Primary Outcome Measures:
  • Change From Baseline in Negative Symptoms of Schizophrenia Measured by the Negative Symptom Assessment (NSA) Scale Total Score [ Time Frame: Baseline of A7501013 to Day 365 ] [ Designated as safety issue: No ]
    The NSA Scale is a 16-item clinician-rated instrument for rating the negative symptomatology of schizophrenia. Total score ranges from 16 (best) to 96 (worst), with greater scores indicating greater severity of symptoms.


Secondary Outcome Measures:
  • Change From Baseline in Quality of Life Measured by the Quality of Life Scale (QLS) Total Score [ Time Frame: Baseline of A7501013 to Day 365 ] [ Designated as safety issue: No ]
    The QLS is a 21-item clinician-rated scale for rating psychosocial functioning (Interpersonal Relations, Instrumental Role, Intrapsychic Foundations, and Common Objects and Activities). The score ranges from 0 (worst) to 126 (best), with greater values indicating better quality of life.
