Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a clinical trial of a high-cannabidiol (CBD) sublingual product compared to placebo for 9 weeks in patients with chronic pain conditions. The study will assess the impact of CBD on chronic pain symptoms, conventional medication use, clinical state, quality of life, cognition, and biomarkers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cannabis sativa has been used medicinally to treat a wide range of disorders for thousands of years. Cannabis is comprised of more than 100 cannabinoids, including D9-tetrahydrocannabinol (THC), the major intoxicating constituent, and cannabidiol (CBD), the major non-intoxicating constituent that has a number of potential therapeutic properties. Although a wide range of medical cannabis (MC) and hemp products (containing less than 0.3% THC) are used by consumers for a variety of medical indications, little is known about the direct impact of individual cannabinoids and constituent ratios on the symptoms that cause patients to seek treatment.

Chronic pain is one of the most common indications for MC use, and several studies have yielded compelling data suggesting that MC and its constituents may have analgesic and anti-inflammatory properties, suggesting that cannabinoids may have the potential to treat chronic pain. This investigation will involve a placebo-controlled crossover trial of a hemp-derived high-CBD, low-THC sublingual product in patients with chronic pain; patients will be assessed at baseline and over 69weeks of treatment with CBD or placebo on measures of clinical state, including pain and related symptoms, conventional medication use, and cognition, and provide samples for analysis of inflammatory markers.
