Efficacy and Tolerability of Exenatide Once Weekly Versus Sitagliptin in Patients With Type 2 Diabetes Mellitus: A Retrospective Analysis of Pooled Clinical Trial Data

AbstractAim: Therapies for type 2 diabetes mellitus that leverage the glucagon-like peptide-1 (GLP-1) receptor signaling pathway have been shown to reduce rates of hyperglycemia and have beneficial effects on body weight. This post hoc analysis compared the effects of 2 GLP-1 receptor-based therapies, exenatide once weekly (EQW), a GLP-1 receptor agonist, and sitagliptin (sita), a dipeptidyl peptidase-4 inhibitor, on glucose control across the range of baseline glycated hemoglobin (HbA1c) levels specified in the American Association of Clinical Endocrinologists and American College of Endocrinology treatment algorithm. Materials and Methods: Data from patients treated with either EQW or sita for 26 weeks in 2 randomized, double-blind, comparator-controlled clinical trials were pooled and analyzed. Glycemic endpoints and cardiovascular risk factors were evaluated in subgroups and the overall population. Results: Analysis included 737 patients on background therapies of diet and exercise and/or metformin. W...
