Assessment of Safety of the Use of Fenfluramine in Children With Dravet Syndrome Under 24 Months of Age
United States5 participantsStarted 2024-10-22
Plain-language summary
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 an intermediate size patient population expanded access protocol to allow access to fenfluramine for children under 24 months of age.

Inclusion criteria
. SCN1A with a known or presumed pathogenic variant or VUS with a history of prolonged seizure or a clinical diagnosis of Dravet syndrome.
. Failure of at least one anti-seizure medication that is not a sodium channel blocker (lamotrigine, oxcarbazepine, carbamazepine, eslicarbazepine)
Exclusion criteria
. Patients with mild or greater mitral valve regurgitation and/or trace or greater aortic valve regurgitation will not be eligible for participation. The clinical statement can be submitted first for initial, conditional approval and then ECHO results can be submitted at a later date for final approval.
. Patients with failure to thrive will not be eligible for participation as fenfluramine can suppress appetite and has a risk for weight loss. Failure to thrive will be evaluated on the following criteria:
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
