BioCryst Pharmaceuticals Provides Update Regarding Peramivir
RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)-- BioCryst Pharmaceuticals, Inc. (NAS: BCRX) today announced that it received a preliminary comment letter from the U.S. Food & Drug Administration (FDA) that outlines a pathway by which BioCryst could file a New Drug Application (NDA) seeking regulatory approval of intravenous (i.v.) peramivir. The letter was sent in response to questions BioCryst submitted to the FDA in advance of an upcoming Type C regulatory meeting regarding i.v. peramivir. The FDA also suggested the Company request a pre-NDA meeting to reach agreement on a complete NDA submission and to address review issues identified in its preliminary comment letter.
BioCryst also received written notification from the Department of Health and Human Services in the form of a Stop-Work Order directing the Company to cease work on peramivir under its U.S. Government contract, except for certain activities primarily related to the upcoming FDA Type C meeting which is scheduled. The notification confirmed that the Biomedical Advanced Research and Development Authority (BARDA/HHS) will continue to support and fund certain activities that are necessary to achieve immediate milestones, as well as activities deemed essential to maintain compliance with FDA regulations or to fulfill pending FDA requests. Following an In-Process Review (IPR) meeting, which BioCryst anticipates in the second quarter, BARDA/HHS is expected to determine the path forward for the contract.
"We are encouraged by these recent communications, and we look forward to advancing our peramivir discussions with the FDA and BARDA/HHS. Our ultimate objective is the approval of peramivir as an intravenous treatment option that could benefit patients in the United States," said Jon P. Stonehouse, President & Chief Executive Officer. "The Stop-Work Order is understandable, as it focuses the scope of reimbursable activities to those that are essential and supportive to continuing regulatory communications, with the objective of preparing an NDA submission. If the conversations with the FDA and BARDA/HHS are successful, BioCryst stands ready to file an NDA for peramivir as soon as feasible."
The influenza virus causes an acute viral disease of the respiratory tract. Unlike the common cold and some other respiratory infections, seasonal flu can cause severe illness, resulting in life-threatening complications. According to the CDC, an estimated 5% to 20% of the American population suffers from influenza annually, and there are approximately 3,000 to 49,000 flu-related deaths per year in the U.S. Most at risk are young children, the elderly and people with seriously compromised immune systems.
Peramivir is a potent, intravenously administered investigational 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 flu viral strains. Peramivir is being developed under a $234.8 million contract from HHS/BARDA. In January 2010, Shionogi & Co., Ltd. launched intravenous (i.v.) 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 i.v. peramivir in Korea to treat patients with influenza A & B viruses, including H1N1 and avian influenza.
