1199P Dose modification for the management of CNS adverse events in the phase III CROWN study of lorlatinib in non-small cell lung cancer (NSCLC)

In the ongoing phase III CROWN study (NCT03052608), lorlatinib, a 3rd-generation inhibitor of anaplastic lymphoma kinase (ALK), improved progression-free survival (PFS) and intracranial response rates vs crizotinib in patients with previously untreated ALK-positive NSCLC. Here we present data on lorlatinib dose modification for the management of CNS adverse events (AEs). CNS AEs spontaneously resolved in 53% of cases, and lorlatinib dose modification was effective in managing CNS AEs without compromising efficacy. READ ARTICLE
