Change From Baseline to Day 85 in the Autism Behavior Inventory (ABI) Core Domain Score (Social Communication and Restrictive Behaviour)Primary· Baseline (Day 1) to Day 85
ABI:62-item questionnaire to track outcomes in autism spectrum disorder (ASD). Each item was answered on 1 of 2 possible dimensions: quality (how well person carries out particular behavior; 1 to 13 items) or frequency (how often particular behavior occurs; 14 to 62 items). Each item was rated on scale of 0 (never) to 3 (very often) for frequency and 0 (without help) to 3 (not at all) for quality. Higher score=severe symptoms/more frequency. ABI core domain score was from 2 domains: social communication (23 items; 3 sub-domains) and repetitive/restrictive behavior (RRB;15 items; 4 sub-domains)

Change From Baseline to Day 71 in the Autism Behavior Inventory-Short Form (ABI-S) Domains ScoresSecondary· Baseline (Day 1) to Day 71
The ABI-S was the shorter version of ABI. It consists of 24 items across 5 areas: challenging behavior (3 items), mood and anxiety (5 items), restrictive behaviors (7 items), social communication (6 items), and self-regulation (3 items). Each item was answered on 1 of 2 possible dimensions, quality (how well a person carries out a particular behavior or frequency (how often a particular behavior occurs). Each ABI-S domain score was calculated as the sum of the scores in the ABI-S domain divided by the total number of items in this domain. Each item was rated on scales of 0 (never) to 3 (very o

Change From Baseline to Day 85 in the Autism Behavior Inventory-Clinician Interview (ABI-C) Domains ScoresSecondary· Baseline (Day 1) to Day 85
The ABI-C covers the domains of ABI and was intended for completion by the clinician following an interview with caregiver and observation or interview with the individual with ASD, as appropriate. The ABI-C was designed to capture the behaviors of a person with ASD that have occurred over the past week. There were 14 items across each of the 5 domains: challenging behavior (2 items), mood and anxiety (2 items), restrictive behaviors (5 items), social communication (3 items), and self-regulation (2 items). The clinician rates the severity of behaviors or level of impairment on a scale of 1 (no

Change From Baseline to Day 85 in the Clinical Global Impression-Severity (CGI-S) Scale ScoreSecondary· Baseline (Day 1) to Day 85
The CGI-S 7-point scale was a global assessment that measures the clinician's impression of the severity of illness of the participant. A rating scale of 1 to 7 was used, with 1="normal, not at all ill" and 7="among the most extremely ill". Higher score indicated more severe illness.

There are 6 subscale scores: Stereotyped Behavior (items 1 to 6), self-injurious behavior (items 7 to 14), compulsive behavior (items 15 to 22), ritualistic behavior (items 23 to 28), sameness behavior (items 29 to 39), and restricted behavior (items 40 to 43). The ranges for RBS-R subscale scores were stereotyped behavior: 0 to 18; self-injurious behavior: 0 t

Change From Baseline to Day 85 in the Zarit Burden Interview (ZBI) Global ScoreSecondary· Baseline (Day 1) to Day 85
The ZBI short version scale consists of 22 items designed to assess the psychological burden experienced by a caregiver. Items ask how the caregiver felt and their responses range from 0 to 4, where 0 = never and 4 = nearly always. The ZBI global score was the sum of all item score and ranges from 0 to 88 with higher scores indicating a higher burden. A negative change in the ZBI global score from baseline representing improvement.
