Summary

A single-arm, prospective, exploratory clinical trial to explore the pathological complete response (pCR) rate of immune checkpoint inhibitors combined with antibody conjugate drugs as the perioperative treatment of platinum-intolerant bladder cancer patients. Fifty-five patients with clinically or pathologically confirmed muscle-invasive bladder urothelial carcinoma (MIBC) who were ineligible for cisplatin-based chemotherapy or refused cisplatin-based chemotherapy were enrolled. Each subject will receive RC48-ADC and toripalimab intravenously every 2 weeks for a total of 4 cycles before surgery, 8 cycles after surgery. The efficacy was evaluated and followed up after 4 cycles of neoadjuvant therapy, 3 months postoperative, and every 3-6 months thereafter. The primary endpoint of this study was pathological complete response rate (pCR). The secondary endpoints were to explore the safety, disease-free survival (DFS), overall survival (OS), objective response rate (ORR) and disease control rate (DCR) of RC48 combined with toripalimab neoadjuvant therapy followed by radical cystectomy.
