THE WOODLANDS, Texas, Aug. 31, 2026 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced results from a post hoc analysis of the Phase 3 SOLOIST-WHF trial evaluating the efficacy and safety of sotagliflozin across the spectrum of baseline systolic blood pressure in patients recently hospitalized for worsening heart failure.
The data, which were presented yesterday at ESC Congress 2026 in Munich, Germany and simultaneously published in JACC: Heart Failure1, demonstrated that the results of sotagliflozin treatment were maintained regardless of baseline systolic blood pressure. Among patients with baseline systolic blood pressure as low as 100 mmHg, treatment with sotagliflozin was associated with a reduction in cardiovascular death and heart failure-related events, without an increase in hypotension or acute kidney injury (AKI).
“Patients hospitalized for recent worsening heart failure and lower systolic blood pressure are often considered among the most clinically vulnerable,” said Craig Granowitz, M.D., Ph.D., Lexicon’s senior vice president and chief medical officer. “We were encouraged to see that the results of sotagliflozin treatment remained consistent across the spectrum of baseline blood pressure in SOLOIST-WHF, providing additional insight into the potential utility of sotagliflozin in a particularly high-risk heart failure population.”
The SOLOIST-WHF trial randomized 1,222 patients with type 2 diabetes admitted for worsening heart failure to treatment with the dual SGLT 1 and 2 inhibitor sotagliflozin or placebo. The analysis demonstrated that the effect of sotagliflozin was consistent across the spectrum of baseline systolic blood pressure (SBP), with no evidence that treatment effect varied by baseline blood pressure.
Among patients with a baseline SBP <110 mmHg (n=201), those randomized to sotagliflozin experienced a reduction in total occurrences of cardiovascular deaths and HF-related events (HR 0.56 (95% CI 0.33-0.95), p=0.03). These data suggest efficacy of sotagliflozin in even the lowest SBP stratum. There was no difference in the incidence of adverse events of hypotension between treatment groups (p=0.34) or AKI (p=0.69). Additionally, patients with a baseline SBP ≥ 110 mmHg (n=1175) also experienced a reduction in total occurrences of cardiovascular deaths and HF-related events (HR 0.69 (95%CI 0.53-0.91), p=0.01).
About Sotagliflozin
Discovered using Lexicon’s unique approach to gene science, sotagliflozin is an oral inhibitor of two proteins responsible for glucose regulation known as sodium-glucose cotransporter types 2 and 1 (SGLT2 and SGLT1). SGLT2 is responsible for glucose and sodium reabsorption by the kidney and SGLT1 is responsible for glucose and sodium absorption in the gastrointestinal tract. Sotagliflozin has been studied in multiple patient populations encompassing heart failure, diabetes, and chronic kidney disease in clinical studies involving approximately 20,000 patients. Sotagliflozin is also currently under investigation for another cardiac condition, hypertrophic cardiomyopathy (HCM).
