We believe the diligent efforts of our internal teams to achieve the resumption of our Phase 3 RAISE trial in refractory status epilepticus this month keeps us on track for this key trial, and our next generation formulation development will provide meaningful data this year for our next steps in new indications, such as Lennox-Gastaut syndrome,” said Scott Braunstein, M.D., Chief Executive Officer of Marinus Pharmaceuticals. “I look forward to building on the strong foundation we’ve established as we continue to grow the ganaxolone franchise to help patients suffering from rare epilepsies.”

Clinical Pipeline Update

Financial Updates

• In March 2022, Marinus received an additional $30 million in funding under the existing Oaktree Capital Management, L.P. (Oaktree) credit agreement. This additional funding became available as a result of the U.S. Food and Drug Administration’s (FDA) recent approval of ZTALMY.
• Marinus was awarded a rare pediatric disease priority review voucher (PRV) by the FDA in March 2022 as a result of the ZTALMY approval; Marinus remains committed to monetizing this PRV with plans actively underway.

Financial Results

• At March 31, 2022, the company had cash and cash equivalents of $126.3 million, compared to $122.9 million at December 31, 2021.
• Marinus recognized $14.2 million in revenue for the three months ended March 31, 2022, as compared to $1.8 million for the three months ended March 31, 2021. The increase in 2022 revenue was driven by a one-time revenue recognition of $12.7 million related to the previously received upfront payment, associated with our European collaboration with Orion Corporation, which is no longer subject to a clawback provision as a result of successful completion of required M2 metabolite testing. Excluding the Orion collaboration revenue, the company recognized $1.5 million in BARDA federal contract revenue for the three months ended March 31, 2022, as compared to $1.8 million in BARDA federal contract revenue for the three months ended March 31, 2021.
• Research and development expenses were $18.0 million for the three months ended March 31, 2022, compared to $18.6 million for the three months ended March 31, 2021; the decrease was due primarily to reduced CDD development and safety study activities partially offset by increased headcount costs and TSC clinical development costs.
• General and administrative expenses increased to $11.7 million for the three months ended March 31, 2022, compared to $10.4 million for the three months ended March 31, 2021; the primary drivers of the increase were increased support for scale up of the company’s operations as well as preparation for commercialization.
• A one-time cost of IP license fee of $1.2 million was recognized as expense during the three months ended March 31, 2022, associated with the recently signed agreement with Ovid Therapeutics to license patents and patent applications for the use of ganaxolone in the treatment of CDD.
• The company reported net losses of $19.4 million and $27.1 million for the three months ended March 31, 2022 and 2021, respectively; cash used in operating activities increased to $27.7 million for the three months ended March 31, 2022, compared to $16.2 million for the same period a year ago.

Readers are referred to, and encouraged to read in its entirety, the company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2022, to be filed with the Securities and Exchange Commission, which includes further detail on the company’s business plans, operations, financial condition, and results of operations.
