This (DEEp SEA Study) is a double-blind, randomized, placebo-controlled, multicenter study to investigate the efficacy, safety, and tolerability of LP352 in the treatment of seizures in children and adults with DS. The study consists of 3 main phases: Screening, Titration period, and Maintenance period, followed by a Taper period and Follow-Up. Participants will be randomized to LP352 or placebo. The total duration of the study will be approximately 24 months.
ENDEAVOR is a Phase 1/2, 2-part, multicenter study to evaluate the safety and efficacy of ETX101 in participants with SCN1A-positive Dravet syndrome aged ≥6 to \<36 months (Part 1) and aged ≥6 to \<48 months (Part 2). Part 1 follows an open-label, dose-escalation design, and Part 2 is a randomized, double-blind, sham delayed-treatment control, dose-selection study.
The primary purpose of this study is to evaluate the safety, tolerability, and efficacy of ZX008 (fenfluramine hydrochloride) when added to adjunctive antiepileptic stiripentol treatment in children and young adults with Dravet syndrome.
Study 1 and Study 3 are the prospective, merged analyses of 2 identical double-blind, placebo-controlled studies, ZX008-1501 and ZX008-1502, to assess the efficacy, safety, and pharmacokinetics of ZX008 when used as adjunctive therapy in pediatric and young adult subjects with Dravet syndrome. Study 1501 and Study 1502 were conducted in parallel; Study 1501 was conducted at approximately 30 study sites in North America; Study 1502 was conducted at approximately 30 study sites in Europe, Asia and Australia. Upon completion of the Baseline Period after initial Screening and Baseline charting of seizure frequency, subjects who qualified for the studies were randomized (1:1:1) in a double-blind manner to receive either 1 of 2 doses of ZX008 (0.2 mg/kg/day or 0.8 mg/kg/day; maximum dose: 30 mg/day) or placebo. Randomization was stratified by age group (\< 6 years, ≥6 to 18 years) to achieve balance across treatment arms, with the target of 25% of subjects in each age group. All subjects were titrated to their randomized dose over a 14-day Titration Period. Following titration, subjects continued treatment at their randomly assigned dose over a 12-week Maintenance Period. Subjects exiting the study underwent a 2-week taper, unless they enrolled in a follow-on study. Subjects were followed for post-study safety monitoring.
The purpose of the study is to evaluate the efficacy, safety, and tolerability of zorevunersen in Patients with Dravet syndrome.

This is an expanded access use of Stiripentol in Dravet Syndrome or epileptic encephalopathies associated with sodium channel mutations who have failed other drugs in an effort to give them the best chance at seizure control and quality of life. As a treatment protocol and not a research study, children will only be monitored on a clinical basis for seizure improvement and side effects predominantly by parent and caregiver report.
Dravet syndrome is a genetic epilepsy associated with pathogenic variants in SCN1A that codes for Nav1.1, a protein necessary for sodium channels. Children with Dravet syndrome classically present in the first year of life with prolonged seizures, often hemiclonic and in the setting of fever or temperature changes such as getting in or out of bath water. Many anti-seizure medications are sodium channel blockers and exacerbate seizures in this patient population. This creates some limitations in medication choices for this patient population. Recently fenfluramine was approved for use in Dravet syndrome for people 2 years and older. Randomized studies demonstrated a 74.9% reduction of convulsive motor seizures compared to 19.2% in the placebo group. Additionally, 16% of children treated with fenfluramine were seizure free. Fenfluramine is likely to be as effective in children under the age of 2 years. The current study has proposed a treatment protocol to allow access to fenfluramine for children under 24 months of age.
The primary purpose of this study is evaluate the safety and tolerability of fenfluramine hydrochloride (HCl) 0.2 to 0.8 mg/kg/day in infants 1 year to less than 2 years of age with Dravet syndrome.
This is a multicenter, double-blind, parallel-group, placebo controlled, 2-part study to evaluate the efficacy and safety of ZX008 when used as adjunctive therapy for the treatment of uncontrolled seizures in children and adults with cyclin-dependent kinase like-5 (CDKL5) deficiency disorder (CDD).
