Comparing regulatory guidance on risk minimization/mitigation and the Reporting recommendation Intended for pharmaceutical Risk Minimization Evaluation Studies checklist.

The latest country-specific regulatory guidance for assessing effectiveness of risk minimization measures (RMM) strategies was identified across five continents-Africa (Egypt, South Africa), Asia (Australia, China, Japan, South Korea, Singapore), Europe (EU-27, United Kingdom), North America (Unites States, Canada) and South America (Brazil)-and compared to the Reporting recommendation Intended for pharmaceutical Risk Minimization Evaluation Studies (RIMES) checklist, developed to assess the quality of effectiveness evaluations and endorsed by the European Network of Centres for Pharmacoepidemiology and Pharmacovigilance (ENCePP). RIMES checklist items address study hypothesis, participants, measures, statistical analysis and results. European Medical Agency (EMA) and Food and Drug Administration (FDA) guidance only partially aligned with RIMES, primarily for measures and results. In the absence of country-specific guidance, most countries recommended following EMA or FDA guidelines; Japan and South Africa mentioned the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH E2E) guideline; Brazil and China had no guidance/recommendations. Worldwide, there was a lack of RMM-specific guidance and, when guidance existed, they were not harmonized, and alignment with the RIMES checklist was limited.
