Regulatory authorities are encouraging the submission of patient experience data, including patient preference information (PPI). We provide an overview of PPI and the use of PPI in the regulatory setting. Many PP health studies recognise the usefulness of PPI, however, challenges remain in defining how and when to incorporate it in the regulatory process. While the use of PPI in regulatory decisions has been limited, regulatory agencies, sponsors, and researchers continue to work together to develop guidelines to integrate PPI into approval decisions.
