LXRX Lexicon Pharmaceuticals Inc

Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced that it will unveil study design details of SONATA-HCM, the company’s Phase 3 clinical trial of sotagliflozin as a potential new treatment for adults with hypertrophic cardiomyopathy (HCM), at the virtual Hypertrophic Cardiomyopathy Medical Society (HCMS) 2024 Scientific Sessions. Lexicon plans to conduct the multinational study at 130 sites in 20 countries and enroll adults aged 18 years or older diagnosed with symptomatic HCM, either obstructive (oHCM) or non-obstructive (nHCM). Initial study sites have been activated and patient randomization is underway.

Details for the presentation on “A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Study to Evaluate the Efficacy and Safety of SOtaglifloziN in Patients with SymptomATic obstructive And non-obstructive Hypertrophic CardioMyopathy (SONATA-HCM)” is as follows:

• HCMS (virtual) – a moderated poster presentation, Friday, September 27, 2:00-2:30p.m. ET, presented by Carolyn Y. Ho, M.D., Cardiology, Brigham and Women’s Hospital, Boston, MA

The estimated prevalence of HCM in the United States is about 1.1 million. The most common patient-reported symptoms include shortness of breath, lightheadedness or dizziness, fatigue, heart fluttering or palpitations, and limitations to physical activities.

“SONATA-HCM will evaluate the efficacy of sotagliflozin, a dual SGLT2 and SGLT1 inhibitor, on symptoms, function, and other patient-reported outcomes, as well as safety in patients with symptomatic HCM,” said Dr. Ho, M.D., Cardiology, Brigham and Women’s Hospital, and a co-author of the study abstract.

“Despite recent advances in the treatment of HCM, there remain significant needs among patients and clinicians for new therapeutic options,” said Sharlene M. Day, M.D., Director, Translational Research, Division of Cardiovascular Medicine and Cardiovascular Institute, Presidential Associate Professor, University of Pennsylvania Medicine, and a co-author of the study abstract. “Although HCM is a unique condition, there are overlapping features with other conditions that lead to heart failure, so I’m optimistic that sotagliflozin could work in this patient population.”

“We are excited about the potential for sotagliflozin to become a safe and effective treatment for HCM, either as standalone therapy or in conjunction with currently available medications,” said Craig Granowitz, M.D., Ph.D., Lexicon’s senior vice president and chief medical officer. “Based on our interactions with FDA, and if supported by positive study results, we plan to submit a supplemental new drug application (sNDA) with a broad proposed label to improve symptoms and physical limitations in adults with HCM.”

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