEGF, was discovered by Napoleone Ferrara, M.D., a staff scientist at Genentech. Dr. Ferrara and his team at Genentech cloned VEGF, providing some of the first evidence that a specific angiogenic growth factor existed. This research was published in the journal Science in 1989. Dr. Ferrara then created a mouse antibody to this protein.

In 1993, in a study published in Nature, Dr. Ferrara and his team demonstrated that the antibody directed against VEGF could suppress angiogenesis and tumor growth in preclinical models, providing compelling evidence that VEGF can play a critical role in tumor growth. Clinical studies with a humanized version of the antibody, Avastin, began in 1997.

About Pancreatic Cancer

The American Cancer Society estimates 33,730 Americans will be diagnosed with pancreatic cancer and 32,300 will die of the disease in 2006. Pancreatic cancer, characterized by early, distant spread, is the fourth leading cause of cancer death in the United States. For patients with advanced pancreatic cancer, the five-year survival rate across all stages is less than 1 percent, with most patients dying within one year of diagnosis.

About Genentech BioOncology

Genentech is committed to changing the way cancer is treated by establishing a broad oncology portfolio of innovative, targeted therapies with the goal of improving patients' lives. The company is the leading provider of anti-tumor therapeutics in the United States. Genentech is conducting clinical development programs for Rituxan® (Rituximab), Herceptin® (Trastuzumab), Avastin® (bevacizumab), and Tarceva® (erlotinib), and markets all four products in the United States, either alone (Avastin and Herceptin) or with Biogen Idec Inc. (Rituxan) or OSI Pharmaceuticals, Inc. (Tarceva).

The South San Francisco, Calif. biotech company's application was granted priority review by the agency at the end of December, which gave the FDA six months to decide whether or not to approve Lucentis.
The application was based on data from Phase III studies that showed the treatment not only maintained the vision of the majority of wet AMD patients, but in some cases, improved it.
"We are thrilled that after nearly a decade of rigorous study, Lucentis is approved, and we look forward to getting it to patients quickly," company spokeswoman Dawn Kalmar said. Shipments will start today.
Genentech said on a conference call that it has priced Lucentis at $1,950 a vial and is estimating the average dosage will be five to seven times a year. That would bring the average annual cost of the treatment to $9,750 to $13,650 a year.
Lucentis will enter a marketplace that includes Visudyne, an intravenously injected, light-activated treatment made by a QLT Therapeutics (QLTI : qlt inc com

Wet AMD is caused by the growth of abnormal blood vessels that leak and bleed and cause blindness-inducing scar tissue. Serious vision loss by the more common, dry form of AMD is rare.
Lucentis will be also be competing against one of Genentech's own drugs, Avastin, which is approved to treat colorectal cancer but which company executives have acknowledged is increasingly being used by ophthalmologists as an "off-label" treatment for wet AMD.
The company has no plans to seek approval for Avastin to be used to treat the eye condition. "Our interpretation of Avastin use [for AMD] is it tells you how big of an unmet need there is," Genentech's president of product development, Susan Desmond-Hellman, told MarketWatch in an interview back in January.

Dendreon Announces Publication of Pivotal Phase 3 Study Highlighting Survival Benefit and Safety Profile of PROVENGE in Men With Advanced Prostate Cancer
Thursday June 29, 6:00 pm ET  
First Cancer Immunotherapy to Demonstrate a Survival Benefit in a Randomized Phase 3 Study
Company Plans to Submit BLA to U.S. Food and Drug Administration Later This Year


SEATTLE, June 29 /PRNewswire-FirstCall/ -- Dendreon Corporation (Nasdaq: DNDN - News) today announced the publication of the results of its pivotal Phase 3 study (D9901) of PROVENGE® (sipuleucel-T) in the July issue of the Journal of Clinical Oncology. The article highlights the significant survival benefit and favorable safety profile of PROVENGE, the Company's investigational active cellular immunotherapy, in men with advanced androgen-independent prostate cancer. The Company plans to submit a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) later this year to obtain approval to market PROVENGE.

"This trial is an important milestone in the development of new treatments for prostate cancer patients. The survival benefit that was observed has the potential to offer important benefits to patients, and represents the first time an immunotherapy has provided a survival advantage in prostate cancer," said Eric J. Small, M.D., professor of medicine and urology at the University of California, San Francisco and lead author of the publication. "In addition to the observed survival benefit, PROVENGE has a very favorable toxicity and safety profile, with the most common side effects being low grade fevers and chills. A favorable benefit-to-risk profile will be appealing to patients with advanced stage prostate cancer who currently have few appealing treatment options available to them."

The double-blind, placebo-controlled Phase 3 Study D9901 showed that the group of men with asymptomatic, metastatic, androgen-independent prostate cancer who received PROVENGE had a median survival time 4.5 months longer than the median survival seen in the group that had been assigned to receive placebo. For the men who received PROVENGE, there was a 41 percent overall reduction in the risk of death (p-value = 0.010; HR = 1.7). In addition, 34 percent of patients receiving PROVENGE were alive 36 months after treatment compared to 11 percent of patients randomized to receive placebo. These data will form the basis of the Company's BLA to the FDA for marketing approval, which the Company plans to submit later this year.

Patients in the PROVENGE arm had a 31 percent delay in their time to disease progression compared to patients in the placebo arm (p-value = 0.052; HR = 1.45). Furthermore, patients receiving PROVENGE had an approximately 8-fold increase in their T-cell immunity after treatment compared to the placebo group (p < 0.001).

"The survival benefit demonstrated in this trial, combined with the favorable safety profile of PROVENGE, will form the basis for our BLA submission to the FDA later this year," said Mark Frohlich, M.D., vice president of clinical affairs at Dendreon. "We look forward to making this active cellular immunotherapy available for the treatment of the many men with advanced prostate cancer."

The D9901 study was conducted at 19 institutions in the United States and enrolled 127 men with asymptomatic, metastatic androgen-independent (hormone-refractory) prostate cancer. Patients were randomized in a 2:1 ratio to receive three infusions of PROVENGE (n=82) or placebo (n=45) every two weeks for a total of three infusions over a one month period.

Treatment with PROVENGE was generally well tolerated. The majority of side effects were mild, including infusion-related fever and chills that were usually of low grade and typically lasted for one to two days following infusion.

About PROVENGE (sipuleucel-T)

PROVENGE (sipuleucel-T) is an investigational product that may represent the first in a new class of active cellular immunotherapies (ACIs) that are uniquely designed to stimulate a patient's own immune system. ACIs hold promise because they may provide patients with a meaningful survival benefit with low toxicities. PROVENGE targets the prostate cancer antigen, prostatic acid phosphatase (PAP), which is found in approximately 95 percent of prostate cancers. PROVENGE is in late-stage development for the treatment of patients with advanced prostate cancer. In clinical studies, patients typically received three infusions over a one-month period as a complete course of therapy.

About Prostate Cancer

Prostate cancer is the most common non-skin cancer in the United States and the third most common cancer worldwide. More than one million men in the United States have prostate cancer, with an estimated 232,000 new cases of prostate cancer diagnosed each year. More than 30,000 men die each year of the disease.

Buckyball-Antibody Combination Delivers Antitumor

Buckyball-Antibody Combination Delivers Antitumor Drugs

Combining a monoclonal antibody known to target melanoma tumors with multiple C60 buckyballs, researchers at Rice University and the University of Texas M. D. Anderson Cancer Center have developed a new way to deliver multiple drugs simultaneously to tumors. Unlike other methods that use multiple targeting agents, such as antibodies, to deliver individual drug-loaded nanoparticles to malignant cells, this new approach attaches multiple nanoparticles to an individual tumor-targeting antibody.

In research published in the journal Chemical Communications, Lon Wilson, Ph.D., and colleagues at Rice University, working with Michael Rosenblum, Ph.D., and collaborators at The M. D. Anderson Cancer Center, describe the methods they used to attach as many as 40 water-soluble buckyballs onto a single antibody known as ZME-018. The M. D. Anderson Cancer Center investigators had already shown that ZME-018, which binds to a tumor protein known as gp240, will deliver anticancer drugs into melanoma tumors, while the Rice group has been developing buckyballs as drug delivery agents.

One potential advantage of attaching multiple nanoparticles to a single antibody is that it may be possible to load a different anticancer drug into each nanoparticle. "The idea that we can potentially carry more than one Taxol™ per buckyball is exciting, but the real advantage of fullerene immunotherapy over other targeted therapeutic agents is likely to be the buckyball's potential to carry multiple drug payloads, such as Taxol™ plus other chemotherapeutic drugs," said Wilson. "Cancer cells can become drug resistant, and we hope to cut down on the possibility of their escaping treatment by attacking them with more than one kind of drug at a time."

While it's possible to attach drug molecules directly to antibodies, researchers have not been able to attach more than a handful of drug molecules to an antibody without significantly changing its targeting ability. That happens, in large part, because the chemical bonds that are used to attach the drugs -- strong, covalent bonds -- tend to block the targeting centers on the antibody's surface. If an antibody is modified with too many covalent bonds, the chemical changes will destroy its ability to recognize the cancer it was intended to attack.

The investigators originally had planned to overcome this limitation by attaching multiple molecules of the anticancer agent paclitaxel to each buckyball, which would then be connected chemically to the antibodies. To the team members' surprise, many more buckyballs than expected attached themselves to the antibody. Moreover, the buckyballs stuck tightly to the antibodies without the need to form chemical bonds, so the increased payload did not significantly change the targeting ability of the antibody.

This work is detailed in a paper titled, "Fullerene (C60) immunoconjugates: interaction of water-soluble C60 derivatives with the murine anti-gp240 melanoma antibody." This paper was published online in advance of print publication. An abstract of this paper is available at the journal's website. View abstract.

Britain Seeks Tighter Drug Trial Rules
Monday July 24, 9:12 am ET

          §
British Drug Industry Proposes Stricter Clinical Trial Guidelines
LONDON (AP) -- Britain's pharmaceutical industry on Monday proposed strict new guidelines for testing some experimental drugs after a disastrous trial that left six men in comas.
In March, six healthy volunteers participated in a trial for test drug TGN1412, designed to treat leukemia, autoimmune and inflammatory diseases. Within hours of being given doses of the drug they suffered convulsions, organ failure and ultimately lapsed into comas.

