Design outcomes

Primary

MeasureTime frame
Change in joint pain and inflammation severity (efficacy of CBD) using WOMAC or equivalent scale. Comparative improvement in pain, stiffness, and function between CBD and placebo groupsTimepoint: To assess the reduction in joint pain and inflammation severity using the WOMAC score and Visual analogue scale from Day 1 (baseline) to Day 90 (End of study). To compare the improvement in pain, stiffness, and function between interventional and placebo groups from Day 1 (baseline) to Day 90 (End of study).

Secondary

MeasureTime frame
The study aims to evaluate the safety and tolerability of CBD through the assessment of adverse events and laboratory parameters. In addition, it will assess the efficacy of CBD on osteoarthritis symptoms by observing changes in the WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score, which measures pain, stiffness, and physical function.Timepoint: Assessments will be conducted at baseline (Week 0) before starting treatment and at the endpoint (Week 12). Optional interim evaluations for safety and laboratory monitoring will also be performed at Weeks 4 and 8.
