Brief Summary:
To evaluate whether Fuzuloparib plus AA-P is superior to placebo plus AA-P as first-line treatment by assessment of radiographic progression-free survival (rPFS) in mCRPC subjects unselected for deoxyribonucleic acid (DNA) damage repair deficiencies (DRD) status (Cohort 1) to evaluate whether Fuzuloparib plus AA-P is superior to placebo plus AA-P as first-line treatment by assessment of rPFS in mCRPC subjects harboring DRD (Cohort 2).

Primary Outcome Measures :
  1. rPFS by blinded independent central review (BICR) using RESIST1.1 and PCWG3 [ Time Frame: up to 3 years ]
    progression-free survival


Secondary Outcome Measures :
  1. OS [ Time Frame: up to 4 years ]
    time from randomization to death due to any cause

  2. ORR [ Time Frame: up to 3 years ]
    The percentage of subjects with measureable disease at baseline who achieved a complete or partial response in their soft tissue disease using the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria

  3. Time to PSA progression [ Time Frame: up to 3 years ]
    Time from randomisation to the first time of PSA progression according to the criterion of PCGW3

  4. Time to skeletal-related events [ Time Frame: up to 4 years ]
    Time from randomisation to the first occurrence of a fracture or treatment for the fracture. The skeletal-related event is defined as the occurrence of either pathological or clinical fracture, spinal cord compression, bone-related radiotherapy or surgery.
