Een studie van Soticlestat als aanvullende therapie bij kinderen en volwassenen met het syndroom van Dravet of het syndroom van Lennox-Gastaut
Een prospectieve, open-label, multisite, fase 3-uitbreiding van fase 3-onderzoeken om de veiligheid en verdraagbaarheid op lange termijn van Soticlestat als aanvullende therapie te beoordelen bij proefpersonen met het syndroom van Dravet of het syndroom van Lennox-Gastaut (ENDYMION 2)
Het belangrijkste doel van de studie is om te leren of soticlestat, wanneer gegeven als aanvullende therapie, het aantal aanvallen vermindert bij kinderen en volwassenen met het syndroom van Dravet (DS) of het syndroom van Lennox-Gastaut (LGS).
Deelnemers krijgen hun standaard anti-epileptische therapie, plus tabletten met soticlestat. Gedurende de hele studie zullen er geplande bezoeken en follow-uptelefoontjes zijn.

Interventie / Behandeling
Gedetailleerde beschrijving
Het medicijn dat in deze studie wordt getest, wordt soticlestat (TAK-935) genoemd. Soticlestat langdurig toegediend aan pediatrische en volwassen deelnemers die deelnamen aan een van de eerdere klinische fase 3-onderzoeken, TAK-935-3001 [NCT04940624] (deelnemers met DS) of TAK-935-3002 [NCT04938427] (deelnemers met LGS) zal worden beoordeeld op aanvullende veiligheids- en verdraagbaarheidsgegevens samen met werkzaamheidsanalyse.
De studie zal inschrijven ongeveer 376 deelnemers.
Alle deelnemers ontvangen soticlestat op basis van hun gewicht in de titratieperiode van 2 weken. Na de Titratieperiode blijven deelnemers dezelfde dosis krijgen in de Onderhoudsperiode. Aan het einde van de onderhoudsperiode wordt de dosis afgebouwd (tenzij de laagste dosis al is bereikt) en vervolgens gestopt. Deelnemers die de minimale dosis van 100 mg tweemaal daags (BID) niet verdragen, zullen uit het onderzoek worden gestaakt.
Deze multi-center studie zal wereldwijd worden uitgevoerd. De totale tijd om deel te nemen aan het onderzoek zal ongeveer 4 jaar zijn, of totdat het onderzoek wordt stopgezet naar goeddunken van de sponsor, of totdat het product is goedgekeurd voor marketing. Deelnemers die stoppen met de behandeling met het studiegeneesmiddel vóór de voltooiing van het onderzoek, zullen volgens protocol gevolgd blijven worden en een dagelijks aanvalsdagboek bijhouden tot het laatste follow-up telefoontje

Het is de verantwoordelijkheid van de onderzoeker om de klinische significantie te beoordelen; overleg met de medische monitor kan echter gerechtvaardigd zijn.
- Abnormale en klinisch significante ECG-afwijking bij bezoek 1 inclusief QT-interval met Fridericia-correctiemethode (QTcF) >450 milliseconden (ms) bevestigd met een herhaald ECG met handmatige meting van QTcF.

Number of Participants With At Least One Treatment Emergent Adverse Event (TEAE)
Tijdsspanne: Up to end of study (approximately 3.6 years)
|
An Adverse Event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment.
An AE was therefore any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it was considered related to the drug.
A TEAE was defined as any AE that started or increased in severity after the first dose of the study drug in this open label extension (OLE) study.

Number of Participants in Each Category of the Columbia-Suicide Severity Rating Scale (C-SSRS) Over Time
Tijdsspanne: At first visit post-baseline (Visit 1 [V1], Day 1 of the current study), Week 13 (V4), Week 26 (V5), Week 52 (V7), Week 78 (V9), Week104 (v11), Week 130 (V12) and Week 156 (V13)
|
C-SSRS systematically tracks suicidal ideation and behavior.
Responses to questions in the C-SSRS at baseline and each post-baseline time point were collected for participants ≥6 years of age.
C-SSRS incidences were categorized as follows: No Suicidal Ideation or Suicidal Behavior or Non-suicidal Self-injurious Behavior (No SI or SB or NSSJB), Non-suicidal Self-injurious Behavior (NSSJB), Suicidal Ideation (SI), and Suicidal Behavior (SB).
For each visit (V), the "Yes" answer to the question with the highest severity rank was used to determine the C-SSRS category of a participant.
The category Missing indicates the number of participants for whom no data was collected at the particular time point.
For each time point only categories with at least 1 participant are presented.
BL denotes Baseline and W denotes Week for the reported categories.

