ROCKVILLE, Md., Oct. 15, 2015 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq:SUPN) announced that it has entered into a settlement agreement with Par Pharmaceutical Companies, Inc. and Par Pharmaceutical, Inc. (collectively "Par") involving the ongoing patent litigation regarding Par's filing of an Abbreviated New Drug Application (ANDA) seeking approval to market a generic version of Supernus' Trokendi XR® (extended-release topiramate) capsules. The settlement permits Par to begin selling a generic version of Trokendi XR® on April 1, 2025, or earlier under certain circumstances. The agreement is subject to entry of a consent judgment by the U.S. District Court for the District of New Jersey.

The agreement will be submitted to the applicable governmental agencies.

The patent litigation continues against Actavis and Zydus, the other two ANDA filers. Patent protection for Trokendi XR® expires no earlier than 2027 and Supernus intends to continue its vigorous enforcement of its patent rights.

Supernus is represented by attorneys from Frommer Lawrence and Haug LLP and its corporate counsel, Saul Ewing LLP.
