RADNOR, Pa., May 01, 2017 (GLOBE NEWSWIRE) -- Marinus Pharmaceuticals, Inc. (Nasdaq:MRNS) (the "Company"), a biopharmaceutical company dedicated to the development of innovative therapeutics to treat epilepsy and neuropsychiatric disorders, today provided a business update and reported its financial results for the quarter ended March 31, 2017.

Near-term Clinical Value Catalysts (unchanged)

  • Initiate Phase 2 study in women with postpartum depression (PPD) in 1H 2017 
  • Report top-line data from children with genetic seizure disorders in mid-2017 
  • Initiate Phase 2 study in patients with status epilepticus (SE) in 2H 2017 

"We have directed our strategy towards indications where we believe there is both a significant unmet medical need and expected therapeutic benefit from ganaxolone's GABAA modulation mechanism," said Christopher M. Cashman, chief executive officer of Marinus Pharmaceuticals.  "With the recent addition of Dr. Lorianne Masuoka as chief medical officer, our clinical leadership is in place to execute on our strategy and vision to improve the lives of patients and their families suffering from seizures, depression and anxiety disorders."

Recent Publications and Presentations

  • Publication of ganaxolone data in the January issue of Neuropharmacology showing reduction in seizures and improvement in behaviors in a preclinical model of Angelman syndrome. 
  • Platform presentation at the American Academy of Neurology annual meeting of the clinical data from the double-blind, placebo-controlled, cross-over trial evaluating ganaxolone in children and adolescents with Fragile X Syndrome (FXS). Patients enrolled in the study with a higher level of anxiety at baseline showed separation between ganaxolone and placebo in anxiety and positive trends in improvement in attention and hyperactivity. 
  • Presentation of ganaxolone Phase 1 data at the biannual London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures and selection as a Best Poster for publication in Epilepsia. The phase 1 clinical data showed that ganaxolone IV was generally safe, well-tolerated and reached targeted dose levels in a short period of time. 

Financial Update

At March 31, 2017, the Company had cash, cash equivalents and investments of $24.8 million, compared to $30.1 million at December 31, 2016.  The Company believes that its cash, cash equivalents and investments, as of March 31, 2017, are adequate to fund operations into the second half of 2018.

Research and development expenses decreased to $3.6 million for the three months ended March 31, 2017, as compared to $5.5 million for the same period in the prior year.  The decrease was primarily due to a decrease of $2.9 million associated with our drug-resistant focal onset seizures program, which discontinued in June 2016.  The decrease was partially offset by an increase of $0.7 million associated with our IV programs in PPD and SE. 

General and administrative expenses increased to $1.8 million for the three months ended March 31, 2017, as compared to $1.6 million for the same period in the prior year.

Cash used in operating activities increased to $6.8 million for the three months ended March 31, 2017 compared to $6.1 million for the same period in the prior year. The increase was driven primarily by a net increase in the change in operating assets and liabilities of $2.6 million, partially offset by a decrease in net loss of $1.8 million. 

Readers are referred to, and encouraged to read in its entirety, the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2017 filed with the Securities and Exchange Commission, which includes further detail on the Company's business plans and operations, financial condition and results of operations.
