What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Psilocybin 5 mg, Psilocybin 25 mg, or Motivational Support. The registry lists allocation as randomized. The goal of this clinical trial is to learn whether it is possible to use psilocybin in combination with motivational support therapy to treat moderate-to-severe methamphetamine use disorder (MeUD) in people with HIV who are seeking to stop using methamphetamine.
They plan to enroll about 30 people at San Francisco. Taking part typically means taking a study drug (or dummy pill), following a program (exercise, therapy, diet, or an app) plus check-ins.
