Summary

This study is an open label, single arm, multicenter clinical trial. The aim of this study is to evaluate the efficacy, safety, and quality of life of radiotherapy combined with Fuzuloparib and Abiraterone Acetate Tablets（Ⅱ） as first-line treatment for castration resistant prostate cancer patients. The study aims to enroll 40 eligible subjects with PSA response rate (PSA 50) as the primary endpoint.

2. ECOG score is 0 or 1
3. Untreated first-line metastatic castration resistant prostate cancer patients
4. Allow the use of a new endocrine drug treatment once during hormone sensitive stages
5. The organ function level must meet the following requirements (no blood transfusion or hematopoietic growth factor therapy received within 2 weeks before blood routine screening): ANC ≥ 1.5 × 109/L PLT≥100×109/L； • Hb≥90 g/L； • TBIL ≤ 1.5 × ULN (excluding subjects with Gilbert syndrome) • ALT and AST ≤ 2.5 × ULN; • Cr≤1.5×ULN； • LVEF≥50%； • QTcF≤450 ms。
6. If the partner is a subject with fertility, they should undergo surgical sterilization or agree to receive it during and at the end of the trial period
7. Sign a written informed consent form and expect good compliance with the research protocol

Exclusion Criteria:

1. Previously received any PARPi treatment for prostate cancer (including but not limited to Olaparib, Nilaparib, Terazopanib, Lucaparib, etc.)

5. Active heart disease within the first 6 months of randomization, including severe/unstable angina, myocardial infarction, symptomatic congestive heart failure (heart function class III or IV), and drug-induced ventricular arrhythmias
6. Individuals with active HBV and HCV infection (HBsAg positive and virus copy number ≥ 500 IU/mL, HCV antibody positive and HCV RNA above the detection limit of the analytical method)
7. Individuals with a known history of allergies to Fluzopanib and Abiraterone nanocrystals and their components
8. Individuals with a history of congenital immunodeficiency or organ transplantation, or HIV positive subjects who meet one or more of the following criteria: Not receiving highly effective antiretroviral therapy; Change antiretroviral therapy within 6 months prior to the start of screening; • Undertaking antiretroviral therapy that may interfere with the investigational drug (please consult the sponsor before enrollment); CD4 count\<350/mm3 during screening; Opportunistic infections that meet the definition of acquired immunodeficiency syndrome occurred within the 12 months prior to the start of screening
9. Patients with other malignant tumors within the past 3 years prior to randomization (excluding in situ cancer that has completely resolved and malignant tumors judged by researchers to have slow progression)
10. The researchers determined that participants with ejaculation ability and sexual activity were unwilling to take the contraceptive measures specified in the protocol during the entire study treatment period and within 3 months after the last dose
