Abstract Details

Seizure Outcomes With Cannabidiol (CBD) in Pediatric Versus Adult Patients With Lennox-Gastaut Syndrome (LGS) and Dravet Syndrome (DS): Subgroup Analysis of BECOME, a Caregiver Survey
Epilepsy/Clinical Neurophysiology (EEG)
P14 - Poster Session 14 (11:45 AM-12:45 PM)
9-006

A substantial proportion of caregivers reported improvements in seizure and nonseizure outcomes in the primary analysis of the survey.

To characterize and quantify seizure-related outcomes in pediatric (<18 years) versus adult (≥18 years) patients from the cross-sectional caregiver survey BECOME (BEhavior, COgnition, and More with Epidiolex®).

The US-based caregivers (N=498) of patients with LGS (80%) or DS (20%) who received ≥3 months of CBD treatment (Epidiolex®, 100 mg/mL oral solution) compared the past month with the period before CBD initiation. The online survey included multiple-choice and rank-order questions; changes were rated using a symmetrical 5- and 7-point Likert scale (from worsening to improvement).

Mean (standard deviation) patient age: 16 (11) years; median (IQR) CBD dose: 14 mg/kg/d (8–19 mg/kg/d); median concomitant ASMs: 4. Most caregivers of pediatric (n=315) and adult (n=183) patients reported any improvement (possible, definite minor, or definite major) in seizure frequency (84% each) and severity (77% and 75%). Worsening in seizure frequency was reported by 7% and 5% of caregivers of pediatric and adult patients, respectively; 10% and 6% reported any worsening in seizure severity. Caregivers of pediatric and adult patients reported any decrease in the frequency of specific seizure type as follows: convulsive (72% each), drop (71% each), nonconvulsive/nondrop (66% and 69%), and night-time seizures (61% and 63%). Similar proportions of caregivers of pediatric and adult patients reported improvements in seizure-free days/week for ≥1 seizure type (65% and 70%) and seizure freedom in the past month (18% and 15%). Many respondents in both groups reported reductions in rescue medication use (57% each), emergency room visits (56% and 51%), hospitalizations (55% and 50%), and occurrence of seizure-related injuries (48% and 49%).

A substantial proportion of caregivers of patients with LGS or DS, regardless of age, reported improvements in seizure-related outcomes with CBD treatment.
