  Purpose
This research study is evaluating a drug called enzalutamide in combination with external beam radiation therapy as a possible treatment for prostate cancer. Presently, when participants receive hormonal therapy with radiation therapy for prostate cancer, medications are given to reduce testosterone levels in the blood stream. This leads to side effects such as loss of sex drive, erectile dysfunction (ED) and decrease in muscle strength. The purpose of this study is test another form of hormonal therapy with radiationtherapy. The medication called enzalutamide will be used with radiation therapy. Instead of lowering testosterone, enzalutamide blocks testosterone in cells. This study will test if enzalutamide when used with radiation will lower the PSA without causing the side effects associated with medications that lower testosterone in the blood stream

Primary Outcome Measures:
  • Number of patients with more or equal 80% reduction of baseline PSA [ Time Frame: 25 week after treatment ]

Estimated Enrollment: 70
Anticipated Study Start Date: June 2017
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: June 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Enzalutamide with External
On this study patients will be treated with 6 months of Xtandi (enzalutamide). Approximately one-third of the way through this treatment they will receive EBRT. Starting on Day 1, all patients will ingestenzalutamide 160 mg/day at the same time each day without breaks (except as outlined for toxicity), with or without food, for 6 (28 day +/-3 days) cycles. Dose reduction of enzalutamide to 120 mg/day is allowed with the approval of the Medical Monitor. Patients will be instructed to return all unused capsules at each study visit to assess compliance and will receive study drug every 28 days (+/-3 days) for 6 cycles (25 weeks).
Drug: Enzalutamide

Radiation: External Beam Radiation Dose will be normalized such that exactly 98% of the PTV (planned target volume) receives the prescription dose and will be scored as per protocol. The maximum allowable dose within the PTV is 107% of the prescribed dose to a volume that is at least 0.03 cc. The minimum allowable dose within the PTV is >95% of the prescribed dose to a volume that is at least 0.03 cc.

EBRT shall receive prescription doses to the PTV 70 Gy delivered in 2.5 Gy

Other Name: XTANDI

Detailed Description:

The participant will be given a study drug-dosing diary for each of 6 treatment cycles. Each treatment cycle lasts 28 days (4 weeks), during which time the participant will be taking the study drug enzalutamide by mouth (4 pills daily). The diary will also include special instructions for taking the enzalutamide.

The participant will also be undergoing external beam radiation therapy during the study, for a duration of 5,5 weeks. Treatment will be administered on an outpatient basis. This part of the study is considered standard of care.

The participant will be required to have IGRT either by ConeBeam CT study and/or fiducial markers placed within the prostate as part of this study. These are very small gold markers that are placed in the prostate. This procedure is similar to the biopsy that the participant had to diagnose their cancer. These both procedures are routinely performed to permit imaging and position corrections to improve the precision of the external beam (radiation) delivery (Image Guided Radiation Therapy). This is also considered standard of care and is not experimental.

Planned Follow-up: Participants will be followed on study at a 3 month follow-up after treatment (cessation of enzalutamide). Additional follow-up to assess the status of the participant's cancer will be conducted at the discretion of the treating physicians as part of the participant's routine medical care.

  • To be able to swallow the medication of the study and to fulfill the requirements of the same one

Exclusion Criteria:

  • Received an investigational agent within 4 weeks prior to enrollment

  • Receiving concurrent androgens, anti-androgens, estrogens, or progestational agents, or received any of these agents within the 6 months prior to enrollment or having taken finasteride or dutasteride within 30 days of registration.
  • History of another active malignancy within the previous 5 years other than curatively treated nonmelanomatous skin cancer and superficial bladder cancer. Participants treated for malignancy with no relapse within two years are eligible to participate in the study.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection. Severe concurrent disease, infection, or co-morbidity that, in the judgment of the Investigator, would make the patient inappropriate for enrollment.

    2. Uncontrolled angina within 3 months of enrollment
    3. Congestive heart failure New York Heart Association (NYHA) class 3 or 4, or history of congestive heart failure NYHA class 3 or 4 in the past, unless a screening echocardiogram or multi-gated acquisition scan performed within 3 months results in a left ventricular ejection fraction ≥ 45%;
