BioPharma Webinars aims to keep its global audience abreast of all developments in the areas of Drug Development, Manufacturing, Quality Assurance, Outsourcing and Regulatory Affairs, with only the highest quality webinars, presented by the most respected people, working with companies in Pharmaceutical, Biopharmaceutical, Biologics and Biotech Industry.

Detection of bacterial endotoxins is a critical quality attribute of parenteral pharmaceuticals and medical devices.  Bacterial endotoxins are cell wall components of Gram-negative bacteria, ubiquitous in nature, difficult to destroy and can cause pyrogenic responses or worse.

We are at a generational change in bacterial endotoxins test method options.  Creating the infrastructure to enable broader use of recombinant reagents advances the science while maintaining the safety and quality of medicines.  Recombinant reagents are derived from established biotechnology principles which begin with the same mechanism of action as the natural protein derived from horseshoe crabs; the detection of bacterial endotoxins by the Factor C protein.  Recombinant reagents also afford improvements in quality, supply chain, and sustainability.

The USP Microbiology Endotoxin and Pyrogens Subcommittee developed a recombinant reagent bacterial endotoxins test chapter which is based on the underlying science, and data from the peer-reviewed literature, sponsor and supplier validations, and ring study trials.

The presentation will provide a general overview of the Subcommittee work, and detailed information regarding the recombinant bacterial endotoxins chapter, associated guidance, and the public health reference standard endotoxin.

Effective Extractable & Leachable Study Design

The demand for Advanced Therapy Medicinal Products (ATMPs) to treat diseases continues to grow, and, for many patients, ATMPs represent the last treatment option. As a result, it is crucial for manufacturers to produce and deliver these therapies in a timely manner while ensuring they meet all required safety and efficacy standards.

With the introduction of new manufacturing and testing methods, such as automation, decentralized models, and rapid testing; adopting a risk-based approach for testing and releasing ATMPs is no longer optional—it is essential.

This webinar will examine the potential risks involved in enabling just-in-time or real-time release of ATMPs. We will assess each stage of an example traditional autologous manufacturing process and identify potential risks and the factors that could allow for more efficient, timely release of these therapies.

While the webinar will focus on autologous manufacturing as an example, the insights shared can also be applied to other manufacturing methods.

Analytical Assessment of Leachables in Biological Drug Products: FDA Approach in Reviewing Information

Cell and gene therapy (CGT) is particularly well-suited for the application of big data analytics.  Although our understanding of these complex therapies remains limited, CGT manufacturing processes and analytical methods generate substantial datasets that can be analyzed using artificial intelligence and machine learning algorithms. These advanced computational tools are instrumental in identifying critical characteristics of novel CGT products, optimizing manufacturing and analytical methods, and defining predictive biomarkers, among other applications. This presentation will discuss the role of big data in the development and manufacturing of CGT products and will explore opportunities for crowdsourcing data in the precompetitive space.

Big Data Strategies for Cell Therapy Manufacturing

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.

A Quality by Design (QbD) Approach to Microbial Retention Validation of Sterilizing Filters

Continuous capture chromatography is a chromatographic technique promising higher efficiency through higher resin utilization, higher productivity and lower buffer consumption compared to batch chromatography capture processes.

Designing cSMB processes is more challenging than designing standard batch processes because each chromatographic phase is influenced by the previous phase. An iterative approach can be used to identify optimal conditions.

Our traditional process design approach was based on single column breakthrough curves and feeding the breakthrough data into a model. However, this concept leads to a sub-optimal process as it is based on a single loading flow rate during all phases, while effectively, flow rates and volumes in interconnected and parallel load phases should be different for an optimal process. In this webinar, I will present an approach where different flow rates and different breakthrough curves are used as model inputs together with pressure-flow dependencies for the resin of interest. Using the improved process design, significantly higher productivities were achieved compared to the standard procedure. The effect was confirmed for a given in-house model process with approximately 50% higher productivities which has been confirmed at laboratory scale. Finally, implications of the new cSMB design approach for large-scale manufacturing are discussed.

Optimisation of Continuous Capture Chromatography Processes

There has been much speculation and discussion of the universe of organic extractables; its size, its constituents, the nature of those constituents, etc. Knowledge about the universe is critical to establishing best practices for E&L.

