RESEARCH TRIANGLE PARK, N.C., Aug. 10, 2021 (GLOBE NEWSWIRE) — BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) announced today that it has withdrawn its proposed public offering. With our strong balance sheet, and increasing revenues from ORLADEYO® (berotralstat), we believe that current market conditions are not conducive to an offering on terms that would be in the best interests of our current stockholders. We are well capitalized, with cash, cash equivalents, restricted cash and investments of $222.8 million as of June 30, 2021. Based on our expectations for revenue, operating expenses, and our option to access an additional $75 million from our existing credit facility, we believe our current cash runway takes us into 2023. About BioCryst Pharmaceuticals BioCryst Pharmaceuticals discovers novel, oral, small-molecule medicines that treat rare diseases in which significant unmet medical needs exist and an enzyme plays a key role in the biological pathway of the disease. Oral, once-daily ORLADEYO® (berotralstat) is approved in the United States, the European Union, Japan and the United Kingdom for the prevention of HAE attacks in adults and pediatric patients 12 years and older.

RAPIVAB® (peramivir injection), a viral neuraminidase inhibitor for the treatment of influenza, has received regulatory approval in the U.S., Canada, Australia, Japan, Taiwan and Korea. Post-marketing commitments for RAPIVAB are ongoing.
