NCT00958568

Brief Summary

The purpose of this study is to determine whether olanzapine and fluoxetine combination (OFC) if used for a long time (47 weeks) makes patients suffering from Treatment Resistant Depression stable, determine if OFC is safe when used to treat patients with Treatment Resistant Depression for a long time (up to 47 weeks), to determine whether olanzapine and fluoxetine combination or fluoxetine alone is better to treat Treatment Resistant Depression when treated for a long time (up to 47 weeks) and to assess the quality of life during treatment.

Outcome Measures

Primary Outcomes (1)

  • Time to Relapse by Any Criteria

    Relapse defined as meeting any of these criteria: 50% increase in Montgomery-Asberg Depression Rating Scale (MADRS) score from randomization with a Clinical Global Impressions-Severity (CGI-S) of Depression score increase to a score of 4 or more; Hospitalized for depression or suicidality; Discontinued due to lack of efficacy/worsening of depression/suicidality. MADRS is a 10-item rating scale for depressive mood symptoms severity, items rated on 0-6 scale, with total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms). CGI-S measures severity of illness at time of assessment compared with start of treatment. Scores range from 1 (normal, not at all ill) to 7 (the most extremely ill). Lack of Efficacy/Worsening of depression was at discretion of investigator based on clinical observation. Suicidality is thoughts or actions of self-harm as determined by the investigator. Those who did not relapse were "censored" at their last observation.
