Intracranial remission with brigatinib rechallenge as fifth-line ALK inhibition therapy in a lung cancer patient

Several anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors have been developed for the treatment of EML4-ALK-rearranged non-small-cell lung cancer, with the newer generation agents brigatinib, alectinib and lorlatinib showing pronounced central nervous system activities. Intracranial efficacy is an important feature for these agents, as metastatic lesions frequently occur in the central nervous system in the ALK-positive setting. Here, we report on an updated case of a patient who received her diagnosis in 2005 and has had disease progression with new lesions on six occasions over the last 8 years. During the first two progressions, only local recurrence was observed. After that, the lungs stayed clear and the patient progressed exclusively in the brain and spinal cord. Initial treatments consisted of chemotherapy and radiotherapy. In 2012, ALK-directed targeted therapy became available, and crizotinib was administered. The treatment was switched to brigatinib 3 years later be..... READ ARTICLE
