Summary

This study tests whether olanzapine, a medication typically used for mental health conditions, can reduce opioid cravings and misuse in adults with cancer who are on long-term opioid pain therapy. About 87 participants will receive either olanzapine or a placebo to see if it helps lower cravings safely. The goal is to improve pain management while reducing the risk of opioid misuse.
