Filter by:EXPEDITION is a Phase 1/2 study in the UK to evaluate the safety and efficacy of ETX101 in participants with SCN1A-positive Dravet Syndrome aged 6 to < 48 months. The study follows and open-label, dose-escalation design.
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.
WAYFINDER is a Phase 1/2 study in Australia to evaluate the safety and efficacy of ETX101 in participants with SCN1A-positive Dravet syndrome aged 36 to <84 months (3 to <7 years). The study follows an open-label, dose-escalation design.
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.
To collect, preserve, and/or distribute annotated biospecimens and associated medical data to institutionally approved, investigator-directed biomedical research to discover and develop new treatments, diagnostics, and preventative methods for specific and complex conditions.
The present study aims to collect data regarding the history of the disease, previous and current treatments, and the clinical status of Dravet patients during the 3 months prior to stiripentol initiation, the first 3 months on stiripentol and the last 3 months on stiripentol (irrespective of stiripentol discontinuation).
Dravet Syndrome (DS) is a severe epileptic encephalopathy, which main cause is mutations of SCN1A, the gene coding for the Nav1.1 voltage-gated sodium channel. DS is characterized by childhood onset, severe cognitive deficit and drug-resistant seizures, including several generalized convulsive seizures per day, frequent status epilepticus and high seizure-related mortality rate. Sudden and unexpected death in epilepsy (SUDEP) represents the major cause of premature deaths. The risk of SUDEP is thus about 9/1000-person-year in comparison with about 5/1000-person-year in the whole population of patients with drug-resistant epilepsies. Experimental and clinical data suggest that SUDEP primarily result from a postictal central respiratory dysfunction. SUDEP in DS, might be the result of a seizure-induced fatal apnea in a patient who had developed epilepsy-related vulnerability to central autonomic and/or respiratory dysfunction. However, a key clinical issue which remains to be addressed is the temporal dynamics of the onset and evolution of the autonomic vulnerability in these patients. The main clinical risk factor of SUDEP is the frequency of convulsive seizures and the SUDEP risk can vary along the evolution of epilepsy. Although non-fatal seizure-induced ataxic breathing can be observed in patients with DS, whether or not repetition of seizures results in long-term alterations of breathing remains unclear. In the AUTONOMIC project, it will be investigate in a homogenous population of patients with DS the exact interplay between epilepsy-related cardiac and respiratory alterations on the one hand and the relation between the underlying neurodevelopmental disease, the repetition of seizure per se and these epilepsy-related autonomic alterations on the other hand. Autonomic functions will be investigated in the inter-ictal period (i.e. in the absence of immediate seizures, Work Package 1 (WP1)) and in the peri-ictal period, i.e. in the immediate time before, during (if possible) and after seizures (WP2). A multicenter cohort will be constituted, allowing to collect the inter-ictal and ictal cardio-respiratory data required in the 2 WP. The study will be sponsored by the Lyon's University Hospital. Patients will be recruited over a period of 24 months in one of the three participating clinical center. All patients will first enter in a prospective baseline period of 3 to 6 months duration in order to collect seizure frequency. After this period, all patients will then undergo a 24-48 hours video-EEG recordings as part of the routine clinical care. The monitoring will also include a full-night polysomnography. This patients will be eligible for inclusion in an extension follow-up study will monitor vital status every year in order to investigate long-term mortality, including SUDEP. The AUTONOMIC project will provide important results which will pave the way to develop and eventually validate therapeutic intervention to prevent SUDEP. By deciphering the exact interplay between epilepsy-related cardiac and respiratory alterations on the one hand and the relation between the underlying neurodevelopmental disease, the repetition of seizure per se and these epilepsy-related autonomic alterations on the other hand, the project will primarily deliver clinically relevant biomarkers.
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 follows an open-label, dose-escalation design, and Part 2 is a randomized, double-blind, sham delayed-treatment control, dose-selection study.
Dravet syndrome (DS) is an epileptic encephalopathy caused by pathogenic variants in the SCN1A gene resulting in medically refractory epilepsy and psychomotor delays. As a pilot study assessing for feasibility, the investigators aim to test whether alterations in cortical excitatory:inhibitory ratio can be reliably recorded. The investigators will utilize transcranial magnetic stimulation (TMS) metrics of cortical excitatory and inhibitory tone as an initial step towards translating findings from rodent genetic models of DS into disease-specific biomarkers and offer future measures of therapeutic target engagement in this patient population. Participants will complete two visits, each consisting of a TMS session and an EEG session. Visits will be scheduled 4-8 weeks apart.
The clinical trial "A Prospective Single-Center Single-Arm Clinical Trial on Cognitive Effect of Cannabidiol (CBD-OS®) on Dravet syndrome and Lennox-Gastaut Syndrome" is a single-group phase III study done in single tertiary referral center in Seoul, Korea. Chief investigator is Dr. Hoon-Chul Kang of Severance Hospital, Yonsei University College of Medicine. Associate investigators are Dr. Heung Dong Kim, Joon Soo Lee, Se Hee Kim, Han Som Choi, Ji Hoon Na, Dong Hwa Yang, and Hee Jung Kang, of Severance Hospital, Yonsei University College of Medicine. The aim of the study is to evaluate the effect of cannabidiol (CBD-OS®) on cognitive functions in patients aged from 2 to 18 years old diagnosed with Dravet syndrome or Lennox-Gastaut syndrome. The duration of study is planned as one year, after patient recruitment of 6 months. The intervention period in each patient is 24 weeks, with 2 weeks of medication titration, stabilization period of 10 weeks, and maintenance period of 12 weeks. The recruitment goal of patient number is 104, considering the study power of 90 percent. Primary outcomes are improvement of cognitive and development and improvement of seizure outcome. Secondary outcomes are improvement in behavior and quality of life. Safety monitoring criteria are adverse event profiles and physician's and caregiver's global assessment. Statistical analysis of outcomes is subject only to the patients who completed the 24-week medication and 2 times of tests before and after treatment of cannabidiol. Evaluation of seizure outcomes would include all patients who completed the 24-week medication and those who dropped out of the study, either by follow-up loss or discontinuation of medication due to incomplete seizure control or adverse effect of the medication. To evaluate safety, the investigators would measure adverse events and dropout rates by percentage. The investigators would analyze overall evaluation of the caregivers and investigator. Serious adverse events would be noted after causality evaluation.
