E.3 | Principal inclusion criteria |
Screening and Open-label Stabilization Phase
1 Subject is ≥ 18 and ≤ 75 years of age, on the day of signing the informed consent.
2. Subject 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 using the SCID-CT)]. The duration of the subject’s illness whether treated or untreated must be ≥ 1 year.
3. Subject has had at least one prior episode of psychotic exacerbation as judged by the Investigator in the two years preceding screening.
4. Subject has a PANSS Total score ≥ 80 with a score ≥ 4 on 1 or more of any PANSS Positive subscale items at screening and open-label baseline (Visit 2).
5. Subject has a CGI-S score of ≥ 4 at screening and open-label baseline (Visit 2).
Double-blind Phase
1. a PANSS Total score ≤ 70 and a CGI-S score < 4 over at least 12 weeks with the allowance of two excursions (except during the last 4 weeks of the open-label phase) assessed at weekly study visits:
• An excursion is defined as a PANSS total score up to a maximum of 80 and CGI-S score up to a maximum of 4.
2. a PANSS item score of ≤ 4 (moderate or less) on all Positive subscale items and item G8 (uncooperativeness)
3. taking a stable dose of lurasidone for the last 4 weeks of the open-label phase.
|
|
E.4 | Principal exclusion criteria |
Screening and Open-label Stabilization Phase
1. Subject has 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.
2. Subject answers “yes” to “Suicidal Ideation” item 4 (active suicidal ideation with some intent to act, without specific plan) or item 5 (active suicidal ideation with specific plan and intent) on the C-SSRS assessment (at time of evaluation) at screening or baseline.
3. Subject demonstrates evidence of acute hepatitis, clinically significant chronic hepatitis, or evidence of clinically significant impaired hepatic function through clinical and laboratory evaluation.
4. Subject with Type 1 or Type 2 insulin-dependent diabetes.
5. Subject has any abnormal laboratory parameter at screening that indicates a clinically significant medical condition as determined by the Investigator.
6. Subject has a prolactin concentration > 100 ng/mL at screening or has a history of pituitary adenoma.
7. Subject is judged to be resistant to antipsychotic treatment defined as any one of the following:
a. failure to respond to > 2 marketed antipsychotic agents, given at an adequate dose and for an adequate duration (within the past 2 years)
b. history of treatment with clozapine for refractory psychosis
Double-blind Phase
1. Subject who in the Investigator’s judgment have been non-compliant with study medication and/or study assessments during the open-label stabilization phase. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Primary Efficacy Endpoint
1. An increase from double-blind phase baseline in both PANSS Total score of ≥ 25% (see Appendix 7) and a CGI-S worsening of ≥ 1 point, for two consecutive visits, occurring no more than 10 days apart.
2. At any single visit a PANSS item score of ≥ 5 (moderately severe) on hostility or uncooperativeness, or a PANSS item score ≥ 5 on ≥ 2 items of unusual thought content, delusions, conceptual disorganization, or hallucinatory behavior.
3. Initiation of any of the following treatment interventions, for any reason, including worsening schizophrenia, deliberate self injury /aggressive behavior or suicidal ideation:
a) the initiation of an antipsychotic agent (other than the study drug lurasidone)
b) the initiation or need for an increase in dose of an antidepressant or mood stabilizer
c) an increase of lorazepam (or equivalent) dosage ≥ 2 mg/day for a minimum of 3 days relative to the previous dose
d) transfer to an increased level or increased intensity of psychiatric care
e) initiation of electroconvulsive therapy.
4 Insufficient clinical response (or exacerbation of underlying disease) reported as an adverse event as determined by the Principal Investigator.
5 Deliberate self-injury or repeated aggressive behavior; active suicidal or homicidal ideation or attempt.
6 Psychiatric hospitalization (voluntary or involuntary) due to worsening schizophrenia. |
