  Purpose

This study is a ten-week, placebo-controlled, double-blind, cross-over, randomized trial of the novel antipsychotic agent, aripiprazole, added to 20 obese stable olanzapine-treated patients with schizophrenia or schizoaffective disorder. The advantage of the crossover design is that each subject will act as their own control and fewer subjects will be required than a between-group design.

Primary Outcome Measures:
  • Change From Baseline in Weight (Lbs) [ Time Frame: baseline, week 4 ] [ Designated as safety issue: No ]
    Evaluating change in weight (lbs) between Baseline and Week 4, comparing subjects treated with aripiprazole for 4 weeks to subjects treated with placebo for 4 weeks.

  • Change From Baseline in Body Mass Index (BMI) [ Time Frame: baseline, week 4 ] [ Designated as safety issue: No ]
    Evaluating change in Body Mass Index (BMI) between Baseline and Week 4, comparing subjects treated with aripiprazole for 4 weeks to subjects treated with placebo for 4 weeks.

  • Change From Baseline in Waist-hip Ratio (WHR) [ Time Frame: baseline, week 4 ] [ Designated as safety issue: No ]
    Evaluating change in waist-hip ratio (WHR) between Baseline and Week 4, comparing subjects treated with aripiprazole for 4 weeks to subjects treated with placebo for 4 weeks.

  • Change From Baseline in Fasting Total Cholesterol [ Time Frame: baseline, week 4 ] [ Designated as safety issue: No ]
    Evaluating change in fasting total cholesterol between Baseline and Week 4, comparing subjects treated with aripiprazole for 4 weeks to subjects treated with placebo for 4 weeks.

  • Change From Baseline in Low-density Lipoprotein (LDL) [ Time Frame: baseline, week 4 ] [ Designated as safety issue: No ]
    Evaluating change in low-density lipoprotein (LDL) between Baseline and Week 4, comparing subjects treated with aripiprazole for 4 weeks to subjects treated with placebo for 4 weeks.

  • Change From Baseline in High-density Lipoprotein Cholesterol (HDL-C) [ Time Frame: baseline, week 4 ] [ Designated as safety issue: No ]
    Evaluating change in high-density lipoprotein cholesterol (HDL-C) between Baseline and Week 4, comparing subjects treated with aripiprazole for 4 weeks to subjects treated with placebo for 4 weeks.

  • Change From Baseline in Triglycerides [ Time Frame: baseline, week 4 ] [ Designated as safety issue: No ]
    Evaluating change in triglyceride levels between Baseline and Week 4, comparing subjects treated with aripiprazole for 4 weeks to subjects treated with placebo for 4 weeks.
