Pharmacist Guided Pre-emptive Pharmacogenetic Testing for Antidepressant Therapy in Depression A Randomized Study Comparing Genetic Testing and Standard Care

What this Trial Is About

Researchers are evaluating how effective and tolerable antidepressant treatments are when guided by pharmacist-led genetic testing compared to standard care in adults with depression. The study focuses on patients diagnosed with moderate or severe unipolar depressive episodes or recurrent depressive disorder. The purpose is to see if using genetic information to select and dose antidepressants improves treatment response during hospitalization. Participants are randomly assigned to one of two groups after the first week of hospitalization if the treating physician decides a medication change is needed. In the intervention group, clinical pharmacists perform genetic testing using the Stratipharm® service and provide personalized medication recommendations to the psychiatrist. The standard group receives antidepressant treatment selected and dosed by the physician without genetic testing. All drugs used are approved in Switzerland for depression treatment. If no change in medication is needed after the first week, patients enter an observational arm and continue monitoring. Patients remain hospitalized for at least five weeks and are monitored until discharge. Researchers assess treatment response at 4 weeks by measuring improvement in depression symptoms. Throughout the study, patients' medication history, co-medications, and progress are tracked. The study plans to enroll 95 patients each in the intervention and standard groups, evaluating how genetic-guided therapy affects antidepressant response and tolerability.
