Topotargets meets primary endpoint!

BELIEF is a pivotal, open-label, multi-center, single-arm efficacy and safety trial of i.v. belinostat in patients with relapsed or refractory PTCL. FDA has granted belinostat Orphan Drug and Fast Track designation for the treatment of PTCL. The trial was initiated in December 2008 and recruitment was completed with 129 patients in September 2011. In total, the study included approximately 100 clinical centers globally.

PTCL is a hematological disease including a heterogeneous group of malignancies of T-cell origin that represents approximately 10-15% of all cases of non-Hodgkin’s lymphoma. PTCL is an aggressive, high-grade type of cancer with a poor prognosis of expected average survival of approximately two years from diagnosis without treatment. The projections for annual cancer incidences point to 15,500 new cases of PTCL in the US, Japan, and five largest EU countries.

Belinostat is a novel pan-HDAC inhibitor in late-stage clinical development with more than 1,000 patients treated. Belinostat has a promising safety profile, which allows combination with traditional chemotherapy. Preclinical experiments demonstrated belinostat to be effective against multiple cancers by inhibiting cell proliferation and inducing programed cell death (apoptosis) in tumor cells. Belinostat has been tested in a number of phase I/II clinical trials in hematological cancers and solid tumors both in mono- and combination therapy. Data from these trials have provided evidence of the anti-tumor effect of belinostat, including as monotherapy in PTCL and cutaneous T-cell lymphoma (CTCL), liver cancer, and thymoma.

Announcement no. 18-12 Belinostat gets EU Orphan Drug Designation for treatm

Hintergrund: Die Prognose für Patienten mit R / R PTCL bleibt arm. Romidepsin und Pralatrexat sind in den USA zugelassen, mit insgesamt Ansprechraten (ORR) von 25% bzw. 27% 1, 2 . Pralatrexat, ein Anti Folsäure, verursacht Myelosuppression und Mukositis. Müdigkeit war prominent mit Romidepsin ein HDACi. Diese Klasse wurde in QTc-Verlängerung in Verbindung gebracht. Belinostat, ein Roman pan-HDAC, in der Voruntersuchung hat ähnliche ORR in R / R PTCL und ist gut mit gemeinsamen Grad 1-2 Toxizitäten, Magen-Darm-und verfassungsrechtlichen toleriert 3 . Diese Befunde waren nicht gedämpft in Kombination Studien 4 . Glaube ist die entscheidende Ph-2-Studie, die die Sicherheit und Wirksamkeit von Belinostat in R / R PTCL ausgewertet. Wir präsentieren die vorläufigen Daten zur Sicherheit aus dem Glauben Studie.

Methoden: Der Glaube ist eine offene, multizentrische, einarmige Wirksamkeit und Sicherheit Studie bei Patienten mit R / R PTCL nach Versagen von mindestens einer systemischen Therapie. PTCL Diagnose wurde durch die zentrale Pathologie Berichtsjahr bestätigt. EKGs wurden zentral überprüft. Wichtige Einschlusskriterien waren: Thrombozytenzahl ≥ 50.000 / ul, keine vorherige HDACi Therapie, messbarer Erkrankung und angemessene Organfunktion. Belinostat wurde als 30 min IV-Infusion bei 1000 gegebenen mg / m 2 an den Tagen 1-5 der 3-wöchigen Zyklus bis Fortschreiten der Krankheit oder unannehmbare Toxizität. Der primäre Endpunkt war ORR. Die Sicherheit wurde durch 30 Tage der letzten Dosis von Belinostat überwacht. Wirksamkeit Bestimmungen sind im Gange.

Ergebnisse: Insgesamt 129 Patienten, 53% Männer, Durchschnittsalter 63 Jahre (Bereich 29-81 Jahre) behandelt wurden. Die mittlere Zahl der Zyklen war 2 (Bereich 1-31). Eine Dosisreduktion trat bei 11% der Patienten und 1% hatten zwei Dosisreduktion. AEs führte Dosis Verzögerungen bei 21% der Patienten und 18% für AES eingestellt, einschließlich Tod. Grad 3/4 nicht hämatologische Nebenwirkungen beobachtet in> 3% der Patienten enthalten Asthenie / Müdigkeit 9%, Lungenentzündung 7%, Dyspnoe 6%, Infektion 4%, fiebrige Neutropenie 4%, Pruritus 3%, tiefe Venenthrombose 3% und Hypotonie 3%. Grade 3 QTc-Verlängerung wurde in 2% der Patienten berichtet. Grad 3/4 hämatologischen Toxizitäten waren: Thrombozytopenie 6% bei Patienten mit einer Thrombozytenzahl von ≥ 100.000, Anämie, Leukopenie und Neutropenie jeweils 13%. Insgesamt 23 Patienten (18%) starben bei der Behandlung oder innerhalb von 30 Tagen nach der letzten Dosis, vorwiegend aufgrund von PTCL Progression. Kein Tod wurde Belinostat zugeschrieben.

