Biosimilars

Prescriber caution is likely over biosimilars

The experience with generic medicines is a sign that prescribers are likely to be cautious, and in some cases concerned, about the use of biosimilars as alternatives to brand-name drugs.

The move could mean that the Supreme Court rejects the whole healthcare law, including the biosimilars pathway created by the healthcare reform.

Biosimilars approved and marketed in Belgium

Last updated: 18 May 2012

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.

Bayer opposes sorafenib compulsory licence in India

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.

Current and future issues surrounding biosimilars

Biological medicines are already becoming an increasingly important part of health care. With patent expiries on originator biological products, biosimilars are also increasingly become a part of this future [1]. In fact, by 2020 twelve of the top-selling biologicals will have lost patent protection, opening up an estimated US$24 billion in EU sales and US$30 billion in US sales [2].

Amgen and AstraZeneca make monoclonal antibody deal
Biotech giant Amgen and pharma major AstraZeneca announced on 2 April 2012 an agreement to jointly develop and commercialise five monoclonal antibodies from Amgen’s clinical inflammation portfolio (AMG 139, AMG 157, AMG 181, AMG 557 and brodalumab [AMG 827]), which are expected to be used to treat inflammatory diseases.

As part of the deal AstraZeneca will make an upfront payment of US$50 million and the companies will then share both costs and profits. The collaboration will provide Amgen with additional resources to optimally progress its portfolio and Amgen will benefit from the strong respiratory, inflammation and asthma development expertise of MedImmune–AstraZeneca’s biologicals arm.

Reimbursement of biosimilars

The evidence required to obtain marketing authorisation for a biosimilar by the regulatory authority is not always the same as that required by the reimbursement authority [1]. This can cause problems for biosimilars manufacturers when planning clinical trials in order to obtain both marketing and reimbursement approval.
