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…

April From the Editor

Our focus on regenerative medicine this month, with its inherent personalized approach, brings to my mind aspects of “the patient experience.” Last week at BPI West in Santa Clara, CA, I was intensely moved by the performance of lymphoma survivor Toby Peach (www.tobypeach.co.uk). Our KNect365 colleagues will be asking him back this fall for the BPI Conference in Boston, and I encourage you not to miss him if you’re there. Many of us will be touched by some form of…

Cost of Goods Is Crucial for the Future of Regenerative Medicine: CAR-T Cell Therapy Provides a Case Study in Perspective

In the history of regenerative medicine, 2017 was a critical year. With approvals for Kymriah (tisagenlecleucel) from Novartis AG, Yescarta (axicabtagene ciloleucel) from Kite Pharma (a Gilead company), and Luxturna (voretigene neparvovec-rzyl) from Spark Therapeutics, cell and gene therapies finally made their mark on the regulatory landscape. Then in 2018, those products began both treating patients and bringing in revenues for their sponsor companies. “Patients are being treated, and biotechnology and pharmaceutical companies are being paid for treating them,” said…

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…

Innovation Leadership in Drug Development

A “sea change” in the biotechnology and pharmaceutical industries is leading established players to recruit a new type of drug-development leader. Disruptive innovators such as LG Chem Life Sciences, Google, and Nestlé are challenging established life-science companies to be nimbler, more creative, and more adept at applying new and emerging technologies. To spur creativity and entrepreneurship in research and development, smaller companies and Big Pharma corporations alike are recruiting leaders from different fields both inside and outside the life sciences.…

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…
