FOR IMMEDIATE RELEASE

BIOCRYST REPORTS FOURTH QUARTER AND FULL YEAR 2006
FINANCIAL RESULTS

Birmingham, Alabama — February 7, 2007 —BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced financial results for the quarter and year ended December 31, 2006.

Fourth Quarter Results
The Company reported a net loss of $10.1 million, or $0.34 per share, for the fourth quarter of 2006, compared to a net loss of $7.2 million, or $0.27 per share, for the fourth quarter of 2005.

For the three months ended December 31, 2006, the Company reported revenue of $2.1 million as compared to $0.02 million for the three months ended December 31, 2005. Revenues for the fourth quarter of 2006 increased primarily due to amounts earned pursuant to our collaboration agreements with Mundipharma International Holdings Limited (Mundipharma) and Roche and the continuing amortization of the upfront payments from those agreements.

R&D expenses for the fourth quarter of 2006 were $11.2 million as compared to $6.0 million for the same period in 2005. The increase is primarily attributable to the clinical and manufacturing costs of our expanded peramivir and Fodosine™ programs, increases in personnel and related costs to support the clinical development of the Company’s pipeline, plus a $0.5 million non-cash share-based compensation charge. Statement of Financial Accounting Standards No. 123(R) (“SFAS 123R”) was adopted by the Company on January 1, 2006.

G&A expenses for the fourth quarter of 2006 were $1.6 million, compared to $1.5 million in the same period of 2005. An increase of $0.6 million in share-based compensation expense more than offset decreases in professional fees and other personnel costs.

At December 31, 2006, cash, cash equivalents and investments totaled $46.2 million.

Year-End Results
The Company reported a net loss of $43.6 million, or $1.50 per share, for 2006, compared with a net loss of $26.1 million, or $1.01 per share for 2005.

The Company reported revenue of $6.2 million in 2006 compared to $0.2 million in 2005. Revenues for 2006 include amounts earned during the year pursuant to our collaboration agreements and the continuing amortization of the upfront payments from those agreements.

R&D expenses for 2006 were $47.1 million as compared to $23.6 million in 2005. The reasons for the increase in R&D expenses for the twelve month periods are essentially the same as those discussed for the comparable quarters. The share-based compensation charge included in R&D expense during 2006 was $1.5 million.

G&A expenses for 2006 were $6.1 million compared to $3.7 million in 2005. The primary reasons for the increase in G&A expenses were the share-based compensation charge of $1.8 million, and increases in personnel related costs and professional fees.

2006 and Recent Corporate Highlights

•	Initiated Pivotal Phase IIb Fodosine™ Clinical Trial In January, 2007, BioCryst initiated a pivotal phase IIb clinical trial with Fodosine™, in the treatment of patients with relapsed or refractory T-cell leukemia/lymphoma. Initiation of this trial triggered a $5 million event payment from Mundipharma to BioCryst under the terms of the collaboration established in February, 2006.
	The multicenter, open-label, non-randomized, repeat-dose registration study will be conducted in accordance with a Special Protocol Assessment (SPA) agreement between the U.S. Food and Drug Administration (FDA) and BioCryst and will test a combination of intravenous and oral formulations of Fodosine™. Designed to determine the rate of complete remission achieved with this regimen of Fodosine™, the multinational trial will include sites in the United States, Eastern and Western Europe, and South America.
	This trial builds on earlier studies, from which, data were presented during 2006 at the American Society of Hematology and the American Association for Cancer Research meetings.
•	Initiated Phase II Peramivir Clinical Trial Additionally, in January, 2007, BioCryst initiated a Phase II clinical trial of peramivir, the company’s lead influenza neuraminidase inhibitor, to determine the safety and efficacy of an intramuscular formulation of the drug in patients with influenza. The double-blind, placebo-controlled trial will enroll patients with acute influenza at sites in North America, Europe and Southeast Asia. Two different doses of peramivir will be tested.
	This most recent study is based on the positive Phase I clinical data obtained in 2006 and reported at the 46th Annual ICAAC meeting in September 2006.

• Awarded $102.6 Million Four-Year Contract from HHS for Development of Peramivir

The award is part of a larger DHHS initiative to pursue the development of new therapies and vaccines which may expand the ability of the United States to respond quickly to a potential pandemic.
