Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study doctors to understand how your current medications might interact with the trial.

What data supports the effectiveness of the drug Cariprazine for Autism Spectrum Disorder?

Cariprazine, a drug approved for schizophrenia and bipolar disorder, showed numerical improvement in behavior assessments in a study with children with autism, suggesting potential benefits for autism symptoms.12345

Is Cariprazine safe for use in humans?

Cariprazine has been studied for safety in both adults and children, showing that it is generally well tolerated. Common mild or moderate side effects include weight gain, increased appetite, dizziness, and nasal congestion, with some reports of movement-related symptoms that resolved without stopping the treatment.23456

How is the drug Cariprazine unique for treating Autism Spectrum Disorder?

Cariprazine is unique because it is a dopamine D3-preferring D3/D2 receptor partial agonist, which means it works by balancing certain brain chemicals differently than other treatments. It is being explored for Autism Spectrum Disorder (ASD) as there are currently no approved medications specifically for the core social and behavioral deficits in ASD.12345

What is the purpose of this trial?

This trial is testing a new drug called cariprazine to see if it can help reduce irritability in children and teenagers with autism. The study involves taking the drug daily for a period of time and includes regular check-ups to monitor safety and effectiveness. The goal is to find out if cariprazine can improve behavior in young people with autism. Cariprazine has shown potential in alleviating core behavioral deficits and hyperactivity in animal models of autism spectrum disorder.

Eligibility Criteria

This trial is for children aged 5-17 with Autism Spectrum Disorder (ASD) who show significant irritability. They must have specific scores on clinical assessments that measure severity of irritability and confirm an ASD diagnosis. Participants will be randomly assigned to receive either the drug Cariprazine or a placebo.

Inclusion Criteria

You have a score of 4 or more on the CGI-S Irritability subscale at screening.
Participants at the time of screening must have a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnosis of ASD, confirmed by Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime (K-SADS-PL) administered at screening (Visit 1) by a trained clinician.
Participants must have an Aberrant Behavior Checklist, 2nd edition - Community Version - Irritability (ABC-I) subscale score ≥ 18 (Visits 1 and 2).

Treatment Details

Interventions

  • Cariprazine
  • Placebo
Trial Overview The study tests Cariprazine's safety and effectiveness in reducing irritability due to ASD compared to a placebo, over an 8-week treatment period followed by a 12-week safety follow-up. This double-blind trial means neither participants nor doctors know who receives the actual drug or placebo.

Findings from Research

In clinical trials, cariprazine significantly improved schizophrenia symptoms compared to placebo, as measured by the Positive and Negative Syndrome Scale (PANSS), and showed a longer time to relapse in a long-term study.
Cariprazine was more effective than risperidone in treating negative symptoms of schizophrenia, which are often challenging to address, and it was generally well tolerated with mostly mild to moderate side effects.
Cariprazine: A Review in Schizophrenia.Garnock-Jones, KP.[2018]
Cariprazine (Vraylar) is an atypical antipsychotic that acts as a partial agonist at dopamine D3 and D2 receptors, with a preference for D3, and also affects serotonin 5-HT1A receptors, which contributes to its therapeutic effects.
Approved in the USA in September 2015, cariprazine is used to treat schizophrenia and acute manic or mixed episodes in bipolar I disorder, and is being explored for additional uses in treating negative symptoms of schizophrenia and bipolar depression.
Cariprazine: First Global Approval.McCormack, PL.[2018]
Cariprazine is effective for treating schizophrenia and bipolar I disorder, showing a favorable side effect profile due to its selective affinity for D3 receptors, which helps address a range of symptoms including negative and cognitive symptoms.
It has a longer half-life and a delayed relapse time compared to other second-generation antipsychotics, making it a potentially better option for patients with high rates of non-adherence and frequent relapses.
