RecruitingPhase 3Combination productEfficacy of PP-01 in Mitigating Cannabis Withdrawal Symptoms in Adults With Cannabis Use DisorderThis 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. The total study duration will be approximately 78 days, including screening and a one-week inpatient stay. Following the initial inpatient portion of the study, participants will return to the clinic for six clinic visits and complete two telemedicine appointments. Participants will complete daily symptom diaries and other study-related questionnaires. Participants who complete the core study may be eligible to participate in a repeat dosing extension study if they meet required criteria.
