Who can join

Age: 18 and older. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• Subjects diagnosed with prostate cancer through preoperative transrectal prostate biopsy and pathological examination, who are scheduled to undergo radical prostatectomy with or without pelvic lymph node dissection;
• Subjects must provide informed consent prior to trial initiation, fully understand the trial content, procedures, and potential adverse reactions, be capable of effective communication with the investigator, and be able to complete the trial as per protocol requirements. They must voluntarily sign a written informed consent form;
• Adult male subjects aged 18 years or older (including the boundary value);
• Gleason score ≥7, or imaging studies (transrectal ultrasound [TRUS] and/or prostate magnetic resonance imaging [MRI] or CT or PSMA PET/CT) demonstrating disease staging ≥T2, or imaging evidence of regional lymph node enlargement suggestive of lymph node metastasis;
• No hepatic or renal impairment: Hepatic: Total bilirubin ≤ 2 times the upper limit of normal (ULN) (excluding Gilbert syndrome), alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤ 3×ULN; Renal: Creatinine clearance ≥ 50 mL/min/1.73 m² (simplified MDRD formula);
• The investigator determines the subject has no clear contraindications for surgery and is suitable for radical prostatectomy;
• The subject and their partner or spouse must agree to have no plans for pregnancy or sperm donation from the screening period until 3 months after trial completion, and voluntarily use effective contraception.

You may not qualify if…

• Subjects will be excluded if they meet any one of the following criteria:
• Subjects with a history of allergies (e.g., known allergies to two or more medications), those prone to allergic reactions such as rashes or hives, or those with known allergies to the investigational drug (including its formulation components);
• Subjects with significantly abnormal screening test results deemed clinically significant by the investigator and likely to affect study participation; or those with concomitant conditions posing serious safety risks or impeding study completion (except where the investigator determines the condition is stable and allows enrollment);
• Subjects who participated in another clinical trial involving investigational drugs or devices within the month preceding study drug administration;
• Subjects who have undergone neoadjuvant therapy, radiation therapy, focal ablation therapy, hormone therapy, or androgen deprivation therapy within the past 6 months;
• Subjects deemed by the investigator to have other conditions rendering them unsuitable for participation in this trial.