ADVERTISEMENT

A report by the Association of the British Pharmaceutical Industry and the BioIndustry Association, the industry's two largest trade associations, proposed that drugs which stimulate the immune system should be subject to strict new safety standards when they are tested on humans for the first time.
The groups recommended that trials of drugs such as TGN1412 should be staggered, with only one person receiving the drug on the first day.
Their report also said trials should only be carried out at hospitals with intensive care facilities which are able to deal with unforeseen problems.
Martyn Day, a lawyer who represents four of the TGN1412 trial volunteers, said the report "starts the process of learning from this dreadful tragedy which has caused the six young victims to have such a terrible cloud hanging over their lives."
German drug maker TeGenero AG, which produced TGN1412, filed for bankruptcy protection earlier this month.

Biogen Idec, Genentech Say Rituxan Passes Mid-Stage Trial in Multiple Sclerosis Study


NEW YORK (AP) -- Drug makers Biogen Idec Inc. and Genentech Inc. said Monday a mid-stage study of Rituxan showed it was effective in treating multiple sclerosis.
The Food and Drug Administration originally approved the drug in 1997 for the treatment of cancer. It was developed by Cambridge, Mass-based Biogen and is co-marketed with South San Francisco, Calif-based Genentech in the United States.

The companies said the treatment reached its primary endpoint in reducing the number of gadolinium enhancing T1 lesions, or indicators of relapsing forms of MS, in a 104-patient study. The clinical trial compared Rituxan to a placebo and took place over 24 weeks.

Patients involved in the study will be followed for an additional 48 weeks as the companies monitor the long-term safety affects of the treatment.

MS, an autoimmune disease, is the leading cause of neurological disorders in young adults, the companies said, with the relapsing form of the disease accounting for 65 percent of all MS cases.

Shares of Genentech added 11 cents to $80.11 in morning trading on the New York Stock Exchange, while shares of Biogen rose 40 cents to $44.68 on the Nasdaq.

Genentech and Biogen Idec Announce Positive Results From a Phase II Trial of Rituxan in Relapsing-Remitting Multiple Sclerosis
Monday August 28, 9:00 am ET


SOUTH SAN FRANCISCO, Calif. and CAMBRIDGE, Mass., Aug. 28 /PRNewswire-FirstCall/ -- Genentech, Inc. (NYSE: DNA - News) and Biogen Idec, Inc. (Nasdaq: BIIB - News) announced today that a Phase II study of Rituxan® (Rituximab) for relapsing-remitting multiple sclerosis (RRMS) met its primary endpoint. The study of 104 patients showed a statistically significant reduction in the total number of gadolinium enhancing T1 lesions observed on serial MRI scans of the brain at weeks 12, 16, 20 and 24 in the Rituxan-treated group compared to placebo. Genentech and Biogen Idec will continue to analyze the study results and will submit the data for presentation at an upcoming medical meeting.

"These initial results exceeded our expectations," said Hal Barron, M.D., Genentech senior vice president, development and chief medical officer. "Showing a significant benefit at 24 weeks in this small Phase II trial supports our hypothesis that selective B-cell targeted therapy may play an important role in the treatment of MS."

"Biogen Idec is committed to offering multiple options for people living with MS, a devastating disease. We are very encouraged by these data and look forward to learning more about the potential of Rituxan as a therapy to treat MS," said Alfred Sandrock, M.D., Ph.D., senior vice president, neurology research and development, Biogen Idec.

Rates of overall adverse events and serious adverse events were comparable between the two treatment groups. Serious infectious adverse events occurring in Rituxan-treated patients included gastroenteritis and bronchitis. The overall rates of infection were comparable among the two treatment groups with an increase in the rates of nasopharyngitis, upper respiratory tract infections, urinary tract infections and sinusitis in the Rituxan-treated patients. There were more first infusion-related reactions with Rituxan, the majority of which were mild to moderate and were generally reversible with medical intervention. The companies continue to monitor the long-term safety of Rituxan treatment.

About the Study

This Phase II randomized, double-blind, parallel-group, placebo-controlled, multi-center study was designed to evaluate safety and efficacy of Rituxan in adults with RRMS. A total of 104 patients at 48 sites in the U.S. and Canada were randomized to receive either a single treatment course of Rituxan or placebo. Gadolinium-enhancing lesions visible by MRI scans were assessed at 12, 16, 20 and 24 weeks. Patients will continue to be followed for 48 weeks.

About MS and RRMS

MS is a chronic autoimmune disease in which the immune system is thought to attack the body's own myelin, a fatty substance that surrounds and protects the nerve fibers of the brain, optic nerves and spinal cord. There are four types of MS with a wide variety of symptoms and different courses of disease progression.

MS is the leading cause of neurological disability in young adults. Neurological disability typically accumulates over time and includes muscle weakness and spasticity, balance and coordination problems, as well as memory impairment and depression. Other symptoms include numbness, pain, slurred speech and blurred vision. Many patients experience fatigue and problems with bladder, bowel or sexual function.

RRMS is the most common form of MS and accounts for approximately 65 percent of all MS cases. RRMS is characterized by acute exacerbations with full or partial recovery between attacks. The disease does not progress between attacks.

Rituxan Safety Profile in Oncology and Autoimmune Diseases

The safety profile of Rituxan has been established in more than 960,000 patient exposures over a period of eight years.

In general, the adverse events observed in patients with RA, an autoimmune disease, were similar in type to those seen in patients with non-Hodgkin's lymphoma (NHL). The most common adverse events observed in patients treated with Rituxan for RA in clinical trials were infusion reactions and infections. No significant change in average immunoglobulin levels was observed in Rituxan-treated patients in clinical trials. There was no increase in hematologic malignancies, demyelinating events or risk of opportunistic infections (including tuberculosis) in Rituxan-treated patients over 24 weeks of treatment. Although 5 percent of Rituxan-treated patients developed human anti-chimeric antibodies (HACA), this was not associated with loss of clinical response or additional safety observations.

The majority of patients experience infusion-related symptoms with their first Rituxan infusion. These symptoms include but are not limited to: flu-like illness, fever, chills/rigors, nausea, urticaria, headache, bronchospasm, angioedema, hypotension and hypoxia. These symptoms vary in severity and generally are reversible with medical intervention.

Severe infusion reactions have been reported in patients treated with Rituxan, some with fatal outcomes in patients with NHL. These severe reactions typically occur during the first infusion. The most severe manifestations and sequelae include pulmonary infiltrates, acute respiratory distress syndrome, myocardial infarction, ventricular fibrillation, cardiogenic shock, and anaphylactic and anaphylactoid events. Patients who develop clinically significant infusion reactions should have their Rituxan infusion discontinued and receive medical treatment. Acute renal failure requiring dialysis with instances of fatal outcome has been reported in the setting of tumor lysis syndrome following treatment with Rituxan. Severe mucocutaneous skin reactions, some with fatal outcome, have been reported in association with Rituxan treatment. Patients experiencing a severe mucocutaneous reaction should not receive any further infusions and seek prompt medical evaluation. Abdominal pain, bowel obstruction and perforation, in some cases leading to death, were observed in patients receiving Rituxan in combination with chemotherapy for diffuse large B-cell (DLBCL), CD20-positive, non-Hodgkin's lymphoma. Other serious or potentially life-threatening adverse reactions that have been reported following Rituxan therapy include Hepatitis B reactivation with fulminant hepatitis, other viral infections, hypersensitivity reactions, and cardiac arrhythmias.

About Rituxan

Rituxan is a therapeutic antibody that targets and selectively depletes CD20-positive B-cells without targeting stem cells or existing plasma cells. In addition to RRMS, Rituxan is being studied in primary progressive MS, for which there is currently no FDA-approved therapy. Rituxan is being studied in other autoimmune diseases with significant unmet medical needs, including systemic lupus erythematosus, lupus nephritis and ANCA-associated vasculitis.

Rituxan, discovered by Biogen Idec, first received FDA approval in November 1997 for the treatment of relapsed or refractory, low-grade or follicular, CD20-positive, B-cell non-Hodgkin's lymphoma. It was also approved in the European Union under the trade name MabThera® in June 1998. In addition, Rituxan received FDA approval in February 2006 for the treatment of diffuse large B-cell lymphoma (DLBCL) in combination with CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) or other anthracycline-based chemotherapy regimens in previously untreated patients, as well as in combination with methotrexate to reduce signs and symptoms in adult patients with moderately-to-severely active rheumatoid arthritis who have had an inadequate response to one or more tumor necrosis factor antagonist therapies.

Genentech and Biogen Idec co-market Rituxan in the United States, and Roche markets MabThera in the rest of the world, except Japan, where Rituxan is co-marketed by Chugai and Zenyaku Kogyo Co. Ltd. Rituxan has more than 960,000 patient exposures worldwide. For a copy of the Rituxan full prescribing information, including Boxed Warning, please call 1-800-821-8590 or visit www.gene.com .

FDA Approves Vectibix(TM) to Treat Patients with Metastatic Colorectal Cancer
Wednesday September 27, 4:47 pm ET  
First Entirely Human Anti-EGFr Antibody Approved by the FDA and Amgen's First Targeted Cancer Therapeutic


THOUSAND OAKS, Calif.--(BUSINESS WIRE)--Amgen (NASDAQ:AMGN - News) today announced that the U.S. Food and Drug Administration (FDA) has approved Vectibix(TM) (panitumumab) following priority review. Vectibix is the first entirely human monoclonal antibody for the treatment of patients with epidermal growth factor receptor- (EGFr) expressing metastatic colorectal cancer after disease progression on, or following fluoropyrimidine-, oxaliplatin-, and irinotecan- containing chemotherapy regimens.
ADVERTISEMENT


The FDA approval of Vectibix was based on a progression-free survival endpoint. Vectibix is the first anti-EGFr antibody shown to significantly improve progression-free survival in patients with metastatic colorectal cancer. Currently no data are available that demonstrate an improvement in disease-related symptoms or increased survival with Vectibix. Vectibix can be conveniently administered intravenously once every two weeks.

