Sotagliflozin (SOTA), a dual SGLT1 and SGLT2 inhibitor, is indicated to reduce the risk of CV death and hospitalization for heart failure (HF) in adults with HF or type 2 diabetes (T2D), chronic kidney disease and other CV risk factors. SOTA has previously demonstrated glycemic efficacy as an adjunct to insulin therapy in patients with type 1 diabetes (InTandem program). This study assessed the safety and efficacy of SOTA in T2D participants with inadequate glycemic control on basal insulin with up to two glucose-lowering oral agents. This was a Phase 3, multicenter, double-blind, placebo (PBO)-controlled, parallel-group study that enrolled 570 T2D participants (baseline mean HbA1c 8.45%, age 62.4 yrs, T2D duration 14.8 yrs, BMI 32.4 kg/m2, basal insulin dose 51 IU), who were randomized 2:1:1 to once daily SOTA 400 mg, SOTA 200 mg, or PBO. Primary objective was superiority of SOTA 400 mg vs. PBO in HbA1c reduction following an 18-week core treatment period conducted without insulin adjustments. Subsequently, a 52-week extension period, allowed for insulin adjustment based on target FPGs. Adverse events were assessed over the 52-week period. At Week 18, SOTA 400 mg had a PBO-subtracted least squares (LS) mean HbA1c reduction of -0.55% (p&lt;0.0001). At week 52, the LS mean change in A1c from baseline was -0.57% in the SOTA 400 mg group and 0% with PBO (p=0.074). Week 18 and Week 52 LS mean differences in HbA1c for SOTA 200 mg vs, PBO were -0.45% (p&lt;0.0001), and -0.52% (p=0.13), respectively. Overall incidence of adverse events was comparable in all groups. Incidence of Level 2 hypoglycemia (&lt;54 mg/dL) were 17%, 22% and 21% for PBO and SOTA 200 and 400 mg, respectively, and there was only 1 episode of DKA with SOTA 400 mg.
In conclusion, SOTA 400 mg once day significantly improved HbA1c in T2D with inadequate glycemic control on basal insulin therapy with a slight increase in non-severe hypoglycemia.
