Crizotinib intermediate.

Crizotinib is a small molecule tyrosine kinase inhibitor (TKI) that targets anaplastic lymphoma kinase (ALK), ROS1, and another oncogene receptor tyrosine kinase MET. Crizotinib capsules can be used for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) patients who are positive for anaplastic lymphoma kinase (ALK) determined by the SFDA-approved test method. The approval of this indication is mainly based on the objective response rate (ORR) and progression-free survival (PFS) evidence. At present, there is no evidence of survival benefit (OS) of this product.
