On 11 April 2025, the new ICH Q1 Draft Guideline “Stability Testing of Drug Substances and Drug Products” was published, marking a comprehensive revision and consolidation of the former ICH Q1A–F and Q5C Guidelines. Against this background, the ECA is offering a compact, 3-hour Live Online Training on 18 June 2025. The training is designed to provide participants with a clear overview of changes, new aspects and interpretations of the upcoming regulatory expectations with respect to the stability strategy.
