News Release - November 19, 2007
IMPAX Comments on Lawsuit Related to Generic Version of Opana(R) ERHAYWARD, Calif.--(HSMN NewsFeed)--IMPAX Laboratories, Inc. (OTC:IPXL ) today confirmed that Endo Pharmaceuticals Holdings Inc. and Penwest Pharmaceuticals Co. have filed a lawsuit against the Company in the United States District Court for the District of Delaware alleging patent infringement related to IMPAX's filing of an Abbreviated New Drug Application (ANDA) with the U.S. Food and Drug Administration (FDA) for oxymorphone hydrochloride extended-release tablets CII, a generic version of Opana® ER.
“We believe that our Paragraph IV certification for generic Opana ER was proper, that our product does not infringe any valid, enforceable patent, and, as such, we will vigorously defend this lawsuit. Furthermore, we believe that the rescission of our ANDA by the FDA was inappropriate and we are continuing to work with the FDA to allow our ANDA to stand,” said Larry Hsu, Ph.D., president and chief executive officer of IMPAX Laboratories.
Endo Pharmaceuticals Holdings Inc. and Penwest Pharmaceuticals Co. manufacture and market Opana ER for the treatment of moderate to severe pain. According to Wolters Kluwer Health, U.S. sales of Opana ER tablets were approximately $48.8 million in the 12 months ended September 30th, 2007.
