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?

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

Biopharmacological studies, including biosimilar studies, require investigation of the higher order structure of proteins. A recent review published in GaBI Journal (GABIJ) [1] has found that, although many analytical methods to determine the higher order structures exist, spectroscopic methods remain the most used.

Phase III trial updates of Samsung Bioepis’ bevacizumab and aflibercept biosimilars

Samsung Bioepis has reported positive results from a phase III trial of its bevacizumab biosimilar, Aybinto. The company is also initiating a phase III trial for its aflibercept biosimilar, SB15.

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 allow fast access to biological drug therapy in Bavaria, Germany

Biosimilars/Research | Posted 18/09/2020

A new study has shown that patients suffering from rheumatism in Bavaria, Germany, are now likely to be prescribed a biological medicine much faster than five years ago. Results of the study were shared at the AG Pro Biosimilars digital symposium on 14 September 2020.

What oncologists do not understand about biosimilars

Biosimilars/Research | Posted 18/09/2020

The availability of biosimilars may improve access to health care by increasing the number of therapeutic options available at potentially lower costs. However, based on the results of multiple surveys of many healthcare providers (HCPs) conducted in recent years, clinicians appear wary of prescribing biosimilars.

Budget savings from biosimilar infliximab in the UK, France, Japan and Korea

Biosimilars/Research | Posted 11/09/2020

Biological medicines are attracting attention from policymakers and health insurers across countries due to their increased financial burden. The potential for biosimilars’ cost savings can be influenced by various factors, including supply-side (pricing policies) and demand-side (usage-enhancing) policies.

Celltrion’s biosimilars effective against gastric cancer and B-cell lymphoma

Biosimilars/Research | Posted 11/09/2020

Recent clinical trial results confirm that Celltrion’s biosimilars Herzuma (trastuzumab) and Truxima (rituximab) are effective in the treatment of gastric cancer and B-cell lymphoma, respectively.

Monoclonal antibody biosimilars and cancer in the EU

Biosimilars/Research | Posted 04/09/2020

Spanish researchers investigated the current status of biosimilar monoclonal antibodies (mAbs) in the European Union (EU) by reviewing the regulatory pathway, the rationale for extrapolation and switching and the current status and future perspectives of the biosimilars approved in the EU [1].
