Financial Update

At December 31, 2015, the Company had cash, cash equivalents and investments of $57.7 million, compared to $49.7 million at December 31, 2014.  The increase was primarily due to $28.1 million in net proceeds received in November 2015 from the closing of a public offering, offset by $20.1 million in cash used in operating activities.

Research and development expenses increased by $10.2 million, to $18.9 million, for the year ended December 31, 2015, compared to the same period of 2014. The increase resulted primarily from an increase in clinical, drug development and consulting costs related to ongoing clinical trials for ganaxolone, as well as increases in compensation-related costs due to hiring additional clinical resources.

General and administrative expenses increased by $2.3 million, to $5.5 million, for the year ended December 31, 2015, compared to the same period of 2014. The increase in general and administrative expenses was primarily due to the addition of new management team members and the upward scaling of our operations in connection with our ongoing Phase 3 clinical trial of ganaxolone in adults with drug-resistant focal onset epileptic seizures.

The Company reported net losses of $24.9 million and $10.8 million for the years ended December 31, 2015 and 2014, respectively.  Cash used in operating activities was $20.1 million for the year ended December 31, 2015 compared to $8.6 million for the same period a year ago.

Readers are referred to, and encouraged to read in its entirety the Company's Annual Report on Form 10-K for the year ended December 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 ganaxolone, which offers a new mechanism of action, demonstrated efficacy and safety and convenient dosing, to improve the lives of patients suffering from epilepsy and neuropsychiatric disorders.  Ganaxolone is a CNS-selective GABAA modulator that acts on a well-characterized target in the brain known to have both anti-seizure and anti-anxiety effects. Ganaxolone is being developed in three different dose forms (IV, capsule and liquid) intended to maximize therapeutic reach to adult and pediatric patient populations in both acute and chronic care settings.  Ganaxolone IV is planned to enter clinical trials in 2016 and is being developed to treat status epilepticus. Ganaxolone IV is complemented by its oral dose forms, providing the potential for IV-to-oral continuation therapy for patients transitioning from acute care to outpatient settings.  Ganaxolone capsule is being evaluated in a Phase 3 multi-national clinical trial as adjunctive treatment of focal onset seizures in adults.  Ganaxolone capsule and liquid are being studied in orphan pediatric indications with comorbidities in seizures and behavior disorders — PCDH19 epilepsy and Fragile X Syndrome.
