EMA and FDA have published in joint an article entitled “A comparison of EMA and FDA decisions for new drug marketing applications 2014-2016: concordance, discordance and why”. Most of information were sourced from EMA´s European Public Assessment Reports (EPARs) and FDA reviews. The study consisted of comparing decisions on 107 new medicine applications at the EMA and FDA between 2014 and 2016.
The result of the analysis is the EMA and FDA alignment in more than 90% of marketing authorization decisions for new medicines. The most common reasons for discordance were differences in conclusions about efficacy and differences in clinical data submitted in support of an application.
