Lurasidone HCl is a compound being developed for the treatment of schizophrenia. This clinical study is designed to test the hypothesis that lurasidone is effective, tolerable, and safe as compared with quetiapine XR long term among schizophrenic outpatients with chronic schizophrenia.

Condition Intervention Phase
Chronic Schizophrenia Drug: Lurasidone HC1 Drug: Quetiapine XR Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase 3 Randomized, Double-Blind, Active Comparator-Controlled Clinical Trial to Study the Safety and Efficacy of Lurasidone in Subjects With Schizophrenia (PEARL 3 Extension Study)

Primary Outcome Measures:
  • Relapse of Psychotic Symptoms [ Time Frame: 12 Months ]

    Time to relapse will be defined as the earliest occurrence of any of the following:

    • Worsening of >= 30% positive and negative syndrome scale total score from NCT00790192 and clinical global impression-severity sub-scale >=3
    • rehospitalization for worsening of psychosis
    • emergence of suicidal ideation, homicidal ideation and/or risk of harm to self or others Comparison of time to relapse of psychotic symptoms between lurasidone and quetiapine XR after 1 year as analyzed using the Cox proportional hazard model with country as a covariate.

Secondary Outcome Measures:
  • Change From the Acute Phase Baseline to Month 6 of the Double-blind Treatment in the CogState Computerized Cognitive Scores. [ Time Frame: Baseline and 6 Months ]
    The battery has seven outcome measures that measure the cognitive constructs. The seven domains are: detection, identification, one back task, international shopping list task, one card learning task, Groton maze learning task and social emotional matching. The standardized scores for each subject at each assessment will then be averaged to yield a composite score. There are no maximum or minimum values, however a higher score indicates improved performance on the cognitive constructs. The change score is change from baseline to month 6.

  • Change From the Acute Phase Baseline to the End (Month 12) of the Double-blind Treatment in the Positive and Negative Syndrome Scale (PANSS) [ Time Frame: Baseline and 12 months ]
    The PANSS is an interview-based measure of psychopathology severity in adults with psychotic disorders. Thirty items are rated using a Likert scale, from 1 - 7. The PANSS total score is the sum of thirty items ranging from 30 to 210 (higher score representing a worsening in psychosis).

  • Change From the Acute Phase Baseline to the End (Month 12) of the Double-blind Treatment in the Clinical Global Impression Severity Scale (CGI-S) Scores [ Time Frame: Baseline and 12 months ]
    The CGI-S is a clinician-rated assessment of the subject's current illness state on a scale ranging from 1-7, where a higher score is associated with greater illness severity.