Schlussfolgerungen: Belinostat ist gut mit einem günstigen Sicherheitsprofil bei Patienten mit R / R PTCL toleriert. Basierend auf Wirksamkeit in der früheren Ph-2-Studie und die Sicherheit in dem Glauben Studie ist Belinostat eine mutmaßliche gut verträgliche Option für die Behandlung von PTCL. Andere Studien zeigen, dass die volle Dosen Belinostat mit anderen zytotoxischen Therapien machen Kombinationstherapie für Patienten mit PTCL machbar kombiniert werden können.

Announcement Nr. 01-13 Belinostat hat günstige Sicherheitsprofil bei PTCL BELIEF study.pdf

On January 24, 2013, Topotarget announced that preliminary safety data from the BELIEF trial in PTCL, presented at the T-Cell Lymphoma Forum 2013 in San Francisco, USA, showed that belinostat has a favorable safety profile and that the compound has the potential to become a well-tolerated alternative for the treatment of PTCL. The favorable safety outcome from this trial, as well as experience from earlier belinostat trials, shows that full doses of belinostat can be combined with other cytotoxic regimens making combination therapy for cancer patients feasible. The low incidence of myelosuppression is of special notice as this offers the opportunity to combine belinostat with other cytostatic agents for the treatment of patients with PTCL.

New Drug Application
Belinostat is currently being developed jointly by Topotarget and Spectrum Pharmaceuticals. Spectrum possesses the commercial rights to market belinostat in North America and India. A New Drug Application (NDA) for belinostat in PTCL is expected to be filed with the FDA by Spectrum in mid-2013.

Introduction: PTCL is a heterogeneous, aggressive disease with poor prognosis. AITL is a subtype representing 15–20% of PTCL. AITL treatment is similar to other forms of PTCL with 5-year OS rates of 10–32%.

Methods: BELIEF was a single-arm study of belinostat in patients with R/R PTCL after failure of ≥1 prior systemic therapies. Entry criteria were measurable disease, platelets≥50,000/ml, no prior histone deacetylase inhibitor (HDACi) therapy, and adequate organ function. PTCL was confirmed by central pathology review group (CPRG). Belinostat (1000mg/m, 2 IV_5 days) was given as a 3week cycle until progression or unacceptable toxicity. Tumor response was assessed by Cheson 2007 criteria. The primary endpoint was ORR. Subgroup analysis examined response by PTCL subtype.

Results: Of 129 patients enrolled with R/R PTCL, data presented here are from22 patients with CRPG confirmed AITL, including 5 with baseline platelets <100,000/ml, a median age of 70 (range 48–78) years, 64% female, a median of 2 (range 1–5) prior therapies (21 CHOP/CHOP-like; 4 stem cell transplant), and 8 had bone marrow involvement. Belinostat was administered for a median of 4 cycles (1–29) with a median dose intensity of 94%. Dose reductions in 3 patients were due to grade 2 and 3 QTC prolongation in 1 patient, immune hemolytic anaemia, and hypokalemia/dyspnea/fever. Response rate for AITL was 45% (4 CR, 6 PR) with a median duration of response of 7.5 (1.6–29.4) months. Of the responders, 2 had baseline platelets of 78,000 and 79,000; with one patient achieving CR. Data is reported as of 31AUG2012, with 3 patients remaining on treatment at 55, 105, and 135 weeks* and 19 discontinued. Discontinuations were due to PD in 14 patients, AEs in 2 and other reasons for 3. Sixteen patients have died, 5 were alive, and 1was lost to follow-up. Median PFS and OS for patients with AITL were 5.8 and 9.2 mos, respectively.

Conclusions: Belinostat treatment resulted in a 45% response rate among patients with R/R AITL. The favorable safety profile observed warrants further investigation of belinostat-based regimens to optimize outcomes for AITL.
