The big picture
This FDA guidance represents a significant validation of ketamine's potential in depression treatment, particularly for severe cases with suicidality. The acceptance of real-world evidence alongside clinical trials suggests growing regulatory flexibility for mental health treatments. NRx's ability to avoid additional trials could position it as a first-mover in this expanded indication space, though commercial success will depend on execution against the June 2026 NDA target.
