ICH E11A: Final version published
In August, the final “ICH E11A Guideline on pediatric extrapolation” was published on the ICH website in the “efficacy guidelines” section. As already reported in "Clinical Trials - ICH E11A on Pediatric Extrapolation", this guideline is intended to promote the international harmonization of methods and strategies for the inclusion of pediatric extrapolation in drug development plans and to accelerate access to new medicines for pediatric patients worldwide. It is seen as complementary to the guideline “ADDENDUM TO ICH E11: CLINICAL INVESTIGATION OF MEDICINAL PRODUCTS IN THE PEDIATRIC POPULATION E11 (R1)” and is expected to become effective in January 2025.
The new guideline consists of the following chapters:
