The advancement in technologies and innovative thinking are profoundly changing biopharmaceutical drug production industry holistically, giving rise to “the factory of the future.” What will the factory of the future with respect to its structure, technologies, processes, and drug product delivery to the patient be? What enablers will manufacturers need in terms of strategy, leadership, employee skills, IT/OT infrastructure, regulatory oversight, and suppliers to make this a reality?

The factory of the future is an innovation vision on how manufacturers should enhance production by transforming manufacturing in three dimensions: plant structure, plant digitization, and plant processes.

Having a holistic vision of the process

Designing and implementing a flexible framework

Evaluating and implementing proper technology and skill

Emphasizing safety, quality, purity, efficacy and regulatory mandates

The bottom line – delivering ROI

The Factory of the Future

Defining limits for analytical method outputs is a central element of a control strategy. Traditional approaches usually focus on ensuring process consistency, while in more advanced approaches the understanding of structural-function relationships are utilized. This enables definition of patient centric limits that focus on controlling the impact of CQAs on product efficacy and patient safety. In certain cases, those limits and can be defined independent from a specific analytical method and where indicated can extend beyond a therapy specific clinical history. Process consistency control and change management are an integral part of the patient-centric specification and risk-based control strategy approach. The presentation will provide some practical examples for the definition of patient-centric specifications and process consistency control.

Defining Patient-Centric Specification in a Risk-Based Control System

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 the 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) 2023 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 use and chemical toxicological information to consider from the U.S. FDA 2023 guidance and ISO documents when estimating chemical toxicological risk will be covered, such as: approaches for characterizing the applicable chemical specific harm(s), 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.

Full title: Established Conditions in Analytical Procedure: Overview, Regulatory Examples and an FDA Laboratory Study

Established conditions (ECs) are manufacturing and control elements considered necessary to assure product quality (e.g., ECs in manufacturing process) and to help assure method performance (e.g., ECs in analytical procedures). ECs in analytical procedures help to maintain reliable results that can ensure the efficient product control strategy during the product life cycle. Changing ECs in analytical procedures may necessitate a certain level of regulatory activity and the level of regulatory activity can be different depending on the strategy defining ECs and the extent of changes. The presentation will first provide a high-level overview of harmonized scientific risk-based approaches for identifying ECs and determining the corresponding reporting categories based on scientific principles described in ICH Q12 and Q14 guidelines. Then, two regulatory examples involving ECs in analytical procedures will be discussed. It is noteworthy mentioning that both parameter and performance-based ECs in an analytical procedure are defined in these two examples. The last part of the presentation will be an FDA laboratory study on a mass spectrometry method for a recently identified NDSRI (Nitrosamine drug substance-related impurity). In this case study, analytical variables and method robustness were investigated according to recommendations from the ICH Q2R2 (draft) Guideline. Based on the impact of each variable on method performance, categorical and numerical ECs were proposed.

Full title: Fully Continuous Purification Platform Using Nanoparticles With Ligands and Ultrafiltration

We present on a truly continuous purification technique with potential to reduce costs-of-goods for mAbs, over conventional chromatography-based separations.

We demonstrate the development and proof-of-concept application of a self-assembling affinity nanoparticle to enable affinity ultrafiltration of mAb from an impure mixture.

This technique leverages counter current flow ultrafiltration, concentration gradients between feed and product, in a series of filters representing the phases of the process. Impurity clearance can remain high while minimizing overall buffer consumption and consequently PMI for water.

Overall, these data represent an early advancement toward the development of a truly continuous, counter-current, and column-free method to capture and purify mAb without expensive conjugated resins. We envision further expansion of commercially available nanoparticles towards modality and application specific designs to enable PMI savings across therapeutic areas, delivering lower cost medicines to patients.

