Immunogenicity assessment helps drug developers understand the possible immune responses that can occur when humans are exposed to a potential therapeutic protein. Recently, the FDA has updated its guidance for immunogenicity risk assessment for developing and validating assays for anti-drug antibody (ADA). In this webinar, we will provide an overview of the significant changes, discuss implications for your IND- and BLA-enabling studies and review the testing that is necessary for regulatory submissions.
What’s Different in 2019 FDA Guidance for Immunogenicity Risk Assessment?
The guidance further clarifies FDA’s recommendation when compared to the previous guidelines published in 2016. Many aspects of this guidance were revised, but the significant revisions focus on the following areas:
- Risk assessment
- Statistical approaches to ascertain cut point
- Removal of long-term stability requirement
- Minimal required dilution
- Positive control antibodies
- Development of assays to measure neutralizing antibodies
- Strategies for managing pre-existing antibodies
- Updates in documentation requirements
