3. Severity of current episode of psychosis requires that the patient be hospitalized.
(Patients who are chronically hospitalized or in psychiatric daycare, whose hospitalization is for logistic reasons and not due to the severity of their illness, will be eligible for the study. )
4. Has a PANSS total score > 90 or a CGI-S rating of 7 (among the most extremely ill patients).
5. History or current diagnosis of other psychiatric or behavioral disorders that may interfere with the conduct or interpretation of the study.
6. Known suicidal risk, or a suicide attempt within the past 2 years, as assessed by the CDSS and/or by psychiatric history.
7. History of neuroleptic malignant syndrome, priapism or moderate or severe tardive dyskinesia.
8. An advanced, severe, or unstable disease of any type that may interfere with any of the study evaluations, including any medical condition that could be expected to progress, recur, or change to such an extent that it may bias the assessment of the clinical or mental status of the patient to a significant degree or put the patient at special risk (e.g., liver or kidney disease, severe uncontrolled asthma, malignancy).
9. Insulin-dependent diabetes mellitus. Patients with non-insulin-dependent diabetes will be eligible if the following criteria are satisfied: a.

13. Any clinically significant ECG abnormality, including a disorder of rate, rhythm, or conduction, or other morphological changes, or a QTcF interval prolongation (Fridericia’s correction formula) on the ECG (>450 msec for males; >470 msec for females). The 12-lead ECG will be used for determining the suitability of the patient for inclusion in the study (determination made by the Investigator). Values averaged from the 3 ECG measurements at baseline should be used in determining eligibility.
14. Vital signs (supine) outside the following ranges (measured after 5 minutes supine): a. Systolic blood pressure below 90 or above 150 mmHg; b. Diastolic blood pressure be
