- Abstract
Introduction: A slower adoption rate of fixed dose combinations (FDC) in diabetes management is partly due to insufficient data. This study evaluates the safety and efficacy of an FDC of dapagliflozin + sitagliptin + metformin hydrochloride extended release (XR), compared to a dual FDC of sitagliptin + metformin hydrochloride XR among patients with type 2 diabetes mellitus (T2DM) with poor glycemic control when treated with metformin monotherapy., Methods: A total of 274 patients with T2DM were randomized (1:1) to either arm X, receiving FDC of dapagliflozin (10 mg) + sitagliptin (100 mg) + metformin hydrochloride XR (1000 mg) (Dapa + Sita + Met) tablets, or arm Y, receiving sitagliptin phosphate (100 mg) + metformin hydrochloride XR (1000 mg) (Sita + Met) tablets, and treated for 16 weeks. The outcome measures included changes in hemoglobin A1c (HbA1c)(%), fasting plasma glucose (FPG), 2-h post-prandial glucose (PPG), weight, and the proportion of patients achieving target HbA1c levels of < 7.0% by week 16 of the study period., Results: The reduction in HbA1c at week 16 was significantly higher in arm X than in arm Y [estimated treatment difference (ETD), - 0.65% (95% CI - 0.76 to - 0.53; P < 0.0001)]. Arm X showed a marked decrease in FPG [ETD - 15.42 mg/dl; 95% CI (17.63, 13.22; P < 0.0001)], PPG [ETD - 30.39 mg/dl; 95% CI (35.59, 25.19; P < 0.0001)], and weight [ETD - 1.47 kg; 95% CI (1.59, 1.28; P < 0.0001)] after 16 weeks. In arm X, 54% of patients reached HbA1c < 7.0% compared to 29.9% in arm Y. The incidence of adverse events was comparable [13.14% (arm X) vs 12.4% (arm Y)]. There was no severe hypoglycemia-led treatment discontinuation., Conclusion: Among patients with T2DM who have poor glycemic control with metformin monotherapy, triple FDC (Dapa + Sita + Met) effectively helped achieve better glycemic response compared to dual FDC (Sita + Met), with a comparable safety and tolerability profile., Trial Registration: CTRI/2022/01/039857., Competing Interests: Declarations.
