Sequencing Abiraterone and Enzalutamide in mCRPC

Summary

This study is being offered to patients who have castrate-resistant (also known as hormone-refractory) prostate cancer. The cancer has metastasized or spread outside the prostate area to other parts of the body. The purpose of this study is to evaluate the effects of sequencing hormonal therapies (abiraterone acetate and enzalutamide) and to assess treatment efficacy of these two agents.
