About this study

Official title: Combined Use of Intranasal Oxytocin and Interpersonal Psychotherapy for the Treatment of Major Depressive Disorder (MDD): A Randomized Controlled Trial

This study evaluates the addition of intranasal oxytocin to the treatment of Major Depression using interpersonal psychotherapy. Half of the participants will receive a placebo adjunct to interpersonal psychotherapy, and the other half will receive oxytocin.

Read the detailed description

Depression is a debilitating mental health condition that carries great consequences for both the individual and society. Crucially, at least one third of depressed patients do not respond to existing interventions and relapse rates are high, alerting scientists to the need to explore possible adjunctive treatments and novel therapeutic targets. In this regard, research on the use of oxytocin in the treatment of depression is promising.

It is well documented that interpersonal stress predicts the onset of depression, and that social isolation is a symptom of psychological distress that can leave patients with a poor prognosis for recovery. Therapeutic interventions focused on the alleviation of social conflict and strengthening of social bonds (i.e. Interpersonal Psychotherapy; IPT) show greater efficacy for the treatment of depression than other psychological interventions (NIMH Treatment of Depression Collaborative Research Program; Elkin et al. 1984). It has been posited that oxytocin, a naturally produced hormone that is involved in social-support seeking and stress-regulation, could represent a biological link between social stress and depression in adulthood. The salubrious effect of exogenous oxytocin on human social behavior is well documented: Oxytocin has been shown to make individuals feel more securely attached in their social relationships, increase their trust in others and openness to new ideas, improve their recall of specific and positive social autobiographical memories, and improve social learning. Importantly, these factors have been shown to improve the efficacy of Interpersonal Psychotherapy. Thus, It stands to reason that the use of oxytocin as an adjunct to IPT could improve its efficacy for the treatment of depression, which is an important prospect when considering that a third of patients do not respond to existing therapies.

In the proposed research project, we will conduct a Randomized Controlled Trial for the treatment of Major Depression with IPT and adjunctive oxytocin. Patients will be screened for eligibility, undergo structured psychotherapy for twelve weeks, and will be followed longitudinally for changes in quality of social functioning, interpersonal stress, psychiatric symptoms and depressive relapse. Establishing novel interventions for depression could position healthcare providers to better alleviate the burden and personal suffering caused by this disorder.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study of Depressive Disorder, run by Concordia University, Montreal at 1 site 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 27 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Diagnostic status: Major Depressive Episode Using The SCID-IV [Change Score] (time frame: Baseline, 4 months later (following therapy)). The study lists 10 primary outcomes in all. 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 NCT02405715, which also lists 1 linked publication.

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 27 Jul 2021.
