Lorlatinib, a third-generation anaplastic lymphoma kinase (ALK) inhibitor, causes distinct adverse events (AEs), including hyperlipidemia and central nervous system (CNS) disorders. Although dose modifications are recommended to manage these AEs, whether dose modifications can achieve optimal blood lorlatinib concentrations and reduce the incidence of lorlatinib-induced AEs remains unclear. Therefore, we investigated the association between lorlatinib exposure and AEs in each patient.
