• Intravesical therapies like cretostimogene and TAR-200 show promising complete response rates in BCG-unresponsive NMIBC, but duration of response remains a key factor.
• Perioperative systemic therapies, including neoadjuvant chemo-immunotherapy with durvalumab, aim to improve event-free and overall survival in muscle-invasive urothelial carcinoma.
• Antibody-drug conjugates (ADCs) targeting Nectin-4 and HER2, such as enfortumab vedotin and disitamab vedotin, demonstrate significant potential in metastatic urothelial cancer.
• Novel strategies, including dual-targeting antibodies and combinations of ADCs with immunotherapies, are being explored to further enhance treatment efficacy and overcome resistance.
