News Release Details

ROCKVILLE, Md., April 05, 2017 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq:SUPN), a specialty pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system diseases, today announced that the Food and Drug Administration (FDA) has granted final approval to the Company's Supplemental New Drug Applications (sNDAs) requesting a label expansion for Trokendi XR to include prophylaxis of migraine headache in adults and adolescents 12 years and older. Supernus was granted tentative approval of one of the two sNDAs in August 2016, with final approval subject to the pediatric exclusivity of the innovator's drug in the adolescent population, which expired March 28, 2017.

Based on IMS prescription data, Topiramate is the most prescribed drug for the treatment of migraine prophylaxis with more than 9 million prescriptions annually. This represents approximately 50% of all IMS prescriptions written for migraine prophylaxis.

"This approval and our imminent launch in migraine represent an opportunity for Supernus to further strengthen its leadership position in this market with Trokendi XR," stated Jack Khattar, President and Chief Executive Officer of Supernus Pharmaceuticals. "Trokendi XR, with its novel formulation, provides full 24 hour coverage for patients with smooth pharmacokinetics compared to the immediate-release topiramate products, making it an important new treatment option for adult and adolescent patients suffering from migraine headache. This is an important advancement for patients and another step towards realizing the full potential of Trokendi XR."