Vectibix is expected to be commercially available in early-to-mid October and will be priced at approximately 20 percent less than the other anti-EGFr antibody currently on the market.

"Vectibix is the first entirely human antibody for the treatment of colorectal cancer to be approved by the FDA. It provides another option for patients with metastatic colorectal cancer that have progressed on all available chemotherapy regimens," said J. Randolph Hecht, M.D., director of the UCLA Gastrointestinal Oncology Program and clinical professor of Medicine, UCLA David Geffen School of Medicine, Los Angeles. "In a large, randomized clinical trial, Vectibix has been shown to delay progression of disease compared to best supportive care."

Epidermal growth factor receptors are proteins that play an important role in cancer cell signaling. Vectibix is an entirely human IgG2 monoclonal antibody that binds with high affinity to EGF receptors. The goal of developing entirely human monoclonal antibodies is to offer effective targeted therapies with lessened risk of immune response against these agents.

"Our goal is to fulfill the promise of biotechnology to improve the way cancer is treated," said Willard Dere, M.D., chief medical officer and senior vice president of Global Development at Amgen. "The approval of Vectibix allows us to build on our strong foundation in supportive care and move forward with our comprehensive approach to helping patients in their fight against cancer."

"One out of 18 people in this country will develop colorectal cancer in their lifetime and 20 percent of colorectal cancers are found after the disease has spread to distant organs." said Amy Kelly, director and co-founder of the Colon Cancer Alliance. "That means that a person in the U.S. is diagnosed with colorectal cancer every four minutes, heightening the need for new therapeutic options such as Vectibix."

Marketing applications were simultaneously submitted to the European Medicines Agency (EMEA) in April 2006 and Health Canada, Australia and Switzerland in May 2006. Vectibix is being evaluated in ongoing clinical trials as both a monotherapy and in combination with other agents for the treatment of various types of cancer.

As described below, the Vectibix Prescribing Information includes warning language as part of evolving FDA labeling for the anti-EGFr class:

Dermatologic toxicities, related to Vectibix blockade of EGF binding and subsequent inhibition of EGF receptor-mediated signaling pathways, included but were not limited to dermatitis acneiform, pruritus, erythema, rash, skin exfoliation, paronychia, dry skin, and skin fissures. Dermatologic toxicities were reported in 89 percent of patients treated with Vectibix and were severe in 12 percent of patients. Severe dermatologic toxicities were complicated by infection, including sepsis, septic death, and abscesses requiring incisions and drainage. Vectibix may need to be withheld or discontinued for severe dermatologic toxicities.

Severe infusion reactions occurred with Vectibix in approximately 1 percent of patients. Severe infusion reactions were identified as anaphylactic reactions, bronchospasm, fever, chills, and hypotension. Although fatal infusion reactions have not been reported with Vectibix, they have occurred with other monoclonal antibody products. Severe infusion reactions require stopping the infusion and possibly permanently discontinuing Vectibix, depending on the severity and/or persistence of the reaction.

Other important safety information includes:

The most common adverse reactions to Vectibix were generally mild to moderate and included skin rash with variable presentations, paronychia, fatigue, abdominal pain, nausea and diarrhea. Hypomagnesemia occurred 6 weeks or longer after the initiation of Vectibix. In some patients, hypomagnesemia was associated with hypocalcemia.

About Colorectal Cancer

Colorectal cancer is the third most common cancer diagnosed in men and in women in the United States. The American Cancer Society estimated that about 146,940 new cases of colon cancer and 41,930 new cases of rectal cancer will be diagnosed in 2006. Colorectal cancer is the second leading cause of cancer death among men and women in the United States and Canada (after lung cancer). It has been estimated that 56,370 people will die from colorectal cancer in 2006. That means that one person in the United States dies of colorectal cancer every 9.3 minutes.

About Vectibix

Although EGF receptors normally help regulate the growth of many different cells in the body, these receptors also can stimulate cancer cells to grow. In fact, some cancer cells actually require signals mediated by EGF receptors for their survival. Residing on the surfaces of these tumor cells, EGF receptors are activated when naturally occurring proteins in the body, such as epidermal growth factor (EGF) or transforming growth factor alpha (TGF-alpha), bind to them. This binding changes the shape of the EGF receptors, which, in turn, triggers internal cellular signals that stimulate tumor cell growth. Vectibix binds to EGF receptors, preventing the natural ligands such as EGF and TGF-alpha from binding to the receptors and interfering with the signals that might otherwise stimulate growth and survival of the cancer cell.

FDA Approves REMICADE® (Infliximab) For Treatment Of Chronic Severe Plaque Psoriasis: Marks Major Milestone For Patients With High Disease Burden
Nearly Eight Out of 10 Patients Treated With REMICADE® (Infliximab) Achieved 75 Percent Improvement in Psoriasis at Week 10
Horsham, PA (September 27, 2006) – Centocor, Inc., announced today that the U.S. Food and Drug Administration (FDA) has approved REMICADE® (infliximab) for the treatment of adult patients with chronic severe (i.e., extensive and/or disabling) plaque psoriasis who are candidates for systemic therapy and when other systemic therapies are medically less appropriate. The recommended dose is an infusion of 5 mg/kg followed by additional doses at two and six weeks after the first infusion and then every eight weeks thereafter. In the Phase 3 clinical trial EXPRESS, eight out of 10 patients receiving REMICADE® 5 mg/kg induction therapy achieved 75 percent improvement in psoriasis as measured by Psoriasis Area Severity Index (PASI 75) by week 10. Similar results were seen with EXPRESS II, the second Phase 3 study. These results were maintained by every eight-week REMICADE® 5 mg/kg maintenance infusions at six months. The majority of patients who continued on this regimen achieved PASI 75 at week 50, the last visit in both studies. More than 1,200 patients participated in the two Phase 3 clinical trials.

"The rapidity and consistency with which REMICADE® can improve clearance of patients' skin is a major step forward for a patient population where persisting unmet needs in treatment exist," said Alice B. Gottlieb, M.D., Ph.D., dermatologist-in-chief, professor of Dermatology, Tufts-New England Medical Center, and pivotal U.S. study investigator. "As a researcher involved in the clinical investigation of REMICADE® for the treatment of psoriasis, I've seen first-hand its significant results in improving psoriasis in the majority of patients treated."

Psoriasis is an inflammatory disorder characterized by raised, inflamed, red lesions, or plaques, which can cause physical pain and emotional distress. It is estimated that as many as 7.5 million people in the U.S. have psoriasis1, which can present in various forms and can range from mild to severe and disabling. Centocor will expand its educational programs to help dermatologists and their patients achieve the benefits of REMICADE® and to help manage and minimize the potential risks of biologic therapies, like REMICADE®.

Data from two multi-center, randomized, double-blind, placebo-controlled trials – EXPRESS and EXPRESS II – served as the primary basis for approval. Both EXPRESS and EXPRESS II showed that a majority of patients treated with REMICADE® achieved clinically significant levels of skin clearance with induction and every eight-week maintenance therapy. At week 10 in EXPRESS, 80 percent of patients receiving REMICADE® 5 mg/kg achieved PASI 75 versus three percent of patients receiving placebo (P < 0.001). At week 10 in EXPRESS II, 75 percent of patients receiving REMICADE® 5 mg/kg achieved PASI 75 versus two percent of patients receiving placebo (P < 0.001).

During the controlled periods in EXPRESS and EXPRESS II, adverse events (AEs) occurred at a higher incidence in the REMICADE® groups compared with the placebo groups. In the EXPRESS study, there were more serious adverse events, including one fatal infection, in the REMICADE® group compared to placebo group. In the EXPRESS II study, serious AE rates were similar in the REMICADE® 5 mg/kg and placebo groups. The only clinically significant laboratory abnormalities that occurred more frequently in the REMICADE® groups compared with the placebo groups were elevated liver enzyme tests. AEs observed in these studies were generally consistent with those described in the prescribing information, including the risk of serious infections. Please see "Important Safety Information" below.

"New biologic treatment options are needed in our struggle to more effectively manage all patients with this lifelong, chronic condition, particularly those that have severe disease," said Alan Menter, M.D., chairman, Division of Dermatology, Baylor University Medical Center, and lead U.S. study investigator. "The approval of REMICADE® offers dermatologists a treatment option that has been clinically proven to rapidly and dramatically clear the skin of patients with a high disease burden."

Psoriasis is most commonly diagnosed between the ages of 20 and 30, striking in the prime of people's lives, and the extent of skin involvement varies from mild to severe and disabling. People with severe psoriasis may have large areas of their body covered by lesions, which may crack and bleed. The pain and embarrassment associated with such skin lesions may prevent people from participating in social and work-related activities, and the physical and mental effects of psoriasis have been compared to those of other chronic illnesses such as rheumatoid arthritis, hypertension, heart disease, diabetes and depression. Skin lesions associated with psoriasis often result in feelings of sadness, despair, guilt and anger, as well as in low self-esteem. A person’s sense of self-worth can be affected, and in some cases, this emotional turmoil can lead to depression.

"The severity of psoriasis is something that can often be misunderstood. Imagine having psoriatic plaques on the soles of your feet, which makes walking painful and difficult. Or, imagine going through life with your face and arms covered in psoriasis and how that would make you feel. These are just a few examples of what some patients must contend with," said Gail Zimmerman, president and CEO, National Psoriasis Foundation. "The approval of REMICADE® is a much needed addition for patients with severe psoriasis."

REMICADE® is the first and only anti-TNF-alpha treatment to receive 13 FDA approvals across inflammatory diseases in gastroenterology, rheumatology and dermatology, and has now been used to treat more than 800,000 patients worldwide, more than all other anti-TNF agents combined. REMICADE® is an advanced biologic treatment for chronic severe plaque psoriasis, requiring as few as six treatments a year after an initial three treatments.

