SONATA-HCM Study Design Presented at Heart Failure 2025, the Annual Congress of the Heart Failure Association of the European Society of Cardiology
Lexicon Pharmaceuticals (NASDAQ: LXRX) presented the design of its SONATA-HCM Phase 3 clinical trial at Heart Failure 2025, evaluating sotagliflozin for both obstructive and non-obstructive hypertrophic cardiomyopathy (HCM). The study is actively enrolling 500 patients across 20 countries, with all sites expected to be operational by September 2025.
The trial aims to assess sotagliflozin's efficacy on symptoms, function, and patient-reported outcomes in HCM patients. The primary endpoint measures symptom improvement using the Kansas City Cardiomyopathy Questionnaire at week 26. Recent evidence published in The Lancet (February 2025) suggests sotagliflozin's dual SGLT1 and SGLT2 inhibition reduces major adverse cardiovascular events.
If successful, the study could support a supplemental new drug application (sNDA) for sotagliflozin in both HCM types, addressing a significant unmet need, particularly for non-obstructive HCM where no approved therapies exist.Lexicon Pharmaceuticals (NASDAQ: LXRX) ha presentato il disegno del suo studio clinico di fase 3 SONATA-HCM al congresso Heart Failure 2025, valutando sotagliflozin sia per la cardiomiopatia ipertrofica ostruttiva sia non ostruttiva (HCM). Lo studio sta reclutando attivamente 500 pazienti in 20 paesi, con l'obiettivo che tutti i centri siano operativi entro settembre 2025.
Il trial mira a valutare l'efficacia di sotagliflozin sui sintomi, la funzionalità e gli esiti riportati dai pazienti affetti da HCM. L'endpoint primario misura il miglioramento dei sintomi tramite il Kansas City Cardiomyopathy Questionnaire alla settimana 26. Evidenze recenti pubblicate su The Lancet (febbraio 2025) indicano che l'inibizione duale di SGLT1 e SGLT2 da parte di sotagliflozin riduce gli eventi cardiovascolari avversi maggiori.
Se i risultati saranno positivi, lo studio potrebbe supportare una domanda supplementare di approvazione del farmaco (sNDA) per sotagliflozin in entrambi i tipi di HCM, rispondendo a un bisogno clinico significativo, soprattutto per la HCM non ostruttiva, per la quale non esistono terapie approvate.

Insights
Lexicon's Phase 3 SONATA-HCM trial for sotagliflozin presents a significant opportunity to address unmet needs in hypertrophic cardiomyopathy treatment.
Lexicon's SONATA-HCM trial represents a potentially significant advancement in the treatment landscape for hypertrophic cardiomyopathy (HCM). As the only ongoing Phase 3 study that includes both obstructive and non-obstructive HCM patients, this positions Lexicon uniquely in the field. The trial design is particularly notable for its inclusivity of non-obstructive HCM patients – a population with no currently approved therapies, highlighting a substantial unmet medical need.
The study's robust design includes 500 patients across 20 countries, evenly split between obstructive and non-obstructive HCM subtypes. The primary endpoint focuses on symptomatic improvement measured by the validated Kansas City Cardiomyopathy Questionnaire, an appropriate patient-centered outcome for this condition where quality of life impairment is significant.
Sotagliflozin's dual inhibition of both SGLT1 and SGLT2 differentiates it from other SGLT2-only inhibitors. The press release references recent evidence published in The Lancet suggesting this dual mechanism reduces major adverse cardiovascular events. This pharmacological profile could potentially address the complex pathophysiology of HCM, though this remains to be proven in the current trial.
If successful, this trial could support a supplemental new drug application that would expand sotagliflozin's approved indications. The drug already has an established safety record in heart failure, which could streamline regulatory consideration. For HCM patients, especially those with the non-obstructive variant who currently lack treatment options, sotagliflozin could represent a significant therapeutic advance.
Lexicon is evaluating the safety and efficacy of sotagliflozin in patients with both obstructive and non-obstructive hypertrophic cardiomyopathy (HCM)
Pivotal Phase 3 clinical trial is actively enrolling patients in 20 countries, with all sites expected to be operational by Q3 2025
THE WOODLANDS, Texas, May 19, 2025 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced details of its “SOtaglifloziN in Patients with SymptomATic obstructive And non-obstructive Hypertrophic CardioMyopathy (SONATA-HCM)” study were presented on Saturday, May 17. The study design was disclosed in Belgrade, Serbia at one of the premier international heart failure meetings: Heart Failure 2025, the Annual Congress of the Heart Failure Association of the European Society of Cardiology.
Enrollment is underway in SONATA-HCM, with all study sites in 20 countries expected to be operational by September 2025. Lexicon believes there is potential for the study results to support a supplemental new drug application (sNDA) for sotagliflozin for both obstructive and non-obstructive HCM.
SONATA-HCM is the only ongoing Phase 3 study in both obstructive and non-obstructive HCM. It is a randomized, double-blind, placebo-controlled multicenter trial that will evaluate the efficacy of sotagliflozin, a dual SGLT1 and SGLT2 inhibitor, on symptoms, function, and other patient-reported outcomes, as well as safety in patients with symptomatic HCM. The study is designed to enroll 500 patients worldwide, 250 with obstructive HCM and 250 with non-obstructive HCM. The primary efficacy endpoint is improvement in symptoms, as measured by change from baseline to week 26, in the Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ) CSS survey.
"There is a huge unmet need for people suffering from HCM, with no approved or effective therapies for non-obstructive HCM," said Sharlene M. Day, M.D., co-principal investigator for SONATA-HCM and Presidential Professor and Director of Translational Research in the Division of Cardiovascular Medicine and the Cardiovascular Institute at the University of Pennsylvania Perelman School of Medicine. "I'm very excited to be testing the potential for sotagliflozin to improve symptoms in a broad number of patients across the spectrum of HCM, as has previously been demonstrated in patients with heart failure with reduced and preserved ejection fraction. Sotagliflozin’s tolerability profile and immediate benefits observed in patients with heart failure could potentially make it a very appealing option for patients with HCM if the benefits do indeed extend to this population."
As a chronic, progressive disease, HCM can worsen over time and lead to other complications, including heart failure and stroke. Sotagliflozin is a proven drug for the treatment of heart failure, with an established safety record and significant use in clinical practice. A growing body of evidence suggests that sotagliflozin’s dual inhibition of SGLT1 and SGLT2 reduces the risk of major adverse cardiovascular events (MACE), including heart attack and stroke, as most recently published in The Lancet in February 2025.
“SONATA-HCM is an important study with the potential to support a broad label to enhance the care of patients with both obstructive and non-obstructive HCM,” said Craig Granowitz, M.D., Ph.D., Lexicon’s senior vice president and chief medical officer.

About Sotagliflozin
Discovered 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.
