NRx said the FDA issued a positive review letter on its preservative-free ketamine ANDA, requesting only minor administrative changes. The company also received FDA guidance outlining a path to an NDA for NRX-100 using clinical trial data and real-world evidence.
NRx Pharmaceuticals said an FDA Type C meeting indicated a path to an NDA for NRX-100, using clinical trial results and real-world ketamine data from more than 65,000 patients.
NRx said the FDA outlined a path for a New Drug Application for NRX-100, a preservative-free ketamine formulation for depression with suicidality. The company plans to submit the NDA by June 2026 and said no additional nonclinical or bridging studies would be required.
