1000-P: Efficacy and Safety of Semaglutide 0.5 mg vs. Dulaglutide 1.5 mg Once Weekly in Type 2 Diabetes: A Post Hoc Analysis of SUSTAIN 7 (2019)

Semaglutide and dulaglutide are glucagon-like peptide-1 receptor agonists for the treatment of type 2 diabetes (T2D). In SUSTAIN 7, an international, open-label, parallel group trial, adults with inadequately controlled T2D were randomized (1:1:1:1) to once-weekly subcutaneous semaglutide or dulaglutide at low (0.5 vs. 0.75 mg) or high (1.0 vs. 1.5 mg) doses. Semaglutide provided superior glycemic control and reductions in body weight at both low and high doses. To study doses available in clinical practice, we performed a post hoc analysis of the effects of semaglutide low (0.5 mg) vs. dulaglutide high (1.5 mg) dose at week 40, using statistical methods in published prespecified analyses. Subjects mean age was 56 years, HbA1c 8.2%, diabetes duration 7.4 years; 77% were white. Efficacy data (Table) show similar glycemic control and blood pressure, and greater weight loss, for semaglutide 0.5 mg vs. dulaglutide 1.5 mg. Frequency and severity of adverse events (AEs) were similar for semaglutide and dulaglutide, including gastrointestinal (GI) AEs (nausea: 23% vs. 20%, respectively; vomiting: 10%, each treatment). Premature discontinuation due to GI AEs occurred in 5% of subjects in each arm. In summary, semaglutide 0.5 mg showed similar improvements in glycemic control and greater weight loss vs. dulaglutide 1.5 mg at week 40, while showing similar tolerability in subjects with T2D.
