Comparing a 6-month vs Long-term Course of Rezvilutamide With ADT Plus Chemotherapy in mHSPC

Primary Objective: To explore whether a 6-month course of Rezvilutamide in the triple therapy regimen is non-inferior to long-term Rezvilutamide treatment in improving radiographic progression-free survival (rPFS) in patients with high tumor burden metastatic hormone-sensitive prostate cancer (mHSPC). Secondary Objectives: To evaluate and compare the time to prostate-specific antigen (PSA) progression, time to next bone-related event, time to initiation of subsequent anti-prostate cancer treatment, and objective response rate (ORR) between the 6-month and long-term course of Rezvilutamide with androgen deprivation therapy (ADT) plus docetaxel in patients with high tumor burden mHSPC. To assess and compare the incidence of adverse events between the 6-month and long-term course of Rezvilutamide with ADT plus docetaxel in patients with high tumor burden mHSPC. Exploratory Objectives: To observe the circulating tumor cell status at 6 months, 12 months, 18 months, and 24 months in patients with high tumor burden mHSPC receiving the triple therapy regimen.
