Epidiolex Trial for Presymptomatic Treatment of Sturge-Weber Syndrome
brief summary
Patients with Sturge-Weber syndrome (SWS) are frequently affected by seizures, and seizures are associated with poorer neurological outcomes. To date there is no established means of predicting or preventing seizure onset. Cannabidiol (Epidiolex) was well tolerated in an open label study in this population. This trial will evaluate whether Epidiolex in presymptomatic Sturge-Weber patients may delay the onset of seizures and improve neurological outcome.
detailed description
This is an open-label, prospective dose escalation study to determine the safety and tolerability of presymptomatic treatment of SWS patients with Epidiolex. The investigators hypothesize that Epidiolex will be well tolerated and delay seizure onset in SWS patients. The total number of subjects to be consented for this safety study=10 babies with SWS; the initial funded phase will be with 6 subjects. Interim analysis will be completed after 6 subjects; the remaining 4 will be enrolled as warranted for 6 months on Epidiolex. Subjects will be dosed as recommended clinically (starting at 2.5 mg/kg/day divided bid, with weekly increases over the next 4 weeks to a maximum dose of 20 mg/kg/day) as tolerated. Neurologic visits during the trial, the bloodwork, EEGs, and motor assessments will be done as research procedures. Once the first dose of the study drug is administered, a blood draw will be done at 4-hour and 12-hour post study drug administration. A mini-PK will be similarly performed once the maximum maintenance dose is achieved.
