Integrity testing is a critical operation, especially for sterilizing grade filters used in biopharmaceutical processing. When performed correctly, an integrity test is a fast, definitive, non-destructive way to assure filter retention performance. Fortunately, there are few ways a non-integral filter will pass the integrity test, eliminating the possibility a non-retentive filter is used undetected. Unfortunately, there are a lot of ways an integral filter can fail the integrity test, resulting in retests, lost time, productivity and potentially lost product.
In this webinar you will:
- Gain confidence in your integrity testing results
- Provide justification for retests
- Understand specific challenges and eliminate them to assure the integrity test can be performed correctly the first time

Quality by Design Principles Applied to Sterilizing Filtration by Michael PayneMilliporeSigma
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.
The two most commonly used within microbiology are
HACCP (which originated in the food industry) and FMEA
(developed for engineering). This article explores these two
approaches, first with a description of HACCP, followed by a
description and case study of FMEA in sterility testing.

Single-Use Tangential Flow Filtration for Closed ProcessingMerck Life Sciences
Watch the presentation of this webinar here: https://bit.ly/3b7vD60
Closed processing involves use of physical barriers to separate processing fluid from the external environment. This approach reduces capital expenditures and clean room classification while accelerating time to market. This webinar will present a TFF process run in a closed mode.
Closed processing with single-use technologies is a critical enabler for efficient and robust manufacturing for novel modalities as well as continuous biomanufacturing processing. It can also reduce the dependence on classified clean rooms for traditional modalities. This approach helps to mitigate the risk of contamination by adventitious agents while enhancing operator safety.
In this presentation, we discuss the implementation of closed processing for downstream applications and present the design and performance testing of a single use manufacturing-scale tangential flow filtration system to be able to operate in both functionally and fully closed mode.
In this webinar, you will learn:
• The context of closed processing
• Differences between closed and functionally closed processing
• The drivers for adoption
• Its practical implementation to a TFF step

Watch this webinar here: bit.ly/asepticwebinar2020
In this webinar, you will learn:
- The challenges tied to contamination control within a biopharmaceutical environment.
- What closed processing is, and how sampling solutions are an integral component towards that end.
- Advantages of sterile sampling from both a technical and economical viewpoint; with the review of a technical study confirming contamination risk reduction and total cost of ownership.
- Recommendations and requirements stated by these major regulatory authorities around the monitoring of the manufacturing process with the execution of sampling.
Detailed description:
Biopharmaceutical manufacturers are required to ensure drug product quality attributes for patient safety. Strong contamination control strategies should be considered early in process design, and have direct influence on the production environment and equipment selection.
Sampling at each step is a critical component in maintaining a contamination control strategy. Regulators are critical in the sampling process, as it predicts the state of the product or process, and needs to be Representative. A case study will be presented that demonstrates a closed, robust sampling solution capable of maintaining a sterile flow path when challenged with Brevundimonas diminuta. The sampling option you select can help support your goal in achieving a closed process, improving your risk mitigation strategy and product safety.

An Efficient and cGMP-friendly Solution to Diafiltration for Intensified or C...Merck Life Sciences
View the recording here: https://bit.ly/2M6cTYD
Abstract:
Diafiltration is a critical unit operation in the downstream purification train for nearly all monoclonal antibodies and other therapeutic biomolecules, with a particular application being the final formulation step. It provides a cost-effective, efficient, and robust method for achieving > 3 logs of buffer exchange. As the biomanufacturing industry strives for more efficient and cost-conscious processes and facilities by adapting templates to be more flexible, handle larger batch sizes, require lower plant footprint, and run in an integrated or continuous mode, diafiltration has been one of the last unit operations to change. Updated technologies for chromatography, clarification, and concentration have been developed in recent years, offering significant improvements over their existing batch processing equivalents. However, it has been challenging to develop a similar intensified and continuous technology for diafiltration that exceeds established expectations around unit operation productivity while maintaining a process that is easily implementable and suitable for GMP manufacturing.
Our approach to intensified, continuous diafiltration bases the process design on membrane utilization, as opposed to flux and process time typically used for batch designs. The result is a flexible solution that offers 6-8-fold decrease in membrane area, up to 3-fold reduction in pump passes and a substantial footprint reduction. Buffer usage, extent of buffer exchange, and product yield are equivalent to a traditional constant-volume diafiltration process. The process development approach, system components, and process control rely on well-established methods and technologies, reducing risk during scaleup and manufacturing implementation.
In this webinar, you will learn:
- A new process design for continuous diafiltration and its operational robustness over a 24-hour run
- Benefits of implementing this version of intensified or continuous diafiltration in your process train

