Law Offices of Howard G. Smith announces an investigation on behalf of Supernus Pharmaceuticals, Inc. (“Supernus” or the “Company”) (NASDAQ: SUPN) investors concerning the Company’s possible violations of federal securities laws.

On April 8, 2024, Supernus announced that the FDA had issued a Complete Response Letter (“CRL”) in response to the Company’s New Drug Application for its Parkinson’s disease treatment, SPN-830. The CRL stated that “the review cycle for the application is complete, but that the application is not ready for approval in its present form." Specifically, “two areas that require additional review by the FDA or additional information to be provided to the FDA," respectively relating to product quality and the master file for the infusion device.

On this news, Supernus’s stock price fell $2.12, or 6.3%, to close at $31.43 per share on April 8, 2024, thereby injuring investors.
