Case Study for a Facility-Fit Driven Process Development

Time to clinic and time to market are the key drivers for client success in the biopharmaceutical industry. Facility fit is becoming key to understanding process constraints and which aspects of the process have the largest impact on enabling facility fit. Process development with facility-fit constraints in mind will ensure a smooth technology transfer and shorten the timeline of current good manufacturing practice (CGMP) product delivery to clients.

Cryopreserved Leukapheresis Materials Help Alleviate Donor Sourcing Issues

Reliable access to high-quality starting material is a primary challenge in cell therapy manufacturing. Freshly isolated leukopak starting materials depend on donor availability and are vulnerable to cell losses from scheduling changes and other unforeseen circumstances. Flexibility often is required for cell therapy manufacturing. Therefore, relying solely on freshly isolated starting material is impractical, particularly when cell therapy logistics involve global shipping and distribution. Donor sourcing is among the most critical factors shaping cell and gene therapy (CGT) supply chains.…

Innovations in the Manufacturing of Cell and Gene Therapies

Advancements in next-generation cell and gene therapies are fulfilling the promise of personalized medicine and attempting to cure and heal patients. Multiple approved products have been launched in global markets and the number of clinical trials continues to grow. Developing innovative advanced therapies is one of the biopharmaceutical industry’s greatest opportunities to dramatically improve patients’ lives. WuXi Advanced Therapies is a contract testing, development, and manufacturing organization (CTDMO) that has launched several innovative world-class platforms. It offers integrated platforms to…

eBook: Drug Delivery —
Partnerships Are Key As Medical and Digital Worlds Converge

Drug delivery is advancing into a digital future. Information technology is changing aspects of every operation in the biopharmaceutical industry. Meanwhile, machine learning and cloud computing are not only finding their way into drug development, manufacturing, and distribution, but also into drug-product delivery devices themselves. As a result, many biopharmaceutical companies are seeking medical device expertise through strategic alliances and contract services. New delivery devices can help big companies extend patent protection on established marketed products, for example, and provide…

Making MAbs: Bioprocess Advancements Challenge Platform Assumptions

Still the largest sector of the industry, monoclonal antibodies (MAbs) have dominated the biopharmaceutical stage for over 30 years. Some observers might think there’s nothing new to say about these molecules; others point to antibody derivatives as a more exciting alternative. But MAbs are far from an outdated technology. From biosimilar developments to cell-free synthesis to yeast display, immunogenicity improvements, and fully human antibodies — as well as improvements in process efficiency and cost reductions, as discussed herein — the…

Tracking Therapeutic Antibody Development in a Pandemic

The COVID-19 pandemic has generated a significant and rapid response from scientists who aim to develop drugs and vaccines in the academic, government, and industrial sectors. Such interventions are essential to containing SARS-CoV-2, the coronavirus that causes the COVID-19 disease. To inform and educate the public about global efforts to develop targeted therapies such as monoclonal antibodies (MAbs), The Antibody Society (TAS) and the Chinese Antibody Society (CAS) have designed and implemented a freely available online database called the COVID-19…

G-Protein–Coupled Receptors: Promising Targets for Antibody–Drug Conjugates

G-protein–coupled receptors (GPCRs) are a large and diverse family of seven-transmembrane–domain proteins expressed on the surface of human cells. These molecules respond to external stimuli by initiating signal-transduction pathways that affect the expression of a large family of genes — which, in turn, regulate a range of vital physiological processes and functions. Figure 1 illustrates the general pathways of GPCRs. Without these proteins, humans simply could not survive: Without β-adrenergic receptors, we could not regulate our blood sugar, for example;…

Next-Generation Biotechnology Product Development, Manufacturing, and Control Strategies, Part 1: Upstream and Downstream Strategies

Future biomanufacturing must address industry drivers, including the need for decreasing cost of goods (CoG), increasing market globalization, shortening development time for pipeline products, reducing risk to patient supply, and improving product quality. A CASSS chemistry, manufacturing, and controls (CMC) forum entitled “Next-Generation Biotechnology Product Development, Manufacturing, and Control Strategies” took place on 16–17 July 2018 in Gaithersburg, MD, to address those opportunities. Advanced technologies include single-use bioreactors, alternating tangential-flow (ATF) systems used during fermentation, modular and closed process equipment,…

Run Rules with Autocorrelated Data for Continued Process Verification

Control charts can be used to assist in monitoring of biopharmaceutical product quality attributes as part of continued process verification activities. A number of tests known as run rules have been developed to assess whether biomanufacturing processes remain in statistical control. In practice, results for such attributes can be positively autocorrelated. Simulated data are used to assess the performance of run rules with autocorrelated data to assist in determining risk–reward profiles for process monitoring. Autocorrelated Data The tendency for data…

Technology to Transform AAV Manufacture

Adenoassociated virus (AAV) vectors are a popular choice for modern gene therapies because of their favorable safety profile, low immunogenicity, and the ease with which they can be transduced into different cell and tissue types. An AAV genome is a single strand of DNA comprising a replication (rep) gene, which encodes regulatory proteins involved in genome replication, and a capsid (cap) gene, which produces three capsid proteins. However, AAVs cannot replicate alone. In nature, AAV shares an exquisite relationship with…
