Imfinzi

Generic Name: durvalumab (dur VAL ue mab)
Brand Names: Imfinzi

What is Imfinzi?

Imfinzi (durvalumab) is a cancer medicine that works with your immune system to interfere with the growth and spread of cancer cells in the body.

Imfinzi is used to treat cancer of the bladder or urinary tract.

Imfinzi is usually given when the cancer cannot be removed with surgery and has not responded to chemotherapy with other medicines.

Imfinzi was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, tumors responded to this medicine. However, further studies are needed.

Important information

Imfinzi works by causing your immune system to attack tumor cells. Durvalumab may cause your immune system to attack healthy organs and tissues in your body. This could lead to serious or life-threatening side effects on your lungs, liver, pancreas, kidneys, intestines, thyroid, or adrenal glands.

Call your doctor at once if you have symptoms such as: fever, flu symptoms, muscle pain or weakness, vision changes, chest pain, trouble breathing, severe stomach pain or diarrhea, skin rash, increased or decreased urination, weight changes, hair loss, dark urine, or jaundice (yellowing of your skin or eyes).
