10:20 am Morning Coffee Break


10:50 am Holistic approach to Comparability


    • What is comparability and what triggers the need for comparability?
    • What is clinical comparability? What is Analytical comparability?
    • Impacts of comparability on your overall program
    • Are there ways to limit comparability risk?
    • How can Resilience help your program?
      • Platform approaches for process and analytical
    • Slowing down to go faster
      • Program or portfolio approach?
      • Are there ways to streamline?


11:20 am Virtual Presentation: A-Cell: Best Practices for the Manufacture of Cell Therapies

  • Josephine Lembong Manager, Science & Industry Affairs, Alliance for Regenerative Medicine


  • Establishing Quality Target Product Profile and Critical Quality Attributes early are critical to managing comparability across products and process changes during development
  • Risk and criticality assessment tools are used throughout product development to establish processing operations, design space, and control strategy to ensure the process delivers a quality product in a reproducible process
  • A comparability plan to introduce manufacturing changes should be developed as early as possible in product development, preferably before a phase 1 trial
  • The acceptability of comparability depends on the knowledge of the product, availability of well-defined CQAs that are informative for product safety and efficacy, and timing of when the major change is introduced in the product development cycle

11:50 am Case Study: Assessing the Type & Magnitude of Change in Order to Develop an Appropriate Comparability Test

  • William Werner Sr. Director Analytical Assay development, Astellas Gene Therapies


  • Addressing comparability dependent on the extent of change, the impact on critical quality attributes and the linkage to implications on safety and efficacy

12:20 pm Analytical to Clinical: Ensuring Analytical Method Validation Supports Clinical Determination


  • How to generate value added data that ensures clinical determinations and endpoint assessments are based on the analysis from a robust analytical method validation
  • Define what method validation really entails and the attributes that are critical to understand
  • Review the controls that are fundamental for clinical determination and the components that support validation methods
  • Reflect on how to apply the Quality By Design principles in practice and provide a roadmap to pathway success

12:50 pm Lunch & Networking

2:19 pm

2:20 pm Quality Attributes and Extended Characterization of Gene Vectors Using Light Scattering

  • John Champagne Senior Applications Scientist and Northeast Regional Manager, Wyatt Technology


  • The new LNP Analysis method enables size-based nucleic acid payload
  • MD-SEC and MD-FFF are essential tools for measuring LNP size, concentration, payload, and product quality

  • Introduce a new workflow for p24 based titer assessment and protein profiling of structural and non-structural proteins
  • Introduce an additional workflow for the size and purity analysis of the lentiviral genome
  • Discuss the use of these workflows to analyze the genome and proteome of lentiviral vector in-process samples

4:20 pm Application of Asymmetric Flow Field-Flow Fractionation coupled to Multi-Angle Light Scattering (A4F-MALS) for the Characterization of AAV Products


  • Development of an A4F-MALS method to evaluate important quality attributes of AAV products, including purity, percent aggregation, capsid particle concentration, and putative empty/full ratio will be discussed
