Expert Interview with Dr. Eric Bonner

The immunogenecity of biologics is a significant concern, which can affect safety and efficacy. In this interview with Dr. Eric Bonner, we explore recent developments in immunogenecity, highlight key challenges when reviewing immunogenecity, and explore current regulations.

Immunogenecity is the ability of a therapeutic protein to stimulate an immune response, developing anti-drug antibodies to neutralize or bind the offending protein. It is an important assessment required for drug approvals that is measured and characterized. However, with the increase in biologics, how do scientists apply more sensitive and robust techniques and what challenges remain for assessing immunogenecity?

We aim to cover a range of developments, including:

• Techniques utilized to investigate immunogenecity

• Relationships between assay data and clinical outcome

• Regulation and standardization