About EXPRESS

The European Infliximab for Psoriasis [REMICADE®] Efficacy and Safety Study (EXPRESS) was a Phase 3, multi-center, randomized, double-blind, placebo-controlled trial that evaluated the safety and efficacy of REMICADE® induction and maintenance therapy in 378 adult patients with chronic, stable plaque psoriasis involving at least 10 percent BSA, a minimum PASI score of 12 and who were candidates for phototherapy or systemic therapy. Patients received either REMICADE® 5 mg/kg or placebo administered at weeks zero, two and six, followed by maintenance treatment every eight weeks. The REMICADE® group continued on maintenance treatments every eight weeks. Beginning at week 24, patients randomized to the placebo group were crossed over to receive REMICADE® therapy through week 46.  

In EXPRESS, through week 24, AEs occurred at a higher incidence in the REMICADE® group (82 percent) compared with the placebo group (71 percent). The only clinically significant laboratory abnormalities that occurred more frequently in the REMICADE® group compared with the placebo group were elevated liver enzyme tests. There were more serious AEs (six percent), including one fatal infection, in the REMICADE® group than in the placebo group (three percent). AEs observed were generally consistent with those described in the prescribing information, including information regarding serious infections. Please see "Important Safety Information" below.

About EXPRESS II

The Evaluation of Infliximab for Psoriasis in a [REMICADE®] Efficacy and Safety Study (EXPRESS II) was a Phase 3, multi-center, randomized, double-blind, placebo-controlled trial that evaluated the safety and efficacy of REMICADE® in 835 adult patients with chronic, stable plaque psoriasis involving at least 10 percent BSA, a minimum PASI score of 12 and who were candidates for phototherapy or systemic therapy. Patients were randomized to induction doses of REMICADE® 3 mg/kg or 5 mg/kg or placebo at weeks zero, two and six. Patients in the active induction treatment groups were randomized again at week 14 to receive either scheduled or "as needed" maintenance treatment at the same dose administered during the induction phase. Patients in the placebo group were crossed over at week 16 to receive REMICADE® 5 mg/kg at weeks 16, 18 and 22, then every eight weeks through week 46.  

In EXPRESS II, through week 14 (the placebo-controlled period), AEs occurred at a higher incidence in the REMICADE® groups (63 percent and 69 percent with 3 mg/kg and 5 mg/kg, respectively), compared with the placebo group (56 percent). The only clinically significant laboratory abnormalities that occurred more frequently in the REMICADE® group compared with the placebo group were elevated liver enzyme tests. Serious AEs occurred at rates of two percent in the placebo group, three percent in the 5 mg/kg group and one percent in the 3 mg/kg group. AEs observed were generally consistent with those described in the prescribing information, including information regarding serious infections. Please see "Important Safety Information" below.

About Psoriasis

Psoriasis is a chronic, immune-mediated disease, which results when skin cells over-produce and accumulate on the surface causing red, scaly plaques that may itch and bleed. This chronic inflammation is driven in part by tumor necrosis factor alpha, or TNF-alpha, a cytokine involved in the body's normal immune response. TNF-alpha is found at increased levels in psoriatic plaques and plays a crucial part in their formation and continued existence. It is estimated that two percent of the U.S. population has psoriasis, and about 30 percent of people with psoriasis have cases that are considered moderate to severe.

About REMICADE®

REMICADE® is the global market leader among anti-tumor necrosis factor alpha (TNF-alpha) therapies and is the only anti-TNF-alpha treatment approved in three different therapeutic areas: gastroenterology, rheumatology and dermatology. REMICADE® has demonstrated broad clinical utility in Crohn's disease (CD), rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), ulcerative colitis (UC), pediatric Crohn's disease (PCD) and psoriasis (PsO). The safety and efficacy of REMICADE® have been well established in clinical trials over the past 14 years and with more than 800,000 patients treated worldwide through commercial experience.

In the U.S., REMICADE®, in combination with methotrexate, is indicated for reducing signs and symptoms, inhibiting the progression of structural damage and improving physical function in patients with moderately to severely active RA. REMICADE® is the only biologic indicated for reducing signs and symptoms and inducing and maintaining clinical remission in adult and pediatric patients with moderately-to-severely active CD who have had an inadequate response to conventional therapy. REMICADE® is also indicated for reducing the number of draining enterocutaneous and rectovaginal fistulas and maintaining fistula closure in patients with fistulizing CD. In December 2004, REMICADE® was approved for reducing signs and symptoms in patients with active AS. In May 2005, REMICADE® was approved for reducing signs and symptoms of active arthritis in patients with PsA. Additionally, in September 2005, REMICADE® was approved for reducing signs and symptoms, achieving clinical remission and mucosal healing and eliminating corticosteroid use in patients with moderately to severely active UC who have had an inadequate response to conventional therapy. This approval makes REMICADE® the first and only biologic approved for the treatment of moderate to severe UC. In addition, on May 19, 2006, REMICADE® was approved for reducing signs and symptoms and inducing and maintaining clinical remission in pediatric patients with moderately to severely active Crohn's disease who have had an inadequate response to conventional therapy. This approval establishes REMICADE® as the first and only biologic therapy approved for the treatment of PCD.

REMICADE® is unique among available anti-TNF biologic therapies. Unlike self-administered therapies that require patients to inject themselves frequently, REMICADE® is the only anti-TNF biologic administered directly by caregivers in the clinic or office setting. In RA (3 mg/kg), CD (5 mg/kg), PsA (5 mg/kg), UC (5 mg/kg), PCD (5 mg/kg), and PsO (5 mg/kg), REMICADE® is a two-hour infusion administered every eight weeks, following a standard induction regimen that requires treatment at weeks zero, two and six. As a result, REMICADE® patients may require as few as six treatments each year. In AS (5 mg/kg), REMICADE® is a two-hour infusion administered every six weeks, following a standard induction regimen that requires treatment at weeks zero, two and six.

Important Safety Information

There are reports of serious infections, including tuberculosis (TB), sepsis and pneumonia. Some of these infections have been fatal. Tell your doctor if you have had recent or past exposure to people with TB. Your doctor will evaluate you for TB and perform a TB test. If you have latent (inactive) TB, your doctor should begin TB treatment before you start REMICADE®. REMICADE® can lower your ability to fight infections, so if you are prone to or have a history of infections, or develop any signs of an infection such as fever, fatigue, cough, flu or warm, red or painful skin while taking REMICADE®, tell your doctor right away. Also, tell your doctor if you are scheduled to receive a vaccine or if, you have lived in a region where histoplasmosis or coccidioidomycosis is common.

Reports of a type of blood cancer called lymphoma in patients on REMICADE® or other TNF blockers are rare but occur more often than expected for people in general. People who have been treated for rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, or plaque psoriasis for a long time, particularly those with highly active disease, may be more prone to develop lymphoma. Cancers, other than lymphoma, have also been reported. Children and young adults who have been treated for Crohn's disease with REMICADE® have developed a rare type of lymphoma that often results in death. These patients also were receiving drugs known as azathioprine or 6-mercaptopurine. If you take REMICADE® or other TNF blockers, your risk for developing lymphoma or other cancers may increase. You should also tell your doctor if you have had or develop lymphoma or other cancers or if you have a lung disease called chronic obstructive pulmonary disease (COPD).

Many people with heart failure should not take REMICADE®; so prior to treatment you should discuss any heart condition with your doctor. Tell your doctor right away if you develop new or worsening symptoms of heart failure (such as shortness of breath, swelling of your ankles or feet or sudden weight gain).

Reactivation of hepatitis B virus has been reported in patients who are carriers of this virus and are taking TNF blockers, such as REMICADE®. Some of these cases have been fatal. Tell your doctor if you know or think you may be a carrier of hepatitis B virus or if you experience signs of hepatitis B infection, such as feeling unwell, poor appetite, tiredness, fever, skin rash and/or joint pain.

There have been rare cases of serious liver injury in people taking REMICADE®, some fatal. Tell your doctor if you have liver problems and contact your doctor immediately if you develop symptoms such as jaundice (yellow skin and eyes), dark brown urine, right-sided abdominal pain, fever or severe fatigue.  

Blood disorders have been reported, some fatal. Tell your doctor if you develop possible signs of blood disorders such as persistent fever, bruising, bleeding or paleness while taking REMICADE®. Nervous system disorders have also been reported. Tell your doctor if you have or have had a disease that affects the nervous system, or if you experience any numbness, weakness, tingling, visual disturbances or seizures while taking REMICADE®.

Allergic reactions, some severe, have been reported during or after infusions with REMICADE®. Signs of an allergic reaction include hives, difficulty breathing, chest pain, high or low blood pressure, swelling of face and hands and fever or chills. Tell you doctor if you have experienced a severe allergic reaction. The most common side effects of REMICADE® are: respiratory infections, such as sinus infections and sore throat, headache, rash, coughing and stomach pain.

Please read the Medication Guide for REMICADE® and discuss it with your doctor.

Hoffnung auf den Nobelpreis-Blockbuster
von Martin Virtel

Die mit dem Nobelpreis für Medizin ausgezeichnete Entdeckung hat bereits zu einem Biotech-Gründungsboom geführt. Erste Medikamente werden derzeit an Menschen getestet.

Die Amerikaner Andrew Fire und Craig Mello hatten 1997 bei Fadenwürmern einen Mechanismus entdeckt, mit dem Zellen ihre eigenen Gene und die von Viren blockieren. Sie nutzen dazu kleine Schnippsel aus RNA, einer nahen Verwandten der Erbsubstanz DNA. Es stellte sich heraus, dass die so genannte RNA-Interferenz beim Menschen genau so wie beim Wurm funktioniert.

Krankheitserreger könnten also mit Blockade-Molekülen ausgeschaltet, krank machende Erbinformationen neutralisiert werden - so die Hoffnung von Investoren, die in den acht Jahren seit der Veröffentlichung von Fires und Mellos Milliarden Dollar in die Suche nach RNA-Interferenz-Medikamenten investiert haben. "Das kommerzielle Potenzial dieser Entdeckung ist enorm. Ich glaube schon, dass sich Craig und Fire eine ganze Reihe interessanter Patente gesichert haben", sagte Hans Jörnvall vom Nobelkomitee der Nachrichtenagentur dpa.

