RADNOR, Pa.--(BUSINESS WIRE)--Marinus Pharmaceuticals, Inc. (Nasdaq: MRNS), a pharmaceutical company dedicated to the development of innovative therapeutics to treat seizure disorders, is today hosting an Investor and Analyst Event in New York to review the Company’s ongoing clinical-stage programs and commercial planning activities. The event begins at 9 a.m. ET and will be available via webcast here.
“I look forward to showcasing how we are planning to deliver on our commitment to improve the lives of more patients with refractory seizure disorders during today’s Investor and Analyst Event,” said Scott Braunstein, M.D., Chairman and Chief Executive Officer of Marinus. “The presentations will offer a deep dive on the significant progress being made advancing our late-stage clinical programs and commercial preparation activities that we believe could expand the treatment potential of ganaxolone into additional disease states which have limited therapeutic alternatives for patients today. We will also highlight the ongoing success of our first product launch in CDKL5 deficiency disorder, with continued growth in new commercial patients and strong payer reimbursement.”
Dr. Braunstein continued, “Enrollment in the Phase 3 RAISE trial in refractory status epilepticus has been on an upward trajectory since early August following the activation of new clinical sites. Importantly, we have extended our cash runway into the fourth quarter of 2024 through strategic use of our existing ATM facility. This is expected to provide us with the resources needed to successfully execute on our two Phase 3 data readouts in RSE and tuberous sclerosis complex and invest in the appropriate pre-commercial activities to continue driving future growth for Marinus.”
Rajat Dhar, M.D., Professor of Neurology in the Section of Neurocritical care at Washington University School of Medicine in St. Louis, Attending Physician in the Neurology/ Neurosurgery Intensive Care Unit at Barnes-Jewish Hospital, and investigator in the RAISE trial, who will provide an overview on the unmet need in status epilepticus, noted, “Patients with status epilepticus often require hospitalization and treatment as neurological emergencies, with more than 50% unresponsive to first- or second-line therapies. As a result, this patient population is long overdue for treatment options that have the potential to improve morbidity and mortality.”
Highlights from today’s presentations are summarized below.
- Company expects third quarter 2023 ZTALMY® (ganaxolone) oral suspension CV net product revenues of between $5 and $5.2 million
- Continued growth in commercial patients with approximately 140 patients active on therapy as of September 2023
- On track to meet full year 2023 expected ZTALMY net product revenues of between $17 and $18.5 million
Ganaxolone Clinical Update
Refractory Status Epilepticus
- Over 70% of patients required for the interim analysis are now enrolled in the Phase 3 RAISE trial of intravenous (IV) ganaxolone in refractory status epilepticus
- RAISE enrollment trends have returned to anticipated levels with enrollment for the interim analysis expected to conclude by January 2024
- Topline data continues to be anticipated in the first quarter of 2024, if the pre-defined stopping criteria from the planned interim analysis are met
Ganaxolone development in the RAISE trial is being funded in part by the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response at the U.S. Department of Health and Human Services, under contract number 75A50120C00159.
Tuberous Sclerosis Complex
A protocol amendment for Marinus’ ongoing Phase 3 TrustTSC trial of oral ganaxolone in tuberous sclerosis complex (TSC) has been finalized
- The trial is now anticipated to enroll 128 patients and is designed to provide 90% power to detect a 25% reduction in TSC-associated seizure frequency
- Total blinded discontinuation rates to date remain below 10%, with discontinuations due to somnolence less than 5%
- Topline data continues to be expected in mid-2024
General Business and Financial Update
Subsequent to the financial results reported on August 10, 2023, a total of 3.7 million shares were sold through the Company’s at-the-market (ATM) facility contributing net proceeds of $25.9 million
- ATM sales consisted of a limited number of discreet reverse inquiry transactions from existing shareholders
- Inclusive of the proceeds from the recent ATM offering, the Company projects cash, cash equivalents, and short-term investments at the end of the third quarter of 2023 to be in the range of between $170 and $175 million. This balance is projected to be sufficient to fund the Company’s operating expenses, capital expenditure requirements, and maintain the minimum cash balance of $15 million required under the Company’s debt facility into the fourth quarter of 2024.
