Identifying pain-related bio-signatures for better pain management

Discovery and Analytical Validation of Inflammatory Bio-signatures of the Human Pain Experience

Phase 1 Interventional The University of Texas Health Science Center, Houston · NCT05074485

This study is testing a new way to predict pain after surgery by looking at how certain body signals change during pain and seeing if an anti-inflammatory drug can help manage that pain better.

What this trial studies

This study aims to discover and validate a novel bio-signature derived from IL-1 family cytokine activity that can predict pain experiences and the release of endogenous opioids during a nociceptive pain challenge. Healthy subjects will undergo this challenge while their mu-opioid receptor activity is measured using PET neuroimaging. Additionally, the study will assess the effects of the anti-inflammatory drug minocycline on pain perception and cytokine balance. The ultimate goal is to create a reliable tool for predicting post-operative pain, particularly after elective cosmetic surgeries.

Who should consider this trial

Good fit: Ideal candidates are individuals awaiting elective surgery, regardless of obesity status, who meet the inclusion criteria.

Not a fit: Patients with active severe medical or psychiatric illnesses, or those with recent substance abuse issues, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective pain management strategies for patients undergoing surgery.

How similar studies have performed: While the approach of using bio-signatures for pain prediction is innovative, similar studies have shown promise in related areas, indicating potential for success.
