Improved vector design eases cell line development workflow in the CHOZN GS-/...Merck Life Sciences
This poster was presented at ESACT meeting in 2017 in Lausanne, Switzerland. Cell line development for production of monoclonal antibody therapeutics requires an expression vector encoding both the heavy and light chains of the antibody. When expression of the heavy and lights chains is driven by the same promoter, the sequence redundancy can be problematic for verifying the vector sequence, copy number and insertion site in the host cell genome. This poster describes the work done to identify an expression vector that maintains a high level of antibody expression but lacks the sequence similarities, easing the cell line development workflow.

Quality by Design Principles Applied to Sterilizing Filtration by Michael PayneMerck Life Sciences
Key regulatory documents and regulatory thinking now includes quality by design (QbD). This webinar focuses on how to integrate practical QbD activities into the process and analytical aspects of sterile medicinal product sterilizing filtration and qualification.
In this webinar, you will learn to:
• Focus on practical QbD terms and approaches
• Highlight critical product quality aspects of sterile medicinal products
• Develop design and control spaces for sterilizing filtration
• Easily integrate QbD into the process and analytical operations in early phase development and into manufacturing phase production
Abstract:
Final sterilizing filtration is the last operation in downstream processing to assure the sterility of medicinal products. Poorly defined product attributes process parameters may attract regulatory scrutiny, affect final product sterility and patient safety. A better understanding of QbD concepts and principles allows for better process and analytical monitoring and control at both early and final phase production. The webinar will show how currently available process cGMP information can be practically incorporated into QbD product quality attributes and process parameters. This is especially vital for the third party conducted laboratory work such as bacterial retention and leachable studies.
Use of rapid quality control test methods as alternatives to traditional meth...Merck Life Sciences
Abstract:
As the market for advanced therapy medicinal products (ATMP) matures the complexities of these molecules are evident and challenging when routine standard quality control (QC) testing is applied. Short shelf life from the point of manufacture to administration to the patient results in relatively low volumes for small scale clinical trials or small patient populations. Within a limited time period and with this low product volume, it is necessary to complete required regulatory QC testing, be that for early or late phase clinical trials, or for licensed drug product in a reduced timescale. So, the challenges with QC testing of cell and gene therapies using traditional test methods is time to results, due to short shelf-life, and availability of sufficient sample, due to low production volumes. Over the past years the application of rapid testing of short-life cell and gene therapies that may also help conserve limited product availability have been utilised. Regulatory expectations for using rapid test methods in place of classical or compendial test methods have been defined and this presentation will provide examples and data from our own experience of a range of alternate methods for application to ATMP products.
This is a presentation that I developed and gave to the GMP constituency of a medium-sized biopharmaceutical company to satisfy one of the requirements for ongoing cGMP training. I feel that it very well epitomizes one of my central philosophies surrounding GXP and regulatory topic training -- STORYTELLING.

Accelerate Delivery of High Producing Cell LinesMilliporeSigma
Watch the interactive recording here: https://bit.ly/30FTDG0
The quest for a viable upstream process relies on generation of a cell line expressing the protein of interest. Unfortunately, the search for the best-producing clone is often compared with looking for a needle in a haystack. Making this more challenging is the pressure to get it right the first time, quickly and while mitigating risk and costs.
Although a lot of efforts are made on the clonal selection, there is often few to none optimization done on the expression cassette, including promoter and enhancer selection, or signal peptide. The statistical approach on how many clones should be screened to get to a good producer is often overlooked as well.
We combined a new generation of promoters and enhancers to improve strategies on pool and mini pool screening with both CHO-K1 and our own CHOZN® GS which helped deliver high-producing clones in an accelerated timeline. In addition, we are able to begin process development in parallel with cell line development, further reducing timelines.
In this webinar, you will learn:
* How the strategy approach can help reducing the overall timeline of cell line generation
* How we have expanded our platform by designing a completely new vector/cell/process template
* How we have worked on promoters, enhancers, pool/mini-pool approach as well as on timelines from DNA to clone

