Description

Imatinib (GLEEVEC®) is a tyrosine kinase inhibitor and antineoplastic agent that inhibits the BCR-ABL tyrosine kinase, the constitutive abnormal tyrosine kinase created by the Philadelphia chromosome abnormality in chronic myeloid leukaemia (CML). It inhibits proliferation and induces apoptosis in BCR-ABL positive cell lines as well as fresh leukemic cells from Philadelphia chromosome positive CML. Imatinib (GLEEVEC®) inhibits colony formation in assays using ex vivo peripheral blood and bone marrow samples from CML patients. It is also an inhibitor of the receptor tyrosine kinases for platelet-derived growth factor (PDGF) and stem cell factor (SCF), c-kit, and inhibits PDGF- and SCF-mediated cellular events. In vitro, imatinib (GLEEVEC®) inhibits proliferation and induces apoptosis in gastrointestinal stromal tumor (GIST) cells, which express an activating c-kit mutation.

Sample Use Guides

In Vivo Use Guide

The prescribed dose should be administered orally, with a meal and a large glass of water. Doses of 400 mg or 600 mg should be administered once daily, whereas a dose of 800 mg should be administered as 400 mg twice a day. Treatment may be continued as long as there is no evidence of progressive disease or unacceptable toxicity.

Route of Administration: Oral

In Vitro Use Guide

Imatinib (CGP 57148) was tested for growth inhibition of EGF-dependent BALB/MK cells, the H-ras-transformed T24 bladder carcinoma line, and IL-3-dependent growth of FDC-Pl cells. The compound showed only weak antiproliferative activity against these cell lines, with IC50 values of 12.7 uM, 9.4 uM, and 29.2 uM, respectively. However, when tested on v-abl-transformed PB-3c cells, incubation with CGP 57148 resulted in potent growth inhibition even in the presence of exogenous IL-3 (IC50 values, 0.11 uM without IL-3 and 0.9 uM with IL-3). Similar results were obtained using v-sis-transformed BALB/c 3T3 cells, which grow in response to autocrine PDGF production (IC50, 0.33 uM).
