What this trial studies

This trial aims to evaluate the pharmacokinetics and safety of GH001, a compound containing 5-MeO-DMT, when administered via a proprietary aerosol delivery device to healthy volunteers. Participants will receive a single dose and undergo an individualized dosing regimen to assess the drug's pharmacokinetic profile and its psychoactive effects. The study will also investigate the impact of GH001 on cognitive performance and the time taken for drug concentration to decrease significantly in the body. The trial is designed to ensure participant safety and tolerability throughout the process.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults with a BMI between 18.5 and 35 kg/m2 and good mental health.

Not a fit: Patients with known allergies to mebufotenin or related compounds, or those with significant health conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the safe administration and effects of GH001, potentially paving the way for therapeutic applications.

How similar studies have performed: While the specific approach of using an aerosol device for GH001 is novel, similar studies on psychoactive compounds have shown varying degrees of success.

Inclusion Criteria:

* Body mass index (BMI) in the range of 18.5 to 35 kg/m2 (inclusive) at screening
* Good mental health in the opinion of the investigator.
* Normal spirometry (FEV1 of \>80% of predicted and FVC of \>80% of predicted value) at screening.

Exclusion Criteria:

* Has known allergies or hypersensitivity or any other contraindication to mebufotenin, bufotenin, melatonin or triptans.
* Has received any investigational medication, including investigational vaccines, in the 3 months prior to baseline or is in the follow-up period of another clinical trial at the time of screening for this trial.
* Has a current or past clinically significant condition, which renders the subject unsuitable for the trial according to the investigator's judgement.
