Exploring spinal stimulation for treating major depressive disorder

Modulating Spinal Interoceptive Pathways to Evaluate Their Role and Therapeutic Potential in MDD Symptomatic Domains

Phase1; Phase2 Interventional University of Cincinnati · NCT06795451

This study is testing if a new type of spinal stimulation can help people with major depressive disorder feel better by targeting specific pathways in the spine and brain.

What this trial studies

This study investigates the role of spinal interoceptive pathways in major depressive disorder (MDD) by using non-invasive spinal cord stimulation techniques. The research aims to evaluate how transcutaneous spinal direct current stimulation (tsDCS) can modulate these pathways and assess their therapeutic potential. Participants will undergo assessments to measure the engagement of spinal and brain-based pathways, with a focus on determining the optimal stimulation dose. The study employs a phased innovation approach to gather insights into the effectiveness of this novel treatment method.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 60 with a current episode of major depressive disorder who are stable on antidepressant medication.

Not a fit: Patients with treatment-resistant depression or those with a history of bipolar disorder or schizophrenia may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new non-invasive treatment option for patients suffering from major depressive disorder.

How similar studies have performed: Preliminary data suggests that targeting spinal interoceptive pathways may be a feasible therapeutic approach, although this specific method is relatively novel.
