The agency clarifies how FDA determines when a risk evaluation and mitigation strategy is necessary.
FDA published draft guidance on Sept. 20, 2016 clarifying the agency’s factors in determining when a risk evaluation and mitigation strategy (REMS) is necessary. According to the guidance, while routine risk mitigation measures may be sufficient to preserve the benefits of a drug and minimize potential risks, a REMS may be required to ensure the benefits of a drug do in fact outweigh the risks.
FDA may impose elements, such as a medication guide and/or a communication plan, as part of the REMS. FDA designs these elements based on what the agency feels will help reach the goals of a proposed REMS.
A REMS, however, may pose a burden on patients and/or healthcare providers. The agency, therefore, considers the following factors when making a decision on if a REMS is required:
The guidance states, “FDA makes decisions about requiring a REMS as part of a benefit-risk determination for a drug after an evaluation that includes integrated consideration of each of the statutory factors. No single factor, by itself, is determinative as to whether a REMS is necessary to ensure that the benefits of a drug outweigh its risks.”
FDA states in the guidance that the agency takes existing REMS elements into account for other drugs with similar risks. FDA also takes into consideration any REMS elements and tools that may have already been used in clinical trials. “Selection of risk management elements and tools is also informed by any regulatory precedent for addressing similar risks,” the guidance states.
