More critically, there are also no reliable predictors that might anticipate failure to such standard treatments either alone or in combination. This project will characterize imaging-based brain subtypes that distinguish groups of depressed patients who later remit or not to SSRI pharmacotherapy or cognitive behavior therapy (CBT), respectively. To define these subtypes, a prospectively-treated cohort of 100 patients will be randomized to receive either escitalopram (s-CIT) or CBT for the first 12 weeks, with non-remitters to either first treatment crossed over to receive an additional 12 weeks of treatment with combined treatment. Non-remitters to both treatments will thus define a relatively treatment resistant third subgroup. Resting-state 18F-fluoro-deoxyglucose (FDG) positron emission tomography (PET) scans will be acquired prior to initiating antidepressant therapy, with pre-treatment scan patterns associated with three possible outcomes (CBT remission, s-CIT remission, and non-remission to both) assessed using multivariate analytic methods. A second PET scan, acquired early in the treatment course, will be used to assess the likelihood of response to the specific treatment first assigned. The proposed studies are a first step towards defining brain-based biomarkers predictive of differential treatment outcome in major depression; most critically, patterns distinguishing patients at risk for treatment resistance. Identification of such biomarkers has additional implications for future testing of novel therapies in patients with distinct brain signatures, including development of evidence-based treatment algorithms for individual patients.","detailedDescription":"SPECIFIC AIMS Aim 1. To define baseline regional glucose metabolic patterns (measured using FDG PET) associated with differential clinical remission to each of two well-established, randomly delivered first-line antidepressant treatments-the SSRI escitalopram (s-CIT) or cognitive behavioral therapy (CBT) with cross-over treatment for non-remitters (sequential course of treatment model).\n\nAim 2. To define metabolic change patterns, occurring early in the course of both s-CIT and CBT, associated with successful and unsuccessful clinical remission to each intervention."},"conditionsModule":{"conditions":["Major Depressive Disorder"],"keywords":["Depression, Treatment, Imaging"]},"designModule":{"studyType":"INTERVENTIONAL","phases":["NA"],"designInfo":{"allocation":"RANDOMIZED","interventionModel":"CROSSOVER","primaryPurpose":"TREATMENT","maskingInfo":{"masking":"NONE"}},"enrollmentInfo":{"count":82,"type":"ACTUAL"}},"armsInterventionsModule":{"armGroups":[{"label":"Escitalopram","type":"OTHER","interventionNames":["Drug: escitalopram"]},{"label":"Cognitive Behavioral Therapy","type":"OTHER","interventionNames":["Behavioral: Cognitive Behavioral Therapy (CBT)"]}],"interventions":[{"type":"DRUG","name":"escitalopram","description":"Participants will receive treatment with escitalopram for 12 weeks.","armGroupLabels":["Escitalopram"],"otherNames":["Lexapro"]},{"type":"BEHAVIORAL","name":"Cognitive Behavioral Therapy (CBT)","description":"CBT will include 16 1 hour sessions provided over 12 weeks.","armGroupLabels":["Cognitive Behavioral Therapy"],"otherNames":["Talk Therapy"]}]},"outcomesModule":{"primaryOutcomes":[{"measure":"Remission Defined as Hamilton Depression Rating Scale-17 Score of Less Than or Equal to 7 at 12 Weeks","description":"\\# of study participants with Hamilton Depression-17-item score less than or equal to 7.","timeFrame":"Measured at week 12"}],"secondaryOutcomes":[{"measure":"Response Defined as 50% Change in Hamilton Depression Rating Scale-17 Score at 12 Weeks","description":"Number of participants with a 50% change from Baseline on the Hamilton Depression Rating Scale-17-item score","timeFrame":"Measured at week 12."}]},"eligibilityModule":{"eligibilityCriteria":"Inclusion Criteria:\n\n* Male or female patients between the ages of 18 and 60.
