Time to onset of cannabidiol treatment effects in Dravet syndrome: Analysis from two randomized controlled trials.

ABSTRACT:

Objective

We conducted a post hoc analysis of two randomized controlled trials, GWPCARE1 (NCT02091375) and GWPCARE2 (NCT02224703), to estimate the time to onset of cannabidiol (CBD) treatment effects (seizure reduction and adverse events [AEs]) in patients with Dravet syndrome (DS).

Methods

Patients received either plant-derived highly purified CBD (Epidiolex in the United States; 100 mg/ml oral solution) 10 mg/kg/day (CBD10; GWPCARE2) or 20 mg/kg/day (CBD20; GWPCARE1&2), or matching placebo for 14 weeks. Treatment started at 2.5 mg/kg/day, reached 10 mg/kg/day on Day 7, and went up to 20 mg/kg/day on Day 11 during the 14-day titration period. Percentage change from baseline in convulsive seizure frequency was calculated by cumulative day (i.e., including all previous days).
