Paediatric Extrapolation According to ICH E11A
Who it is for
- This is an Expert Discussion Group with a requirement for participation.
- Experience in pediatric clinical research is required.
- Experience with extrapolation is helpful but not required.
What it covers
Pediatric extrapolation is the practice of using data generated in one population - typically adults or an older pediatric age group - to support conclusions about efficacy, safety, or dosing in a younger or different pediatric population.
One of the key aims of extrapolation is to reduce the need to generate new, dedicated pediatric data without compromising efficacy and safety.
The ICH E11A (2024) Guideline on Pediatric Extrapolation (https://www.ema.europa.eu/en/ich-guideline-e11a-pediatric-extrapolation-scientific-guideline) was implemented by the FDA and the EMA in December 2024 and January 2025, respectively.
It is the first standalone ICH efficacy guideline dedicated specifically to pediatric extrapolation methodology, and it sets out a systematic approach for planning, justifying, and executing extrapolation across a pediatric drug development program.
Two core components require documentation:
- Pediatric Extrapolation Concept
- Pediatric Extrapolation Plan
As the pharmaceutical industry orients itself to this new guideline, this EDG aims to bring together regulatory medical writers working in this area to discuss challenges, exchange ideas, and share practical approaches.
Requirements for participants
- Experience in pediatric clinical research is required.
- Experience with extrapolation is helpful but not required.
