Pharmaceutical issues during the review of European Marketing Authorisation Applications in Malta*

Abstract The aim of this study was to identify pharmaceutical issues encountered during regulatory review in European Procedures. A database of issues from Day 70 assessment reports of 150 EU procedures was compiled; most procedures were for generics (108). Frequencies of common deficiencies have been calculated and summarised for use of all stakeholders. Out of the 150 procedures reviewed, covering 309 products, a total of 4796 concerns were identified. Of these concerns, 167 were Potential Serious Risks to Public Health, 67 were raised on drug substance and 100 on the drug product. The distribution of total concerns was as follows: 2168 concerns on drug substance and 2584 on drug product. Most concerns raised were on control of drug substance and drug product (834 & 626 for 3.2.S.4 and 3.2.P.5, respectively), followed by concerns on the manufacturing (482 & 564 for 3.2.S.2 and 3.2.P.3, respectively) and stability 147 & 398 for 3.2.S.7 and 3.2.P.8, respectively). In conclusion, the frequencies and trends of identified deficiencies together with their impact were discussed from a regulatory point of view. The main findings indicate that applicants would benefit from following published guidelines so that delays in the registration of medicines could be avoided.
