Study Description
Brief Summary:

This is a study on the effectiveness, tolerability and safety of oral ziprasidone as monotherapy in patients with major depressive disorder (MDD). Outpatients suffering from MDD will be treated with either ziprasidone or placebo for 12 weeks.

Hypothesis: There will be a statistically significant difference in the magnitude of response, as measured by a decrease in baseline 17-item Hamilton Depression Rating Scale (HAM-D-17) scores, between the two treatment groups; the reduction in HAM-D-17 scores will be greater in the ziprasidone monotherapy group than in the placebo group.

Condition or disease Intervention/treatment Phase
Major Depressive Disorder Drug: Ziprasidone Drug: Placebo Phase 2

Detailed Description:

Exploratory hypothesis 1: There will be a statistically significant difference in the percentage of responders in the two treatment groups; response rates will be significantly higher for the ziprasidone monotherapy compared to the placebo group.

Exploratory hypothesis 2: The change in 6-VAS-D scores during the trial will be highly correlated to the change in HAM-D-17 and QIDS-SR during the trial.

Arms and Interventions

Arm Intervention/treatment
Active Comparator: 1
Patients in group 1 will receive Ziprasidone for the full 12 weeks of the study.
Drug: Ziprasidone
20mg-80mg a day. Dose increases of 20mg per day may occur at three study visits as directed by clinician. Maximum; 80mg per day per patient.
Other Name: Geodon
Active Comparator: 2
Patients in Group 2 will receive placebo for the first 6 weeks of the study, then will receive Ziprasidone for the last 6 weeks.
Drug: Ziprasidone
20mg-80mg a day. Dose increases of 20mg per day may occur at three study visits as directed by clinician. Maximum; 80mg per day per patient.
Other Name: Geodon
Placebo Comparator: 3
Patients in Group 3 will receive placebo for the full 12 weeks of the study.
Drug: Placebo
0mg Placebo per day. "Dose increases" and "dose decreases" may occur, but patient will remain at 0mg placebo

Outcome Measures

Primary Outcome Measures :
  1. Hamilton Depression Rating Scale (HAM-D-17) Scores [ Time Frame: 6 weeks ]
    Higher numbers represent more symptoms of a major depressive episode. Minimum is 0. Maximum is 52.

Secondary Outcome Measures :
  1. Responder/Non-responder [ Time Frame: 6 weeks ]
    A responder during phase 1 or phase 2 is someone who demonstrated a 50% or greater decrease in HAMD-17 scores during phase 1 or phase 2 (corresponding).

  2. Change in 6-VAS-D Scores During Each Phase. [ Time Frame: 6 weeks ]
