What this trial studies

This randomized, placebo-controlled trial will enroll 30 adults with moderate-to-severe RLS that has not responded to dopaminergic or alpha-2-delta ligand therapies. Participants will be randomly assigned to receive cannabis oil or a matching placebo for eight weeks, with sleep quality and quality of life measured at baseline and at eight-week follow-up. Investigators will monitor for adverse reactions and document feasibility and tolerability of cannabis in this population. The study is being conducted at Sunnybrook Health Sciences Centre and University Health Network in Toronto, Ontario.

Who should consider this trial

Good fit: Adults aged 25 and older with a confirmed RLS diagnosis, symptom onset at least six months earlier, and moderate-to-severe symptoms refractory to dopaminergic or alpha-2-delta ligand therapy are the intended participants.

Not a fit: People with uncontrolled sleep-disordered breathing, recent cannabis use, active substance abuse, pregnancy or breastfeeding, serious cardiac or liver disease, or a history of psychotic disorders may not be eligible and are unlikely to benefit from this treatment.

Why it matters

Potential benefit: If successful, cannabis oil could reduce RLS symptoms and improve sleep and quality of life for patients who have not benefited from standard medications.

How similar studies have performed: There have been no prior randomized clinical trials of cannabis for RLS, though some patients report anecdotal symptom relief.
