FOR IMMEDIATE RELEASE

BIOCRYST AND MUNDIPHARMA INTERNATIONAL HOLDINGS LIMITED COLLABORATE ON DEVELOPMENT OF FODOSINE™

Birmingham, Alabama – February 2, 2006 – BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) and Mundipharma International Holdings Limited (Mundipharma) today announced that they have entered into an exclusive license agreement to develop and commercialize BioCryst’s lead compound, Fodosine™, in markets across Europe, Asia and Australasia* for use in oncology. 

Fodosine™ is a transition-state analog inhibitor of the target enzyme purine nucleoside phosphorylase (PNP).  The drug is currently being studied in a number of clinical trials including a Phase IIa clinical trial in patients with T-cell leukemia.  Results of this Phase IIa trial and those from a recently completed Phase I pharmacokinetic study will assist in the design of a planned Phase IIb pivotal clinical trial to test a combination of IV and oral formulations of Fodosine™ in patients with T-cell leukemia.  BioCryst has requested a Special Protocol Assessment from the U.S. Food and Drug Administration for this planned trial.

“We are delighted to have Mundipharma as our partner for the continued development of our lead product, Fodosine™,” said Charles E. Bugg, Ph.D., Chairman and CEO of BioCryst.  “We believe this collaboration will maximize the global development, commercialization, and market potential of Fodosine™ in a variety of serious medical conditions potentially including T-cell leukemia, cutaneous T-cell lymphoma, chronic lymphocytic leukemia, T-cell non-Hodgkin’s lymphoma and B-cell non-Hodgkin’s lymphoma.”

“With our proven success with DepoCyte™ (controlled-release cytarabine) for lymphomatous meningitis, Mundipharma is ideally placed to help optimize the development of Fodosine™, in order to bring the maximum benefits to those fighting to overcome these difficult to treat conditions,” said Åke Wikström, Regional Director, Europe, Mundipharma International Ltd.  “Together with BioCryst, we share a common vision for bringing this promising therapy to market and addressing the needs of these patients.”

Under the terms of the agreement Mundipharma will obtain rights in markets across Europe, Asia and Australasia to Fodosine™ in the field of oncology in exchange for a $10 million up-front payment. Mundipharma will pay 50% of costs, up to an additional $10 million, on current trials of Fodosine™ and on a planned Phase IIb trial to be conducted by BioCryst.  Furthermore, Mundipharma will commit up to an additional $15 million to assist in the evaluation of Fodosine’s™ therapeutic safety and efficacy profile.  BioCryst may also receive future event payments totalling $155 million in addition to royalties on product sales of Fodosine™ by Mundipharma.  BioCryst will owe sublicense payments to third parties on the upfront payment and any future event payments and royalties on this PNP inhibitor.


For the next five years after the effective date of this alliance between Mundipharma and BioCryst, Mundipharma will have a right of first negotiation on any new PNP inhibitors BioCryst elects to develop in the area of oncology, except for the BioCryst compound BCX-4208.  BioCryst retains all rights to commercialize and promote Fodosine™ in the United States, and other countries outside the scope of this agreement.

BioCryst will sponsor a conference call at 8:30 a.m. Eastern U.S. Time on Thursday, February 2, 2006 to discuss today’s news in more detail. This call is open to the public and can be accessed live either over the Internet from the company’s website http://www.biocryst.com or by dialing 1-800-810-0924 (U.S.) or 1-913-981-4900 (international). No passcode is needed for the call.

*The agreement covers Europe and a number of other markets in Asia and Australasia including Japan, Australia, New Zealand, China and India.

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™, 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 was recently completed. 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™ is currently being studied in a Phase I trial with an oral formulation in cutaneous T-cell lymphoma (CTCL), a Phase II trial in chronic lymphocytic leukemia (CLL) and a Phase I/II trial in B-cell acute lymphoblastic leukemia (B-ALL). Fodosine™ 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-ALL. Additionally the FDA has granted “fast track” status to the development of Fodosine™ for the treatment of relapsed or refractory T-cell leukemia.

In November, 2005 BioCryst announced it had entered into an exclusive licensing agreement with Roche to develop and commercialize BCX-4208 for the prevention of acute rejection in transplantation and for the treatment of autoimmune diseases. 

Additionally, BioCryst has re-initiated clinical development of peramivir, an inhibitor of influenza neuraminidase, with a focus on intravenous and intramuscular delivery. In December 2005 BioCryst received approval from the FDA to begin human studies with intravenous peramivir.  In January 2006 the FDA granted fast track designation for peramivir injection in the treatment of influenza infections, including highly virulent, life-threatening strains of influenza. 

In its hepatitis C polymerase inhibitor program, BioCryst has identified a clinical candidate, BCX-4678, and is advancing this compound through preclinical testing with the goal of filing an IND in 2006.  For more information about BioCryst, please visit the company’s web site at http://www.biocryst.com.
