In a 2006 report, the US Department of Health and Human Services hailed regenerative medicine as “the vanguard of 21st century healthcare” and “the first truly interdisciplinary field that utilizes and brings together nearly every field in science” (1). To fuel support for regulatory, legislative, and reimbursement initiatives in this new therapeutic class, a small group of scientists, life science business executives, patient advocates, and other experts formed the Alliance for Regenerative Medicine (ARM, http://alliancerm.org). Starting with 17 charter members,…

PEGS The Essential Protein Engineering Summit 29 April – 3 May 2013 — Seaport World Trade Center (Boston, MA)
This spring, Cambridge Healthtech Institute (CHI) will host its ninth annual PEGS: The Essential Protein Engineering Summit at the Seaport World Trade Center in Boston, MA. Record attendance is expected in 2013. Its growth and success is attributable to the quality of scientific programming, expanded exhibit hall, and ample networking opportunities. In addition to the new venue on Boston’s waterfront, the 2013 PEGS event now offers six programming streams and 16 conferences in protein and antibody engineering, oncology, expression, analytical,…
Deal-Making in the Biosimilars Market
Driven by significant opportunity and a perceived lower risk strategy for taking a slice of the booming biologics market, companies have been investing heavily in biosimilars to capitalize on a market that’s forecast to be worth US$3.5 billion by 2015. To exploit this opportunity, companies have embarked on a hearty meal of deal-making. Since the biosimilar market’s formal inception in Europe in 2005, deal flow has been solid. Generics companies made early forays, seeking to leverage relationships with payers and…
Implementation of Quality By Design in Vaccine Development
At the IBC Third Annual International Forum on Vaccine Production, I presented an outline of “Best Practices for Quality by Design (QbD) in Biological Products and How to Implement in Vaccines.” It covered process development and QbD principles, best practices used in biologics, how QbD fits in with process validation, how it applies to vaccines, and some thoughts on the potential for seasonal vaccines. Shifts in Process Development Classic process development (as practiced in the early days) generally involved rudimentary…
Manufacturing Culture
Life sciences company leaders need to put the right people, processes, and technologies in place to create evolutionary cultures. Such cultures would embrace advanced manufacturing process intelligence and reap related business benefits. Since the late 1990s, my software company has helped biomanufacturers improve their process understanding. In that time, we’ve seen regulatory drivers such as quality by design (QbD) and process analytical technology (PAT) guidances call for improved manufacturing process performance through better process understanding and optimization. We define process…
Antibodies, Bioassays, and Cells
It’s no surprise that immunochemistry forms a broad and solid basis of biopharmaceutical analytical laboratory work. Immunochemicals include antibiotics and antigens, nucleic acids and nucleotides, enzymes, lipids, antioxidants, probes and dyes, and proteins and peptides. Available from companies such as Advanced Immunochemical, Immundiagnostik, Lampire Biological Laboratories, and Rockland Antibodies and Assays, their many uses include antibody isotyping and fragmentation. Adjuvants, buffers, assay kits, target biomolecules, and phage-display systems support those applications. Because background and off-target effects complicate the study of…
Performance of a Salt-Tolerant Membrane Adsorber in Flow-Through Mode
Monoclonal antibodies (MAbs) have become the most prevalent therapeutics in the biopharmaceutical industry. Their downstream purification typically involves protein A chromatography as a capture step followed by one or two additional chromatographic polishing steps. Additional unit operations dedicated specifically for viral clearance (e.g., viral inactivation and filtration) are added to ensure product safety. According to a survey of Amgen processes, after processing through a protein A column, only trace amounts of impurities such as Chinese hamster ovary cell protein (CHOP)…
Protein Scaffolds
The recent success of monoclonal antibodies (MAbs) as therapeutic agents to treat cancer, multiple sclerosis, rheumatoid arthritis, and other chronic inflammatory and autoimmune disorders (Table 1) has catapulted these once difficult-to-develop molecules to the forefront of modern molecular medicine (1, 2). The size of the global MAb market in 2008 was valued at almost US$28 billion. Industry analysts predict that the size of the MAb market will grow to almost $68 billion by 2015, with the largest growth occurring in…
Evaluation of a New Single-Use UV Sensor for Protein A Capture
As the adoption of single-use systems continues to expand beyond bags and tubing to complete process steps, a full range of sensing technologies will be needed to complement the resulting varied single-use applications. Single-use sensors must meet or exceed the performance of traditional sensing technologies in areas such as accuracy, response time, ease of use, control system integration, process compatibility, regulatory requirements, and cost. Single-use flow-through process sensors are currently available for pressure, temperature, flow, and conductivity. Here, we report…
Preformulation Development of a Recombinant Targeted Secretion Inhibitor
Our company carried out a preformulation study on a recombinant targeted secretion inhibitor (TSI) with contract research organization (CRO) Avacta Analytical. In this protein, the binding domain of botulinum toxin is replaced to broaden the toxin’s therapeutic potential and allow drug development to be targeted towards a specific disease. In our study, we took advantage of the high-throughput, microvolume protein analysis of Avacta’s Optim 1000 fluorescence and light-scattering instrument (which is distributed in the United States by Pall Corporation). It…
