Background: SGLT inhibitors reduce the risk of cardiovascular (CV) events in patients with heart failure (HF) and chronic kidney disease regardless of diabetes status. Although the SOLOIST-WHF and SCORED trials enrolled high CV risk patients with T2DM, participants had a wide range of baseline A1C values. Thus, the present analysis evaluated the effects of sotagliflozin relative to placebo on cardiovascular (CV) death and total HF-related outcomes by baseline A1C range.
Methods: SOLOIST-WHF had no baseline A1C entry criteria (baseline median = 7.1%, range = 4.5, 15.0%), while SCORED randomized patients with T2DM and an A1C ≥7% at screening (8.3%, 6.5, 17.3%). Natural cubic splines from Poisson regression models estimated the relationships between continuous A1C and the primary endpoint for both studies: total number of CV deaths, hospitalizations for HF, and urgent visits for HF.
Results: Within each trial, patients with higher baseline A1C experienced higher event rates (spline effect p=0.0349 and 0.0014 for SOLOIST-WHF and SCORED, respectively). Sotagliflozin reduced the primary outcome in each trial (p for treatment <0.0001 for both SOLOIST-WHF and SCORED) and this did not differ across A1C (p for interaction >0.10; Figure).
Conclusion: Sotagliflozin was effective in reducing the risk of CV death and HF-related events independent of baseline A1C.
