RESEARCH TRIANGLE PARK, N.C.--([ BUSINESS WIRE ])--BioCryst Pharmaceuticals, Inc. (NASDAQ: BCRX) today announced the presentation of new data related to the efficacy and safety of BCX4208 for the treatment of gout at the 74^th ACR Scientific Meeting being held in Atlanta, Georgia.

"Effects of a Purine Nucleoside Phosphorylase Inhibitor, BCX4208, on the Serum Uric Acid Concentrations in Patients with Gout"

The data will be presented during a poster session scheduled for today, November 8, 2010 from 9:00-11:00 a.m. Eastern Time. The poster to be presented during the session is entitled:

• aEffects of a Purine Nucleoside Phosphorylase Inhibitor, BCX4208, on the Serum Uric Acid Concentrations in Patients with Gouta. This poster concludes that BCX4208 doses administered at 40, 80, 120, 160 and 240 mg once-daily monotherapy rapidly and significantly reduced serum uric acid (sUA) in patients with gout. BCX4208 was generally safe and well-tolerated at the doses evaluated in this study.

About BCX4208

BCX4208 is a next generation purine nucleoside phosphorylase (PNP) inhibitor with the potential for once-a-day dosing suitable for chronic administration. With its unique mechanism of action, clinical activity and safety in clinical studies to date as well as its potential synergy with approved therapies, BCX4208 has the potential to address unmet medical needs across a broad spectrum of inflammatory and autoimmune diseases. In September 2010, BioCryst reported positive results from its Phase 2 study of BCX4208 alone and in combination with allopurinol in patients with gout, announcing that the study met its primary endpoint related to serum uric acid (sUA) reduction, demonstrated a dose-response for both BCX4208 and allopurinol, and that the combination of BCX4208 and allopurinol was shown to be superior to either drug alone in sUA reduction.
