About this study

The aim of this pharmaco-MRI study is to investigate neural correlates of variable antidepressant treatment response driven by genetic variation in multiple genes involved in depression.

Thirty Major Depressive Disorder (MDD) patients with a concurrent major depressive episode will undergo three MRI scanning sessions after escitalopram treatment initiation. Furthermore, extensive behavioral assessments and measures of potential peripheral markers such lymphocyte mRNA or pharmacological parameters on platelets or lymphocytes will be performed.

Imaging measures have been suggested to be superior for drug response assessment as compared to psychometric scales, which hardly correlate with biological parameters. Since imaging techniques are too expensive and sophisticated for a broad clinical use, this study will provide pilot data on potential peripheral biomarkers of neural activation being related to drug response.

The aim of this pharmaco-MRI study is to investigate neural correlates of variable antidepressant treatment response driven by genetic variation in multiple genes involved in depression.

Thirty Major Depressive Disorder (MDD) patients with a concurrent major depressive episode will undergo three MRI scanning sessions at baseline, 4 hours and 8 weeks after escitalopram treatment initiation. During each MRI session, one structural and 3 fMRI scans each engaging different brain circuitries will be performed. All subjects will undergo extensive behavioral assessment and will be genotyped. Furthermore, potential peripheral markers such lymphocyte mRNA or pharmacological parameters on platelets or lymphocytes will be assessed.

The investigators expect that genetic variants which have been associated with variable response to SSRIs in previous Imaging Genetics studies are modulating neural targets of drug response. Moreover, peripheral markers are expected to correlate with these brain region measurements.

Imaging measures have been suggested to be superior for drug response assessment as compared to psychometric scales, which hardly correlate with biological parameters. Since imaging techniques are too expensive and sophisticated for a broad clinical use, this study will provide pilot data on peripheral biomarkers of neural activation being related to drug response. Furthermore, this study will demonstrate whether and how genotypes impact on the dynamics of neural drug response in vivo.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Escitalopram in people with Depression, run by Medical University of Vienna at 1 site in Austria.

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 8 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 31 Oct 2016. 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 Austria. 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 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?

BOLD signal (time frame: 8 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 NCT01251471, 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 31 Oct 2016.
