Abstract Purpose  To identify patients with metastatic urothelial cancer (mUC) unlikely to benefit from immune-checkpoint inhibitors (ICIs). Methods/Patients  We explored the predictive and prognostic values of baseline neutrophil-to-lymphocyte ratio (NLR), with cut-offs ≥ 3 and ≥ 5, and of a urothelial immune prognostic index (UIPI, based on increased NLR and LDH), on 146 patients. Results  NLR and UIPI significantly predicted progressive disease and progression-free survival with both cut-offs (p = 0.0069, p = 0.0034, p = 0.0160, p = 0.0063; p
