Adding to the antiviral drug mix for people who are infected by the H1N1 "swine flu" is an injection called Peramivir by BioCryst Pharmaceuticals, Inc. Please note that Peramivir is UNAPPROVED for use and only an emergency declaration allows its use.
Commonly reported adverse events in Peramivir IV clinical trials were diarrhea, nausea, vomiting, and neutropenia. Additional adverse events associated with the drug, some of which may be serious, may become apparent with more widespread use.
Although not observed in clinical trial data available to date Peramivir IV may be associated with rare cases of anaphylaxis and serious skin reactions and a variety of neurologic and behavioral symptoms that have been reported with other neuraminidase inhibitors.

Emergency Use Authorization Granted For BioCryst's Peramivir
BIRMINGHAM, Ala., Oct. 23 /PRNewswire-FirstCall/ -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced that the U.S. Food and Drug Administration (FDA), in response to a request from the U.S. Centers for Disease Control and Prevention (CDC), has issued an emergency use authorization (EUA) for the investigational anti-viral drug intravenous (i.v.) peramivir in certain adult and pediatric patients with confirmed or suspected 2009 H1N1 influenza infection who are admitted to a hospital.
Specifically, i.v. peramivir is authorized only for hospitalized adult and pediatric patients for whom therapy with an i.v. drug is clinically appropriate, based on one or more of the following reasons:
1. the patient is not responding to either oral or inhaled anti-viral therapy, or
2. when drug delivery by a route other than an intravenous route -- e.g., enteral (absorbed by the intestines) or inhaled -- is not expected to be dependable or feasible;
3. for adults only, when the clinician judges i.v. therapy is appropriate due to other circumstances.
Additional information regarding the peramivir EUA is available on the Web at:
In advance of any U.S. Government order that may come from the ongoing request for proposal (RFP) negotiations, BioCryst has donated and transferred to the Department of Health and Human Services (HHS) an initial supply sufficient for 1,200 courses of i.v. peramivir 600 mg once-daily for five days. This transfer was made under the development contract with HHS to allow doctors and patients near-term access to the drug, and is separate from the RFP process.
"The issuance of this EUA is important because it makes peramivir a treatment option for physicians in the U.S. during the ongoing influenza health emergency," said Jon P. Stonehouse, Chief Executive Officer at BioCryst. "BioCryst has worked with HHS to enable the Government to rapidly deploy an initial supply of peramivir, and we are prepared to deliver more."
To prepare for peramivir orders that BioCryst may receive from the U.S. or other governments during this pandemic emergency, BioCryst is completing production of approximately 130,000 courses of i.v. peramivir and is prepared to make more, if required.
Peramivir is an anti-viral agent that was discovered by BioCryst which 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 pandemic H1N1 swine flu origin viral strains. Peramivir has been studied in patients with complicated and uncomplicated influenza. BioCryst's partner, Shionogi & Co., Ltd. is currently preparing to file for regulatory approval in Japan this year.
BioCryst Pharmaceuticals designs, optimizes and develops novel small-molecule pharmaceuticals that block key enzymes involved in infectious diseases, cancer and inflammatory diseases. BioCryst has progressed two novel compounds into late-stage pivotal clinical trials; peramivir, an anti-viral for influenza, and forodesine, a purine nucleoside phosphorylase (PNP) inhibitor for cutaneous T-cell lymphoma (CTCL). Utilizing crystallography and structure-based drug design, BioCryst continues to discover additional compounds and to progress others through pre-clinical and early development to address the unmet medical needs of patients and physicians. The Company's strategic alliances with the U.S. Department of Health and Human Services, Shionogi & Co., Ltd., Green Cross Corporation and Mundipharma International Holdings Limited validate its scientific foundation and the utility of its product candidates.
