General Information

Apalutamide, also known as ARN-509, is used to treat certain types of castration-resistant prostate cancer or prostate cancer that has not spread to other parts of the body, but has not been helped by other medical treatments. Apalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen to stop the growth and spread of cancer cells.

On September 17, 2019, the Food and Drug Administration approved apalutamide (ERLEADA, Janssen Biotech, Inc) for patients with metastatic castration-sensitive prostate cancer (mCSPC). Apalutamide was initially approved in 2018 for patients with non-metastatic castration-resistant prostate cancer.
