* Eligibility criteria for age was 2-55 years. 32% of patients in LGS studies were ages 18-55. Both trials had a 4-week baseline period, during which patients were required to have a minimum of 8 drop seizures while on stable ASM therapy.1-2

* In the Dravet syndrome study, eligibility criteria for age was 2-18 years. During the 4-week baseline period, patients were required to have at least 4 convulsive seizures while on stable ASM therapy.

* Eligibility criteria for age was 1-65 years. During the 4-week baseline period, patients were required to have a minimum of 8 TSC-associated seizures (countable focal or generalized), with at least 1 seizure per week in ≥3 of the 4 weeks while on stable ASM therapy.5

* Eligibility criteria for age was 2-55 years. 32% of patients in LGS studies were ages 18-55. Both trials had a 4-week baseline period, during which patients were required to have a minimum of 8 drop seizures while on stable ASM therapy.1-2

‡ Eligibility criteria for age was 1-65 years. During the 4-week baseline period, patients were required to have a minimum of 8 TSC-associated seizures (countable focal or generalized), with at least 1 seizure per week in ≥3 of the 4 weeks while on stable ASM therapy.5

EPIDIOLEX delivers broad-spectrum efficacy to significantly reduce generalized (LGS, Dravet syndrome, and TSC) and focal (TSC) seizures

EPIDIOLEX was studied in 900 patients, the largest clinical trial program to date in LGS, Dravet syndrome, and TSC∥‡

4 RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, MULTICENTER PHASE 3 TRIALS1-4
