Speaker: Regina Gary
Universitätsklinikum Erlangen, Germany
The quality control of cellular therapeutics is especially challenging as there is often a huge biological diversity in the cellular composition of peripheral blood of different individuals and, additionally, cells of patients might be affected by medication and disease when compared to healthy donors.Crucial specifications for the release of cell products include (i) that the identity of the cells (here CAR transduced CD3+ T cells) must be confirmed, (ii) the microbiological quality must be proven as cell products are intrinsically not amenable to final sterilization, and (iii) the quality of the cells themselves must be good to optimal (e.g. high vitality).The most important tools for the analysis of cell products are flow cytometry and the different kinds of microbiological testing such as microbiological culture, PCR for the absence of mycoplasma, and endotoxin testing.One of the challenges is the short shelf-life of not-cryopreserved, “fresh” cell products, making the release of the product based on preliminary results from microbiological testing a necessity.For flow cytometry, not only the analysis of identity and cell counts plays an important role but also the data management as well as the reliable calculation of the required parameters.Here, we give insights to our experiences during establishment and routine performance of quality control.

Speaker: Thomas Matthes
University of Geneva, Switzerland
Chimeric antigen receptor (CAR) T cells represent a highly promising new approach to treat hematological malignancies such as leukemias and lymphomas. Two CAR T cell therapies, tisagenlecleucel and axicabtagene ciloleucel, have been recently approved by FDA and EMA, and others are currently following. Flow cytometry is a powerful tool for the comprehensive phenotyping of individual CAR T cells at multiple stages of treatment, from product characterization during manufacturing and prior to infusion to longitudinal evaluation and follow-up of the infused CAR T cells in patients. The talk will focus on describing key considerations for the development, optimization, validation, and implementation of flow cytometric methods in clinical trial design and for routine monitoring of CAR T cell therapies.

Speaker: Rossana Bugianesi
Pediatric Hospital Bambino Gesù, Rome, Italy
The production of medicinal products for advanced therapies (ATMP) is a rapidly evolving cutting-edge sector. Due to the drive for innovation that characterizes the ATMP, quality control is often challenged by the needs to fully meet the GMP requirements and is committed in continuous improvement of the analytical tools.At the production site for Gene and Cellular Therapy of the Pediatric Hospital Bambino Gesù we have recently implemented a new CAR T production process by using the automated cell processing platform CliniMACS Prodigy®.The flow cytometer MACSQuant® Analyzer was acquired for this project and was tailored to meet specific product quality control needs. Indeed, this instrument is equipped with an algorithm-based express mode that enables automatic gating to support unbiased data analysis. Additionally, the MACSQuant Analyzer provides an automatic cells absolute count per volume that delivers highly accurate results.A further aspect related to the quality control of the product CAR T concerns the clinical requirement for a fresh product to administer within 24 hours post-production. In order to assess the microbiological safety of the product in time for the infusion the bioMérieux BacT/Alert® 3D system was implemented. The BacT/Alert® provides an automated microbial detection system that allows faster microbiological analysis from 14 days down to a maximum of one week. For this project, the microbiological analysis is performed in advance on an in-process control sample collected one week before the end of process. A risk assessment has shown that this approach is acceptable because the entire manufacturing process is mainly carried out in a closed system. With the aim of definitively guaranteeing the sterility of the product upon infusion, we are developing a qPCR method for the rapid microbiological detection in just 4 hours.

Speaker: Ulf Geumann
Minaris Regenerative Medicine GmbH, Ottobrunn, Germany
Cell-based therapies have started to offer treatment options for previously incurable diseases. A few of them have already reached marketing authorization in various areas reaching from CAR T cells against lymphoma and leukaemia, limbal stem cells for injured eyes to modified human stem cells for severe combined immunodeficiency and infusion-dependent beta thalassemia. Compared with small molecules or antibodies these genetically modified cells pose novel challenges not only regarding their manufacturing but also their analytics. Minor differences in the cellular product can decide between success and failure in the clinic. Flow cytometry offers the opportunity to analyse various parameters in parallel with single-cell resolution for an in-depth characterisation. On certain devices the volumetric, i.e. bead-free, determination of a reliable cell count has become possible, making an additional cell count process unnecessary. Even though it is a very powerful method it is not without pitfalls. Initially focussed on academia, GMP compliance aspects such as data integrity have long been neglected by the manufactures of flow cytometry devices and require particular attention. As one of the pioneers in the European ATMP field, we had to make efforts to integrate flow cytometry in the GMP environment at Minaris Regenerative Medicine GmbH (Minaris EU). In addition, due to the complexity of the device, system performance must be monitored closely to ensure consistency over time. At Minaris EU, this is done in a three-step procedure using calibration beads, Rainbow beads and Miltenyi Biotec’s 8-color immunophenotyping kit thereby spotting even minor changes in system performance and ensuring reproducibility.

Fluorescence microscopic analyses of large biological samples are subject to technical limitations due to their opacity, which causes light absorption, reflection, and scattering. These physical characteristics are particularly challenging for analyses of anatomy and physiology. However, new technology that overcomes these limitations is light sheet fluorescence microscopy, which in combination with optical tissue clearing enables three-dimensional analyses of large tissue samples. By using fluorescently labeled antibodies and obtaining endogenous fluorescence proteins, optical clearing methods together with light sheet fluorescence microscopy enable the specific identification of biological structures down to individual cells.
According to this, we were able to extend standard techniques of clinical diagnostics with new, more specific analyses in the context of kidney diseases. Light sheet fluorescence microscopy can also be used to analyze the therapeutic efficiency of new drugs, in this case in connection with the therapeutic treatment of inflammatory bowel disease (IBD). In addition to these medically focused applications, light sheet fluorescence microscopy also represents a promising technology in basic research. For example, we were able to identify and characterize a previously unexplained blood vessel system in long bones for the first time, which makes an essential contribution to the anatomical and physiological understanding of this organ. We were also able to identify a previously unknown macrophage population in knee joints that forms a physical barrier to the joint and shields it from inflammatory immune cells. This discovery opens up completely new therapeutic approaches for joint-associated diseases such as rheumatoid arthritis or gout. These examples illustrate the wide range of applications of this technology and its high potential for future studies in the field of biology, translational research, and clinical application.
