Fruquintinib and Serplulimab Combination Therapy for First-line Treatment of Non-clear Cell Renal Cell Carcinoma: A Prospective Multicenter Study
Study Details
Study Description
Brief Summary
This study is design to prospectively investigate the safety and efficacy of Fruquintinib combined with Serplulimab in first-line treatment of non-clear renal cell carcinoma. Fruquintinib, a vascular endothelial growth factor receptor inhibitor, is an anticancer drug independently developed in China to treat refractory metastatic colorectal cancer (mCRC). This is a Single-arm, multicenter, prospective phase 2 clinical study.

Phase 2 |
Detailed Description
The study is ongoing. This is a single-arm, multicenter clinical study enrolling 39 patients with metastatic or unresectable nccRCC at Renji Hospital and Zhongshan Hospital in Shanghai, China. The study is divided into a safety-run-in stage and a cohort expansion stage. Six patients were enrolled in the safety-run-in stage, and no dose-limited toxicity or treatment-related deaths occurred within the 28-day observation period. Consequently, the cohort was expanded to 39 patients. The treatment includes Fruquintinib 5mg, qd, 2w on/1w off, combined with Serplulimab 4.5mg/kg, IV drip, d1, q3w. Tumor response is evaluated at baseline, every 6 weeks during treatment, and at end-of-treatment visit.

-
Absolute neutrophil count (ANC) ≥1.5× 109/L;
-
Platelet count ≥100×109/L;
-
Hemoglobin ≥9g/dL;
-
Serum albumin ≥2.8g/dL;
-
Total bilirubin ≤1.5 ×ULN, ALT, AST, and/or ALP ≤3 ×ULN; if liver or bone metastasis is present, ALP ≤5 ×ULN;
-
Serum creatinine ≤1.5×ULN and creatinine clearance rate 60 mL/min (Cockcroft-Gault, see Appendix 3);
-
Activated partial thromboplastin time (APTT) and international normalized ratio (INR) ≤1.5× ULN (patients receiving stable doses of anticoagulant therapy such as low-molecular-weight heparin or warfarin and whose INR is within the expected therapeutic range of anticoagulants can be screened); 9) Patients infected with hepatitis B Virus (HBV) and inactive/asymptomatic carriers, or patients with chronic or active HBV will be allowed to enroll if their HBV DNA<500 IU/mL (or 2500 copies/mL); HCV antibody-positive patients will be allowed to enroll if HCV-RNA is negative during screening.
Note: HBsAg-positive patients or patients with detectable HBV DNA who receive antiviral treatment should undergo treatment for >2 weeks before enrollment, and continue treatment for 6 months after the study drug treatment.
- *For women of reproductive age, urine or serum pregnancy test results should be negative within 7 days or less before treatment. And use a medically approved contraceptive (such as an intrauterine device, contraceptive or condom) during the study treatment period and at least 3 months after the last use of Serplulimab and at least 6 months after the last use of chemotherapy; 11) Male subjects who are not sterilized must be willing to use a medically approved contraceptive method (such as an IUD, contraceptive or condom) for the duration of the study treatment, at least 3 months after the last use of Serplulimab and at least 6 months after the last use of chemotherapy.
Exclusion Criteria:
-
- There is a history of allergy to any component of the drug SLT or the drug Fruquintinib.
-

Other special circumstances should be communicated with the investigator. In the absence of active autoimmune diseases, inhaled or locally applied steroids and adrenal cortex hormones that replace a dosage of >10 mg/day prednisone can be used.
-
