Carcinoma, Transitional Cell, HER-2 Gene Amplification
Conditions
Brief summary
A open-label, single-arm, phase II trial to study was designed to evaluate the effectiveness and safety of trastuzumab and pyrotinib in treating HER2 positive patients who have previously treated, locally advanced, or metastatic urothelial carcinoma.
Interventions
DRUGTrastuzumab
A loading dose of trastuzumab 8mg/kg IV over 90 minutes will be administrated on day 1 of week 1. For all subsequent doses, trastuzumab 6mg/kg IV over 30 minutes will be administrated every three weeks. Pyrotinib 400mg PO daily will be administrated at the same time.
