How might NEXAVAR work?

NEXAVAR may interfere with 2 signaling pathways in cancer cells and tumor blood vessels. NEXAVAR:

  • Inhibits tumor cell signals, decreasing cancer cell growth and division

  • May decrease the formation of new blood vessels that provide oxygen and nutrients needed for cancer cells to keep growing

By slowing tumor growth and reducing the blood supply to the tumor, NEXAVAR may prevent the growth and spread of cancer. These pathways can also be important to normal cells, so therapies like NEXAVAR may affect some normal cells as well.
