About this study

Official title: Prevention of Relapse in Recurrent Depression With MBCT

This study will determine the effectiveness of mindfulness-based cognitive therapy (MBCT) in preventing depression relapse.

Read the detailed description

Depression is a serious condition that can cause significant social and emotional problems and reduce the overall quality of life. Relapses in depressive episodes are common and may result in a patient's reluctance to follow a treatment regimen, thus making the episode more severe. Safe and effective therapies to prevent depression relapse are needed. This study will compare three different approaches to determine which is most effective in preventing relapses in depressive episodes.

This study will comprise 2 parts. In Part 1, all participants will receive antidepressant medication for 6 months. Participants whose depression symptoms do not improve will complete their study participation at the end of Part 1. Participants who respond to their regimen will be enrolled in Part 2. This part will last 18 months. During Part 2, participants will be randomly assigned to one of three groups. Participants in Group 1 will continue the drug regimen they began in Part 1. Participants in Group 2 will discontinue their antidepressants and attend an 8-week relapse prevention program. This MBCT program is designed to help participants learn skills that can increase their awareness and change their reaction to stressful events. Participants in Group 3 will have their antidepressant medication from Phase 1 switched to a placebo without their knowledge. Self-report scales will be used to assess the depressive symptoms of participants at the beginning of the study, at the end of Phase 1, and at the end of the study, after Phase 2.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Mindfulness based cognitive therapy (MBCT)Behavioural

    Also called MBCT

    Following antidepressant discontinuation, participants receive MBCT, an 8-week group program that integrates aspects of cognitive therapy and mindfulness meditation.

  • AntidepressantsDrug

    Also called Antidepressant medication

    Participants continue on dosage of the antidepressant that was used to achieve clinical remission.

  • Placebo plus clinical managementDrug

    Also called Placebo and Clinical Management

    Following discontinuation of active antidepressant, participants are placed onto the placebo and clinical management regimen.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Mindfulness based cognitive therapy (MBCT) and Antidepressants in people with Depression, run by Centre for Addiction and Mental Health at 2 sites in Canada.

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 1 inclusion and 10 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 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Relapse of depression (time frame: Measured at Month 18). 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 NCT00183560, which also lists 6 linked publications.

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 Jul 2015.
