Mechanism of action

Sorafenib inhibits both intracellular (RAF/MEK/ERK) and receptor tyrosine kinases (VEGFR-2, VEGFR-3, PDGFR-β) that are critical for tumor growth and blood vessel formation. By targeting these pathways, it reduces tumor cell proliferation and impairs the tumor's ability to develop new blood vessels (angiogenesis), thereby limiting nutrient supply to cancer cells.
