Summary

This study tests a new drug called GDC-1261 in 260 people with advanced or metastatic prostate cancer that has worsened after prior treatment. The goal is to check the drug's safety, find the best dose, and see if it can shrink tumors or lower PSA levels. Participants must already be on hormone therapy.
