Prostate Cancer Study

This is a study of an investigational medication for prostate cancer.

Participants must have prostate cancer, with rising PSAs, that has been treated with surgery or radiotherapy, and has not spread to other parts of the body.

Patients may not have received prior hormonal therapy and no prior cytotoxic chemotherapy or systemic biologic therapy, including immunotherapy, for prostate cancer.

Eligible participants will:

  • Potentially receive an investigational non-surgical medication at no cost
  • Have regular visits with prostate cancer specialists
  • Receive compensation for time and travel

Study visits occur approximately every 12 weeks. The estimated duration of the study will be up to approximately 5 years. There will be 3 different treatment groups in this study to which patients will be randomly assigned. That means patients will have an equal chance (33%) of taking any 1 of these 3 treatments:

  • Group 1:  Enzalutamide 
  • Group 2:  Enzalutamide and leuprolide 
  • Group 3:  Placebo (contains no drug) and leuprolide

Clinical trials help doctors and scientists better understand and treat prostate cancer.
