- Abstract: Metastatic bladder cancer has historically been treated with platinum-based chemotherapy as the standard firstline therapy. Since the introduction of cisplatin-based regimens, advancements in treatment strategies have been limited. However, the recent emergence of immune checkpoint inhibitors (ICIs) and antibody-drug conjugates (ADCs) has significantly transformed the treatment landscape. Notably, the combination of enfortumab vedotin (EV) and pembrolizumab has demonstrated considerable clinical benefits, challenging traditional chemotherapy. This review aims to provide an overview of recent advancements in the treatment of metastatic bladder cancer.Current Concepts: Recent phase III clinical trials, notably EV-302/KEYNOTE-A39 and CheckMate 901, have reshaped the first-line management. EV combined with pembrolizumab has shown superior progression-free survival and overall survival compared to platinum-based chemotherapy, establishing it as a new standard of care. Patients ineligible for this regimen due to underlying comorbidities or toxicity may still benefit from alternative options. Such alternatives include platinum-based chemotherapy with ICI maintenance therapy, including avelumab or nivolumab. The selection of treatments should be individualized, taking into account specific patient factors, particularly platinum eligibility, renal function, and performance status.Discussion and Conclusion: The incorporation of ICIs and ADCs into the therapeutic landscape for metastatic bladder cancer has significantly improved patient outcomes. EV plus pembrolizumab has demonstrated substantial survival benefits, establishing it as a preferred first-line regimen for eligible patients. However, not all patients are candidates for this combination, emphasizing the necessity of individualized treatment strategies. Future research should focus on managing treatment-related adverse events and developing personalized therapies to maximizing efficacy while minimizing toxicity.
