Popis: The central nervous system (CNS) is a common site of progression among patients withPatients with metastaticA total of 16 patients were enrolled between November 2016 and January 2019. Nine patients (56%) had received prior CNS radiation, with a median of 10.9 months between radiation and lorlatinib. At 12 weeks, the intracranial disease control rate was 100% and intracranial objective response rate was 87%. While on study, the complee intracranial response rate was 60%. With median follow-up of 22 months, seven patients experienced disease progression, including five patients with CNS relapse. The median intracranial and extracranial progression-free survivals were 38.8 months (95% confidence interval: 16.9-not reported) and 41.1 months (95% confidence interval: 17.6-not reported), respectively. Molecular analysis of plasma or tissue from patients with extracranial progression on lorlatinib revealedLorlatinib induced durable intracranial responses in patients with