Sterile filter validation is an important process in the pharmaceutical, biotechnology, and healthcare industries to ensure the effectiveness and integrity of sterile filtration systems. The validation
process involves testing and verifying the performance of sterile
filters to ensure they can effectively remove microorganisms and

a sterilizing grade filter requires consideration of many important
issues, such as materials of construction and their compatibility
with the product to be filtered.

Innovation in Filter Validation and Technology TransferMilliporeSigma
Regulatory and manufacturing requirements exist to perform product-specific microbial retention testing on sterilizing filters. The implementation of a Quality by Design approach to microbial retention testing supports a paradigm that would obviate the need for product-specific testing for early stage products that do not have the quantity of material required to easily and efficiently perform such testing. Process and product parameters were varied to determine their effect on microbial retention.

The Viscosity Reduction Platform: Viscosity-reducing excipients for improveme...Merck Life Sciences
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

time/total time filter is in contact
with fluid
Discard filter after processing of a
single lot
Don’t use filter for more than one
working day (unless validated)
Conduct and document effective
validation and qualification studies
to demonstrate that the duration of
filter use does not compromise
performance of the sterilizing filter
or filtrate quality
Sterile filtration should be
validated
− validation can be grouped
− but done under worst case
conditions
− rationale for grouping justified
and documented
Filter validation wherever possible
with product
Justify challenge organism used in
bacterial retention test
Establish appropriate integrity test
value specification
Filter selection
− minimize generation of
fibers and particulates
− no unacceptable levels of
impurities
− compatible with the fluid
− evaluate adsorption and
extraction/leaching
Filtration concept (serial,
redundant, bioburden
reduction)

“Filter validation
Acceptable information has been provided
during the procedure for filter validation on
the filters used for sterile filtration,
describing the material, pore size and
surface area. All study results met the
predetermined acceptance criteria and the
studies for microbial retention, membrane
compatibility, extractable substances and
integrity test determination have shown
that the filters are appropriate for sterile
filtration of the finished product.”

34. Definitions - What are the differences ?
Single use versus multiple use
34
In draft Annex 1 : Point 8.95
‘Liquid sterilizing filters should be
discarded after processing of a single
lot and the same filter should not be used
for more than one working day unless
such use has been validated’
& NEW Point 8.96
‘Conduct and document effective validation
and qualification studies to
demonstrate that the
duration of filter use for a given
sterile filtration process and for a given
fluid does not compromise
performance of the
sterilizing filter or filtrate quality.’
1 Single use : discard of the filter after one batch
2 Multiple use # A: filter is re-used for multiple batches with
no cleaning and/or sterilization between batches
3 Multiple use # B: filter is re-used for multiple batches with
a cleaning cycle but no sterilization processes between
batches
4 Multiple use # C: filter is re-used for multiple batches
with sterilization processes between batches
35. Integrity/sterility failure
Additional hydraulic stress over long process duration & multiple filter blow downs.
Additional thermal stress when multiple sterilization cycles.
Chemical incompatibility; filter material degradation accelerated by product residual compounds heated
during multiple sterilization cycles.
Bacteria concerns during long product wet hold periods between batches
Product quality concerns (addressed by filter user)
Influence of cleaning solutions on product quality
Product contamination / carry over
Increase of endotoxin level
Potential risks
Single use versus multiple use
35
These risks could be mitigated by a well-designed filter validation strategy
