Assessment Plan

This webpage provides REMS assessment plan measures, metrics, and indicators for drug and biological products with a REMS. The REMS assessment plan measures, metrics, and indicators are part of the overall REMS assessment plan used by FDA to evaluate the performance of a REMS and are included in FDA approval letters. The current REMS assessment plan measures, metrics, and indicators are extracted from regulatory letters that contain REMS information, including FDA approval letters, and posted here as they become available.
