The Investigators are conducting a research study to learn about the safety and benefit of using a medication called buprenorphine for patient with difficult to treat depression . This research study is testing whether combining two medications will be effective in treating depression when initial treatment with just one antidepressant does not relieve the depressive symptoms ; this is what is called " difficult to treat depression " or " treatment resistant depression ". The two medication the investigators are using are " an anti-depressant medication called venlafaxine XR ( the generic form of Effexor ) and buprenorphine . Buprenorphine is a medication that is FDA approved for the treatment of opioid dependence. The investigators are testing whether adding buprenorphine to venlafaxine enhances treatment response.


The aim of this study is to examine the feasibility, safety, and tolerability of buprenorphine (BPN) as a novel treatment for late-life treatment resistant depression (LL-TRD). The investigators aim to use a clinical trial methodology common to all three sites, and to examine the mechanism of action (MOA) of BPN using translational neuroscience methods. Over ½ of seniors with depression fail to respond to traditional antidepressants.19,20 Modulation of the opiate system with BPN offers a novel mechanistic approach to improve the lives of patients with LL-TRD, with a safety profile potentially superior to current augmentation strategies such as antipsychotics, lithium, ECT, and surgical interventions (e.g., deep brain or vagal nerve stimulation).