Pharmakonzerne wie Merck, GlaxoSmithKline und Novartis gehören mit zu den Investoren in die Forschung. Medikamente sind noch keine auf dem Markt, die Hoffnungen sind trotzdem ungetrübt: "Wir glauben, dass RNA-Interferenz eine grundlegende Technologie für eine breite Palette von Anwendungen ist", sagt Douglas Chow, Analyst der auf Biotech spezialisierten Investmentbank Caris in New York. "Unser Ausblick für Sirna und Alnylam ist positiv."


Beide Unternehmen sind an der Nasdaq notiert und erproben bereits RNA-Interferenz-Medikamente an Menschen. Dabei wird die RNA per Spritze oder Pille an den Krankheitsherd gebracht. Sirna hat ein RNA-basiertes Mittel gegen eine seltene Art der Altersblindheit entwickelt: Gene, die dafür sorgen, dass die Netzhaut mit Blutgefäßen zuwächst, werden durch das Mittel ausschaltet. Alnylam testet ein Medikament gegen das Respiratory Syncytial Virus, einen häufigen und für Erwachsene harmlosen Erreger von Atemwegserkrankungen.

Das Virus nutzt RNA als Träger für die eigenen Erbinformationen, deswegen kann das aus RNA hergestellte Medikament das Erbgut des Erregers direkt blockieren. Die Hoffnung ist, den Mechanismus eines Tages auch gegen zwei sehr viel verheerendere RNA-Viren einzusetzen: den Aids-Erreger HIV und das Grippe-Virus. "Gegen Influenza gibt es sehr gute Resultate, allerdings erst im Reagenzglas und bei Tieren", sagt Chow.
Erste Tests bei Menschen erfolgreich

Alle diese Ansätze gehen allerdings davon aus, dass der Patient ständig RNA-Mittel erhält. Eleganter wäre es, wenn ein kranker oder von einem Virus befallener Kärper selbst in die Lage versetzt wird, die heilenden Erbgutschnippsel herzustellen. "Diese systemische Anwendung von RNAi ist die Hoffnung für die Zukunft", sagt Chow. Allerdings birgt diese Anwendung auch neue Risiken: Ein Versuch an Mäusen zeigte, dass sich Zellen unter Umständen selbst zugrunde richten, wenn sie durch Medikamente allzu stark zur Produktion von Blockade-RNA angeregt werden.

FDA Approves Avastin in Combination With Chemotherapy for First-Line Treatment of Most Common Type of Lung Cancer


-- Avastin Is First Therapy to Extend Survival Beyond One Year in Patients with Advanced Non-Small Cell Lung Cancer  --


-- Genentech Expands Patient Access Programs to Include Annual Expenditure Cap for Avastin  --


South San Francisco, Calif. --  11. Oktober 2006 --  Genentech, Inc. (NYSE: DNA) announced today that the U.S. Food and Drug Administration (FDA) has approved Avastin® (bevacizumab) to be used in combination with carboplatin and paclitaxel chemotherapy for the first-line treatment of patients with unresectable, locally advanced, recurrent or metastatic non-squamous, non-small cell lung cancer (NSCLC), the most common type of lung cancer. The approval is based on a Phase III study (E4599) that showed Avastin in combination with chemotherapy resulted in a 25 percent improvement in overall survival compared to chemotherapy alone (based on a hazard ratio of 0.80).
"Bevacizumab, in combination with chemotherapy, is the first therapy in 10 years to improve on standard first-line treatment for advanced lung cancer and the first FDA-approved therapy ever to extend survival for these patients beyond one year in a large, randomized clinical study," said Alan Sandler, M.D., director of Medical Thoracic Oncology at Vanderbilt-Ingram Cancer Center in Nashville, Tenn., and lead investigator on the E4599 trial. "With this survival benefit, bevacizumab represents an important therapy for many advanced lung cancer patients fighting this difficult disease."

"Lung cancer is responsible for more than one-third of all U.S. cancer deaths, killing more people than breast, prostate, colon, liver and kidney cancers combined," said Laurie Fenton, president of the Lung Cancer Alliance in Washington, D.C. "The approval of Avastin plus chemotherapy is a significant stride in the right direction, and we are pleased that Genentech continues to make lung cancer a priority."

About E4599
The FDA approval for this new indication was based on results from E4599, a randomized, controlled, multi-center trial that enrolled 878 patients with unresectable, locally advanced, recurrent or metastatic non-squamous NSCLC. Patients with mixed histology were excluded if the predominant cell type was squamous. Results showed that patients receiving Avastin plus paclitaxel and carboplatin chemotherapy had a 25 percent improvement in overall survival, the trial's primary endpoint, compared to patients who received paclitaxel and carboplatin alone (based on a hazard ratio of 0.80). One-year survival was 51 percent in the Avastin plus chemotherapy arm versus 44 percent in the chemotherapy-alone arm. Median survival of patients treated with Avastin plus chemotherapy was 12.3 months, compared to 10.3 months for patients treated with chemotherapy alone.

The E4599 trial was sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health, under a Cooperative Research and Development Agreement between NCI and Genentech. The trial was conducted by a network of researchers led by the Eastern Cooperative Oncology Group (ECOG).

E4599 Safety Analysis
The most common Grade 3-5 (severe) adverse events in Study E4599 seen in Avastin-treated patients were neutropenia (low white blood cell count), fatigue, hypertension (high blood pressure), infection and hemorrhage.

In Study E4599, the rate of pulmonary hemorrhage requiring medical intervention for the paclitaxel and carboplatin plus Avastin arm was 2.3 percent (10/427), compared to 0.5 percent (2/441) for the paclitaxel and carboplatin-alone arm. There were seven deaths due to pulmonary hemorrhage reported by investigators in the paclitaxel and carboplatin-plus Avastin arm, as compared to one in the paclitaxel and carboplatin-alone arm.

In previous clinical experience with Avastin in combination with paclitaxel and carboplatin in NSCLC, patients with a specific type of NSCLC called squamous cell carcinoma had a higher risk of experiencing life-threatening or fatal pulmonary bleeding. Squamous cells are a particular kind of cell that form in the lining of the air ducts in the lung. Because of the risk of bleeding attributed to this population, patients with NSCLC classified as predominantly squamous histology were not included in the E4599 trial.

About the New Avastin Annual Expenditure Cap and Genentech's Access to Care Programs
Genentech also announced today that the company plans to initiate a first-of-its-kind program to cap the overall expense of Avastin to $55,000 per year per eligible patient for any FDA-approved indication. The program will be available for eligible patients regardless of whether they are insured. The company plans to launch the new program in January 2007. In addition, the company announced that it has doubled its contribution to independent charities that provide co-pay assistance to a total of $50 million.

"The clinical development program that led to Avastin's three FDA approvals suggested dose and duration vary depending on tumor type," said Arthur D. Levinson, Ph.D., Genentech's chairman and chief executive officer. "The new expenditure cap on Avastin is a step Genentech is taking to address this variability in current and future FDA-approved indications. This new program, along with the increased contribution to independent charities that provide co-pay assistance to patients, continues our 20-year history of commitment to patient access."

The price of Avastin was established in February 2004 upon the FDA approval of the drug for the treatment of first-line colorectal cancer in combination with 5-FU based chemotherapy. At that time, the monthly price of Avastin was set below the standard of care chemotherapy for metastatic colorectal cancer at approximately $4,400.

In advanced lung cancer, a higher dose of Avastin is indicated. This dose was based on clinical data from a randomized dose-ranging Phase II study of Avastin in combination with chemotherapy. Based on this trial, ECOG and NCI selected the higher dose for the pivotal Phase III trial in NSCLC. The typical monthly cost of Avastin at this dose is approximately $8,800 and, based on median progression-free survival as measured in the E4599 trial, the average cost per course of therapy in NSCLC is approximately $56,000.

Avastin is covered by most insurers and Medicare for its approved indications. Genentech's donation to independent co-pay charities helps provide assistance to eligible patients with higher co-pay burdens. For eligible uninsured patients, the Genentech Access to Care Foundation (GATCF) provides Avastin for free.

Genentech has provided more than $850 million in free drug to patients since 1990. In 2005 alone, GATCF supported over 18,000 patients by providing approximately $200 million of free product. To learn more about the GATCF, independent charities that provide co-pay assistance to patients and potential financial assistance options, patients can speak with an Alternative Funding Specialist from Genentech's Single Point of Contact (SPOC) group by calling 888-249-4918 or visiting www.SPOConline.com.

About Lung Cancer
According to the American Cancer Society, lung cancer is the single largest cause of cancer deaths among men and women in the U.S. and is responsible for nearly 30 percent of cancer deaths in this country. The American Cancer Society estimates that more than 170,000 Americans will be diagnosed with lung cancer this year, and 162,000 Americans will die of the disease this year. NSCLC is the most common type of lung cancer.

About Avastin
Avastin, in combination with intravenous 5-fluorouracil (FU)-based chemotherapy, is indicated for first- or second-line treatment of patients with metastatic carcinoma of the colon or rectum; and in combination with carboplatin and paclitaxel for the first-line treatment of patients with unresectable, locally advanced, recurrent or metastatic non-squamous, non-small cell lung cancer (NSCLC). For full prescribing information and boxed warnings on Avastin and information about angiogenesis, visit www.gene.com. For more information on Avastin, visit www.avastin.com.

The FDA first approved Avastin on February 26, 2004, as a first-line treatment for metastatic colorectal cancer in combination with intravenous 5-FU-based chemotherapy. The National Comprehensive Cancer Network recommends Avastin plus chemotherapy as a standard treatment for the first- and second-line treatment of metastatic colorectal cancer and as a first-line treatment of advanced non-squamous NSCLC.

Avastin Safety
The most serious adverse events associated with Avastin across all trials were gastrointestinal perforation, wound healing complications, hemorrhage, arterial thromboembolic events, hypertensive crisis, reversible posterior leukoencephalopathy syndrome (RPLS), neutropenia and infection, nephrotic syndrome and congestive heart failure. The most common adverse events in patients receiving Avastin were asthenia, pain, abdominal pain, headache, hypertension, diarrhea, nausea, vomiting, anorexia, stomatitis, constipation, upper respiratory infection, epistaxis, dyspnea, exfoliative dermatitis and proteinuria.

