Seek Plaintiff


A class action lawsuit has been filed against Marinus Pharmaceuticals, Inc. (“Marinus” or the “Company”) (NASDAQ: MRNS) and certain of the Company’s former senior executive officers alleging violations of the federal securities laws.  The Marinus class action lawsuit is brought on behalf of all persons and entities who purchased or otherwise acquired publicly traded Marinus securities between March 17, 2021 and May 7, 2024, both dates inclusive (the “Class Period”).  Investors have until August 5, 2024 to seek appointment as lead plaintiff of the Marinus class action lawsuit.

Marinus describes itself as a commercial-stage pharmaceutical company dedicated to the development of innovative therapeutics for the treatment of seizure disorders, including rare genetic epilepsies and status epilepticus, which includes the use of ZTALMY® (ganaxolone).

Pertinent to the class action lawsuit is the Randomized Therapy in Status Epilepticus trial (“RAISE”), which the Company has described as a “pivotal Phase 3 trial in refractory status epilepticus (RSE) patients.”

The Marinus class action lawsuit alleges that Defendants, throughout the Class Period, made materially false and/or misleading statements and/or failed to disclose that: (1) Defendants understated the risk of failure to meet the early-stopping criteria in the RAISE trial; (2) Defendants did not disclose that a possible consequence of failing to meet the early stopping criteria in the RAISE trial would be that Marinus would stop the separate Phase 3 RAISE II trial; and (3) as a result, Defendants’ statements about their business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all times.  When the true details entered the market, the lawsuit claims that investors suffered damages.
