Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the efficacy and safety of intravenous RC48-ADC combined with JS001 in postoperative adjuvant therapy for HER2-positive upper tract urothelial carcinoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an open-label, single-arm clinical trial to evaluate the efficacy and safety of RC48-ADC, a recombinant humanized anti-HER2 monoclonal antibody-Monomethyl auristatin E (MMAE) conjugate, in combination with JS001, a PD-1 monoclonal antibody, for the postoperative adjuvant treatment of HER2-positive upper tract urothelial carcinoma after radical nephroureterectomy.
