NCT ID: NCT06395792 Not yet recruiting - Clinical trials for Dravet Syndrome (DS)

A Study on Dravet Syndrome (DS) and Lennox-Gastaut Syndrome (LGS) in Children, Teenagers and Adults in Portugal

DRALEGA-PT
Start date: April 30, 2024
Phase:
Study type: Observational

The main aim of this study is to learn about the percentage of persons diagnosed with Dravet Syndrome (DS) and Lennox-Gastaut-Syndrome (LGS) in 2022 and of persons newly diagnosed in 2021 and 2022 compared to the overall population in Portugal. Other aims are to understand how many percent of the persons diagnosed with DS and LGS are children, teenagers or adults and gather additional information on diagnosis and persons diagnosed with DS and LGS in Portugal. Information will be taken from a participant's existing medical hospital records. It is planned to review data in approximately 3 public hospitals in Portugal. No personal information of the participants will be collected.

Fenfluramine for Adult Dravet Patients

Start date: December 10, 2022
Phase: Phase 3
Study type: Interventional

Full Title: Fenfluramine for the treatment of refractory Epilepsy in Adult Dravet patients Short Title: Fenfluramine for Adult Dravet patients Clinical Phase: Phase III Sample Size: A total of 15 participants will be included in the study. Study Population: Adult patients (18 years and older) with drug-resistant epilepsy (maintained on their existing medications, with exception of cannabidiol) and genetically confirmed Dravet syndrome will be recruited to participate in the study. Accrual Period: 12 months Study Design: Open label, non-randomized and uncontrolled add-on trial in adults (18 years of age and older) residing in Ontario, with refractory motor seizures and maintained on their existing antiepileptic medications, with exception of cannabidiol.

All doses are divided to twice a day. Duration: Baseline phase: 4 weeks (no study drug) Titration phase: 2 weeks (if not taking stiripentol) to 3 weeks (if the patient is taking stiripentol) Treatment phase: 12 weeks Extension phase: up to 38 weeks, for patients who had at least a 50% decrease in seizure frequency Post-trial washout phase: 2 weeks (if not taking stiripentol) to 3 weeks (if the patient is taking stiripentol) Route of administration: Oral Efficacy and safety points of interest - Monthly convulsive seizure frequency (MCSF) reduction ≥ 50% - Improvement in motor function - Improvement in Cognition and Behavior - Improvement in Quality of Sleep - Improvement in Quality of life - Determination of Cardiovascular safety in adults - Responder analysis (≥25%, ≥75%, or 100% reduction in mean MCSF) - Longest period of seizure freedom - Number of Emergency room visits - Use of rescue medication (number of days in 28 day-periods) - Duration of post-ictal stage - Frequency of other seizure types - Body weight changes - Patient's global functioning prior to and after study (Clinical Global Impressions Scale) Trial registration: www.clinicaltrials.gov

Multicentre Real-life Follow-up Study of Rare Epileptic Syndromes in Children and Adolescents

EPIRARE
Start date: December 2021
Phase:
Study type: Observational

Rare epilepsies as a whole account for 20-30% of epilepsies, but knowledge about prognostic factors is currently limited. This means that it is difficult to provide adequate information to families at diagnosis and during follow-up. Prognostic factors are also important for management as they can have an impact on the patient's outcome (time to intervention, choice of one molecule over another, etc.). Finally, few treatments are currently available for these epilepsies. One of the limitations to the development of treatments is the lack of real life data as it is difficult to create reliable primary endpoints such as the rate of patients becoming seizure free naturally compared to a therapeutic intervention. The aim of this real-life study is to evaluate the response to treatment as well as to see the evolution of cognitive and psychiatric comorbidities. As explained above, there are very few randomised trials except for 3 rare epilepsies (infantile spasm syndrome, Dravet syndrome, Lennox-Gastaut syndrome). This has led to the virtual absence of management recommendations, including for the three syndromes mentioned above, where attempts at treatment algorithms have been proposed, although these have not been able to be considered as evidence-based recommendations. As a result, there is some diversity in the management of rare epilepsies from one centre to another. However, this diversity in management can be an asset in a real-life study. This will make it possible to compare different management methods, both in terms of seizure control and medium-term outcome.
