RADNOR, Pa., June 22, 2016 (GLOBE NEWSWIRE) -- Marinus Pharmaceuticals, Inc. (Nasdaq:MRNS), a biopharmaceutical company dedicated to the development of innovative therapeutics to treat epilepsy and neuropsychiatric disorders, today announced that it has dosed the first subject in its Phase 1 clinical trial of ganaxolone IV, an intravenous (IV) formulation of Marinus' CNS-selective GABAA modulator, for the treatment of status epilepticus (SE). The study is designed to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of ganaxolone IV in healthy volunteers, with data anticipated in the second half of 2016.
Albena Patroneva, M.D., chief medical officer of Marinus Pharmaceuticals, commented, "Status epilepticus is a life-threatening medical emergency associated with high mortality and limited treatments. Typically, single or combination IV antiepileptic drugs are used in an attempt to break the seizures, however there are approximately 45,000 patients in the U.S. who do not respond to treatment and progress to established SE. Our preclinical research suggests ganaxolone IV could be a promising therapeutic in this difficult to treat seizure disorder, especially after first-line benzodiazepine treatment fails to halt the seizures. We look forward to reporting the results on this Phase 1 study later this year."
Christopher M. Cashman, chief executive officer of Marinus Pharmaceuticals, added, "Dosing the first subject with ganaxolone IV in SE is an important event for Marinus as we focus the development of ganaxolone on target patient populations where we believe there to be a strong mechanistic rationale for a therapeutic benefit with ganaxolone. Strategically, we believe that ganaxolone IV in combination with our convenient oral capsule and liquid formulations, has the potential to provide continuity of care for patients suffering from drug-resistant seizures in both acute and chronic care settings."
The Phase 1 study, which will be conducted at Duke University Medical Center, will include a dose escalation of a bolus dosage of ganaxolone IV and a bolus dose of ganaxolone IV, followed by a continuous infusion. The primary study objective is to evaluate the safety and PK of ganaxolone IV. The secondary study objectives include the PD effects of ganaxolone IV on electroencephalogram (EEG) parameters and ventilation, as well as the effect of ganaxolone IV on clinical sedation scores.
Marinus recently received Orphan Drug Designation for ganaxolone IV, providing the company with several benefits that could potentially shorten the timeline and reduce the costs of development.
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 in a Phase 1 clinical trial 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 and liquid are being studied in orphan pediatric indications with comorbidities in seizures and behavior disorders — PCDH19 epilepsy and Fragile X Syndrome.
