Despite treatment with oral antidiabetic drugs (OADs), achieving effective glycaemic control in type 2 diabetes (T2D) remains a challenge. The objective of this post hoc analysis of data from the SUSTAIN 2, 3, 4 and 10 active-controlled trials was to assess the efficacy and safety of the once-weekly glucagon-like peptide 1 receptor agonist (GLP-1RA) semaglutide in patients on background treatment with metformin (MET), with or without a sulphonylurea (SU).


Data from the randomised phase 3 trials SUSTAIN 2, 3, 4 and 10 for subjects who received background MET alone or MET + SU were analysed. Change from baseline in HbA1c and body weight at the end of treatment visit (week 30 in SUSTAIN 4 and 10, week 56 in SUSTAIN 2 and 3), and rates of hypoglycaemia and adverse events leading to premature treatment discontinuation were assessed.


In total, 3411 subjects were included in the full analysis set (3410 in the safety analysis set). Across the four trials, semaglutide significantly reduced HbA1c (estimated treatment difference [ETD] − 0.32 to − 0.79%-points for semaglutide 0.5 mg, and − 0.38 to − 1.07%-points for semaglutide 1.0 mg vs comparators; p < 0.01) in subjects receiving both MET and MET + SU. Regardless of background OAD, semaglutide significantly reduced body weight (ETD − 2.35 to − 4.72 kg for semaglutide 0.5 mg, and − 2.96 to − 6.76 kg for semaglutide 1.0 mg vs comparators; p < 0.0001). Across the trials, hypoglycaemic events were more common with background MET + SU than MET alone, in subjects receiving either semaglutide or a comparator. The rate of adverse events (AEs) leading to premature treatment discontinuations in subjects treated with semaglutide were generally consistent regardless of background therapy.


Semaglutide 0.5 mg and 1.0 mg significantly improve glycaemic control (HbA1c) and body weight in subjects with T2D, with a similar tolerability profile, regardless of whether they receive background MET or MET + SU.
