This unregistered trial (n=59) was an evaluator-blind, randomised controlled trial of multiple versus single ketamine-assisted psychotherapy sessions for heroin dependence in detoxified adults, which found that repeated sessions significantly improved long-term abstinence rates.

Detailed Description

This synthetic trial has been added to our database because a psychedelic paper (about a clinical trial) references this trial, but no (live) registration can be found.

The study investigated whether repeated sessions of ketamine-assisted psychotherapy (KPT) provided greater benefits for heroin abstinence compared to a single session. Following inpatient detoxification, 59 participants were randomised to receive either three ketamine sessions (2.0 mg/kg IM) spaced one month apart with psychotherapy, or a single ketamine session followed by monthly addiction counselling.

At the twelve-month follow-up, survival analysis indicated that the multiple KPT group achieved a significantly higher rate of abstinence (50%) compared to the single KPT group (22.2%). While abstinence rates were improved, no significant differences were observed between the groups regarding depression, anxiety, heroin craving, or sense of purpose in life.
