Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • KCCQ CSS < 85.
  • NYHA functional class II or III
  • A diagnosis of HCM consistent with the current American College of Cardiology Foundation/American Heart Association and European Society of Cardiology guideline definition: unexplained left ventricular (LV) hypertrophy with nondilated ventricular chambers in the absence of other cardiac (eg, hypertension, aortic stenosis) or systemic disease with maximal LV wall thickness ≥ 15 millimeters (mm), or ≥ 13 mm with positive family history of HCM.
  • For obstructive hypertrophic cardiomyopathy (oHCM), left ventricular outflow tract (LVOT) peak gradient ≥ 30 millimetre of mercury (mm Hg) during screening as assessed by echocardiography at rest or during a valsalva maneuver.
  • For nonobstructive hypertrophic cardiomyopathy (nHCM), LVOT peak gradient < 30 mm Hg during screening as assessed by echocardiography at rest and < 30 mm Hg during a valsalva maneuver.
  • Screening left ventricular ejection fraction (LVEF) ≥ 50%, except for those on a cardiac myosin inhibitor (screening LVEF ≥ 55%).
  • For participants on a cardiac myosin inhibitor, the dose must be stable at least 3 months prior to screening. Participants on cardiac myosin inhibitor should not be scheduled for up-titration during the trial.
  • Stable doses of background therapy (ie, β-blockers, calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers, diuretics) for at least 1 month prior to screening.

Who cannot join

  • Received therapy with a sodium glucose co-transporter 2 (SGLT2) inhibitor within the past 8 weeks prior to screening.
  • Previous intolerance to an SGLT2 inhibitor.
  • Any previous treatment with sotagliflozin.
  • Current use of thiazolidinediones or digoxin.
  • Current/planned participation in another interventional clinical trial or prior participation in any interventional trial with an investigational agent within 45 days of screening.

  • Has paroxysmal, persistent, or permanent atrial fibrillation not on anticoagulation for at least 4 weeks prior to screening and/or not adequately rate controlled within 3 months of screening.
  • Septal reduction therapy planned during the study period. For participants who had septal reduction therapy, the procedure should have been completed more than 3 months prior to screening.
  • Cardiac surgery (eg, coronary artery bypass graft, valvular repair/replacement), percutaneous coronary intervention, or implantation of cardiac device (pacemaker or implantable cardioverter defibrillator) within 3 months prior to screening or planned during the study period.

About this study

Official title: A Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter Study to Evaluate the Efficacy and Safety of SOtaglifloziN in symptomATic Obstructive And Non-obstructive Hypertrophic CardioMyopathy (SONATA-HCM)

The main purpose of the study is to determine the changes in symptoms and functional limitations in participants with symptomatic hypertrophic cardiomyopathy (HCM) treated with sotagliflozin as compared to placebo.

Being tested
Sotagliflozin, Placebo
Medical subject headings
Cardiomyopathy, Hypertrophic

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SotagliflozinDrug

    Also called SAR439954/LX4211

    Sotagliflozin will be administered as a tablet(s), orally once daily.

  • PlaceboDrug

    Also called SAR439954/LX4211

    Placebo will be administered as a tablet(s) (identical to the sotagliflozin tablet in appearance), orally once daily.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from Baseline to Week 26 in Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ CSS)

    KCCQ is a 23-item, self-administered questionnaire that measure the participant's perception of their health status, including their heart failure (HF) symptoms, impact on physical and social function and how their HF impacts the quality of life. KCCQ quantifies 7 domains: physical limitations (6 items), symptom stability (1 item), symptom frequency (4 items), symptom burden (3 items), self-efficacy (2 items), quality of life (3 items) and social limitations (4 items). Scores are generated for each domain and scaled from 0 to 100, with 0 denoting the worst and 100 the best possible status. Higher scores reflect better health status.

    Measured: Baseline to Week 26

Secondary outcomes (2)

  1. Percentage of Participants at Week 26 with a New York Heart Association (NYHA) Functional Class Improvement ≥ 1 Category

    NYHA functional class is a clinician-reported assessment of participants' health status on a 4-point scale, where Class I represents no limitations in normal activity; Class II indicates slight limitation of physical activity; Class III indicates marked limitation in physical activity; and Class IV indicates that participants have symptoms with any physical activity or at rest. Percentage of participants with NYHA functional class improvement ≥1 will be reported.

    Measured: Week 26

  2. Change from Baseline to Week 26 in KCCQ Total Symptom Score (TSS).

    KCCQ is a 23-item, self-administered questionnaire that measure the participant's perception of their health status, including their HF symptoms, impact on physical and social function and how their HF impacts the quality of life. KCCQ quantifies 7 domains: physical limitations (6 items), symptom stability (1 item), symptom frequency (4 items), symptom burden (3 items), self-efficacy (2 items), quality of life (3 items) and social limitations (4 items). Scores are generated for each domain and scaled from 0 to 100, with 0 denoting the worst and 100 the best possible status. Higher scores reflect better health status.

    Measured: Baseline to Week 26

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Sotagliflozin in people with Obstructive Cardiomyopathy, Hypertrophic and Non-obstructive Hypertrophic Cardiomyopathy, run by Lexicon Pharmaceuticals at 108 sites in 19 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 108 sites in United States, Israel, Argentina, Portugal, France and 14 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Baseline to Week 26 in Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ CSS) (time frame: Baseline to Week 26). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06481891.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2026.
