• Estimated survival ≥ 3 months.
• Pathologically confirmed urothelial carcinoma confirmed by imaging or other methods as locally advanced unresectable or metastatic disease.
• Patients with locally advanced or metastatic disease who have previously received both a platinum-based chemotherapy regimen and a PD-(L)1 inhibitor; patients who received platinum-based chemotherapy and/or a PD-(L)1 inhibitor as neoadjuvant or adjuvant therapy and experienced recurrence or progression during treatment or within 6 months after completing treatment will be considered to have received these therapies in the locally advanced/metastatic setting.
• Imaging-confirmed disease progression during or after treatment with the most recent regimen.
• Able to provide preserved or fresh tumor tissue.
• Must be present with at least one measurable lesion according to RECIST v1.1 criteria.
• Good level of organ function.
• Male subjects whose partners are women of childbearing potential and female subjects of childbearing potential must use highly effective contraception from the time of signing the informed consent form until 8 months after the last dose of the trial drug.

Критерии исключения

• Planned to receive any other anti-tumor therapy during this trial.
• Receipt of other unmarketed clinical trial drugs or treatments within 4 weeks prior to randomization.
• Received systemic anti-tumor therapy such as chemotherapy, radiotherapy, biological therapy, targeted therapy, or immunotherapy within 4 weeks prior to randomization, and palliative radiotherapy or local therapy within 2 weeks prior to the first use of the investigational drug.
• Prior receipt of antibody-drug conjugates containing topoisomerase I inhibitors in the composition.
• For locally advanced or metastatic disease: patients who have previously received more than three lines of systemic therapy in this setting.For neoadjuvant or adjuvant therapy: if the disease recurs or progresses during treatment or within 6 months after its completion, the patient is considered to have received first-line systemic therapy for locally advanced or metastatic disease.
• Prior treatment with more than 1 antibody-drug conjugate.
• Major surgery other than diagnosis or biopsy within 4 weeks prior to randomization that requires elective surgery during the trial.
• Received systemic glucocorticoids (prednisone > 10 mg/day or equivalent dose) or other immunosuppressants within 14 days prior to the first use of investigational drug or randomization for immunosuppressive purposes.
• Adverse events from prior antineoplastic therapy did not recover to Grade ≤1 according to NCI-CTCAE v5.0.
• Inadequately treated central nervous system (CNS) metastases, or the presence of uncontrolled or symptomatic active central nervous system metastases. CNS metastases that have been adequately treated and whose neurological symptoms are able to return to baseline at least 4 weeks prior to randomization (with the exception of residual signs or symptoms associated with CNS treatment) may be enrolled in the study.
• Subject has a serous effusion with clinical symptoms or requiring puncture and drainage.
• Any malignancy diagnosed within 5 years prior to randomization (calculated from the date of the last anti-tumor treatment), except:Localized, low-risk prostate cancer.Papillary thyroid carcinoma, basal-cell carcinoma, or squamous-cell carcinoma of the skin that has been adequately treated and shows no evidence of disease.Other carcinomas in situ that have been adequately treated and show no evidence of disease recurrence.
• History of interstitial pneumonitis/interstitial lung disease or non-infectious pneumonitis (e.g., radiation pneumonitis) that required systemic corticosteroid therapy.Current evidence, in the investigator's judgment, of uncontrolled interstitial pneumonitis/interstitial lung disease, non-infectious pneumonitis, or any other active pneumonitis.
• Severe infections requiring intravenous antibiotics, antivirals, or antifungals for control.
• Active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection.
• Has a history of immunodeficiency or organ transplantation.
• Any serious arterial or venous thrombotic event within 6 months before randomization.
