We are a clinical-stage biopharmaceutical company dedicated to transforming the treatment of psychiatric and neurological disorders.


Our initial focus is on developing our novel and proprietary 5- Methoxy-N,N-Dimethyltryptamine, or 5-MeO-DMT, therapies for the treatment of patients with Treatment Resistant Depression, or TRD.


Our portfolio currently includes GH001, our proprietary inhalable 5-MeO-DMT product candidate, and GH002, our proprietary injectable 5-MeO-DMT product candidate. Read about our pipeline here


We have completed a Phase 1 healthy volunteer clinical trial, in which administration of GH001 via inhalation was observed to be well tolerated at the investigated single dose levels and in an individualized dosing regimen with intra-subject dose escalation.


GH001 is currently being investigated in the Phase 2 part of an ongoing Phase 1/2 clinical trial in patients with TRD. Based on observed clinical activity, we believe that administration of a single dose of GH001 has the potential to induce ultra-rapid remissions as measured by the Montgomery-Åsberg Depression Rating Scale, or MADRS, in certain patients. The goal of the ongoing Phase 2 part of the trial is to assess whether an individualized dosing regimen with intra-subject dose escalation within a single day can further increase the MADRS remission rate as compared to a single GH001 dose.
