Brief Summary

The aim of this randomized multicentre phase 2 clinical trial is to compare the effects of rTMS and SSRI medication as early treatment of depression. In this two-stage, therapy response-adapted trial, 106 patients suffering from non-treatment resistant major depression (non-TR MD) will be randomized in Stage I to either 4 weeks bilateral theta burst stimulation (TBS) or 4 weeks antidepressant SSRI medication. The allocation to Stage II occurs therapy response-adapted. Patients receive either a maintenance treatment or a switch to the respective other treatment arm. The primary outcome is the comparison of the two study arms with regard to therapy response measured with the Montgomery-Asberg Depression Rating Scale (MADRS) after 4 weeks at the end of Stage I.

Outcome Measures

Primary Outcomes (1)

  • response rates after Stage I

    The primary endpoint is the comparison of the two study arms with regard to the number of participants achieving therapy response (reduction of MADRS score ≥ 50%) after 4 weeks at the end of Stage I.

    4 weeks

Study Arms (2)

theta burst stimulation (TBS)

EXPERIMENTAL

In Stage I, participants receive 4-week bilateral theta burst stimulation. Bilateral TBS consists of 20 sessions that are conducted daily from Monday to Friday over a period of 4 weeks. The target regions are the right and left dorsolateral prefrontal cortex (dlPFC). On the left hemisphere, intermittent TBS (iTBS) is applied, which has a stimulating effect on the target region similar to 10 Hz rTMS. On the right dlPFC, continuous TBS (cTBS) is applied, which has an inhibitory effect similar to 1 Hz rTMS.

Device: bilateral theta burst stimulation

SSRI treatment

ACTIVE COMPARATOR

In Stage I, participants receive escitalopram (10mg/day) as standard medication for 4 weeks. In justified individual cases and according to the decision of the study physician, a higher dose or another SSRI can be administered.

Drug: SSRI treatment

Interventions

Each stimulation session consists of 600 stimuli applied in bursts of 3 pulses at 50 Hz, with an interstimulus interval of 200 ms. iTBS is administered 20 times for 2 seconds to the left dlPFC, with an intertrain interval of 8 seconds and cTBS continuously for 40 seconds to the right dlPFC in alternating order.

theta burst stimulation (TBS)

Participants receive 4 weeks SSRI treatment with escitalopram (10mg/day) as standard drug.

SSRI treatment