About the Avastin Development Program
Based on data showing that VEGF may play a broad role in a range of cancers, Genentech is pursuing a broad development program for Avastin that currently includes 130 clinical trials across 25 different types of cancer. Avastin is being evaluated in Phase III clinical trials for its potential use in adjuvant and metastatic colorectal, renal cell (kidney), breast, non-small cell lung, prostate and ovarian cancers. Avastin is also being evaluated in earlier stage trials as a potential therapy in a variety of solid tumor cancers and hematologic malignancies. For further information about Avastin clinical trials, please call 888-662-6728.

About VEGF and Tumor Angiogenesis
Genentech is a leader in research and product development in the area of angiogenesis, the process by which new blood vessels are formed. The link between angiogenesis and cancer growth has been discussed by many researchers for decades; however it was not until 1989 that a key growth factor influencing the process, vascular endothelial growth factor (VEGF), was discovered by Napoleone Ferrara, M.D., a staff scientist at Genentech. Ferrara and his team at Genentech cloned VEGF, providing some of the first evidence that a specific angiogenic growth factor existed. This research was published in the journal Science in 1989. Ferrara then created a mouse antibody to this protein.

In 1993, in a study published in the journal Nature, Ferrara and his team demonstrated that the antibody directed against VEGF could suppress angiogenesis and tumor growth in preclinical models, providing compelling evidence that VEGF can play an important role in tumor growth. Clinical studies with a humanized version of the antibody, Avastin, began in 1997.

About Genentech BioOncology
Genentech is committed to changing the way cancer is treated by establishing a broad oncology portfolio of innovative, targeted therapies with the goal of improving patients' lives. The company is the leading provider of anti-tumor therapeutics in the United States. Genentech is conducting clinical development programs for Rituxan® (Rituximab), Herceptin® (Trastuzumab), Avastin® (bevacizumab), and Tarceva® (erlotinib), and markets all four products in the United States, either alone (Avastin and Herceptin) or with Biogen Idec Inc. (Rituxan) or OSI Pharmaceuticals, Inc. (Tarceva).

The company has a robust pipeline of potential oncology therapies with a focus on four key areas: angiogenesis, apoptosis (i.e., programmed cell death), the HER pathway, and B-cell biology. An investigational antibody directed at the HER pathway is currently in Phase II trials. In early development are a small molecule directed at the hedgehog pathway and an investigational agent targeting apoptosis.

Founded 30 years ago, Genentech is a leading biotechnology company that discovers, develops, manufactures and commercializes biotherapeutics for significant unmet medical needs. A considerable number of the currently approved biotechnology products originated from or are based on Genentech science. Genentech manufactures and commercializes multiple biotechnology products and licenses several additional products to other companies.

MEDX entwickelt sich genau so, wie ich mir das vorgestellt habe. Solange jederzeit eine FDA Zulassung oder positive Testresultate ins Haus flattern können, gehts Richtung Norden.  
Spezielles Augenmerk ist bei den Produkten die mit JNJ zusammen entwickelt wurden angebracht. Solche Riesenkonzerne lassen sich Umsatzmillionen nicht gerne entgehen.
Die Barreserven und die Beteiligung an Genmab wirken sich äusserst positiv auf das Risikopotential aus.

Die Produkte CNTO 148 und CNTO 1275 werden zusammen mit Centocor entwickelt, dies ist meines Wissens eine Tochterfirma von JNJ.
(Jüngstes Bsp. einer solchen Übernahme: Eli Lilly - ICOS)

Glaube aber nicht, dass es bei MEDX zu einer Übernahme kommt, hoffe ich zumindest. Ich sehe das Kurspotential im Alleingang am grössten.

Genmab ist heute wieder kräftig am steigen, die Story scheint im Moment einfach zu stimmen.

Big Pharma ist unter Druck, Pfizer, Novartis etc. performen negativ. Auf der Gegenseite gehören innovative Firmen mit modernen Pipelines wie Genmab und Actelion zu den Gewinnern.
Innovation der Pipeline und deren Wertschöpfungspotential ist wohl eine der wichtigsten Bewertungsgrundlagen in diesem Sektor.
Medarex ist mit seiner sehr diversifizierten Pipeline gut gerüstet für die Zukunft.
Bedenkt man, dass Pfizer allein heute rund 30 Milliarden USD an Marktkapitalisierung verliert aufgrund eines erfolglosen Projektes in der Pipeline und stellt diese Zahl der Marktkapitalisierung von Medarex gegenüber, so haben wir hier grob gesehen ein sehr gutes Chance Risiko Verhältnis.

Die ca. 20% die Medarex an Genmab hält, könnten teuer werden :-).
Auffällige Kursentwicklung ist auch bei Actelion zu vermerken...
Und Novartis sieht die Zukunft der Pipeline auch in der Biotechnologie...

Die Anwendungen, die vor dem Jahr 2000 den grossen Hype bei Biotech Aktien auslösten, werden jetzt marktreif oder auch nicht (z.B. Nuvelo). Die Wertschöpfung aus den getätigten Investitionen wird erst jetzt wirksam und da könnte der eine oder andere Stern am Himmel aufgehen.
(Wäre schön, bei einer solchen Story dabei zu sein)

Weitere Beobachtung: Illumina gibt vollgas, ebenso Sequenom. Die DNA Analysen werden in Zukunft viele Bereiche unseres täglichen Lebens stark beeinflussen. (Nahrungsmittelkontrolle, pränatale nichtinvasive Diagnostik, Medizin, Diagnostik, Wirkstoffentwicklung, Sicherheit (DNA-Datenbank), Agrartechnik (Saatgut, Zucht) etc...)

Ein Kursplus von 30% war drin. GSK hat sich bei Genmab eingekauft.
Die Kursreaktion bei Medarex fiel bisher eher gering aus. Die Zeit von Medarex wird aber noch kommen. Für Roche wird jetzt Genmab nicht mehr so interessant sein, daher rücken andere Titel an diese Stelle.
Auch Pfizer und Novartis müssen sich in der Antikörper Technologie engagieren. Pfizer hat bereits den Vertrag mit Morphosys verlängert und von Novartis erwarte ich auch ein grösseres Engagement in diesem Segment.
Die nächsten zwei Jahre werden für Medarex die erfolgreichsten, geht man davon aus, dass 70% der PH III Entwicklungen die Marktzulassung erhalten und viele der PH I&II den Sprung in eine höhere Phase schaffen.
Auch bei der öffentlichen Sicherheit ist MEDX mit Valortim in einem grossen Markt tätig, hoffen wir aber, dass wir nie davon Gebrauch machen müssen. (moral hazard) Jedoch genügen hier schon kleine Angstmeldung um ins Rampenlicht zu rücken. (vgl. Tamiflu)

Gelingt der Durchbruch mit einem der PhIII Medikamente werden wir ein ähnliches Szenario wie bei GPC erleben. Die Spekulanten werden sich auf diesen Titel stürzen. Ein Erfolg würde auf einen Schlag die ganze Pipeline aufwerten und das bedeutet im Fall von Medarex über 30 Projekte.

Press ReleaseSource: Seattle Genetics, Inc.

Genentech and Seattle Genetics Announce Exclusive Global Licensing Agreement for Development and Commercialization of SGN-40
Monday January 8, 7:30 am ET

Seattle Genetics to Hold Conference Call Today at 4:30 p.m. ET

SOUTH SAN FRANCISCO, Calif. & BOTHELL, Wash.--(BUSINESS WIRE)--Genentech (NYSE: DNA - News) and Seattle Genetics, Inc. (Nasdaq: SGEN - News) today announced that they have entered into an exclusive worldwide license agreement for the development and commercialization of SGN-40. SGN-40 is a humanized monoclonal antibody currently in Phase I and Phase II clinical trials for multiple myeloma, chronic lymphocytic leukemia and non-Hodgkin's lymphoma.

Under the terms of the agreement, Seattle Genetics will receive an upfront payment of $60 million, potential milestone payments exceeding $800 million and escalating double-digit royalties on annual net sales of SGN-40. The milestone payments, which are dependent upon clinical and regulatory events across multiple disease indications worldwide, as well as attainment of certain annual net sales levels, include $20 million in committed payments during the first two years of the agreement. Genentech will fund future research, development, manufacturing and commercialization costs. Seattle Genetics will continue certain Phase I and Phase II clinical trials and development activities, the costs of which will be reimbursed by Genentech. Seattle Genetics also has an option for co-promotion rights on SGN-40 in the U.S. The completion of the agreement may be subject to Hart-Scott-Rodino approval under United States antitrust laws and customary closing conditions.

"This alliance enables us to accelerate and expand development of SGN-40 while we continue to advance our other promising clinical and preclinical development programs," said Clay B. Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. "Genentech's oncology development expertise, commercial leadership and history of successful strategic alliances make it an ideal collaborator to bring the potential benefits of SGN-40 to patients."

"We are very interested in the encouraging activity of SGN-40 observed in early clinical trials and we look forward to developing this antibody with Seattle Genetics, in addition to continuing our ongoing collaboration on antibody-drug conjugates," said Hal Barron, M.D., senior vice president, Development and chief medical officer for Genentech. "SGN-40 supports our commitment to developing new hematology therapeutics that may provide novel treatment approaches for a variety of serious hematologic diseases."

About SGN-40

SGN-40 is a humanized monoclonal antibody that targets the CD40 antigen, which is highly expressed on most B lineage hematologic malignancies including non-Hodgkin's lymphoma, multiple myeloma and chronic lymphocytic leukemia. CD40 is also found on many types of solid tumors, including bladder, renal and ovarian cancer, and may play a role in immunologic diseases.

Positive Phase I data were reported last month at the annual meeting of the American Society of Hematology demonstrating that SGN-40 is well tolerated and induces objective antitumor activity in patients with relapsed or refractory non-Hodgkin's lymphoma. Based on these results, Seattle Genetics initiated a single-agent Phase II study designed to assess the antitumor activity, tolerability and pharmacokinetic profile of SGN-40 in patients with relapsed or refractory diffuse large B-cell lymphoma in December 2006. In addition, SGN-40 is being evaluated in Phase I clinical trials for relapsed or refractory multiple myeloma and chronic lymphocytic leukemia.

