About this study

This nationwide study will create a DNA collection to permit qualified scientists to search for depression-related genes.

More than 750 families with at least two siblings who have experienced major depression are needed for the study. Participants will be interviewed about psychiatric and family history, and will be asked to provide a small blood specimen. The identification of predisposing genes can lead to greater understanding of the brain mechanisms involved in severe depression which can in turn lead to the discovery of new treatments.

A Certificate of Confidentiality from the federal government ensures that all information will be strictly confidential. Blood specimens are identified only by code number (not by name).

Reimbursement is provided.

Read the detailed description

Studies of patterns of major depression in families suggest that 50 to 70% of the predisposition to major depression is caused by genes. People with recurrent depression and earlier ages of onset have more relatives with depression. There are probably at least several interacting genes, rather than a single gene as in some disorders. The identification of predisposing genes is likely to lead to greater understanding of the brain mechanisms involved in severe depression. This could lead to the discovery of new treatments.

This study will create a DNA collection to permit qualified scientists to search for depression-related genes. More than 750 families with at least two siblings who have experienced major depression are needed for the study.

Participants in this study will be interviewed about psychiatric and family history, and will be asked for a small blood specimen. Interviews can be conducted in person or by telephone. For telephone interviews, blood sample collection will be arranged at a location and time convenient for the participant. Participants will also be asked for help in inviting other family members to participate. No family member will be contacted without the permission and assistance of another participating family member.

What participants receive

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

Study groups in NCT00005914
Study groupRoleWhat they receive
Probands and family membersIndividuals with major depressive disorder who meet study criteria, and members of their families. No intervention. This is a genetic study only.

What is being measured

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

  1. Major depressive disorder

    Participants will attend an interview regarding personal and family history of psychiatric disorders, and give a blood specimen. Genotypes from blood samples will be studied for genetic linkage (within families) with the presence of major depressive disorder.

    Measured: One patient interview session (typically 2 hours), and blood draw (10-20 minutes)

Questions about this trial

What is this clinical trial studying?

An observational study of Depression, run by Stanford University at 6 sites in United States.

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 3 inclusion and 1 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 19 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. 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.

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?

Major depressive disorder (time frame: One patient interview session (typically 2 hours), and blood draw (10-20 minutes)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 Apr 2019.
