Prostate Biomarkers trial in metastatic hormone-sensitive prostate cancer (mHSPC) tests whether circulating tumor deoxyribonucleic acid (ctDNA) can personalize first-line treatment for mHSPC by safely de-escalating therapy in patients with undetectable ctDNA and by intensifying biomarker-matched treatment in ctDNA-detectable disease, aiming to preserve outcomes while reducing toxicity and improving quality of life.
