A drug used to treat non-small cell lung cancer that has spread to other parts of the body and is anaplastic lymphoma kinase (ALK) positive. It is used in patients whose cancer has gotten worse during treatment with or who cannot take crizotinib (a type of anticancer drug). Brigatinib blocks certain proteins made by the ALK gene. Blocking these proteins may stop the growth and spread of cancer cells. Brigatinib is a type of tyrosine kinase inhibitor. Also called Alunbrig.
