Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 60 with major depressive disorder, a MADRS score of 15 or higher, MoCA above 24, and fluent in English or Spanish, who are seeking antidepressant treatment.

Probably not a fit

Patients with other serious psychiatric or neurological conditions, recent suicidality, or MRI contraindications may have no benefit from the intervention.

What this trial studies

This Phase 2 interventional trial investigates whether clemastine fumarate, combined with standard antidepressant therapy, can improve white matter integrity and enhance antidepressant response in adults over 60 with major depressive disorder. Participants are randomized to receive clemastine or placebo for 12 weeks while continuing their usual antidepressant treatment. Primary outcomes include changes in brain white matter measured by imaging, along with mood and cognitive assessments, and safety monitoring. The study targets late-life depression, where white matter health may influence treatment outcomes. Recruitment is conducted at the University of Illinois College of Medicine in Chicago with collaboration from Cures Within Reach.

Why it matters

Potential benefit: If successful, participants may experience greater improvement in depressive symptoms and cognitive function due to better brain connectivity and response to antidepressants.

How similar studies have gone: Prior research suggests white matter integrity can influence treatment response in depression, and repurposing clemastine has shown potential for supporting brain repair, though this specific combination in late-life depression is investigational.
