The Solution Molecular Microscope is an innovative technology that enables the observation of protein molecules in solution in true form. This technology doesn’t require any particular limitations (crystallization, freezing, fixation, labeling, and so on…) as other structural analysis methods. It is a valuable technology for scientists in protein structural analysis and for every biopharmaceutical scientist who wants to see the actual shape of protein molecules in solution.
We asked some scientists to try using our new technology. It showed a different structure to that obtained using existing methods and captured a 3D structural image that supported the actual movement of the protein. We could have excellent results because no one has ever seen the actual molecular structure in a living state. Biopharmaceutical developers, who previously relied on guesswork to culture biopharmaceuticals, are now witnessing a paradigm shift. The Solution Molecular Microscope is turning their understanding of molecular structures upside down, providing them with a new, exciting perspective.
I joined Rigaku Corporation in April 2003, after getting a Master’s of Shimane University, Interdisciplinary Faculty of Science and Engineering. I was a software engineer of the X-ray Instrument division until May 2015. I started my new role in the same division as a head of the molecular structure analysis business.
According to the recently published Biopharma Sustainability Review, 62% of the 800 biopharma leaders interviewed stated that Sustainability is a top priority for the next 5 years, however only 17% are confident in their ability to accurately measure Scope 3 carbon emissions.
How do we change this paradigm?
By driving collaboration across the value chain, which starts by the raw material we source until the end of life of the product we sell.
Cytiva is focused and invested in delivering for customers to accelerate decarbonization and achieving eco-design. We do that by heavy focus supplier excellence and data, data, data.

Thibault brings his passion for Sustainability and systemic changes and now leads the Sustainability transformation Strategy effort across Cytiva.
Automation has been implemented in vaccine bioprocess development to screen larger panel of parameters and gain time at each step of production and analysis. For further integration, the Bioprocess and Analytical Sciences departments embarked on a journey to assess a workflow from sample generation to sample analysis. The comprehensive mapping of existing workflows unveiled opportunities for enhancement, particularly on three pivotal steps: sample preparation and aliquoting for analytical testing, analysis, and digital interfaces.
Leveraging on advanced robotics, sample preparation was automated in standardized containers, encompassing distribution, labeling, tube capping/decapping, and other repetitive and low value-added tasks when performed manually. For analytics, fully automated systems were implemented, as illustrated by the 384-ELISA platform coupled with advanced analytical modules and software. The implementation of a Laboratory Information Management System (LIMS) served as the cornerstone for digital data management and transfer, enabling traceability and seamless communication between laboratories, analytical systems, and bioprocess scientists.
Through automation and digitalization, we have not only optimized our workflow but also laid the foundation for future advancements in bioprocess development. Thanks to this automation and digitalization initiative, we increased analytical pace and throughput and generated additional data, thus contributing to generating more data which is necessary to build relevant bioprocess models as well as digital twins.

I joined Sanofi in 2004 for an internship in global clinical immunology to transfer methods from Val de Reuil to Swiftwater site (6months on both site).
In 2005, back in France I obtained my first job in Marcy l’Etoile site as technician in Analytical sciences department in virology unit working on SRID and virus titration methods for several projects.
I graduated in 2014 master’s degree in Genetic and cell biology, infectiology specialty. It was my first experience in bioprocess as I did my master’s degree internship in bioprocess R&D lab in Marcy l’Etoile.
From 2014 to 2023 I’ve worked as associate scientist in the Analytical sciences department working on several projects and methods/equipment:
Camelid derived VHH domains are versatile building blocks for the construction of multispecific antibody architectures. In this talk, I will present examples on how VHHs can be exploited for the activation of immune cell subsets by engineering efficient effector cell engager as well as by constructing cytokine mimetics. However, one obstacle relies in the foreign nature of camelid derived VHHs with respect to biomedical applications. We have recently described a novel library approach for the isolation of fully humanized VHHs following camelid immunization. I will describe this process that is based on engrafting the immunized CDR3 repertoire onto humanized backbone libraries followed by yeast surface display.

