| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The primary objective of this study is to evaluate the efficacy of low-dose lurasidone (20 mg/day) compared to placebo in acutely psychotic subjects with schizophrenia. |
|
| E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are:
- to evaluate the tolerability and safety of lurasidone 20 mg/day compared to placebo,
-to evaluate the efficacy, tolerability and safety of subjects initially assigned to lurasidone 80 mg/day compared to placebo (assay sensitivity arm),
- to evaluate the efficacy of lurasidone 80 mg/day versus 160 mg/day in early non-responders and
- to evaluate the efficacy of lurasidone 80 mg/day and 160 mg/day in early non-responders compared to placebo. |

| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
| Subject is ≥ 18 and ≤ 75 years of age, and meets DSM-IV-TR criteria for a primary diagnosis of schizophrenia [including disorganized (295.10), paranoid (295.30), undifferentiated (295.90) subtypes] as established by clinical interview (using the DSM-IV-TR as a reference and confirmed by the SCID-CT). The duration of the subject’s illness whether treated or untreated must be ≥ 6 months. Subject has a PANSS total score ≥ 80 and PANSS subscale score ≥ 4 (moderate) on 2 or more of the following PANSS subscale items: delusions, conceptual disorganization, hallucinations, and unusual thought content at screening and baseline and a CGI-S score of ≥ 4 at screening and baseline. Subject has an acute exacerbation of psychotic symptoms (no longer than 2 months) and marked deterioration of function from baseline (by history) or subject has been hospitalized for the purpose of treating an acute psychotic exacerbation for 2 consecutive weeks or less immediately before screening. |
|
| E.4 | Principal exclusion criteria |
| Diagnosis of a DSM-IV Axis I or Axis II diagnosis, other than schizophrenia, that has been the primary focus of treatment within 3 months of screening. Considered by the investigator to be at imminent risk of suicide or injury to self, others, or property. |
|
