Variability, Limits, and Other Considerations for the Next Generation of Pyrogen

Full title: Insights into Practical Issues Associated with Extractables Testing of Medical Devices

It is a well-known adage that “the devil is in the details.” As authoritative texts and regulatory guidelines that address the chemical characterization of medical devices usually present concepts and generalities and lack granularity, sponsors seeking to design and implement extraction studies for medical devices occasionally struggle to establish and justify critical experimental details that are scientifically sound, practical, achievable, and regulatorily compliant.

This presentation provides insights into several of these critical experimental details, addressing concepts that include:

The “It all comes out at Once” Paradox

Exhaustive Extractions as a Source of Kinetic Release Data

Predicting Exhaustive Extractions with a Minimum Number of Extraction Steps

A Rational (?) Approach to Quantitation and Managing the AET

Accurate versus Protective Quantitation

What exactly is a “Semi-polar” Solvent?

Insights into Practical Issues Associated with Extractables Testing...

Presented by Clare Blue, Director of Biologics / Gene Therapy Development at Biogen, Ryan Smith, British Pharmacopoeia Specialist at Medicines and Healthcare products Regulatory Agency and Franz Schnetzinger, lead analytical development and QC at Gyroscope Therapeutics, A Novartis Company

The British Pharmacopoeia Commission is producing non-mandatory best practice guidance for analysing advanced therapy medicinal products (ATMPs). This guidance ensures regulatory compliance, patient safety, and industry innovation. Non-mandatory best practice guidance can enhance industry practices, especially in technical fields such as biotech. Vector copy number and empty capsid ratio analysis are crucial in gene therapy development, and accurate analysis is essential for safety and efficacy. Best practice guidance can provide a standardised approach for consistency and encourage innovation. Organisations can learn from each other and improve the quality of research and development. The webinar will cover two guidance documents: Vector Copy Number and Characterisation of the Vector Particle Population of AAV Products.

Full title: Navigating The Complexities of AAV Scale Up to Keep Pace with the Increasing Demand For these Viral Vector Delivery Systems

Modalis’ epigenetic editors are designed to efficiently target genes and control chromatin conformation by coupling an engineered Cas9 variant with epigenetic effector domains; referred to as GNDM (Guide Nucleotide Directed Modulation), which is delivered via a single AAV vector.

Most AAV capsids used for systemic treatments require high doses,

leading to safety concerns. To overcome such obstacles, Modalis has evaluated numerous novel AAV capsids allowing for reduced dosing, increased safety margins, and higher

therapeutic efficacy. These novel capsids do not always play nicely with standard manufacturing techniques and available reagents, so creative process development and analytics are needed to bring these promising therapeutic molecules to patients.

Full title: Evaluation of Optimal Extraction Conditions for Polypropylene, PBT Resins, and Chlorobutyl Rubber Elastomer - Using a Variety of Solvents and Extraction Conditions

Chemical safety assessment is one necessary step to demonstrate that the polymer used is free from harmful chemicals. The assessment should start with adequate material characterization using state-of-the-art analytical methods, including various chromatography techniques most often hyphenated with mass-spectrometric detection. Since polymers are usually incompatible with direct analysis using chromatography-based techniques, an extraction step is required prior to analytical testing. This paper provides information for practitioners who need to understand how to develop science-based extraction conditions that enable the determination of the polymer composition with respect to volatile compounds. Analytical data sets for three types of polymers (polypropylene, polycarbonate, polybutylene terephthalate, and a rubber elastomer) are presented using three different solvents and three different extraction techniques. The extracts were collected at different times during extraction and analyzed by GC-MS. The differences observed between extraction techniques, conditions, and solvents are discussed to better understand the impact of these parameters in extractable studies.

Quality and Compliance Requirements For Cell and Gene Therapy Products

Full title: Medical Device Chemical Toxicological Risk Assessments: Applying Toxicological Principles to Meet the Challenge

Medical device chemical toxicological risk assessment is challenging because the risk assessor often needs to consider the many types of device intended uses, many types of materials used in design and manufacturing, and many types of intentional and unintentional chemicals that are or could be present in the final finished device. Medical device intended uses include the type of tissue contact, the contact frequency and duration, and susceptibility of the device user to chemical exposure. Material factors include the material type (e.g., alloy, polymeric, ceramic, or natural), material properties (e.g., alloy surface characteristics, polymer plasticity, or polymer manufacturing process) and material chemical composition (e.g., chemical formulation, potent toxicants (if present), and the rate and duration of release). How to apply these considerations is described in the U.S. Food and Drug Administration (FDA) 2020 guidance Use of International Standard ISO 10993-1, “Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process”, International Standard Organization (ISO) 10993 series, and ISO 14971. This presentation will describe how chemical toxicological risk assessment fits into the overall medical device biological risk management process (i.e., risk analysis, risk evaluation, or risk control). Additionally, what medical device chemical toxicological information to consider from the U.S. FDA 2020 guidance and ISO documents when estimating chemical toxicological risk will be covered, such as: approaches for estimating an exposure dose, deriving a tolerable intake (TI), and other critical factors to consider that could be useful in the determination of whether exposure to a medical device chemical presents a tolerable risk or could present a possible toxicological risk.

