eBook: Antibody–Drug Conjugates —
A New Generation of Approaches Is Changing the Game

by , , and

Combining large proteins with linkers and cytotoxins, antibody–drug conjugates (ADCs) may be the most complex drug molecules in development today. Despite early promise and product approvals, a number of technical concerns arose during product and process development. Characterizing and ensuring consistency in the number of small molecules that attach to the antibody — as well as ensuring their proper attachment and biophysics — all present significant challenges to ADC developers. Solving early problems associated with product quality has introduced a…

Tris, a Critical Raw Material: Improving the Quality and Consistency of Supply

by

ANGUS Life Sciences is the world’s largest supplier of tromethamine buffers and the only manufacturer of the tris molecule based in the Western hemisphere. The company sells directly to biopharmaceutical customers and contract manufacturing organizations as well as to reprocessors who repackage the chemical or process it into different grades and derivatives. After recent expansions in both the United States and Germany, the company now boasts dual-source manufacturing capabilities for its highest-purity tris products and is confident about its ability…

Realization of Quality By Design and Beyond: The Intelligent Cell Processing System

by , and

Cells are used as raw materials, intermediates, and final products in biopharmaceutical and cell therapy manufacturing. Because living cells are always in a dynamic state, their characteristics must be kept within specified ranges throughout bioprocessing to preserve their utility. Cell population expansion without changing the original cell properties is key for obtaining the required number of cells at the next step. However, limited process data are collected during the expansion phase — information that could be used to understand and…

Get High-Throughput, Definitive Identification of Viable Cells and More in Your Cell Therapy

by , and

Analyzing for viable cells using traditional methods such as flow cytometry often encounters clogging resulting in the loss of precious cell therapy samples. Not only is it low throughput, but incredibly complicated, which can lead researchers to misidentify cellular and non-cellular material and confuse cell viability results with product-purity issues. Additionally, it is a regulatory requirement for all injectable drug products be characterized for sub visible particles (SVP) and aggregates that may form during a manufacturing process. With Backgrounded Membrane…

Addressing Critical Issues in Cell and Gene Therapy Manufacturing

by

Recombinant lentivirus (LV) and adeno-associated virus (AAV) are critical components of cell and gene therapies, which show great promise for treatment of diseases from genetic disorders to cancer. Accordingly, there is an unprecedented need for high titer and large-scale viral vector manufacturing processes to support the growing number of researchers developing biotherapeutics for immunotherapy. Download this Special Report, highlighting: Evolutions of gene therapy manufacturing Improvements to GMP raw-material sourcing. Role of transfection reagents like VirusGEN® GMP as a turnkey element…

The Green Imperative: Part 3 — Postuse Management of Single-Use Bioprocessing Materials, Today and Tomorrow

by , , , , , , and

The world desires a more sustainable economy in which resources can be saved, products can be profitably used, and at the end of their useful life, component materials can be recycled into other useful products. The bioprocessing industry has made efforts to meet those goals and has learned a great deal about the role of plastic components in sustainable manufacturing. The most important lesson might be that a science-based approach is required to provide an accurate benchmark of manufacturingʼs environmental…

Formulation, Fill and Finish of Lentiviral Vectors Part 2: Key Decisions and Risk Management

by and

Over the past few years, Oxford Biomedica UK has developed and implemented its fill–finish platform at its 84,000-ft2 “Oxbox” manufacturing facility constructed in 2019. The first phase of development (45,000 ft2) houses four segregated suites for producing bulk viral-vector drug substance (VS) where closed systems and bioburden-control processes apply, and two fill–finish suites for viral-vector drug product (VP) in aseptic processing. The first of the fill and finish suites is expected to be approved in the first half of 2022.…

eBook: Creating CMC Strategies for Pandemics and Beyond — Perspectives on the Impact of the COVID-19 Pandemic

by , , , , and

The COVID-19 novel coronavirus pandemic has highlighted the biopharmaceutical industry’s need to create and implement chemistry, manufacturing, and controls (CMC) strategies that can expedite drug development during times of crisis. This bold topic was the premise of the 2021 CASSS Well-Characterized Biotechnology Products (WCBP) forum titled “Special Edition: Creating CMC Strategies for Pandemics and Beyond.” Held virtually on 25–28 January and 1–4 February 2021, the eight-day event addressed manifold considerations for SARS-CoV-2 virus prevention, diagnosis, and treatment. Five hundred attendees…

eBook: Cell and Gene Therapies — Optimization Strategies for Processing and Potency

by

Although relatively new to the biopharmaceutical industry, cell and gene therapy development and manufacturing are advancing rapidly. At Informa Connect’s September 2021 Cell & Gene Manufacturing & Commercialization Conference and Exhibition, held in Boston and online, presentations reviewed concerns that arise when processing complex therapies and highlighted some innovative strategies for surmounting those obstacles. Most of those approaches described during the event used data-driven solutions, with each step building on the information gained from the previous one. High-throughput technology platforms…

eBook: Vaccines Revisited — The Past, Present, and Future of Nucleic-Acid Vaccine Production

by , and

The quarterly BioProcess Insider eBook series launched in 2021 to investigate specific modalities and business strategies driving the biopharmaceutical sector based upon trends and discussion points presented in the Insider’s pages. Two of the four quarterly publications — this one included — have focused on the vaccine industry. If the series had launched in 2019, cell and gene therapies might have warranted a double edition, or perhaps investments in antibodies and antibody fragments would have driven a bispecific focus. Five…
