What is Avastin?

Avastin injection is used in combination with other chemotherapy medications to treat certain types of colon and rectal cancer (cancer that begins in the large intestine), non-small cell lung cancer (NSCLC), glioblastoma (a certain type of cancerous brain tumor), renal cell cancer (RCC, a type of cancer that begins in the kidney), cervical cancer (cancer that begins in the opening of the uterus [womb]), and ovarian (female reproductive organs where eggs are formed), fallopian tube (tube that transports eggs released by the ovaries to the uterus), or peritoneal (layer of tissue that lines the abdomen) cancer.

Avastin is also used in combination with atezolizumab (Tecentriq) to treat hepatocellular carcinoma (HCC) that has spread or cannot be removed by surgery in people who have not previously received chemotherapy.

Avastin belongs to a class of medications called antiangiogenic agents. Bevacizumab works by stopping the formation of blood vessels that bring oxygen and nutrients to tumors. This may slow the growth and spread of tumors.

Warnings

Avastin can make it easier for you to bleed. Seek emergency medical attention if you have any bleeding that will not stop. You may also have bleeding on the inside of your body.

Call your doctor if you have: signs of bleeding in your digestive tract--feeling very weak or dizzy, severe stomach pain, bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds; or signs of bleeding in the brain--sudden numbness or weakness, slurred speech, severe headache, problems with vision or balance.

Avastin can also cause problems with wound healing, which could result in bleeding or infection. Do not use Avastin within 28 days before or after a planned surgery.

Bevacizumab can cause a rare but serious neurologic disorder affecting the brain. Symptoms include headache, confusion, vision problems, feeling very weak or tired, fainting, and seizure (blackout or convulsions). These rare symptoms may occur within hours of your first dose of Avastin, or they may not appear for up to a year after your treatment started. Call your doctor at once if you have any of these side effects.

These uses are considered “off-label” meaning your doctor might use Avastin for unapproved uses if they believe it’s helpful.

Avastin (bevacizumab) is not chemotherapy. It is a monoclonal antibody immunotherapy that binds to a protein called vascular endothelial growth factor (VEGF). Bevacizumab kills cancer by preventing growth of blood vessels that feed tumor growth (an anti-angiogenic). Avastin may be used alone or with chemotherapy to treat certain types of cancer.

In studies of cervical cancer, colon cancer, non-small cell lung cancer and kidney cancer Avastin has been shown to shrink and slow the spread of cancerous tumors when given in addition to other treatments. It also helped some people live longer. Your results with Avastin treatment may differ.

In most cases, you will receive Avastin infusions as long as your cancer is controlled and you are tolerating the side effects. For some diagnoses, you may also receive chemotherapy or only have a certain number of cycles. The length of time you take Avastin depends on your diagnosis and regimen.

In clinical studies, Avastin has been shown to extend the length of time people can live with certain cancers. It can also help extend the time you live without your tumor growing or spreading. It may be given with chemotherapy or other medicines. Your individual success rate may vary from other patients.

Eylea, Eylea HD, and Avastin may all be used to treat neovascular (wet) age-related macular degeneration (AMD), as injections into the eye (intravitreal injections). Both Eylea and Eylea HD are FDA-approved for this indication, but use of Avastin is off-label (not an FDA-approved indication - although it has been used for this purpose since 2005). Eylea HD is a longer acting version of Eylea. Continue reading

A biosimilar is a biological product that is similar to a reference biologic (usually the original product) and for which there are no clinically meaningful differences in terms of safety, purity, and potency.
