TITLE AND ABSTRACT

Worst case conditions for virus retentive filtration

Viral clearance studies (VCS) are one of the essential parts of a manufacturer’s program to ensure product safety since 1997.

Since the implementation of VCS it is appeared that the most robust step in removing viruses is the virus retentive filtration. For market authorization or biologic license application studies one should run the filtration at set-point conditions or under the worst case. Is this worst case always so well defined?

Looking at the data obtained in the recent years and performing experiments we want to shed a bit more light into what can be considered as worst case.

TITLE AND ABSTRACT

Testing and optimization of various load conditions using the Planova BioEX to improve filterability and throughput of a client specific Mab that showed difficulties using our platform viral filtration approach

A client specific Phase I Mab using the Fujifilm platform downstream approach blocked the platform virus filter almost instantaneously, during an initial laboratory assessment run through. A very small throughput was observed of this difficult to virus filter client specific Mab on a Asahi Kasei Planova virus filters 20N and BioEX, an alternative filter to our platform approach. Although the aggregate profile by size exclusion chromatography of the unconditioned Mab was within expectations, sub visible particles were reported in the hands of the formulation group in Fujifilm, North Carolina. In collaboration with Fujifilm formulation group and Asahi’s data on BioEX improved filterability using additives, various load conditions, Mab concentration and different pre filters were tested in the Wilton labs, UK to improve throughput and filterability of this Mab through the Planova BioEX such that it is a scalable process for this Mab to GMP 2000L batch.

In this presentation, the various range of load conditions that were tested on the BioEX filter and different types of pre-filter used is discussed for this client specific difficult to filter molecule. A final chosen condition is tested at 10L scale for both fresh and freeze thawed virus filtration load material prior to scale up to pilot scale 200L. Various scales of the BioEX filter 3cm2, 100 cm2 and 1000 cm2 are used in this work and performance at different scales in a laboratory setting were within expectations.

TITLE

Comparison of Planova membranes with respect to process performance and virus removal

A study was performed comparing the Planova 15N, 20N, BioEX and S20N virus filters on filtration performance and viral clearance capability. Two monoclonal antibodies comprising different characteristics were used. The virus filters were tested in several positions in the downstream process, more specifically before and after the final ultra/diafiltration unit operation. Data demonstrate the capacity, especially of the Planova BioEX and S20N filters, to process high amounts of mAb in a short time, although the flux and flux decay vary and are mAb dependent. Viral clearance results show excellent virus removal.

TITLE AND ABSTRACT

An end2end process for continuous biomanufacturing of antibodies using precipitation and membrane technology

The biopharmaceutical industry still operates in a batch process, mainly because it is a highly regulated industry, but there is increasing economic pressure on time-to-market and also on the environmental sustainability of biopharmaceutical production and facilities. New approaches to manufacturing using single-use technologies are increasingly being implemented, and production is shifting from dedicated production suites to large-scale facilities capable of manufacturing multiple products. Integrated, continuous biomanufacturing will accelerate and drive these developments by providing a way to reduce the footprint of a manufacturing facility and shorten the time required to produce clinical batches. A novel way to manufacture biopharmaceuticals through an integrated continuous biomanufacturing process that is not a mainstream technology is presented. The process consists of continuous fermentation using perfusion cell culture, precipitation, precipitate recovery by continuous membrane separation, flow-through chromatography, and continuous virus filtration. The advantage of this process is that it integrates the individual steps without a surge tank and therefore the residence time distribution is very narrow, resulting in fast start-up and shut-down times. The purification of recombinant antibodies is demonstrated, and the economic and environmental implications are discussed. This technology could significantly change the future of upstream and downstream processing of recombinant antibodies and other biopharmaceuticals by reducing the size of production facilities, improving process economics and environmental footprint, and eventually is the basis for autonomous bioprocessing.

TITLE AND ABSTRACT

Evaluation of Planova™ S20N virus removal filter using plasma-derived products

A wide variety of virus removal filters are presently available on the market. It is well known that virus removal filters are one of the most effective devices to ensure the virus safety of plasma-derived products. This is attributable to the relatively clear mechanism of virus removal. Furthermore, the factors that could affect filtration is limited. However, users should understand the characteristics and limitations of each product and independently determine the optimal conditions.

PlanovaTM S20N (S20N) is a new virus removal filter that was released in 2021 from Asahi Kasei Medical. S20N has been announced to achieve high filtration performance and virus removal capacity. We evaluated the filtration performance and virus removal capacity using our plasma-derived products and Canine Parvovirus (CPV) as a key model virus. In this presentation, I show our data that compares S20N to other Asahi Kasei-produced filters.

