For the FDA Pilot COA Compendium to fulfill its purpose of fostering PFDD, it needs fine-tuning to reflect today's standards, improving transparency and facilitating clear identification of included measures so that the level of patient engagement, among other factors, can be properly assessed. Suggested improvements include identifying clinical trials that correspond to the COA Compendium's use in drug development; more clearly identifying which measure is referred to; and including only those measures that already qualified or undergoing qualification.

Introduction:Over the past decade, health technology assessment (HTA) agencies have become interested in improving the patient-centeredness of their assessments. A common approach has been to prioritize patient-reported outcomes (PROs), often describing PROs as patient-relevant or patient-oriented. However, it is often unclear whether and to what degree PRO measures (PROMs) truly reflect what is important to patients. This review examined the pedigree of a sample of measures used as primary or secondary endpoints in trials and discussed in Food and Drug Administration (FDA) approved product labels between 2003 and 2014.Methods:We examined all 26 PROs included in chapters 1 (Office of Microbial Products) and 2 (Office of Drug Evaluation I) of the FDA's Pilot Clinical Outcome Assessment (COA) Compendium. Three reviewers independently searched PubMed and Google to identify publications or other relevant materials related to method and stage of measure development where patient engagement took place.Results:Among 26 evaluated PROMs, we were unable to locate any information on development or validation for 12 (patient diary=9; rating scale=3). Among the remaining 14 PROMs, 5 did not include any evidence of patient engagement (questionnaire=1; patient diary=2; rating scale=2); 3 engaged patients during concept elicitation or psychometric validation only (disease-specific questionnaires=3); and 6 engaged patients during both concept elicitation and cognitive interviewing (disease-specific questionnaires=6). PROMs either previously qualified or submitted for qualification by FDA were more likely to include patient engagement.Conclusions:PROs can provide patient-centered data useful for HTA; however, patient-reported information is not inherently patient-centered. This study found that only a minority of sampled PROMs engaged patients during both concept elicitation and cognitive interviewing. To facilitate patient-centered HTA, manufacturers should ensure that PROMs incorporated into clinical trials measure concepts important to patients. Similarly, HTAs should request data on development and validation of all outcome measures incorporated into trials.