Number of Participants in Each Tanner Stage for Children 6 to 17 Years of Age During the Study
Tijdsspanne: From Baseline to Week 130
|
Tanner assessment scores were used to document the stage of development of puberty by assessing the secondary sexual characteristics, rated in 5 stages: Stage 1 (no development) to 5 (adult-like development in quantity and size) by age (6 to 17 years of age) and sex (boys and girls) during the study.
Tanner scale boy clinical classification test names for each stage are reported as follows: TANN02-Genitalia and TANN02-Pubic Hair.
Tanner scale girl clinical classification test names for each stage are reported as follows: TANN01-Breast and TANN01-Pubic Hair.

Absolute Value for Insulin-like Growth Factor 1 (IGF-1) for Children 2 to 17 Years of Age During the Study
Tijdsspanne: From Baseline to Week 130
|
Absolute values of IGF1 were summarized descriptively as a continuous variable by age and by sex (male and female).
If multiple assessments for a participant at different visits at a particular age were available, then the average of all data for that participant were used for the summary.

Number of Participants With Improvement in the Clinical Global Impression of Improvement (CGI-I) Score
Tijdsspanne: From Baseline to Week 156
|
The CGI-I Clinician is a 7-point Likert scale that the investigator uses to rate a participant's change in overall seizure control, behavior, safety and tolerability, after the initiation of study drug relative to Baseline (before treatment with study drug).
The participants were rated as follows: 1 (very much improved), 2 (much improved), 3 (minimally improved), 4 (no change), 5 (minimally worse), 6 (much worse), and 7 (very much worse).
Reported here is the number of participants with improvement, which includes the CGI-I responses: very much improved, much improved, minimally improved.

The Care GI-I is a 7-point Likert scale that the caregiver used to rate a participant's change in overall seizure control, behavior, safety and tolerability after the initiation of study drug relative to Baseline (before treatment with study drug).
The participants were rated as follows: 1 (very much improved), 2 (much improved), 3 (minimally improved), 4 (no change), 5 (minimally worse), 6 (much worse), and 7 (very much worse).
The parent/caregiver completed the Care GI-I via interview.

Number of Participants With Improvement in CGI-I Nonseizure Symptoms Score
Tijdsspanne: From Baseline to Week 156
|
The CGI-I nonseizure symptoms instrument is a series of single-item assessments that the investigator used to rate a participant's change in the caregiver-identified symptoms and impacts in select nonseizure domains since initiating the study drug.
The participants were rated on 7-point scale by the investigator as follows: 1 (very much improved), 2 (much improved), 3 (minimally improved), 4 (no change), 5 (minimally worse), 6 (much worse), and 7 (very much worse).
At Baseline, a symptoms form was completed by the clinician in collaboration with the primary caregiver to assess the participants status based on the presence of any nonseizure symptoms.
Reported here is the number of participants with improvement, which includes the CGI-I nonseizure symptoms responses: very much improved, much improved, minimally improved.

Change From Baseline in Quality of Life Inventory-Disability (QI-Disability) Score
Tijdsspanne: From Baseline to Week 156
|
The QI-Disability tool is a parent/caregiver-reported questionnaire that evaluates quality of life in children with intellectual disabilities.
It contains 32 items covering 6 domains of quality of life: physical health, positive emotions, negative emotions, social interaction, leisure and the outdoors, and independence.
Items were rated on a 5-point Likert scale and then transformed to a scale of 0 to 100.
Possible scores range from 0-100, with higher scores indicating better quality of life.
Negative change from baseline indicates worsening of quality of life.
