Herceptin (chemical name: trastuzumab) works against HER2-positive breast
cancers by blocking the ability of the cancer cells to receive chemical
signals that tell the cells to grow.
Tykerb
Tykerb (chemical name: lapatinib) works against HER2-positive breast cancers
by blocking certain proteins that can cause uncontrolled cell growth.
Avastin
Avastin (chemical name: bevacizumab) works by blocking the growth of new
blood vessels that cancer cells depend on to grow and function. On Nov. 18,
2011, the U.S. Food and Drug Administration announced that it had removed
the breast cancer indication from Avastin because the drug has not been
shown to be safe and effective for that use. The medicine itself is not
being removed from the market and doctors can choose to use Avastin to treat
metastatic breast cancer whether or not that particular use is officially
approved by the FDA.
Perjeta
Like Herceptin, Perjeta (chemical name: pertuzumab) works against HER2-
positive breast cancers by blocking the cancer cells’ ability to receive
growth signals.
Afinitor
Afinitor (chemical name: everolimus) is an mTOR (mammalian target of
rapamycin) inhibitor. Afinitor works against hormone-receptor-positive
breast cancers that have stopped responding to Arimidex or Femara by
stopping the cancer cells from getting the energy they need. |
