Abstract

Background: The SCORED (Effect of Sotagliflozin on Cardiovascular and Renal Events in Patients with Type 2 Diabetes and Moderate Renal Impairment Who Are at Cardiovascular Risk) and SOLOIST-WHF (Effect of Sotagliflozin on Cardiovascular Events in Patients with Type 2 Diabetes Post Worsening Heart Failure) trials demonstrated that sotagliflozin, an SGLT1 and SGLT2 inhibitor, improves outcomes in individuals with type 2 diabetes who have heart failure (HF) or kidney disease.

Objectives: We assessed the efficacy of sotagliflozin on HF clinical outcomes in individuals with differing baseline glycosylated hemoglobin (HbA1c) levels.

Methods: We included all adults from SCORED and SOLOIST-WHF. The primary outcome was a composite of cardiovascular death, hospitalizations for HF, and urgent visits for HF. The efficacy of sotagliflozin compared with placebo was evaluated by baseline HbA1c using competing-risk marginal proportional hazards models.

Results: We identified 11,744 adults. Individuals with HbA1c ≤7.5% experienced the primary outcome at a lower rate in the sotagliflozin group (11.2 per 100 person-years) than the placebo group (15.5 per 100 person-years) (HR: 0.73; 95% CI: 0.57-0.93). Similarly, individuals with HbA1c of 7.6% to 9.0% experienced the primary outcome at a lower rate in the sotagliflozin group (7.3 per 100 person-years) than the placebo group (9.4 per 100 person-years) (HR: 0.77; 95% CI: 0.63-0.96). These findings were also consistent among individuals with HbA1c >9.0%, with a primary outcome rate in the sotagliflozin group (7.8 per 100 person-years) that was lower than the placebo group (11.6 per 100 person-years) (HR: 0.65; 95% CI: 0.50-0.84). The efficacy of sotagliflozin was consistent by baseline HbA1c level (P for interaction = 0.58).

Conclusions: In individuals with type 2 diabetes and either HF or kidney disease, sotagliflozin reduced HF outcomes irrespective of baseline HbA1c.
