In a small clinical trial with 16 adults suffering from treatment-resistant depression, an inhaled form of the psychedelic drug 5-MeO-DMT (GH001) was well tolerated and produced rapid antidepressant effects. An individualized dosing regimen of up to three increasing doses within a single day led to 87.5% of patients achieving remission (a depression score of 10 or less on the MADRS scale) by day 7, compared to 50% and 25% for single doses of 12 mg and 18 mg, respectively. Remission occurred as early as two hours after dosing for some patients. The findings suggest that individualized dosing may be more effective than a single dose.
