Neoadjuvant And Adjuvant Abiraterone Acetate + Apalutamide Prostate Cancer Undergoing Prostatectomy
a study on Prostate Cancer
This research study is studying a combination of drugs called abiraterone acetate and Apalutamide as a possible treatment for new diagnosed Prostate Cancer. The following interventions will be use in this study : - Abiraterone Acetate - Prednisone - Apalutamide - Leuprolide Acetate
Phase II Randomized Study Of Neoadjuvant And Adjuvant Abiraterone Acetate + Apalutamide For Intermediate-High Risk Prostate Cancer Undergoing Prostatectomy
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied.
The FDA (the U.S. Food and Drug Administration) has approved Abiraterone acetate with prednisone as a treatment option for prostate cancer that has spread to other parts of the body (metastatic castration-resistant prostate cancer).However, in this study it is being investigated for the treatment of localized prostate cancer prior to surgical removal of the prostate (prostatectomy).
Abiraterone acetate works by decreasing the production of androgens (male sex hormones), which promote prostate cancer growth. Some steroids produced by the adrenal glands can turn into testosterone, and prostate cancer cells feed on testosterone. Testosterone is suppressed by an FDA approved drug called leuprolide or Lupron.
The FDA has not approved Apalutamide as a treatment for any disease. In this study, Apalutamide is being investigated for the treatment of prostate cancer. Apalutamide also works by blocking the effects of male sex hormones.
In this research study, the investigators are studying the effectiveness of one combination of drugs (abiraterone acetate + prednisone + leuprolide) compared to another combination of drugs (abiraterone acetate + prednisone + leuprolide + Apalutamide) before surgery to see if this will improve surgical outcomes and reduce or eliminate Prostate Cancer.

Participant must also agree not to donate sperm during the study and for 3 months after receiving the last dose of study drug.
- . Medications known to lower the seizure threshold (see list under APPENDIX D: Representative Medications that May Predispose to Seizure) must be discontinued or substituted at least 1 week prior to study treatment.
You CAN'T join if...

Prior therapy with 5α-reductase inhibitors is allowed. LHRH therapy allowed if begun within 4 weeks of day 1.