Developability assessment is crucial in the pharmaceutical industry to proactively identify and mitigate risks for drug candidates. Without a thorough understanding of these risks, entire biotherapeutic programs could be jeopardized. Standard monoclonal antibody (mAb) centric concepts may not fully encompass the critical parameters required for next-generation biotherapeutics. This presentation will highlight anticipated risks associated with next-generation biotherapeutics, alongside mitigation strategies, illustrated through recent Novartis case studies. Additionally, approaches to manage the escalating resource demands for risk detection will be explored.

Biologics and especially the rapidly evolving field of Cell & Gene Therapy offers new therapeutic options for patients. However, as the development of these promising new therapies expand, there is a significant need for improved production methods and techniques that are reproducible and adhere to Good Manufacturing Practices (GMP) standards. This step is critical to ensure both the efficacy and safety of these therapies in human trials. Particularly, among the principal challenges is the complexity and scalability of the manufacturing processes required for a wide array of products. Each of these processes requires comprehensive evaluations for efficacy and rigorous analytical quality control. Multiple variables can influence the quality and performance of these products.
In response to these challenges, ACROBiosystems has developed a full range of solutions for Biomanufacturing including Critical Reagents and Raw Materials to support Early development, Process development, Quality Control to Large-Scale Manufacturing & Commercialization. In this talk you will also learn about solutions to develop a scalable stem cell expansion and differentiation process for cell therapy CMC and discover how multiplexing can accelerate quality control during manufacturing.

PAT supports automated, multi-instrument, holistic quality assurance; provides timely critical quality predictions; and captures all necessary, regulatory-compliant data and metadata.
Manufacturability is the design and the intensification of a production process to facilitate operations and decrease the overall costs. This is thus an essential step for a biotherapeutics on its way to market. Although the development pace of biologics has remarkably increased in the recent past to reach early clinical development phases, large-scale manufacturability often remains a concern of late program phases.
Through a few examples, we will illustrate why we think manufacturability should drive process development and how this approach allows us to avoid technical hurdles, increase efficiency and robustness while decreasing costs.
Attracted since always by biology and life sciences and developing further interest in technological domains, I naturally oriented my carrier in the Biotechnology industry.

My mission is to work on collaborative projects and to provide a worldwide customer support and scientific expertise to meet their needs, given the multicultural background from which I come.
Cell density is one of the most important, if not the most important KPI in cell culture and fermentation processes. There are many traditional methods to measure cell density, but these are mainly off-line methods. These have many disadvantages, the main ones being the low resolution and the cumbersome integration of the data into existing systems.
Inline measurements with sensors installed in the reactor are now state-of-the-art and are replacing these traditional measurement methods. Various measurement principles can be used, e.g. capacitive measurements for the viable cell density and optical methods for the total cell density. The sensors provide reliable data for these parameters with very high resolution over the entire course of the process.
These sensors are useful in R&D, process development and also in production. However, there are a few important requirements that need to be met. The sensors should be easy to use, very robust and low-maintenance. They must be verifiable, and the generated data stream should be easy to integrate into existing systems. And, of course, the sensors should be usable under GMP conditions.
Whether and how the Arc sensors from Hamilton AG fulfill these requirements is the subject of this short presentation – you are cordially invited to attend.
Jochen Uhlenküken has been involved in the measurement of cell densities for many years.
As Head of Product Management at Innovatis AG, he was responsible for the development of the CEDEX HiRes® system. This automatic cell counter was revolutionary as it replaced the established manual methods. However, it also provided only a few off-line values during a process.
The emerging methods of in-line measurement with the Hamilton ARC sensors for viable and total cell density then seemed to make more sense to him. He has now been working as an application specialist at Hamilton AG for more than 10 years, supporting customer projects in Europe and Asia in the areas of R&D and production

