What the trial is, and whether it could suit you
The goal of this project is to quantify the effectiveness and safety of escitalopram oxalate oral solution in the treatment of first-episode, drug-naïve patients with major depressive disorder, and to explore the mechanisms underlying its antidepressant effects using multi-omics approaches. By integrating clinical, cognitive, laboratory, imaging, genetic, and environmental data, the study aims to identify patient subgroups who are most likely to benefit from escitalopram, thereby promoting individualized and precision treatment for depression.
This multicenter, prospective, single-arm intervention study will enroll 200 adults aged 18-65 years with major depressive disorder, who will receive escitalopram oxalate oral solution for 8 weeks. Depressive symptoms, cognitive function, and adverse events will be assessed at baseline, during treatment, and after 8 weeks of treatment to evaluate
