Summary

This study was designed to explore how the drug ruxolitinib affects immune cells inside prostate tumors. Researchers planned to give the drug to men with prostate cancer for 28 days before their scheduled surgery, then analyze tumor and blood samples. However, the study was withdrawn before enrolling any participants, so no results are available.

What this could mean
