Guidelines issued jointly by the American Heart Association, American College of Cardiology
and Heart Failure Society of America

New guidelines recommend the use of SGLT inhibitors for the prevention and treatment of heart failure and highlight the need to improve optimization of medical therapies during hospitalizations

The Woodlands, Texas, April 4, 2022 – Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) welcomes new guidelines for the management of heart failure issued jointly this past weekend by the American Heart Association (AHA), the American College of Cardiology (ACC) and the Heart Failure Society of America (HFSA). 

The guidelines now recommend the use of SGLT2 inhibitors in the prevention and treatment of heart failure with the highest-level recommendations among classes of therapy in each category.  The guidelines recommend SGLT2 inhibitors for the treatment of heart failure with reduced ejection fraction (HFrEF) with a recommendation equivalent to preexisting standard-of-care classes of therapy and for the treatment of heart failure with mildly reduced ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF) with a recommendation stronger than for any other class of therapy.  In support, the guidelines specifically cite clinical trials of two selective SGLT2 inhibitors recently approved for heart failure and the SOLOIST-WHF study of dual SGLT1 and SGLT2 inhibitor sotagliflozin in patients admitted for worsening heart failure. The guidelines also highlight the need to improve optimization of medical therapies during heart failure hospitalizations.

“We expect that the new joint guidelines issued this weekend by the three largest cardiology societies in the United States, along with the new guidelines issued last year by the European Society of Cardiology, will support the emerging adoption of SGLT2 inhibitors as a first line treatment standard across heart failure,” said Craig Granowitz, M.D., Ph.D., senior vice president and chief medical officer at Lexicon.  “We believe that sotagliflozin’s unique mechanism offers opportunities for differentiation within the class, supported by the results from the SOLOIST-WHF study referenced in the guidelines as well as from the SCORED study, additional analyses from which were presented at the American College of Cardiology 71st Annual Scientific Sessions this weekend.”

The “2022 AHA/ACC/HFSA Guideline of the Management of Heart Failure” replaces the “2013 ACCF/AHA Guideline for the Management of Heart Failure” and its accompanying “2017 ACC/AHA/HFSA Focused Update.”  The full guidelines were published in the Journal of the American College of Cardiology (JACC) and can be found at jacc.org.

About the SOLOIST-WHF and SCORED Studies

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.

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.

Both SOLOIST-WHF and SCORED 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 Recent Worsening Heart Failure” and “Sotagliflozin in Patients with Diabetes and Chronic Kidney Disease” 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.
