Brief Summary | The purpose of this study is to compare the safety and efficacy of buprenorphine with placebo for adults with treatment resistant depression (TRD). |
||||
Detailed Description | Rates of treatment resistant depression (TRD) in randomized controlled trials range from 50-80% using SSRIs and SNRIs. Innovative treatments are sorely needed. Modulation of the opiate system may be a novel treatment approach for TRD. Buprenorphine (BUP) is a partial agonist at mu-receptors, and also displays affinity for kappa and delta receptors. BUP has a favorable safety profile with low risk of respiratory depression, and the pharmacokinetics are not affected by advanced age or renal dysfunction. This combination of mu-agonism and kappa-antagonism produces less dysphoria than methadone, and animal studies suggest that kappa-antagonism may exert antidepressant effects. In this small proof of concept RCT (n=20), the investigators hypothesize that there will be differences between the group receiving buprenorphine and the group receiving placebo for the following: 1) depression, anxiety, and sleep, and 2)activation of the limbic system and brain structures rich in opiate receptors and critical to reward circuits. In addition, the investigators hypothesize that there will not be differences for measures of safety (vital signs, measures of memory and reaction time, and falls) between the two groups. This pilot project will provide compelling preliminary data to support a R01 application to test the efficacy of buprenorphine for these therapeutically challenging patients. Specific Aims:
The investigators are recruiting 20 community-dwelling adults, age 21 and older, who have tried at least two FDA-approved antidepressant medications at therapeutic doses each for at least 6 weeks during this episode of depression, and are still depressed. |
