Participants with history of schizophrenia or other chronic psychosis are excluded. • Within 1 year before the screening visit or between screening and randomization, any of the following: myocardial infarction; moderate or severe congestive heart failure, New York Heart Association class III orIV; hospitalization for, or symptoms of, unstable angina; syncope due to orthostatic hypotension or unexplained syncope; known significant structural heart disease (such as, significant valvular disease, hypertrophic cardiomyopathy); or hospitalization for arrhythmia. • Congenital QT prolongation. • Intermittent second- or third-degree atrioventricular (AV) heart block or AV dissociation or history of ventricular tachycardia. • A corrected QT (QTcF) interval measurement >470 milliseconds (men and women) at screening (as determined at the investigational site). • History of malignant cancer within the last 5 years. • History of vitiligo and/or current evidence of post-inflammatory hypopigmentation. • Calculated creatinine clearance <30 milliliters per minute (Cockcroft- Gault formula; Cockcroft and Gault 1976) at screening. • Currently enrolled in any other clinical trial involving an investigational product or any other type of medical research judged not to be scientifically or medically compatible with this study. |
