Brief Summary

This is a definitive study to support the safety and efficacy evaluation of BXCL501 for the acute treatment of agitation in schizophrenia. The BXCL501-301 study is designed to characterize the efficacy, safety and tolerability of BXCL501 (sublingual film formulation of DEX, HCl) in agitation associated with schizophrenia, schizoaffective disorder or schizophreniform disorder.

Outcome Measures

Primary Outcomes (1)

Change From Baseline in the Positive and Negative Syndrome Scale- Excited Component (PEC) Total Score
The Positive and Negative Syndrome Scale-Excited Component (PEC) includes 5 items-poor impulse control, tension, hostility, uncooperativeness, and excitement-each of which is rated from 1 (minimum) to 7 (maximum); the sum of these 5 items, the PEC total score, ranges from 5 (absence of agitation) to 35 (extremely severe).
Baseline and 2 hours

Secondary Outcomes (1)

Change From Baseline in the Positive and Negative Syndrome Scale- Excited Component (PEC) Total Score Over Time
