About RAPIVAB

RAPIVAB is a potent, intravenously administered, investigational anti-viral agent that rapidly delivers high plasma concentrations to the sites of influenza infection. If approved, RAPIVAB would be the first and only one-dose intravenous treatment for acute, uncomplicated influenza in the U.S. In laboratory tests, RAPIVAB has shown activity against multiple influenza strains, including H7N9 and pandemic H1N1 swine flu viral strains. RAPIVAB was developed under a $234.8 million contract from BARDA/HHS. In January 2010, Shionogi & Co., Ltd. launched peramivir in Japan under the name RAPIACTA^® to treat patients with influenza and in August 2010, Green Cross Corporation announced that it had received marketing and manufacturing authorization for peramivir in Korea to treat patients with influenza A & B viruses, including H1N1 and avian influenza.
