AZD2171

AZD2171, under development by AstraZeneca International, is an oral tyrosine kinase inhibitor of all of the VEGF receptors (VEGFR1, VEGFR2, VEGFR3), as well as KIT and (less potently) PDGFRA and PDGFRB. Vascular endothelial growth factor (VEGF) is a stimulus of angiogenesis (growth of new blood vessels), which is required to support solid tumor growth. VEGFR binds to transmembrane receptor Flt-1 (VEGF-1) and KDR (VEGF-2), resulting in subsequent propagation of intracellular signaling and angiogenesis.  With the exception of growth of the long bones during growth and cyclical changes in the female reproductive tissues, angiogenesis does not  occur in healthy adults.  Chronic inhibition of this process may therefore be tolerated and provide a means for achieving selective therapeutic intervention through prevention of tumor progression.

There is a Phase II international clinical trial of AZD2171 presently recruiting patients.  The purpose of the trial is to evaluate the biological activity of AZD2171 as measured by FDG-PET response in patients with metastatic GIST resistant or intolerant to imatinib (Gleevec).
