Workshop Session I: Nuts and Bolts of Bioassays
Apr 18, 2023 10:00am ‐ Apr 18, 2023 11:45am
Identification: 64153
Bioassays are one of the more complex assays used to support therapeutic product development. As such, the practical elements of bioassays (the “nuts and bolts”) can also be complex. These elements can range from the critical reagents selected for use in the bioassay (e.g.-cell line(s), recombinant proteins, serum) to assay formats (e.g.-dual cell-based cytotoxicity assays, single cell-based reporter gene assays, non cell-based binding assays), to the data analysis model selected (e.g.-4 -parameter logistic curve fit, 5-parameter curve fit). The sustainability of these “nuts and bolts” is vital to establishing and maintaining bioassays over the lifecycle of a therapeutic product. This session will focus on different practical elements of bioassays and their impact on establishing desired method performance.

Workshop Session II: Bioassays for Vaccines and Anti-Infective Therapies
Apr 18, 2023 2:30pm ‐ Apr 18, 2023 3:50pm
Identification: 60427
Development of Potency Assays for vaccines and anti-infective biologics can present a unique set of challenges. As the human immune system is complex, frequently the full mechanism of protection is not known, so best judgment must be used to select a mechanism for a representative potency assay. This is particularly true for novel vaccine technology (e.g., mRNA, nanoparticles) and pandemic response, both of which have occurred in the last few years. The talks in this session will provide insight into the approaches of multiple teams to address these challenges, including use of modern potency techniques where feasible.
Key questions to address:
1. How to select the assay format: e.g. in vitro vs. in vivo?
2. What is the minimum requirement for correlation of in vitro and in vivo data?
3. For genetic vaccines, can in vitro expression be assumed to reflect immunogenicity?
4. For new vaccine technology, applied in an established space, such as influenza, how best to introduce modern potency assay techniques?
5. Given the challenge of strain updates and multivalent strategies, what approaches can be taken to “platform” release methods so that assays for new strains can be quickly validated?
6. What lessons from efforts undertaken to rapidly respond to the pandemic may be applied to other programs?

Workshop Session III: Bioassays for Cell and Gene Therapeutics

Identification: 60468
Cell and Gene Therapies (CGT) are transforming not just how humans treat genetic and intractable diseases but are altering the entire pharmaceutical ecosystem. CGT are rapidly becoming established as the new wave of biological therapeutics with autologous or allogeneic engineered cells as the active therapeutic (Cell Therapy), or the gene delivery system (Gene Therapy; e.g., LNP’s, AAV’s, etc.). More than 18 CTx or GTx products were approved by US FDA in 2020. Around 990 companies are engaged in R&D and commercialization of next-generation CGT. In short, CGT is in the process of becoming a mainstream.
Compared to other biological such as mAbs, BsAbs and proteins, CGT therapeutics are much more complex both physically and biologically, and present specific challenges for developing in vitro potency assays due to their complex mechanisms of action, complicated manufacturing processes and variable critical quality attributes (CQAs). This session will explore considerations and case studies demonstrating strategies of dealing with these biological complexities throughout the product life cycle.

Workshop Session IV: Process Improvements/Innovation in Bioassays
Apr 19, 2023 1:15pm ‐ Apr 19, 2023 3:00pm
Identification: 60472
There are several drivers behind the need for process improvements and innovation in the CMC bioassay space. Most organizations experience a constant pressure to reduce cost, increase throughput, and be more efficient. Sometimes, there is a need or a strong desire to improve a bioassay by making it more accurate, precise, or robust. And in some cases, bioassay innovation is driven by the drug itself: for example, by the need to adequately capture increasingly complex modes of action in simple model systems, characterize specific attributes, or the requirement to distinguish the effects of different drug molecules. At the same time, improvements and innovations need to be designed and executed so as to ensure data integrity, using instrumentation and procedures that are transferrable to a QC testing lab. Navigating these different needs and constraints can be challenging. In this session, we will focus on how different organizations have approached and balanced these challenges.
