Translating the Therapeutic Potential of AZD4547 in <i>FGFR1</i> -Amplified Non–Small Cell Lung Cancer through the Use of Patient-Derived Tumor Xenograft Models

Abstract

This study provides novel epidemiologic data through identification of FGFR1 gene amplification in Chinese NSCLC specimens (particularly squamous) and, importantly, extends the clinical significance of this finding by using multiple FGFR1-amplified squamous lung cancer PDTX models to show tumor stasis or regression effects using a specific FGFR inhibitor (AZD4547). Thus, the translational science presented here provides a strong rationale for investigation of AZD4547 as a therapeutic option for patients with squamous NSCLC tumors harboring amplification of FGFR1.
