Summary

This trial is testing a new combo of drugs for high-risk prostate cancer patients undergoing surgery. The drugs lower androgen levels, which can cause prostate cancer growth. Prednisone may either kill the tumor cells or stop them from dividing.

Who is the study for?
Men with high-risk prostate cancer who are planning to undergo surgery can join. They must have a Gleason score >8 or PSA >20, be in good physical condition (ECOG PS 0 or 1), and have no metastatic cancer or severe heart conditions. Their blood counts and organ functions need to meet specific levels, they should not be on seizure threshold-lowering meds for at least 4 weeks before the trial, and agree to use effective contraception.
What is being tested?
The trial is testing if ARN-509 works better alone or with abiraterone acetate, GnRH agonist, and prednisone in treating prostate cancer before surgery. The goal is to see if these treatments can reduce the amount of androgen since it helps prostate cancer cells grow.
What are the potential side effects?
Possible side effects include fatigue, hot flashes, joint pain, nausea, decreased appetite, constipation or diarrhea. There may also be an increased risk of infections due to lowered immune system function.

Experimental Treatment
Active Control
Group I: Arm I (androgen receptor ARN-509, radical prostatectomy)Experimental Treatment4 Interventions
Patients receive androgen receptor antagonist ARN-509 PO daily for 3 months. Patients then undergo radical prostatectomy.
Group II: Arm II (ARN-509, abiraterone acetate, GnRH, prednisone, RP)Active Control7 Interventions
Patients receive GnRH agonist SC on day 1, androgen receptor antagonist ARN-509 PO daily PO for 4 times, abiraterone acetate PO daily for 4 times, and prednisone PO daily for 3 months. Patients then undergo radical prostatectomy.
Group III: Arm III (radical prostatectomy)Active Control3 Interventions
Patients undergo radical prostatectomy.
