Apalutamide: First Global Approval

Abstract

Apalutamide (Erleada^TM) is a next-generation oral androgen receptor (AR) inhibitor that is being developed by Janssen for the treatment of prostate cancer (PC). It binds directly to the ligand-binding domain of the AR and blocks the effects of androgens. In February 2018, apalutamide received its first global approval in the USA for the treatment of non-metastatic castration-resistant PC (nmCRPC). Apalutamide is undergoing phase III investigation in chemotherapy-naive patients with metastatic CRPC (in combination with abiraterone acetate plus prednisone), patients with high-risk localized or locally advanced PC receiving primary radiation therapy, and in patients with metastatic hormone-sensitive PC and biochemically-relapsed PC. This article summarizes the milestones in the development of apalutamide leading to this first approval in nmCRPC.