Investing in Process Development for Increased MSC Production in Stirred Tank...MilliporeSigma
Interested in developing a robust cell therapy manufacturing platform? In this webinar we will share information in the form of case studies that highlight strategies to optimize your cell therapy production process.
Industry trends in regenerative medicine highlight a critical need for closed cell culture systems that support scalable manufacturing of adherent cell therapies. Typical static in vitro culture methods, however, are often too cumbersome and inefficient to support commercial scale production of mesenchymal stem/stromal cells (MSCs). Single-use stirred tank bioreactor systems are a platform that can address this limitation and have been proven effective for microcarrier-based production of adherent cell therapies. Implementation of optimized process control strategies for parameters such as dissolved oxygen (DO) and agitation rate are key to making an efficient transition from planar culture to stirred tank bioreactors. Herein, a stepwise approach to process development for MSC expansion in a small-scale single-use bioreactor is presented. Case studies focus on strategies to optimize DO control and agitation rates for bone marrow derived MSCs in microcarrier culture, highlighting improvements in process efficiency. In the first case study, the impact different gassing methods have on DO control and whether hypoxic growth conditions affect MSC function are examined. The second case study demonstrates the application of Zwietering’s equation for suspension of solids to overcome scaling challenges often associated with microcarrier culture in stirred tanks. Strategies to further improve the seeding process for bioreactor culture will also be reviewed. Identifying optimal seeding and process control strategies for microcarrier-based bioreactor expansion of adherent cells is paramount for the development of robust cell therapy manufacturing platforms.
In this webinar, you will learn about:

However, the omics (genomics, transciptomics and metabolomics) era, sequencing of the CHO genome and enhancements in genome editing technologies over the past several years have enabled scientists to take a more direct route in cell line optimization through the modification of specific genes that have direct implications on cell culture performance, protein quality attributes and upstream and downstream manufacturing processes. These targets include but are not limited to genes that may be involved in cell cycle regulation, cellular metabolism, cellular transcription and translation, the secretory pathway and protein glycosylation or other post-translational modifications.

Protein viscosity is a major challenge in preparing highly concentrated protein formulations suitable for subcutaneous injection. Recently, the Viscosity Reduction Platform (VRP) was introduced and its technical key features and benefits for formulations were discussed. However, highly viscous solutions do not only pose a challenge when administering a drug to a patient, they can also impose technical limitations in the manufacturing process.
This white paper evaluates the effect of the excipients in the Viscosity Reduction Platform on ultrafiltration processes used to produce a highly concentrated formulation of a monoclonal antibody (mAb). Two filtration methods are demonstrated in this work.

Use of Excipients in Downstream Processing to Improve Protein PurificationMerck Life Sciences
Excipients are used to improve the stability of protein-based therapeutics by protecting the protein against a range of stress conditions such as temperature changes, pH changes, or agitation. Similar stresses are applied to proteins during downstream purification. Shifts in pH during Protein A chromatography, subsequent incubations at low pH for virus inactivation, and changes in conductivity in ion exchange chromatography can lead to aggregation, fragmentation, or other chemical modifications of the therapeutic protein. Given the potential impact on the protein’s structural integrity, there is a need for approaches to reduce the risk presented by the conditions during downstream processing. For example, integration of a solution to prevent aggregation of proteins would be a more efficient strategy than implementing steps to remove multimeric forms.
This white paper highlights the results from a recent paper by Stange et. al., in which protein stabilizing excipients such as polyols, sugars, and polyethylene glycol (PEG4000) were used as buffer system additives. Effect of the excipients on elution patterns, stabilization of the monomer antibody, host-cell protein removal, virus inactivation rates and binding capacity of cation exchange chromatography were explored.
Exploring the protein stabilizing capability of surfactants against agitation...Merck Life Sciences
Agitation of therapeutic protein solutions during manufacturing, shipping and handling is one of the major initiators for protein aggregation and particle formation during the life history of a protein drug. Adsorption of protein molecules to liquid-air interfaces leads to the formation of highly concentrated protein surface films. The rupture of these protein films due to various mechanical processes can then result in the appearance of protein aggregates and particles in the bulk solution phase.
One technique to stabilize proteins against stress induced by liquid-air interfaces is the use of non-ionic surfactants. About 91% of antibody formulations commercially available in 2021 contained a surfactant. Polysorbate 20 and 80, composed of a hydrophilic polyoxyethylene sorbitan and hydrophobic fatty acid esters, made up the largest part being employed in 87% of said formulations.
Despite their frequent use in parenteral drug products, concerns have been raised for decades about the application of polysorbates as surfactants in biopharmaceutical formulations. Autoxidation of polysorbate, caused by residual peroxides in polysorbates, can damage the proteins and can further drive the oxidative degradation of polysorbate. Chemical and enzymatic hydrolysis of polysorbate may lead to the formation of free fatty acid particles, which may become visible; and both mechanisms eventually lead to the reduction in polysorbate concentration. Therefore, the purpose of the current study was to compare various molecules for their capabilities to reduced agitation-induced protein aggregation and particle formation; and furthermore, investigate their underlying protein stabilizing mechanisms.

