Lonza Authors Recent Publication on Availability of cGMP-Manufactured Human Induced Pluripotent Stem Cells for Pre-Clinical and Clinical Applications

Lonza, a global leader in the field of cell therapy development and manufacturing, announced today the publication of an article about the recent completion of the production of clinical-grade induced Pluripotent Stem Cells (iPSCs). The success was reported in a peer-reviewed article titled “cGMP-Manufactured Human Induced Pluripotent Stem Cells Are Available for Pre-clinical and Clinical Applications” in the scientific journal Stem Cell Reports. The article can be found in Lonza’s Knowledge Center: www.lonza.com/ipscarticle The discovery of iPSCs and the availability…

Sartorius Stedim Biotech Launches Flexsafe® 3D Pre-Designed Solutions for Storage and Shipping Applications

Today, single-use bags are increasingly used in all process steps of biopharmaceutical manufacturing. Their robustness, performance and quality consistency are crucial for ensuring the safety and economy of bioprocesses. This is why Sartorius Stedim Biotech (SSB), an international leading supplier for the biopharmaceutical industry, developed a new polyethylene film and the Flexsafe® family of bags that provide outstanding quality and significantly facilitate implementation of next-generation single-use factories. The complete control of the resins, film, bags and their final assembly, as…

Niche Disease: Legionnaires’ Disease by Cheryl Scott Gram-negative, aerobic Legionella pneumophila bacteria were first identified as the cause of an outbreak of severe pneumonia at an American Legion Convention in a Philadelphia convention center in 1976. Since then (and probably long before), it has been responsible for occasional such outbreaks around the world. For example, an epidemic of the disease probably occurred in Minnesota in 1957. Such incidents are usually associated with poorly maintained artificial water systems (e.g., cooling towers…

Effective Management of Contract Organizations: Keeping the Product Pipeline Moving, Compliant, and Available

Both small and large biopharmaceutical companies are increasingly pursuing the outsourcing of manufacturing and testing throughout the product lifecycle. The growing use of contract manufacturing organizations (CMOs) and contract testing organizations (CTOs) has led to increasing complexity within the biopharmaceutical industry as more third-party sites are leveraged to support global markets. To address those issues, a CASSS Chemistry, Manufacturing, and Controls (CMC) Strategy Forum was held in Washington, DC, 27–28 July 2014. The title was “Effective Management of Contract Organizations: Sponsors, Contract Organizations, Health Authorities and Patients — Keeping the Product Pipeline Moving, Compliant, and Available.” The CMC Strategy Forum is…

Management, Notification, and Documentation of Single-Use Systems Change Orders: Challenges and Opportunities

Single-use systems (SUS) consist of numerous plastic components derived from different suppliers. As such, they are prone to changes, including alterations in construction materials or modifications in manufacturing processes. Such changes may originate at the immediate supplier or farther back in the supply chain as a result of product improvements, process improvements, part discontinuation, or even business decisions such as manufacturing site relocation. Whether those changes are major or minor, managing their impact on biopharmaceutial processes and product quality often…

Special Report: Turning Discoveries into Products — Developability Assessments and Highly Efficient Process Design

High costs and long timelines for biopharmaceutical development are cause for reflecting on how best to allocate resources from the earliest discovery stage through critical go–no-go junctures. With inputs ranging from science, engineering, and economics, the coined term developability becomes the synthesis of answers to such questions as How well does the target represent a disease state? Does manipulating that state bring about improvement? Does the molecule behave as expected in living systems? What can be done about the emergence of independent safety, toxicology, and/or immunogenicity warning signs? Can the molecule…

The Secret Life of Protein A

Affinity chromatography with protein A has become the foundation for purification of nearly every therapeutic IgG in commercial production. One of the features most responsible for its success has been its compelling simplicity. IgG binds. Contaminants do not. Load, wash, and elute pure IgG. In the real world, however, protein A does not elute pure IgG. It typically contains several hundred to a few thousand parts per million (ppm) contamination by host-cell proteins (HCPs) and other contaminants. Numerous studies demonstrate…

Identification and Quantification of Heat-Shock Protein 70: A Major Host-Cell Protein Contaminant from HEK Host Cells

Recombinant therapeutic proteins are commonly produced by cell lines such as Chinese hamster ovary (CHO), human embryonic kidney (HEK) 293, murine myeloma (NS0), and Escherichia coli bacterial cells. Host-cell proteins (HCPs) are indigenous proteins produced by those expression hosts and considered to be process-related impurities generated from the cell culture process (1). HCPs are potentially harmful and immunogenic to patients, and they can compromise the stability of protein drugs (2–4). For those reasons, HCPs must be consistently removed or reduced…

Comparison of Concentration Measurement Technologies in Bioprocess Solutions

Biopharmaceutical manufacturing involves complex process steps. Exacting production conditions are typically required to maximize the yield, purity, and quality of biological products. In recent years, process analytical technology (PAT) has been increasingly used to monitor key process and performance parameters in real time. That has enabled better control of production conditions. An important parameter required to achieve consistent results in many bioprocessing steps is solute concentration in process fluids. The Critical Need for Concentration Measurement Many biopharmaceutical manufacturing process steps require measuring…

Compatibility Assessment of a Model Monoclonal Antibody Formulation in Glass and Blow–Fill–Seal Plastic Vials

Blow–fill–seal (BFS) technology has been recognized by the industry as an advanced aseptic solution (1–3). Catalent Pharma Solutions has been commercially supplying sterile BFS products to the pharmaceutical industry for decades, primarily in the respiratory and topical ophthalmic markets. Such product formulations range from simple solutions to emulsions with drug substances from classical small molecules to large complex proteins such as biologics. The company also has optimized BFS processes and its Advasept plastic container system for the manufacture of sterile…
