About NRx Pharmaceuticals
NRx Pharmaceuticals is a 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 a Food and Drug Administration (“FDA”) Special Protocol Agreement and Breakthrough Therapy Designation in patients with bipolar depression and acute 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, potentially a substantially broader indication. The Breakthrough Therapy Designation and Special Protocol Agreement were awarded by the FDA based on the Company’s prior STABIL-B trial that demonstrated substantial improvement over available therapy in reducing depression and suicidality compared to placebo when patients were treated with NRX-101 after a single dose of ketamine.
