Lexicon Pharmaceuticals Provides Regulatory Update on Sotagliflozin in Heart Failure

THE WOODLANDS, Texas, Jan. 14, 2021 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. LXRX announced today that it has received U.S. Food and Drug Administration (FDA) regulatory feedback that the results of its SOLOIST and SCORED Phase 3 clinical studies can support a new drug application (NDA) submission for an indication to reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent visits for heart failure in adult patients with type 2 diabetes with either worsening heart failure or additional risk factors for heart failure.

The feedback was provided in response to a request made by Lexicon following the completion of the SOLOIST and SCORED studies relating to the potential submission of an NDA based on the results of such studies, taking into account their early close-out and other considerations. This regulatory feedback clears a key hurdle for partnership discussions around sotagliflozin in heart failure and enables a potential NDA filing in 2021.

Lonnel Coats, Lexicon's president and chief executive officer, will present at the 39^th Annual J.P. Morgan Healthcare Conference today at 2:50 p.m. ET. A webcast of the event will be available in the "Events" section of the Lexicon website at www.lexpharma.com.

About the SOLOIST and SCORED Studies

SOLOIST 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.

Both SOLOIST and SCORED achieved their respective primary endpoints. 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."

About Sotagliflozin

Discovered using Lexicon's unique approach to gene science, sotagliflozin is an 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 is approved in the European Union (EU) for use as an adjunct to insulin therapy to improve blood sugar (glycemic) control in adults with type 1 diabetes with a body mass index ≥ 27 kg/m², who could not achieve adequate glycemic control despite optimal insulin therapy, but has not yet been commercially launched.
