Summary

This is a prospective, open, single-center clinical study of anti-HER2-ADC combined with PD-1 monoclonal antibody for bladder sparing treatment in non-muscular invasive bladder cancer (NMIBC) patients with HER2-expressing. The study was conducted in accordance with the Good Clinical Practice (GCP). Approximately 20 subjects will be enrolled to evaluate the efficacy and safety of RC48 (RC48 2.0 mg/kg intravenously administered every two weeks) combined with Tislelizumab (Tislelizumab 200 mg intravenously administered every three weeks).

Subjects undergo Transurethral resection of bladder tumor (TURBT), imaging diagnosis and pre-treatment biological samples of blood, urine and biopsy tissue.

The study will include high-risk NMIBC patients who express HER2, fail after BCG treatment, but refuse to undergo cystectomy or do not meet the requirements for cystectomy.

Subjects will receive RC48 and Tislelizumab for two years. BI-DFS were evaluated by cystoscopy, histopathologic examination, laboratory examination, and imaging examination after treatment, and tumor efficacy was evaluated when clinical studies reached the number of subjects specified in the protocol for efficacy evaluation.
