Mylan’s Fulphila Pegfilgrastim Biosimilar Launches at Big Discount

The first pegfilgrastim biosimilar Fulphila Pegfilgrastim Biosimilar Launchedlgrastim (Fulphila™) in the US has begun marketing, and Mylan/Biocon are offering a 33% discount to the wholesale acquisition cost (WAC) of the originator product Neulasta®. The Center for Biosimilars reported a communication from Mylan confirming the action. This is a watershed moment for the pegfilgrastim category and could signal the beginning of large savings opportunities for payers and patients.

At a WAC of $4,175 per syringe, the pegfilgrastim biosimilar may be very attractive to health plans and insurers. It is also assumed that this will effectively drive down the average sales price (ASP) of the category over time. The ASP includes the WAC as well as any rebates or discounts given by the manufacturers.

The pegfilgrastim biosimilar, like the reference drug, Amgen’s Neulasta, is approved to decrease the incidence of infection as manifested by febrile neutropenia in patients receiving myelosuppressive chemotherapy.

Although patent litigation between the partners and the maker of the originator product (Amgen), Mylan/Biocon have decided to launch at risk. This means that if the District Court sides with Amgen, Mylan’s could face large financial penalties, including profits on the sales of the biosimilar.