TITLE AND ABSTRACT

Process design to obtain robust filterability in virus filtration step for monoclonal antibody

Filterability is one of the key factors in establishing a robust and high-throughput manufacturing process for virus filtration of biopharmaceutical products including monoclonal antibody (mAb). To improve a virus filtration step, optimization of feed solution conditions and filter selection are essential.

Our study investigates the filterability of Planova™ 20N, BioEX, and S20N filters in mAb feed solutions with 15 different configurations of protein concentration, pH, and NaCl concentration selected by design of experiments (DOE). The DOE results in this presentation will provide valuable insights into the design space focusing on filterability for each Planova filter. These insights obtained from comparing the characteristics of each Planova filter would be beneficial for optimizing feed solution conditions, selecting the appropriate filter, and predicting filterability.

TITLE

Structural and functional insights into the next generation cellulose virus filter membrane with IgG feed stream

Removal of potential viral contaminants by nanofiltration is a commonly applied step during the manufacturing of biotherapeutics. Membrane fouling and flow decay pose a significant challenge for most types of filters and can lead to limited throughput, increased filtration time, and viral breakthrough. The Planova S20N is a recently developed cellulose-based virus filter membrane, which aims to overcome limitations of previous generations of filters. To obtain the first mechanistic insights into the Planova S20N membrane, the filter was challenged with fluorescently labeled virus-like particles of minute virus of mice (MVM), murine leukemia virus (MuLV), and human immunoglobulins (IgG), followed by visualization using laser-scanning microscopy. The retention profiles unveiled a size-specific retention of the particles at distinct filter depths, suggesting a highly selective separation of the particle species along a uniform pore size gradient. Fouling experiments were performed with increasing amounts of IgG molecules causing a concentration-dependent flow decay; however, without significant changes in the retention profile of the foulants. Importantly, MVM was effectively captured within the retentive zone during filtrations at constant convective flow and with multiple flow interruptions. Virus filtration studies performed with an IgG product intermediate underlined the improved membrane attributes in a relevant industrial setting, allowing for a higher throughput while assuring effective virus retention. Taken together, these first mechanistic insights into a next generation filter membrane provide a deeper understanding of the underlying structure-function relationship and the knowledge aids in the advancements in process performance.

TITLE

Contribution of alternative cell retention filter to the overall output in perfusion processes

During the development of a second-generation perfusion process of a currently marketed API, the selection of a more adequate cell retention device allowing for an increased product transmission was underlined among the possible contributing factors to improve.

Screening of commercially available alternatives allowed for the identification of a specific filter that showed 100% transmission of the product through the membrane throughout the whole cultivation process. However, although a 40% increase in product yield was obtained at manufacturing scale for the current process, some wrong assumptions made during the scale-up of the process hampered the implementation of the alternative filter, since several product CQAs were impacted.

These learnings were taken into consideration during process development and could finally be solved by the introduction of additional changes both upstream and downstream, allowing for a final overall 6X increase in process yield of the second-generation of a currently marketed API.

TITLE

Enabling Commercial Continuous Manufacturing of Biologics through Upstream Innovation and Facility Design

Continuous Manufacturing (CM) of therapeutic proteins has progressed from proof of concept, through technology maturation over the course of the past decade and is currently in the adoption phase of its lifecycle. Not only have process development and process characterization workflows been established, but also manufacturing networks have been stood-up to support molecules moving through company pipelines using the CM paradigm. As a result, commercial production of therapeutic proteins with continuous manufacturing is within reach by the biotechnology community. At MSD, a therapeutic protein platform has been deployed from production in a perfusion bioreactor through bulk purification, fine purification, and virus filtration resulting in ultrafiltration product with the intent to deploy for use commercial manufacturing.

To establish commercial readiness and support its pipeline of therapeutic proteins, MSD has invested in establishing the CM platform in our existing clinical production facility. Upon establishment of the CM platform, a multi-batch cGMP campaign was completed to prepare relevant clinical supplies. Leveraging this accomplishment, MSD has also broken ground on a new next-generation manufacturing facility focusing on continuous manufacturing process technologies and incorporating intelligent facility design concepts to enable maximum flexibility allowing for continued diversity in the research pipeline.

