The cost-effectiveness of biosimilars

Biosimilars/Research | Posted 16/12/2011

The biotechnology market is growing rapidly, driven by the imminent patent expiry of several major biologicals and enabled by the establishment of regulatory frameworks. The key driver for the biosimilars market is likely to be cost containment pressures in healthcare systems in the context of aging populations and of the current financial and economic crisis [1]. Because the medicines involved are so expensive, even a modest price reduction in percentage terms generates savings in the billions of euros over the EU as a whole [2].

Health Canada definitions of generics and biosimilars

Biosimilars/General | Posted 16/12/2011

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.

Interchangeability (switching and alternating) of biosimilars

Biosimilars/Research | Posted 09/12/2011

The Biologics Price Competition and Innovation (BPCI) Act of 2009 established an abbreviated Biologic License Application (aBLA) pathway for the approval of biosimilars in the US. This act also established the principles of interchangeability (along with switching and alternating) with the reference product. However, the concept of biosimilarity and interchangeability for biosimilars is very different from that of bioequivalence and drug interchangeability for generics [1].

Indian Transgene sells biosimilar to German TSS Export

Quantitative evaluation of bioequivalence

Biosimilars/Research | Posted 02/12/2011

Generics
For approval of small molecule generics, FDA requires that evidence of average bioequivalence in drug absorption in terms of pharmacokinetic (PK) parameters be provided through the conduct of bioequivalence studies. This may be done using the area under the blood and/or plasma concentration-time curve and peak concentration (Cmax) [1].

US cancer researcher calls for additional biosimilar trials

Biosimilars/Research | Posted 02/12/2011

One of the leading cancer researchers in the US has called for biosimilars manufacturers to undertake additional research. In an interview with The ASCO Post, Professor Mark Pegram, MD, Professor of Medicine and Associate Director for Clinical Research, Sylvester Comprehensive Cancer Center at the University of Miami Health System, Florida, USA, said, ‘Oncologists will be concerned about the safety of biosimilars. They will want to ensure that the chemistry, manufacturing, and composition are on par with the labelled product.’

Speed to market critical in biosimilar development

Biosimilars/General | Posted 18/11/2011

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.

Confusion surrounding terms used in the global field of generics and biosimilars is a recognised problem.

US biosimilars: many barriers to overcome

Biosimilars/Research | Posted 18/11/2011

EMA has been successful in devising a system for authorising the marketing of biosimilar products and 14 biosimilars are currently on the market in the major countries of the EU [1]. Generally, biosimilars are priced about 30% less than the originator product. This seems to be sufficient to gain significant (~ 30%) market share in a year or two though it keeps biosimilars very expensive. This is in dramatic contrast to the situation in America. In 2010 the ‘biosimilars statute’ (BLA) eventually came into force as the result of the Patient Protection and Affordable Care Act. The proposed rule involves two particularly onerous requirements that the EU process avoids.

The first is the question of degree of similarity.
