Biocryst Pharmaceuticals and moksha8 Announce Approval for the Importation & Use of peramivir in Mexico

BIRMINGHAM, Ala., Jan. 12 /PRNewswire-FirstCall/ -- BioCryst Pharmaceuticals, Inc. today announced that moksha8 has been granted approval from COFEPRIS (The Federal Commission for the Protection against Sanitary Risk) in Mexico for the importation and use of peramivir in patients with influenza associated with the 2009 H1N1 influenza A strain. moksha8 has informed BioCryst that it has also filed for regulatory approval of peramivir in Brazil. Peramivir is the only intravenous (i.v.) anti-viral that is currently available under an Emergency Use Authorization (EUA) in the U.S. in certain adult and pediatric patients with confirmed or suspected 2009 H1N1 influenza A infection who are admitted to a hospital.

"Bringing important novel products to patients in need in Mexico and Brazil is core to our vision," said Ayse Kocak, Head of moksha8 in Mexico. "The rapid approval of peramivir for importation and use is a strong validation of the Mexican Government's commitment to public health."

Mexico is the fifth country to order or authorize use of peramivir during this flu season. The other countries include the U.S., Israel, Australia and South Korea.

Peramivir is a potent, intravenously administered anti-viral agent that rapidly delivers high plasma concentrations to the sites of infection. Discovered by BioCryst, peramivir inhibits the interactions of influenza neuraminidase, an enzyme which is critical to the spread of influenza within a host. In laboratory tests, peramivir has shown activity against multiple influenza strains, including pandemic H1N1 swine origin flu viral strains. Peramivir has been studied in over 1800 patients with complicated and uncomplicated influenza. Shionogi & Co., Ltd. and Green Cross Corp. have filed for regulatory approval in Japan and Korea respectively. On October 23, 2009, BioCryst announced that the U.S. Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for i.v. peramivir in certain adult and pediatric patients with confirmed or suspected 2009 H1N1 influenza A infection who are admitted to a hospital. Additional information regarding the peramivir EUA is available on the web at: http://www.cdc.gov/h1n1flu/eua/.
