Early circulating tumor (ct) DNA dynamics and efficacy of lorlatinib: Analysis from the CROWN study.

Early ctDNA dynamics may predict lorlatinib efficacy in pts with previously untreated ALK-positive NSCLC. The magnitude of reduction in ctDNA at 4 weeks may be associated with better responses and potentially longer PFS. These findings further support the utility of dynamic ctDNA monitoring in ALK-positive NSCLC. READ ARTICLE
