The impact of human biological samples (HBS) across the end-to-end research and development process is huge. Having access to the right sample at the right time can unlock new science to enable the development of new treatments for patients. To secure rapid access to samples, AstraZeneca’s biobanks are closely situated at its global research sites. Samples come not only from AstraZeneca (AZ) sponsored clinical trials, but also from academic collaborations or sourced from approved vendors.

The AZ biobanks currently hold four million samples globally, to support ongoing and future science. Our ‘One Biobank’ strategy includes a single sample catalogue where all samples are visible to our scientists as well as the governance oversight of all sample use globally. The biobanks are part of the Biosamples function which provides expertise across the HBS lifecycle, covering sampling needs and logistics on every clinical program within AZ, the registration and storage of samples in the biobanks, and the compliance and governance to make sure that every human sample is treated in the right way.

The sample catalogue in AZ also includes primary cells and cell lines classified as HBS, depending on local legislation. We have defined processes to provide biobank and governance oversight of these cells, but rely on the AZ cell banks to provide the storage conditions and additional oversight required for the cells.

Karin Gedda has during her many years in AstraZeneca (AZ) been working in all phases of early drug discovery, from identification of targets through lead optimization to successful selection of candidate drugs and submission of drugs for clinical testing. Being a cell biologist/biochemist by training, her focus has been on supporting projects with high-quality screening data using a variety of assays in different formats. Over the last four years she has moved on to leading the sample management teams and now holds the role as Head of AZ Gothenburg Biobank within Precision Medicine and Biosamples. The AZ biobanks hold clinical trial samples as well as samples from academic collaborations and commercially sourced material. Lately, with the formation of the new Biosamples function, Karin’s focus has been on defining AZ biobanks’ strategy moving forward.

Understanding the criticality of raw material attributes to our products and processes allows us to define appropriate specifications and variability, a crucial part of a robust end-to-end control strategy for our products and processes.

The testing and approved release of raw materials for use in GMP manufacturing can be a process that takes weeks to accomplish, requiring companies to keep extensive inventories. To expedite the release of critical raw materials the Biogen RapidID platform was developed and implemented. The Biogen RapidID program describes an integrated IT and laboratory analytical instrumentation system, allowing incoming materials to be received, tested, and released in just a few hours. Two technologies make up the RapidID analytical platform: Raman and x-ray fluorescence to positively identify over 75 raw materials. To ensure compliance with the relevant agencies, a robust method validation and transfer strategy was implemented for the methods for both respective analytical instruments. The RapidID platform has been successfully implemented at Biogen since 2019.

This presentation will focus on the regulatory guidelines around transmissible spongiform encephalopathy (TSE) risk and how TSE clearance studies can be used as a strategy for controlling such risk. European guidelines on investigation of manufacturing processes for plasma-derived medicinal products with regards to variant Creutzfeldt-Jakob disease (vCJD) risk, as well as FDA discussions, provide guidance on how manufacturers can design TSE clearance studies to ensure the highest probability of regulatory acceptance. The presentation will focus on the advantages and disadvantages of each system for controlling TSE risk, and how these impact the interpretation of TSE clearance studies. In addition, options for steps that manufacturers should consider including and that could provide effective clearance of TSE agents will be presented.

As distributors of human pluripotent stem cells (hPSCs) working to serve the greater scientific community, quality is everything. Poor quality cells can impact reproducibility, jeopardize results, waste time, and drain resources. While consensus guidance for the characterization of hPSCs was established by the International Stem Cell Banking Initiative more than ten years ago, many research groups use them inconsistently, or have failed to adopt them altogether. In screening materials submitted to the WiCell Stem Cell Bank for distribution, we have identified a substantial and concerning variability in cell quality, highlighting the need for improved testing strategies and standards.

As of this abstract, more than 1800 cell lines have been submitted to WiCell for banking and characterization by 31 providing laboratories. The vast majority of these cell lines were generated through grant-funded projects as a resource for the larger scientific community, and reportedly screened prior to submission. Various testing strategies were used by the submitting laboratories, and available characterization information was provided to WiCell for reference. To date, over 800 of these lines have been independently tested by WiCell for thaw viability, genetic stability (karyotype), identity via short tandem repeat (STR) analysis, sterility (bacteria and fungus), and mycoplasma. Of the hPSC lines examined, more than one-third of WiCell-screened cell lines failed this routine quality testing. While there were failures across all tests, the majority of cell lines failed due to unexpected abnormal karyotype.

