Xalkori is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat metastatic non-small cell lung cancer (NSCLC) with tumors that are positive for anaplastic lymphoma kinase (ALK) as detected by an FDA-approved test. Xalkori is also known by its drug name, crizotinib.
Xalkori is a member of a class of drugs called tyrosine kinase inhibitors. Xalkori is believed to work by inhibiting the mutated version of the ALK kinase (protein), which is involved in the proliferation of cancer cells. This inhibition slows the growth of tumors.
