AMRN Amarin Corp PLC

On May 31, 2016, the U.S. Food and Drug Administration (FDA) advised Amarin Corporation plc (Amarin) that it has determined that Vascepa ^® (icosapent ethyl) capsules are eligible for five-year, new chemical entity (NCE) marketing exclusivity pursuant to the Hatch-Waxman Amendments to the U.S. Federal Food, Drug, and Cosmetic Act. This determination provides Vascepa with the benefits of NCE exclusivity afforded by statute. Under the statute, NCE exclusivity for Vascepa runs from its date of FDA approval on July 26, 2012 and extends until July 26, 2017. The statutory 30-month stay triggered by patent litigation following generic application submissions permitted on July 26, 2016 would expire on January 26, 2020, seven and one-half years from FDA approval.
