ADT and SBRT vs SBRT Alone for Unfavorable Intermediate Risk Prostate Cancer

For this proposed Phase III study, unfavorable intermediate risk prostate cancer patients will be randomized to receive 6 months of Androgen Deprivation Therapy (ADT) in conjunction with stereotactic body radiation therapy/radiosurgery (SBRT) directed to the prostate versus SBRT alone. The patient population will include those with National Comprehensive Cancer Network (NCCN)-defined unfavorable intermediate risk disease. All patients will be followed every 6 months for up to 5 years from the first patient randomized and will undergo a routine 24-30 months post-SBRT prostate biopsy to assess for local tumor control.
