When considering integration of single-use technologies (SUTs or disposables) into a manufacturing process and facility, a number of criteria should be satisfied. These criteria govern both selection and implementation. Each criterion should be established by due diligence in which end-user requirements and the operation setting are considered carefully. Depending on a facility’s infrastructure and even a company’s business model, end users will define their criteria differently. Companies are driven to single-use technologies because of the simplicity and flexibility they impart…

Emerging Analytical Technologies for Biotherapeutics Development
A major goal of pharmaceutical development is to characterize pathways of chemical and physical instability and then to develop strategies to minimize them. Deamidation and oxidation are examples of the former, aggregation a result of the latter. The potential for the presence of multiple variants in protein-based pharmaceuticals highlights a need for analytical methods capable of reliably and accurately identifying and measuring those variants. The ideal analytical method would be sensitive, accurate, linear over a broad range, resistant to sample-matrix…
Reconsidering the Supply Chain
An emerging challenge for biotech companies is understanding the bigger picture: How should manufacturing facilities be configured to link together process technologies? Should plants be highly flexible or focus on process standardization? How would a disruptive new technology affect current supply chains, and how could it be implemented? Meeting the challenge requires a complete and detailed understanding of supply chains. Much current focus in process development is on improving operations, with limited consideration to how improvements affect “big picture” variables.…
Guide to Disposal of Single-Use Bioprocess Systems
Single-use bioprocess systems can provide a range of environmental benefits beyond those of stainless steel systems. Although single-use systems may generate additional solid waste, benefits include reduction in the amount of water, chemicals, and energy required for cleaning and sanitizing as well as avoiding the labor-intensive cleaning processes required with stainless steel systems (1, 2). One of BPSA’s core activities is to educate users and develop guides on issues pertaining to single-use systems. The organization’s disposals subcommittee was chartered to…
Secrets to a Successful Validation Project
Three major elements comprise validation projects in the biopharmaceutical industry: cost, schedule, and quality. If you can work within a budget, complete activities on time, and maintain regulatory-compliant documentation, then you significantly increase your chances for a successful validation project. Here we suggest ways you can improve these essential measurements with the help of a third-party validation team to achieve favorable outcomes. Team Selection The first key is building a validation team. Cohesion is critical for successful project management. All…
In the Therapeutics Zone
Small molecules are still not providing cures for many diseases, and this is why biological therapies continue to be developed. They often offer greater convenience to patients, as well as longer lasting therapies,” says William Prather, MD, senior vice president of corporate development at the Israeli stem cell company, Pluristem. The therapeutics area at this year’s BIO International Convention will play host to many interesting technologies for producing and improving protein therapeutics, vaccines, and stem cells. Protein Therapies Remain Top…
Development of an Antibody Screening Assay for Selection of Production Cell Lines
Biopharmaceuticals such as recombinant monoclonal antibodies (MAbs) account for a significant proportion of all new drugs (1,2,3). Although manufacturing site capacities have expanded and process efficiencies have improved greatly, there is still some concern the current biomanufacturing capacity worldwide might not meet increasing market demands (1, 2).

Sharing Is What It’s All About
Recently in Washington, DC, two conferences were held on the topics of cell and gene therapy. The California Separation Science Society (CASSS, www.casss.org) hosted a Well-Characterized Biological Products (WCBP) Chemicals, Materials, and Controls (CMC) strategy forum on “Current Practices for Assessing the Comparability and Stability of Gene Therapy Products,” while blocks away, Phacilitate hosted the 2008 Cell and Gene Therapy forum. At the WCBP CMC strategy forum, participants heard the US FDA–CBER perspective on the importance of comparability studies for…
Cutting Down Process Time and Costs
Because the biopharmaceutical industry operates as an industry rather than a nonprofit, the bottom line is an important consideration in every aspect of product design. From laboratory automation methods that speed discovery to streamlined manufacturing processes that incorporate the themes of operational excellence, Lean manufacturing, and quality by design, the industry is undeniably focused on minimizing cost and maximizing revenue. At the BioProcess International European Conference and Exhibition, the Scale-Up and Manufacturing track will focus on economic strategy and technology…
In the Facility Design Zone
As companies grow and expand their product offerings, it becomes necessary to consider manufacturing space. The decision to build is not made lightly, because CGMP manufacturing space comes at a steep price. Estimates range from $500 to $1,400 per ft2 to build new biopharmaceutical manufacturing space (1,2,3). As Jean-Francois Denault, Agnes Coquet, and Vincent Dodelet point out in their article in the February issue of BioProcess International, non-GMP biomanufacturing space comes at a much lower cost due to the lack…