Characterization of monoclonal antibodies and Antibody drug conjugates by Sur...Merck Life Sciences
Watch the presentation of this webinar: https://bit.ly/3Pjpjvr
Highlights of this webinar:
- Surface plasmon resonance as a powerful tool for biologic characterization including mAbs and ADCs.
- SPR allows rapid binding analysis in real time without using labels for SARS-CoV-2 receptor binding domain mutations.
- Kinetic data is indicative of possible neutralizing activity allowed assessment of neutralizing ability of therapeutic monoclonal antibodies.
- The application can provide preliminarily efficacy information and facilitated mAbs/ACDs candidate selection process
Detailed description:
Characterization of therapeutic monoclonal antibodies (mAbs) or Antibody drug conjugates (ADCs) is challenging due to their ability to bind to a variety of proteins via their Fc and Fab domains, giving rise to diverse biological functions associated with each domain. The Fc domain of mAbs interacts with Fc receptors with varying affinities, which can influence biological processes such as Complement-dependent cytotoxicity (CDC) and Antibody-dependent cellular cytotoxicity (ADCC), transcytosis, phagocytosis, and/or serum half-life.
An important characteristic of an antibody is its Fc effector function. Antibodies can be engineered to obtain desired binding of the Fc region to Fc receptors expressed on effector cells. Hence, it is crucial to evaluate the binding interaction of mAbs/ADC with Fc receptors in the early phase of drug development to understand the potential biological activity of the product in vivo.
Surface Plasmon Resonance (SPR) is a powerful technique to establish binding kinetics in real-time, label free, and high sensitivity with low sample consumption. Along with target antigen binding, it is crucial to evaluate the binding interaction of antibodies and ADCs with Fc receptors. Our SPR case studies investigated the impact on binding kinetics of ADCs with different linkers and the binding interactions of SARS-CoV-2 spike protein variants and evaluated the neutralizing ability of therapeutic mAbs. SPR characterisation can be facilitated in all stages of the product life cycle to ensure the quality and safety of mAbs and ADCs.

Improve Operational Efficiency by Over 30% with Product, Process, & Systems A...Merck Life Sciences
Watch the presentation of this webinar here: https://bit.ly/3adaxWh
When implementing new automation systems, organizations must consider things like deployment time, user adoption, and costs.
They must also consider the cost of doing nothing – that is, what competitive advantage is lost in standing still? What time and quality is lost in repetitive, manual tasks rather than an automated, digital workflow? What operational efficiencies are lost?
In this webinar we examine how a product, process, and system agnostic automation platform can be deployed faster than traditional system specific software while bringing greater operational efficiencies (in many cases over 30% improvement).
To remain competitive in the market, biopharma manufacturers must adopt automation and digital technologies, but most plants still have island of automation consisting of independently functioning, standalone unit operations. This results in operational inefficiency, regulatory concerns, and a poor understanding of the process and product life cycle.
Taking the first, right step must include considering risks, costs, timelines, and technology alternatives. Traditional automation approaches tied to specific systems, processes, and products are, by their nature, limited; while an agnostic platform will address current biomanufacturing business challenges and ensure future readiness. With the right platform, a phased automation implementation can yield operational efficiency gains of up to 30% and improved product quality and regulatory compliance.
In this webinar, let's explore:
• Challenges of automation and digital technology adoption
• What a product, process, and system agnostic platform entails
• Applications and benefits of a process orchestration platform
• Ensuring future readiness with process orchestration

