Phase III ALTA-3 study of brigatinib (BRG) vs alectinib (ALC) in patients (pts) with advanced anaplastic lymphoma kinase (ALK)−positive non–small cell lung cancer (NSCLC) that progressed on crizotinib (CRZ)

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) Trial design The second-generation ALK tyrosine kinase inhibitor (TKI) ALC has demonstrated efficacy and acceptable safety in ALK+ NSCLC pts who have progressed on CRZ.
