American dermatologists update position statement on biosimilar substitution

On 3 November 2012, the American Academy of Dermatology (AAD) updated its position statement on generics and biosimilar substitution to reflect its views, in particular on interchangeability* and naming of biosimilars.

EMA definitions of generics and biosimilars

Confusion surrounding terms used in the global field of generics and biosimilars is a recognised problem. The members of the Biosimilar Medicinal Products Working Party at EMA have recently expressed the need to propose a more precise definition for biosimilars due to problems arising from imprecise usage of the term in the scientific literature and elsewhere [1].

Biosimilars applications under review by EMA

Last update:  11 January 2013 

EMA is the body responsible for approval of biosimilars within the EU. A legal framework for approving biosimilars was established in 2003.  Approval of biosimilars is based on an abbreviated registration process, which allows biosimilars manufacturers to provide a reduced package of information compared to originator drugs, provided they can prove ‘similarity’ to the originator or ‘reference drug’.

Teva asks FDA to delay approval of Biogen’s MS drug

Teva Pharmaceutical Industries (Teva) has petitioned FDA not to approve Biogen Idec’s (Biogen’s) investigational pill for treatment of multiple sclerosis, BG-12 (dimethyl fumarate), citing safety concerns.

EMA publishes revised biosimilar Q&A document for patients

On 27 September 2012 EMA published its revised Questions and Answers (Q&A) document on biosimilar medicines aimed at patients and the general public.

Naming and interchangeability of biosimilars raised in new survey

The contentious issues of naming and interchangeability of biosimilars in the US have been raised once again, as a result of a survey carried out by the Alliance for Safe Biologic Medicines (ASBM). The survey, released on 13 September 2012, examined physician practices and perspectives with regard to identification and substitution of biosimilars. These remain issues that are as yet unresolved by FDA.

Bioequivalence of biosimilar trastuzumab to Herceptin proven in phase I trial
Biopharmaceutical company Synthon announced on 22 March 2012 that all in vitro and in vivo studies conducted so far have shown the biosimilar behaviour of Synthon’s trastuzumab in comparison with the reference product, Herceptin. The outcome of the phase I clinical trial confirmed these results, showing bioequivalence of Synthon’s trastuzumab to Herceptin. Synthon confirmed that its biosimilar trastuzumab will now enter a confirmatory phase III clinical trial in breast cancer patients.

FDA urged to exclude plasma protein therapies from biosimilar pathway

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.

US supreme court ruling means biosimilars pathway safe

On 28 June 2012 the US Supreme Court ruled in favour of the bulk of the Affordable Care Act, meaning that the biosimilars pathway, which is part of the act, is now also safe.

US Supreme Court looks set to challenge Affordable Care Act

The United States Supreme Court is reviewing the constitutionality of the provision in the Affordable Care Act providing that individuals should take personal responsibility for paying for their health care by obtaining health insurance or pay a fine. 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 

The Federal Agency for Medicines and Health Products (FAMHP), formerly the Directorate-General for Medicinal Products of the Federal Public Service (FPS) Public Health, created in January 2007, is the official authority for medicines and health products in Belgium and is also responsible for authorising biosimilars in Belgium [1]. This is carried out via the EU procedures (centralised, national, mutual recognition or decentralised) and following EMA guidelines for biosimilars.

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.

Biosimilars interchangeability, increased costs and burden for FDA

Biosimilars manufacturers in the US are faced with many hurdles, including untested regulatory pathways, patent challenges and manufacturing issues associated with making such complicated molecules. On top of this drugmakers also need to take into account the higher marketing costs that may be associated with biosimilars.

Quality by design in biomanufacturing

In January 2011, FDA published its long-awaited guidance for industry on Process Validation: General Principles and Practices [1].This replaces the previous 1987 version (updated 2004) and it is understandably a big change for some whose whole career has been dominated by the previous approach. The question is: why was a change needed and how drastic is it?

Health Canada definitions of generics and biosimilars

Attention has been brought to the fact that there is confusion surrounding terms used in the global field of generics and biosimilars. Some of this confusion has been attributed to authorities in various regions of the world defining terms differently and other instances are due to a misunderstanding of the actual nature, characteristics, and method of research and manufacture of these biological products.

Speed to market critical in biosimilar development

For companies looking to develop biosimilars speed to market is critical, but this must not be done by sacrificing product quality, according to a report from Contract Research Organisation (CRO) Quintiles. The most successful biosimilar companies will be those who collapse their clinical, commercial, and regulatory thinking into a streamlined cohesive function in order to expedite commercialisation and optimise market access.

FDA and biosimilars: update on key themes

Since the existence of a legal pathway for biosimilars was made possible by the signing of the 2009 Biologics Price Competition and Innovation (BPCI) Act in 2010 by President Barack Obama, FDA has declared itself ‘open for business’ for biosimilars [1]. But what is the thinking of FDA and what should we expect from any guidance on biosimilars?

FDA and biosimilars: process update

Despite the fact that a legal pathway for the approval of biosimilars in the US has existed for more than a year, formal guidance has still not been issued by FDA. This has led many to question when, or even if, biosimilars will come onto the market in the US [1]. So what has FDA been doing in the meantime and how close are we to seeing some biosimilar guidance in the US?

Current status of biosimilar development

Widespread therapeutic use of biological pharmaceutical products appears to be inevitable. Nevertheless, the law governing approval of biosimilar products in the US is still not in place. The size of the biologicals market and impending patent expiries, however, are making approval of a practical pathway for biosimilars more urgent.

Market opportunities for biosimilars

Although growth in annual spending on medicines is set to reduce, there is still a huge market out there and spending on biosimilars is expected to increase in the coming years.

Enoxaparin biosimilar or not

A biosimilar of the low molecular weight heparin, enoxaparin, produced by Sandoz (Novartis’s generics division) was approved by the FDA on 23 July 2010. However, some question whether this was really a biosimilar or not.

Biobetters rather than biosimilars

‘Biobetters’, rather than biosimilars, are the next big opportunity for biopharm and contract research organisations (CROs) hoping to profit from patent expirations on biologicals, say experts.

The history of the US biosimilar regulatory pathway

The US, although it now has a legal pathway (with the approval of the Biologics Price Competition and Innovation Act [BPCI Act], which was signed into law on 23 March 2010 by President Barack Obama), does not yet have a practical pathway with guidance defined by the FDA.

More debate over the exclusivity period for biological in the US

The debate over the length of exclusivity that biological drugs can enjoy before competition from biosimilars ensues seems set to be a long and complicated one. The latest group to join in the debate is the Office of the US Trade Representative (USTR).

Questions over US biosimilars pathway in light of Teva’s BLA

Questions have arisen over whether the abbreviated pathway for approval of biosimilars in the US will ever be used. Many believe that biosimilars manufacturers will opt out of this pathway and use the normal route via a Biologic License Application (BLA). This is backed up by the fact that Teva’s biosimilar, Neutroval, was submitted to the FDA via the normal BLA route.
