NC3Rs/EPAA Webinar: Re-evaluating the need for mAb chronic toxicity studies

To support registration of monoclonal antibodies (mAbs) for chronic indications, 6-month toxicity studies have historically been conducted as per ICH S6(R1) guidance. Experience with mAb development has shown a relatively benign and well-understood safety profile for this class, with most toxicity findings anticipated based on pharmacology.

Under a European Partnership for Alternative Approaches to Animal Testing (EPAA) supported and funded project, a consortium of 14 pharmaceutical companies, the Medicines Evaluation Board (MEB) and the NC3Rs conducted a study to evaluate whether a 6-month toxicity study is still necessary to assess the long-term safety of mAbs.

The aim of this joint NC3Rs/EPAA webinar is to provide an overview of the two recent publications from the project, discussing key results and recommendations. In particular, a proposed weight-of-evidence model will be highlighted, with case-studies explaining the potential decision processes.  Additionally, 3Rs opportunities identified within the dataset, including group sizes and use of recovery animals, will be presented.

This webinar is relevant for regulatory and industry scientists working with mAbs and other drug modalities interested in exploring new approaches for chronic toxicity studies and opportunities to apply the 3Rs. There will be a panel discussion at the end of the webinar when audience members will be able to ask questions.

The agenda for the webinar is below:
