Is pegfilgrastim superior to filgrastim for the treatment of febrile neutropenia?

Biosimilars/Research | Posted 17/08/2012

A study to compare the cost-efficiency of three different recombinant granulocyte colony-stimulating factors (G-CSFs) for the treatment of chemotherapy-induced febrile neutropenia assumes that they are of comparable efficacy. But how solid is the evidence for this assumption? A study by Professor Matti Aapro and co-authors explores the available evidence regarding efficacy for the three G-CSFs, filgrastim (Neupogen, Amgen), pegfilgrastim (Neulasta, Amgen) and a filgrastim biosimilar (Zarzio, Sandoz/Novartis) and concludes that evidence behind previous claims of superiority for pegfilgrastim is ‘similar’ and ‘open to question’ [1]. Thus, originator and biosimilar filgrastim appear to be holding ground in the efficacy stakes.

FDA urged to exclude plasma protein therapies from biosimilar pathway

Biosimilars/General | Posted 03/08/2012

FDA is being lobbied by patient and industry groups to exclude plasma protein therapies from its pathway for the approval of biosimilars. FDA has a mandate to create a new abbreviated process for the approval of biosimilars under the Biologics Price Competition and Innovation Act of 2009, which was part of the new healthcare reform law passed in March 2010 [1]. This potentially brings cheaper products to market sooner, and so increases the availability of affordable health care. However, it also means that manufacturers applying for approval for new biosimilars may be able to skip clinical testing if they can demonstrate sufficient similarity with reference products.
