NeuroRx, Inc. announced that it has received a notice of patent allowance covering the Composition of Matter for its drug NRX-101, which targets suicidal bipolar depression, an unmet medical need that results in the death of more than 25,000 Americans each year. The allowance is based on US Patent Application 15/987,932 entitled: Composition and Method for Treatment of Depression and Psychosis in Humans. The inventor, Prof. Daniel Javitt, Ph.D., M.D., is co-founder of NeuroRx and was among the first to report the role of the NMDA receptor in psychiatric disease. NRX-101, an NMDA-targeted antidepressant, is a fixed-dose combination of D-cycloserine and lurasidone and was awarded Fast Track and Breakthrough Therapy Designation by the US FDA. The drug is currently undergoing phase 3 clinical trials under an FDA Special Protocol Agreement.
