This Phase 3 clinical trial, also referred to as the SUPPORTS protocol (Sparing Unnecessary Prednisone Phase 3 orBec(®) Randomized Treatment Study), will enroll an estimated 166 patients to confirm the clinically meaningful endpoints observed in previous Phase 2 and Phase 3 clinical studies. The primary endpoint is the treatment failure rate at Study Day 80. This endpoint was successfully measured as a secondary endpoint (p-value 0.005) in the Company's previous Phase 3 study as a key measure of durability following a 50-day course of treatment with orBec(®) (i.e., 30 days following cessation of treatment). The SUPPORTS trial will be conducted at major transplant centers throughout the US and is expected to complete with clinical data available in the first half of 2011.

The SUPPORTS trial will be conducted pursuant to a Special Protocol Assessment (SPA) agreement that the Company had reached with the US Food and Drug Administration (FDA). An agreement via the SPA procedure is an agreement with the FDA that a Phase 3 clinical trial's design (e.g., endpoints, sample size, control group and statistical analyses) is acceptable to support a regulatory submission seeking new drug approval. The European Medicines Agency (EMEA) also agreed that should the new confirmatory Phase 3 study produce positive results, the data would be sufficient to support a marketing authorization approval in all 27 European Union (EU) member states.

Keith Sullivan, MD, James B. Wyngaarden Professor of Medicine and Chief of the Division of Medical Oncology and Transplantation at Duke University Medical Center and Co-Principal Investigator of the SUPPORTS study, said, "In over 30 years of clinical studies evaluating potential treatments for acute GI GVHD, only the Phase 2 and 3 studies with orBec(®) have been shown to have a positive impact on both controlling GI GVHD and improving patient survival. By using these data in the design of this Phase 3 clinical study, I am confident that it has the potential to replicate the outcomes previously demonstrated including the primary endpoint. I look forward to working with the Soligenix team and my fellow clinicians in the execution of this clinical study so that transplant teams around the world can include orBec(®) as part of their arsenal to fight this debilitating disease."

"orBec(® )has demonstrated consistent and meaningful clinical benefit to patients in Phase 2 and 3 clinical trials in GI GVHD," stated Brian L. Hamilton, MD, PhD, Senior Vice President and Chief Medical Officer of Soligenix. "The depth and strength of our available Phase 3 data allowed us to design and power this confirmatory trial to maximize orBec(®)'s likelihood of success. The primary endpoint, established via the SPA procedure as the treatment failure rate at Study Day 80, is designed to replicate the statistical significance from our prior Phase 3 clinical trial with orBec(®). We look forward to completing this clinical trial and being the first company to address the unmet medical need of GI GVHD. Launching this important trial is a testimony to the extraordinary talents and efforts of the clinical and regulatory teams at Soligenix, along with the support of our partners, vendors and clinical investigators."

About GI GVHD

GI GVHD is a debilitating, painful disease and an unmet medical need. It is a common disorder among immunocompromised cancer patients after receiving hematopoietic cell transplantation. Unlike organ transplants where the patient's body may reject the organ, in GVHD it is the donor cells that begin to attack the patient's (host's) body - most frequently the gastrointestinal tract, liver and skin. Patients with mild-to-moderate GI GVHD typically develop symptoms of anorexia, nausea, vomiting and diarrhea. If left untreated, GI GVHD can progress to ulcerations in the lining of the GI tract, and in its most severe form, can be fatal. There are no FDA approved therapies to treat GI GVHD.

About orBec(®)

orBec(®) represents a first-of-its-kind oral, locally acting therapy tailored to treat the gastrointestinal manifestation of GVHD, the organ system where GVHD is most frequently encountered and highly problematic. orBec(®) is intended to reduce the need for systemic immunosuppressive drugs to treat GI GVHD. Beclomethasone dipropionate (BDP) is a highly potent, topically active corticosteroid that has a local effect on inflamed tissue. BDP has been marketed in the US and worldwide since the early 1970s as the active pharmaceutical ingredient in a nasal spray and in a metered-dose inhaler for the treatment of patients with allergic rhinitis and asthma. orBec(®) is formulated for oral administration in GI GVHD patients as a single product consisting of two tablets; one tablet is intended to release BDP in the proximal portions of the GI tract, and the other tablet is intended to release BDP in the distal portions of the GI tract.

