Who this trial is looking for
This trial is looking for teens aged 14-21 who are seeking treatment for depression. Participants will undergo tests to see how stress affects their inflammation levels and how these relate to their response to medication over 12 weeks.

Despite the prevalence and significant public health concern over depression among adolescents, up to 40% of depressed adolescents do not respond to first-line antidepressants (herein termed treatment non-response, TNR). The goal of this project is to recruit and assess 160 treatment-seeking depressed adolescents and test whether acute stress impacts peripheral levels of inflammation and downstream levels of glutamate in corticolimbic regions previously associated with depression, whether these stress-related biomarkers predict TNR to a 12-week trial of either fluoxetine or escitalopram, and whether these stress-related biomarkers predict 18-month clinical course.
