Biosimilar filgrastim provides cost savings for treating febrile neutropenia

Professor Aapro and co-authors have performed a cost-efficiency analysis for the three most common granulocyte colony-stimulating factors (G-CSF) products used to treat febrile neutropenia: filgrastim (Neupogen, Amgen) and its biosimilar (Zarzio, Sandoz/Novartis) and the pegylated form of filgrastim, pegfilgrastim (Neulasta, Amgen) [1]. Filgrastim is more cost-efficient than pegfilgrastim for up to 12 days of treatment: beyond 12 days, pegfilgrastim becomes the most cost-efficient of the two. But above all, biosimilar filgrastim is the most cost saving compared to both originator filgrastim and pegfilgrastim.

Sandoz testimony at FDA hearing on biosimilars will emphasise need for consistent regulatory standards across all biologicals
Sandoz announced on 9 May 2012 that Dr Mark McCamish, Head of Global Biopharmaceutical Development, would present on behalf of the Novartis Group of companies (Novartis) at the 11 May 2012 FDA public hearing on draft guidances for biosimilars.

The message he will convey will focus on the need for a single science-based regulatory standard that FDA should apply across all biologicals, irrespective of the business model of the sponsor. As well as a single standard, Dr McCamish will address the points that biosimilar clinical studies should be only confirmatory and the fact that interchangeability is critical to maximising access to affordable biosimilars for US patients.

German pharma giant Bayer told Reuters on 5 May 2012 it had challenged a decision by the Indian Government, which allows India-based generics firm Natco Pharma to sell a generic version of Bayer’s liver and kidney cancer drug Nexavar (sorafenib) in India, before its patent expires in 2020.

Abbott asks FDA to block adalimumab biosimilar

Abbott Laboratories (Abbott) submitted a 30-page citizen petition to FDA on 2 April 2012 asking the agency to reject any biosimilar for its rheumatoid arthritis drug Humira (adalimumab). Abbott says that FDA would be forced to use trade secrets included in Humira’s Biologics License Application (BLA) to approve biosimilars. Abbott is therefore requesting that FDA refuses to review any biosimilar biological whose BLA was submitted before the Biologic Price Competition and Innovation (BPCI) Act of 2009 came into effect on 23 March 2010.
