Marinus Pharmaceuticals Provides Business Update and Reports First Quarter 2015 Financial Results

RADNOR, Pa., May 11, 2015 (GLOBE NEWSWIRE) -- Marinus Pharmaceuticals, Inc. (Nasdaq:MRNS), a biopharmaceutical company dedicated to the development of innovative epilepsy and other neuropsychiatric therapeutics, today provided a business update and announced its financial results for the first quarter ended March 31, 2015.

"We started 2015 with a goal to broaden the potential therapeutic reach of ganaxolone by pursuing orphan indications and the acute care market," commented Christopher M. Cashman, Chairman and CEO of Marinus Pharmaceuticals. "To that end, in the first quarter, we initiated a Phase 2 clinical trial with ganaxolone in PCDH19 female pediatric epilepsy, which just recently received orphan drug designation from FDA. We are also completing the requisite pre-clinical work to bring intravenous ganaxolone to the clinic as a complement to our existing oral formulations, offering continuity of care from the hospital to outpatient settings. We are excited about reaching our near-term clinical development milestones, which we believe will demonstrate ganaxolone's clinical utility in addressing important unmet and underserved therapeutic areas."

Upcoming Milestones for 2015

First Quarter Financial Update

At March 31, 2015, the Company had cash, cash equivalents and investments of $46.0 million, compared to $49.7 million at December 31, 2014. The Company believes that its cash, cash equivalents and investments, as of March 31, 2015, are adequate to fund operations into the second half of 2016.

Research and development expenses increased to $5.5 million for the three months ended March 31, 2015, as compared to $2.1 million for the same period in the prior year. The increase was primarily due to the increase in clinical costs related to our ongoing clinical trial of ganaxolone in patients with focal onset seizures, as well as hiring additional clinical resources including our Chief Medical Officer. Substantially all research and development expenses relate to our clinical trial in focal onset epileptic seizures.

General and administrative expenses increased to $1.4 million for the three months ended March 31, 2015, as compared to $0.5 million for the same period in the prior year. The increase in general and administrative expenses was primarily due to the hiring of new management and the upward scaling of our operations in connection with both becoming a public company and our ongoing clinical trial of ganaxolone in patients with focal onset seizures.

Marinus reported net losses of $7.0 million and $2.2 million for the three months ended March 31, 2015 and 2014, respectively. Cash used in operating activities was $4.0 million for the three months ended March 31, 2015 compared to $1.1 million for the same period a year ago.

Readers are referred to, and encouraged to read in their entirety, the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2015 to be filed with the Securities and Exchange Commission, which includes further detail on the above-referenced transactions and the Company's business plans and operations, financial condition and results of operations.

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.
