The International Council on Harmonisation (ICH) announced the adoption of its E2D(R1) guideline, which aims to standardise terminology related to adverse events and streamline procedures and timelines for collecting and reporting post-approval safety data for medicinal products. Further to public consultation in February 2024 which resulted in only minor revisions to the draft guideline, the revisions update the original guideline adopted in 2003 to account for new sources of post-approval safety information such as through social media, market research programs, and patient support and assistance programs. The revised guideline includes: clarification and standardisation of key terms such as adverse events, adverse drug reactions, serious adverse events/adverse drug reactions, and unexpected adverse events/adverse drug reactions; reporting timeframes, such as that ICSRs that fulfil regional or local criteria for expedited reporting should be submitted no later than 15 calendar days after day zero; new qualifier language in Section 2.2 regarding the minimum criteria for Individual Case Safety Reports (ICSRs); new language that clarifies the definition of a digital platform specifying that 'digital platforms include, but are not limited to, social media, websites, internet forums, chat rooms, mobile health technologies, and software applications (apps)'; and another example of an organized data collection system (ODCS) to include 'an activity where an MAH monitors and analyses user communications on a social media site, often referred to as social listening or digital listening, is an example of ODCS'.
