Alectinib provides a new option for ALK-positive NSCLC patients after progression on crizotinib

In December 2015, alectinib became the third ALK inhibitor approved by the United States Food and Drug Administration for the treatment of non-small-cell lung cancer (NSCLC) that displays rearrangements of the anaplastic lymphoma kinase (ALK) gene. Alectinib is a second-generation small molecule inhibitor of the ALK protein that joins ceritinib in providing a useful treatment option for patients who have progressed on crizotinib, as a result of its ability to target crizotinib-resistant mutant forms of the ALK protein. Alectinib also displays enhanced penetrance of the blood-brain barrier, which improves efficacy against central nervous system (CNS) metastases.
