Lay Summaries of Clinical Study Results: An Overview

The European Union Clinical Trials Regulation (EU CTR) 536/2014 includes a requirement for the submission of lay summaries. Study participants, advocacy groups, and, to a lesser extent, the general public have called for greater transparency in their quest for information on clinical studies. As a complement to other forms of clinical study disclosure such as registry postings and scientific publications, lay summaries may aid in the transparency of a sponsor's clinical study results, thereby promoting trust, partnership, and patient engagement throughout the clinical study process. The data transparency field is changing rapidly; therefore, data owners should strive to stay abreast of the changes and deliver meaningful tools to their study participants and the public. Points to consider when developing lay summaries of clinical study results include regulatory drivers, the target audience, communication of complex data in a lay manner, and efficient processes for the development of lay summaries within one's company.
