101-OR: Efficacy and Safety of Once-Weekly Semaglutide 2.0 vs. 1.0 mg for Type 2 Diabetes: SUSTAIN FORTE Randomized Trial

2021 
Once-weekly (OW) subcutaneous semaglutide 0.5 and 1.0 mg are approved maintenance doses for type 2 diabetes (T2D) treatment. We hypothesized that a higher dose of 2.0 mg would provide additional glycemic control with more patients achieving treatment targets vs. 1.0 mg. SUSTAIN FORTE (NCT03989232) was a randomized, double-blind, phase 3b trial investigating the efficacy and safety of OW semaglutide 2.0 vs. 1.0 mg after 40 weeks of treatment in 961 adults with T2D in need of treatment intensification (HbA1c 8.0-10.0%) on stable metformin ± sulfonylurea. All participants initiated semaglutide treatment with the 0.25 mg dose, doubling every 4 weeks until target dose was reached. The primary objective was to establish superiority of semaglutide 2.0 vs. 1.0 mg on glycemic control; secondary objectives included comparison of the effect on body weight (BW) (confirmatory), safety and tolerability. Baseline characteristics and key results are shown in the Table. Superior HbA1c and BW reductions were shown with semaglutide 2.0 vs. 1.0 mg and a greater proportion of participants achieved HbA1c In conclusion, semaglutide 2.0 mg is superior to 1.0 mg in reducing HbA1c and BW, with a comparable safety profile.
