Abstract LB043: Efficacy of Lorlatinib in Treatment-Naïve Patients (pts) With ALK-Positive Advanced Non-Small Cell Lung Cancer (NSCLC) in Relation to EML4-ALK Variant Type and ALK Mutations

Pts with untreated ALK+ advanced NSCLC had higher ORRs and potentially longer DOR and PFS across predefined biomarker subgroups when treated with lorlatinib compared with crizotinib in a phase 3 CROWN study. Based on pretreatment cfDNA analysis, lorlatinib led to similar clinical benefit regardless of the type of EML4-ALK variant or presence of ALK kinase mutations. READ ARTICLE
