Neoadjuvant Immunotherapy of Cisplatin-ineligible High Risk Upper Urinary Tract Urothelial Carcinoma

Keywords

neoadjuvant therapy, radical nephroureterectomy, Tislelizumab, Cisplatin-ineligible

Brief summary

Neoadjuvant therapy of cisplatin-based chemotherapy has been proved to improve prognosis of muscle invasive UTUC patients in several studies. This study is designed to investigate the safety and efficacy of neoadjuvant PD-1 monoclonal antibody in patients with locally advanced upper urinary tract urothelial carcinoma (UTUC) which are ineligible for cisplatin. 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 to induce pathological down-staging of locally advanced UTUC in neoadjuvant setting.
