Targeting the FGFR Pathway in Urothelial Carcinoma: the Future Is Now.

🤖 Plain-English Summary

As we come to better understand cancer genomics, we are increasingly shifting towards precision medicine. In this review, we summarize the clinical data supporting FGFR inhibition, ways to optimize its use in routine clinical practice including FGFR testing, dosing, and toxicity management.

🔑 Key Findings

• FGFR has been elucidated as one of the oncogenic driver pathways in urothelial carcinoma, leading to exciting targeted drug development.
• Although many agents are being investigated, erdafitinib is the only FGFR inhibitor currently approved by the FDA for treating platinum-refractory metastatic urothelial carcinoma harboring susceptible FGFR2/3 alterations, with seemingly higher response rates than second-line chemotherapy or immunotherapy.
• In this review, we summarize the clinical data supporting FGFR inhibition, ways to optimize its use in routine clinical practice including FGFR testing, dosing, and toxicity management.
