  4. Slide 4: Background: TRD and GH001

    TRD remains one of the most pressing challenges in psychiatry affecting approximately 30% of patients treated for MDD1 Current therapies for TRD are limited, and there is a large unmet need for treatments that are well tolerated and offer rapid therapeutic benefit and long-term remission Mebufotenin

  5. Slide 5: Trial Schematic and Re-treatment Criteria

    For re-treatment (up to five GH001 IDRsa), the patient must have met one of the following criteria: MADRS score >18 MADRS score >10 and ≤18 and MADRS score ≤10 not observed at Day 8 of the prior treatment or at any visit since MADRS score >10 and ≤18 and MADRS score >18 observed since the most recen
