Brief Summary:
The aim of this study is to compare the safety and efficacy of SHR3680 with bicalutamide in the treatment of patients with hormone sensitive prostate cancer.

Condition or disease Intervention/treatment Phase
Prostate Cancer Hormone-Dependent Prostate Cancer Drug: SHR3680 Drug: Bicalutamide Phase 3

Detailed Description:
This is an open, multicenter, randomized phase III trial. This clinical study compares the efficacy and safety of SHR3680 with bicalutamide in the patients with hormone sensitive prostate cancer. Approximately 572 patients who meet the entry criteria will be randomly assigned in a 1:1 ratio to SHR3680 or bicalutamide treatment. Primary endpoints of the study are radiological progress-free survival (rPFS) and overall survival (OS).

Arm Intervention/treatment
Experimental: SHR3680
Participants will receive SHR3680 orally
Drug: SHR3680
Tablet. Specifications of 80 mg; orally, once a day

Active Comparator: bicalutamide
Participants will receive bicalutamide orally
Drug: Bicalutamide
Tablet. Specifications of 50 mg; orally, once a day

Primary Outcome Measures :
  1. rPFS [ Time Frame: Approximately 70 months ]
    Time from randomisation to radiologically confirmed progressive disease or death due to any cause

  2. OS [ Time Frame: Approximately 70 months ]
    Time from randomisation to death due to any cause

Secondary Outcome Measures :
  1. Time to prostate specific antigen (PSA) progression [ Time Frame: Approximately 70 months ]
    Time from randomisation to the first time of PSA progression according to the criterion of PCGW3

  2. Time to skeletal-related events [ Time Frame: Approximately 70 months ]
    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

  3. Objective response rate (ORR) [ Time Frame: Approximately 70 months ]
    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

  4. Time to initiation of a new antineoplastic therapy [ Time Frame: Approximately 70 months ]
    Time from randomisation to the initiation of antineoplastic subsequent to the study treatment

  • Evidence of brain metastasis or primary tumors;
  • Planned to initiate any other anti-tumor therapies during the study;
  • Unable to swallow, chronic diarrhea and intestinal obstruction, or the presence of a variety of other factors that affect drug use and absorption; Clinically significant cardiovascular diseases;
  • History of seizure or certain conditions that may predispose to seizure;
  • Severe concurrent disease and infection that, in the judgment of the investigator, would make the patient inappropriate for enrollment.
