About this study

Official title: Associations Between Gene-Polymorphisms, Endo-Phenotypes for Depression and Antidepressive Treatment (AGENDA)

The purpose of this study is to determine whether outcome following antidepressant treatment can be used as a tool to evaluate endo-phenotypes for depression.

Read the detailed description

The research in depression has for some years focused at the identification of endo-phenotypes. Endo-phenotypes are heritable biological or psychological markers, which are more commonly found in patients and their healthy relatives than in the general population.

Recent studies point at disturbed regulation of the hypothalamic-pituitary-adrenocortical (HPA) system as a possible endo-phenotype for depression.

The hypothesis of AGENDA are that endo-phenotypes are affected by treatment with antidepressants in healthy first degree relatives.

AGENDA is a four week randomized, placebo-controlled, double-blind trial in which first degree relatives of patients with the diagnosis of depression are randomised in to two groups, which are treated with either placebo or antidepressant medicine (Cipralex). We expect to include 80 healthy subjects, with the predisposition for depression, since one of their parents or siblings recently was treated for depression.

The subjects will be examined before and after four weeks of treatment by a thorough interview concerning psychiatric symptoms (SCAN), including depressive symptoms, personality, perceived stress and cognitive function. The effect of antidepressant on stress is measured with saliva-cortisol and by the response to the combined dexamethasone corticotropin-releasing (CRH) hormone test. Additionally, MR and PET scans of the 5-HT4 receptor function will be conducted before and after 4 weeks of treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Escitalopram in people with Healthy, run by University of Copenhagen at 1 site in Denmark.

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 5 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 30 Jun 2009. 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 Denmark. 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?

Changes in the response on the combined dexamethasone corticotropin-releasing hormone test before and after 4 weeks treatment with escitalopram or placebo. (time frame: 4-6 weeks). 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 NCT00386841, which also lists 3 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 30 Jun 2009.
