Is Fulphila a chemo drug?

Official answer


No, Fulphila is a prescription medicine used to boost the number of white blood cells in cancer patients receiving chemo. Fulphila is a man-made form of a protein known as a colony stimulating factor used to help prevent neutropenia (low white blood cells) and possible infections due to chemotherapy.

Lower levels of white blood cells can increase your risk for infection and fever, especially during chemotherapy. Colony stimulating factors stimulate the bone marrow to make more neutrophils, a type of white blood cell, which move into your bloodstream and fight infection.

Colony stimulating factors can help you stay on track with your cancer treatments, but not everyone needs medicine to increase their white blood cells during chemotherapy. Your doctor will determine your need for this treatment.

Fulphila (pegfilgrastim-jmbd) is a biosimilar to Neulasta (pegfilgrastim). Neulasta was the first pegfilgrastim agent approved in 2002. Fulphila, approved in June 2018, was the first biosimilar to Neulasta. It is made by Mylan Pharmaceuticals.

Biosimilars to Neulasta include:

A biosimilar is a biological product that is highly similar to a U.S.-licensed reference biological. Biosimilars can provide cost-effective treatment options to already approved biologics.
