Antineoplaston treatment for gliomas granted orphan drug designation by FDA

The Burzynski Research Institute, Inc. (BRI) has announced that its antineoplaston A10 and antineoplaston AS2-1 therapy (ANP) has been granted orphan drug designation by the U.S. Food and Drug Administration ("FDA") for the treatment of gliomas. It is estimated that in 2008 more than 21,000 men and women in the U.S. will be diagnosed with this type of cancer, with prevalence estimated at approximately 84,000 cases.

"We are encouraged by the FDA's action. Initially, BRI sought orphan drug designation for ANP in optic pathway glioma in children, a much narrower indication involving a smaller segment of tumors," said Dr. Stanislaw R. Burzynski, M.D., Ph.D. "However, the FDA extended orphan drug designation to all gliomas, a recognition we believe underlies the broad potential of anitneoplaston therapy for the treatment of patients with cancer of the brain and nervous system. There is now even more motivation for us to evaluate our therapy as an innovative and efficacious choice in a treatment spectrum where disease management options are still quite limited."

Orphan drug designation, as granted by the FDA's Office of Orphan Products Development, was designed to encourage clinical development of products for use in rare diseases or conditions, usually defined as affecting fewer than 200,000 people in the United States. Orphan drug designation provides an economic incentive that stimulates the development of new products in the oncology field and allows for seven years of market exclusivity upon final FDA approval, as well as clinical study and R&D support, reduction in regulatory fees and potential tax credits.

Research and development efforts are focused on basic ANP research and 19 Phase II clinical trials, some of which are coming now to a successful conclusion. Since ANP effects approximately 100 genes instrumental in the growth of glioblastoma multiforme, the results of research have been and will be presented in a number of neuro-oncology meetings and published as abstracts in Neuro-Oncology. Earlier this year the BRI team presented at the 13th International Symposium of Pediatric Neuro-Oncology in Chicago, Illinois (June 29-July 2, 2008), a successful preliminary report on the phase II study of ANP in children with optic pathway glioma. At the September 2008 annual meeting of the European Association for Neuro-Oncology in Barcelona, Spain, BRI presented two reports. In one of them, it was described how the ingredients of ANP down-regulate energy producing pathways in glioblastoma cells. The second report described preliminary successful results of Phase II study of ANP in patients with recurrent anaplastic astrocytoma. Most recently, BRI presented two additional reports on preliminary results of phase II study of ANP in patients with newly-diagnosed anaplastic astrocytoma and on the affects of ANP's ingredients on cell cycle checkpoint which lead to apoptosis in human glioblastoma cells at the Society of Neuro-Oncology's annual meeting in November 2008.

Burzynski Research Institute, Inc. is a biopharmaceutical company committed to developing treatment for cancer based on genomic and epigenomic principles.
