Cannabidiol Oral Solution as an Adjunctive Therapy for Treatment of Participants With Inadequately Controlled Dravet Syndrome
A Multicenter, Randomized, Double-blind, Placebo- Controlled, Interventional Study to Assess the Safety and Efficacy of Pharmaceutical Cannabidiol Oral Solution as an Adjunctive Therapy for Treatment of Subjects With Inadequately Controlled Dravet Syndrome
This Phase 3 study will enroll participants diagnosed with Dravet Syndrome (DS) who are still experiencing at least one tonic-clonic, clonic, and/or focal seizures with motor components (FSMC) per week, despite ongoing treatment with up to three antiepileptic drugs (AEDs), and meet the other inclusion/exclusion criteria.
Following a 28-day baseline period, participants will begin an 84-day treatment period. Participants will be assigned to receive twice-daily doses of placebo or cannabidiol oral solution at the highest dose determined to be safe in a previous trial.
Following study completion, all participants will be invited to receive Cannabidiol Oral Solution in an open label extension study (under a separate protocol).

Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Cannabidiol oral løsning
Deltakerne vil motta cannabidiol mikstur i en passende dose (ikke høyere enn 40 mg/kg/dag) bestemt av data fra en tidligere studie.
Den totale daglige dosen vil bli administrert i doser to ganger daglig, med ca. 12 timers mellomrom.
|
An oral solution containing pharmaceutical grade cannabidiol (nonplant-based)
|
|
Placebo komparator: Placebo løsning
Deltakerne vil motta matchende placeboløsning administrert to ganger daglig, med omtrent 12 timers mellomrom.
|
A matching oral solution containing no cannabidiol
