Clinical Trial Summary

This study aims to investigate the acute effects of cannabinol (CBN) 30 mg and 300 mg, versus placebo, on sleep architecture and next-day functioning in adults aged 25-65 years with chronic insomnia disorder.


Clinical Trial Description

This is a randomised, double-blind, placebo-controlled, three-arm, crossover, single-centre, proof-of-concept study in twenty participants with chronic insomnia disorder (as per clinician diagnosis and Insomnia Severity Index [ISI] Score ≥15). Across three overnight treatment sessions, participants will receive single dose oral liquid 30 mg cannabinol (CBN), 300 mg CBN, and matched placebo. Participants will undergo overnight sleep assessment using in-laboratory polysomnography (PSG) to examine CBN-related changes to sleep parameters; and various objective and subjective measures of sleep and next-day neurobehavioral function. Each treatment session will be separated by the two-week washout period. ;
