BioCryst Announces the Acceptance of Peramivir MAA Filing by the European Medicines Agency

RESEARCH TRIANGLE PARK, N.C., Jan. 30, 2017 -- BioCryst Pharmaceuticals, Inc. (NASDAQ:BCRX), a pharmaceutical company focused on the development and commercialization of treatments for rare diseases, announced today that the European Medicines Agency (EMA) has accepted the filing of its peramivir Marketing Authorization Application (MAA) for treatment of symptoms typical of influenza in adults 18 years and older.  The acceptance of the MAA begins the review process by the EMA under the centralized licensing procedure for all 28 member states of the European Union, Norway and Iceland. Peramivir’s efficacy has been demonstrated when treatment is initiated within two days of first onset of symptoms.

“This filing brings BioCryst and Seqirus one step closer to making the only single-dose, I.V. influenza therapy available to an important market, the European Union,” said Jon P. Stonehouse, President & Chief Executive Officer.    

Seqirus, a leader in influenza prevention through the supply of seasonal and pandemic influenza vaccines to global markets, will commercialize ALPIVAB^TM.

About Peramivir

Peramivir is an intravenous (I.V.) viral neuraminidase inhibitor approved in multiple countries, including the United States, for the treatment of influenza in patients who have been symptomatic for no more than two days. Efficacy of peramivir is based on clinical trials of naturally occurring influenza in which the predominant influenza infections were influenza A virus; a limited number of subjects infected with influenza B virus were enrolled. The efficacy of peramivir could not be established in patients with serious influenza requiring hospitalization. In clinical studies, side effects with peramivir were similar to placebo. The most common adverse reaction was diarrhea (peramivir 8% vs 7% placebo). Similar to other neuraminidase inhibitors, there is a risk of neuropsychiatric events (confusion, delirium) and serious skin reactions.
