Lexicon Pharmaceuticals Highlights Publications Relating to Sotagliflozin’s Differentiated Dual SGLT1 and SGLT2 Mechanism of Action and Potential Implications for Cardiovascular Disease

Results to be Presented at the European Society for Cardiology Congress Demonstrate Differential Effects During Endothelial Dysfunction in Cell Studies

Recent Publication in the Journal Diabetes Care Evaluates Metabolic, Intestinal and Cardiovascular Effects in a Clinical Study

THE WOODLANDS, Texas, Aug. 22, 2022 (GLOBE NEWSWIRE) — Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced a series of publications concluding that sotagliflozin’s differentiated dual SGLT1 and SGLT2 mechanism of action may have implications for cardiovascular disease.

• Two posters will be presented on August 28^th and August 29^th at the 70^th annual European Society of Cardiology Congress, highlighting protein expression analyses comparing sotagliflozin, a dual SGLT1 and SGLT2 inhibitor, with a selective SGLT2 inhibitor in cell-based models relative to inflammation and thrombosis.
  • The first poster, “Sotagliflozin, a Dual SGLT1/2 Inhibitor, Reduced Expression of Neutrophil Degranulation Proteins During Endothelial Dysfunction Compared with a Selective SGLT2 Inhibitor,” concludes that the favorable effects of sotagliflozin on mechanisms of inflammation have implications for ischemic disease, including myocardial infarction and stroke.
  • The second poster, “Sotagliflozin, a Dual SGLT1/2 Inhibitor, Reduced Expression of Platelet Activators During Endothelial Dysfunction Compared to Empagliflozin,” concludes that the effects of dual SGLT1 and SGLT2 inhibition on platelet activity may have implications for reduced atherothrombotic risk.
• A manuscript entitled “Metabolic, Intestinal, and Cardiovascular Effects of Sotagliflozin Compared with Empagliflozin in Patients with Type 2 Diabetes: A Randomized, Double-Blind Study” was recently published online ahead of print in the journal Diabetes Care. Results from the study showed that, while both agents demonstrated similar effects on many cardiometabolic measures, there were differences in others, such as incremental incretin levels following meals, noted as having potential implications for cardiovascular disease.

“We believe these studies add to the growing body of evidence of the potential benefits of dual SGLT1 and SGLT2 inhibition, and the differentiating effects of the SGLT1 component of sotagliflozin’s mechanism of action on measures with potential implications for cardiovascular disease” said Dr. Craig Granowitz, Lexicon’s senior vice president and chief medical officer. “The results of these studies offer mechanistic evidence supporting the cardioprotective results observed in the SCORED and SOLOIST-WHF Phase 3 cardiovascular outcomes studies which form the basis of Lexicon’s new drug application for FDA approval of sotagliflozin for the treatment of heart failure, including in patients with acute or worsening heart failure.”

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.
