Non-biological complex drug concept: experiences with iron sucrose and low molecular weight heparin

Biosimilars/Research | Posted 12/12/2014

When the patent of a classical small molecule drug expires, generics may be marketed if their therapeutic equivalence to the originator drug has been established. The therapeutic equivalence of a drug includes both pharmaceutical equivalence and bioequivalence and do not require formal clinical efficacy and safety studies. The demonstration of therapeutic equivalence then allows for the interchangeability of the generic and originator drug. This approach has so far only been applied to products that can be fully characterized. For more complex molecules, which are difficult to characterize, such as proteins, the demonstration of bioequivalence requires an alternative approach.

Challenges for the regulation of biosimilars

Biosimilars/Research | Posted 25/04/2014

The European Medicines Agency (EMA) was the first agency to issue guidelines for the approval of biosimilars via an abbreviated registration process back in 2006. Since then the agency has developed many general and specific guidelines for biosimilars, as well as approved 18 biosimilars to date [1]. Tsiftsoglou and co-authors, however, believe that many challenges still lie ahead for this class of biologicals, some of which are discussed here [2].

Quality by design for biosimilars

Biosimilars/Research | Posted 11/04/2014

A study into the use of quality by design (QbD) has demonstrated how risk management can facilitate the implementation of QbD in the early-stage product development of biosimilars [1].

Cost savings to be made by switching to Zarzio

Biosimilars/Research | Posted 04/04/2014

Since the first filgrastim biosimilar was approved in 2008, there is now five years of data on which to assess the efficacy, safety and cost-effectiveness of biosimilar granulocyte colony-stimulating factors (G-CSFs). A pooled analysis of post-approval studies of one of the most common biosimilar G-CSFs, Zarzio (filgrastim), is presented by Pere Gascón and co-authors [1]. Their findings highlight significant cost savings in health authority regions that have switched from the originator G-CSF to its biosimilar Zarzio. The study overturns early concerns that cost savings would not be so great as hoped [2].

Regulatory principles for biosimilar monoclonal antibodies

Biosimilars/Research | Posted 18/04/2014

It is sometimes argued that there is less clinical evidence for biosimilars. However, Tsiftsoglou and co-authors pointed out that European Medicines Agency (EMA) guidelines for biosimilars are not primarily driven by feasibility considerations or to make it as easy as possible, but to add to the totality of evidence. And it is this that finally drives the regulatory acceptance of a biosimilar [1].

Are biosimilars worth it?

Biosimilars/Research | Posted 21/03/2014

Will off-patent biological medicines offer the same cost savings as those seen with off-patent non-biological (chemically derived) medicines? A group of health economists based in Brussels, Belgium, have begun to address the question in light of increasing numbers of biological medicines going off patent and the new phenomenon of biosimilar competition [1].

Since the expiration of patent protection, a number of biosimilars have also been approved on the world market.

Inflammatory arthritis: auditioning for the role of biosimilar

Biosimilars/Research | Posted 28/02/2014

Targeted biological therapies have proven themselves highly effective in the treatment of inflammatory joint diseases, but their benefits are restricted by cost. Biosimilars of these therapies would offer affordable alternatives, but establishing biosimilarity presents many challenges, write Professors Jonathan Kay and Josef Smolen [1].

Guiding principles for biosimilars development

Biosimilars/Research | Posted 21/02/2014

In contrast to chemically synthesized small-molecule drugs, biologicals have complex structures of high molecular weight. Therefore, even small changes in the production processes may lead to differences in the final product. The manufacturers of the originator product are not required to disclose their manufacturing process after the patent expiry. This gap in knowledge increases the probability of introducing changes in the manufacturing process of biosimilars, making producing an identical copy of a biological virtually impossible. Indeed, even different batches of the same originator biological may show a certain level of heterogeneity.

Use of formularies could increase use of biosimilars

Biosimilars/Research | Posted 14/02/2014

Whether or not the US Food and Drug Administration (FDA) permits automatic substitution of biosimilars, healthcare systems can still consider using formularies as a way to increase the use of more affordable biosimilars [1].

The case for improving biosimilar regulatory frameworks worldwide

Biosimilars/Research | Posted 07/02/2014

In developing countries, where the cost benefits of biosimilar drugs would have the greatest impact, the financial investment needed to develop biosimilars renders them inaccessible. The situation requires increased input from international evaluation frameworks, such as those of the World Health Organization (WHO); write Barbara Milani and Sara Gaspani of Médecins Sans Frontières, Geneva, Switzerland [1].

Improving access to HCV treatment in developing countries

Biosimilars/Research | Posted 31/01/2014

Hepatitis C virus (HCV) infection affects 150–180 million people worldwide each year, killing an estimated 350,000. The considerable cost of treatment – US$ 10,000–US$20,000 per patient for a 48-week course – presents an insurmountable barrier in developing countries, where the disease burden is greatest. Barbara Milani and Sara Gaspani of Médecins Sans Frontières, Geneva, Switzerland, have collected information on biosimilars and other alternatives to the current recommended treatment, pegylated interferon alpha (in combination with ribavirin) [1]. With these findings, they hope to accelerate the search for feasible, accessible alternatives to current therapies.
