eBook: Formulation, Fill–Finish — Biopharmaceutical Drug-Product Trends and Technologies

As with many other aspects of biopharmaceutical development, evolving technologies are transforming drug-product development and manufacturing. In a November 2020 report on the Informa Connect “Drug Delivery Partnerships” meeting, BPI senior technical editor Cheryl Scott reviewed how new delivery-device technologies are bringing together companies with disparate expertise to serve patients with chronic conditions better than ever before. The ever-increasing capabilities of electronics and information technology (IT) not only are enabling development of “smart” delivery devices, but also improving the potential…

eBook: Ion-Exchange Chromatography for Modern Biopharmaceutical Purification

Understanding the functionalities of chromatography resins can improve the product yield and purity in a biotherapeutic purification workflow. Ion-exchange (IEX) chromatography separates biomolecules on the basis of charge. For several reasons, it is the most widely used separation tool for purification of biopharmaceutical products. IEX is a well-characterized purification method with high binding capacity and flexible selectivity. It also works with mild operating conditions that help to preserve the biological activity of a biopharmaceutical drug substance. That versatility enables several…

November–December 2020:
From the Editors

As 2020 draws to a close, we can’t help looking back at this year in which the biopharmaceutical industry has received more attention than ever before — scientifically, politically, and otherwise. We editors always have been conscious of (and pretty good at) separating our work and home lives. As many of you have learned this year, that’s an important part of working from home, which we’ve been doing for over a decade. But in recent months, reading the news and…

Analytical Support for Biologics: A Conversation with Almac Sciences

Almac Sciences (a member of the Almac Group) recently expanded its suite of analytical solutions to include biologics testing. This follows a 2019 expansion of the company’s facility in Athlone, Ireland, where it provides a comprehensive range of flexible pharmaceutical testing services to support drug development programs adhering to industry regulations and good manufacturing practice (GMP) standards. “Biologics have gained huge traction in the past decade and are poised for stronger growth in the coming years with potential to significantly…

eBook: Drug Delivery —
Partnerships Are Key As Medical and Digital Worlds Converge

Drug delivery is advancing into a digital future. Information technology is changing aspects of every operation in the biopharmaceutical industry. Meanwhile, machine learning and cloud computing are not only finding their way into drug development, manufacturing, and distribution, but also into drug-product delivery devices themselves. As a result, many biopharmaceutical companies are seeking medical device expertise through strategic alliances and contract services. New delivery devices can help big companies extend patent protection on established marketed products, for example, and provide…

Making MAbs: Bioprocess Advancements Challenge Platform Assumptions

Still the largest sector of the industry, monoclonal antibodies (MAbs) have dominated the biopharmaceutical stage for over 30 years. Some observers might think there’s nothing new to say about these molecules; others point to antibody derivatives as a more exciting alternative. But MAbs are far from an outdated technology. From biosimilar developments to cell-free synthesis to yeast display, immunogenicity improvements, and fully human antibodies — as well as improvements in process efficiency and cost reductions, as discussed herein — the…

eBook: Mixed-Mode Chromatography for Purification of Biopharmaceuticals

Mixed-mode chromatography offers several advantages in downstream processing of biotherapeutics. Mixed-mode chromatography resins use ligands that are capable of at least two modes of interaction with solutes such as hydrophobic, ion exchange, and metal affinity. The interactions between stationary and mobile phases that result from those combinations enhance chromatographic selectivity, facilitating separation efficiencies that are not possible using other chromatography media. As this eBook illustrates, the multimodal approach can save developers time and money by enabling robust purification of biopharmaceuticals…

Endotoxin Questions and Answers

Endotoxin — also known as lipopolysaccharide (LPS) — is a large molecule made up of a lipid and a polysaccharide portion found in the outer membrane of each Gram-negative bacterial cell. Examination of endotoxins is necessary for microbial and animal cell-culture operations that produce active pharmaceutical ingredients (APIs) and vaccines. If a cell culture is contaminated with endotoxins, it could affect cell growth and function (thus potentially affecting product quality). Biopharmaceutical companies need to understand the endotoxin levels within their…

September 2020: From the Editor

I’m writing this from the height of our pandemic summer, and you’re reading it in the fall — in this strange year of time flying while seeming to stand still. We editors have worked from home for years, so our lives haven’t changed as much over the past few months as yours might have. Our Informa conference organizers, however, have seen their jobs transform radically. They’ve managed to pivot deftly toward virtual events, and I hope you’ve enjoyed some of…

eBook: Formulation, Fill, Finish ⁠— Biopharmaceutical Drug Products for a Modern Age

Biopharmaceutical drugs are increasing in sophistication, requiring technological advancements to solve related challenges. The contributors to this BPI eBook highlight drug-product formulation concerns and collaborative efforts toward solving the fill–finish conundrum. First, the BioPhorum’s Scott Ewan describes a holistic approach to container–closure integrity and the organization’s work toward developing and expanding upon that approach. Ewan explores how advancing analytical technologies, risk management, and quality by design (QbD) are changing the strategies related to container–closure integrity, which remains a significant aspect…
