Aseet ja interventiot
Osallistujaryhmä / Arm |
Interventio / Hoito |
|---|---|
|
Active Comparator: Ganaxolone Arm
Participants receives up to 20 weeks of Ganaxolone treatment
|
Liquid oral suspension of ganaxolone will be administered orally with food three times daily. Dosage will be increased based on tolerability, no more frequently than every 7 days. Dosing will be flexible and occur between 4 to 8 weeks, depending on tolerability and response across each individual patient. Once the maximum tolerated dose is identified, it will be held stable for the remaining 4-8 weeks of the study, for a total of 12 weeks in the randomized, controlled phase. The titration schedule for patients weighing 28 kg or less is: Days 1-7: 2 mg/kg x 3 per day Days 8-14: 4 mg/kg x 3 per day Days 15-21: 8 mg/kg x 3 per day Days 22-28: 14 mg/kg x 3 per day Day 29 and thereafter: 21 mg/kg x 3 per day The titration schedule for patients weighing more than 28 kg is: Days 1-7: 50 mg/kg x 3 per day Days 8-14: 100 mg/kg x 3 per day Days 15-21: 200 mg/kg x 3 per day Days 22-28: 400 mg/kg x 3 per day Day 29 and thereafter: 600 mg/kg x 3 per day |
|
Placebo Comparator: Placebo Arm
Participants receives up to 20 weeks of placebo treatment
|
The placebo suspension will contain the same components as the active compound, except for ganaxolone.

Mitä tutkimuksessa mitataan?
Ensisijaiset tulostoimenpiteet
Tulosmittaus |
Toimenpiteen kuvaus |
Aikaikkuna |
|---|---|---|
|
The score on irritability subscale on the Aberrant Behavior Checklist (ABC)
Aikaikkuna: The measures will be completed at screening, baseline, week 2, week 4, week 6, week 8, week 10, week 12, week 14, and week 16.
|
It is a common symptom of emotion dysregulation in ASD that impacts quality of life, including mental health, independence, educational opportunities, and integration into the community, and ganaxolone may provide more direct benefits or increased tolerability compared to atypical antipsychotics.
|
The measures will be completed at screening, baseline, week 2, week 4, week 6, week 8, week 10, week 12, week 14, and week 16.

Toissijaiset tulostoimenpiteet
Tulosmittaus |
Toimenpiteen kuvaus |
Aikaikkuna |
|---|---|---|
|
The score of Insistence on Sameness subscale of the Dimensional Assessment of Repetitive Behaviors (DARB)
Aikaikkuna: The measures will be completed at screening, baseline, week 2, week 4, week 6, week 8, week 10, week 12, week 14, and week 16.
|
The DARB is an informant report measure developed and validated following methods outlined by the NIH Patient-Reported Outcome Measurement Information System (PROMIS) framework.
Comprehensive, multi-trait, multi-method factor analyses across existing RRB instruments and meta-analysis of factor analyses identified the following eight RRB subdomains: repetitive motor behaviors, insistence on sameness, restricted interests, unusual interests, self-injurious behaviors, sensory sensitivity, obsessions and compulsions, and repetitive language.
|
The measures will be completed at screening, baseline, week 2, week 4, week 6, week 8, week 10, week 12, week 14, and week 16.
|
|
The score on irritability subscale on the Clinical Global Impressions Scale (CGI-IR)
Aikaikkuna: The measures will be completed at screening, baseline, week 2, week 4, week 6, week 8, week 10, week 12, week 14, and week 16.
|
The study physician will also administer the CGI scale, which includes clinical judgment of the severity of illness and global improvement.
The CGI is widely used in psychopharmacological studies and has high sensitivity to measure medication effects.
|
The measures will be completed at screening, baseline, week 2, week 4, week 6, week 8, week 10, week 12, week 14, and week 16.

The score on Insistence on Sameness subscale on the Clinical Global Impressions Scale(CGI-IS)
Aikaikkuna: These measures will be completed at screening, baseline, week 2, week 4, week 6, week 8, week 10, week 12, week 14, and week 16.