This presentation will focus on scalability of the MSD CM platform from the lab-scale for process development, through pilot scale for toxicology supply, to cGMP production at intermediate scale for clinical supply. In addition, pain points and success stories from scaling the CM process to clinical production will be highlighted along with PAT integrations focusing on the perfusion bioreactor and its cell retention device. Finally, aspects of the next generation facility design will be discussed including the use of podular manufacturing spaces for flexibility and future capability expansion and automation design to enable rapid and seamless process transfers from lab to clinical to commercial nodes. With adherence to these principles, we intend to ease the transition to GMP continuous manufacturing processes while building a next-generation manufacturing network to meet commercial demands.

TITLE AND ABSTRACT

Viral Clearance Strategies and Considerations for AAV-based Gene Therapy Products

Gene therapy delivery using adeno-associated virus (AAV) continues to make strides clinically and has the opportunity to impact patients suffering from devastating genetic diseases.

As the quantity of INDs and approvals continue growing, AAV-based viral safety considerations have become a topic of interest. Production occurs in multiple cell culture systems (human / non-human, virus-assisted / transient transfection). The type and risk of viral contamination can be specific to each platform and limits the ability to implement a universal approach. Additionally, viral clearance validation presents a unique challenge as the product is itself a virus.

The work presented will highlight the approach Alexion took to build viral safety into their AAV manufacturing platform and will discuss a case study where viral safety was improved through changes in both the upstream and downstream manufacturing process. Research viral clearance studies for multiple AAV products established the capability of the purification process to remove adventitious viruses.

TITLE AND ABSTRACT

Optimizing Advanced Process Control Strategies and Viral Filtration Operations for Continuous Manufacturing for Biologics Processes

Switching from standard fed-batch (FB) processes to intensified continuous manufacturing (CM) can significantly improve the efficiency and cost-effectiveness of monoclonal antibody biologics production. CM processes offer higher volumetric productivity, with 2 to 5-fold higher cell density and shorter cultivation duration.

One key difference between CM and traditional FB processes is the importance of advanced process control. CM processes are designed to operate continuously, with uninterrupted medium exchange and perfusate flow supply from upstream to downstream. This is made possible through interconnectivity and unit linkages, where downstream flowrates are determined by the perfusate titer using process calculation tools. Instead of relying on large hold intermediate tanks, CM processes utilize smaller surge vessel tanks between unit operations to manage process pauses and maintain flow continuity. This approach reduces the overall footprint of the manufacturing process.

The ability to withstand process pauses becomes crucial in ensuring viral clearance in CM. Specifically, it is important to evaluate whether commercial viral filters can handle anticipated low flux conditions and potential pressure interruptions. A case study was conducted using minute virus of mice (MVM)-spiked feeds and small-scale hollow fiber virus filters with hydrophilic modified polyvinylidene fluoride (PVDF) membrane. Low flux, high volumetric throughput, filter fouling and process interruptions had minimal impact on overall MVM log-reduction virus (LRV) achieving >4 log reduction when running continuously up to 6 days. This work was completed for Planova BioEX and plans are underway for Planova S20N by 2024.

Small-scale data can inform decisions on filter selection and establish criteria for filter switching in continuous manufacturing. These case studies demonstrate the feasibility of using commercially available virus filters in GMP processes and highlight the potential for overcoming unique challenges through tailored process design, ultimately increasing operational flexibility and advancing on process control.

TITLE AND ABSTRACT

MOTIV Application at Lonza Biologics (Portsmouth, NH)

Management of buffers in biologic purification has been steady state for decades, without much in the way of innovation. Use of systems capable of point of use formulation and dilution using highly concentrated stock solutions present an opportunity to reduce equipment, footprint, and resources as manufacturing processes scale up.

At Lonza we have applied the MOTIV system in a way that has seen significant reductions in plastic waste, equipment usage, facility footprint, and human resource required to supply buffer needs in a new state of the art multi-product facility. Collaboration between Lonza and Asahi is ongoing with a focus on continuous improvement with the system.

In this presentation, Lonza Portsmouth’s overall experience with MOTIV will be discussed including benefits, considerations, challenges, and ongoing collaboration.

TITLE AND ABSTRACT

Addition of nanofiltration step at early bioprocess development stage

The viral safety of products intended for clinical trials is a priority. Because adventitious viruses present in original materials can contaminate biologics during processing, manufacturers must follow regulatory requirements to ensure adequate virus removal. Viral clearance data must be generated to support the safety of products for clinical trials. Earlier the viral clearance steps are introduced into the process, easier is for building the overall biologically safe process for future commercial product.

