About this study
In plain language
This study tests whether a long-acting shot of iloperidone helps keep schizophrenia symptoms from getting worse. It compares the drug with a placebo, a shot with no active medicine. The study is for adults ages 18 to 65 with schizophrenia who need ongoing mental health treatment.
The purpose of this research is to evaluate the efficacy of dosing iloperidone long-acting injection (LAI) compared to placebo in preventing the exacerbation of symptoms in patients with schizophrenia.
Compensation is read from the study's own description and may be missing — always confirm with the study team.
