BioCryst’s RAPIVAB® (peramivir injection) Recei

RESEARCH TRIANGLE PARK, N.C., Sept. 21, 2017 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (NASDAQ: BCRX ) a biotechnology company focused on the development and commercialization of treatments for rare and infectious diseases, announced today that the U.S. Food and Drug Administration (FDA) has approved a supplemental New Drug Application for RAPIVAB (peramivir injection), an intravenous (i.v.) neuraminidase inhibitor, extending its availability for the treatment of acute uncomplicated influenza to pediatric patients 2 years and older who have been symptomatic for no more than two days. The pediatric approval was based on the interim analysis of an ongoing pediatric clinical study. Those results will be presented at the upcoming ID Week 2017 meeting in San Diego.

“This approval represents the first new influenza antiviral for pediatric use in over 10 years,” said Jon P. Stonehouse, President & Chief Executive Officer.  “RAPIVAB provides another treatment option for pediatric patients with acute, uncomplicated influenza and represents another important milestone for BioCryst.”

“RAPIVAB is a great addition to our armamentarium of antiviral agents to combat influenza,” said John A. Vanchiere, MD, PhD, Chief, Section of Pediatric Infectious Diseases at LSU Health Sciences Center.  “It will be especially helpful for patients who cannot tolerate oral medications.  In addition, the long half-life allows for one-time dosing which will improve compliance.”
