The purpose of this study is to explore the impact of ziprasidone on the distribution of metabolic syndrome risk factors in a population of patients presenting with glucose intolerance, dyslipidemia and/or elevated waist circumference associated with their current antipsychotic medication.
The trial was terminated prematurely on May 24, 2012, due to changes in organizational strategy and resources. The decision to terminate the trial was not based on any safety or efficacy concerns.