Antibiotic Stewardship by Anushri Srivastava.pptxAnushriSrivastav
Stewardship is the act of taking good care of something.
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
WHO launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) in 2015 to fill knowledge gaps and inform strategies at all levels.
ACCORDING TO apic.org,
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
ACCORDING TO pewtrusts.org,
Antibiotic stewardship refers to efforts in doctors’ offices, hospitals, long term care facilities, and other health care settings to ensure that antibiotics are used only when necessary and appropriate
According to WHO,
Antimicrobial stewardship is a systematic approach to educate and support health care professionals to follow evidence-based guidelines for prescribing and administering antimicrobials
In 1996, John McGowan and Dale Gerding first applied the term antimicrobial stewardship, where they suggested a causal association between antimicrobial agent use and resistance. They also focused on the urgency of large-scale controlled trials of antimicrobial-use regulation employing sophisticated epidemiologic methods, molecular typing, and precise resistance mechanism analysis.
Antimicrobial Stewardship(AMS) refers to the optimal selection, dosing, and duration of antimicrobial treatment resulting in the best clinical outcome with minimal side effects to the patients and minimal impact on subsequent resistance.
According to the 2019 report, in the US, more than 2.8 million antibiotic-resistant infections occur each year, and more than 35000 people die. In addition to this, it also mentioned that 223,900 cases of Clostridoides difficile occurred in 2017, of which 12800 people died. The report did not include viruses or parasites

CRISPR-Cas9, a revolutionary gene-editing tool, holds immense potential to reshape medicine, agriculture, and our understanding of life. But like any powerful tool, it comes with ethical considerations.
Unveiling CRISPR: This naturally occurring bacterial defense system (crRNA & Cas9 protein) fights viruses. Scientists repurposed it for precise gene editing (correction, deletion, insertion) by targeting specific DNA sequences.
The Promise: CRISPR offers exciting possibilities:
Gene Therapy: Correcting genetic diseases like cystic fibrosis.
Agriculture: Engineering crops resistant to pests and harsh environments.
Research: Studying gene function to unlock new knowledge.
The Peril: Ethical concerns demand attention:
Off-target Effects: Unintended DNA edits can have unforeseen consequences.
Eugenics: Misusing CRISPR for designer babies raises social and ethical questions.
Equity: High costs could limit access to this potentially life-saving technology.
The Path Forward: Responsible development is crucial:
International Collaboration: Clear guidelines are needed for research and human trials.
Public Education: Open discussions ensure informed decisions about CRISPR.
Prioritize Safety and Ethics: Safety and ethical principles must be paramount.
CRISPR offers a powerful tool for a better future, but responsible development and addressing ethical concerns are essential. By prioritizing safety, fostering open dialogue, and ensuring equitable access, we can harness CRISPR's power for the benefit of all. (2998 characters)
Global launch of the Healthy Ageing and Prevention Index 2nd wave – alongside...ILC- UK
The Healthy Ageing and Prevention Index is an online tool created by ILC that ranks countries on six metrics including, life span, health span, work span, income, environmental performance, and happiness. The Index helps us understand how well countries have adapted to longevity and inform decision makers on what must be done to maximise the economic benefits that comes with living well for longer.
Alongside the 77th World Health Assembly in Geneva on 28 May 2024, we launched the second version of our Index, allowing us to track progress and give new insights into what needs to be done to keep populations healthier for longer.
The speakers included:
Professor Orazio Schillaci, Minister of Health, Italy
Dr Hans Groth, Chairman of the Board, World Demographic & Ageing Forum
Professor Ilona Kickbusch, Founder and Chair, Global Health Centre, Geneva Graduate Institute and co-chair, World Health Summit Council
