A drug used to treat non-small cell lung cancer that has spread to other parts of the body and has a mutated (changed) form of a gene called anaplastic lymphoma kinase (ALK). It is also being studied in the treatment of other types of cancer. Alectinib blocks certain proteins made by the mutated ALK gene. Blocking these proteins may stop the growth and spread of cancer cells. Alectinib is a type of tyrosine kinase inhibitor. Also called Alecensa.
