Brief Summary:
This is a randomized, double-blind study to determine how well intramuscular (IM) olanzapine depot works compared to oral olanzapine; evaluate the safety and tolerability of IM olanzapine depot compared to oral olanzapine; evaluate different doses of IM olanzapine depot; and determine the blood levels of IM olanzapine depot in patients at different points in time after an injection.

Primary Outcome Measures :
  1. Determine comparative efficacy in patients with schizophrenia of non-inferiority of IM olanzapine depot high and low doses versus oral olanzapine based on exacerbation rates after 6 months of maintenance treatment
  2. Determine comparative efficacy in patients with schizophrenia of superiority of IM olanzapine depot low, med and high doses versus very low dose based on time to exacerbation of symptoms of schizophrenia

Secondary Outcome Measures :
  1. Demonstrate non-inferior efficacy in terms of exacerbation rates of high plus low dose IM olanzapine depot versus medium dose
  2. Provide information on transition of patients stabilized on oral olanzapine 10, 15 or 20 mg/day to therapeutic doses of IM olanzapine depot
  3. Demonstrate superiority of high dose, medium dose and low dose IM olanzapine depot compared with very low dose IM olanzapine depot in change from baseline to endpoint in PANSS total, positive, negative and general subscales
  4. Assess the safety and tolerability of high plus low dose IM olanzapine depot versus oral olanzapine
  5. Assess the safety and tolerability of medium dose IM olanzapine depot versus oral olanzapine
  6. Assess the safety and tolerability of each IM olanzapine depot treatment group versus very low dose IM olanzapine depot
  7. Compare the efficacy of high plus low dose IM olanzapine depot versus oral olanzapine during maintenance treatment on quality of life, drug attitude inventory, resource utilization and hospitalization measures
  8. Compare the efficacy of high, medium and low doses of IM olanzapine depot during maintenance treatment on quality of life, drug attitude inventory, resource utilization and hospitalization measures
  9. Characterize the pharmacokinetics of olanzapine following multiple dosing with IM olanzapine depot at each of the prescribed dosing regimens and to compare IM olanzapine depot pharmacokinetics with oral olanzapine pharmacokinetics
