Study Endpoints
Primary Endpoints
Frequency of occurrence of treatment-emergent adverse events (TEAEs).
Baseline up to Day 362
Change from Baseline in Autism Behavior Inventory (ABI)-Social Communication Domain Score
Baseline up to Day 110

Change from baseline in the ABI-Social Communication Domain Score will be reported. The ABI is a 62-item questionnaire for reporting the behaviors of subjects (ages: 3 years-adulthood) diagnosed with ASD. The tool is suitable for completion by parents or care/study partners of people with ASD. Each item assesses either quality (from not at all to without help) or frequency (never to very often) of a particular behavior. The Social Communication domain score is the sum of the scores in the social communication domain divided by the number of items in the domain.

Secondary Endpoints
Frequency of occurrence of Serious Adverse Events (SAEs)
Baseline up to Day 362
Frequency of occurrence of TEAEs leading to discontinuation.
Baseline up to Day 362
Frequency of occurrence of TEAEs arising from clinically important changes in other safety assessments.
Baseline up to Day 362
