Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
More than one out of three individuals treated for major depressive disorder (MDD) do not experience a full reduction of symptoms even when treated with adequate antidepressant medication. These individuals may have treatment-resistant depression. This is a condition that contributes to the tremendous costs of MDD, in terms of health care costs, functional impairment (limitation of an individual's functional ability), and diminished quality of life. There is a clear need for personalized medicine, for people at high risk for treatment-resistant depression. If these individuals could be identified early in the course of their depression, they could be recommended for more intensive or specialized interventions. Doing so could improve their likelihood of having a full reduction in their symptoms. Today, there are many treatment options for MDD. Individuals can spend months or years in and out of treatment before receiving one that works for their treatment-resistant depression. The investigators want to study treatment resistant depression by examining specific genes (genotyping) that might influence how your body responds to certain antidepressant medications. This process of examining specific genes is not experimental. To look at your specific genes, the investigators will collect a blood sample. Genes contain the material passed from parent to child that determines the make-up of the body and mind. For example, some genes control the color of your hair or eyes. Genes are contained in your DNA (deoxyribonucleic acid). There are many differences in DNA, from one person to another. These differences may affect a person's chances of having a particular disease.
