A Randomized, Double Blind, Placebo-controlled Parallel Study of Tolerability and Efficacy of Cannabidiol (CBD) on Motor Symptoms in Parkinson's Disease

ClinicalTrials.gov · COMPLETED, 2022

74 participants

Abstract

The major purpose of this study is to assess the efficacy of CBD on motor symptoms of Parkinson's Disease (PD), and secondarily to study the safety and tolerability of CBD and other efficacy, particularly regarding tremor in PD. The study has been powered to detect a clinically significant reduction in Movement Disorder Society (MDS) Unified Parkinson's Disease Rating Scale (UPDRS) Part III motor scores. This is a 1:1 parallel, double-blind, randomized controlled trial (RCT) with 60 participants. The investigators will be recruiting up to 75 participants; the goal is to have 60 participants (30 in CBD group and 30 in placebo group) complete the study. The study drug is obtained from the National Institute on Drug Abuse (NIDA).

Conditions: Parkinson Disease.

Primary outcome: Change in Movement Disorders Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III (Motor Examination) Scores.

Enrollment: 74 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 74 participants or records.
