CBD for Knee Osteoarthritis

Study Purpose

Osteoarthritis is a disease that affects millions of Americans and is the leading cause of persistent pain and physical disability in the older adult population. Many physically active Americans have reported pain-relieving effects of cannabidiol (CBD) that can reduce or eliminate use of nonsteroidal anti-inflammatory drugs (NSAIDs) for activity-related pain with minimal to no side effects. Long-term use of over-the-counter medications, including NSAIDs, can pose a significant health risk, and therefore clinical research on the safety and efficacy of CBD is needed.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT06414473
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Knee OA is the most common joint disease and a major cause of functional limitation and pain in adults. Pain is the primary symptom of OA, and the main reason people seek medical treatment. Although pharmacologic treatment for OA such as opioid-based medications may help in the short-term with reducing pain-related symptoms, they are known to have mild to severe side effects along with the potential for long-term dependency. Consequently, many Americans have turned to cannabis-related products like cannabidiol or CBD for reducing pain and pain-related symptoms associated with OA. Current research has shown evidence that phyto-cannabinoids may have a promising therapeutic potential in a variety of physical and psychological ailments, and cannabidiol (CBD) is of particular interest due to its positive safety profile, non-intoxicating effects, and purported therapeutic capabilities in several musculoskeletal diseases. In vitro and in vivo studies have shown that CBD administration in the short term is safe and effective in reducing inflammation and pain behaviors in animal models of OA. Despite the widespread popularity of CBD in the US, there is very limited data that indicates the safety, acceptability, and pain-relieving effects of CBD use for people with symptomatic knee osteoarthritis. The investigators' objective will be to conduct an early-stage clinical trial to investigate the safety, tolerability/acceptability, and efficacy of CBD as a non-pharmacological treatment for symptomatic knee OA. The investigators will conduct an innovative and novel study with rigorous scientific design that will assess and monitor symptomatic relief and improved function following CBD administration (active) or placebo-control using a randomized, double-blind, placebo-controlled, cross-over study design. The investigators will be recruiting 30 adult men and women, between 40 and 75 years of age, with an established clinical diagnosis of knee OA. To be included in the study, participants must report having moderate to severe knee pain (≥4/10) with physical activity in one or both knees. Subjects will be required to complete a 78-day study trial spanning a pre-dosing screening visit, baseline testing, 30-day dosing regimen with follow-up testing. A 2-week wash-out period will be followed by the cross-over phase using identical baseline and follow-up testing procedures. The data from the active CBD phase will be compared to data from the placebo-control phase. There is an extremely large consumer base for CBD-related products in the US, and this base will be expanding exponentially over the course of this decade; therefore, scientific investigation into its therapeutic potential is necessary.
