• Male adult subjects aged 18 years or older (inclusive).
• Gleason total score ≥7, or radiological findings (transrectal ultrasound (TRUS) and/or prostate magnetic resonance imaging (MRI), computed tomography (CT) or prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT)) indicating clinical stage ≥T2.
• No hepatic or renal impairment: Hepatic function: Total bilirubin ≤2 × upper limit of normal (ULN) (except for Gilbert's syndrome), alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤3 × ULN; Renal function: Creatinine clearance rate ≥50 mL/min/1.73 m² (calculated via the simplified MDRD equation).
• Subjects judged by the investigator to have no definite surgical contraindications and to be suitable for robot-assisted radical prostatectomy (RARP).
• Subjects and their partners/spouses must agree to have no childbearing or sperm donation plans from the screening period to 3 months after the trial completion, and voluntarily adopt effective contraceptive measures.

Exclusion Criteria:

• Subjects with an allergic diathesis (e.g., a known history of hypersensitivity to two or more drugs), a predisposition to allergic symptoms such as rashes or urticaria, or a known hypersensitivity to the study drug (including its ingredients).
