A biologic is a medicine that is made in a living system, such as yeast, bacteria, or animal cells. A biosimilar is a medicine that is very close in structure and function to a specific biologic medicine (also known as the reference product). The biosimilar has a structure that is highly similar to, but not exactly the same as, the brand name biologic. A biosimilar behaves in much the same way, so that there are "no meaningful differences" between it and the original biologic. To learn more, see What Are Biosimilar Drugs?
For some brand name biologics used in the treatment of cancer, one or more biosimilars are now approved for use by the US Food and Drug Administration (FDA).
