EVMS has an institutional license to MedDRA (Medical Dictionary for Regulatory Activities), a clinically validated international medical terminology used by regulatory authorities, including the FDA. It is also used by industry, academics, health professionals and other organizations to communicate medical information. 

MedDRA is a standardized dictionary of terms used to describe adverse events of drugs and therapeutic biologic products in animal and clinical trials. Medical terms are linked to capture logical relationships, making it possible to create meaningful summaries and conduct analyses.
