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.

Deal struck over development of Herceptin biosimilar

Results from a phase I trial of biosimilar infliximab have proven the equivalence of South Korean biotechnology company Celltrion’s biosimilar (CT-P13) and the reference product – Johnson & Johnson’s rheumatoid arthritis blockbuster Remicade (infliximab) in terms of pharmacokinetic parameters, as well as in safety and efficacy in patients with active ankylosing spondylitis [1].

Small molecule versus biological drugs

Biosimilars/Research | Posted 29/06/2012

Biological drugs are large and complex, often consisting of heterogeneous mixtures. They are generally made in genetically engineered cells that impose their own variabilities–in post-translation modifications such as glycosylation–on the processes used to make such drugs.

Amgen welcomes biosimilar monoclonal antibody guideline

Biosimilars/News | Posted 22/06/2012

In a statement issued on 18 June 2012, biologicals major Amgen announced that the company broadly supports the scientific principles behind the guideline on non-clinical and clinical aspects for biosimilar monoclonal antibodies recently issued by EMA [1]. The company added that the guideline aims at maintaining a high standard for approval of a biosimilar in the EU.

Trials of biosimilar monoclonal antibody prove biosimilarity

Biosimilars/News | Posted 22/06/2012

South Korean biotechnology company Celltrion presented the PLANET clinical studies results of phase I and phase III trials for its first monoclonal antibody biosimilar (CT-P13) of Johnson & Johnson’s rheumatoid arthritis blockbuster Remicade (infliximab) at the Annual Congress of the European League Against Rheumatism (EULAR) held in Berlin, Germany, on 6–9 June 2012. The results demonstrated the biosimilarity of CT-P13 to the reference drug, supporting the company’s intention to launch the biosimilar monoclonal antibody globally.
