Biosimilars will not be able to use ANDA pathway to approval

Biosimilars/General | Posted 30/03/2012

FDA’s highly anticipated guidance for biosimilars finally arrived on 10 February 2012 with the release of three draft guidance documents [1]. Some have complained that the guidance is too vague, however, FDA’s denial of three citizen’s petitions have perhaps made some issues clearer.

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.

European biosimilars market to reach almost US$4 billion by 2017

Biosimilars/News | Posted 09/03/2012

According to researchers at Frost & Sullivan, the European market for biosimilars will experience strong growth in the coming years due to patent expiries of blockbuster biologicals between 2010 and 2017. Cost containment strategies being implemented by governments and healthcare service providers are also given credit for shifting sales towards cheaper biosimilars.

Comparability studies and substitution of biosimilars

Biosimilars/Research | Posted 09/03/2012

In order to demonstrate similarity between the biosimilar and the biological reference product, both products must be compared to satisfy quality, safety and efficacy requirements [1].

Biosimilar alliance between Celerion and Ricerca

Biosimilars interchangeability, increased costs and burden for FDA

Biosimilars/General | Posted 02/03/2012

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.

Oncologists urged to embrace biosimilars to help control spiraling costs of cancer care

Biosimilars/Research | Posted 24/02/2012

Oncologists have been urged to embrace biosimilar drug substitution to help control the spiraling costs of cancer care. However, they have been warned that the optimal realisation of such a programme requires successful educational initiatives and the development of effective working partnerships with pharmacists and patients [1].

Regulation of biosimilars in the US

Biosimilars/News | Posted 24/02/2012

The US pharmaceutical industry plays a vital role in shaping the face of American health care. With major patent expiries and thin product pipelines, the industry is now considering new directions to maintain growth and stability. Biological drugs, derived from living organisms, represent a growing opportunity for big pharmaceutical firms. They command high prices, will probably have fewer firms making them than generics due to high barriers to entry, and play to the existing strengths of big pharma firms. But will the recent healthcare legislation provide the way for consistent FDA regulation? What is the most likely way in which biologicals will enter the market over the next few years?

Biosimilars: demonstrating ‘similarity’

Biosimilars/Research | Posted 17/02/2012

Most biological drugs are mixtures of closely related compounds, some of which are probably more active than others. Today, the state-of-the-art manufacturing struggles to deliver material that is similar to the prior batch from the same facility and team [1]. Identical is currently not possible, therefore ‘similar’ is the route that authorities in Europe and the US are going down.

Quality by design in biomanufacturing

Biosimilars/General | Posted 17/02/2012

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?

Biosimilars/Research | Posted 10/02/2012

Registration of biosimilars in Europe and the US

Biosimilars/Research | Posted 10/02/2012
