Yes, Gleevec (known generically as imatinib) is a targeted chemotherapy medication primarily used to treat certain types of cancers, most notably chronic myeloid leukemia (CML) and gastrointestinal stromal tumors (GISTs). Unlike traditional cytotoxic chemotherapy that attacks all rapidly dividing cells indiscriminately, Gleevec functions as a targeted therapy by specifically inhibiting abnormal tyrosine kinase enzymes that drive cancer cell proliferation.
