lexicon WELCOMES NEW ESC HEART FAILURE TREATMENT GUIDELINES ESTABLISHING SGLT INHIBITORS AS STANDARD OF CARE

The Woodlands, Texas, August [30], 2021 – Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) welcomes the new recommendation by the European Society of Cardiology (ESC) to add SGLT inhibitors as part of the standard of care for the treatment of heart failure (HF). SGLT inhibitors have been given a Class IA recommendation-- the strongest endorsement-- in updated clinical practice guidelines released by the ESC Heart Failure working group in the EU at their annual meeting, the ESC Congress 2021 - The Digital Experience.

Specifically, the guidelines recommend the following for the management of patients with HF with reduced ejection fraction (HFrEF) and diabetes or for the treatment of diabetes in HFrEF:

• SGLT2 inhibitors (canagliflozin, dapagliflozin, empagliflozin, ertugliflozin, sotagliflozin) are recommended in patients with type 2 diabetes (T2DM) at risk of cardiovascular (CV) events to reduce hospitalizations for HF, major CV events, end-stage renal dysfunction, and CV death.
• SGLT2 inhibitors (dapagliflozin, empagliflozin, and sotagliflozin) are recommended in patients with T2DM and HFrEF to reduce hospitalizations for HF and CV death.

The guidelines addressed worsening heart failure noting:

• The combined SGLT-1 and 2 inhibitor, sotagliflozin, has also been studied in patients with diabetes who were hospitalized with HF.  The drug reduced CV death and hospitalization for HF.
• Safety and better outcome have also been recently shown in a prospective randomized trial with sotagliflozin in diabetic patients hospitalized for HF, irrespective of their left ventricular ejection fraction (LVEF).

“It is quite rare for an investigational drug to be listed in the guidelines prior to approval and we do not take the trust and confidence that ESC has placed in sotagliflozin lightly,” said Craig Granowitz, M.D., Ph.D., senior vice president and chief medical officer at Lexicon. “We know patients with heart failure suffer reduced quality of life and remain at high risk of hospitalization or death, and these new guidelines are a strong call to action to ensure patients receive the most effective therapies for acute and chronic heart failure.  We continue to work diligently for these patients and plan to submit a New Drug Application with the U.S. Food and Drug Administration later this year for sotagliflozin, as a therapy for people suffering from heart failure and living with type 2 diabetes.”

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.
