Overview
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.
Description
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.

- Pathological tissue immunohistochemistry HER2 2~3+
- Fit and willing to receive adjuvant therapy with first cycle to be commenced within 30 days of radical nephro-ureterectomy if allocated
