Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE2
• Total Enrollment: 36 participants

Brief Summary

This study will evaluate the efficacy and safety of intravenous RC48-ADC combined with AK104 in perioperative treatment of muscle-invasive bladder cancer.

Detailed Description

36 patients with Muscle-invasive Bladder Cancer（MIBC） scheduled for radical cystectomy will participate in this study. The patient had not previously received any antitumor system therapy for MIBC. HER2 expression in MIBC patients is defined as the expression of HER2 in tumor tissues detected by immunohistochemistry (IHC) as IHC 1+, 2+, or 3+. After enrollment, the subjects will receive 4 cycles neoadjuvant therapy and 14 cycles adjuvant therapy.

Conditions

Muscle Invasive Bladder Carcinoma
