FDA and biosimilars: process update

Biosimilars/General | Posted 19/08/2011

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?

FDA gives some insight into biosimilar pathway

Biosimilars/News | Posted 12/08/2011

FDA has outlined some of the requirements it intends to include in its biosimilars approval process in an article published in the New England Journal of Medicine [1]. The article is intended to give drugmakers, investors and other interested parties more insight into the approval process for biosimilars.

EMA proposes more precise definition for biosimilars

Biosimilars/Research | Posted 12/08/2011

Members of the Biosimilar Medicinal Products Working Party at the EMA expressed the need to propose a more precise definition for biosimilars due to problems arising from imprecise usage of the term biosimilar in the literature [1].

A biosimilar by any other name …

Following the expiration of patents on the originator molecules, copied products have been introduced into the market. EU regulators have named these products as ‘biosimilars’, that is ‘similar biological medicinal products’; and US regulators refer to them as ‘follow-on biologics’. Specific regulatory pathways have also been established for these biosimilar products, which differ from those for ‘chemical generics’ [1].

Observations on the introduction of biosimilar epoetins into Europe

Biosimilars/Research | Posted 12/08/2011

Professor Wolfgang Jelkmann of the University of Luebeck in Germany has recently published a review article summarising the experiences with biosimilars introduced in the EU after the original biopharmaceutical patents expired [1].

Timing of the launch of biosimilars in Europe

Biosimilars/Research | Posted 12/08/2011

When and where to launch a new biosimilar to ensure that its uptake is the most effective throughout Europe is an issue that affects all pharmaceutical companies working on biosimilars [1].

How cheap will biosimilars need to be

Biosimilars/Research | Posted 05/08/2011

What level of discounts will biosimilars need to provide to be competitive? Some believe that biosimilars will need to provide substantial discounts, being priced as low as 25%, and not 75%, of the originator price [1].

The market for biosimilars

Biosimilars/Research | Posted 29/07/2011

How do the different markets respond to biosimilars? Markets with strong generic adoption frameworks are likely to have good biosimilar adoption as well. However, physician willingness to adopt may be a barrier to entry [1].

Biosimilar regulatory issues

Biosimilars/Research | Posted 08/07/2011

In Europe, the regulatory frameworks for biosimilars are largely established, with both general guidelines and product specific guidelines put in place by the EMA, covering human insulin, somatropin, human growth hormone, erythropoietin, interferon-alpha, low molecular weight heparin and monoclonal antibody. The agency is also currently working on draft guidelines for a number of other product class specific guidelines, including interferon-beta and follicle stimulation hormone.

Biosimilars approved in Europe

Biosimilars/General | Posted 08/07/2011

Last update: 22 April 2025

In the European Union (EU), a legal framework for approving biosimilars was established in 2003. This framework means that biosimilars can only be approved centrally via the European Medicines Agency (EMA) and not nationally.

Development of biosimilars

Costs and risk reduction are facilitating product development of biosimilars [1].

EMA and FDA to collaborate on biosimilars

Biosimilars/News | Posted 01/07/2011

The EMA announced on 23 June 2011 that it had set up a new ‘cluster’ to collaborate with the FDA for the exchange of information on biosimilar drugs.

Current status of biosimilar development

Biosimilars/General | Posted 01/07/2011

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.

Manufacturing of biosimilars

Biosimilars/Research | Posted 24/06/2011

Manufacturing of biosimilars is more challenging than the traditional small molecule generics. Some of the reasons are:

Investments (including operating costs) associated with manufacturing of biosimilars along with the risk of failure for biosimilars are significantly higher than that for small molecule generics. This results in a relatively smaller discount for biosimilars compared to small molecule generics.
Minor changes in manufacturing process can cause significant changes in efficacy or immunogenicity.
Biosimilars are larger and more complex molecules to manufacture.

Partnerships will drive biosimilar development

Biosimilars/News | Posted 24/06/2011

With biosimilars tipped to become a multibillion-dollar market in the coming years, everybody is jumping on the biosimilars bandwagon, and it seems it’s not just limited to pharmaceutical companies.

Does industry support biosimilar user fees in the US?

Biosimilars/News | Posted 24/06/2011

According to FDA, biopharmaceutical trade groups are supportive of its proposal for biosimilar user fees, with sponsors paying an up-front fee with their applications.

Challenges ahead for biosimilar development

Biosimilars/Research | Posted 17/06/2011

Biosimilars, it seems are here to stay, but there is still some way to go before they become commonplace. There is also concern over the associated costs for biological medicines. The cost of biotech therapies is expected to steadily grow by about 30% (an approximately 20 fold increase in 10 years) by 2016.
