Studie Soticlestatu jako přídavné terapie u dětí a dospělých s Dravetovým syndromem nebo Lennox-Gastautovým syndromem
Fáze 3, prospektivní, otevřená, vícemístná, rozšíření studií fáze 3 k posouzení dlouhodobé bezpečnosti a snášenlivosti Soticlestatu jako doplňkové terapie u subjektů s Dravetovým syndromem nebo Lennox-Gastautovým syndromem (ENDYMION 2)
Hlavním cílem studie je zjistit, zda soticlestat, pokud je podáván jako doplňková terapie, snižuje počet záchvatů u dětí a dospělých s Dravetovým syndromem (DS) nebo Lennox-Gastautovým syndromem (LGS).
Účastníci dostanou svou standardní protizáchvatovou terapii plus tablety soticlestatu. Během studie budou probíhat plánované návštěvy a následné telefonáty.

Detailní popis
Lék testovaný v této studii se nazývá soticlestat (TAK-935). Soticlestat podávaný dlouhodobě u pediatrických a dospělých účastníků, kteří se účastnili některé z předchozích klinických studií fáze 3, TAK-935-3001 [NCT04940624] (účastníci s DS) nebo TAK-935-3002 [NCT04938427] (účastníci s LGS) být posouzeny pro další údaje o bezpečnosti a snášenlivosti spolu s analýzou účinnosti.
Studie se zúčastní přibližně 376 účastníků.
Všichni účastníci obdrží soticlestat na základě jejich hmotnosti během 2týdenního titračního období. Po období titrace budou účastníci nadále dostávat stejnou dávku v udržovacím období. Na konci udržovacího období bude dávka snižována (pokud již nebyla na nejnižší dávce) a poté zastavena. Účastníci, kteří netolerují minimální dávku 100 mg dvakrát denně (BID), budou ze studie vyřazeni.
Tato multicentrická zkouška bude probíhat po celém světě. Celková doba účasti ve studii bude přibližně 4 roky, nebo dokud nebude studie podle uvážení zadavatele zastavena nebo dokud nebude produkt schválen k uvedení na trh. Účastníci, kteří přeruší léčbu studovaným lékem před dokončením studie, budou nadále sledováni podle protokolu a budou si vést denní deník záchvatů až do posledního následného telefonátu

Number of Participants With At Least One Treatment Emergent Adverse Event (TEAE)
Časové okno: 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

|
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
Časové okno: 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 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
Časové okno: 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.

Number of Participants With Improvement in CGI-I Nonseizure Symptoms Score
Časové okno: 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
Časové okno: 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.
