Pivotal Trial

Summary

This trial will test whether apalutamide can help treat prostate cancer that is not responding to hormone therapy and has not spread.

Who is the study for?
Men with non-metastatic castration-resistant prostate cancer, showing a high risk of developing metastases and having a PSA doubling time of 10 months or less. Participants must be on continuous ADT with rising PSA levels, maintain low testosterone, and have no prior treatments that disqualify them such as second-generation anti-androgens or chemotherapy for prostate cancer.
What is being tested?
The trial is testing the effectiveness and safety of Apalutamide compared to a placebo in men with high-risk non-metastatic castration-resistant prostate cancer. The goal is to see if Apalutamide can prevent the cancer from spreading.
What are the potential side effects?
Possible side effects include fatigue, joint pain, rash, weight loss, diarrhea, hot flushes, increased blood pressure and falls. More serious risks may involve fractures or seizures.
