ACTR-33. INFIGRATINIB (BGJ398) IN PATIENTS WITH RECURRENT GLIOMAS WITH FIBROBLAST GROWTH FACTOR RECEPTOR (FGFR) ALTERATIONS: A MULTICENTER PHASE II STUDY

ABSTRACT: Abstract

INTRODUCTION

FGFR mutations and translocations occur in approximately 10% of glioblastomas (GBMs). FGFR3-TACC3 fusion is predictive of response to FGFR tyrosine kinase inhibitors pre-clinically and clinically. Infigratinib (BGJ398) is a selective small-molecule pan-FGFR kinase inhibitor with anti-tumor activity in several solid tumors with FGFR genetic alterations.

METHODS

Open-label phase II trial of adults with recurrent high-grade gliomas following failure of initial therapy (NCT01975701). Tumors harbored FGFR1-TACC1 or FGFR3-TACC3 fusions, activating mutations in FGFR1, 2 or 3, or FGFR1, 2, 3, or 4 amplification. Oral infigratinib was administered 125 mg d1–21 q28d. Prophylaxis for hyperphosphatemia was recommended. Primary endpoint: 6-month progression-free
