ROCKVILLE, Md., May 15, 2020 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN), a pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today announced that on May 14, 2020 the Company received a Paragraph IV Notice Letter from Apotex Inc.  and Apotex Corp advising Supernus of the submission by Apotex of an Abbreviated New Drug Application to the U.S. Food and Drug Administration (FDA) seeking approval for oxcarbazepine extended-release tablets. Supernus is currently reviewing the details of this Notice Letter and intends to vigorously enforce its intellectual property rights (IPR) relating to Oxtellar XR.
