FGFR and Biomarker Testing

Genetic alterations in FGFR are believed to influence urothelial carcinoma cell growth and proliferation1-3

Recent interest in the development of targeted therapies for advanced urothelial carcinoma is validated by data establishing that these cancers can harbor genetic alterations. Some of the most common alterations occur in the FGFR genes, particularly FGFR3.4-6

FGFR genetic alterations may cause constitutive signaling2,3

The interaction of altered F G F R on intracellular signaling pathways in a Urothelial Cancer Cell

Five blue human icons and one has a green double helix under it. About one in five patients with M I B C has F G F R alterations

An FDA-approved companion diagnostic test helps identify patients whose tumors have certain FGFR genetic alterations.8 The test detects certain clinically actionable FGFR genetic alterations from formalin-fixed paraffin-embedded urothelial tumor tissue.9

The approved companion diagnostic is available in various national and regional molecular pathology testing labs.

FDA = U.S. Food and Drug Administration; FGF = fibroblast growth factor; FGFR = fibroblast growth factor receptor; MIBC = muscle-invasive bladder cancer.
