What this trial studies

This trial evaluates the feasibility of a pragmatic approach to compare intermittent theta-burst stimulation (iTBS) and low frequency repetitive transcranial magnetic stimulation (LFR) in patients with treatment-resistant depression (TRD). The study aims to recruit 100 outpatients and assess various depression and anxiety scales while incorporating patient preferences and digital phenotyping for future trials. Key objectives include determining recruitment feasibility, retention rates, and patient engagement in treatment options when initial responses are inadequate.

Who should consider this trial

Good fit: Ideal candidates are outpatients aged 18 and older with treatment-resistant depression who meet specific inclusion criteria.

Not a fit: Patients with active suicidal intent, certain psychiatric disorders, or significant medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide new insights into effective treatment options for patients suffering from treatment-resistant depression and anxiety.

How similar studies have performed: Other studies have shown promise with similar approaches, but this trial aims to establish a novel pragmatic framework for evaluating treatment options.
