Pharmacogenetic-Guided Antidepressant Treatment in Depression
Pharmacogenetic-Guided Antidepressant Treatment for Major Depressive Disorder: A Randomized Controlled Trial in Morocco
Source: ClinicalTrials.gov · Last updated 9 Apr 2026
Brief summary (registry, in English)
The purpose of this clinical trial is to evaluate whether using pharmacogenetic testing to guide antidepressant treatment can improve outcomes in adults with major depressive disorder in Morocco. Depression is a common mental health condition, and finding the most effective antidepressant for a patient can take time. Some individuals do not respond well to the first medication prescribed or may experience side effects. Pharmacogenetic testing examines genetic variations that can influence how a person processes certain medications. Information about genes involved in drug metabolism, such as CYP2D6 and CYP2C19, may help clinicians choose antidepressants and adjust doses more appropriately for each patient. The main question this study aims to answer is whether treatment guided by pharmacogenetic test results leads to higher remission rates of depressive symptoms compared with usual clinical care. In this study, participants diagnosed with major depressive disorder will be randomly assigned to one of two groups. In the pharmacogenetic-guided group, clinicians will receive the patient's genetic test results and may use this information to guide antidepressant selection and dosing. In the usual care group, antidepressant treatment will be prescribed according to standard clinical practice without access to pharmacogenetic information. Participants will receive antidepressant treatment and will be followed for 12 weeks. During this period, depressive symptoms will be evaluated using standardized clinical questionnaires, including the Patient Health Questionnaire (PHQ-9). Information on treatment response, medication tolerance, and adverse effects will also be collected. This study aims to provide evidence on the potential role of pharmacogenetic-guided treatment in improving depression management and to support the development of personalized medicine approaches in psychiatric care in Morocco.