Major improvements to IC-BEVS remain limited by poor understanding of the underlying biological mechanisms driving host cell response to baculovirus infection and efficient expression of recombinant genes. Here, single-cell RNA-sequencing (scRNA-seq) of baculovirus-infected insect (Sf9 and High Five) cells producing AAV (as gene therapy vector) or influenza VLPs (as vaccine candidate) was implemented for the first time to shed some light into these mechanisms, providing key information for rational design of genetic engineering strategies to improve product titers and/or quality.
Using scRNA-seq an increase in cell heterogeneity as infection progresses was shown in both insect cell lines, as cells shifted towards clusters with higher expression of viral genes. Additionally, infected cells revealed varying transgene levels, highlighting limitations in recombinant gene expression using viral expression systems. Gene expression changes throughout infection and between different cell states were revealed using trajectory- and cluster-based approaches. Identified genes were associated to biological processes such as cell cycle and metabolic pathways, showing great promise to identify targets for assisting genetic and metabolic engineering in insect cells.
The improved understanding of biological mechanisms in various insect cell-based biopharmaceutical production processes holds great potential for advancing this field and promoting the use of transcriptomics in IC-BEVS.

Macrophages fulfill critical functions in immune and tissue homeostasis and are key players in immune health. Their sensory functions, tissue cleaning and effective communication within tissue environment via the release of a plethora of molecules coordinate the control of inflammation, stem cell recruitment and tissue regeneration, collectively driving resolution of inflammation. Impaired resolution of inflammation, is an emerging hallmark in chronic inflammatory immune and degenerative diseases, representing an attractive target for new disease modifying therapies.
We and others have discovered that secretomes have therapeutic activities exceeding that of cells, which led us to develop two clinical ready approaches, harnessing resolution associated macrophages secretomes. Our GMP-certified platform Cell●Secret●Service has been successfully tested transforming resolution associated secretome drugs from of human blood leucocytes.
Our first platform candidate derived from pooled healthy blood monocyte-derived resolution-type macrophages, RESOLVIX®, has demonstrated disease modifying activity in established preclinical sclerosing models in a dose dependent manner. Single intra-venous injections demonstrated immediate and durable control of inflammatory effectors, reengagement of resolution as attested by regaining of macrophages phagocytic activities and most importantly the reversal of established skin fibrosis. Fibrolytic activities were confirmed on patient’s fibroblast samples, further supporting a clinical evaluation in patients with diffuse cutaneous Systemic Sclerosis (dcSSc).
Recently we also confirmed that therapeutically active secretomes, can be obtained from patients own cells. In animals with established collagen-induced arthritis, receiving clinical relevant standard of care treatments, the ex vivo generated resolution associated secretome showed similar therapeutic activity in controlling arthritis, as a secretome from healthy animals. Potency testing on Rheumatoid Arthritis (RA) patients samples confirmed this observation. With our pre-clinical safety data from large animals, established regulatory drug release testing, these new sectreome therapies will be evaluated in clinical proof of concepts of therapy refractory dcSSc and RA, respectively, starting 2025.
If safety and the compelling efficacy is confirmed, our a next generation secretomes might become a new generation of truly disease modifying biological drug candidates.

Today, virus-based products like oncolytic viruses and gene therapies are part of the most promising biotherapies. The development of biomanufacturing processes for viral products is not a straight road. It is generally associated with process complexity and biological variability. In depth expression system characterization by adding biological data to standard chemical data will help to understand bioprocesses. With a close collaboration between Naobios and Gensensor, case study from Vero cell substrate-based process will illustrate how transcriptomic data may help to understand and monitor biological variability linked to bioprocesses.