WiCell has performed a retrospective analysis on karyotype data collected over the course of a decade or service to the larger stem cell community (including more than 15,000 hPSC cultures, both internal and external). This analysis enabled us to identify striking shifts in relative frequencies of recurrent abnormalities. Additionally, through recent collaborative work we have been able to identify previously unknown recurrent abnormalities that may significantly impact reproducibility in banking.

These results show that current ad hoc screening strategies are variable and largely insufficient. Based on this data, we can assume that a substantial percentage of materials used in investigator laboratories have unidentified quality issues that will impact research. This underscores the need for routine testing prior to initiating and following studies. Furthermore, it highlights the need for, and value of, centralized repositories with established quality standards that ensure distribution materials are routinely and appropriately screened.

Her primary focus remains collaborating within these groups to refine consensus standards for banking, characterization, and distribution of research and cGMP grade materials, and working with investigators to support the advancement of stem cell technologies through clinical trial.

Although often operating in the background, biobanking plays a critical role in the diagnosis and development of treatments for a variety of diseases. However, as we witness the urgent international efforts to develop vaccines and other therapies for the current COVID-19 pandemic, patient sample collection, processing, and analyses are at the forefront of this emergency. Biospecimen issues have long been important factors in handling the response to emerging infectious diseases. The US CDC has maintained a biobank for decades, and has found through analysis of its samples that infectious agents responsible for outbreaks such as the hantavirus and Legionnaires' disease were present years prior to the epidemic. Tissue samples from the 1918 Spanish influenza pandemic were used to determine that the origin of the virus was related to strains that commonly infected pigs and humans, and was not of avian origin as had been previously thought. Studies of the 1918 pandemic and subsequent influenza outbreaks have been instrumental in vaccine research as well. The Ebola outbreak in Africa in 2014–2016 presented some unique challenges, due to the high infectivity of patient blood samples. There were also security concerns, i.e. that Ebola patient samples could be used for bioterrorism purposes.

COVID-19 presents some unique issues in the biobanking world. The vast scope of the pandemic, with over 11 million patients globally as of early July, means that laboratories and biobanks are handling many samples involved in developing diagnostics and vaccines. The US CDC has published guidelines for handling COVID-19 samples. Some biobanks have developed their own guidelines, usually based on those of the CDC. Generally, these guidelines mandate the use of biosafety level 2 (BSL-2) rules for laboratories, including the use of protective equipment, use of class II biological safety cabinets, proper disinfection routines, etc. Also, a new US NIH COVID-19 Scientific Interest Group (SIG) has also been organized, where interested parties can join in an online discussion and exchange information about research and resources. At this time, we can expect that this pandemic will continue to be our most critical international concern for months to come, from a public health perspective, as well as from the resulting economic impact. As the number of cases continues to mount, as well as the unfortunate loss of life, biobanks will continue to work in the background to handle their roles in the response. This presentation will provide an update on biobanking activities during the pandemic.

Human and other mammalian cell lines and xenograft tissues, including patient-derived xenografts (PDXs) and patient-derived organoids (PDOs), are essential tools as pre-clinical biomedical research model systems. They are used to study different aspects of biological processes (infection, enzymes, gene structure, and expression control), behavior of different types of human tissues and cells, diseases such as cancers and infection by microbes (e.g., viruses, bacteria), and effects of drugs on normal and abnormal biological processes.

A major concern in using cell lines and patient tissue samples as preclinical research models is that on average 22.5% (range 0–100%) of these samples are misidentified. This can compromise the validity and reproducibility of the research based on these model systems, waste valuable research funds and effort, and damage the reputations of research groups. This presentation will describe the enormity of the problem with examples from the literature and my own work that show how the scientific literature has been contaminated with inadequately authenticated cell lines. Current and new tools that can address this problem will be described.