Full title: Analytical Assessment of Leachables in Biological Drug Products: FDA Approach and Experience in Reviewing Information

Biological drug products (biologicals; such as therapeutic proteins, vaccine-, gene-, and cell therapy-based) are produced via multi-step processes involving multiple materials contacting intermediates and sourcing numerous leachables into final drug products (DP). Such steps involve (i) purification of intermediates using chromatography, centrifuging, dialysis, filtering, and filling in final container closure system, etc., (ii) shelf-life storage and (iii) in-use hold of DP. The respective contact materials involve chromatography resins, filtering/dialysis membranes, tubing, collecting bags/tanks, gaskets, valves, final container closure systems, etc. By these, the assessment of leachables risk in biologics is the most challenging compared to other types of DPs. However, current guidances are generally focused on assessment of the leachables only from single manufacturing components, scored to be high-risk for leachables, and by this, underestimate other components scored to have the lower risk. Following these directions, manufacturers typically perform the assessments only for the high-risk components and by this, underestimate the contribution of other materials to the overall (cumulative) leachables profile in final DP. Other typical issues involve (i) non-validation of analytical methods, resulting in ambiguity in Analytical Uncertainty Factor (AUF) used for calculation of the Analytical Evaluation Threshold (AET; reporting limit in an assay), (ii) missing the assessment of elemental (ionic) leachables, or (iii) incorrect leachables study design; altogether also resulting in potential underestimation of the leachables risk. These issues usually cause multiple back-and-forth communications between the FDA and Sponsor during the applications’ (BLAs and supplements) review, typically ending up with post-marketing requirements.

Following the rapid and successful deployment of mRNA vaccines during the COVID-19 pandemic, over 150 mRNA vaccines are in development, with further therapeutic applications in oncology, cardiovascular and genetic diseases and forecasts predict a high level of growth in products using this drug manufacturing platform. USP engaged with stakeholders in government, drug development, pharmaceutical companies and other experts to build consensus on relevant quality attributes for mRNA-based products and appropriate analytical methods. As part of this effort, USP worked with vaccine experts to generate draft guidelines (Analytical Procedures for mRNA Vaccine Quality) and solicited feedback from stakeholders to update and evolve the guidelines. This presentation will provide an overview of USP updated guidelines and plans for further assessment and qualification of analytical methods presented therein. Physical, chemical, and structural elements of drug substance and drug product and how they relate to product quality attributes will also be discussed.

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.

Full title: A Systematic approach to define operating space and MRT for continuous manufacturing ER tablets: Opportunities and Challenges

Presented by Ahmed Zidan, Senior Staff Fellow (Pharmacologist) Center for Drug Evaluation and Research at FDA, Owen Rehrauer, President of Sentronic US Corp and Rodolfo J. Romañach, Ph.D. Center for Structured Organic Particulate Systems (C-SOPS) at the University of Puerto Rico

Twin-screw wet granulation is an emerging continuous manufacturing (CM) technology for solid oral dosage forms. Compared to batch operation, this technology offers several advantages including reduced processing time, uniform granule size distribution and shape, and real time process control. Continuous granulation process has been successfully employed for commercial manufacture of IR tablets. However, the high polymer content in the ER formulations has poised challenges by narrowing the design space of screw configuration and operating parameters. This design space defines the flow dynamics within the barrel and plays a crucial role in determining the granule properties. This work pursues a systematic approach for defining the optimum operating space and mean residence time (MRT) through understanding the interaction effects of the screw design and processing parameters on the critical characteristics of granules and tablets. The study identified further the opportunities and challenges of using CM granulation for manufacturing of ER formulations containing high load of swellable polymers.

This presentation will showcase a systematic approach for optimizing the operating parameters and process understanding of a twin-screw granulation to manufacture ER tablets. Examples of failure modes will be discussed, along with the implementation of quality-by-design coupled with PAT tools to monitor the critical quality attributes of granules.

Full title: Current State of PAT Applications for a Reliable and Effective PCM Equipment Operation

PAT is an integral part of every Pharmaceutical Continuous Manufacturing (PCM) control strategy. On the other hand, PAT sensors can cause equipment and process inefficiencies due to the complex nature of those instruments. Sensor technology, data volume, sensor maintenance or the interface to the process contribute to operational complexity.

Nonetheless, PAT is required to measure Critical to Quality product Attributes (CQA), on-line or at-line and is enabling Real Time Release strategies. Furthermore, PAT sensors are also used during process and predictive model development, CQA monitoring, diverting Out of Specification (OOS) material and thus are essential for Real time Release testing applications.

