BusinessUpdates

GH001inPatientswith TRD

GH001, our proprietary inhaled mebufotenin (5-MeO-DMT) product candidate, is currently being investigated in a multi-center, randomized, double-blind, placebo-controlled Phase 2b trial in approximately 80 patients with treatment-resistant depression (TRD) (GH001-TRD-201). GH001 is administered on a single dosing day, without mandated in-trial psychotherapeutic intervention, consistent with our previously completed trials.

We completed enrolment of the double-blind phase in the third quarter of 2024, with top-line data expected to be available in the fourth quarter of 2024 or the first quarter of 2025. This trial includes a 6-month open-label extension which is on track for completion in the first quarter of 2025.

GH001AdministeredwithProprietaryAerosolDeliveryDevice

Our Phase 1 clinical pharmacology trial to evaluate our proprietary aerosol delivery device for administration of GH001 in healthy volunteers (GH001-HV-106) is ongoing in the United Kingdom. This trial is designed to support our global program for GH001, by bridging to the clinical data generated with the commercially available device that we have used in our clinical trials to date.

UpdateonINDforGH001

As previously announced, our investigational new drug application (IND) for GH001 administered using our proprietary aerosol delivery device was placed on clinical hold by the U.S. Food and Drug Administration (FDA). Based on interactions with the FDA, we believe we have a path to respond on the device element of the hold. The nonclinical studies to address the inhalation toxicology aspect are ongoing.

Proof-of-Concept Trials with GH001

GH001 is being investigated in a proof-of-concept clinical trial in bipolar II disorder in patients with a current depressive episode (BDII) (GH001-BD-202). While increasing the number of sites has improved enrolment, recruitment has continued to be difficult and, for these reasons, the trial will end in the fourth quarter of 2024.

GH001 is also being investigated in a proof-of-concept clinical trial in patients with postpartum depression (PPD) (GH001-PPD-203). We continue to expect GH001-PPD-203 completion in the fourth quarter of 2024.

AboutGH001

Our lead product candidate, GH001, is formulated for mebufotenin (5-MeO-DMT) administration via a proprietary inhalation approach. With GH001, we have completed two Phase 1 healthy volunteer clinical trials and a Phase 1/2 clinical trial in patients with TRD. Based on the observed clinical activity, where 87.5% of patients with TRD achieved ultra-rapid remission with our GH001 individualized single-day dosing regimen in the Phase 2 part of the trial, we believe that GH001 has the potential to change the way TRD is treated today.

AboutGH002andGH003

GH002 is our mebufotenin (5-MeO-DMT) product candidate formulated for administration via a proprietary intravenous approach. We have completed a Phase 1 trial of GH002 in healthy volunteers. GH003 is our mebufotenin (5-MeO-DMT) product candidate formulated for administration via a proprietary intranasal administration approach. GH003 is currently in preclinical development. We anticipate developing GH002 and GH003 within our focus areas of psychiatric and neurological disorders.
