JNJ 927 (apalutamide) filed with FDA for non-metastatic castration-resistant prostate cancer.- Janssen Biotech.

Janssen Biotech announced that it has submitted a New Drug Application (NDA) to the FDA for JNJ 927 (apalutamide), an investigational, next generation oral androgen receptor (AR) inhibitor for men with non-metastatic castration-resistant prostate cancer (CRPC). Currently, there are no FDA approved treatments for patients with non-metastatic CRPC.

This submission is based on Phase III data from the pivotal ARN-509-003 (SPARTAN) clinical trial, which assessed the safety and efficacy of apalutamide versus placebo, in men with non-metastatic CRPC who have a rapidly rising prostate specific antigen (PSA) despite receiving continuous androgen deprivation therapy (ADT). Men with non-metastatic CRPC with a rapidly rising PSA are at high risk for developing metastatic disease. The primary endpoint of this study was metastasis free survival (MFS). MFS is the time from randomization to first evidence of confirmed metastasis, or time to death. The SPARTAN study results will be presented at a future medical meeting.
