eBook: mRNA — Negotiating New Manufacturing Hurdles

The emergency authorization, regulatory approval, and successful commercialization of Pfizer–BioNTech’s and Moderna’s respective mRNA vaccines for SARS-CoV-2 have ignited considerable interest in the modality across the biopharmaceutical industry — and for good reasons. Establishing a platform process for mRNA production could facilitate and accelerate several aspects of vaccine development and manufacturing. Drug makers also intend to leverage benefits associated with cell-free bioprocessing. But as the contributors to this eBook show, mRNA remains a nascent modality, and companies must surmount new…

Introduction: Viral Clearance and Inactivation in Downstream Processing

Viral safety in the biopharmaceutical industry is both an upstream-production and downstream-processing concern. Companies must take a multipronged approach using orthogonal methods that are validated to prevent viral contamination or to remove it from biologic drug products. On the upstream side, the focus is on prevention through risk assessment and mitigation. That begins with environmental control of facilities and includes both careful selection of raw materials and cell lines and preparatory filtration of culture media components. In downstream processing of…

eBook: Chromatography Column Packing — Best Practices and Considerations from Laboratory to Manufacturing Scale

Column chromatography is a powerful separation tool for biopharmaceutical research and industry, with applications ranging from laboratory bench-scale purification to process development and commercial-scale manufacturing of biotherapeutics. Ensuring the highest quality of separations depends on many factors, including the technique used for packing the chromatography column. Well-packed columns provide for the best chromatographic separations. Successful column packing ensures proper mobile-phase distribution and resin contact. Scaling up to large columns can introduce many challenges. Manufacturers of chromatography media provide best-practice advice…

September 2022: From the Editor

Just coming off our big anniversary issue, we editors are still in a taking-stock mindset. That normally goes hand-in-hand with planning for the next publication year — which we can’t believe we’re doing already — but it feels more acute this time. And our 20th year has coincided with some pretty major current events, as the world begins to emerge from a pandemic amid a great deal of associated economic and sociopolitical turmoil. The effects of it all on the…

Hardware, Software, and Wetware: 20 Years of Advancements in Biopharmaceutical Production, Part 2

The past couple of decades have witnessed significant advances in upstream bioprocess technologies and approaches. Since its establishment, BPI has been a facilitator of discussion both in print and at professional conferences, as well as in webcasts and news online. To mark the 20th anniversary of the publication, we surveyed articles published over the past two decades and found hundreds that highlight significant advances in both emerging and established themes in biopharmaceutical production: • “hardware” technology (e.g., analytical instrumentation, bioreactors,…

20th Anniversary Issue: From the Editors

Founded in the middle of 2002, BPI published its first issue in January of 2003. Our 20th-anniversary issue thus takes the form of a state-of-the-early-21st-century industry report. Assembling this content has reinforced our appreciation of the remarkable paths that this industry has taken and continues to take — and our journey alongside it. Having worked as editors in this industry since August 1988 (Montgomery) and September 1996 (Scott), we’ve found it difficult to maintain a chronological grasp of developments —…

20 Years of Chemistry, Manufacturing, and Controls Strategy. A Conversation About the CASSS CMC Forum Series

Formerly known as the California Separation Science Society, the CASSS organization has maintained a close relationship with BioProcess International since its inaugural year. In particular, the CMC Strategy Forum series began the same year that BPI’s original staff joined Informa to develop a new international trade publication covering biopharmaceutical development and manufacturing. Beginning with our February 2004 issue, BPI has been proud to publish dozens of reports from this influential series of meetings over the years. Their success around the…

The Ultimate Business Continuity Challenge: A Case Study in Ukraine

The past few years have taught people around the world that “It can’t happen here” is never a good bet. From the COVID-19 pandemic to political upheavals to Russia’s invasion of Ukraine, we’re all experiencing a reality that would have seemed impossible not so long ago. And as numerous analysts and experts discuss on television and social media and in other publications what such events could mean politically and socially, we at BPI must maintain our focus on the biopharmaceutical…

Introduction: Cell-Line Engineering and Development at BPI West

Critical to the manufacturing of biotherapeutics is development of robust and stable cell lines that express high-quality products in large quantities. Chinese hamster ovary (CHO) cells are the “workhorse” expression host for manufacturing glycoprotein-based therapeutics — from antibodies to enzymes and hormones and beyond — making them the subject of most industry discussion regarding both cell-line development (CLD) and engineering. Most methods, technologies, and strategies apply regardless of the type of protein to be expressed or the type of cells…
