A Study of the Effect of Dapagliflozin on Symptoms and Biomarkers in Diabetes Patients with Heart Failure


About this study

The primary purpose of this study is to evaluate the impact of dapagliflozin, as compared with placebo, on heart failure disease-specific biomarkers, symptoms, health status, and quality of life in patients who have type 2 diabetes and chronic heart failure with reduced systolic function.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

  2. Hemoglobin A1c of 6.5-11.0% at enrollment
  3. Established diagnosis of NYHA Class II or Class III heart failure (LVEF≤40% due to either ischemic or non-ischemic etiology) with reduced systolic function for at least 16 weeks prior to enrollment
  4. No change in diuretic management for at least 2 weeks prior to enrollment
  5. BNP ≥125 pg/mL and/or NTproBNP ≥ 600 pg/mL at enrollment

Exclusion Criteria:

  2. Estimated glomerular filtration rate (eGFR) < 45 at enrollment
  3. Hospitalization for heart failure within the 60 days prior to enrollment
  4. Admission for an acute coronary syndrome (ST-elevation MI, non-ST-elevation MI, or unstable angina), percutaneous coronary intervention, or cardiac surgery within the 60 days prior to enrollment
  5. Admission for cardiac resynchronization therapy (CRT) within 90 days prior to the screening visit
  6. Planned cardiovascular revascularization (percutaneous intervention or surgical) or major cardiac surgery (coronary artery bypass grafting, valve replacement, ventricular assist device, cardiac transplantation, or any other surgery requiring thoracotomy) within the 90 days after enrollment
  7. Patients who are volume depleted based upon physical examination at the time of enrollment
