Pronunciation: Av-ZEE-vee
Generic name: bevacizumab-tnjn
Dosage form: injectable injection
Drug class: VEGF/VEGFR inhibitors

Medically reviewed by Carmen Pope, BPharm. Last updated on Dec 11, 2023.

Avzivi (bevacizumab-tnjn) is a vascular endothelial growth factor (VEGF) inhibitor biosimilar to Avastin that may be used to treat colorectal cancer, non-small cell lung cancer, glioblastoma, renal cell carcinoma, cervical cancer, and epithelial ovarian, fallopian tube, or primary peritoneal cancer.

Some cancers are good at building new blood vessels, which helps them grow quickly. They activate this process by sending signals to nearby tissues and activating certain growth factors, such as VEGF, which allow the tumor to form new blood vessels.

Avzivi (bevacizumab-tnjn) works by locating and binding to VEGF molecules, preventing their interaction with VEGF receptors (Flt-1 and KDR) on the surface of endothelial cells. This prevents the proliferation of endothelial cells and reduces new blood vessel formation, reducing cancer growth and cancer progression.

Avzivi is a biosmilar to Avastin. A biosimilar means that the biological product is approved based on data demonstrating that it is highly similar to Avastin, known as the reference product, and that there are no clinically meaningful differences between the biosimilar product and the reference product concerning indication(s), dosing regimen(s), strength(s), dosage form(s), and route(s) of administration.

Avzivi was FDA approved on December 6, 2023.

Warnings

Not indicated for the adjuvant treatment of colon cancer.

Avzivi 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 including your gastrointestinal tract or any organ in your body. Call your doctor if you have signs of bleeding in your digestive tract, such as 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 including sudden numbness or weakness, slurred speech, severe headache, or problems with vision or balance.

Avzivi can also cause problems with wound healing, which could result in bleeding or infection. Do not use within 28 days of 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 seizures (blackouts or convulsions). These rare symptoms may occur within hours of your first dose of Avzivi, or they may not appear for up to a year after your treatment starts. Call your doctor at once if you have any of these side effects.

Avzivi may also increase your blood pressure, cause damage to your kidneys, or cause Posterior Reversible Encephalopathy Syndrome (PRES) – an acute neurological disorder that may cause seizures or headaches. Your healthcare provider will monitor you for these.

Some people receiving Avzivi have reacted to the infusion (when the medicine is injected into the vein). Tell your medical caregiver right away if you feel dizzy, nauseated, light-headed, sweaty, itchy, or have a fast heartbeat, chills, wheezing, or chest pain during the injection.

May cause fetal harm and you will need to use adequate contraception if you are a woman of childbearing potential.

There is also a potential risk for ovarian failure and congestive heart disease.

Before taking

You may not be able to use Avzivi if you are being treated with other cancer medicines such as doxorubicin, or daunorubicin, or if you have or ever had:

• slow healing of a skin wound or surgical incision
• surgery within the past 4 weeks (28 days) or you plan to have surgery within the next 4 weeks (28 days) or
• coughing up blood or vomit that looks like coffee grounds.
