Repetitive Transcranial Magnetic Stimulation in Pharmaco-naïve Patients

Status Recruiting

Clinical Trial Summary

Repetitive transcranial magnetic stimulation (rTMS) has become a safe and efficacious treatment for patients with treatment-resistant depression. In several studies investigating the antidepressant efficacy of rTMS, it has been shown that in low treatment-resistant patients rTMS is more efficacious than in patients where several treatment attempts have failed. Albeit this finding, most studies to date primarily recruited patients with relatively high degrees of treatment-resistance and there is a lack of trials investigating rTMS as a first-line treatment. Therefore, this trials aims to compare the antidepressant efficacy of 4 weeks open-label theta-burst TMS in non-treatment-resistant patients with a comparable group of treatment-resistant MDD patients.

Clinical Trial Description

Repetitive transcranial magnetic stimulation (rTMS) has become a safe and efficacious treatment for patients with treatment-resistant depression (Mutz et al., 2019). Consequently, several countries including Australia, Brazil, Canada, Israel and the United States have approved rTMS as second-line treatment for major depressive disorder (MDD), while others have included rTMS in their guidelines for good clinical practice (e.g. Finland, Germany and Serbia). Historically, rTMS was conceptualized as a "soft" alternative to electroconvulsive therapy. Therefore, most studies to date primarily recruited patients with relatively high degrees of treatment-resistance (> two failed treatment attempts) and there is a lack of trials investigating rTMS as a first or second line treatment. This finding is contrasted by the fact that on the most stable predictors of response to rTMS is low-treatment resistance. Therefore, this trial aims to compare the antidepressant efficacy of 20 pharmaco-naïve patients with 20 treatment-resistant patients diagnosed with major depressive disorder. In this open label trial, patients will receive four weeks high-frequency left-sided theta burst TMS (lDLFPC). The target will be located by neuronavigation to the target ascertained by Fox et al. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
