Introduction: Tackling the Technical and Regulatory Challenges of Biosimilar Development

In a just a few years, the biopharmaceutical industry has gone from questioning the feasibility of “follow-on biologics” (around the time of BPI’s first issues) to fearing them (when we published our first supplement on the topic in 2013) to the acceptance and strategizing of today. Perhaps because of its more socialized medicine, Europe led the way in biosimilar regulation and approved its first such product nearly 10 years before the first US biosimilar launch in 2015. In between came…

Advancements in Characterizing Therapeutic Protein Higher-Order Structure

Electrospray-ionization mass spectrometry (ESI-MS) is a well-established tool for biotherapeutic analysis. It draws intact proteins or peptide ions into the vacuum of a mass spectrometer, where the ion mass is measured. Electrospray ion-mobility mass spectrometry (ESI-IMS) introduces ions into a low-pressure gas, where the effects of aerodynamic drag reveal their shape. This technique is just emerging as a valuable tool for characterizing intact proteins, even though for a decade it’s been the basis of a commercially available medical diagnostic test…

Biosimilar Markets and Regulation: Which Countries Are Going All In?

The pipeline of follow-on (biosimilar and biobetter) products in development for the US, EU, and other major markets is very healthy. It includes nearly 800 biosimilars, about three-quarters of which are presumed to be targeted for major markets, and about 500 biobetters in development. Nearly 1,200 follow-on biopharmaceutical products in the development pipeline are intended to compete with more than 100 currently marketed biopharmaceuticals. This is not just an opportunity in the Western world; biosimilars development is expanding globally. But…

The Clinical Side of Biosimilar Development

Biosimilars have become common on pharmacy shelves in Europe. The first biosimilar product — Sandoz’s Omnitrope version of Lilly’s Humatrope (somatropin) — was approved by the European Medicines Agency (EMA) in 2006. In the decade that followed, more than 20 biosimilars have gained regulatory approval in Europe. The first biosimilar monoclonal antibodies (MAbs) — comparators to Janssen’s Remicade (infliximab) — were approved in 2013. The pace of approvals in the United States has been much slower. The US Food and…

Evolving Bioassay Strategies for Therapeutic Antibodies: Essential Information for Proving Biosimilarity

The modern age of biologics began 35 years ago with the approval of Lilly’s Humulin product — a biosynthetic form of human insulin derived from recombinant DNA and microbial cell culture (1). Today, about a quarter (27%) of the drugs approved yearly by the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) are biopharmaceuticals: primarily monoclonal antibodies (MAbs), but also vaccines, blood products, and (recently), advanced therapies based on genes and cells. A decade ago, the average…
