Brief summary

This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy, safety and tolerability of CBD capsules in adults with sleep disturbance. Adults will be screened for study eligibility by attending the clinic between Day -28 and Day -4. Study eligibility will be confirmed at the clinic on Day -3 and baseline measures will be conducted at home between Days -3 to Day 1 with Day 1 being the first day of study drug administration. Participants will be required to attend the study clinic at screening, on Day 31, and Day 37 (EOS) or ETV. There will be no clinical confinement period in this study and all clinical assessments will be performed as outpatient visits or telehealth consultations. The study will evaluate 3 dose levels of the investigational product, Satipharm CBD capsules or placebo in 4 parallel treatment arms of 53 participants per arm. Participants will be enrolled across 4 parallel treatment arms to receive daily doses of Satipharm CBD or placebo for a period of 30 days. Treatment Arm 1 : 0mg (placebo), Treatment Arm 2: 25 mg, treatment arm 3: 50 mg, treatment arm 4:100 mg. A single daily dose of Satipharm CBD capsules or placebo (2 capsules/dose) will be administered from Day 1 to Day 30 whereby each participant will receive a total of 30 doses with an evening meal. Study drug will be self-administered on a daily basis from Day 1 through to Day 30. Outpatient clinic visits are scheduled for Days 31 (the day following the last dose of study drug), and again on Day 37 which is the end of study (EOS) visit.
