Introduction: The central nervous system (CNS) is a common site of progression among patients with -rearranged lung cancer receiving crizotinib. We conducted a phase 2 study to evaluate the intracranial efficacy of lorlatinib in patients with -rearranged lung cancer who developed CNS-only progression on crizotinib.
Methods: Patients with metastatic -rearranged lung cancer with CNS-only progression on crizotinib received lorlatinib 100 mg daily.
