About this study

Official title: A Study to Assess the Long-Term Efficacy and Safety of Olanzapine and Fluoxetine Combination Versus Fluoxetine Only in the Relapse Prevention of Stabilized Patients With Treatment-Resistant Depression

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.

Read the detailed description

This is a multicenter, randomized, double-blind, active comparator-controlled, parallel study of participants with Treatment Resistant Depression (TRD), comparing the efficacy and safety of olanzapine and fluoxetine Combination (OFC) versus fluoxetine in relapse prevention of stabilized participants 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. Participants who demonstrate response to open-label OFC during the acute treatment phase will continue into the stabilization phase. Participants 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 participants 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Olanzapine and Fluoxetine combination (OFC) and Fluoxetine in people with Treatment Resistant Depression, run by Eli Lilly and Company at 66 sites in 8 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 66 sites in United States, India, Turkey (Türkiye), Argentina, Russia and 3 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Apr 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to Relapse by Any Criteria (time frame: Randomization (Week 20) to Week 47). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00958568.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2014.