Conference Call Details

Seattle Genetics' management will host a conference call and webcast to further discuss the agreement. The event will be held today at 1:30 p.m. Pacific Time (PT); 4:30 p.m. Eastern Time (ET). The live event will be available from the Seattle Genetics website at http://www.seattlegenetics.com, under the News and Investor Information section, or by calling (800) 218-8862 (domestic) or (303) 262-2175 (international).

ich bin deiner Meinung, nur sollte der Kurs Medx. ca,40 € sein, dann wäre mir eine Übernahme egal duch wen. Aber im allgemeinen Bio-Aufschwung ist wohl nichts unmöglich.

Eine DER AKTIONÄR empfehlung...

Kommt die ASCO-Hausse?

Das weltweit wichtigste Treffen der Krebsforscher steht ins Haus. Anleger beobachten gespannt die Aktienkurse von Medikamentenentwicklern. Welche Papiere können profitieren?

Alle Jahre wieder treffen sich in den USA die wichtigsten Krebsforscher aus aller Welt, um die Ergebnisse ihrer Forschungs- und Entwicklungsarbeit der Öffentlichkeit vorzustellen und die Resultate im Kreise der Kollegen zu diskutieren. Zu der Konferenz, die in diesem Jahr vom 1. bis zum 5. Juni in Chicago stattfindet, lädt alljährlich die American Society of Clinical Oncology, kurz ASCO.

Auch zahlreiche börsennotierte Unternehmen präsentieren sich beim ASCO-Meeting. Und nicht selten hat die Konferenz in den letzten Jahren für steigende Kurse gesorgt. Bestes Beispiel: Der heute weltgrößte Biotech-Konzern Genentech veröffentlichte 2003 beim ASCO-Meeting erstmals ausführliche Daten zu seinem heutigen Blockbuster-Krebsmedikament Avastin – und bereitete damit den Boden für den beispiellosen Aufstieg der letzten Jahre, durch den das Unternehmen aus South San Francisco dem Platzhirschen Amgen den Rang ablief.
Medarex - indirekter Profiteur?

Die Aktie von Medarex ist eine laufende AKTIONÄRS-Empfehlung. Seit das Papier des Anikörper-Spezialisten im September 2006 vorgestellt wurde, hat es bereits rund 22 Prozent zugelegt. Damit dürfte das Potenzial aber noch lange nicht ausgereizt sein. Kurzfristig könnte das ASCO-Meeting als Katalysator dienen. Denn hier stellt der Pharmakonzern Pfizer Daten aus einer Phase-III-Studie mit dem Krebsantikörper Ticilimumab vor. Fallen diese gut aus, würde Medarex, das den experimentellen Wirkstoff entwickelt und auslizenziert hat, davon gleich in doppelter Hinsicht profitieren. Positive Ergebnisse würden den Antikörper, der unter anderem gegen sogenannte Melanome eingesetzt werden soll, der Markteinführung ein gehöriges Stück näher bringen. Und beim Verkauf des Medikamentes wird Medarex ordentlich mitverdienen. Schätzungsweise 15 Prozent des Umsatzes – und der dürfte mindestens im hohen dreistelligen Millionbereich liegen – wandern in die Kasse des Biotech-Unternehmens. Zudem entwickelt Medarex einen ähnlichen Antikörper in Eigenregie. Positive Studiendaten dürften das Vertrauen der Investoren in den Erfolg des Medarex-Projektes nachhaltig stärken. Und Vertrauen ist bekanntlich die beste Basis für steigende Kurse.
Celgene - immer noch kaufenswert

Ich spekuliere stark darauf, dass die Daten zu diesen potentiellen Multimilliarden-Blockbustern (Ipilimumab/Ticilimumab) positiv sein werden.

Aber wie immer ist das die Crux bei immunmodulierenden Therapien, man weiß nie was in verblindeten Phase III-Studien dann wirklich im Vergleich zu den teils offenen Phase IIs herauskommt.

Und wie man bei Dendreon gesehen hat kann sich auch ein Feuerstein irren. Biotech ist oft ein recht unklakulierbares Investment.

Wie gesagt, ich spekuliere voll darauf, dass MEDX gute Daten vorlegen wird. Monoklonale Antikörper sind inzwischen eine anerkannte Klasse von Medikamenten

Gezielte Wirkung im Kampf gegen Tumore
Erfolg in kleinen Schritten: Wissenschaftler sind weiteren Schwachstellen der Tumoren auf der Spur

Krebs

Neue Erkenntnisse über die Entstehung von Tumoren erleichtern das Entwickeln individueller Krebstherapien. Impfungen sollen den Ausbruch der Krankheit künftig verhindern.

Ein Lächeln umspielt James Watsons Lippen. Die wachen Augen des 79-Jährigen Pioniers der Genforschung fixieren freundlich, aber fest die Forscher und Journalisten, die das US-Biotech-Unternehmen 454 Life Sciences im texanischen Houston eingeladen hat. Watson ist eine Legende, seit er 1953 zusammen mit Francis Crick die Struktur der DNA entschlüsselte, der Erbsubstanz jeglichen Lebens.

Jetzt sorgt er für einen neuen Meilenstein in der Genforschung: Forscher des Biotech-Unternehmens 454 haben für knapp eine Million Dollar in zwei Monaten Watsons komplettes Erbgut entschlüsselt. „Ich bin so aufgeregt, mein Genom zu sehen“, ruft Watson in den Saal. Er will es nicht für sich haben, sondern der Wissenschaft geben. Die Daten sollen den Forschern helfen, die Entstehung von Krankheiten aufzuklären und sie zu heilen. Watsons Auftritt ist ein Protest gegen die vielen gesetzlichen Einschränkungen bei der Freigabe von Genomen. „Die werden bewacht, als handele es sich um nukleare Waffen.“

Wie Watson hat auch Craig Venter sein Erbgut der Allgemeinheit gestiftet. Der Gründer von Celera hat die Entschlüsselung des menschlichen Genoms entscheidend vorangetrieben. Dass zwei so bekannte Forscher Grenzen übertreten, soll andere ermutigen.

Die Übergabe zeitgleich zur Eröffnung des mit rund 30.000 Teilnehmern weltweit größten Krebskongresses in Chicago, zu dem die American Society of Clinical Oncology (ASCO) eingeladen hatte, war gut kalkuliert. Denn gerade Genanalysen haben sich zu einem elementaren Werkzeug im Kampf gegen Krebs entwickelt. Der Blick ins Erbgut verrät Forschern und Ärzten immer häufiger, ob Patienten ein erhöhtes Risiko in ihrem Erbgut tragen, an Krebs zu erkranken, und welche Therapie einem Patienten hilft.

Klar ist heute, dass es nicht das eine Wundermedikament geben wird, das sich gegen nahezu alle Krebsarten einsetzen lässt. Stattdessen setzen die Wissenschaftler auf individuelle Therapien. Dafür suchen sie nach Wirkstoffen, die eine Krebszelle auf ihrer Hülle oder in ihrem Innern angreifen. Frühere und bessere Diagnosen sollen die Heilungschancen verbessern; Impfungen sollen Krebs gar verhindern. Die gezielter wirkenden Stoffe stellen bereits drei Viertel aller neuen Krebsmedikamente, rund ein Dutzend sind zugelassen. Der Löwenanteil von weltweit rund 400 Wirkstoffen, die derzeit klinisch erprobt werden, gehören zu dieser Spezies. Die Umsätze steigen jährlich um rund 20 Prozent. Bis zum Ende des Jahrzehnts werden sie sich nach Schätzung des Marktforschungsunternehmens IMS Health auf 70 Milliarden Dollar verdoppeln. Alle großen Pharmakonzerne sind an Bord. „Krebsforschung hat für uns die höchste Priorität“, sagt David Epstein, Chefonkologe von Novartis. „Wir haben sieben Substanzen gegen elf verschiedene Krebsarten in zulassungsrelevanten klinischen Studien.“

Um schnell zu Ergebnissen zu kommen, arbeiten die Forscher der Novartis Institutes for Biomedical Research (NIBR) wie andere Hersteller in internationalen Netzen mit, Novartis an sieben Standorten in den USA, Europa und Asien.

Krebs ist trotz des medizinischen Fortschritts nach Herz- und Kreislaufkrankheiten weltweit die zweithäufigste Todesursache. In Deutschland erkranken jedes Jahr mehr als 400.000 Menschen – Tendenz steigend. Die Zunahme hängt mit der höheren Lebenserwartung zusammen. Im Alter nimmt nicht nur die genetische Stabilität ab. Der Körper verliert auch an Fähigkeit, entartete Zellen, die Ursache für die Tumoren, zu reparieren. Deshalb steigt die Zahl der Erkrankungen vom 60. Lebensjahr an deutlich an. Als wichtigster Einzelrisikofaktor gilt Tabakrauch, aber auch UV-Strahlen, hormonelle Einflüsse und genetische Disposition erhöhen die Gefahr, an Krebs zu erkranken.

Der erste Schritt, den Krebs zu bekämpfen, ist immer noch, den Tumor in einer Operation zu entfernen. Danach erhalten Patienten eine Strahlen- und Chemotherapie, um gestreute Krebszellen zu vernichten, die im Körper Tochtergeschwülste bilden könnten. Das Problem dabei: Bestrahlung und Zellgifte vernichten nicht nur kranke, sondern auch gesunde Zellen. Was den Kranken heilen soll, schadet ihm zugleich – manchmal so sehr, dass eine Therapie abgebrochen werden muss, etwa wenn die Zellen im Knochenmark nicht mehr genügend Blut bilden. „Die Zellgifte wirken zu unspezifisch“, sagt Otmar Wiestler, Chef des Deutschen Krebsforschungszentrums (DKFZ) in Heidelberg.

Einen Ausweg bieten maßgeschneiderte Therapien. Sie zu entwickeln ist allerdings extrem aufwendig, wie das Beispiel Brustkrebs zeigt. In Deutschland erkranken jährlich 50.000 Frauen daran, so häufig wie an keinem anderen Krebs. Weltweit ist Brust- nach Hautkrebs die zweithäufigste Krebsart bei Frauen. Jeder Brustkrebs ist jedoch anders. Je genauer die Forscher hinschauen, desto mehr Unterschiede entdecken sie, desto feiner wird die Klassifizierung. Und es ergeben sich neue Fragen: Welcher Tumor bedarf einer Chemotherapie? Wo wirken Hormonblocker besser? Die Wissenschaftler suchen beinahe bei jedem einzelnen Tumor nach einem geeigneten Angriffspunkt.

