Frequently asked questions about UDENYCA and biosimilars

What is UDENYCA?

UDENYCA is a prescription medicine used to help reduce the chance of infection due to a low white blood cell count, in people with certain types of cancer (non-myeloid), who receive anti-cancer medicines (chemotherapy) that can cause fever and low blood cell count.

What are biosimilars?

Biosimilars are FDA-approved biologic medications that are as safe and effective as the original biologics (known as the reference product). Biosimilars have no clinically meaningful differences from the reference product. This means that there is no compromise in safety and effectiveness of the biosimilar when compared to the reference product. Biosimilars introduce competition into the marketplace and can lower the cost of treatment.

Why does chemotherapy cause low white blood cell counts?

Chemotherapy works by targeting cancerous cells. It can also affect and lower healthy cell counts, including the white blood cells that fight infections.

Who should not take UDENYCA?

Do not take UDENYCA if you have had a serious allergic reaction to human G-CSFs, such as pegfilgrastim or filgrastim products.

Before you receive UDENYCA, tell your healthcare provider about all of your medical conditions, including if you have a sickle cell disorder, have kidney problems, are pregnant or plan to become pregnant (it is not known if UDENYCA will harm your unborn baby), are breastfeeding or plan to breastfeed (it is not known if UDENYCA passes into your breast milk).
