Outcome Measures
Primary Outcome Measures
- Change from Baseline in the Autism Behavior Inventory (ABI) Core Domain Score to Day 85 [Baseline up to Day 85]
Change from baseline in the ABI core domain score will be reported. ABI is a 62-item questionnaire completed on a web/mobile application or on paper. It is part of the Janssen Autism Knowledge Engine (JAKE), a research tool that tracks outcomes in Autism Spectrum Disorder (ASD). Each ABI item is 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 item is rated on a scale of 0-3 (never to very often [frequency] or not at all to without help [quality]). The ABI Core Domain Score is calculated as the sum of the scores in the Social Communication Domain and the Repetitive/Restrictive Behavior Domain divided by the total number of items in these 2 domains.
- Change from Baseline in ABI Social Communication Domain Score to Day 85 [Baseline up to Day 85]
Change from baseline in the ABI social communication domain score will be reported. Each item is rated on a scale of 0-3 (never to very often [frequency] or not at all to without help [quality]). The ABI social communication domain score is calculated as the sum of the scores in the social communication domain divided by the total number of items in this domain.
- Change from Baseline in ABI Repetitive/Restrictive Behavior (RRB) Domain Score to Day 85 [Baseline up to Day 85]
Change from baseline in the ABI RRB domain score will be reported. Each item is rated on a scale of 0-3 (never to very often). The ABI RRB domain score is calculated as the sum of the scores in the RRB domain divided by the total number of items in this domain.
Secondary Outcome Measures
- Change from Baseline in the ABI Mood and Anxiety Domain Score to Day 85 [Baseline up to Day 85]
Change from baseline in the ABI mood and anxiety domain score will be reported. The ABI mood and anxiety domain score is calculated as the sum of the scores in the mood and anxiety domain divided by the total number of items in this domain. Each item is rated on a scale of 0-3 (never to very often).
- Change from Baseline in the ABI Challenging Behavior Domain Score [Baseline up to Day 85]
Change from baseline in the ABI challenging behavior domain score will be reported. The ABI challenging behavior domain score is calculated as the sum of the scores in the challenging behavior domain divided by the total number of items in this domain. Each item is rated on a scale of 0-3 (never to very often).
- Change from Baseline in the ABI Self-Regulation Domain Score [Baseline up to Day 85]
Change from baseline in the ABI self-regulation domain score will be reported. The ABI self-regulation domain score is calculated as the sum of the scores in the self-regulation domain divided by the total number of items in this domain. Each item is rated on a scale of 0-3 (never to very often).
- Change from Baseline in the Aberrant Behavior Checklist (ABC) Subscales [Baseline up to Day 85]
Change from baseline in the ABC subscales will be reported. The ABC is a 58-item behavior rating scale used to measure behavior problems across 5 subscales: Irritability, Lethargy (Social Withdrawal), Stereotypy, Hyperactivity, Inappropriate Speech. Items are rated on a 4-point scale (ranging from 0 [not at all a problem] to 3 [the problem is severe in degree]).
- Change from Baseline in the Autism Behavior Inventory-Short Form (ABI-S) Scale Domains [Baseline up to Day 85]
Change from baseline in the ABI-S scale domains will be reported. ABI-S is the shorter version of the ABI. It consists of 24 items across 5 areas, social communication, RRB, mood and anxiety, challenging behavior, and self-regulation. Each ABI-S domain score is calculated as the sum of the scores in the ABI-S domain divided by the total number of items in this domain. Each item is rated on a scale of 0-3 (never to very often [frequency] or not at all to without help [quality]).
- Change from Baseline in the Autism Behavior Inventory-Clinician Interview (ABI-C) Domains [Baseline up to Day 85]
Change from baseline in the ABI-C domains will be reported. The ABI-C is designed to capture the behaviors of a person with ASD that have occurred over the past week. There are 14 items across each of the 5 domains (social communication, restrictive behaviors, mood and anxiety, self regulation and challenging behavior). The clinician rates the severity of behaviors and level of impairment on a scale of 1 (none) to 7 (very severe).
- Change from Baseline in the Clinical Global Impression-Severity (CGI-S) Scale Score [Baseline up to Day 85]
Change from baseline in the CGI-S scale score will be reported. The CGI-S rating scale is a global assessment that measures the clinician's impression of the severity of illness of the participant. A rating scale of 1-7 is used, with 1="normal, not at all ill" and 7="among the most extremely ill".
- Change from Baseline in the Repetitive Behavior Scale - Revised (RBS-R) Scale Score [Baseline up to Day 85]
Change from baseline in the RBS-R scale score will be reported. The RBS-R is a 43-item rating scale to indicate occurrence of repetitive behaviors and degree to which a behavior is a problem on a range between 0 to 3, where 0 = behavior does not occur and 3 = behavior occurs and is a severe problem.
- Change from Baseline in the Zarit Burden Interview (ZBI) Scale Score [Baseline up to Day 85]
Change from baseline in the ZBI scale score will be reported. The ZBI short version scale consists of 22 items designed to assess the psychological burden experienced by a caregiver. Responses range from 0-4, where 0 = never and 4 = nearly always.
- Change from Baseline in the Child Adolescent Symptom Inventory - Anxiety (CASI-Anx) Scale Score [Baseline up to Day 85]
Change from baseline in the CASI-Anx scale score will be reported. CASI-Anx is a 21-point anxiety subscale of the full CASI. Responses will range from 0 to 3, where 0 = never and 3 = very often.
- Change from Baseline in the Social Responsiveness Scale 2 (SRS-2) Score [Baseline up to Day 85]
Change from baseline in the SRS-2 scale score will be reported. The SRS-2 is a 65-item scale that measures social impairment and includes 5 subscales. Responses range from 1 to 4, where 1 = Not true and 4 = almost always true.
- Change from Baseline in the Caregiver Global Impression of Severity (Caregiver GI-S) [Baseline up to Day 85]
Change from baseline in the Caregiver GI-S scale score will be reported. The Caregiver GI-S is a single-item instrument that asks caregivers to rate their overall impression of the severity of their child's ASD symptoms. Responses range from 1 to 7, where 1 = None and 7 = Severe.
- Caregiver Assessment of Treatment Score [Day 85]
The Caregiver Assessment of Treatment is a 3-item questionnaire. Caregivers rate their global impression of improvement in their child's autism, whether there was improvement in specific symptoms, and their interest in having their child continue the study medication. One item uses a scale of 1 (very much improved) to 7 (very much worse), another item includes a Yes/No checklist, and another item uses a scale of 1 (not at all interested) to 5 (extremely interested).
- Self Global Impression of Improvement (Self GI-I) Score [Day 85]
The participant will be asked to give his/her impression of overall improvement in ASD symptoms using a single-item instrument, the Self GI-I. Responses will range from 1 to 7, where 1 = Very much better and 7 = Very much worse.
- Clinical Global Impression-Improvement (CGI-I) [Day 85]
The CGI-I is a single-item instrument that measures the clinician's global impression of improvement in the participant from the initiation of treatment. A 7-point scale is used, with 1=very much improved and 7=very much worse.
