Imfinzi: Uses, Dosage, Side Effects, and Warnings

What is Imfinzi?

Imfinzi is a brand-name drug. It’s a type of immunotherapy drug, which means it works with your immune system to attack cancer cells. The medication comes as a solution in a single-dose vial. Your healthcare provider will give you Imfinzi intravenously (as an injection into your vein).

Imfinzi is a biologic medication that contains the active drug durvalumab. A biologic is made from parts of living organisms. Imfinzi is not available in a biosimilar form. (Biosimilars [1] are like generic drugs. But unlike generics, which are made for non-biologic drugs, biosimilars are made for biologic drugs.) Instead, durvalumab comes only as of the brand-name drug Imfinzi.
