Predictive Value of Minimal Residual Disease for Efficacy of Toripalimab in High-risk Recurrent Renal Cell Carcinoma Following Nephrectomy: A Prospective Single-arm Study

This is a prospective cohort study aimed at clarifying the predictive value of MRD for postoperative DFS and OS in high-risk recurrent renal cell carcinoma patients who have undergone radical nephrectomy and received adjuvant treatment with Toripalimab. Further differentiating patients who need adjuvant immunotherapy.

There must be a histological diagnosis of renal cell carcinoma, with or without sarcomatoid features of clear cell components; On the day of signing the informed consent form, both males and females must be at least 18 years old; The participants provide written informed consent for the trial before enrollment; Have high risk or M1 NED renal cell carcinoma as defined by the following pathological tumor-node-metastasis and Fuhrman grading status; High risk RCC; pT4, Any Gr. N0, M0; pT Any stage, Any Gr., N+, M0; M1 NED RCC (participants who present not only with the primary kidney tumor but also solid, isolated, soft tissue metastases that can be completely resected at the time of nephrectomy); No previous systemic treatment for advanced RCC (except nephrectomy or pyelectomy) has been performed; Radical nephrectomy (and complete resection of metastatic lesions in M1 NED participants) was performed with a negative surgical margin; It must be evaluated by the investigator as tumor-free and verified by imaging such as CT or MRI. No suspicious brain metastases; Have an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 or 1; Non-surgical sterilization or female participants of childbearing potential who are required to use a medically approved contraceptive method (such as an IUD, contraceptive pill or condom) during the study treatment period and for 3 months after the end of the study treatment period; Serum or urine HCG tests must be negative for women of non-surgical sterilization or childbearing age within 7 days prior to study enrollment; And must be non-lactation period; Non-surgical sterilization or male patients of childbearing age who consent to use a medically approved contraceptive method with their spouse during the study treatment period and for 3 months after the end of the study treatment period; Vital organ function meets the following requirements (excluding use of any blood components and cell growth factors within 14 days) : normal bone marrow reserve function; Absolute neutrophil count (ANC)≥1500/µL, Platelets≥100 000/µL, Hemoglobin ≥5.6 mmol/L (9g/dL); Normal renal function or serum creatinine ≤1.5 mg/d and/or creatinine clearance ≥30 mL/min for participants with creatinine levels \>1.5×institutional ULN; Normal liver function or Total bilirubin ≤1.5xULN, or direct bilirubin≤ULN for participants with total bilirubin levels \>1.5×ULN; AST (SGOT) and ALT (SGPT) ≤2.5×ULN; International normalized ratio (INR) or prothrombin time (PT) ≤1.5×ULN.
