Guidance for Industry Patient-Reported Outcome Measures: Use in Medical Product Development to Support Labeling Claims
This guidance describes how the Food and Drug Administration (FDA) reviews and evaluates existing, modified, or newly created patient-reported outcome (PRO) instruments used to support claims in approved medical product labeling.2 A PRO instrument (i.e., a questionnaire plus the information and documentation that support its use) is a means to capture PRO data used to measure treatment benefit or risk in medical product clinical trials. This guidance does not address the use of PRO instruments for purposes beyond evaluation of claims made about a medical product in labeling. This guidance also does not address disease-specific issues. Guidance on clinical trial endpoints for specific diseases can be found on various FDA Web sites.3 By explicitly addressing the review issues identified in this guidance, sponsors can increase the efficiency of their discussions with the FDA during the medical product development process, streamline the FDA’s review of PRO instrument adequacy and resultant PRO data collected during a clinical trial, and provide optimal information about the patient perspective for use in making conclusions about treatment effect at the time of medical product approval. PRO instrument development is an iterative process and we recognize there is no single correct way to develop a PRO instrument. Different strategies and methods can be used to address FDA review issues.
