GroupInterventionDescription
ML-004 (IR)/(ER) tabletML-004 (IR)/(ER) tabletML-004 is a bilayer immediate-release (IR)/extended-release (ER, gastroretentive) oral tablet formulation. ML-004 is taken orally once daily and provided as a tablet in two dose strengths of 12 mg (3 mg IR/9 mg ER) and 24 mg tablet (6 mg IR/18 mg ER). Dose levels for this study are 12 mg (provided as one 12 mg tablet), 24 mg (one 24 mg tablet), 48 mg (two 24 mg tablets), and 72 mg (three 24 mg tablets).
ML-004 PlaceboML-004 PlaceboMatched placebo oral tablets will consist of same excipients as the investigational drug but without any ML-004. Placebo taken orally once daily to match tablet number of ML-004 dose levels for 12 mg (1 tablet), 24 mg (1 tablet), 48 mg (2 tablets), and 72 mg (3 tablets).
Primary Outcome Measures
NameTimeMethod
Change from Baseline in Autism Behavior Inventory (ABI)-Social Communication Domain ScoreBaseline 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 Outcome Measures
NameTimeMethod
Change from Baseline in Clinician Global Impression of Improvement (CGI-I)Day 110

The CGI-I score is a single-item instrument based on a 7-point scale routinely used in clinical trials to capture the Investigator's global impression of response. The Investigator or designee rates the improvement observed from 1 (very much improved) to 7 (very much worse).

Change from Baseline in Autism Behavior Inventory-Clinician (ABI-C) ScoreBaseline up to Day 110

The ABI-Clinician (ABI-C) captures the clinician rating of behaviors of a person with ASD that occurred over the week prior to assessment. It contains 14 items reflecting the core and associated autism behavior domains: Social Communication, Restrictive Behaviors, Mood and Anxiety, Self Regulation, and Challenging Behavior. Each item is rated on a 7-point scale from 1 (none; no symptoms present) to 7 (very severe; persistent interference with function or adaptation).

Change from Baseline in Aberrant Behavior Checklist 2-Irritability (ABC-I) Subscale ScoreBaseline up to Day 110

The ABC is a parent- or care/study partner-reported behavior rating assessment with five domains and 58 items, each rated on a 0 (not at all a problem) to 3 (the problem is severe in degree) scale. The irritability domain consists of 15 items.

Change from baseline in the Clinician Global Impression of Severity (CGI-S) ScoreBaseline up to Day 110

The CGI-S is a global assessment of the clinician-rater's impression of the severity of the participant's illness. It is rated on a scale of 1 (normal, not at all ill) to 7 (among the most extremely ill).

Change from baseline in the ABI Self-regulation Domain ScoreBaseline up to Day 110

Each item on the ABI- Self-regulation Domain is rated by frequency (never to very often). The domain score is the sum of all domain items scores divided by the number of items in the domain.

Change from baseline in the ABI-Short Form (ABI-S) ScoreBaseline up to Day 110

The ABI-S is a 24-item short version of the ABI, containing items from each of the five domains. The domain score for each domain is calculated as the sum of scores all domain items divided by the number of items in the domain.

Change from baseline in the ABC-Social Withdrawal (ABC-SW) Subscale ScoreBaseline up to Day 110

The ABC-SW subscale consists of 16 items of the ABC-2 rated from 0 (not at all a problem) to 3 (the problem is severe in degree).

Change from baseline in the Social Responsiveness Scale 2 (SRS-2) ScoreBaseline up to Day 110

The SRS-2 consists of 65 items across 5 subscales. Responses range from 1 (not true) to 4 (almost always true).

Change from baseline in the Vineland-3 (Domain Level Version) Score: total of Communication, Socialization, and Maladaptive behavior domainsBaseline up to Day 110

The Vineland-3 Domain Level Version contains 5 domains. Responses on each item are rated from 0 (never) to 2 (usually).

Change from baseline in the ABI Repetitive/Restrictive Behavior Domain ScoreBaseline up to Day 110

Each item on the ABI-Repetitive/Restrictive Behavior Domain is rated by frequency (never to very often). The domain score is the sum of all domain items scores divided by the number of items in the domain.

Change from baseline in the ABI Mood and Anxiety Domain ScoreBaseline up to Day 110

Each item on the ABI- Mood and Anxiety Domain is rated by frequency (never to very often). The domain score is the sum of all domain items scores divided by the number of items in the domain.

Change from baseline in the ABI Challenging Behavior Domain ScoreBaseline up to Day 110

Each item on the ABI- Challenging Behavior Domain is rated by frequency (never to very often). The domain score is the sum of all domain items scores divided by the number of items in the domain.
