RADNOR, Pa., January 19, 2023 /PRNewswire/ NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) (“NRx Pharmaceuticals”, the “Company”), a clinical-stage central nervous system (CNS) biopharmaceutical company, today announced that it had a meeting and a written response from the Food and Drug Administration (FDA) last week regarding its lead compound, NRX-101. 

In response to a request for Type C guidance on the chemistry, manufacturing and controls (CMC) aspects of the NRX-101 program, FDA provided Written Responses on January 10th.  As previously announced in October 2022, an updated NRX-101 module 3 was submitted to add the intended commercial manufacturer to the IND. With FDA’s written response, it appears that NRx Pharmaceuticals has reached alignment with the FDA regarding its proposed registration manufacturing plan.  

A Type B meeting with the FDA was held on January 11, 2023.   

Minutes of the meeting are expected to be available in approximately 30 days.   

“We appreciate the FDA’s ongoing guidance and support under the Breakthrough Therapy Designation associated with NRX-101 as well the previously issued Special Protocol Agreement for the treatment of Bipolar Depression in Patients with Acute Suicidal Ideation and Behavior.  Our quest is to develop the first medicine to treat patients with suicidal depression and aim to develop a new drug therapy for post-traumatic stress disorder (PTSD)”, said Stephen Willard, chief executive officer of NRx Pharmaceuticals.  “We look forward to continued discussions addressing our mutual goal to treat bipolar depression and suicidality at a time when someone in the United States attempts suicide every 27 seconds.” 


About NRx Pharmaceuticals 

Clinical-stage biopharmaceutical company developing therapeutics for the treatment of central nervous system disorders, specifically suicidal depression and post-traumatic stress disorder (PTSD). The company’s lead program NRX-101, an oral, fixed-dose combination of D-cycloserine and lurasidone, targets the brain’s NMDA receptor and is being investigated in a Phase 3 trial under an FDA Special Protocol Agreement and Breakthrough Therapy Designation in patients with bipolar depression and suicidal ideation, an indication for which the only approved treatment is electroshock therapy. NRx Pharmaceuticals has also initiated a Phase 2b clinical trial in patients with Sub-Acute Suicidality, a substantially broader indication.
