The SPARC-TMS trial will begin enrolling patients at McLean Hospital, Arizona State University and HOPE Therapeutics, with leading military hospitals joining as affiliates. The program aims to replicate prior real-world outcomes of 91% response and 69% remission at three months using TMS with d-cycloserine. NRx Defense expects the study could support an FDA registration package for NRX-101 used alongside TMS in treatment-resistant depression.