The primary purpose of the study is to demonstrate that lorcaserin has superior efficacy compared to placebo on percent change in frequency of convulsive seizures per 28 days in participants with Dravet syndrome.
Owing to the recent classification of CDKL5 Deficiency Disorder (CDD) as a unique disorder, there is a limited understanding of overall disease natural history and meaningful outcome measures. An international patient registry aimed at collecting both patient/caregiver and clinician-entered demographic, patient-reported outcome (PRO) and treatment data would benefit both the scientific and patient communities. This CDD registry will follow up to 500 patients diagnosed with CDD over several years through both the patients/caregivers and their clinicians. Initial data will be collected upon enrollment in the registry, followed by the collection of additional CDD-specific data on a bi-annual/ annual basis. No procedures will be performed as part of this registry. Clinician-entered data will be collected following standard of care visits conducted as part of patients' ongoing clinical care. Ultimately, the goal is to create a contact registry to allow patients/families to be alerted about relevant clinical trials and to collect valuable information that is accessible to the patient and scientific communities, thereby aiding and encouraging research in CDD.
This is a multicenter, Phase 3, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of clemizole HCL (EPX-100) as adjunctive therapy in children and adult participants with Dravet syndrome.
The primary purpose of this study is to provide continued access of lorcaserin to participants with Dravet syndrome and other refractory epilepsies.
The purpose of this study is to investigate the effect of soticlestat on the frequency of motor seizures for participants with Dup15q or CDD during the Maintenance Period.
This is a phase 2, crossover study of Ataluren for the treatment of nonsense mutation Dravet syndrome or cyclin-dependent kinase-like 5 (CDKL5) deficiency, resulting in drug-resistant epilepsy. Patients will receive 12 weeks of ataluren or placebo during each treatment period. Treatment Period 1 will be followed by a 4-week Washout Period. Based on ataluren PK and pharmacodynamic data, the 4-week washout period is deemed an appropriate length of time to eliminate any ataluren drug effects. Following the Washout Period, patients will crossover to receive the opposite treatment during Treatment Period 2 as follows: Patients receiving ataluren during Treatment Period 1 will receive placebo during Treatment Period 2. Patients receiving placebo during Treatment Period 1 will receive ataluren during Treatment Period 2.

This study will non-invasively obtain levels of GABA in the brain of children with SCN1A+DS and neurodeveloping children through evoked and induced cortical responses, correlate them with the BOLD responses, and with the levels of GABA in their blood.
Pathogenic variants in the Cyclin-dependent kinase like 5 (CDKL5) gene cause CDKL5 deficiency disorder (CDD, MIM 300672, 105830), a severe developmental and epileptic encephalopathy associated with cognitive and motor impairments and cortical visual impairment. While capability for disease modifying therapies is accelerating, there is a critical barrier for clinical trial readiness that may result in failure of these therapies, not due to lack of efficacy but due to lack of validated outcome measures and biomarkers. The measures and biomarkers validated here will be adaptable to other developmental and epileptic encephalopathies.
Observational, noninterventional, 3-year study to examine the presence of detectable differences in neurocognitive, developmental, motor, neurophysiologic, and quality of life measures over time in patients with cyclin-dependent kinase-like 5 deficiency disorder.
The main aim of the study is to learn if soticlestat, when given as an add-on therapy, reduces the number of seizures in children and adults with Dravet Syndrome (DS) or Lennox-Gastaut Syndrome (LGS). Participants will receive their standard anti-seizure therapy, plus tablets of soticlestat. There will be scheduled visits and follow-up phone calls throughout the study.
The main aim of the study is to learn if soticlestat, when given as an add-on therapy, reduces the number of convulsive seizures in children and young adults with DS. Participants will receive their standard antiseizure therapy, plus either a tablet of soticlestat or placebo for 16 weeks. A placebo looks just like soticlestat but will not have any medicine in it. Participants may continue treatment in an extension study, based on the extension study's entry criteria. Those that want to stop treatment will have a gradual dose reduction during 1 week and then be followed up for 2 weeks.
