A Prospective Clinical Study on the Safety and Effectiveness of Tislelizumab Combined With Axitinib for Neoadjuvant Treatment of Clear Cell Renal Cell Carcinoma

This trial is a single-center clinical trial to evaluate the tumor shrinkage and safety of tislelizumab combined with axitinib in Neoadjuvant therapy of T2-T3N0M0 renal clear cell carcinoma

Study Overview

• Status: Active, not recruiting
• Conditions: Neoadjuvant Therapy
• Intervention / Treatment: Drug: tislelizumab combined with axitinib

Detailed Description

The goal of the study is to use axitinib combined with tislelizumab in the Neoadjuvant therapy of T2-T3 N0M0 renal clear cell carcinoma to shrink tumors or tumor thrombi, reduce the complexity of surgery, and achieve kidney Partial resection or enucleation of renal tumors instead of kidney Partial resection, or unresectable renal tumors can be changed to resectable and improve the patient's prognosis.

The primary endpoint is the tumor shrinkage effect of tislelizumab combined with axitinib in Neoadjuvant therapy of T2-T3N0M0 renal clear cell carcinoma.

The secondary end point is

• The safety and downgrading rate of tislelizumab combined with axitinib in Neoadjuvant therapy of T2-T3N0M0 renal clear cell carcinoma；
• Two-year disease-free survival (DFS) of tislelizumab combined with axitinib in Neoadjuvant therapy of T2-T3N0M0 renal clear cell carcinoma；
• Explore biomarkers in tumor tissue and blood that may be related to the efficacy of neoadjuvant therapy and the prognosis of subjects;
