Neuroimaging Predictors of Relapse During Treatment for Opiate Dependence
Study Details
Study Description
Brief Summary
This study proposes to use functional magnetic resonance imaging (FMRI) to observe brain activity and behavior associated with decision-making about rewards (DD task), working memory and working memory cognitive persistence (WM task), and craving (CR task) in 72 opiate dependent participants initiating buprenorphine. While stably using opiates (initial study appointment) and again during withdrawal (approximately 3 days later), participants will receive an FMRI scan with behavioral challenges; immediately after the second FMRI, they will receive their first dose of buprenorphine. Buprenorphine treatment will continue for twelve weeks, followed by a four week taper. Urine toxicological analysis will be performed prior to the first scanning session, weekly for two weeks and biweekly thereafter.
Participation for all individuals will last 4 months. Assessments will occur at baseline, and weeks 1, 2, 4, 8, and 12. Buprenorphine induction will begin at the completion of the second scan; follow-up medical visits will align with study assessments on weeks 1, 2, 4, 8 and 12. All participants will receive 16 weeks of buprenorphine (the final 4 of these 16 weeks will include a taper).

Outcome Measures
Primary Outcome Measures
- Changes in Resting State Disorganization Between Baseline and One Week by Person by Lapsed Category [Baseline and 1 week]
The measure of resting state organization is a z-value derived from Pearson's r-values. They represent the effect of the association between the brain activity of the seed region and each brain voxel over time during the resting state FMRI scan. A central z-value of 0 means that there is no association between the seed region and the voxel. Positive and negative z-values approaching 0 reflect increasingly weaker associations, and more extreme positive and negative values reflect stronger associations. Attributing the qualitative labels better or worse to these values depend upon the brain network and context. In many networks (eg, task-positive cognitive control network), a stronger positive correlation is thought to reflect better network organization. In the task-negative default mode network a stronger positive relationship is considered by some as worse. For this study, these are not yet used as clinical measures and there are not known cutoffs.