Digitalization has been used in a lot of biopharma processes. A lot of data are collected through sensor and process measurement and already used in Machine Learning model. However, regarding Incoming material that may have a huge impact on final drug products not much has been done. Historically this was due to the fact that exchange of data with interfaces was quite difficult. This is changing. Through this Webex we want to show advantages of collecting such critical material data from supplier. We will discuss standard and tips on  how to collect data and interact with supplier regarding incoming material. Concrete examples on how GSK use such tools will be shown. Future trends on how digitalization could be applied to more specific  Incoming material such as Single Use will be developed. Example in the field of extractable and leachable, design or investigation will be explained with expected benefits. This will show you that a new world is opening to all of us with digitalization tools.

How Digitization Can Improve Bioprocessing and Make Manufacturing More Robust

During biopharmaceutical development large data volumes are generated in many stand-alone devices. Furthermore, with increasing projects and requirements to compress development timelines, high throughput and automation systems are being increasingly implemented. The resulting high pace of data generation augments error rates thereby risking data integrity.

This presentation will provide insights into the strategies and tools for data collection, storage and visualization to transform data into knowledge ensuring leaner, more efficient and integral data generation.

An assessment for each process step and equipment connectivity was performed to map, categorize and highlight gaps during data generation. Based on this preliminary assessment, a data architecture composed of multiple tools was designed to close gaps associated to data traceability, integrity & amp; extractability. Moreover, to support decision-making, multiple modelling tools were developed to focus on specific needs during process development, including process optimisation.

Through increasing instrument and system automation & amp; interconnectivity, data traceability, extractability and searchability are improved, and lab efficiency is increased by >20%. Moreover, with the use of mechanistic models, prediction of culture performance becomes a reality uncovering optimized feeding strategies to significantly increase productivity. In summary, our combined data architecture and process modelling techniques provide better insights thus improving process understanding while accelerating process development.</p>

The road to digitalisation of a research Lab

Presented by Johannes Scheiblauer, Associate Scientific Fellow for Digital CMC at Takeda and Sean Bermingham, Head of Formulated Products at Siemens

Several enabling technologies change the way we do pharmaceutical development: automation & digitalization, advanced analytical methods, modeling & simulation. But especially the latter are not silver bullets, and it is important to have a closer look why and when one might use them.

In this presentation, we focus on the real-time applications of modeling & simulation in the context of process monitoring & control: how to leverage the underlying technologies to better visualize current process data, improve process control decisions and anticipate future process trajectories.

We discuss factors and prerequisites supporting a successful and sustainable implementation, from the “digital maturity” of the processes over the necessary technical building blocks (like robotics & high-throughput experimentation) to aspects of people mindset and change management: what it means for an organization to embrace these new ways of work.

Deploying Modeling & Simulation to Enable Advanced Process Monitoring & Control

The confirmation of microbial quality of drug products manufactured by contract manufacturing organisations (CMOs) is a key component of product release.  Whilst the responsibility for product release may lie with the CMOs quality organisation, the sponsor is required to ensure the appropriate quality of the article. 

 Compendial methods for microbial enumeration and sterility are provided in the harmonised pharmacopeia’s (USP, Ph Eur, JP1,2,3), however within the framework of the  compendial chapters, there are a variety of approaches which can be made to meet the requirements.

Whilst compendial methods provide a starting point to define a product specific method, the presence of the test article can lead to interference with the proliferation and detectability of microorganisms.  It is essential the product specific method is demonstrated to be suitable in the laboratory that is conducting the routine testing.

During this webinar you’ll hear an overview of the different approaches to meeting the compendial requirements for the tests for sterility and microbial enumeration.

Full Title: De-bottlenecking Challenges in Large Scale Viral Vector Manufacturing for Gene Therapy Applications

The rush to develop an affordable and accessible COVID-19 vaccine not only accelerated research and development of therapeutic modalities like viral vector, mRNA and pDNA based vaccines but also challenged the bioprocess community to solve for unique scale-up related challenges to manufacture these important life-saving medicines. 

Adenoviral vectors are attractive vectors for delivering genes for other gene therapy applications. These vectors can accommodate large transgenes, transduce quiescent and dividing cells, and do not integrate into the host’s genome. Adenoviral vector technology using HEK293 host cells has been around for a long time and the manufacturing process includes upstream processing (HEK293 cell culture and viral infection), followed by series of clarification, filtration, and chromatography steps to produce drug substance with high purity. Although, the process unit operations seem uncomplicated, manufacturing at large scale in single use systems has remained a major challenge due to poor and inconsistent cell growth in suspension culture during scale-up, low viral titers, product aggregation, inefficient separation of empty and filled viral capsids, as well as complexities related to handling large volume viral infection. Hence, there is a strong requirement to build robustness and scalability in early process development to minimize unnecessary late-stage process changes, as well as design cGMP facility and strong quality culture to handle operational complexities and reduce risks associated with viral vector manufacturing. The webinar will illustrate key questions and challenges in large -scale manufacturing of viral vectors from a process robustness, facility design and product quality standpoint as well as our experiences in debottlenecking these challenges to scale adenoviral vector technology at 2000L and beyond.

The metabolic state of mammalian cells in a bioprocess can be monitored by high-resolution optical systems or by changes in dielectric properties. Each method can determine a metabolic inflection points just prior to loss of cell viability.  Such changes can be observed up to 20h before cells stain with trypan blue.  We have established a threshold of cytoplasmic conductivity below which cells cannot be recovered from apoptosis. This point occurs at a time when there are observable changes in the cell membrane that can be detected by high-resolution optics.   This early detection of metabolic changes allows dielectrics and high-resolution optics to be offered as a means of monitoring a bioprocess and maintaining cell viability over prolonged time periods.
