Phase 3 Study of LP352 Versus Placebo for Treating Seizures in Children and Adults With Dravet Syndrome

What this Trial Is About

Researchers are evaluating the drug LP352 in a phase 3, randomized, double-blind, placebo-controlled trial to study its effects on seizures in children and adults with Dravet Syndrome DS. This serious condition involves various seizure types with onset between 1 and 20 months of age. The study aims to test the efficacy, safety, and tolerability of LP352 compared to placebo over a total duration of about 24 months. Participants will be randomly assigned to receive either LP352 or a matching placebo. LP352 or placebo will be given orally or through a feeding tube. The study includes three main phases a Screening phase, a Titration period where doses are gradually increased to the highest tolerated level, and a Maintenance period to assess ongoing treatment effects. Afterward, participants will undergo a Taper period to reduce dosing and a Follow-Up phase for observation. During the study, participants will be monitored for seizure frequency changes, safety, and tolerability. Researchers will track countable motor seizures and measure percent change compared to baseline over up to 15 weeks. Participants or caregivers will complete seizure diaries, and stable antiseizure medication use is required. Safety evaluations will continue up to 21 weeks, with study visits scheduled throughout these phases. Total participation lasts approximately two years.
