Orexigen Announces Favorable Decision from U.S. District Court in Patent Litigation, Confirming Exclusivity for Contrave Through 2030

SAN DIEGO, Oct. 13, 2017 /PRNewswire/ -- Orexigen Therapeutics, Inc. (Nasdaq: OREX) announced today that the United States District Court for the District of Delaware issued a ruling in favor of Orexigen in the paragraph IV litigation against Actavis Laboratories FL, Inc. (Actavis) for three patents for Contrave® (naltrexone HCl / bupropion HCl extended release) with exclusivity through 2030.

"Orexigen's intent was to vigorously defend our intellectual property and we are very pleased with the Court's decision upholding the validity of all of the patents involved in the case," said Michael Narachi, President and CEO of Orexigen. "The Court's positive decision allows Orexigen to continue to fulfill its mission to provide innovative medicine to treat patients who are overweight or struggling with obesity."

Narachi added, "As we progress on our path to profitability by 2019, we expect that exclusivity through 2030 will provide many valuable years of growing profitability for Contrave."

Orexigen filed the lawsuit in response to an Abbreviated New Drug Application (ANDA) filed by Actavis, which sought to market and sell a generic version of the currently approved dose of Contrave tablets, prior to the expiration of U.S. patents listed in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book.  The ruling applied to Orexigen's two U.S. patents known as the Weber-Cowley patents (U.S. patents 7,375,111 and 7,426,626), which expire in 2024 and 2025, as well as the dissolution patent (U.S. patent 8,916,195), which expires in 2030.