In the realm of biopharmaceutical production, Chinese Hamster Ovary (CHO) cells have emerged as the main expression system for recombinant therapeutic proteins (RTPs), despite the availability of several alternative cell lines. CHO cells are among the most widely used worldwide for their unique advantages, e.g, the variety of post-translational modifications that closely mimic those found on human cells (Stach et al. 2019); their high degree of biosafety due to their low risk of propagation of human viruses infection (Lalonde and Durocher, 2017); their adaptability from adherent to suspension cell culture in serum-free media (Davami et al. 2014). Thanks to these combined attributes that solidified the position of CHO cells, they have become the gold-standard of the bioindustry and are responsible for the production of approximately 70% of all marketed RTPs (Pereira et al., 2018; Stolfa et al., 2018; Dziomba et al. 2023).
Fetal bovine serum (FBS) is commonly used as a supplement to basal media for in vitro cell cultures (including mammalian, animal, insect, and bacterial cells). Many studies have revealed its rich composition, containing essential macro- and micronutrients such as growth factors, adherent factors, amino acids, hormones, and vitamins (Michael Butler et al. 2020), which are crucial for proper cell function. In addition to the ethical issue, increasing demand, high cost, significant contamination risks (bacterial and viral), and batch-to-batch variability of FBS prompt us to seek alternatives. To reduce or eliminate FBS use, we have decided to implement culture media with various plant protein hydrolysates. Although serum-free media have been available for several decades, and their widespread adoption has increased, despite the fact that their compositions are undefined for users. Our goal is to make these serum-free media more accessible considering that serum-free media cost about 1.5 to 3 times more than serum-containing media.
Several publications highlighted the effects of vegetable proteins hydrolysate (peptones) as supplements in basal media, i.e : the enhancing of the cell growth and productivity of recombinant proteins (Burteau et al. 2003; Michael J. Betenbaugh et al. 2020). Some publications have shown an enhancing of the volumetric productivity more than 100%, and a 40% increase in cell number (Davami et al. 2014; Davami et al. 2015). Then, the composition of these plant hydrolysates varies according to the plant source and the production process. Thanks to their vegetable origins there are neither ethical issues, nor health standards.
In the present study, the effect of different peptone concentrations on the CHO-K1 cell line under various culture conditions (adherent/suspension) in a basal medium with a 10-fold reduction of FBS have been evaluated. Supplementation with wheat peptones at defined concentrations increased the viable cell density of CHO-K1 in adherent conditions by 190 – 265%.
Additionally, the suspension culture exhibited different results compared to the adherent conditions. In suspension cell culture, only three peptones – wheat, soy, and pea – enhanced viable cell density compared to the medium without hydrolysates. Actually, the only peptone supplementation is not enough to be completely serum-free, but that can reduce the FBS consumption.

Process analytical technology (PAT) aims at real-time, sampling-free monitoring of bioprocesses, for instance at the upstream stage (USP), when suspensions of CHO (chinese hamster ovary) cells grow in bioreactors and produce monoclonal antibodies (mAbs). The advantages of in-line PAT over the off-line approaches are numerous, from scientific, economic and ecological points of view. Using light as a non-invasive PAT tool is one of the promising ideas that give rise to various technological solutions. Nevertheless, the implementation of novel PAT approaches is limited and still requires further progress in analytical instrumentation and its integration in the whole process.
In this talk, we plan to present a short overview of advances in implementation of molecular optical spectroscopy as a PAT tool in upstream processing of therapeutic antibodies we obtained in the framework of our interdisciplinary research project CLIMB’IN. The project uses analytical spectroscopy based on light absorption and/or multi-angle scattering, both elastic (Rayleigh) and inelastic (Raman) for quantitative monitoring of multiple critical process parameters (CPPs). The advances reached by the CLIMB’IN consortium involve instrumental design and experimental protocols, with a particular focus made on machine learning algorithms. Brought together, these advances allow to improve the relevance and the robustness of the corresponding PAT approaches required for their industrial implementation.

The development of biomanufacturing processes for viral products is not a straight road. It is generally associated with process complexity and biological variability. In depth expression system characterization by adding biological data to standard chemical data will help to understand bioprocesses. With a close collaboration between Naobios and Gensensor, case study from Vero cell substrate-based process will illustrate how transcriptomic data may help to understand and monitor biological variability linked to bioprocesses.
