Official title

A Three-phase Study Designed to Test the Efficacy, Tolerability and Safety of the Combination of Ziprasidone With Selective Serotonin Reuptake Inhibitors (SSRI) for Patients With Major Depressive Disorder (MDD) That do Not Sufficiently Respond to Treatment With SSRIs.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to see if adding the study drug, ziprasidone, to an antidepressant medication helps improve symptoms of Major Depressive Disorder (MDD). We are studying the drug's effectiveness in treating depression, as well as its safety when it is added to another drug. Hypothesis A: There will be a difference in the percentage of responders in the two treatment conditions during phase 2; response rates will be higher for the ziprasidone group.
