NCT ID NCT02051413

First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This study looked at whether certain proteins called beta-arrestins can predict how well people with major depression respond to the antidepressant venlafaxine (Effexor). Researchers followed 67 patients for three months, measuring their depression symptoms and checking blood samples for these proteins. The goal was to find a simple biological marker that could help doctors choose the right treatment from the start.
