Cariprazine is a dopamine D-preferring D/D and serotonin 5-HT receptor partial agonist approved to treat adults with schizophrenia and manic/mixed or depressive episodes associated with bipolar I disorder. This study, which is the first to evaluate cariprazine in pediatric patients with autism spectrum disorder (ASD) (including children 5-9 years of age) using an oral solution formulation, evaluated the safety, tolerability, pharmacokinetics (PK), and exploratory efficacy of cariprazine and its two major active metabolites, desmethyl cariprazine (DCAR) and didesmethyl cariprazine (DDCAR). This clinical pharmacology, open-label, multiple-dose study enrolled 25 pediatric patients from 5 to 17 years of age, who met the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria for ASD.

Cariprazine is a dopamine D-preferring D/D and serotonin 5-HT receptor partial agonist approved to treat adults with schizophrenia and manic/mixed or depressive episodes associated with bipolar I disorder. This sequential-cohort, dose-escalation study was the first to evaluate the pharmacokinetic, safety, and tolerability profile of cariprazine and its two major active metabolites, desmethyl-cariprazine (DCAR) and didesmethyl-cariprazine (DDCAR), in pediatric patients with schizophrenia or bipolar I disorder. This phase I open-label study enrolled patients with schizophrenia (13-17 years of age) or bipolar I disorder (10-17 years of age).
