Trial summary

One in five people will present a major depressive episode (MDE) in their lifetime. While antidepressants (ADs) are currently the standard treatment for MDE, the first AD prescribed is effective in less than 40% of patients and a complete clinical response is only observed after several weeks.

About this study

One in five people will present a major depressive episode (MDE) in their lifetime. While antidepressants (ADs) are currently the standard treatment for MDE, the first AD prescribed is effective in less than 40% of patients and a complete clinical response is only observed after several weeks. Identifying early biomarkers of the response to treatment with an AD could allow the clinician to rapidly identify patients in whom treatment will not be effective and therefore modify patient care. We have recently shown that the messenger RNA (mRNA) of two proteins, ELK1 and GPR56, were present in different amounts in the blood cells of "responder" compared to those of "non-respondent" patients. In this context, our main objective will be to determine whether ELK1 and GPR56 mRNAs, are very early biomarkers of the response to AD, i.e., biomarkers whose variation precedes the clinical response by several weeks. Secondary objectives will be to identify early phase changes in neurophysiological measures, cognitive and behavioral tasks, as well as levels of blood coding and non-coding RNAs, serum cytokine, mitochondrial and metabolic markers, neuroimaging markers as biomarkers of differential treatment outcomes to antidepressant treatment.

Patients will be treated with SERTRALINE or FLUOXETINE or DULOXETINE or MAPROTILINE (in monotherapy) with or without adjunct benzodiazepine.

Patients are identified as responders or non-responders based on their clinical assessment at 8 weeks after treatment onset.

In addition, a second stage will collect data to address another important issue for the management of patients with a MDE: to discriminate those with a major depressive disorder (MDD) from those with a bipolar disorder (BD). BD diagnosis is one of the most common reasons of failure to response to ADs. Therefore, one of our secondary objectives will be to identify biomarkers to differentiate between these two categories of patients. To do this, we will follow patients for a period of 24 months to identify those who will present during this follow-up the diagnostic criteria of bipolarity.

What is being measured

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

  1. Predictive value for antidepressant response of ELK1 mRNA levels or changes 3 days after AD start

    The area under the curve (AUC) value determined by receiving operating characteristic (ROC) analysis of ELK1 mRNA levels for the evolution of psychiatric symptoms following AD start, during a 8-weeks follow-up. Patients are identified as responders or nonresponders based on their clinical assessment

    Measured: 8 weeks of treatment

Secondary outcomes (5)
  1. Predictive value for antidepressant response of GPR56 and ELK1 mRNA levels at baseline, 3 days, 2 weeks or 8 weeks after AD start

    The area under the curve (AUC) value determined by receiving operating characteristic (ROC) analysis of GPR56 and ELK1 ELISA tests from whole blood for the evolution of psychiatric symptoms following AD start, during a 8-weeks follow-up. Patients are identified as responders or nonresponders based on their clinical assessment

    Measured: 8 weeks of treatment

  2. Predictive value for antidepressant response of coding and non-coding (micro, circular, long non coding) RNA blood levels at baseline, 3 days, 2 weeks or 8 weeks after AD start

    The area under the curve (AUC) value determined by receiving operating characteristic (ROC) analysis of coding and non-coding (micro, circular, long non coding) blood RNA levels for the evolution of psychiatric symptoms following AD start, during a 8-weeks follow-up. Patients are identified as responders or nonresponders based on their clinical assessment

    Measured: 8 weeks of treatment

  3. Predictive value for antidepressant response of serum cytokine concentration measured by immunoassay at baseline, 3 days, 2 weeks or 8 weeks, after AD start

    The area under the curve (AUC) value determined by receiving operating characteristic (ROC) analysis of serum cytokine concentration measured by immunoassay for the evolution of psychiatric symptoms following AD start, during a 8-weeks follow-up. Patients are identified as responders or nonresponders based on their clinical assessment

    Measured: 8 weeks of treatment

  4. Predictive value for antidepressant response of peripheral mitochondrial markers at baseline, 3 days 2 weeks or 8 weeks, after AD start Time Frame: 8 weeks of treatment

    The area under the curve (AUC) value determined by receiving operating characteristic (ROC) analysis of peripheral mitochondrial markers for the evolution of psychiatric symptoms following AD start, during a 8-weeks follow-up. Patients are identified as responders or nonresponders based on their clinical assessment

    Measured: 8 weeks of treatment

  5. Predictive value for antidepressant response of MRI features

    The area under the curve (AUC) value determined by receiving operating characteristic (ROC) analysis of MRI analysis for the evolution of psychiatric symptoms following AD start, during a 8-weeks follow-up. Patients are identified as responders or nonresponders based on their clinical assessment

    Measured: 8 weeks of treatment

Model description
Stratification on two groups of patients subsequently identified as responders or non-responders, after 8 weeks of treatment. Patients will be classified as responders or non-responders on the basis of the evolution of the MADRS depression scale score, i.e. an improvement of more than 50% in the intensity of symptoms between the beginning of the treatments and 8 weeks afterwards.

Questions about this trial

What is this clinical trial studying?

A study testing Blood sampling in people with Depression, Bipolar and Major Depressive Disorder, run by Assistance Publique Hopitaux De Marseille.

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 8 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: status not confirmed, as of the sponsor's last update on 6 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Raoul BELZEAUX, MD (04 91 74 46 46 ext. 33, raoul.belzeaux@ap-hm.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive value for antidepressant response of ELK1 mRNA levels or changes 3 days after AD start (time frame: 8 weeks of treatment). 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 6 Oct 2022.
