FDA Announces Availability of a Public Docket, “Exposure-Response Analysis in Drug Development and Regulatory Decision Making; Request for Comments”
On April 6, 2018, the U.S. Food and Drug Administration (FDA) announced the availability of a public docket entitled “Exposure-Response Analysis in Drug Development and Regulatory Decision Making; Request for Comments” to give interested parties an opportunity to identify areas of scientific policy that may need further clarity or elaboration, as well as any obstacles preventing use of exposure-response analyses in drug development and regulatory review.
The Prescription Drug User Fee Act of 2017 (PDUFA VI), part of the FDA Reauthorization Act of 2017 (FDARA), highlights the goal of advancing model-informed drug development (MIDD). Exposure-response analysis is a MIDD strategy that has been used in drug development and regulatory decision making. On May 6, 2003, FDA issued a guidance for industry titled “Exposure-Response Relationships – Study Design, Data Analysis, and Regulatory Applications” (available athttps://www.fda.gov/downloads/
Interested persons are invited to provide detailed information and comments on the use of exposure-response analysis in drug development and regulatory review. FDA is particularly interested in responses to the following questions and will consider all information and comments submitted:
- In general, are there any aspects of the 2003 guidance for industry titled “Exposure-Response Relationships--Study Design, Data Analysis, and Regulatory Applications” that merit further elaboration? Additionally, are there any new topic areas that should be addressed?
- What are best practices for conducting exposure-response analysis that can be generally applied across development programs and regulatory submissions? Input on best practices can include any of the following topic areas:
- Planning and design (e.g., data considerations, assumption setting)
- Analytical approaches (e.g., exposure and response metrics, choice and inclusion of predictors, methods for addressing confounding factors)
- Model evaluation and qualification (e.g., goodness-of-fit, assessment of model risk, impact on regulatory decisions)
- Communication of results and impact on subsequent drug development or regulatory decisions
- What attributes of an exposure-response analysis are critical to effectively inform a drug development or regulatory decision? Additionally, what are the main obstacles preventing widespread acceptance of exposure-response analyses?
- During which stages of drug development would it be most productive to interact with the FDA regarding exposure-response analysis planning? What type of feedback would be useful to inform exposure-response analyses and to reduce uncertainty in regulatory acceptance?
