February 13, 2024 updated by: Centre Hospitalier Rouffach

Added Value of a Neuroendocrine Test Battery in the Response to Repetitive Transcranial Magnetic Stimulation (rTMS) Treatment : a Pilot Study in Major Depression (Endo-rTMS)

The primary objective of the study is to determine the predictive value of the neuroendocrine tests TRH-∆∆TSH (thyreoliberin - thyreostimulin) and DST (dexamethasone suppression test) in the subsequent response to rTMS-TBS (repetitive transcranial magnetic stimulation-theta burst stimulation) treatment, defined as at least a 50% decrease in depression score after 20 sessions of rTMS-TBS.

Detailed Description

Conduct of research :

This is a monocentric, non-randomized, open-label pilot study involving 50 male and female patients aged 18 to 65, hospitalized for major depression and presenting with an indication for treatment with repeated theta-burst transcranial magnetic stimulation (rTMS-TBS), i.e. a situation of therapeutic failure following 2 well-conducted antidepressant treatments.

At the end of the 20 rTMS-TBS sessions (one session per day, except weekends), the clinical response will be assessed by an investigator "blind" to the endocrine results. This response will be analyzed according to the status of neuroendocrine tests at inclusion (TRH-∆∆TSH and DST) and at the end of the study (for those who had one or more abnormal tests at inclusion and in whom the same tests were repeated at the end of the rTMS-TBS sessions).

During the inclusion visit, the patient and investigator sign the consent form, after double-checking the inclusion and non-inclusion criteria.

Immediately after the tenth rTMS session, an assessment of depression using the HAMD (17-item Hamilton Depression Scale) scale will be carried out by an independent psychiatrist, blind to the results of the neuroendocrine tests. This psychiatrist, who has already administered the HAMD at V0, will repeat the assessments at V1 and V2.

Immediately after the twentieth rTMS session, an assessment of depression using the HAMD scale will be carried out by an independent psychiatrist. This assessment will determine responder/non-responder status to rTMS-TBS.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  4. Patient with written informed consent to participate in the study;
  5. Patient enrolled in or receiving social security benefits.

Exclusion Criteria:

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Experimental: Treatment resistant major depressed inpatients (TRDs)
Procedure: Repetitive transcranial magnetic stimulation (rTMS)
The theta burst stimulation (TBS) technique consists in administering bursts of transcranial magnetic stimulation (TMS) at very high frequency (50Hz) for 5 minutes (3 pulses of stimulation given at 50 hz; 10 bursts/1 s train; inter-train interval : 8 s; number of trains : 30; 100% resting motor threshold; number pulses/session : 900). Total number of sessions : 20 sessions (single daily session).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
17-item Hamilton Depression Scale (HAMD)
Time Frame: Change from inclusion result at 6 weeks (after 20 rTMS-TBS sessions)
Clinical response will be defined by at least a 50% decrease in depression score at the end of the 20 rTMS-TBS sessions - measured by the 17-item Hamilton Depression Scale (HAMD) - compared to inclusion (Carrozzino et al, 2020). The predictive value of the TRH-∆∆TSH on the one hand, and the DST on the other, will be assessed using an ROC curve and its AUC (Area Under the Curve) calculation.
Change from inclusion result at 6 weeks (after 20 rTMS-TBS sessions)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
