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 But MAbs are far from an outdated technology.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…

Finding Efficiencies to Accelerate Biopharmaceutical Development

An old engineering adage says that in any technical project, you can get speed and/or quality and/or cost-efficiency — but you never get to have all three. The idea is that emphasizing any one of those parameters necessarily deemphasizes one or both of the others. For most of the biopharmaceutical industry’s early years, companies operated on that assumption. Many organizations saw speed as the weakest link that could be more or less ignored; others had money to burn. The smartest…

The Upstream Perspective: Taking Efficiency Beyond Cell-Line Development

With 20 years of experience in the biopharmaceutical industry — at Genentech, Applied Biosystems, Cell Genesys, Cellerant Therapeutics, and Bayer — Yuval Shimoni has written frequently for BioProcess International on a number of production topics. Those have ranged from process improvements and bioreactor scale-down validation, to raw materials management, to addressing variability and virus contamination events. For this featured report, we discussed hardware and instrumentation, quality by design (QbD) and related approaches, and other strategies that can take expediting upstream…

The Downstream Perspective: Putting Product Knowledge to Work Using Technological Innovations

After over a quarter century in the industry — including downstream processing (DSP) and manufacturing directorships at Boehringer Ingelheim and leadership roles in technology development, quality, and manufacturing at Novasep — European consultant Margit Holzer is a recognized expert in downstream processing of biopharmaceutical products. Holding a doctorate in biotechnology from the University of Natural Resources and Applied Life Sciences in Austria, Holzer is familiar to BPI readers as both an author and conference participant (1, 2). And in May…

The Analytical Perspective: Turning Data Into Information Requires Teamwork

As head of bioanalytics at Sanofi, Claire Davies leads a team of >90 people involved in development, qualification, and transfer of methods to internal and external commercial quality control units; characterization, comparability, and developability of proteins and gene therapies; and analytical support for up- and downstream development, production, product release, and stability testing. She has served in a number of roles over 18 years with Sanofi, from chemistry, manufacturing, and controls (CMC) leadership of preclinical to commercial products (leading and…
