The Need for Adherent Cell Manufacturing: Production Platform and Media Strategies Drive Cell Production Economics

Most commercial biopharmaceuticals originated from academic research laboratories and start-up development laboratories. Despite such products having differences in modalities and targeted disease indications, and whether their target patient populations are relatively small or approaching blockbuster status, at a key point in development, biopharmaceutical production must scale up from laboratory to commercial production. That movement from research to development and then to manufacturing forces attention on economics and speed to market, and it drives innovative approaches to producing biopharmaceutical cell compositions…

Development and Application of a Simple and One-Point Multiparameter Technique: Monitoring Commercial-Scale Chromatography Process Performance

In commercial-scale biopharmaceutical manufacturing, downstream chromatography steps are still a bottleneck and contribute to significant operational costs (1, 2). Some of those costs are inherent (e.g., resins, large buffer quantities, and cleaning) whereas others are avoidable (e.g., product loss due to rejected lots or deviations that result in production downtime). Maintaining efficient and robust chromatography process performance is therefore critical for minimizing operating costs. To do so, we introduce a simple and one-point multiparameter technique (SOP-MPT) for monitoring chromatographic process…

Speeding Characterization of Biologics: Replace Traditional Assay Technologies with Label-Free Quantification and Kinetics

FortéBio’s Octet instruments are an ideal replacement for ELISA, HPLC, and SPR techniques in quantification of antibodies and recombinant proteins and in testing product potency for lot release. Bio-Layer Interferometry (BLI) technology monitors biomolecular interactions in real time to determine affinity, kinetics, and concentration. The plate-based, microfluidics-free format offers users several distinct advantages over other technologies. BLI-based systems can achieve higher throughput, with the flexibility to measure two to 96 samples simultaneously. Lower maintenance requirements and increased ease-of-use further shorten…

Elucidation: Changes in VA Healthcare Pose New Implications for Drug Companies

Veterans of the US military still struggle to access healthcare despite the 2014 congressional passing of the Veteran’s Choice Program (VCP), a US$10 billion-dollar “fix” that allows qualifying veterans to see community physicians who have contracted with the Department of Veterans Affairs (VA) to provide care. Veterans who enrolled in VCP to avoid long wait times at department medical facilities still have faced month-long delays before seeing a doctor, according to a 2018 GAO report. Investigators have found that the…

Ask the Expert November: Expediting Characterization and Maximizing Reliability of Process Validation

On 24 October 2018, BPI presented a free “Ask the Expert” webinar with Abel Hastings, director of process sciences at Fujifilm Diosynth Biotechologies. He discussed the use of systematic tools to expedite process characterization and maximize reliability of process validation campaigns. Hastings’s Presentation As a project moves from clinical manufacturing toward process validation — and ultimately toward preapproval inspections — project timelines can become hypervisible at all levels of an organization. Missteps can be costly. The commercial viability of a…

Ask the Expert November: Improving CHO-Cell Biomanufacturing with a Whole-Genome CRISPR Screening

On 18 October 2018, BPI presented a free “Ask the Expert” webinar with Jamie Freeman, a bioproduction product manager at Horizon Discovery. His company is developing a whole-genome screen using clustered regularly interspaced short palindromic repeats (CRISPR) for improving the capacity of Chinese hamster ovary (CHO) cells in biomanufacturing. Freeman’s Presentation Freeman described the screening approach that Horizon developed to improve its own CHO cells. It also may be used to improve other such cell lines for biomanufacturing. Founded 11…

Ask the Expert November: New High-Performance AEX Resin for Purification of Large Biomolecules

On 20 September 2018, Jiali Liao (principal scientist in process chromatography R&D at Bio-Rad Laboratories) led a BPI “Ask the Expert” webinar introducing the high-performance, high-capacity Nuvia HP-Q Anion Exchange Resin, which can be used for purifying large biomolecules. Liao’s Presentation Purifying large biomolecules — e.g., plasma proteins, immunoglobulins, viruses, virus-like particles (VLPs), and PEGylated proteins — can be difficult. Their size makes for slow diffusion through the pores of traditional chromatography resins and poor mass-transfer kinetics, which decreases binding…

Manufactured by Jetting: The Future in Protein A Affinity Matrix Design

Protein A affinity chromatography continues to be the preferred method for commercial purification of antibodies because of its high selectivity and robust resin performance over repeated purification cycles. Reports estimate that US$125 billion of yearly sales will be generated from monoclonal antibody (MAb) products by 2020 (1). Most of those will be purified by largescale protein A affinity chromatography. With the continued growth and commercial importance of MAb production, availability of high-quality resin material and options for secondary sourcing are…

Cell Culture Scale-Up in Stirred-Tank Single-Use Bioreactors

Bioprocess development usually is carried out in systems with small working volumes. This helps save time and resources because, at small scale, several experiments can be conducted in parallel. Costs for media are kept low, and relatively little laboratory space is required to operate small-scale bioreactors. But over the course of development, biopharmaceutical companies need more material for characterization, trial runs, and finally for commercialization. They transition to bench scale and then up to pilot or production scale with the…
