Precision Mental Health: Evaluating Biotype-guided Interventions for Depression

Stanford University·interventional·Posted Nov 29, 2019·Updated Mar 20, 2025

In Brief

A Phase 4 clinical trial evaluating Guanfacine Tablets for Major Depressive Disorder. Completed, enrolled 28 participants across 1 site.

Detailed Summary

Cognitive impairments contribute significantly to psychosocial dysfunction in major depressive disorder (MDD) and respond poorly to conventional antidepressants, yet selective treatments targeted to these impairments are lacking. Our previous research identified a distinct subgroup of depression called "cognitive biotype+" that comprises 27% of depressed patients and is characterized by pre-treatment global cognitive impairments and dysfunction in the cognitive control neural circuit. In this study, we evaluated the medication guanfacine immediate release (GIR), an alpha 2A receptor agonist, as a novel treatment for selectively improving cognitive control circuit function, performance on cognitive testing, and clinical measures the cognitive biotype+ subgroup.
