Brigatinib: First Global Approval

Brigatinib (ALUNBRIG (TM)) is a small molecule antineoplastic anaplastic lymphoma kinase (ALK) inhibitor being developed by ARIAD Pharmaceuticals (a wholly-owned subsidiary of Takeda Pharmaceutical Company). In April 2017 brigatinib received accelerated approval in the USA for the treatment of patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to crizotinib. The development of resistance to crizotinib is a therapeutic challenge that has led to the development of second-generation ALK-inhibitors such as brigatinib, which have activity against treatment-resistant ALK mutants. This article summarizes the milestones in the development of brigatinib leading to this first global approval for the treatment of patients with ALK-positive metastatic NSCLC who have progressed on or are intolerant to crizotinib.
