Assessing the Regulatory Landscape for Analytical Development of ADCs
3:00 pm Roundtable Discussion
Synopsis
As ADCs become more complex in structure and scientists improve their understanding of the effect of structure on its function, regulatory bodies are demanding an increasing abundance of evidence to show safety, stability, efficacy and consistency of each drug.
Understanding the key pieces of information regarding acceptance criteria, critical quality attributes and methodologies from a regulatory perspective is therefore pivotal to prevent delays in submission and clinical development.
Topics to be discussed include:
- With more advanced analytics more aspects of molecules can be measured – what are the key aspects which need characterization and should be included on release or control strategy?
- Are specifications required for all numerical controls for all ADC CQAs?
- Examining what information you must provide in the regulatory dossier regarding the reference?
- What are the critical pieces of information to include in a briefing book and what can be left out?
