What this trial studies

This study assesses the safety and tolerability of iloperidone, an antipsychotic medication, in adolescents aged 12 to 17 diagnosed with schizophrenia or bipolar I disorder. Participants will receive open-label treatment with iloperidone for up to 52 weeks, allowing researchers to monitor side effects and overall tolerability. The study aims to gather important data on how this medication affects younger patients, which is crucial for understanding its use in this age group.

Who should consider this trial

Good fit: Ideal candidates for this study are adolescents aged 12 to 17 who have a clinical diagnosis of schizophrenia or bipolar I disorder.

Not a fit: Patients who are currently using other investigational drugs or have a positive drug test may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the safe use of iloperidone for treating adolescents with serious mental health conditions.

How similar studies have performed: While studies on iloperidone have been conducted in adults, this specific focus on adolescents is relatively novel and has not been extensively tested.
