Brief Summary:
The study is being done to find out whether combining two FDA approved drugs along with radiation therapy for the treatment of high risk localized prostate cancer is safe and well tolerated.

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: Enzalutamide Drug: Leuprolide acetate Radiation: radiation Phase 2

Detailed Description:
  • this pilot study will assess the safety and tolerability of combining enzalutamide with an gonadotropin-releasing hormone agonist (GnRH) and external beam radiation
  • Correlative imaging and tissue biopsy analysis will be performed to assess the radiographic response to enzalutamide plus gonadotropin-releasing hormone agonist (GnRH) therapy as well as intratumoral androgen signaling

Arm Intervention/treatment
Enzalutamide, Leuprolide, radiation
Single arm Enzalutamide 160 mg daily for 6 months Leuprolide acetate 22.5mg every 3 months or 45mg every 6 months Radiation therapy as standard of care
Drug: Enzalutamide
160mg by mouth each day
Other Name: Xtandi

Drug: Leuprolide acetate
22.5 mg intramuscular every 3 months or 45mg intramuscular every 6 months
Other Name: Lupron

Radiation: radiation
External beam radiation will be delivered as per standard radiation therapy protocol

Primary Outcome Measures :
  1. Assess the safety and tolerability of combining enzalutamide with a GnRH and external beam radiation [ Time Frame: 12 months ]
    Assessment will be based on the rate of drug related grade 1-5 adverse events experienced within the first 12 months of study treatment via NCI Common terminology criteria for adverse events(CTCAE) v4.0

Secondary Outcome Measures :
  1. Assess intra-tumoral androgen regulated gene expression pre and post combination therapy [ Time Frame: 12 months ]
    tumor gene expression will be analyzed on tissue samples pre and post therapy
