Clinical Trial Summary

The purpose of this study is to see how stress influences the effects of opioid pain medications often used to help relieve back pain. The study will help to learn more about how high stress levels could increase risk for pain medication misuse.


Clinical Trial Description

The purpose of this project is to advance mechanistic knowledge of how stress impacts differential opioid analgesic responses that enhance risk for opioid use disorder (OUD), potentially informing development of data-driven precision pain medicine algorithms to mitigate opioid related risks. The study aims to determine whether subjective and physiological stress-related measures are associated with analgesic and misuse-relevant subjective responses to placebo-controlled oxycodone administration. The study also aims to evaluate associations between stress-related measures and both endogenous opioid (EO) function and endocannabinoid (EC) levels and to test whether EO and EC mechanisms contribute to associations between stress-related measures and oxycodone responses Using a mixed between/within-subject design, the study will obtain baseline assessment of stress related markers followed by 3 laboratory sessions with assessment of endocannabinoids, back pain assessment, and exposure to standardized evoked pain stimuli after administration of placebo, naloxone, and oxycodone. ;
