BioCryst Receives European Medicines Agency Approval for ALPIVAB™ for the Treatment of Influenza

RESEARCH TRIANGLE PARK, N.C., May 01, 2018 -- BioCryst Pharmaceuticals, Inc. (NASDAQ:BCRX), a pharmaceutical company focused on the development and commercialization of treatments for rare diseases, today announced that the European Medicines Agency (EMA) has approved peramivir with the brand name of ALPIVAB, a single intravenous (I.V.) infusion for the treatment of uncomplicated influenza in adults and children from the age of 2 years.

“ALPIVAB approval in the European Union represents a significant advancement for influenza patients, representing the only single dose I.V. treatment option in the armamentarium for influenza infections,” said Jon P. Stonehouse, President & Chief Executive Officer.

The EMA’s approval of ALPIVAB under the centralized licensing procedure provides marketing authorization for all 28-member states of the European Union, Norway and Iceland. Previously, peramivir injection (RAPIVAB^®, RAPIACTA^®, PERAMIFLU^®) has received approval for commercialization in the United States, Canada, Australia, Japan, Taiwan and Korea. 

BioCryst has a license agreement with Seqirus regarding peramivir. As we have previously disclosed, BioCryst and Seqirus are engaged in a formal dispute resolution process.  The dispute involves many items under the contract including, but not limited to, the EMA approval milestone of $5 million dollars, which BioCryst maintains is now due under the parties’ agreement.
