New Analyses of Sotagliflozin From the SOLOIST-WHF and SCORED Trials in High Cardiovascular Risk Patients to be Presented at the American Heart Association Scientific Sessions 2022

Featured oral presentation on the effect of sotagliflozin on cardiovascular mortality and hospital readmission rates for heart failure at 30- and 90-days post discharge

THE WOODLANDS, Texas, Oct. 31, 2022 (GLOBE NEWSWIRE) — Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), today announced the upcoming presentation of new analyses of results from the SOLOIST-WHF and SCORED Phase 3 outcomes studies of its investigational sotagliflozin product at the American Heart Association Scientific Sessions 2022 in Chicago, Illinois.

The following analyses of sotagliflozin have been selected for oral and poster presentations:

• “The effect of the dual SGLT1 and 2 inhibitor sotagliflozin on cardiovascular mortality and hospital readmission rates for heart failure at 30- and 90-days post discharge in patients with type 2 diabetes hospitalized for worsening heart failure in the SOLOIST-WHF trial”, an oral presentation on Sunday, November 6^th at 4:18 pm CT during the ‘Advances in Diabetes and Heart Failure: From Bench to Bedside’ session
• “Comparison of investigator-reported and adjudicated events from SOLOIST-WHF and SCORED”, to be presented on Saturday, November 5^th at 11:00 am CT as a moderated poster during the ‘Heart Failure Management With or Without Diabetes’ session
• “Sotagliflozin, a dual SGLT-1/2 inhibitor, modulated expression of endothelial proteins that inhibit reactive oxygen species during inflammation compared with Empagliflozin”, will be presented on November 5^th at 3:00 pm CT during the ‘Inflammation in Diseases: Therapeutic Implications’ session

About the SCORED and SOLOIST-WHF Studies

SCORED was a multi-center, randomized, double-blinded, placebo-controlled Phase 3 study evaluating the cardiovascular efficacy of sotagliflozin versus placebo when added to standard of care in 10,584 patients with type 2 diabetes, chronic kidney disease with eGFR of 25 to 60 ml per minute per 1.73 m² of body-surface area, and risks for cardiovascular disease. The primary endpoint was the total number of events comprised of deaths from cardiovascular causes, hospitalizations for heart failure, and urgent visits for heart failure in patients treated with sotagliflozin compared with placebo. Key secondary endpoints included total number of events of deaths from cardiovascular causes, non-fatal myocardial infarction, and non-fatal stroke.

SOLOIST-WHF was a multi-center, randomized, double-blinded, placebo-controlled Phase 3 study evaluating the cardiovascular efficacy of sotagliflozin versus placebo when added to standard of care in 1,222 patients with type 2 diabetes who had recently been hospitalized for worsening heart failure. The primary endpoint was the total number of events comprised of deaths from cardiovascular causes, hospitalizations for heart failure, and urgent visits for heart failure in patients treated with sotagliflozin compared with placebo.

Both SCORED and SOLOIST-WHF achieved their respective primary endpoints, with overall tolerability similar to placebo across both trials. Results from both studies were presented at the Late-Breaking Science Session of the American Heart Association (AHA) Scientific Sessions 2020 and simultaneously published in The New England Journal of Medicine (NEJM) in two separate articles titled: “Sotagliflozin in Patients with Diabetes and Chronic Kidney Disease” and “Sotagliflozin in Patients with Diabetes and Recent Worsening Heart Failure” which may be accessed at www.nejm.org.

About Sotagliflozin

Discovered using Lexicon’s unique approach to gene science, sotagliflozin is an investigational oral dual inhibitor of two proteins responsible for glucose regulation known as sodium-glucose co-transporter types 1 and 2 (SGLT1 and SGLT2). SGLT1 is responsible for glucose absorption in the gastrointestinal tract, and SGLT2 is responsible for glucose reabsorption by the kidney. Sotagliflozin has been studied in multiple patient populations encompassing heart failure, type 1 and type 2 diabetes, and chronic kidney disease in fourteen Phase 3 clinical studies involving approximately 20,000 patients.
