Marinus Pharmaceuticals Inc. (NASDAQ:MRNS) Meets FDA Specific Protocol Questions For Commencement Of RAISE Study

Marinus Pharmaceuticals Inc. (NASDAQ:MRNS) has announced the fulfillment of the FDA’s protocol-specific questions for its registration third phase RAISE trial in refractory status epilepticus (RSE). This allows the company to commence enrolment in the clinical trial.

Marinus to commence enrolment in RAISE study

The company submitted a protocol amendment in July to the FDA for the study for using IV ganaxolone in treating RSE. After its recent meeting with the FDA, Marinus expects to commence patient enrollment in the RAISE study in October. So far, the company has picked 55 out of the expected 80 clinical sites where it will conduct the trial, and topline data from the study is expected in 1H 2022.

Joe Hulihan, the company’s chief medical officer, stated that in the recent second phase study in RSE, they were able to control status epilepticus at a median time of five minutes after ganaxolone treatment. No patients progressed to IV anesthesia to control seizures within 24 hours. Hulihan said there is an unmet need for RSE treatment, and the company is eager to commence Phase 3, a clinical trial for the indication.
