Perspectives on Patient-Reported Outcome Data After Treatment Discontinuation in Cancer Clinical Trials

Objectives: Patient-reported outcome (PRO) data are critical in understanding treatments from the patient perspective in cancer clinical trials. The potential benefits and methodological approaches to the collection of PRO data after treatment discontinuation (eg, because of progressive disease or unacceptable drug toxicity) are less clear. The purpose of this article is to describe the Food and Drug Administration's Oncology Center of Excellence and the Critical Path Institute cosponsored 2 hour virtual roundtable, held in 2020, to discuss this specific issue.Methods: We summarize key points from this discussion with 16 stakeholders representing academia, clinical practice, patients, international regulatory agencies, health technology assessment bodies/payers, industry, and PRO instrument development.Results: Stakeholders recognized that any PRO data collection after treatment discontinuation should have clearly defined objectives to ensure that data can be analyzed and reported.Conclusions: Data collection after discontinuation without a justification for its use wastes patients' time and effort and is unethical.
