With the increasing adoption of single-use systems (SUS) in critical stages of biopharmaceutical manufacturing, any lack of system integrity can significantly affect drug product quality and patient safety, as well as incur additional costs due to product loss and disrupted production cycle. This article from Sartorius Stedim Biotech, describes how determining the correlation between liquid leakage and microbial ingress can be used to define MALLs (Maximum Allowable Leakage Limits) of SUS for different process steps. The article also details the…

A Harmonized Approach to Data Integrity
Data integrity is achievable when data collection is complete, consistent, and accurate (1). Failure to maintain data integrity compromises a company’s ability to demonstrate the safety and efficacy of its products. Escalation of serious regulatory actions related to data integrity violations has prompted the need to assess data integrity compliance and implement systems designed to guarantee it. Comprehensive measures must be taken to ensure that data are attributable, legible, contemporaneous, original, and accurate (ALCOA) (2). Preventive measures need to be…
Opportunities for Modern Robotics in Biologics Manufacturing
It should come as no surprise to anyone familiar with biomanufacturing that current designs of bioprocess facilities as well as associated manufacturing spaces and support operations require excessive amounts of manual labor and manual interventions that lead to high labor costs and, consequently, total cost to supply. From receipt of raw materials to process execution and performance review, resolution of quality issues, and product shipping, no industry devotes a greater percentage of operating costs (or cost of goods sold, CoGS)…
Determining Control Chart Limits for Continued Process Verification with Autocorrelated Data
Control charts are used to assist in process monitoring activities. They use an estimate of central tendency (the overall mean) and variation (the standard deviation). Sample standard deviations (S) tend to underestimate process standard deviations (σ) when they are calculated using limited sample sizes of independent results (1). For this reason, the unbiasing constant c4 is used as a divisor when calculating Shewhart control-chart limits. If data used for control charting are positively autocorrelated, that tends to underestimate σ further…
Antibody Derivatives: Deconstructing MAbs for the Next Wave of Biotherapies
Although they make up the largest and most successful category of biopharmaceuticals so far, monoclonal antibodies (MAbs) suffer from certain disadvantages. Some companies are addressing those limitations by deconstructing MAb molecules to create new emergent therapeutics. These antibody derivatives include: antibody fusions and fragments, bispecifics, trifunctional antibodies, and more. This eBook combines market analysis from consultant David Orchard-Webb with technical discussion from BPI cofounder and senior technical editor Cheryl Scott. It also includes commentary from editorial advisor Michiel Ultee and…
The Role of Single-Use Polymeric Solutions in Enabling Cell and Gene Therapy Production: Part 1: Introduction and Manufacturing Process
by Bio-Process Systems Alliance Cell and Gene Therapy Committee The Bio-Process Systems Alliance (BPSA) was formed in 2005 as an industry-led international industry association dedicated to encouraging and accelerating the adoption of single-use manufacturing technologies used in the production of biopharmaceuticals and vaccines. Corporate members include plastic-equipment suppliers, service providers, and users in the biopharmaceutical industry who share this mission. A key focus of BPSA’s core activities is to educate its members and others through sharing of information and development…
A Perspective on GMPs for Cellular Therapy Commercialization
Cellular therapies can be classified by therapeutic indication, by cell types, and by whether cells are taken from and administered to the same individual (autologous) or derived from healthy donors (allogeneic). Regulatory classification of cellular therapies differentiates among minimally manipulated cells for homologous use, transplants or transfusions, and cells that are more than minimally manipulated and regulated as medicines. Medical cellular therapies must meet quality, safety, and efficacy standards to obtain marketing authorization (1–8). Such therapies can be subdivided into…
Scientific and Technological Advancements in Applications of Single-Use Technology: A Conference Report
Single-use technology (SUT) has been used increasingly both in clinical and commercial biomanufacturing (1). Proven major advantages include relatively low capital investment, elimination of batch-to-batch cross contamination and reuse cleaning validation efforts, flexibility in manufacturing, and shortened product lifecycles. However, some challenges and barriers to implementation remain: Consumables costs are increasing. Specific regulatory guidance is lacking, as is component interchangeability and standardization. And few if any leak-proof components/systems are available. International groups and associations focused on setting best practices and…
Cell and Gene Therapy Data Management: Solutions to Address Complex Challenges
At the Phacilitate Leaders World and World Stem Cell Summit 2019, held 22–25 January, Steve Goodman (head of drug product manufacturing at bluebird bio) and Robert Di Scipio (CEO of Skyland Analytics) shared the podium to address what the product and process data-management ecosystem looks like for cell and gene therapy (CGT) development and manufacturing. A starting point for their presentation was that CGT development presents significant data challenges: capturing and analyzing product development and manufacturing data, tracking the collection,…
Is the QbD Toolbox Ready for Cell and Gene Therapies? Integrating Patient Outcomes into Manufacturing Cell and Gene Therapy Bioproducts
In their lifecycle development and manufacturing models, biotechnology products and the biopharmaceutical industry have been founded on principles originating from the pharmaceutical small-molecule industry. Such principles define clinical programs that establish risk benefits of a dosage and its delivery system on healthy individuals and patients. A company then develops a process to manufacture that product consistently over several years. Product quality attributes set through manufacturing controls are expected to ensure patient outcomes in terms of safety and efficacy and deliver…
