Chemotherapy Combined With Tislelizumab as Bladder Sparing Option for Patients With Muscle Invasive Bladder Cancer

Muscle-Invasive Bladder Carcinoma Clinical Trial

Official title:
A Prospective, Single Center Clinical Study to Examine Cisplatin-based Chemotherapy Combined With Tislelizumab as Bladder Sparing Treatment for Patients With Muscle Invasive Bladder Cancer

Clinical Trial Summary

This study is designed prospectively to investigate the safety, efficacy and feasibility of cisplatin-based chemotherapy combined with tislelizumab as bladder sparing treatment for patients with muscle invasive bladder cancer (MIBC) which are eligible for cisplatin. The patients that achieved clinical remission after 4 cycles of cisplatin/gemcitabine and tislelizumab, will receive tislelizumab maintenance therapy for a year or 13 cycles. 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 investigates the efficacy of cisplatin-based chemotherapy combined with Tislelizumab to induce clinical complete remission of muscle invasive bladder cancer and the feasibility to provide bladder sparing treatment for these patients.

Clinical Trial Description

The patients that meet the Inclusion and Exclusion Criteria will treat with 4 cycles of cisplatin-based chemotherapy combined with Tislelizumab (200mg per cycle) prior to cystectomy discussion. The patients that show clinical benefit will receive tislelizumab for bladder sparing. Forty patients will be enrolled in this trial. ;
