Inclusion Criteria: * Written informed consent * Histologically confirmed TCCU (urinary bladder, urethra, ureter or renal pelvis). Patients with mixed histology may be enrolled if TCCU is the predominant component (i.e., \> 50% of the histopathology sample) with the exception of neuroendocrine or small cell carcinoma. * Advanced disease defined as a locally advanced tumour considered unresectable (T4b), node involvement in the inguinal area or above the aortic bifurcation (that are considered to be distant nodes and so metastasis) or metastasis in distant organs. * Patient should have received one prior platinum-based chemotherapy treatment for locally advanced or stage IV TCCU. Prior platinum-based adjuvant or neoadjuvant therapy is allowed if more than 6 months have elapsed since the end of adjuvant or neoadjuvant therapy till tumour relapse. * At least one measurable tumour lesion (measurable disease, as defined by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria v1.1 * ≥18 years. * ECOG PS 0 or 1. * May have no more than ONE of the following unfavourable risk factors: 1. haemoglobin \<10 g/dL 2. presence of liver metastasis 3.