Consequently, the selection of PAT applications is a critical step in every PCM business case assessment and during the entire engineering phase of a PCM system. This presentation will provide an overview of commonly used PAT sensor technologies and their selection criteria. Furthermore, it will revisit process design criteria for the optimal positioning of those sensors within the given process flow.

The overall control strategy defines what level of PAT implementation is necessary to run a successful continuous operation. All examples will be supported by real world PAT applications in operating PCM installations. 

Finally, this presentation should provide confidence in available PAT technologies. Innovation will aim for new even more sophisticated sensor technologies and new analytical software tools, but today PCM drug substances and drug product applications are covered and allow lead users to achieve the expected Overall Equipment Effectiveness (OEE) and required Net Present Value (NPV).

Full title: Leachable Risk Assessment Approaches: A Comparison of USP <665>,Biophorum, and Other Methods For Assessing Leachable Risk In Biopharmaceutical Manufacturing Systems

There is currently no agreement on a format for a leachable risk assessment approach when applied to a biopharmaceutical manufacturing system. USP and Biophorum have published some guidelines, however both guidelines have (in the opinion of this speaker) some gaps and flaws. This webinar will provide review of the USP and Biophorum guidance and suggest an alternative approach, which seeks to address these gaps. The approach providing both a consideration of leachable risk in terms of both severity of harm and probability of harm, and its associated uncertainty as a result of a biopharmaceutical manufacturing process and its effect on patient safety.

The approach outlined borrows heavily from principles outlined in ICH Q9 and has been presented in part through ELSIE’s whitepapers published to their website. Its key recommendations are to establish a process whereby the leachable risk is clearly identified, followed by a scoring of the risk through a risk analysis then a risk evaluation against a pre-agreed risk matrix that will output a clear decision on whether further risk control is required and the risk is either accepted or needs reduction. Subsequent study design and requirement is thus based on these principles, rather than a pre-stipulated design.

It is a regulatory requirement (ICH Q5A Revision 2) to demonstrate viral safety of biotechnology product derived from in vitro cell culture, including viral-vector derived products like recombinant Adeno-Associated virus used as a delivery medium for gene therapy products. Viral clearance in gene therapy product poses different challenges from the other non-viral biotechnology product in the viral removal strategies. In this webinar, we will present a case study with a clinically relevant AAV8 downstream process:
1 The rationale of the study design: the choices of virus panel, surrogate and the unit operation for demonstrating viral clearance.
2 Present the clearance achieved in a scaled down model of the process

Full title: Validation of Test Result Equivalence for Alternative BET assays, Including Recombinant Methods

Presented by Karen Zink McCullough, Owner, Principal Consultant at MMI Associates, John Duguid, Executive Director, Research & Development at Vericel Corporation, Steven Walfish, Principal Consultant at Statistical Outsourcing Services and Allen L. Burgenson, Global Subject Matter Expert, Testing Solutions at Lonza

Both FDA’s 2012 Guidance for Industry and USP <1223> specifically use the term, “equivalence” as a requirement for validating an alternative test. Traditional methods, such as the Limulus amebocyte lysate (LAL) assay, are widely accepted and have a proven record of assuring parenteral drug and device safety, but they have limitations, including reagent variability and sustainability concerns. As a result, new methods using a number of innovative platforms, including recombinant technology (rFC and rCR), have emerged. The concept of test result equivalence bridges the gap between old and new technologies, offering cost-effective, environmentally friendly, and reproducible means of endotoxins detection, advancing the industry's ability to ensure continued product quality and patient safety.  This webinar will explore the concepts of equivalence, comparability, and statistical methods used to evaluate them.

Full title: Evaluating Analytical Strategies to Quantify Capsid Titre: Towards a Platform-Method Approach to Accelerate AAV Drug Product Development

Traditional capsid titre methods rely on ELISA which commonly suffers from long turnaround times, low throughput, and large volume sample requirements. This limits the application of ELISA-based methods to routine analysis, thus requiring development of alternative high-throughput (HTP) capsid titre methods. We have performed a comprehensive assessment on currently available orthogonal capsid titre methods using multiple serotypes at concentration range relevant in IND-enabling preclinical and first-in-human (FIH) clinical studies.
