Tests treatment safety and results for Cannabis Withdrawal
Official title Efficacy of PP-01 in Mitigating Cannabis Withdrawal Symptoms in Adults With Cannabis Use Disorder
ClinicalTrials.gov ID: NCT07644052
What this study is testing
What is PP-01?
PP-01 is an investigational medicine, given as an once-daily treatment applied to the skin, being studied as a potential treatment for cannabis withdrawal.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is a randomized, double-blind, placebo and active-controlled, multicenter trial conducted to evaluate whether PP-01 mitigates the withdrawal symptoms associated with discontinuing cannabis in participants with moderate to severe cannabis use disorder (CUD). Study participants will receive PP-01, nabilone, or placebo every day for 34 days.
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
