A Study of MRG002 Versus Investigator's Choice of Chemotherapy in the Treatment of Patients With HER2-positive Unresectable Advanced or Metastatic Urothelial Cancer

Recruiting now · Phase 3

Conditions studied: Advanced or Metastatic Urothelium Cancer

In brief

The primary objective of this study is to compare the overall survival (OS) and progression-free survival (PFS) between MRG002 and investigator selected chemotherapy in patients with HER2-positive unresectable locally advanced or metastatic urothelial cancer previously treated with platinum-based chemotherapy and PD-1/PD-L1 inhibitors.

• Patients who have received ADC drugs, or prior taxane, gemcitabine, and pemetrexed for locally advanced or metastatic urothelial cancer; or have received investigational drugs from other clinical trials, chemotherapy, radiotherapy, targeted therapy, or immunotherapy within 4 weeks prior to the first dose; or have received Chinese medicine (herbal medicine) or Chinese patent medicine with anti-tumor indications within 2 weeks prior to the first dose; or have received strong CYP3A4 inhibitors within 2 weeks prior to the first dose or have current requirement of CYP3A4 inhibitors; or had major surgery within 4 weeks prior to the first dose without full recovery or planned surgery within 12 weeks after study treatment.
• Patients with clinical symptoms such as plural, abdominal or pericardial effusion requiring puncture drainage.
• Patients with central nervous system (CNS) metastasis and/or neoplastic meningitis.