In an effort to at least start the process of charting the organic extractables universe, Nelson Labs addressed the question of “what do we know about the universe from experience within that universe?” by performing a retrospective review of the many extractables studies that it has performed in the last several years. Study results were reviewed to establish what organic extractables had been reported in the studies performed over that period of time and how often the individual extractables were reported. Additional information about these extractables, including the methods they were detected with and their key analytical characteristics [e.g., relative response factors, retention indices (for GC/MS compounds) were abstracted from the compiled data and physiochemical characteristics of the extractables were collated from various sources.

The results of this data collection and analysis process will be discussed and the use of the information to establish best practices will be considered.

Read Across Assessment for Potential Leachables Without Toxicological Data

USP <86>, “Bacterial Endotoxins Test Using Recombinant Reagents” states, “Regulatory authorities may require supplemental data prior to acceptance…An example of supplemental data may include a comparative study of the material tested by techniques described in this chapter and those in 〈85〉.”  The term, “supplemental data” may refer to the use of a statistically robust analysis of test results obtained from a single sample containing assayable levels of endotoxins activity, using both the predicate assay (<85>) and the candidate recombinant assay (<86>) .

This webinar discusses the difference between 50-200% acceptance testing and statistical equivalence.  In addition, using data in the public domain as examples, the speakers will stress the importance of using a split sample containing assayable levels of contaminating or potentially contaminating endotoxins activity as the test article for these studies.

Advancing Cell & Gene Quality Control with GMP Next Generation Sequencing (NGS)

Using risk management to design aseptic process simulations:

Annex 1 states that “QRM (Quality Risk Management) applies to this document in its entirety”. Does this mean we can use QRM to justify non-compliance with Annex 1 requirements? The answer here is obvious: No.

So when and where can we use QRM? And for what purposes?

During this webinar we will go through several real and practical examples for using QRM to design Aseptic Process Simulations (media fills): 1) When using QRM is not allowed, 2) When it is permitted; and 3) When it is mandatory.

Using Risk Management to Design Aseptic Process Simulations

Establishing a personnel monitoring (PM) program requires a risk-based approach per the current EU Annex I. Presently, there is no specific industry or regulatory guidance on how to establish sample locations and sampling frequencies using Quality Risk Management (QRM) for personnel monitoring and the methodology behind a risk-based approach can vary greatly from site to site. Implementing a global risk-based methodology is desirable for consistency.  Takeda has developed a global personnel monitoring risk assessment tool that can be used across a range of production facilities.  This tool applies to both gowning qualification sample site determination and routine personnel monitoring associated with batch production.  Utilizing QRM principles, contamination hazards and sources were identified and assessed to inform risk scoring criteria.  The personnel monitoring assessment takes into consideration the process understanding of both gowning and manufacturing operations. A case study for the application of the risk-based tool will be presented.

The principles for developing traditional biologics are well established, but do not always translate well to cell and gene therapy products.  Creative yet practical adaptations are necessary to advance gene therapy programs toward licensure.  During this presentation we will explore three key areas where practical adaptations are required:

Building toward the commercial process: change control and managing product evolution for non-traditional development pathways, comparability challenges, and regulatory expectations

Maturation of analytics – the level of product understanding expected as programs advance, method advancement from early to late phase, ensuring repeatability and robustness in method performance

Finding the right partners – finding the right match in terms complementary capabilities, technical performance, phase-appropriate GMP compliance and client service infrastructure

CMC Progression from Early to Late Phase – Practical Considerations for Gene Therapy

This webinar will provide an in-depth exploration of a QbD-based method development approach for quantifying host cell DNA in gene therapy products, a critical quality attribute to ensure product safety and regulatory compliance. The session will begin by examining the measurement principles of two widely used techniques: qPCR and dPCR, while highlighting their respective advantages and limitations. A central focus will be on establishing a robust conversion factor for dPCR implementation. This factor is critical for accurately converting results from copies/μL, the standard dPCR output format, to ng/dose, as required by regulatory guidelines. The discussion will emphasize the importance of selecting an appropriate target gene and utilizing reliable reference materials to ensure precise reporting. Additionally, the webinar will address other essential aspects of method development, including sample dilution requirements, the primary sources of residual host cell DNA, and a summary of the method qualification results.
