简要总结
Phase 3 safety and efficacy study of Staccato Loxapine in the treatment of acute agitation in schizophrenic patients
详细描述
This is an in-clinic, multi-center, randomized, double-blind, placebo-controlled study of 2 dose levels of Staccato Loxapine, 5 and 10 mg. Patients may receive up to 3 doses of study drug in a 24-hour period, depending on their clinical status. The primary endpoint is the change from baseline in the PANSS (Positive and Negative Symptom Scale) Excited Component (also known as PEC) score, performed at 2 hours after the first dose.

结局指标
主要结局
Change in PANSS-EC From Baseline
时间窗: Baseline and 2 hours
The Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) comprises 5 items associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (min) to 7 (max). The PANSS-EC, the sum of these 5 subscales, thus ranges from 5 to 35. Individuals were eligible if they had a PANSS-EC of ≥14 (out of 35) and a score ≥4 (out of 7) on at least 1 of the 5 items.
次要结局
