What this trial studies

This study evaluates the efficacy and safety of BXCL501 in treating acute agitation in children and adolescents aged 10-17 with bipolar disorder or schizophrenia. Approximately 140 participants will be randomized to receive either BXCL501 at different dosages or a placebo. The study will take place in a clinical research setting or hospital, where subjects will be monitored for their agitation levels and overall health. Efficacy and safety assessments will be conducted periodically throughout the study.

Who should consider this trial

Good fit: Ideal candidates are children and adolescents aged 10-17 with a diagnosis of bipolar disorder or schizophrenia who are experiencing acute agitation.

Not a fit: Patients whose agitation is due to substance intoxication or those at significant risk of suicide may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new option for managing acute agitation in pediatric patients with serious mental health conditions.

How similar studies have performed: While this approach is novel in the pediatric population, similar studies in adults have shown promising results with BXCL501.
