BioProcess International 2019 Event Report

by , , , and

The 2019 BioProcess International Conference and Exhibition, held in Boston, MA from 9–12 September, was a testament to the rapid expansion of the biopharmaceutical industry. Nearly 150 speakers chronicled recent developments and continuing challenges in upstream production, downstream processing, drug product manufacturing, and emerging therapies production. And with more than 150 poster presentations and over 200 companies participating, the BPI exhibit hall never better embodied the industry’s efforts to support increasingly diverse but related audiences. In this event report, BioProcess…

eBook: Bioassays for Biopharmaceuticals: Finding Best Practices in a Quality Systems World

by , and

Bioassays are complex and challenging experiments to run reliably with accurate and dependable results. Consistent performance requires a controlled environment and qualified reagents; skilled analysts who understand cell physiology, regulatory requirements, and the latest techniques; and assay protocols that are intelligently developed, characterized, and validated. Here, BPI’s senior technical editor discusses bioassay best practices with representatives of the Biopharmaceutical Emerging Best Practices Association (BEBPA) organization. Topics span quality by design, assay validation, cell banking, potency testing and host-cell protein monitoring,…

eBook: Bioreactor Scale-Up: From Pilot to Commercial Scale in the Modern Era

by and

Upstream bioproduction always has begun with laboratory systems producing limited amounts of product for test purposes, then those bioprocesses are scaled up to make more product more efficiently for larger clinical trials — and ultimately commercial distribution. With the advent of single-use technology and continuous processing, how have scale-up approaches changed in recent years, specifically at the pilot-to-production level? In this online exclusive, BPI editors review the science and technology affecting decisions made at this stage of process development, with…

Introduction: Reporting from the Frontiers of Cell Line Engineering at BPI Europe and BPI West

by

Every biomanufacturing process begins with transfection of recombinant genes into pools of cells — followed by a succession of screenings from which will emerge (ideally) a single progenitor cell of the new production cell line. Cast aside will be those cells that do not uptake the correct genetic material, those incapable of thriving in bioprocess conditions, those that fail to produce recombinant protein at relevant levels, and those without demonstrated clonality and relative genetic stability. Over the past several years,…

From the Editor — September 2019

by

Our readers, authors, and advertisers often are surprised to discover that the magazine you hold in your hands (advertisements aside) represents primarily the work of three people. The BPI editors are multitaskers and jacks-of-all-trades by necessity. Every month we all seek out authors and work with them to develop their manuscripts . . . copyedit their texts and typeset the results . . . research, interview, and write our own articles . . . adapt and develop graphics . .…

Toward Standardized Sample Collections: UK Government Seeks to Expand Cell and Gene Therapy Use

by

The SAMPLE program — a Standard Approach to ATMP Tissue collection — is intended to help build capacity for the UK National Health System (NHS) to expand the use of next-generation cell and gene therapies for both cancer and noncancer illnesses. Now it has been given the green light by Innovate UK (IUK), the United Kingdom’s technology strategy agency. An award through the Industrial Strategy Challenge Fund is supporting the program for standardizing how cell and gene samples are collected…

Biopharmaceutical Characterization, Part 2: Applications and Strategies for Diverse Products — A Conference Report

by

Last fall, KNect365 brought together more than 250 analytical specialists to discuss biological assays and characterization of well-characterized biologics in Rockville, MD. Speakers from the US Food and Drug Administration joined experts from leading biopharmaceutical companies, service providers, and consultancies for case studies, regulatory interactions, sharing perspectives, and learning about emerging technologies. Part 1 of this report in January 2019 focused on the bioassay section of the meeting. Here in Part 2 sponsored by Sartorius, BPI’s senior technical editor reports…

Large-Scale Capacity Strategies: Single Use, Multiuse, or Both?

by

Early manufacturing facilities for large-scale production of biopharmaceuticals were, by necessity, very large. Low expression titers and blockbuster-market products such as monoclonal antibodies (MAbs) combined to require massive bioreactors — with capacities of 10,000– 20,000 L or more — and supporting infrastructure. In my early days covering the industry, I visited a few such facilities and was always awed by the huge tanks and what seemed like miles of piping. A 2010 Pharmaceutical Engineering article described a process modeling approach…

June 2019 – From the Editor

by and

Often we are pleasantly surprised at thematic connections that fall within an issue or come between an issue and its supplements — sometimes planned, sometimes a matter of happy coincidence. Setting an issue theme of continuous processing with a featured report on large-scale capacity strategies inevitably created some overlap. At this stage of maturation in its brief history, the biopharmaceutical industry offers myriad choices for facility design, process development, manufacturing paradigms, and partnering arrangements. With many successful examples to choose…

Making Downstream Processing Continuous and Robust: A Virtual Roundtable

by , , , , , and

Current biomanufacturing is driven to pursue continuous processing for cost reduction and increased productivity, especially for monoclonal antibody (MAb) production and manufacturing. Although many technologies are now available and have been implemented in biodevelopment, implementation for large-scale production is still in its infancy. In a lively roundtable discussion at the BPI West conference in Santa Clara, CA (11 March 2019), participants touched on a number of important issues still to be resolved and technologies that are still in need of…
