Used primarily in the treatment of chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL) with Philadelphia chromosome, it works by inhibiting abnormal tyrosine kinase enzymes that drive uncontrolled cancer cell growth. Also effective in treating gastrointestinal stromal tumors (GIST) by targeting c-KIT and PDGFR kinase activity. Its targeted mechanism reduces damage to normal cells, making it a cornerstone of precision medicine in oncology. Administered orally, it has significantly improved survival rates in patients with these cancers.
