About this study
Official title: A Randomized, Double-blind, Placebo-controlled Study to Determine Efficacy and Safety of BXCL501 in Agitation Associated With Pediatric Schizophrenia and Bipolar Disorder
This is a study of the efficacy and safety of BXCL501 in children and adolescents with acute agitation and either bipolar disorder or schizophrenia.
Read the detailed description
The study will enroll approximately 140 subjects randomized to dose regimens of 80 µg or 120 µg BCXL501 or placebo (Group one), or 60 µg BCXL501 or placebo (Group two; Europe only). Subjects with acute agitation will include male and female children and adolescents who are either newly admitted to a hospital setting or already admitted and experiencing acute agitation. Subjects will be domiciled in a clinical research setting or hospitalized to remain under medical supervision while undergoing screening procedures to assess eligibility. Efficacy and safety assessments will be conducted periodically before and after dosing.

What is being measured
The primary outcome is the main question the study is designed to answer.
Absolute change from baseline in the Positive and Negative Syndrome Scale - Excited Component (PEC) total score
The Positive and Negative Syndrome Scale - Excited Component (PEC) comprises 5 items associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (minimum) to 7 (maximum). The PEC, the sum of these 5 subscales, thus ranges from 5 (absence of agitation) to 35 (extremely severe)
Measured: 120 minutes - Group one only
