ClinicalTrials.gov Identifier:	NCT00958568

Purpose

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.

Arms	Assigned Interventions
Olanzapine and Fluoxetine combination: Experimental	Drug: Olanzapine and Fluoxetine combination Open label acute phase: introductory dose for 4 days then 3/25, 6/25, 12/25, 6/50, 12/50 or 18/50mg, oral, daily, for 6-8 weeks. Open label stabilization phase: 6/25, 12/25, 6/50, 12/50 or 18/50 mg, oral, daily for 16-20 weeks. Double blind relapse prevention phase: dose determined during stabilization phase at week 17, oral, daily, for 27 weeks.
Fluoxetine: Active Comparator	Drug: Fluoxetine 25 or 50mg/day fixed dosing for 27 weeks

Detailed Description:

This is a multicenter, randomized, double-blind, active comparator-controlled, parallel study of patients with Treatment Resistant Depression (TRD), comparing the efficacy and safety of olanzapine and fluoxetine Combination (OFC) versus fluoxetine in relapse prevention of stabilized patients with TRD. The study will consist of 4 phases: a screening phase; a 6- to 8-week open-label acute treatment phase; a 10- to 12-week open-label stabilization phase; and a 27- to 29-week double-blind relapse prevention treatment phase. Patients who demonstrate response to open-label OFC during the acute treatment phase will continue into the stabilization phase. Patients who remain stable while receiving open-label OFC during this phase will be randomized to receive either OFC or fluoxetine during the double-blind relapse prevention phase. Investigators and patients will be blinded to the precise duration of the stabilization period, the definition of remission, and the criteria for entry into the relapse prevention phase; this information is described in a supplement given to Ethical Review Boards (ERBs) and regulatory authorities.
