Rapivab is a single-dose drug, and BioCryst said it is the first new antiviral influenza treatment to get marketing approval in 15 years.

Shares of BioCryst Pharmaceuticals Inc. rose 17 cents to $11.33 in morning trading.
The company received about $235 million from the U.S. Department of Health and Human Services to help fund studies of Rapivab. BioCryst said this is its first U.S. marketing approval for a drug it discovered.
Rapivab, or peramivir, was approved in Japan and South Korea in 2010 and is marketed in Japan by Shionogi and Co. It is only available in Korea on a limited basis.
