About this study

Official title: Prediction of the Response to a Course of Transcranial Magnetic Stimulation (rTMS) Based on the Acute Variation in Heart Rate Variability Obtained After a Single RTMS Session in Patients with Major Depressive Disorder

Changes in heart rate variability following a single session of rTMS will be tested as a predictor of response to a course of 30 rTMS sessions in patients with major depressive disorder (MDD).

Read the detailed description

The objective of this study is to investigate whether acute changes in heart rate variability following a single session of repetitive transcranial magnetic stimulation (rTMS) can predict the response to a 30-session course of rTMS in patients with major depressive disorder (MDD) with good sensitivity and specificity. Patients who are prescribed rTMS to treat an episode of MDD at one of the nine participating centres will be invited to participate in the study. The protocol includes one inclusion visit and seven evaluation visits before, during, and after the course of rTMS. The rTMS course will last for six weeks, comprising of 30 sessions with five sessions per week. Prior to the start of the rTMS course, the patient will have to fill in a number of questionnaires. Before the first session, heart rate variability will be assessed by recording the RR interval at rest using a heart rate belt on the armchair stimulation. A second RR interval recording will be taken immediately after the first rTMS session. Patients will answer questionnaires weekly and after the final rTMS session to track the progression of depressive symptoms.

What participants receive

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

  • repetitive transcranial magnetic stimulationDevice

    rTMS will be applied 5 days out of 7 for 6 weeks, for a total of 30 sessions. The area stimulated will be the left dorsolateral prefrontal cortex, at a frequency of 10 Hz, at 110% of motor threshold for approximately 20 minutes (i.e. 3,000 stimulations per session).

What is being measured

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

  1. Threshold of variation in terms of RMSSD between normal heartbeats enabling to predict the response to the course of rTMS with the best possible sensitivity and specificity.

    Threshold of variation in terms of RMSSD (root mean square of successive differences) between normal heartbeats after a single rTMS session enabling to predict the response to the course of rTMS with the best possible sensitivity and specificity. The response to the course of rTMS will be assessed via the evolution of the MADRS score (decrease of MADRS score >50%)

    Measured: One day for heart rate variability records (Before and after the first rTMS session), and 6 weeks for assessing the MADRS scores (before and after the course of 30 rTMS sessions)

Secondary outcomes (2)
  1. Threshold of other heart rate variability markers enabling to predict the response to the course of rTMS with the best possible sensitivity and specificity.

    Threshold of variation in other heart rate variability markers (SDNN, low frequencies, high frequencies and low to high frequencies ratio) after a single rTMS session enabling to predict the response to the course of rTMS with the best possible sensitivity and specificity. The response to the course of rTMS will be assessed via the evolution of the MADRS score (decrease of MADRS score >50%)

    Measured: One day for heart rate variability records (Before and after the first rTMS session), and 6 weeks for assessing the MADRS scores (before and after the course of 30 rTMS sessions)

  2. Threshold of variation in heart rate variability markers enabling to predict the remission to the course of rTMS with the best possible sensitivity and specificity.

    Threshold of variation in heart rate variability markers (RMSSD, SDNN, low frequencies, high frequencies and low to high frequencies ratio) after a single rTMS session enabling to predict the remission to the course of rTMS with the best possible sensitivity and specificity. The remission to the course of rTMS will be assessed via the evolution of the MADRS score (MADRS ≤ 10 after the course of rTMS)

    Measured: One day for heart rate variability records (Before and after the first rTMS session), and 6 weeks for assessing the MADRS scores (before and after the course of 30 rTMS sessions)

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted11 Jun 2024
  2. Study start13 Jun 2024
  3. Primary completion15 Apr 2025 (estimated)
  4. Study completion1 Jun 2025 (estimated)

Why it stopped: We are faced with a decrease in rTMS activity at the study sites, as well as problems with the active file meeting the protocol inclusion criteria, resulting in a low recruitment rate and an extended study timetable, forcing us to suspend this study.

Questions about this trial

What is this clinical trial studying?

An observational study of Major Depressive Disorder, run by GCS CIPS at 9 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 7 inclusion and 16 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: paused, as of the sponsor's last update on 12 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 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?

Results are not available in the source record.

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?

Threshold of variation in terms of RMSSD between normal heartbeats enabling to predict the response to the course of rTMS with the best possible sensitivity and specificity. (time frame: One day for heart rate variability records (Before and after the first rTMS session), and 6 weeks for assessing the MADRS scores (before and after the course of 30 rTMS sessions)). 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 12 Mar 2025.
