Trial and study design: Post hoc analyses of data from two randomized, placebo-controlled, Phase 3 trials

Sample size: N= 235,

Dosage and duration: Highly purified CBD (100 mg/ml oral solution) at 10 mg/kg/day or 20 mg/kg/day or placebo for 14 weeks

Results:

  • Treatment effect (efficacy and AEs) of CBD may occur within 1 week of starting treatment. Although AEs lasted longer for CBD than placebo, most resolved within the 14-week period.

Safety and side effects:

  • Onset of the first reported AE occurred during the titration period in 45% of patients (CBD10, 46%; CBD20, 52%; placebo, 38%). In patients with AEs, resolution occurred within 4 weeks of onset in 53% of placebo and 39% of CBD patients and by end of study in 63% of placebo and 61% of CBD patients.
