Crizotinib

Crizotinib is a targeted cancer medication primarily used to treat certain types of lung cancer. It works by blocking specific abnormal proteins—called ALK and ROS1—that help cancer cells grow and spread. By inhibiting these proteins, crizotinib can slow or stop tumor growth, improving outcomes for patients with cancers harboring these genetic changes. It is taken orally as a tablet and is often part of personalized treatment plans based on specific genetic testing of the tumor.
