Parallel Phase III Randomized Trials of Genomic-Risk Stratified Unfavorable Intermediate Risk Prostate Cancer: De-Intensification And Intensification Clinical Trial Evaluation (GUIDANCE)

The de-intensification arm is designed to determine whether those with a low decipher genomic risk score (defined as less than 0.40) treated with radiation therapy alone instead of 6 months androgen deprivation therapy experience non-inferior rates of distant metastasis. The intensification arm aims to determine whether those in the high decipher genomic risk score (grater than or equal to .40) will have a superior metastasis-free survival through the addition of darolutamide with the standard radiation therapy and androgen deprivation therapy.
