Standards for biosimilars or ‘alternative’ biologicals in India

Biosimilars/Research | Posted 10/06/2011

In the highly regulated market of the EU clear and rigorous guidelines exist for approval of biosimilars. In the EU biosimilars must ensure the same quality, safety and efficacy, as any other product, along with demonstrating biosimilarity (comparability) with the reference product.

More debate over the exclusivity period for biological in the US

Biosimilars/General | Posted 10/06/2011

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).

Lupin and Neuclone biosimilars agreement

Indian generics manufacturer Lupin Pharmaceuticals has signed an agreement with Australian biotech firm NeuClone to access cell line technology to be used to develop biosimilar drugs targeting cancer.

Need for a global pathway for biosimilars

Biosimilars/Research | Posted 06/06/2011

The need for access to biosimilars is global, yet the regulations are national. Issues with this approach are discussed by Dr Mark McCamish and Dr Gillian Woollett in their published paper [1].

Enoxaparin biosimilar or not

Biosimilars/General | Posted 06/06/2011

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.

Interchangeability or substitution of biosimilars

Biosimilars/Research | Posted 27/05/2011

The interchangeability or substitution of biosimilars is a subject that differs somewhat between Europe and the US. These different approaches to biosimilars are discussed by Dr Mark McCamish and Dr Gillian Woollett in their published paper [1].

Interchangeability of biosimilars in the US

Biosimilars/News | Posted 27/05/2011

As drug manufacturers await guidance on a biosimilar approval pathway in the US, the debate goes on as to how high the bar will be set for the FDA to designate a biosimilar as interchangeable. In one critical area of the law that outlines biosimilar regulations, Congress outlines the difference between biosimilarity and interchangeability with respect to biosimilars and innovative biologicals, but the FDA has yet to define the difference.

Etanercept and quality attributes changes

Biosimilars/Research | Posted 27/05/2011

Quality changes in commercially available etanercept (Enbrel) were found by Sandoz researchers over a period of time. Since the drug remained on the market with an unchanged label, this would indicate that the changes were accepted by the health authorities [1].

Regulatory approach to biosimilar development

Biosimilars/Research | Posted 20/05/2011

Legislation in Europe in 2004 created a legal pathway for approval of biosimilars and the first biosimilar, Omnitrope (somatropin) as approved by the EMA in 2006. The US is lagging behind somewhat, having only just approved a legal pathway in March 2010 and with practical guidance from the FDA still anticipated.

Quality attribute changes for rituximab

Last updated: 4 April 2013

Sandoz researchers found quality changes in commercially available rituximab (Rituxan/Mabthera) over a period of time. Since the drug remained on the market with an unchanged label, this would indicate that the changes were accepted by the health authorities.

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

Biosimilars/General | Posted 20/05/2011

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.

TNF copy biological approved in China

Biosimilars/News | Posted 20/05/2011

China-based Simcere Pharmaceutical Group (Simcere) announced on 9 May 2011 that Shanghai Celgen Bio-Pharmaceutical (Shanghai Celgen) has received approval for Qiangke – a copy biological version of etanercept – by the Chinese authorities.

Comparability for biosimilar development

Biosimilars/Research | Posted 13/05/2011

How does ‘comparability’ apply to biosimilar drug development? This was the question discussed by Dr Mark McCamish and Dr Gillian Woollett [1].

Biosimilars user fees as high as brand-name fees

Biosimilars/News | Posted 13/05/2011

On 9 May 2011, the FDA proposed a user fee programme that would see drugmakers seeking approval to market biosimilars in the US initially paying fees similar to those required of originator biological drug developers.

Changes in the quality attributes of darbepoetin alfa

Biosimilars/Research | Posted 13/05/2011

Quality changes over a period of time were found in commercially available darbepoetin alfa (Aranesp) by Sandoz researchers. Since the drug remained on the market with an unchanged label, this would indicate that the changes were accepted by the health authorities [1].

Brazil to manufacture follow-on adalimumab

Biosimilars/News | Posted 13/05/2011

The Brazilian Ministry of Health (Ministério da Saúde) announced on 5 April 2011 that it would be entering into an agreement with PharmaPraxis to manufacture a biosimilar, or follow-on version, of Abbott’s monoclonal antibody Humira (adalimumab).

Acceptable changes in quality for glycosylated biologicals

Biosimilars/Research | Posted 06/05/2011

Research carried out by Sandoz into three glycosylated protein biotechnology drugs currently on the market showed quality changes over the period studied. Since all three drugs remained on the market with unchanged labels, this would indicate that the changes were accepted by the health authorities [1].

Opportunities for biosimilar development

Biosimilars/Research | Posted 06/05/2011

Rising drug costs and limited healthcare budgets across the world, coupled with the fact that many biotechnology drugs will soon lose their patent protection, means that there is a huge opportunity for biosimilar manufacturers.

Biobetters rather than biosimilars

Biosimilars/General | Posted 06/05/2011

‘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.
