ICH Patient Preference Guidelines Out for Comment
FDA has published for public comment an International Council for Harmonization draft guideline, General Considerations for Patient Preference Studies E22, with general considerations about the use, design, conduct, analysis, and submission of patient preference studies (PPS) aimed at informing drug development, regulatory submission and evaluation, drug approvals, and maintenance of such approvals. The document focuses on stated preference methods that involve collecting performance data through surveys or interviews where participants are asked to state their choices or acceptable thresholds for trade-offs for specific outcomes or treatment alternatives.
The guideline’s emphasis is on the application of drugs intended for treatment, FDA says, but it also applies to drugs intended for prevention or diagnosis in healthy individuals or prospective patients. The guideline addresses PPS and the value that patients place on characteristics of drugs, it says, and does not focus on patient-reported outcome measures.
Because preference research is a large and evolving field, the guideline contains general considerations and scientific principles rather than detailed technical instructions.
