Development of a Novel Cell-Separation Platform: Discussion with Quad Technologies CEO Sean Kevlahan

Releasing and separating cells from surfaces and capture molecules are critical steps in cell therapy development. Research into such therapies as chimeric antigen receptor T cells (CAR-T) cancer therapies and stem-cell regenerative medicines demand the isolation and purification of viable and functional target cells. A number of cell-separation strategies can be used to produce such cells, but they are not able to deliver the required efficiency or scalability and can also cause damage to cells or affect their phenotype. Since…

Therapeutic Gene Editing: Tools to Facilitate Basic Science or Stimuli for a Paradigm Shift in Biomanufacturing?

Historically, fundamental science and process engineering were separated by distinct vernaculars and a decade or more in the translation pathway of candidate therapeutics from laboratory to bedside (1). This crude metric holds true for the origins of the modern pharmaceutical industry, namely fine chemicals that supported the high-margin small molecules that constitute the majority of the pharmacopoeia even today. But as illustrated by deeply interwoven careers, companies, and technologies — including those related to monoclonal antibodies (MAbs) — that classic…

Bioprocessing Standards for Single-Use Components Are Moving Forward

With the escalating use of single-use technology in bioprocessing, suppliers have had to rapidly develop disposable components such as fittings, tubing, pumps, sensors, and flexible containers for bioprocessing. Single-use technology is growing so fast that the organizations tasked with guiding its growth are having difficulty keeping up. Contributing to this problem are factors such as company needs, regulatory requirements, market pressures, and costs. That growth has posed considerable concerns for the bioprocessing industry about the presence of organic and inorganic…

Rapid Formulation Development for Monoclonal Antibodies

Monoclonal antibodies (MAbs) are at the focal point of biologics development. Many of the best-selling drugs are therapeutic MAbs or related proteins (1–2). The combined world-wide sales from MAbs will be nearly US$125 billion by 2020 (3). About 50 MAb products treating a range of diseases have been approved in the United States or Europe. With the large number of MAbs progressing through discovery, biomanufacturers need to accelerate process development and move projects rapidly into clinical manufacturing (4–5). Formulation development,…

Addressing Variability in Product Labeling: Explore Dynamic Labeling for Your Global Enterprise

Adding to the complexity of drug-product labeling, companies face a broad range of evolving requirements. Those include regional, language, customer, and regulatory requirements that must be met quickly and efficiently to prevent supply-chain disruption. Companies that cannot meet those requirements can end up with fines, dissatisfied customers, and loss of business. Enterprise labeling solutions allow drug makers to deal with variability in labeling by providing label formatting that supports myriad different label combinations with a minimum number of label designs.…

The Global Emergence of Single Use

Adoption of single-use manufacturing continues to expand globally and is showing no signs of slowing down. And why should it? The biopharmaceutical industry is challenged to produce safe, effective therapies and vaccines amid the constant pressure to lower cost per dose in addressing healthcare needs of not only the western hemisphere, but emerging markets as well. To meet these challenges, manufacturers are turning to single-use and hybrid systems that incorporate a balance of stainless and single-use equipment. Over the past…

A Single-Use Process for Production of Recombinant Human Follicle-Stimulating Hormone

Follicle-stimulating hormone (FSH) is a heterodimeric glycoprotein consisting of noncovalently linked α and β subunits. It stimulates the growth of immature follicles in ovaries and primary spermatocytes in testes and thus plays an important role in human reproduction (1). Human menopausal gonadotropin for infertility treatment was first introduced into clinical practice in 1950 (2, 3). Subsequently, treatments with urinary FSH have been replaced by recombinant human FSH (rh-FSH), which has been shown to provide several advantages such as absence of…

Pressure Rating for Bioprocess Single-Use Assemblies

Single-use systems (SUSs) are engineered process equipment solutions for pharmaceutical and biologics production. They offer several key advantages, such as lowering energy costs to reduce utility requirements, minimizing cleaning validation efforts, reducing water and chemical use, and enabling flexibility in manufacturing. Use of SUSs is increasingly popular in almost all fields of bioprocess applications (1, 2). SUSs most commonly comprise components made of polymeric materials, which together create a system or unit operation designed for one-time or campaign use. Single-use…

How Advanced Single-Use Polymeric Materials Influence Extractables Testing

Implementation of single-use systems in both upstream and downstream applications continues to grow rapidly. Parallel to that growth is the concern about purity levels of polymeric single-use systems because compounds found in disposable materials of construction can leach into process fluids or final drug products. By definition, extractables studies are intended to identify chemical substances that could migrate into process fluids. These tests generally take place under exaggerated conditions that exceed those typically found in bioprocess manufacturing or storage. Industry…

Monitoring Live Biomass in Disposable Bioreactors

Often simply referred to as capacitance, radio-frequency (RF) impedance has been used for over two decades to measure online biomass. It is generally regarded as the most robust and reliable method to monitor live-cell concentrations in mammalian cell culture (1). Many biopharmaceutical companies have now made the transition from conventional glass or stainless steel multiuse (MU) vessels to single-use (SU) bioreactors. Disposables are rapidly becoming the preferred platform for new processes requiring current good manufacturing practice (CGMP) compliance. At the…