Dafür spielen Gentests eine immer bedeutendere Rolle. Das ist ein Grund, warum sich die Koryphäen Watson und Venter so vehement für ihre Weiterentwicklung einsetzen. Um noch zuverlässiger zu wissen, ob beispielsweise ein Brustkrebstumor auf weibliche Hormone wie Östrogen und Progesteron mit verstärktem Wachstum reagiert, hat Holger Sültmann vom DKFZ einen neuen Gentest ausgetüftelt. Der weist die Andockstellen für diese Hormone anhand von zehn charakteristischen Genen in oder auf der Krebszelle sicher nach. Bisher fahnden Labors mit angefärbtem Tumorgewebe unter dem Mikroskop nach solchen Bindungsstellen. Besitzt der Tumor nur wenige davon, kann er im Labor oft nicht als hormonempfindlich identifiziert werden und bleibt möglicherweise unbehandelt. Ärzte wissen jedoch, dass Hormonblocker auch dann gegen die entarteten Zellen wirken, wenn die Krebszellen nur wenige Bindungsstellen für Hormone haben.

Werden die Hormone durch Medikamente wie Tamoxifen von AstraZeneca blockiert, wuchern die Zellen langsamer oder die krankhafte Teilung hört sogar ganz auf. „Diese Behandlung ist bei hormonempfindlichen Tumoren oft wirksamer als eine Chemotherapie“, sagt Wiestler. Gentests können zudem für Frauen sinnvoll sein, deren Mutter vor dem 50. Lebensjahr an Brustkrebs erkrankt ist. Dann ist das Risiko selbst zu erkranken deutlich erhöht. Von den 50.000 Frauen, die jährlich erkranken, leiden 2500 bis 5000 Patientinnen an der erblichen Form des Brustkrebs, wobei die Hälfte von ihnen aufgrund einer Mutation in den Genen BRCA1 oder BRCA2 erkrankt. Aber nicht alle Frauen, bei denen das Gen nachgewiesen ist, bekommen auch tatsächlich Krebs. Denn jedes Gen liegt im Zellkern doppelt vor, eines von der Mutter, eines vom Vater. Vererbt die Mutter das Brustkrebsgen und der Vater ein gesundes, bricht meist kein Krebs aus. Es müssen noch andere Faktoren hinzukommen. Ärzte raten Frauen bei denen eine Genveränderung gefunden wurde, an einem Früherkennungsprogramm teilzunehmen. Die Brust wird dabei mit Ultraschall, Kernspin und Röntgengeräten durchleuchtet. So hoffen sie, Tumoren möglichst früh zu entdecken und sie zu entfernen.

Die Forscher sind noch weiteren Schwachstellen der Tumoren auf der Spur. So tragen zwei bis drei von zehn Patientinnen ungewöhnlich viele sogenannte Her-2-Schalter auf der Oberfläche ihrer Krebszellen. Sobald dort Wachstumsfaktoren anschwemmen, treiben diese die Zellen dazu an, sich ungewöhnlich schnell zu vermehren. Genau das soll eine Art biologische Präzisionswaffe verhindern: Monoklonale Antikörper, das sind große Moleküle, besetzen die Her-2-Schalter, sodass sich die Wachstumsfaktoren nicht mehr darauf setzen können.

Vor sieben Jahren wurde der synthetische Antikörper Herceptin von Roche zugelassen, zunächst nur für Patientinnen mit Metastasen. Seit Sommer 2006 ist Herceptin auch für Frauen zugelassen, die Her-2-positiv sind, aber keine Metastasen haben. Die Rückfallgefahr sinkt dadurch deutlich. In Chicago vorgestellte Studien weisen allerdings auf das Risiko von Herzschäden hin, weil sich Her-2-Rezeptoren auch auf Herzmuskelzellen finden. Deshalb muss die Herzfunktion während der Behandlung überwacht werden.

Eine weitere Medikamentengruppe, auf die Pharmaunternehmen und Patienten gleichermaßen hoffen, sind Wirkstoffe, die den Tumor aushungern, sogenannte Angiogenesehemmer (siehe Grafik oben). Um zu wachsen und Tochtergeschwülste zu bilden, ist der Tumor ab einer gewissen Größe darauf angewiesen, neue Blutgefäße zu bilden, über die er ausreichend mit Nährstoffen versorgt wird. Um diese Neubildung von Gefäßen, die sogenannte Angiogenese, anzuregen, setzt er einen körpereigenen Botenstoff frei, den Wachstumsfaktor VEGF (vascular endothelial growth factor). Neue Wirkstoffe wie Bevacizumab von Roche blockieren ihn. Die Folge: Der Tumor hungert aus.

Das Marktpotenzial für diese Angiogenese-Hemmer schätzt die Schweizer Bank Vontobel auf 13 Milliarden Dollar. Das bisher meistverkaufte Präparat aus dieser Klasse ist Avastin, ebenfalls vom Schweizer Pharmahersteller Roche und dessen Tochter Genentech aus San Francisco. Jüngste, in Chicago vorgestellte Studien belegen, dass Avastin bei Brust-, Lungen- und Nierenkrebs positive Effekte zeigt. Bisher wurde das Medikament vor allem für die Behandlung von Darmkrebs eingesetzt.

Bis heute versprechen die wenigsten Wirkstoffe eine Heilung, aber sie verlängern das Leben. So präsentierte Bayer eine Untersuchung, nach der Patienten mit einem Leberzellkarzinom im Durchschnitt drei Monate gewinnen, wenn sie mit dem Medikament Nexavar behandelt werden. Bayer setzt das Mittel auch gegen Nierenkrebs ein. „Da es bis jetzt keine Therapie gibt, die die Überlebenszeit der vielen Tausend Patienten mit Leberkrebs deutlich verlängert, können die Ergebnisse Nexavar zur Standardtherapie für Leberkrebs werden lassen“, hofft Josep Llovet, Leiter der Studie. Bayer will die Zulassung in den USA und Europa noch in diesem Jahr beantragen.

Verbissen kämpfen die Wissenschaftler um jeden Monat. Der große Durchbruch zeichnet sich jedoch auch nach Jahrzehnten der Forschung und Milliardenausgaben nicht ab. „Wir verzeichnen Erfolge in kleinen Schritten“, sagt Leonard Lichtenfeld von der American Cancer Society. Besonders nachhaltig sind sie bei der Behandlung von Brustkrebs: In der Achtzigerjahren starben 27 Prozent der Patientinnen im Verlauf von fünf Jahren, zehn Jahre später waren es noch 20 Prozent. Hodenkarzinome sind heute fast zu 100 Prozent heilbar. Kaum verbessert haben sich dagegen die Chancen bei Lungenkrebs, dem häufigsten Krebs bei Männern in Deutschland.

60 Prozent der Menschen, bei denen Anfang dieses Jahrzehnts in Deutschland Krebs diagnostiziert wurde, lebten fünf Jahre später noch. Das besagt eine Statistik des Krebsforschungszentrum in Heidelberg. Nach Berechnung des DKFZ-Epidemiologen Hermann Brenner werden unter denen, die heute an Krebs erkranken, 64 Prozent in fünf Jahren noch leben. Brenner macht Mut: „Der Kampf gegen den Krebs trägt Früchte.“

Beispiel Gebärmutterhalskrebs: Lange galt er als nahezu unheilbar, weil er anfangs meist schmerzlos verläuft und deshalb oft zu spät entdeckt wird. Jetzt steht erstmals ein Impfstoff zur Verfügung, der die Entstehung verhindern soll. Der Krebs wird von humanen Papillomviren (HPV) ausgelöst, die beim Geschlechtsverkehr übertragen werden. Das hatte der ehemalige Leiter des DKFZ, Harald zur Hausen, 1983 entdeckt. Es gibt rund 100 verschiedene Arten von HPV, doch bei sieben von zehn Frauen mit Gebärmutterhalskrebs finden sich zwei HPV-Typen: HPV 16 und HPV 18.

Seit Oktober 2006 ist in Deutschland der Impfstoff Gardasil von Sanofi Pasteur MSD zugelassen, der an Mädchen und Frauen im Alter von 10 bis 26 Jahren getestet wurde. In Chicago stellte GlaxoSmithKline eine Studie zum Impfstoffkandidaten Cervarix vor, wonach auch Frauen über 26 Jahre geschützt werden. Noch nach mehr als fünf Jahren lag der Schutz bei fast 100 Prozent. Cervarix soll noch dieses Jahr die Zulassung erhalten.

Gute Nachrichten gibt es auch von der Behandlung einer speziellen Form des Blutkrebses, der chronischen myeloischen Leukämie. Noch vor wenigen Jahren glich diese Diagnose einem Todesurteil. Dann brachte Novartis 2001 mit Glivec ein Medikament auf den Markt, das 90 Prozent der Patienten heilt. Die Schweizer setzten damit im vergangenen Jahr rund zwei Milliarden Euro um. „Das war der Beginn einer Revolution“, sagt der Marburger Onkologe Andreas Neubauer. Der Wirkstoff von Glivec, Imatinib, ist ein ganz kleines chemisches Molekül, im Fachjargon „Small Molecule“ genannt. Es hemmt ein Eiweiß, die Proteinkinase, deren Bauplan wie bei allen Proteinen durch Gene festgelegt ist. Normalerweise sind diese Eiweiße für die Signalweiterleitung in der Zelle zuständig. Wird diese Funktion durch ein defektes Gen gestört, fördern sie stattdessen das Wuchern der Zellen und verhindern, dass kranke Zellen absterben.

Roman Thomas, Wissenschaftler am Kölner Max-Planck-Institut für neurologische Forschung, sagt weitere große Fortschritte voraus: „In zehn Jahren werden die Therapien für einige Krebsarten so weit sein, dass die Patienten nicht mehr sterben, allerdings ihr Leben lang Medikamente nehmen müssen.“
