Official title

CSP #576 - VA Augmentation and Switching Treatments for Improving Depression Outcomes (VAST-D)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The overall purpose is to determine research based 'next-steps' for outpatients with major depressive disorder who have not had satisfactory outcomes to standard 'first-step' treatments. The primary objective is to compare the acute (up to 12 weeks) treatment effectiveness of augmenting an antidepressant with aripiprazole or with bupropion-slow release (SR) vs. switching treatment to bupropion-SR monotherapy on symptom remission in Veterans with Major Depressive Disorder (MDD) who have not achieved optimal response after an adequate trial on antidepressant (a selective serotonin reuptake inhibitor \[SSRI\] or serotonin and norepinephrine reuptake inhibitor \[SNRI\] or mirtazapine) monotherapy. The secondary objectives are to compare the acute (up to 12 weeks) and long term (up to 36 weeks) efficacy, safety, effects on functioning, suicidality, quality of life, anxiety and other associated symptoms, costs and cost-effectiveness of each of the three treatments.
