BARDA Soligenix (SNGX.OB) to Submit Contract Proposal for Development of OrbeShield™ in GI ARS


1/7/2013 10:06:43 AM

PRINCETON, N.J., Jan. 7, 2013 /PRNewswire/ -- Soligenix, Inc. (OTCQB: SNGX) (Soligenix or the Company), a development stage biopharmaceutical company, announced today that pursuant to review of the Company's white paper on development of OrbeShield as a countermeasure for the gastrointestinal effects of acute radiation syndrome (GI ARS), the Biomedical Advanced Research and Development Authority (BARDA), Division of Chemical, Biological, Radiological and Nuclear (CBRN) Medical Countermeasures has informed the Company that after careful analysis and consideration, it is inviting Soligenix to submit a full proposal for a potential multi-year, multi-million dollar contract to develop OrbeShield from its current level of technical readiness to FDA approval.

Soligenix submitted its white paper entitled "OrbeShield, oral beclomethasone 17,21-dipropionate (BDP), a candidate broad spectrum therapeutic countermeasure for GI ARS," to BARDA in response to a Broad Agency Announcement (BARDA-BAA-12-100-SOL-00011) for advanced research and development of medical countermeasures for chemical, biological, radiological and nuclear threats. BARDA is interested in the advanced development and eventual licensure/approval of effective medical countermeasures that mitigate, treat, affect, delay, or interrupt the progression of injuries resulting from an acute exposure to radiation from a radiological/nuclear accident or attack, particularly injuries associated with ARS.

In a canine model of GI ARS, OrbeShield demonstrated a statistically significant survival advantage in animals that received OrbeShield therapy up to 24 hours following exposure to lethal doses of total body irradiation (TBI) when compared with placebo control animals (p=0.04). Median survival post TBI exposure in the control group was 8 days, compared to 87 days in the OrbeShield treated group. A subsequent study to replicate and expand upon the observations made in the canine model is being initiated and, like the previous study, is supported by a recent National Institute of Allergy and Infectious Diseases (NIAID) Small Business Innovation Research (SBIR) grant award.

"We are very excited by BARDA's invitation to submit a full proposal for development of OrbeShield as a medical countermeasure against GI ARS," stated Christopher J Schaber, PhD, President & Chief Executive Officer of Soligenix. "Although there are no guarantees, we believe that we are well-positioned to receive BARDA support for this indication and that the full proposal will allow us to further demonstrate the growing body of compelling scientific evidence supporting OrbeShield's potential as a countermeasure for GI ARS. We intend to submit our proposal to BARDA in February 2013 and look forward to their response. Meanwhile, we continue to develop OrbeShield pursuant to our recent $600,000 SBIR grant supporting further GI ARS canine studies."

The invitation to submit a proposal is non-binding and the selection of Soligenix's white paper for submission of a full proposal is not a guarantee of a BARDA contract. A contract award will require a favorable technical and scientific review by BARDA followed by negotiation of fair and reasonable contract terms.

About GI ARS

ARS occurs after toxic radiation exposure and involves several organ systems, notably the bone marrow the GI tract and later the lungs. In the event of a nuclear disaster or terrorist detonation of a nuclear bomb, casualties exposed to >2 Gy are at high risk for development of clinically significant ARS. Exposure to high doses of radiation exceeding 10-12 Gy causes acute GI injury which can result in death in 5-15 days. The GI tract is highly sensitive due to the requirement for incessant proliferation of crypt stem cells and production of mucosal epithelium. The extent of injury to the bone marrow and the GI tract are the principal determinants of survival after exposure to TBI. Although the hematopoietic syndrome can be rescued by bone marrow transplantation or growth factor administration, there is no established treatment or preventive measure for the GI damage that occurs after high-dose radiation. Therefore, there is an urgent need to develop specific medical countermeasures against the lethal pathophysiological manifestations of radiation-induced GI injury.

About OrbeShield

OrbeShield is formulated for oral administration in GI ARS patients as a single product consisting of two tablets; one tablet releases BDP in the proximal portions of the GI tract and the other tablet releases BDP in the distal portions of the GI tract. BDP has been marketed in the United States and worldwide since the early 1970s as the active pharmaceutical ingredient in inhalation products for the treatment of patients with allergic rhinitis and asthma. Oral BDP may also have application in treating other GI disorders characterized by severe inflammation such as Crohn's disease and radiation enteritis.

About Soligenix, Inc.

Soligenix is a development stage biopharmaceutical company developing products to treat serious gastrointestinal diseases where there remains an unmet medical need, as well as developing several biodefense vaccines and therapeutics. Soligenix is developing proprietary formulations of oral BDP (beclomethasone 17.21-dipropionate) for the prevention/treatment of gastrointestinal disorders characterized by severe inflammation, including pediatric Crohn's disease (SGX203), acute radiation enteritis (SGX201) and chronic Graft-versus-Host disease (orBec®), as well as SGX942 for the treatment of oral mucositis.

Through its BioDefense Division, Soligenix is developing countermeasures pursuant to the Biomedical Advanced Research and Development Authority (BARDA) Strategic Plan of 2011-2016 for inclusion in the US government's Strategic National Stockpile. Soligenix's lead biodefense products in development are a recombinant subunit vaccine called RiVax, which is designed to protect against the lethal effects of exposure to ricin toxin and VeloThrax, a vaccine against anthrax exposure. RiVax has been shown to be well tolerated and immunogenic in two Phase 1 clinical trials in healthy volunteers. Both RiVax and VeloThrax are currently the subject of a $9.4 million National Institute of Allergy and Infectious Diseases (NIAID) grant supporting development of Soligenix's new vaccine heat stabilization technology known as ThermoVax. Soligenix is also developing OrbeShield for the treatment of gastrointestinal acute radiation syndrome (GI ARS) under a $600,000 NIAID Small Business Innovation Research (SBIR) grant. OrbeShield has previously demonstrated statistically significant preclinical survival results in two separate canine GI ARS studies funded by the NIH.