Christopher Korch received his PhD at the University of California at Davis in Genetics and studied in France, Norway, Sweden, and the USA. In 2000, his University of Colorado Cancer Center core facility was one of the first to implement techniques for characterizing and authenticating human cell lines. In the last 19 years, he has published together with several groups on the identification and confirmation of the identity of authentic and over 80 imposter cell lines and clinical samples by DNA sequencing and STR genotyping. Some of the more salient findings include work with the following groups:
• Prostate Group showing about 30% of the prostate cell lines were misidentified and not suitable models of prostate cancer.
• Thyroid Group showing about 50% of the thyroid cell lines were misidentified and many were not suitable models of thyroid cancer. These finding shocked the endocrine field and have been seminal in the re-evaluation of earlier research. It initiated major efforts to establish authentic thyroid cell lines.
• Ovarian, Endometrial, and Breast Cancer Groups, which in 2012 published a major study on the identity of endometrial and ovarian cancer cell lines, showing extensive contamination, redundancy, and misidentification among these cell lines, raising questions about the validity of many publications using these cell lines.
• The International Cell Line Authentication (ICLAC) which has established that over 500 cell lines are misidentified, i.e., imposter cell lines.
• The ANSI/ATCC Standards group which is revising the Standard for Cell Line Authentication by STR profiling, which is due out in 2020.

Furthermore, Dr. Korch has been interviewed for a book, the Canadian Broadcasting Corporation, magazine articles including Science and Discover Magazine, and several documentaries (such as https://www.biocompare.com/Reproducibility/Cell-Line-Authentication/) and webinars about this problem.

The biopharmaceutical industry has rapidly grown over the past four decades, and mammalian cells now produce the majority of the top drugs by sales. Common cell lines such as Chinese hamster ovarian cells have been selected, somewhat by accident or convenience, and now we rely upon these cells for producing hopefully large quantities of high quality product. However, the random nature of the selection of our top production clones means that alongside the excellent traits they present, each cell line has limitations that pose challenges to optimal biopharmaceutical production, ranging from inefficient metabolism to clonal variation and secretion of contaminating host cell and viral proteins. Can we take a rational approach to engineer each trait and obtain substantially improved cell lines?

We have taken a rational approach to engineering CHO cells to address each of the aforementioned challenges. Specifically, we sequenced the genome of the Chinese hamster and several leading CHO cell lines to obtain a "parts-list" of the cells. We subsequently mapped out all of the molecular pathways involved in CHO cell growth and protein production. Using novel systems biology and AI algorithms, we have predicted how to engineer these cells to obtain cells with limited secretion of bioproducts such as lactic acid and host cell proteins. We have further developed cell lines with more predictable bioprocess behavior, and that provides well controlled and more homogeneous glycosylation. Thus, by rationally engineering the cells, major challenges in cell line development, bioprocessing, and purification can be addressed.

Dr. Nathan Lewis is an Associate Professor of Pediatrics and Bioengineering at the University of California, San Diego. He received his training in biochemistry at Brigham Young University, bioengineering at UC San Diego, and genome editing at the Wyss Institute at Harvard Medical School, where he focused on omics and big data analysis using systems biology modeling techniques. Currently Dr. Lewis serves as the Co-Director of the Center for CHO Systems Biology at the University of California, San Diego, and heads scientific strategy for the CHO cell program at the Center for Biosustainability at the Technical University of Denmark. In these capacities, Dr. Lewis' lab has led substantial efforts to rationally engineer CHO cells to improve production cell phenotypes, and control the quantity and quality of recombinant protein drugs. These efforts were enabled by their work on sequencing and annotating the genomes of the Chinese hamster and a variety of CHO cell lines. His team has also mapped out the molecular pathways controlling CHO cell growth and protein production, and developed novel systems biology and AI algorithms to diagnose the molecular bases of cell and production traits and control process and product quality. Finally, his team has helped lead the development and deployment of novel genome editing strategies to enable high-throughput screening of genetic modifications and implementation of multiplex editing to obtain enhanced CHO cells. Through these many efforts, his team has developed a powerful toolbox for the rational engineering of mammalian cells for the bioproduction of valuable biotherapeutics.

