Neoadjuvant PD-1 Monoclonal Antibody Plus Cisplatin-based Chemotherapy in Locally Advanced Upper Tract Urothelial Carcinoma

• Status: Active, not recruiting
• Trial end date: 2022-06-01
• Target enrollment: 0
• Participant gender: All

Summary

This study is designed prospectively to investigate the safety and efficacy of neoadjuvant PD-1 monoclonal antibody combined with cisplatin-based chemotherapy in patients with locally advanced upper urinary tract urothelial carcinoma (UTUC). Tislelizumab, an anti-programmed death protein-1 (PD-1) monoclonal antibody, was engineered to minimize binding to FcγR on macrophages to abrogate antibody-dependent phagocytosis, a mechanism of T-cell clearance and potential resistance to anti-PD-1 therapy. The safety, tolerability, and efficacy of tislelizumab in patients with PD-L1 positive urothelial carcinoma who progressed during/following platinum-containing therapy was proved in a phase 2 trial (CTR20170071). This trial focuses on the efficacy of Tislelizumab in combination with cisplatin-based chemotherapy to induce pathological down-staging of locally advanced UTUC in neoadjuvant setting.
