Abstract
OBJECTIVE
Treatment intensification with additional anti-diabetic agents is recommended in type 2 diabetes (T2D) for patients inadequately controlled on metformin monotherapy. The present network meta-analysis (NMA) evaluated comparative efficacy and safety of once-weekly semaglutide and sodium-glucose co-transporter 2 inhibitors (SGLT-2is) in T2D patients inadequately controlled with metformin.
METHODS
Randomized controlled trials with ≥20 weeks duration were searched in EMBASE, MEDLINE, and CENTRAL. Primary efficacy outcomes were: change from baseline in HbA1c, weight, systolic blood pressure (SBP), post-prandial blood glucose (PPG), and fasting blood glucose (FPG). Treatment effects at 26 (±4) weeks were compared using Bayesian NMAs. Meta-regression and sensitivity analysis were used to address the trial heterogeneity.
RESULTS
Eight trials were found eligible for this NMA. Statistically significant reductions in HbA1c were observed with both 1.0 mg and 0.5 mg doses of once-weekly semaglutide when compared to SGLT-2is. The mean differences in change from baseline in HbA1c for once-weekly semaglutide 1.0 mg vs SGLT-2is ranged from -0.66% for canagliflozin 300 mg (95% Credible Intervals [CrI]: -0.82, -0.50%) to -1.11% for dapagliflozin 5 mg (95% CrI: -1.37, -0.85%). Once-weekly semaglutide 1.0 mg performed significantly better than all SGLT-2is of interest in reducing weight and improving FPG levels: however, SBP reduction was not statistically differentiable. Results of sensitivity analysis and meta-regressions aligned with base-case results. NMAs were not possible for PPG and safety outcomes, due to lack of data.
CONCLUSION
Once-weekly semaglutide treatment is significantly better compared to SGLT-2is in achieving adequate glycemic control in T2D patients inadequately controlled with metformin monotherapy.