Soligenix has previously run two randomized, double-blind, placebo-controlled clinical trials in acute GI GVHD with orBec(®). The first trial was a 60-patient Phase 2 single-center clinical trial conducted at the Fred Hutchinson Cancer Research Center. The second trial was a 129-patient pivotal Phase 3 multi-center clinical trial conducted at 16 leading bone marrow/stem cell transplant centers in the United States and France. Although orBec(®) did not achieve statistical significance in the primary endpoint of its pivotal trial, namely median time-to-treatment failure through Day 50 (p-value 0.1177), orBec(®) did achieve statistical significance in other key secondary endpoints such as the proportion of patients free of GVHD at Day 50 (p-value 0.05) and Day 80 (p-value 0.005) and the median time to treatment failure through Day 80 (p-value 0.0226), as well as a 66% reduction in mortality among patients randomized to orBec(®) at 200 days post-transplant with only 5 patient (8%) deaths in the orBec(®) group compared to 16 patient (24%) deaths in the placebo group (p-value 0.0139). At one year post randomization in the Phase 3 trial, 18 patients (29%) in the orBec(®) group and 28 patients (42%) in the placebo group died within one year of randomization (46% reduction in mortality, p-value 0.04).

Based on the Phase 2 and 3 clinical data, Soligenix filed a New Drug Application (NDA) and received an action letter requiring additional clinical data. Upon successful completion of the SUPPORTS trial, Soligenix will file a complete response to the action letter. This response to the NDA is expected to be designated a class II response with a corresponding FDA review time frame of six months.

In addition to issued patents and pending worldwide patent applications held by or exclusively licensed to Soligenix, orBec(®) also benefits from orphan drug designations in the US and in Europe for the treatment of GI GVHD, which provide for seven and 10 years of post-approval market exclusivity, respectively. Soligenix is also continuing to actively build intellectual property around oral BDP in other inflammatory conditions.

Highlights and Recent Developments:

• The initiation of enrollment in its confirmatory Phase 3 randomized, double-blind, placebo-controlled, multicenter clinical trial evaluating orBec® for the treatment of acute gastrointestinal Graft-versus-Host disease (GI GVHD). The initiation of this trial also triggered a $1 million milestone payment from Soligenix's partner Sigma-Tau Pharmaceuticals, Inc. (Sigma-Tau).
• The appointment of Robert J. Rubin, MD, to its Board of Directors.
• The completion of a corporate name change to Soligenix, Inc. from DOR BioPharma, Inc.
• The completion of a $4.4 million financing with institutional investors including its partner Sigma-Tau.
• The award of a $9.4 million grant from the National Institute of Allergy and Infectious Diseases (NIAID), a division of the National Institutes of Health (NIH). This grant will fund, over a five-year period, the development of formulation and manufacturing processes for vaccines, including RiVax(TM), that are stable at elevated temperatures.
• The award of a $500,000 NIH Small Business Innovation Research (SBIR) grant to support the conduct of a Phase 1/2 clinical trial evaluating SGX201, a time-release formulation of oral beclomethasone dipropionate (oral BDP), for the prevention of acute radiation enteritis.
• The granting of Orphan Drug Designation by the FDA's Office of Orphan Products Development for oral BDP (beclomethasone 17,21-dipropionate, or orBec®) for the treatment of gastrointestinal symptoms associated with chronic GVHD.

"By any measure, the third quarter of 2009 was a pivotal one for Soligenix," stated Christopher J. Schaber, PhD, President and CEO of Soligenix. "With the initiation of our confirmatory Phase 3 clinical trial of orBec® in acute GI GVHD, orBec® is poised to potentially be the first FDA approved therapy for this unmet medical need. Additionally, Soligenix received significant new grant funding for its biodefense and radiation enteritis programs, as well as new equity financing and a $1 million milestone payment from our North American partner Sigma-Tau. We are looking forward to completing a productive 2009 and continuing that positive momentum in 2010."

Soligenix's revenues, which primarily relate to receipts from NIH grants, for the third quarter of 2009 were approximately $767,000 compared to $606,000 for the third quarter of 2008. Revenues for the first nine months of 2009 were approximately $1.6 million compared to $1.8 million for the first nine months of 2008.

Soligenix's net loss for the third quarter of 2009 was approximately $1.7 million, or $0.01 per share, compared to $0.5 million, or $0.005 per share, for the third quarter of 2008. The net loss for the first nine months of 2009 was approximately $5.6 million, or $0.03 per share, compared to $3.1 million, or $0.03 per share, for the first nine months of 2008. These larger net losses were primarily attributed to increased research and development (R&D) spending in connection with the preparation and initiation of the confirmatory Phase 3 clinical trial of orBec® for the treatment of GI GVHD.

R&D expenses for the third quarter of 2009 were approximately $1.1 million, compared to $60,000 for the third quarter of 2008. R&D expenses for the first nine months of 2009 were approximately $3.8 million, compared to $1.4 million for the first nine months of 2008.
