Comparison of the markets for biosimilars and generics

Biosimilars/Research | Posted 03/04/2015

Biosimilars/Research | Posted 27/03/2015

Healthcare spending on prescription medications comprises 1.6% of gross domestic product (GDP) in the US and continues to rise. Brand-name prescription medications – both small-molecule and biological drugs – are the primary driver of this growth, increasing 15% in price in 2014 alone [1].

Survey among pharmacists shows high confidence for biosimilar substitution when same generic name is used

Biosimilars/Research | Posted 20/03/2015

Approximately 75% of pharmacists indicated that they would be confident or very confident in substituting an interchangeable biosimilar with the reference product if both shared the same active ingredient or non-proprietary name of the reference biological, according to a survey published in JMCP [1].

Equivalent safety and efficacy of nephrology subsequent entry biologics in Canada

Biosimilars/Research | Posted 13/03/2015

A review of efficacy and safety data for subsequent entry biologics (SEBs) used in nephrology practice in Canada has found little clinical difference between epoetin SEBs and the reference product. But while the clinical differences are minimal, argue the authors, the financial implications of a possible dose difference between epoetin zeta and the reference product should be considered in future pharmacoeconomic studies [1].

Comparison of non-originator filgrastim with Neupogen finds no difference in neutropenia recovery periods

Biosimilars/Research | Posted 06/03/2015

Results of an observational study found no difference in Biocad’s non-originator filgrastim (Leucostim) compared to Neupogen in the recovery periods for patients with chemotherapy-induced neutropenia [1].

Generics and off-patent biologicals for cancer treatment in developing countries

Biosimilars/Research | Posted 20/02/2015

The understandable focus on infectious diseases, such as human immunodeficiency virus (HIV), malaria and tuberculosis (TB), has meant that an increasing burden of non-communicable diseases (NCDs), notably cancer, now needs urgent attention across developing countries [1]. Generics and biosimilars offer a lower-cost approach to treatment, but these drugs raise challenges of their own.

Biosimilars compared to generics in the European market

Biosimilars/Research | Posted 13/02/2015

Once a patent expires, price competition is possible since any manufacturer can copy the originator product. This circumstance justifies the place in the pharmaceutical market for generics and biosimilars, i.e. off-patent medicines to be sold at lower prices than their originators [1].

Impact of nephrology subsequent entry biologics in Canada

Biosimilars/Research | Posted 06/02/2015

Subsequent entry biologics (SEBs) may soon be a reality in Canadian nephrology practice. Along with opportunities to reduce healthcare costs, these agents pose unique challenges to successful implementation. Understanding the experiences around the globe in both regulatory affairs and implementation will be a valuable guide for Canadian clinicians. This review should assist clinicians and policymakers to navigate this complex subject and to make informed decisions in the best interest of their patients [1].

Improved labelling sought for biosimilar acceptance

Biosimilars/Research | Posted 31/10/2014

The terms of approval for every biosimilar and its reference product must be made clearer, argue the European Biopharmaceutical Enterprises (EBE) [1]. The development of biosimilar regulatory pathways worldwide has been led by the European Medicines Agency (EMA) [2], but EMA’s information-driven stepwise approach is only reflected in a single section of the product labelling for healthcare professionals and patients, which so far has followed a generic approach in Europe.

Members of the European Medicines Agency's (EMA) Biosimilar Medicinal Products Working Party (BMWP) address these concerns using extrapolation of indications in biosimilar epoetin as an example [1].

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.

US biosimilar uptake in the light of Obamacare

Biosimilars/Research | Posted 05/12/2014

A literature review by researchers at Tufts University in the US concludes that market uptake of biosimilars in the US will depend on regulatory policies, including the smoothing out of issues concerning the country’s Food and Drug Administration (FDA) regulatory pathway [1, 2]. The review comes in the light of a new approval pathway for biosimilars established as part of the US Government’s Affordable Care Act, more widely known as Obamacare.

Comparison of biosimilar filgrastim versus other G-CSF formulations after autologous stem cell transplantation

Biosimilars/Research | Posted 28/11/2014

Introduction
Only limited data have been so far published about the use of biosimilar filgrastim in haematologic recovery after autologous stem cell transplantation (ASCT). Despite the limitation due to retrospective analysis performed on a limited number of patients, all these studies suggest a substantially similar efficacy of biosimilar products, when compared to originators in the febrile neutropenia prophylaxis of lymphoma and myeloma patients post-ASCT. The aim of this study was to compare the biosimilar filgrastim Zarzio with the other available formulations of granulocyte colony-stimulating factor (G-CSF) in terms of efficacy and safety [1].

Predicting the response of diabetes patients to biosimilar insulin

Biosimilars/Research | Posted 07/11/2014

For patients with type 1 diabetes, the quality of the insulin they take is a matter of life and death. The situation is similar for patients with type 2 diabetes. The question is what will these patients think about switching from their current brand-name insulins to new biosimilar versions? The question is important right now with the imminent arrival of biosimilar insulins on the market.

Biosimilars: similar but not identical

Biosimilars/Research | Posted 07/11/2014

One reason for distrust among physicians over using biosimilars in extrapolated* indications could be the fact that it is frequently cited that biosimilars are ‘similar but not identical’ compared to small molecule generics, which are often referred to as ‘identical’.
