What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Procedures mentioned: MRI scans, Blood draws

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "Subjects will have their first dose (400mg/kg) upon completion of the baseline Magnetic Resonance Imaging (MRI), and then a second dose (400mg/kg) approximately 1.5 hours after their consumption of the 1st dose."
  • "Approximately 1.5 hours after their second dose (3hr since first dose), the subject will undergo a second cardiac MRI."
  • "An IV catheter will be placed into one antecubital vein by a study nurse for all blood draws during visit 2."
  • "The subject will then be asked to return to complete a third MRI approximately 24 hours after their second MRI."
  • "An IV catheter will be placed into one antecubital vein by a study nurse for all blood draws during visit 3."
  • "After completion of the third MRI, subjects will be dosed KE 400mg/kg once daily until the visit 4 MRI can be completed."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

This study will provide insight into whether cardiac function changes with oral Ketone Esters (KE) administered to patients with Type 2 Diabetes Mellitus (T2DM) and Heart failure with reduced ejection fraction (HFrEF). Plasma ketones are avidly extracted by cardiac muscle and their uptake is not dependent upon insulin or influenced by insulin resistance.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Official eligibility criteria

Inclusion Criteria: * Subjects must be on a stable dose of guideline-directed medications for Heart Failure (HF). * Patients will have an established diagnosis of HF before the screening visit, documented by an acceptable imaging modality in the last 6 months. * Age = 18-80 y * Body Mass Index (BMI) =23-38 kg/m2 * Glycated hemoglobin (HbA1c) = 6.0-10.0% * Blood Pressure (BP) \< 145/85 mmHg * Estimated Glomerular Filtration Rate (eGFR) \> 30 ml/min•1.73 m2 * For women of child-bearing age (WOCBA) willingness to use contraception, if applicable. Exclusion Criteria: * Patients treated with Sodium-Glucose Transport Protein (SGLT2i's) or medications that may impair heart function or acutely worsen glycemic control will be excluded. * Pregnancy, lactation, or plans to become pregnant. A negative pregnancy test will be performed before each Magnetic resonance imaging (MRI) study to assess current status. * Allergy/sensitivity to study drugs or their ingredients. * Current drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements. * Inability or unwillingness of individual or legal guardian/representative to give written informed consent. * Subjects with a history of cancer (except basal or squamous cell cancer that has been resolved/remission for 5 years) * Cardiovascular event within the last 3 months * Major organ or metabolic diseases, or physical limitations that will not allow the subject to complete the study.
