About Marinus Pharmaceuticals

Marinus Pharmaceuticals, Inc., is a biopharmaceutical company dedicated to the development of innovative neuropsychiatric therapeutics. The Company's clinical stage drug candidate for the treatment of seizure disorders in adults and children with epilepsy is ganaxolone. Ganaxolone is a novel synthetic analog of the endogenous neurosteroid, allopregnanolone (known for its anticonvulsive and antianxiety effects) and was designed to avoid hormonal side effects associated with endogenous neurosteroids. The Company is currently conducting a multi-national, randomized, placebo-controlled, Phase 3 clinical trial to evaluate ganaxolone as adjunctive treatment of partial-onset seizures in adults. Ganaxolone is also being studied in a Phase 2 proof-of-concept clinical study for the treatment of the rare, genetic disorder, PCDH19 female pediatric epilepsy. To complement the existing formulations and to provide continuity of care, the Company is developing an IV formulation of ganaxolone for use in the hospital setting to control epileptic seizures. In addition, ganaxolone is being evaluated in a Phase 2 proof-of-concept investigator-sponsored clinical trial as a treatment for behaviors in Fragile X Syndrome.
