Tutkimus Soticlestatista lisähoitona lapsille ja aikuisille, joilla on Dravetin oireyhtymä tai Lennox-Gastaut-oireyhtymä
Vaihe 3, tuleva, avoin, monipaikkainen, vaiheen 3 tutkimusten laajennus Soticlestatin pitkäaikaisen turvallisuuden ja siedettävyyden arvioimiseksi lisähoitona potilailla, joilla on Dravetin oireyhtymä tai Lennox-Gastaut-oireyhtymä (ENDYMION 2)
Tutkimuksen päätavoitteena on selvittää, vähentääkö lisähoitona annettu soticlestat kohtausten määrää Dravetin oireyhtymää (DS) tai Lennox-Gastaut'n oireyhtymää (LGS) sairastavilla lapsilla ja aikuisilla.
Osallistujat saavat tavallisen kouristushoitonsa sekä soticlestaattitabletteja. Suunniteltuja käyntejä ja jatkopuheluita tulee koko tutkimuksen ajan.

Interventio / Hoito
Yksityiskohtainen kuvaus
Tässä tutkimuksessa testattava lääke on nimeltään soticlestat (TAK-935). Soticlestatia annettiin pitkäaikaisesti lapsille ja aikuisille osallistujille, jotka osallistuivat jompaankumpaan edelliseen vaiheen 3 kliiniseen tutkimukseen, TAK-935-3001 [NCT04940624] (osallistujat, joilla on DS) tai TAK-935-3002 [NCT04938427] (osallistujat LGS:n kanssa) Arvioidaan lisäturvallisuus- ja siedettävyystietojen sekä tehoanalyysin kanssa.
Tutkimukseen otetaan mukaan noin 376 osallistujaa.
Kaikki osallistujat saavat soticlestaattia painonsa perusteella 2 viikon titrausjakson aikana. Titrausjakson jälkeen osallistujat saavat edelleen saman annoksen ylläpitojakson aikana. Ylläpitojakson lopussa annosta pienennetään (ellei jo ole alhaisin) ja lopetetaan sitten. Osallistujat, jotka eivät siedä vähimmäisannosta 100 mg kahdesti päivässä (BID), lopetetaan tutkimuksesta.
Tämä monikeskustutkimus suoritetaan maailmanlaajuisesti. Kokonaisaika tutkimukseen osallistumiseen on noin 4 vuotta tai kunnes tutkimus keskeytetään sponsorin harkinnan mukaan tai tuote on hyväksytty markkinointiin. Osallistujia, jotka lopettavat tutkimuslääkehoidon ennen tutkimuksen päättymistä, seurataan edelleen protokollan mukaisesti ja he pitävät päivittäistä kohtauspäiväkirjaa viimeiseen seurantapuheluun asti

Number of Participants With At Least One Treatment Emergent Adverse Event (TEAE)
Aikaikkuna: 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
Aikaikkuna: 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 With Improvement in the Clinical Global Impression of Improvement (CGI-I) Score
Aikaikkuna: 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
Aikaikkuna: 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
Aikaikkuna: 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.
