Long-term Extension Study of SM-13496 (Lurasidone HCl) in Patients With Schizophrenia

The PANSS is an interview-based measure of the severity of psychopathology in adults with psychotic disorders. The measure is comprised of 30 items and three subscales: the Positive subscale contains seven questions to assess delusions, conceptual disorganization, hallucinations behavior, excitement, grandiosity, suspiciousness/persecution, and hostility; the Negative subscale contains seven questions to assess blunted effect, emotional withdrawal, poor rapport, passive/apathetic social withdrawal, lack of motivation, and similar symptoms; and the General Psychopathology subscale addresses other symptoms such as anxiety, somatic concern, and disorientation. An anchored Likert scale from 1-7, where values of 2 and above indicate the presence of progressively more severe symptoms, is used to score each item. The PANSS total score is the sum of all 30 items and ranges from 30 through 210. A higher score is associated with greater illness severity.

Time frame: DB baseline and up to 32 weeks (LOCF endpoint)

Population: ITT (intent-to-treat) population

The PANSS is comprised of 30 items and three subscales. The General Psychopathology subscale addresses other 16 symptoms such as anxiety, somatic concern, and disorientation. An anchored Likert scale from 1-7, where values of 2 and above indicate the presence of progressively more severe symptoms, is used to score each item. The PANSS General Psychopathology subscale score is the sum of all 16 items and ranges from 16 through 112. A higher score is associated with greater illness severity.

Time frame: DB baseline and up to 32 weeks (LOCF endpoint)

Population: ITT (intent-to-treat) population

The PANSS is comprised of 30 items and three subscales. The Negative subscale contains seven questions to assess blunted effect, emotional withdrawal, poor rapport, passive/apathetic social withdrawal, lack of motivation, and similar symptoms. An anchored Likert scale from 1-7, where values of 2 and above indicate the presence of progressively more severe symptoms, is used to score each item. The PANSS Negative subscale score is the sum of all 7 items and ranges from 7 through 49. A higher score is associated with greater illness severity.

Time frame: DB baseline and up to 32 weeks (LOCF endpoint)

The Positive subscale contains seven questions to assess delusions, conceptual disorganization, hallucinations behavior, excitement, grandiosity, suspiciousness/persecution, and hostility. An anchored Likert scale from 1-7, where values of 2 and above indicate the presence of progressively more severe symptoms, is used to score each item. The PANSS Positive subscale score is the sum of all 7 items and ranges from 7 through 49. A higher score is associated with greater illness severity.

Population: ITT (intent-to-treat) population

CGI-S is a clinician-rated assessment of the participant's current disease state on a 7-point scale, where a higher score is associated with greater severity of the disease. Baseline in the prior study (D1001056, double-blind \[DB\] baseline) was defined as baseline of the prior study. Baseline in the present study (D1001057, extension \[EXT\] baseline) was defined as Week 6 in the prior study. The last post-baseline visit data collected during the study treatment of the present study were carried forward and defined as the last observation carried forward (LOCF) endpoint.

Time frame: DB baseline and up to 32 weeks (LOCF endpoint)

Population: ITT (intent-to-treat) population

Time frame: EXT baseline and up to 26 weeks

Population: Safety population defined as subjects who receive at least one dose of the study drug.

Proportion of participants with treatment-emergent adverse events. An adverse event was defined as any untoward medical occurrence in a patient treated with a medicinal (investigational) product and which did not necessarily have a causal relationship with this treatment. Treatment-emergent adverse events are defined as adverse events with a start date on or after the date of initial administration of study drug in the present study through the end of follow-up or adverse events occurring before the date of initial administration of study drug in the present study and worsening during the study treatment in the present study.

Time frame: EXT baseline and up to 26 weeks

Population: Safety population defined as subjects who receive at least one dose of the study drug.

Proportion of participants with treatment-emergent adverse events. A serious adverse event was defined as an AE that met one or more of the following criteria: Resulted in death; Was life-threatening (i.e., a patient was at immediate risk of death at the time of the event, not an event where occurrence in a more severe form might have caused death); Required hospitalization or prolongation of existing hospitalization; Resulted in persistent or significant disability or incapacity; Was a congenital anomaly or birth defect; Was an important medical event that might jeopardize the patient or might require medical intervention to prevent one of the outcomes listed above.

Time frame: EXT baseline and up to 26 weeks

Population: Safety population defined as subjects who receive at least one dose of the study drug.