Raw materials can wreak havoc on processes and facilities in a myriad of ways, seemingly with surprises at every turn. At the Merck Raw Material Center of Excellence, our goal is to achieve deep understanding of each raw material in a fit-for-use context to get ahead of unexpected plot twists. The fit-for-use paradigm applies to both commercial qualification as well as technical risk assessments that facilitate the transition from clinical to commercial. As our fit-for-use raw material knowledge management grows, we are also looking ahead to obtain digital, trend-able data in the form of electronic certificates of analysis (CoAs) from suppliers.

The field of cell and gene therapy (CGT) continues to grow at a fast pace. These unique biologics pose both regulatory and testing challenges. Manufacturing process consistency is mainly controlled by (1) raw material and reagent qualification programs, (2) in-process monitoring, (3) in-process control testing, (4) lot release tests, (5) traceability, and (6) validation of the manufacturing process. The viral vectors used for CGT, as well as the raw materials used to manufacture these advanced therapies, are all subject to testing for characterization and safety to ensure product quality and performance. Testing of viral banks ensures identity, potency, purity, and safety prior to the use of these vectors in and throughout production. Biosafety testing of viral vectors ensures that the drug substance and drug product are free of adventitious agents and impurities before administration to patients. In this talk, we will review some of the challenges and solutions in viral vector testing.

Raw material variability presents a high risk to successful manufacturing of consistent media products. With a recent focus on trace elements (TE) impurities, raw materials are tested and analyzed for their impact on final product performance. Over time, this results in huge data sets and the challenge is to store, manage, and share the information effectively. This presentation shows our approach to trace element testing and our efforts in using modern tools to archive, organize, and successfully utilize this data for different applications. The platform helps us to proactively track historical trends, alert supplier-to-supplier variability, and to create predictive media formulations, all with a goal to reduce lot-to-lot variability. Further, with biomanufacturer collaboration and understanding of desirable TE ranges, collectively, we can minimize and control the raw material risk to better manage impurities and variability.

Bacterial, mycoplasma, or viral contamination in cell culture manufacturing processes is a very low probability event, but one with tremendous impact on the manufacturing process and facility if it occurs. Risk mitigation strategies, including intensive characterization of cell banks and seed material, use of animal origin-free and terminally sterilized media and media components, single use bioreactors, and thoughtful engineering of manufacturing spaces have reduced the risk. Despite all these efforts, there is still a requirement to assess manufacturing cell culture harvests for contamination.

Because the traditional adventitious agent or mycoplasma tests take considerable time, contaminant testing is generally only conducted during cell banking and following production bioreactor harvest. To mitigate risk, real-time, quantitative PCR based assays that allow for rapid, highly sensitive detection of mycoplasma, and specific risk virus, mouse minute virus (MMV) and vesivirus 2117 for CHO cultures, can be applied. Additionally, newer technologies utilizing PCR and next-generation sequencing (NGS) can enable rapid, sensitive, accurate detection and identification of bacterial contaminations. Rapid and reliable assays can enable testing for the presence of these agents at multiple points during the cell culture manufacturing process, allowing for the earliest possible detection of a contamination event and identification of the causative agent. These technologies can be implemented for either routine testing or for investigations when bioreactor parameters deviate from typical operating ranges or control limits. This presentation will review the performance and implementation of these methods and include example results from case studies.

The regenerative medicine field is rapidly advancing, with many pivotal trials underway. As the field moves into large-scale commercial manufacturing, cryopreservation becomes an ever more critical component for ensuring maximum efficacy and long shelf-life during end-to-end production. However, the potency and yield of fragile cell types, such as induced pluripotent stem cells and genetically modified cell-based immunotherapies, are significantly reduced post-cryopreservation due to ice damage and genomic and in vivo toxicity associated with current cryoprotectants (e.g. DMSO). These issues further limit the realization of off-the-shelf advanced regenerative medicine products, such as those being developed in allogeneic cell therapy and tissue engineering.

X-Therma applies convergent biomimetic nanoscience to solve this unmet need in biopreservation, pioneering a novel chemistry that is inspired by natural antifreeze protein, developed with modern drug discovery methods.
