All three of the clinical studies described in the abstracts are scheduled for presentation at the upcoming ASH Annual Meeting, which will be held on December 10-13, 2005, in Atlanta, Georgia:
"Forodesine (Fodosine(TM)), a PNP Inhibitor Active in Relapsed or Refractory T-Cell Leukemia Patients (Phase II Study) (R. Furman et al.) will be presented by Dr. Richard R. Furman of Cornell University, during the Poster Session on Saturday, December 10 at 6:00 p.m. The poster includes an analysis of the Phase II trial data demonstrating that intravenous Fodosine(TM) is active with minimal toxicity, as a single agent in relapsed or refractory T-cell leukemia.
"Development of Forodesine Hydrochloride (FH), an Inhibitor of Purine Nucleoside Phosphorylase, for Patients with Chronic Lymphocytic Leukemia (CLL)" (K. Balakrishnan et al.), will be presented by Dr. Kumudha Balakrishnan of The University of Texas M.D. Anderson Cancer Center, during the Poster Session on Sunday, December 11 at 6:00 p.m. Dr. Balakrishnan will discuss results from a Phase II clinical study of Fodosine(TM), the first trial of a PNP inhibitor for the treatment of CLL.
"Phase I/II Study of Oral Fodosine(TM), a PNP Inhibitor in Refractory Cutaneous T-Cell Lymphoma Patients" (M. Duvic et al.) will be presented by Dr. Madeleine Duvic of The University of Texas M.D. Anderson Cancer Center, during the Poster Session on Sunday, December 11 at 6:00 p.m. Dr. Duvic will present data from the Phase I/II trial in which Fodosine(TM) showed preliminary evidence of clinical activity in refractory CTCL patients.
About BioCryst
BioCryst Pharmaceuticals, Inc. designs, optimizes and develops novel drugs that block key enzymes involved in cancer, cardiovascular diseases, autoimmune diseases, and viral infections. BioCryst integrates the necessary disciplines of biology, crystallography, medicinal chemistry and computer modeling to effectively use structure-based drug design to discover and develop small molecule pharmaceuticals.
BioCryst's lead product candidate, Fodosine(TM), is a transition-state analog inhibitor of the target enzyme purine nucleoside phosphorylase (PNP). The drug is currently in a Phase IIa trial for patients with T-cell leukemia and a combination IV and oral Phase I pharmacokinetic trial in healthy volunteers. Results of the Phase IIa and the Phase I pharmacokinetic trial will assist in the design of a planned combination IV and oral Phase IIb pivotal clinical trial in patients with T-cell leukemia. The Company has requested a Special Protocol Assessment from the FDA for this planned trial. Additionally, Fodosine(TM) is currently being studied in a Phase I trial with an oral formulation in cutaneous T-cell lymphoma (CTCL) and a Phase II trial in chronic lymphocytic leukemia (CLL). BioCryst also plans to initiate a Phase I/II trial in B-cell acute lymphoblastic leukemia during 2005. Fodosine(TM) has been granted Orphan Drug status by the U.S. Food and Drug Administration for three indications: T-cell non-Hodgkin's lymphoma, including CTCL; CLL and related leukemias including T-cell prolymphocytic leukemia, adult T-cell leukemia, and hairy cell leukemia; and for treatment of B-cell acute lymphoblastic leukemia (ALL).
Additionally the FDA has granted "fast track" status to the development of Fodosine(TM) for the treatment of relapsed or refractory T-cell leukemia. A Phase Ib study with BioCryst's second-generation PNP inhibitor, BCX-4208, was recently initiated and is being conducted with the goal of initiating Phase II studies in patients with psoriasis in 2006. BioCryst has re-initiated clinical development of peramivir, an inhibitor of influenza neuraminidase, with a focus on intravenous and intramuscular delivery. Also, BioCryst has identified a clinical candidate, BCX-4678, in its hepatitis C polymerase inhibitor program, and is advancing this compound through preclinical testing with the goal of filing an IND in early 2006.
