Targeted therapy is a type of cancer treatment that targets proteins in cancer cells that help the cancer grow, divide, and spread. Targeted therapy drugs identify these specific proteins and attack the cancer cells while trying to minimize damage to healthy cells.1
Avastin® (bevacizumab) is a targeted therapy drug used to treat some types of ovarian cancer.2
Following surgery for advanced epithelial ovarian cancer (stage III or IV), Avastin is used in combination with certain chemotherapy drugs. It is then followed by treatment with Avastin alone or with a PARP inhibitor.2
Avastin is also used with specific chemotherapy drugs to treat certain forms of recurrent platinum-resistant ovarian cancer and recurrent platinum-sensitive ovarian cancer.2
What are the ingredients in Avastin?
The active ingredient in Avastin is bevacizumab.3
How does Avastin work?
Avastin blocks a certain protein called vascular endothelial growth factor (VEGF). While healthy cells make some VEGF, some cancer cells make too much VEGF. Blocking VEGF may help to prevent new blood vessel growth, including blood vessels that provide nutrients tumors need to grow.4
By blocking VEGF, Avastin helps “starve” cancerous tumors, preventing them from growing and spreading.4
