Spots Global Cancer Trial Database for Enzalutamide + External Beam Rt For Prostate

Study Description

Brief Summary: 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 radiation therapy. 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.

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 8 ½-10 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 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. This procedure is routinely performed to permit imaging and position corrections to improve the precision of the external beam (radiation) delivery (Image Guided Radiation Therapy). The placement of the three gold markers is performed by an Urologist. The fiducials are placed under ultrasound guidance. 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.
