Improving CHO Cells for Biomanufacturing

Chinese hamster ovary (CHO) cells have been used in biomanufacturing for decades because of their robust capacity to express a range of proteins, such as therapeutic enzymes and monoclonal antibodies (MAbs) at titers measured in multiple grams per liter of culture. Within the available suite of CHO cell lines, the glutamine synthetase knockout (GS-KO) selection system provides industry-leading speed to the identification of high-producing clones for use in biomanufacturing. The GS-KO selection system allows for identification of multiple-gram/L clones in…

The projects include an Overview, Developments in Biologics, Biosimilars, and Global Expansion. The series…

FDA pledges to support cell and gene therapy manufacturing innovation

Manufacturers aiming to follow Yescarta and Kymriah to market can count on FDA support after the agency said it will help cell and gene therapy firms adopt better production methods. A US Food and Drug Administration (FDA) spokesman told Bioprocess Insider the agency’s emerging technology team has been tasked with working with cell and gene therapy firms to “identify innovative approaches for efficient product manufacturing.” The move is part of a wider FDA effort to support modernization of drug manufacturing…

Opportunities for Modern Robotics in Biologics Manufacturing

It should come as no surprise to anyone familiar with biomanufacturing that current designs of bioprocess facilities as well as associated manufacturing spaces and support operations require excessive amounts of manual labor and manual interventions that lead to high labor costs and, consequently, total cost to supply. From receipt of raw materials to process execution and performance review, resolution of quality issues, and product shipping, no industry devotes a greater percentage of operating costs (or cost of goods sold, CoGS)…

The Role of Single-Use Polymeric Solutions in Enabling Cell and Gene Therapy Production: Part 1: Introduction and Manufacturing Process

by Bio-Process Systems Alliance Cell and Gene Therapy Committee The Bio-Process Systems Alliance (BPSA) was formed in 2005 as an industry-led international industry association dedicated to encouraging and accelerating the adoption of single-use manufacturing technologies used in the production of biopharmaceuticals and vaccines. Corporate members include plastic-equipment suppliers, service providers, and users in the biopharmaceutical industry who share this mission. A key focus of BPSA’s core activities is to educate its members and others through sharing of information and development…

Cell and Gene Therapy Data Management: Solutions to Address Complex Challenges

At the Phacilitate Leaders World and World Stem Cell Summit 2019, held 22–25 January, Steve Goodman (head of drug product manufacturing at bluebird bio) and Robert Di Scipio (CEO of Skyland Analytics) shared the podium to address what the product and process data-management ecosystem looks like for cell and gene therapy (CGT) development and manufacturing. A starting point for their presentation was that CGT development presents significant data challenges: capturing and analyzing product development and manufacturing data, tracking the collection,…

Monoclonal Antibodies: Beyond the Platform in Manufacturing

The vast majority of monoclonal antibody (MAb) production processes are based on fed-batch Chinese hamster ovary (CHO) cell culture and protein A affinity column chromatography capture. Increasing cost-consciousness — among innovator companies as well as biosimilar makers — has many companies looking “beyond the platform” for less expensive alternatives that may provide better results. Here the BPI editors review some state-of-the-art alternatives in upstream and downstream MAb drug substance bioprocessing as well as drug-product manufacturing. The current “gold standard” platform…

China Can Be Ignored No Longer: Long-Term Biopharmaceutical Opportunities Based on Near-Term Demonstrated Growth

China has long served as “the world’s factory,” but many experts in the biopharmaceutical industry have assumed that making consumer electronics, clothing, and toys for a global consumer base does not translate well to making complex biologics on the global stage. However, according to a newly released report, the biopharmaceutical market in China reached a value over US$9 billion in 2018, with the domestic monoclonal antibody (MAb) market there making up a very large percentage of that (1). Much of…
