  • The safety of olanzapine plus fluoxetine in combination, plus and any side effects that might be associated with the combination.
  • The effectiveness of olanzapine plus fluoxetine compared to olanzapine and fluoxetine alone.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. To assess the efficacy of up to 8 weeks of treatment with OFC versus olanzapine and fluoxetine monotherapies, in patients with recurrent MDD without psychotic features
  2. who meet study criteria for TRD, as measured by last observation carried forward (LOCF) mean change from baseline to endpoint in the MADRS total score
  3. Treatment-resistant depression will be defined as:historic failure to achieve satisfactory response to an antidepressant (other than fluoxetine) during the current MDD episode
  4. when treated with an acceptable antidepressant drug and dose for at least 6 weeks
  5. prospective failure to achieve a satisfactory response to fluoxetine monotherapy during the 8 week study lead-in phase

Secondary Outcome Measures :
  1. To compare the efficacy, safety, and quality of life results of up to 8 weeks of OFC therapy(treatment phase) with fluoxetine and olanzapine monotherapies using the following assessments:
  2. Onset of action as measured by time to achieve and initial response (greater than or equal to 25% reduction from baseline in MADRS total score
  3. Efficacy in the treatment of co-morbid anxiety symptoms as measured by LOCF mean change from baseline to endpoint in Hamilton Psychiatric Rating Scale for Anxiety (HAM-A)total score
  4. Study-defined response and remission rates including time to achieve a full response (defined as greater than or equal to 50% reduction in MADRS total score)
  5. and time to achieve remission (defined as MADRS total score less than or equal to 10 at endpoint)
  6. LOCF mean change from baseline to endpoint in Clinical Global Impression - Severity of Depression score
  7. (CGI-Severity of Depression), individual MADRS questions,and HAM-A item scores
  8. Repeated measures analyses of post-baseline MADRS and HAM-A total scores
  9. The incidence and severity of treatment-emergent adverse events and EPS. The Barnes Akathisia Scale,Simpson-Angus Scale, and the Abnormal Involuntary Movement Scale (AIMS) will be used to assess EPS
  10. The Brief Psychiatric Rating Scale (BPRS) to evaluate the emergence of psychosis
  11. Changes in vital signs and weight, laboratory analytes, and electrocardiograms (ECG)),Quality of life as measured by the LOCF mean change from baseline to endpoint on the Sheehan Disability Scale (SDS) score and the Short Form 36 Health Survey
  12. Additional secondary objectives are to assess the efficacy, safety, and quality of life results of up to 8 additional weeks of open-label OFC therapy (after the treatment phase)using the following measures:
  13. LOCF mean change from baseline to endpoint in MADRS, HAM-A, and CGI-Severity of Depression scores and study-defined rates of response and remission
  14. Safety as measured by the incidence and severity of treatment-emergent adverse events, and EPS using the Barnes Akithisia Scale, Simpson Angus Scale and the AIM
  15. The BPRS to examine the emergence of psychosis
  16. Changes in vital signs and weight, laboratory analytes, and ECG
