Depression dose study pulled before starting
NCT ID NCT05210153
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if measuring sertraline (Zoloft) levels in the blood and checking a specific gene (CYP2C19) could help doctors give the right dose to people with major depression. The goal was to reduce side effects and improve treatment. However, the study was withdrawn before enrolling any participants, so no results are available.
