About this study

In plain language

This study tests whether NBI-1117568 improves symptoms of schizophrenia better than a placebo, which has no active medicine. It is for adults with schizophrenia whose symptoms have gotten worse or returned and who need hospital care. Other study rules may also apply.

The primary objective for this study is to evaluate the efficacy of NBI-1117568 compared with placebo on improving behavioral and psychological symptoms of schizophrenia in adults.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
