- Predicted survival = 12 weeks.

- Have histologically or cytologically-confirmed diagnosis of inoperable, locally advanced or metastatic urothelial cancer of the bladder, renal pelvis, ureter.

Outcome

Type Measure Description Time frame Safety issue
Primary Objective Response Rate (ORR) Objective Response Rate was defined as the percentage of participants with a complete response (CR) or partial response (PR) up to 24 months
Secondary ORR of HER2-positive patients Tumor response was assessed by investigator according to RECIST v1.1 up to 24 months
Secondary Progression Free Survival (PFS) Tumor response was assessed by investigator according to RECIST v1.1 up to 24 months
Secondary Duration of Response (DOR) DOR was defined as the time from first documented OR to first documented PD or death from any cause, whichever occurred earlier up to 24 months
Secondary Disease control rate (DCR) DCR was defined as the proportion of patients who achieved an objective response or maintained stable disease during the study up to 24 months
Secondary Overall Survival(OS) OS was defined as the time from the first study treatment to the date of death from any cause up to 24 months
Secondary Adverse Events Incidence of Adverse Events 28 days after the last dose of study treatment