The nanofiltration is an effective and robust viral removal step based on the size-exclusion mechanism. Nanofiltration is known to effectively remove wide range of viruses (envelope/non-envelope, large and small in size, DNA and RNA types). In this presentation, the goal was to select the right filter product for target molecule based on filter performance with the aim to evaluate the viral clearance capacity of the selected filter in consequent studies. The throughput, filterability (yield), process time (Flux), and matrix compatibility (buffer/product) at different load concentrations were investigated for six (6) different filters from four (4) different vendors. Based on the results, amongst six (6) tested filters, Planova S20N has been identified as the best performer, thus it was selected for viral clearance evaluation.

TITLE AND ABSTRACT

End-to-end continuous process for mAb purification implementing total flow-through integrated polishing process

There are few reported examples of continuous processes, particularly fully end-to-end continuous processes adopted in the actual bioproduction, because of difficulties such as feed adjustment, production batch definition, and incorporating the continuous virus filtration process. For these difficulties, we propose an end-to-end continuous process by performing low-pH inactivation in a pool with automatic pH control and incorporating total flow-through integrated polishing process directly connecting two columns and a virus filter.

It was confirmed that high HCP reduction, mAb recovery and quite stable virus filtration were realized with feed adjustment and clear definition of production batch. The inline spike viral clearance tests were practiced with two different types of virus for virus filters implemented in the integrated process and confirmed robust virus reduction at the constant flow rate loading even after 60 min process pause.

The end-to-end continuous process proposed in this study is highly effective for practical mAb production processes and investigated virus filters have excellent applicability to the continuous processes operated at constant flux.

TITLE AND ABSTRACT

Proof of Concept Performance with Planova S20N Novel Virus Removal Filter, “Processing more, Faster”.

Planova is the world’s first virus removal filter launched in 1989. Planova has emerged as a technical breakthrough in the biopharmaceutical industry to assure robust viral safety. To further meet a market needs, novel Planova filter— Planova S20N using regenerated cellulose with improved pressure resistance were first launched in 2021. Due to improved pressure resistance, Planova S20N can operate with high transmembrane pressure leading to higher throughput while maintaining traditional Planova capabilities of robust virus removal capability and stable protein filterability over a wide range of solution conditions. After two years of small scale Planova S20N release, several in-house and customer experiments revealed and characterized its performance with their process in a variety of evaluation conditions. Here, I would like to share with you one of preliminary result which shows “proof of concept” gained from these evaluations.

TITLE AND ABSTRACT

Virus Safety against Emerging Viruses: History and Advances of Challenges in Viral Filtration Technology

Emerging viruses, as exemplified by COVID-19, are a global concern and a challenge that must be addressed on an ongoing basis. Since the 1980s, we have been facing emerging viruses such as HIV and HCV with membrane-based virus filtration technologies, developing optimal membranes and providing them to the market.

In addition, we have been collaborating with Paul Ehrlich Institute , pharmaceutical companies, and other external organizations on various emerging viruses such as Zika, HEV, and Corona virus, which have been reported since the 2010s, and have accumulated knowledge on their characterization and filtration removal to contribute to ensuring the safety of biological products.

The history and advances of our studies on improving safety against emerging viruses using filtration technology are discussed.

TITLE AND ABSTRACT

Numerical calculations of membrane structure, virus removal performance, and filtration behavior of virus filters based on a heterogeneous membrane structural model comprising multiple layers with different pore size distributions

Virus filters are essential in bioprocessing for safe protein production. These filters are designed to reject virus particles but allow the protein product to be recovered in the permeate. Understanding the correlation between virus filter structure and performance is important for efficient process design. Here, an advanced multilayer structure model is applied to virus filtration experimental data in order to analyse virus reduction. By applying a multilayer structural model comprised of theoretical layers having pore size distributions to published visualization data, we demonstrate in the present study that virus removal performance and filtration behaviour can be quantitatively calculated. Virus filter structure can be classified into asymmetric high porosity, symmetric high density and laminated structure types, and all types exhibit sufficient virus removal properties when used in normal processes. Laminated structure filter shows extremely high virus particle removal performance, achieving the most robust virus removal even in filtration with process pauses, although flux decay tends to occur during filtration of solutions containing even very small amounts of aggregate. Conversely, asymmetric high porosity filter may show the lower virus removal in processes involving multiple pauses that exceed practical conditions but shows stable filtration behaviour with lower increase in pressure increase and lower flux decay even for the filtration of solutions containing aggregates. Such filtration behaviour and virus removal properties can be quantitatively expressed and predicted by numerical calculations in models based on the theoretical multilayer structure.calculated curve showed good coincidence with experimental curve.
