Mechanism

Alectinib is a small molecule inhibitor of anaplastic lymphoma kinase (ALK). It is effective in patients whose non-small cell lung cancer (NSCLC) harbors ALK mutations, including those who have progressed on or become intolerant to first-generation ALK inhibitors.

Indications

ALK-positive advanced non-small cell lung cancer in adultsFirst-line treatment of adults with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancerlung NSCLC (ALK translocation)advanced or recurrent NSCLC harboring the ALK fusion geneALK+ NSCLC who have progressed on treatment with crizotinib or are intolerant to crizotinibfirst-line treatment of ALK-positive advanced NSCLC
