Anti-suicidal Effects of Buprenorphine in Opioid Use Disorder

Status Withdrawn

Clinical Trial Summary

The study aims to examine the effect of buprenorphine on suicidal ideation in individuals with opioid use disorder, and to investigate the functional brain activity related to its potential anti-suicidal effect.

Clinical Trial Description

The current opioid epidemic is an urgent public health problem, contributing significantly to the climbing U.S. suicide rates over the past two decades. Although initially rewarding, chronic opioid use leads to tolerance and escalating negative affective states. This may promote suicidal ideation and may further impair decision-making functions leading to suicidal behavior. Buprenorphine, a treatment for opioid use disorder (OUD), has promise in reducing suicidal ideation. However, the neural mechanism of its anti-suicidal properties remains unknown. Blocking kappa opioid receptors is one mechanism of buprenorphine hypothesized to reverse the negative emotional sensitivity in OUD and thus may underlie its anti-suicidal effects. In this morphine-controlled study, we will examine the effect of buprenorphine on the functional activity of brain regions involved in negative emotional reactivity and investigate whether this effect is associated with its anti-suicidal properties. Buprenorphine has a different mechanism of action than currently available antidepressants and anti-suicidal medications. Understanding this mechanism can help refine its use in this context. Success will guide a future larger study to elucidate molecular mechanisms underlying anti-suicidal properties of buprenorphine. ;
