Five new PD-1/PD-L1 checkpoint inhibitors have been approved for the treatment of metastatic urothelial carcinoma (UC): pembrolizumab, atezolizumab, durvalumab, nivolumab, and avelumab. Although cisplatin-based chemotherapy remains the recommended frontline option for cisplatin-eligible patients with metastatic UC, immunotherapy is now an available option in the second-line setting as well as the frontline setting for selected cisplatin-ineligible patients who are either unable to tolerate chemotherapy or PD-L1–positive. This review describes the updated clinical efficacy of these checkpoint inhibitors in the treatment of advanced UC and suggests how they can be sequenced in the context of available chemotherapeutic options.
