Although chromatography remains the backbone of downstream workflows, selecting appropriate technologies to optimize processes can be challenging. Numerous resin options are available, and the fact that most biologics are large, complex, and inherently unstable further complicates development of a robust workflow. Because chromatography processes can alter a biologic in ways that could impair its intended therapeutic function, investment in process development is critical. Techniques such as design of experiments (DoE) can be used to identify the best approach during process…

eBook: mRNA — Revisiting a Technology That Has Rocketed into Success
At the end of 2018, BPI published its first eBook about mRNA drug products — and quite a lot has happened since then! Our initial report highlighted companies working on mRNA therapeutics for cystic fibrosis, heart disease, and cancer, as well as vaccines. The latter approach took off in 2020 with the advent of SARS-CoV-2 and the COVID-19 pandemic, and in a stunningly short time, the biopharmaceutical industry has learned much about manufacture, formulation, product design, and distribution of mRNA…
Preparing for Process Improvements: Discussions of the Cell Therapy Industry’s Supply Chain, Automation, and Control Needs
As editors, we are fortunate to have the opportunity to listen to biopharmaceutical developers and innovators discuss the intricacies of their work. Typically, we find that the best discussions come from asking two fundamental questions: What need did you observe in the industry that drove your work, and what technologies would help you do your job better? Over the past five years or so, the answers have shifted. Cell and gene therapy (CGT) innovators are focusing on increasingly complex diseases…
Untapped Potential of Tissue Engineering: The Three Obstacles Holding It Back
Regenerative medicine is the interdisciplinary field comprising tissue engineering, cell therapy, and gene therapy. These biopharmaceutical modalities, also referred to as advanced therapies, are growing rapidly, characterized by groundbreaking therapeutic advances that have the potential to change how healthcare providers deliver care. As Figure 1 shows, cell and gene therapies have gained traction over the past decade, as evidenced by large increases in investment and the number of marketed products. By contrast, tissue engineering investment and product commercialization has lagged…
The Difficulties of Manufacturing Cell and Gene Therapies At Scale
From large-scale manufacturing of one-size-fits-all blockbusters to small-scale processing of personalized therapies, the biopharmaceutical industry has undergone a revolution over the past decade. Among the standout milestones is the development of advanced therapy medicinal products (ATMPs). More than 1,000 of these research-intensive therapies are progressing through clinical trials toward potential commercial manufacturing. Cell and gene therapies (autologous and allogeneic) are targeted for many incurable diseases and conditions, including autoimmune disorders and cancers. Despite the excitement about ATMP potential, developers and…
Manufacture and Regulation of Cell, Gene, and Tissue Therapies: Part 2 — Regulatory Guidances
The US Food and Drug Administration (FDA), the European Medicines Agency (EMA), the Medicines and Healthcare Products Regulatory Agency (MHRA), and Japan’s Pharmaceutical and Medical Devices Agency (PMDA) all offer support and guidance for developers of advanced therapy medicinal products (ATMPs). Some agencies have issued guidelines to help companies through different stages of product development — from research and development to marketing authorization and postauthorization activities. Such guidelines are updated regularly as more knowledge becomes available from the development and…
April 2021: From the Editor
I write this the day after US President Joe Biden’s address reporting his administration’s progress on COVID-19. Vaccines and their distribution and delivery are priorities, of course, and the companies working on them over the past year deservedly have received a great deal of attention. But our pandemic response rests on three other important pillars as well: prevention of exposure through masking and social distancing (as the President reminded us), testing and tracing with diagnostics and data, and treatment of…
Trade-Secret Vulnerabilities: Recent Hacking Schemes Highlight the Need to Protect Proprietary Pharmaceutical Information
On 21 July 2020, the US Attorney’s Office in Spokane, WA, unveiled a sweeping indictment accusing a pair of Chinese hackers of conspiring to steal trade secrets from a number of American pharmaceutical companies and research institutions, including biotechnology companies working on potential COVID-19 vaccines (1). Although the hackers apparently did not succeed in their attempt to obtain vaccine data, their years-long conspiracy involved other attacks on the pharmaceutical industry — and netted them troves of sensitive commercial information. Among…
Biomanufacturing Workforce Development: Fostering Talent During and After the Pandemic
Beyond the human suffering and economic damage caused by COVID-19, one of the most powerful results of the pandemic has been to focus global attention on drug and vaccine development for infectious diseases. Massive investments by governments, institutions, and biopharmaceutical companies have accelerated development of novel therapeutics, including messenger RNA (mRNA) and viral-vector vaccines, that are poised to become transformational platform technologies for biopharmaceutical manufacturing (1). Furthermore, the well-established technology of monoclonal antibodies (MAbs) has lived up to its promise…
Emerging Strategies for Drug-Product Comparability and Process Validation: Part 2 — Validation, Legacy Products, and Lifecycle Management
This two-day CASSS CMC Strategy Forum explored many technical, practical, and regulatory facets of biological drug-product (DP) analytics, process validation, and comparability. Part 1 of this report summarized the discussions on drug-product analytics and comparability in BPI’s March 2021 issue (1). Here we report on day two presentations and discussions on validation, legacy products, and lifecycle management. Session Three: Drug-Product Validation The morning session focused on principles of process validation with examples of challenges specific to drug products. New Risk-Based…
