Phase 3
Completed
Conditions
Schizophrenic Disorders
Registration Number
NCT00088491
Lead Sponsor
Eli Lilly and Company
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
NameTimeMethod
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
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
NameTimeMethod
Demonstrate non-inferior efficacy in terms of exacerbation rates of high plus low dose IM olanzapine depot versus medium dose
Provide information on transition of patients stabilized on oral olanzapine 10, 15 or 20 mg/day to therapeutic doses of IM olanzapine depot
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
Assess the safety and tolerability of high plus low dose IM olanzapine depot versus oral olanzapine
Assess the safety and tolerability of medium dose IM olanzapine depot versus oral olanzapine
Assess the safety and tolerability of each IM olanzapine depot treatment group versus very low dose IM olanzapine depot
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
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
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
