Detaljeret beskrivelse
The primary objective of this study was to test the hypothesis that 1 or more dose levels of LY2140023 given orally to patients with schizophrenia twice daily for 4 weeks would demonstrate significantly greater efficacy than placebo. Efficacy was defined as clinical response measured by the Positive and Negative Syndrome Scale (PANSS) total score as assessed at 4 weeks.
This was a multi-center, randomized, double-blind, parallel, placebo- and active comparator-controlled trial with 4 study periods. Approximately 870 patients who met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV, APA 2000) criteria for schizophrenia as defined by the modified Structured Clinical Interview for DSM-IV Diagnosis (SCID) were to be entered into the study so that approximately 550 patients would be considered evaluable (that is, randomized patients with a baseline and at least 1 postbaseline PANSS total score following study treatment). Male and female patients aged 18 to 65 years who qualified for enrollment into the study were randomized in a 2:2:2:2:2:1 ratio to receive 5 mg, 20 mg, 40 mg, or 80 mg twice daily LY2140023, placebo twice daily, or placebo once each morning and 15 mg olanzapine once each evening for approximately 28 days.
