More Patient-Reported Outcome Bias Study Needed: FDA
FDA oncology researchers say that patient-reported outcome (PRO) assessments can contribute important information about the patient experience during treatment with anticancer products and use of such assessments is likely to increase. Writing in JAMA Oncology, the researchers say randomized oncology trials are increasingly open-label, and the accelerated approval pathway is frequently sought for oncology products based on single-arm trials, which can lead to bias in the patient-reported outcomes.
“Rigorous characterization of symptoms and function using PRO measures can complement current trial outcomes, and this information may be incorporated into decision-making by regulators, payers, patients, and families alike,” the researchers say. “It is important to acknowledge that this will take place in a context that has potential for bias. Carefully targeted research that improves our understanding of the existence and magnitude of this bias is important and can inform thoughtful analysis and accurate interpretation of this data.”
