Brief Summary:

Autism spectrum disorder (ASD) consists of deficits in social, communication, and cognitive development, repetitive and stereotypic behaviors. Many ASD patients show notably high levels of irritability, including verbal and physical aggression, self injury, and/or property destruction. Autistic infants tend to avoid eye contact and show little interest in others. This study will assess how safe and effective cariprazine is in treating pediatric participants (5 to 17 years of age) with ASD. Adverse events and change in disease activity will be assessed.

Cariprazine is an investigational drug being developed for the treatment of irritability due to ASD. This study is double-blinded means that neither the participants nor the study doctors will know who will be given cariprazine and who will be given placebo (does not contain treatment drug). Study doctors put the participants in 1 of the 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. Approximately 152 participants diagnosed with ASD will be enrolled in approximately 40 sites in the United States.

Participants will receive oral capsules or oral solution of cariprazine or placebo once daily for 8-weeks and will undergo a 12-week safety follow-up period.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.

Primary Outcome Measures :
  1. Change from Baseline in Aberrant Behavior Checklist, 2nd edition - Community Version - Irritability (ABC-I) Subscale Score [ Time Frame: Baseline (Week 0) to Week 8 ]
    The Aberrant Behavior Checklist (ABC) - Community version is a 58-item, caregiver-rated scale designed to measure inappropriate and maladaptive behavior of people with developmental disabilities (including intellectual disability and ASD). The ABC has 5 subscales (Irritability, Social Withdrawal, Stereotypic Behavior, Hyperactivity and Inappropriate Speech). The caregiver rates the child's behavior from 0=not at all a problem to 3= the problem is severe in degree. The range for Irritability is 0 to 45. Higher scores indicate greater severity.


Secondary Outcome Measures :
  1. Percentage of Participants with responder status of "Very Much Improved" or "Much Improved" on the Clinical Global Impression- Change Irritability (CGI-C Irritability) Scale [ Time Frame: Week 8 ]
    The Clinical Global Impression - Change-Irritability (CGI-C Irritability) is a single-item rating scale that assesses change in the severity of a participant's irritability from the clinician's perspective. The CGI-C Irritability 7-point graded response scale (1 = "Very much improved," 2 = "Much improved," 3 = "Minimally improved," 4 = "No change," 5 = "Minimally worse," 6 = "Much worse," or 7 = "Very much worse").

  2. Change from Baseline in Parent-Rated Anxiety Scale for Youth with Autism Spectrum Disorder (PRAS-ASD) Total Score [ Time Frame: Baseline (Week 0) to Week 8 ]
    PRAS-ASD is a 25-item caregiver-reported measure of anxiety in participants aged 3 to 17 with ASD. All items use a 4-point response scale: 0 = "None (not present);" 1 = "Mild (present sometimes, not a real problem);" 2 = "Moderate (often present and a problem);" 3 = "Severe (very frequent and a major problem)." Total score ranges from 0 to 75, with higher scores indicating greater severity of anxiety.

  3. Change from Baseline in Caregiver Strain Questionnaire Short Form 7-Item (CGSQ SF-7) total score [ Time Frame: Baseline (Week 0) to Week 8 ]
    CGSQ SF-7 is a caregiver-reported 7-item measure of self-reported strain that focuses on the impact of caring for a child with emotional and behavioral problems. Responses are scored on a 5-point scale (1 = "Not at all," 2 = "A little;" 3 = "Somewhat;" 4 = "Quite a bit;" and 5 "Very much") with higher scores indicating greater caregiver strain.
