A Study of Apalutamide in Participants With High‑Risk, Localized or Locally Advanced Prostate Cancer Who Are Candidates for Radical Prostatectomy

Overview

About this study

The purpose of this study is to determine if treatment with androgen deprivation therapy (ADT) plus apalutamide before and after radical prostatectomy in participants with high-risk localized or locally advanced prostate cancer results in an improvement in pathological complete response (pCR) rate and metastasis-free survival (MFS), as compared to ADT plus placebo.

  • Nodal disease below the iliac bifurcation (clinical stage N1) is not an exclusion.
  • Diagnosis of distant metastasis (clinical M stage; M0 versus M1a, M1b, M1c) and pelvic nodal disease (clinical N stage; N1 versus N0) will be assessed by central radiological review.
