Abstract 5751
Background
The second-generation ALK tyrosine kinase inhibitor (TKI) ALC has demonstrated efficacy and acceptable safety in ALK+ NSCLC pts who have progressed on CRZ. However, resistance to ALC eventually develops, with secondary resistance mutations detected in approximately 50% of pts and a median progression-free survival (PFS) <1 year. BRG is a next-generation ALK TKI designed to have potent and broad activity against ALK mutants. Post-CRZ, BRG demonstrated high systemic and central nervous system (CNS) objective response rates (ORRs) and the longest reported median PFS of any ALK inhibitor in this setting (16.3–16.7 mo) (Huber. J Clin Oncol 2018;36; Bazhenova. Ann Oncol 2017;28). The current trial was designed to compare efficacy and safety of BRG vs ALC in pts with ALK+ NSCLC that has progressed on CRZ.
