About this study

Official title: Prediction of the Therapeutic Response in Depression Based on an Early Neuro-computational Modeling Assessment of Motivation

This study aims to better understand the mechanisms of action of antidepressants, but also the neural correlates of motivation deficits. One hundred patients with a moderate to severe major depressive episode will be enrolled in this prospective multicenter study. The objective will be to predict the therapeutic response to two first-line antidepressants on the basis of an early neurocomputational assessment of motivation. Antidepressant treatment will be administered as monotherapy after randomization between two drugs: escitalopram and vortioxetine. Patients will undergo six visits and follow-up for one year. The investigators will combine computer modeling and functional MRI to identify motivational deficits and elucidate their brain correlates before initiation, after 7 days and after 6 months of treatment. 36 healthy volunteers will also be included to allow comparison with patients with depression. They will not receive any treatment.

Read the detailed description

One hundred patients with a moderate to severe major depressive episode will be enrolled in this prospective multicenter study. Six visits will be scheduled within a year:

  • V0 (inclusion visit): verification of inclusion and exclusion criteria, information, and consent.
  • V1 (before randomization - baseline state):
  • Clinical evaluation using validated questionnaires for the severity of depression, quality of life, anhedonia, apathy, and cognitive dysfunction.
  • Neuro-cognitive evaluation using a battery of tests to explore motivation, emotion processing, belief construction, and their updating. Part of the tests will be performed during the functional MRI session.
  • Structural (anatomical) and functional MRI, ASL.
  • Blood samples.
  • Randomization and introduction of the new antidepressant will occur immediately after V1. To maximize acceptability by referring psychiatrists, dosage and co-prescriptions will be at the discretion of the psychiatrist in charge, but the assigned treatment will not be changed for 4 weeks (until V3).
  • V2 (7 days after the beginning of the new antidepressant - 'early response visit'):
  • Similar to V1.
  • V3 (28 days after the beginning of the new antidepressant - 'conventional response visit'):
  • Clinical evaluation using validated questionnaires for the severity of depression, quality of life, anhedonia, apathy, and cognitive dysfunction.
  • Blood samples
  • V4 (6 months after the beginning of the new antidepressant - 'remission visit'):
  • Clinical evaluation using validated questionnaires for the severity of depression, quality of life, anhedonia, apathy, and cognitive dysfunction.
  • Cognitive evaluation using a battery of tests to explore motivation, emotion processing, belief construction, and their updating.
  • Structural (anatomical) MRI, ASL
  • Blood samples
  • V5 (one year after the beginning of the new antidepressant - 'functional remission visit'):
  • Clinical evaluation using validated questionnaires for the severity of depression, quality of life, anhedonia, apathy, and cognitive dysfunction. 36 healthy volunteers without a history of neurologic or psychiatric disorder, matched for age, gender, and education will be included. They will perform V0-V2 (without MRI and blood sample at V2). Healthy volunteers will not receive any treatment as part of the research.

What participants receive

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

  • escitalopramOther

    Patients will receive an antidepressant strategy : escitalopram. The strategy will not be modified for a period of 4 weeks. Dosage adjustment and co-prescriptions will be at the discretion of the refeering psychiatrist. After 4 weeks, the strategy can be adapted by the refeering psychiatrist exactly as if the patient had not been included in the trial.

  • vortioxetineOther

    Patients will receive an antidepressant strategy : vortioxetine. The strategy will not be modified for a period of 4 weeks. Dosage adjustment and co-prescriptions will be at the discretion of the refeering psychiatrist. After 4 weeks, the treatment strategy can be adapted by the refeering psychiatrist exactly as if the patient had not been included in the trial.

What is being measured

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

  1. Prediction of the therapeutic response (MADRS score) 28 days after the introduction of the antidepressant strategy (V3) based on the early changes (differences between V1 and V2) of the computational phenotype of depressed patients.

    The therapeutic response will be measured with the Montgomery-Asberg Depression Rating Scale (MADRS). The MADRS is a 10- item scale widely used in depression research to assess the severity of depression. Response will be defined by a score divided by 2 compared to baseline MADRS score, while remission will be defined by a score < 7 (symptom absent) 28 days after the initiation of the antidepressant strategy.

    The "computational phenotype" is the outcome of the computationnal analysis of behavior. It is expressed in abstract unit. The change in computationnal phenotype between V1 and V2 will be entered in logistic regression aiming to predict clinical response at 28 days, measured with the MADRS score.

    Measured: Baseline state (before the start of antidepressant strategy), V2 (after 7 days of antidepressant) and V3 (after 28 days of antidepressant)

Model description
Randomization and introduction of the new antidepressant will occur immediately after V1. Patients will receive an antidepressant as monotherapy after randomization between two strategies: escitalopram and vortioxetine. To maximize acceptability by referring psychiatrists, dosage and co-prescriptions will be at the discretion of the psychiatrist in charge, but the allocated treatment will not be changed for 4 weeks (until V3).

Questions about this trial

What is this clinical trial studying?

A study testing escitalopram and vortioxetine in people with Major Depressive Disorder, run by Centre Hospitalier St Anne at 5 sites in France.

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 6 inclusion and 12 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: looking for participants now, as of the sponsor's last update on 10 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in France. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Fabien Vinckier (0033683714083, f.vinckier@ghu-paris.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prediction of the therapeutic response (MADRS score) 28 days after the introduction of the antidepressant strategy (V3) based on the early changes (differences between V1 and V2) of the computational phenotype of depressed patients. (time frame: Baseline state (before the start of antidepressant strategy), V2 (after 7 days of antidepressant) and V3 (after 28 days of antidepressant)). 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 NCT05866575, which also lists 57 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 10 Jul 2024.
