DOR BioPharma, Inc. (OTCBB:DORB) ("DOR" or the "Company"), announced today that it has successfully completed its cGMP (current Good Manufacturing Practices) milestone for the production of RiVax(TM), DOR's vaccine against ricin toxin. The milestone was achieved in the performance of a Challenge Grant totaling $6.4 million previously awarded to DOR in September 2004 by the National Institute of Allergy and Infectious Diseases (NIAID), a unit of the National Institutes of Health. The safety and immunogenicity of RiVax(TM) has recently been evaluated in a Phase I clinical trial in healthy volunteers, and the results were published earlier this year in the Proceedings of the National Academy of Sciences. DOR and its manufacturing partner, Cambrex BioSciences Baltimore, Inc., have developed a robust and reproducible manufacturing process for the large-scale production of RiVax(TM). The completion of cGMP manufacture of RiVax(TM) forms one of the crucial milestones in the performance of the work conducted under the NIH grant. Based on the release and further toxicology testing of the cGMP batches, the Company is planning to test the vaccine in further clinical trials. These trials will examine the influence of an immunological adjuvant formulation and vaccination regimen on the human immune response. These studies will be directed towards providing safety and immunogenicity data needed for licensure of the vaccine by the FDA. Further animal testing is also planned to provide correlation of antibody levels in human serum with protection against ricin exposure in animal models. Because vaccine efficacy for exposure of humans to ricin toxin can only be tested in animals, the FDA has established a two animal rule. Under this rule, the FDA can permit human licensure of a vaccine by relying on results from animal trials when human trials cannot ethically evaluate efficacy. "We are pleased that we have achieved this critical milestone and are encouraged that we will have a means to manufacture RiVax(TM) at the scale necessary for potential future immunization programs of civilian or military personnel," stated Michael T. Sember, President and CEO of DOR BioPharma. "We are well on the pathway to successful development of RiVax(TM) as we continue work on this important biodefense countermeasure. We will continue to work closely with our partners and NIAID to propel the vaccine through the next phase of clinical studies." Ricin toxin is a potential bioterror threat due to its highly lethal toxicity in small doses, ease of manufacture, and ability to be aerosolized. Exposure to small amounts, especially by inhalation, can lead to lung damage, nausea, fever, abdominal pain, and death within several days. The need for protective countermeasures against ricin has been emphasized by its recent and continued use as a biological weapon. Currently there are no FDA approved vaccines or therapeutics against ricin toxin.
About DOR BioPharma, Inc.
DOR BioPharma, Inc. is a biopharmaceutical company addressing life-threatening side effects of cancer and cancer treatments, serious gastrointestinal diseases and disorders, and biomedical countermeasures. Our lead product, orBec(R) (oral beclomethasone dipropionate), is a potent, locally-acting corticosteroid being developed for the treatment of gastrointestinal Graft-versus-Host disease (GI GVHD), a common serious complication of bone marrow transplantation for cancer, as well as other GI disorders characterized by severe inflammation. We plan to file a new drug application (NDA) with the FDA for orBec(R) for the treatment of GI GVHD in the July - August timeframe of 2006. Through our BioDefense Division, we are developing biomedical countermeasures pursuant to the paradigm established by the recently enacted Project BioShield Act of 2004. Our biodefense products in development are bioengineered vaccines designed to protect against the deadly effects of ricin toxin and botulinum toxin, both of which are considered serious bioterrorism threats. Our ricin toxin vaccine, RiVax(TM), has successfully completed a Phase I clinical trial in normal volunteers. We have also initiated a botulinum toxin therapeutic development program based on rational drug design.
