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.

Biosimilars/Research | Posted 10/06/2011

Regulatory approvals for new biological drugs in the US have nearly doubled in the last decade compared with the 1990s, according to the May/June 2011 issue of the Tufts Center for the Study of Drug Development (CSDD) Impact Report. However, the author of the report, Research Assistant Professor Janice Reichert, said there are still ‘substantial challenges’ to be faced by biologicals manufacturers if they wish to ‘maintain that pace’.

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).

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.

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.
