- Background
XL999 has the potential to provide benefit to patients with lung cancer and acute myelogenous leukemia. XL999 is a new chemical entity that inhibits a spectrum of receptor tyrosine kinases (RTKs) with growth promoting and angiogenic properties, including FGFR 1/3, PDGFRα/β, VEGFR2/KDR, KIT, and FLT3. XL999 also inhibits FLT4 and SRC. XL999 has the potential to prevent tumor growth — both directly by a novel effect on tumor cell proliferation and indirectly through inhibition of the host angiogenic response. XL999 induces a cell-cycle block by a mechanism distinct from those previously identified and exhibits broad antitumor activity in xenograft models.

- Mechanism of action
XL999 is a potent inhibitor of key receptor tyrosine kinases implicated in the development and maintenance of tumor vasculature and in the proliferation of some tumor cells. It inhibits FGFR1, FGFR3, RET, VEGFR2 and PDGFR, and is also a potent inhibitor of FLT3, an important driver of leukemia cell proliferation in some patients with acute myelogenous leukemia (AML). XL999 exhibited excellent activity in target-specific cellular functional assays.
