Shared decision-making and the transition to biosimilars

Biosimilars/Research | Posted 06/11/2020

Increasing healthcare cost are forcing health authorities to look for low-cost innovations to help bend the cost curve. Biosimilars, a biotherapeutic product which is similar in terms of quality, safety and efficacy to an already licensed reference biological, are such an innovation [1]. Because biosimilars are often offered at lower prices, their use has been promoted all across the world. The initiating of biosimilars in bio-naïve patients is already commonplace in many countries. However, the transitioning from originator biological to its biosimilar for non-medical reasons is still debated. Different strategies about how and when to transition are formulated and applied.

Role of efficacy trials in biosimilar assessments questioned

Biosimilars/Research | Posted 30/10/2020

In recent years, the role of the comparative efficacy trial in biosimilar assessments has been brought into question. This is explored in a recent article published by Bielsky and colleagues [1].

Perceptions of biosimilars and switching in Arab rheumatologists

Biosimilars/Research | Posted 30/10/2020

The introduction of biosimilars into the rheumatology field could lead to dramatic cost savings as has been observed in certain European countries. Their implementation and acquisition, however, is not the same across the world. Many rheumatologists have developed a negative perception toward biosimilars and the process of non-medical switching. As important stakeholders, their views and concerns need to be addressed to ensure an effective introduction of these therapeutic agents. Mohammed Omair and colleagues evaluated how Arab rheumatologists perceive biosimilars in view of understanding the manufacturing and approval process during the Arab League Against Rheumatism Conference (ArLAR) [1].

Biosimilar assessments: do we need efficacy trials?

Biosimilars/Research | Posted 23/10/2020

Regulatory guidelines for biosimilar approval have existed in Europe since 2004. These are based on the totality of evidence from comparative studies with reference products and have always required comparative efficacy studies. However, a recent article by Bielsky et al., published in Drug Discovery Today [1], explores the increasingly questioned role of the clinical efficacy trial in biosimilar approval.

Biopharmaceuticals and biosimilars: manufacturing challenges

Biosimilars/Research | Posted 23/10/2020

Clinical review of biosimilars approved in oncology

Biosimilars/Research | Posted 09/10/2020

As cancer therapeutics constitutes a large proportion of the biologicals market, and patents have begun to expire, biosimilars have an important role in optimizing patient access and reducing costs in the oncology therapeutic area. Authors Ngo and Chen from the City of Hope National Medical Center, Los Angeles, USA, give an overview of the US Food and Drug Administration (FDA)-approved biosimilars in oncology and their impact on the healthcare system in the Annals of Pharmacotherapy [1]. A summary of the main findings from that article follows.

Biopharmaceuticals and biosimilars: challenges in manufacture, regulation and international harmonization of GMP

Biosimilars/Research | Posted 09/10/2020

Biopharmaceuticals are large molecules that are far more complex than traditional, chemical pharmaceuticals. With patent expiry for many originators, biosimilar versions are expected to flood the market in the years to come. However, the active pharmaceutical ingredients (APIs) of all such products are manufactured using living systems which means that their manufacture and characterization is also complex.

Why biosimilar applications fail during regulatory evaluation?

Biosimilars/Research | Posted 02/10/2020

The patent expirations of many blockbuster biologicals have paved the way for development of biosimilars and this has the potential to enhance access to otherwise high-cost biological therapies. Given the complexity of biologicals, the regulatory guidelines for biosimilar approval are meticulous and different from generics. Hence biosimilar developers often face issues during the application evaluation by regulatory authorities. With large number of biosimilars in development stage, it is pertinent for a manufacturer to have a deep understanding of the regulatory approval process. Rathore and colleagues from the Indian Institute of Technology offer insights into the objections raised by the regulatory authorities during evaluation of biosimilar applications for marketing authorization with special emphasis on applications reviewed by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA).

Spectroscopy remains dominant when investigating biosimilar structures

Biosimilars/Research | Posted 02/10/2020

FDA to investigate PD biomarkers to show biosimilarity

Biosimilars/Research | Posted 25/09/2020

The US Food and Drug Administration (US FDA) is conducting research on critical aspects of the use of pharmacodynamic (PD) biomarkers to demonstrate biosimilarity. A study published in Clinical Pharmacology and Therapeutics, has outlined how the agency hopes to inform their thinking on critical aspects of how these biomarkers can be used to reduce the need for comparative clinical studies [1]. In turn, this can reduce the time and cost of bringing a biosimilar product to market, giving faster access to affordable, safe, and effective treatments.

Biosimilars in Belgium: increasing competition

Biosimilars/Research | Posted 03/07/2020

Competition following the entry of biosimilars is still limited in Belgium, which is mirrored in low biosimilar market shares. Although (short-term) cost savings are realized by the implementation of mandatory price reductions on originator medicines (and obtaining high biosimilar market shares should thus not be a goal in itself), biosimilars can play a key role in ensuring the long-term sustainability of the Belgian off-patent biologicals market.

Use of anti-TNF biosimilars in the US

Biosimilars/Research | Posted 03/04/2020

Uptake of biosimilars in the US is slow to say the least. In fact, biosimilars currently make up only 2.3% of the US biologicals marketplace [1]. Researchers from the US therefore investigated whether anti-tumour necrosis factor (anti-TNF) biosimilars are realizing their promise to increase competition and improve accessibility in the US [2].
