Good Lay Summary Practice Recommendations are now published in EudraLex.

Wednesday, October 27, 2021. 
Good Lay Summary Practice (GLSP) Recommendations were published on 4th October 2021 in EudraLex Volume 10. It was adopted by the Expert Group on Clinical Trials (CTEG, a working group of the European Commission consisting of representatives from Ethics Committees and National Competent Authorities and EMA) and was developed in cooperation with the Roadmap Initiative to Good Lay Summary Practice Group.

In March 2019, the EFGCP, in collaboration with EFPIA, established an international multi-stakeholder group to identify best practices for the delivery of a fit-for-purpose Lay Language Summary (LS) of clinical study results, with the intention to build on existing European Commission guidance issued in 2017 and on global sponsors’ experience so far (TransCelerate and MRCT). To this effect, the LS working group consisting of experts from 60+ academia, pharmaceutical industry, patient organisations, and not-for-profit organisations set up the Roadmap Initiative to Good Lay Summary Practice (GLSP). Its objective was to enable a framework for the planning, development, translation, and dissemination of LSs of clinical trial results as required by the 2014 EU Clinical Trials Regulation (CTR No 536/2014).

To create an environment that is favourable to conducting clinical trials in the EU, with the highest standards of safety for participants and increased transparency of study information, the Regulation requires, among other obligations, to publish on the Clinical Trial Information System (CTIS) information on the authorisation, conduct and results of each clinical trial with a medicinal product carried out in the EU. As of February 2022, the European Medicines Agency (EMA) will make information stored in CTIS publicly available since CTIS will be the single entry point for submitting clinical trial information in the EU.

The Roadmap Initiative to GLSP Group has continuously worked diligently over 2.5 years and established relationship with the EU Commission’s CTEG to deliver on its roadmap. Building on the experience of public and private sponsors beyond Europe, and with patient involvement and the efficient support of the CTEG, a 85-page comprehensive guidance including a quick guide, was issued to help sponsors from the planning and scoping stage, through the development process, translation and to the final dissemination stage (see Figure 1); the ultimate goal being “to enable all sponsors to generate and disseminate objective and understandable information on clinical trial results,” for trial participants and the general public.

The guidance acknowledges the challenges such as patient involvement, resources, and LS translations, which may vary depending on whether the sponsor is from academia or industry. Since there is still limited experience to reporting paediatric trial results the GLSP, while recognising that these studies need special approaches for LS generation, provides preliminary recommendations with the hope to have them completed in the future, with experienced gained.

In line with Annex V of the CTR, the GLSP provides details on how to best summarise the key trial results in a LS and advises sponsors to establish a standard operating procedure and a LS template. In addition to patients’ involvement and identifying a drafting/delivering team with the necessary skills and expertise, recommendations also focus on how to report complex trials and safety results and select appropriate layouts and graphics. All these if appropriately displayed, should contribute to easy readability and increased understanding of the content of the LS. Although the EU CTR does not require LS’ translation(s), the GLSP recommends, at a minimum, to provide the LS “in the local language(s) of each of the countries where the trial took place”, which is already current practice among industry sponsors. Finally, dissemination beyond inclusion into CTIS can be considered, e.g., through email or the sponsor’s website, or printed copies of the LS provided to the investigator.

From now on, the Roadmap Initiative to GLSP Group is considering actions that will help further dissemination and implementation of its recommendations, e.g., through webinars, workshops, and trainings. Stay tuned for further communication!
