    Immunotherapy provides a second-line option for patients with metastatic urothelial carcinoma (mUC) who have failed standard treatment, but biomarkers that predict the response of mUC patients to immunotherapy remain to be explored


    This study aims to evaluate the safety, efficacy and related biomarkers of toripalimab in mUC patients who have previously received treatment


    The recruited mUC patients received torepalizumab 3 mg/kg Q2W treatment

    The objective response rate of patients with PD-L1 positive and high TMB value (≥10 mutations/Mb) was significantly higher than that of PD-L1 negative patients (42% vs 17%; p=0.
