Study Summary

This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, multi-arm, multi-stage inpatient study designed to assess the efficacy, safety, tolerability, and pharmacokinetics (PK) of NBI-1117568 compared with placebo in adult subjects with a primary diagnosis of schizophrenia, who are experiencing an acute exacerbation or relapse of symptoms.

Primary Outcome

The PANSS evaluates the severity of various symptoms of schizophrenia, and is commonly used to measure symptom reduction in patients taking antipsychotics. Each item is scored on a 7-point severity scale (1=absent; 2=minimal; 3=mild; 4=moderate; 5=moderate severe; 6=severe; 7=extreme). The PANSS total score is derived from the summation of each item. A higher score indicates greater severity.
