Biopharmaceutical Fill and Finish: Technical and Operating Challenges for the Latest Formulations and Devices

Because they occur after two highly engineering, and science-driven phases of biomanufacturing – expression and purification – biopharmaceutical fill and finish processes have not received the respect traditionally that they deserve. Yet of all competencies associated with bringing biopharmaceuticals to market, fill and finish arguably are the most specialized. This eBook reports on the technical and operating challenges impacting the latest formulations and devices including: outsourcing, contamination, standardization (pre-filled syringes), lyophilization, and serialization. Get informed on the current state-of-the-art technologies…

Special Report on Antibody-Drug Conjugates: Technical Challenges and Opportunities

Among the emerging targeted therapies in biotechnology, antibody–drug conjugates (ADCs) hold a unique position. An ADC consists of a monoclonal antibody (MAb) with affinity to tumor cells, a cytotoxic small-molecule payload, and a linker connecting the two. Together the MAb, conjugation chemistry, and cytotoxin increase the complexity of ADCs several-fold relative to unmodified MAbs — and exponentially relative to chemotherapies. Viewing ADCs as hybrids of antibody- and chemotherapy-based cancer therapies is tempting. That description applies chemically and structurally, but ADCs’…

Special Report: A Strategy for Cost-Effective Capture Using Agarose-Based Protein A Resins

It is well recognized that the cost of Protein A resins is substantial. If a developmental monoclonal antibody (MAb) makes it to marketing approval and manufacturing, the high cost of purification using a Protein A resin is amortized over a large number of purification cycles, and the contribution to cost of goods is reduced to acceptable levels. However, a high percentage of clinical projects will fail, and the Protein A resin will be used only for a small number of…

Special Report on Continuous Bioprocessing: Upstream, Downstream, Ready for Prime Time?

Once an engineering curiosity and smallscale laboratory technique, continuous bioprocessing has evolved in just a few short years to a topic of intense and increasing interest to most bioprocessors. Critics point to a steep learning/adoption curve, but that is nothing new in biomanufacturing.Andrew Zydney is a distinguished professor of chemical engineering at Pennsylvania State University. He has noted these challenges facing continuous processing: commercially unproven unit operations (especially downstream), a lack of equipment robustness, sterility concerns, and uncertain development timelines…

Cancer Immunotherapies: Fulfilling the Promise of Protein and Cell Therapies

With few exceptions, both small-molecule and biological cancer treatments have contributed only incrementally towards achieving long-term responses or outright cures. In this regard, emerging cell- and protein-based cancer immunotherapies represent game-changing strategies for treating even refractory cancer. With long-term responses now possible, medical science may be on the verge of delivering on the long-unfulfilled promise of making cancer a manageable disease. But impediments to commercializing cancer immunotherapies are substantial. Producing cell-based treatments entails substantial hands-on manipulation and perfecting the logistics…

CMC Strategy Forum Special Focus Series: Part 2 Product-Related Impurities, An Overview

Introduction by Cheryl Scott The CMC Strategy Forums focus on relevant chemistry, manufacturing, and controls (CMC) issues throughout the life cycle of a therapeutic and thereby foster collaborative technical and regulatory interaction. Forum chairs share information with regulatory agencies to help them merge good scientific and regulatory practices. Outcomes of forum meetings are published in BioProcess International and on the CASSS website. This process is meant to help ensure that biopharmaceutical products manufactured with advancing technologies in a regulated environment…

Special Report: Toward Sustainable Engineering Practices in Biologics Manufacturing

Introduction by William P. Flanagan Biopharmaceutical development and manufacturing demand scalable processes that can be quickly developed, easily implemented, and smoothly transferred to production. Disposable, ready-to-use technologies play a crucial role in providing flexibility to support agile biomanufacturing operations. Single-use systems provide process efficiencies by removing steps such as cleaning and cleaning validation, thus allowing for faster change-over between manufacturing runs. The biopharmaceutical industry is increasingly adopting single-use approaches, and the global market for such bioprocessing tools is expected to…

Process economy and production capacity: Comparing single-use and stainless steel strategies for microbial fermentation

In recent years, single-use technology has been migrating into many unit operations.  With the commercial availability of such systems end users have a new option for process development and production that does not rely on operational complexities and utility requirements of conventional sterilize-in-place (SIP) or autoclavable systems. However, just as for cell culture processes, single-use technology may not apply to each and every fermentation or microbial process.  It is the responsibility of practitioners to properly assess their own applications, select…
