Effect of sotagliflozin as an adjunct to insulin therapy on blood pressure and arterial stiffness in adults with type 1 diabetes: A post hoc pooled analysis of inTandem1 and inTandem2

Objective:Evaluate the effect of sotagliflozin, a dual inhibitor of sodium glucose cotransporter (SGLT) 1 and 2, on arterial stiffness in patients with type 1 diabetes (T1D) treated with sotagliflozin as adjunct to optimized insulin therapy.Methods:In this post hoc analysis, indirect markers of arterial stiffness, including pulse pressure, mean arterial pressure (MAP), and double product, were calculated using observed systolic blood pressure (SBP), diastolic blood pressure (DBP), or pulse rate at 24 weeks using data from a pooled patient population from the inTandem1 and inTandem2 randomized controlled trials (n = 1575).Results:Baseline characteristics were similar among groups. Relative to placebo at Week 24, sotagliflozin 200 mg and 400 mg reduced SBP by 2.03 mm Hg (95% CI −3.30 to −0.75; p = 0.0019) and 2.85 mm Hg (−4.12 to −1.57; p p Conclusion:In adults with T1D, adding sotagliflozin to insulin significantly reduced blood pressure and other markers of arterial stiffness and vascular resistance.
