RESUMEN
INTRODUCTION: Bladder cancer (BC) is the sixth most common type of cancer with epithelial/urothelial and non-urothelial origins. Urothelial carcinoma (UC) involves neoplastic cells of epithelial origin and accounts for 90% of all BC cases. Current review aims to discuss the latest advances and challenges in the treatment of UC with an emphasis on clinical pharmacology considerations. AREAS COVERED: Data including clinical efficacy and safety outcomes as well as precautions reported in published clinical studies obtained from PubMed and package inserts were collected and summarized in the review. Recent decade saw the approval of multiple drugs for the treatment of BC in both adjuvant/neoadjuvant setting as well as for unresectable tumors. Checkpoint blockers (pembrolizumab, nivolumab, atezolizumab, and avelumab), antibody drug conjugates (enfortumab vedotin and sacituzumab govitecan) and targeted therapies (erdafitinib) are now available in first-line (cisplatin-ineligible), second-line and third-line settings along with conventional platinum-based chemotherapy. While the survival outcomes have improved especially in refractory and unresponsive patients, the response rates are relatively low and patient safety needs further optimization. EXPERT OPINION: Additional studies on combination therapies, dose adjustments in special populations and impact of anti-drug antibodies on drug exposure are needed to further improve clinical outcomes.
