Health-Related Quality of Life Assessments with Once-Weekly Glucagon-Like Peptide-1 Receptor Agonists in Type 2 Diabetes Mellitus

Type 2 diabetes (T2DM) is associated with significant impairment in health-related quality of life (HRQoL). A patient-centered collaborative approach is recommended to optimize clinical outcomes, including HRQoL, in this patient population. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) provide effective glycemic control and have demonstrated beneficial effects on HRQoL and treatment satisfaction. Available once-weekly GLP-1 RAs may offer enhanced convenience compared with daily GLP-1 RAs and include exenatide extended-release (ER), dulaglutide, and semaglutide. This article reviews the impact of once-weekly GLP-1 RAs on HRQoL and treatment satisfaction in patients with T2DM. Compared with oral antihyperglycemic drugs, insulin, and daily GLP-1 RAs, once-weekly GLP-1 RAs offer benefits with regard to HRQoL and treatment satisfaction. These benefits appear to be largely mediated by relative drug effects on glycemic control, weight, and hypoglycemia. While there was not an overall class benefit of once-weekly GLP-1 RAs compared with daily GLP-1 RAs on HRQoL and treatment satisfaction, results suggested that once-weekly GLP-1 RAs may enhance certain elements of treatment satisfaction and increase willingness to continue treatment. In 2 studies comparing once-weekly GLP-1 RAs with each other, semaglutide produced significantly greater improvement in overall treatment satisfaction compared with exenatide ER but not dulaglutide. Once-weekly GLP-1 RAs represent an effective and convenient treatment option that may potentially increase treatment satisfaction and enhance adherence, contributing to improved health outcomes.
