- In vivo study of M2 metabolite shows no signs of genotoxicity
- Marinus’ CDKL5 deficiency disorder marketing authorization application to convert to standard review timeline
RADNOR, Pa.--(BUSINESS WIRE)-- Marinus Pharmaceuticals, Inc. (Nasdaq: MRNS), a pharmaceutical company dedicated to the development of innovative therapeutics to treat seizure disorders, today announced preliminary results from an in vivo study on the M2 metabolite showing that no genotoxicity was found, as measured by formation of micronuclei in the bone marrow or comet morphology in the liver.
In August 2021, Marinus announced a collaboration with Orion Corporation for European commercialization of ganaxolone. Under the agreement, Orion paid Marinus €25 million (~$30 million at the time of announcement) in cash as an upfront fee, subject to a 75% clawback of the upfront payment and a right to terminate the agreement in the event the M2 metabolite study showed genotoxicity. The final study report is expected prior to the end of February 2022.
Marinus also announced its marketing authorization application (MAA) for ganaxolone in CDKL5 deficiency disorder will convert to a standard review and that it had reached an agreement with the European Medicines Agency (EMA) to extend the Day 120 clock stop by three months to allow sufficient time to respond to questions received as part of the review process. The company now expects the EMA’s Committee for Medicinal Products for Human Use opinion on the MAA by year end 2022.
