NCT04441008

Brief Summary

The overall objective of this current study is to evaluate the feasibility, safety, and tolerability of "high dose" aiTBS in psychiatric inpatient and outpatients with treatment-refractory unipolar, non-psychotic major depressive disorder, using patients receiving ECT as an active comparator. Developing a better understanding of the feasibility and tolerability of adapting this treatment to an acutely ill patient population could lead to huge breakthroughs for clinician decision-making and for the further optimization of brain stimulation depression protocols. The results of this study can help guide future confirmatory efficacy trials of high-dose aiTBS by providing a better understanding of how feasibility, safety and tolerability compare to ECT, as well as unforeseen challenges of its use.

Outcome Measures

Primary Outcomes (1)

  • Retention rate at completion of aiTBS vs the ECT group

    The primary tolerability endpoint is the proportion of aiTBS or ECT patients completing the protocol to a degree thought to be satisfactory for achieving the intended antidepressant effect. Completion for aiTBS arm is defined as completion of at least 60% of the treatment protocol (30 of 50 treatments) with treatments on at least 60% of days (3 of 5 days during the week). Completion for ECT arm is defined as completion of at least 2 of 3 ECT treatments during the first week.

    5 days

Study Arms (2)

aiTBS arm

EXPERIMENTAL

aiTBS treatment as lead-in phase to ECT standard of care treatment.

Device: Accelerated Intermittent Theta Burst (aiTBS)Device: Electroconvulsive therapy (ECT)

ECT arm

ACTIVE COMPARATOR

ECT as clinically indicated.

Device: Electroconvulsive therapy (ECT)

Interventions

High-dose intermittent theta burst administered at a treatment frequency 10x per day, with each treatment session duration 3x standard TMS (1800 pulses). Delivering 50 sessions in 5 days.

Also known as: SAINT Protocol, accelerated TMS
aiTBS arm

ECT as per standard clinical care and management.
