The importance of patient-reported outcomes in type 2 diabetes: insight from the PIONEER program with oral semaglutide

Patient-reported outcomes (PROs), including treatment satisfaction, patient well-being, and quality of life, are becoming increasingly important contributors to treatment decisions in clinical practice and the evaluation of health care services. PROs have been included in a number of clinical trials in patients with type 2 diabetes (T2D), including those investigating glucagon-like peptide-1 receptor agonists (GLP-1RAs). The first oral GLP-1RA, oral semaglutide, was approved in the United States in 2019. Four PROs were included in the PIONEER clinical study program that evaluated oral semaglutide in patients with T2D across the full diabetes disease spectrum. PRO findings in the PIONEER studies were generally similar for oral semaglutide and comparators, with some exceptions. Improvements in a number of the 36-item Short Form Survey domains were observed for oral semaglutide versus placebo, including general health, bodily pain, physical component summary, social functioning, and mental health. For general health and social functioning, differences significantly favored oral semaglutide versus empagliflozin, whereas role-physical and the physical component summary significantly favored empagliflozin compared with oral semaglutide. The Diabetes Treatment Satisfaction Questionnaire findings indicated that oral semaglutide improved feelings of unacceptably high blood sugars versus placebo (in PIONEER 4, 5, and 8) and sitagliptin (in PIONEER 7). Significant improvements in craving control and craving for savory were observed with oral semaglutide versus empagliflozin in the Control of Eating Questionnaire (in PIONEER 2). These data provide valuable information that can facilitate a patient-centered approach and guide decision-making in managed care to optimize each patient's treatment experience.
