Trial Summary

What is the purpose of this trial?This single-site study is a pilot, three-armed, double-blinded, placebo-controlled randomized controlled trial (RCT) that will determine the feasibility of a definitive RCT investigating the use of cannabis oil as a treatment for insomnia in individuals with MDD. The study will also determine whether standard THC with higher CBD vs lower CBD has a differential impact on insomnia. The study will also analyze other important objective parameters of sleep including total sleep time and sleep efficiency from actigraphy data. Optional polysomnography data may also be collected and analyzed. In addition, standardized, validated instruments will be used to collect data on severity of depressive symptoms, cognitive functioning biological rhythm disruption, daytime sleepiness, health-related quality of life (HRQoL), healthcare resource utilization, work productivity and activity impairment, as well as other side effects, in order to better understand the potential impact of the use of cannabis oil on these important health outcomes.

Participant Groups

This study tests the effectiveness of two different ratios of CBD/THC (25:1 and 5:1) against a placebo in treating insomnia among those with major depressive disorder. It's a pilot trial to see if a larger one would work. The trial will also measure sleep quality and other health outcomes like depression severity and cognitive function.
