VAPORHCS/OHSU J: A Phase 3 Study of Androgen Annihilation in High-Risk Biochemically Relapsed Prostate Cancer (VA#4526)

Principal Investigator

Mark Garzotto

Study Purpose

The purpose of the study is to compare any good and bad effects of adding an experimental drug called apalutamide to degarelix or lupron, or adding apalutamide in combination with abiraterone acetate to degarelix or lupron, to see if there's a difference between those treatments and the effect that degarelix or lupron monotherapy has on biochemically recurrent prostate cancer.

Prostate Cancer
Biochemically recurrent prostate cancer
