What is the difference between Udenyca and Neulasta?

Udenyca (pegfilgrastim-cbqv) is a biosimilar to Neulasta (pegfilgrastim).

A biosimilar is a biological product that is very similar to a reference biologic (such as Neulasta) and for which there are no clinically meaningful differences in terms of safety, purity, and potency.

Neulasta and Udenyca are classified as colony-stimulating factors. Colony stimulating factors are used in patients who are undergoing cancer treatments that cause low white blood cell counts (neutropenia) and puts the patient at risk of infection. These medications boost production of white blood cells in response to infection and help to reduce the time when a patient is neutropenic.
