Summary

This study tested the drug niraparib, given before surgery, in 11 men with high-risk prostate cancer that had not spread. The drug targets tumors with specific DNA repair defects. The trial was stopped early, so results are limited, but the goal was to see if the drug could shrink or eliminate the cancer before removal.
