简要总结
This is a single-arm pilot study to examine the impact of BXCL501 (sublingual film formulation of dexmedetomidine) administration on reducing the severity of undifferentiated acute agitation in patients presenting to the emergency department with underlying bipolar disorder or schizophrenia. This study is designed to evaluate BXCL501 for its FDA-approved indication -- treatment of agitation associated with bipolar disorder or schizophrenia -- applied in the emergency department setting.
详细描述
This pilot study will enroll 30 male and female adults with primary psychiatric complaint and a documented diagnosis of bipolar I disorder, bipolar II disorder, schizophrenia, schizoaffective disorder, or schizophreniform disorder, presenting to the emergency department with clinical signs of acute agitation. Eligible subjects will receive an initial dose of BXCL501 (180mcg) and a repeat dose (90mcg) 2 hours after the first BXCL501 dose in the event of persistent or recurrent agitation (up to two repeat doses) while under medical supervision in the emergency department. Efficacy and safety assessments will be conducted periodically before and after dosing.

结局指标
主要结局
Absolute change from baseline in the Altered Mental Status Scale (AMSS) score
时间窗: 120 minutes
AMSS is a 9-point scale ranging from -4 (most sedated) to 4 (most agitated).
次要结局
- Absolute change from baseline in the Behavioral Activity Rating Scale (BARS) score(120 minutes)
- Absolute change from baseline in the Richmond Agitation Sedation Scale (RASS) score(120 minutes)
- Absolute change from baseline in the Broset Violence Checklist (BVC) score(120 minutes)
- Times, in minutes, from BXCL501 administration to adequate sedation, defined as Altered Mental Status Scale (AMSS) score <1(To be determined - will be measured for 120 minutes)
- Times, in minutes, from BXCL501 administration to adequate sedation, defined as Richmond Agitation Sedation Scale (RASS) score <1(To be determined - will be measured for 120 minutes)
- Times, in minutes, from BXCL501 administration to adequate sedation, defined as Broset Violence Checklist (BVC) score <1(To be determined - will be measured for 120 minutes)
- Times, in minutes, from BXCL501 administration to adequate sedation, defined as Behavioral Activity Rating Scale (BARS) score <5(To be determined - will be measured for 120 minutes)
