A Study to Evaluate Dapagliflozin to Improve the LIVEs of Patients With PReserved Ejection Fraction Heart Failure

Overview

About this study

The purpose of this international study is to evaluate the effect of dapagliflozin 10 mg versus placebo in HFpEF patients, given once daily in addition to background regional standard of care therapy, including treatments to control co-morbidities, in reducing the composite of CV death or heart failure events.

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.

Inclusion Criteria:

  • Provision of signed informed consent prior to any study specific procedures.
  • Male or female patients age ≥ 40 years.
  • Documented diagnosis of symptomatic heart failure (NYHA class II-IV) at enrolment, and a medical history of typical symptoms/signs of heart failure ≥ 6 weeks before enrolment with at least intermittent need for diuretic treatment.
  • Left Ventricular Ejection Fraction (LVEF) > 40% and evidence of structural heart disease (e.g., left ventricular hypertrophy or left atrial enlargement ) documented by the most recent echocardiogram, and/or cardiac MR within the last 12 months prior to enrolment. For patients with prior acute cardiac events or procedures that may reduce LVEF; e.g., as defined in exclusion criterion 6, qualifying cardiac imaging assessment at least 12 weeks following the procedure/event is required.
    • NB: Patients with known heart failure but without a recent (≤ 12 months) assessment of left ventricular (LV) function and left chambers structure will undergo a local echocardiogram during the enrolment period.
  • NT-pro BNP ≥ 300 pg/ml at Visit 1 for patients without ongoing atrial fibrillation/flutter. If ongoing atrial fibrillation/flutter at Visit 1, NT-pro BNP must be ≥ 600 pg/mL.
  • Patients may be ambulatory, or hospitalized; patients must be off intravenous heart failure therapy (including diuretics) for at least 12 hours prior to enrolment and 24 hours prior to randomisation.

Exclusion Criteria:

  • Receiving therapy with an SGLT2 inhibitor within 4 weeks prior to randomisation or previous intolerance to an SGLT2 inhibitor.
  • Type 1 diabetes mellitus (T1D).
  • eGFR < 25 mL/min/1.73 m^2 (CKD-EPI formula) at Visit 1.
  • Systolic blood pressure (BP) < 95 mmHg on 2 consecutive measurements at 5-minute intervals, at Visit 1 or at Visit 2.
  • Systolic BP≥ 160 mmHg if not on treatment with ≥ 3 blood pressure lowering medications or ≥ 180 mmHg irrespective of treatments, on 2 consecutive measurements at 5-minute intervals, at Visit 1 or at Visit 2.
  • MI, unstable angina, coronary revascularization (percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)), ablation of atrial flutter/fibrillation, valve repair/replacement within 12 weeks prior to enrolment. Before enrolment, these patients must have their qualifying echocardiography and/or cardiac MRI examination at least 12 weeks after the event.
  • Planned coronary revascularization, ablation of atrial flutter/fibrillation and valve repair/replacement.
  • Stroke or transient ischemic attack (TIA) within 12 weeks prior to enrollment.
  • Probable alternative or concomitant diagnoses which in the opinion of the investigator could account for the patient's HF symptoms and signs (e.g., anaemia, hypothyroidism).
  • Body mass index > 50 kg/m^2.
  • Primary pulmonary hypertension, chronic pulmonary embolism, severe pulmonary disease including COPD (i.e., requiring home oxygen, chronic nebulizer therapy or chronic oral steroid therapy, or hospitalisation for exacerbation of COPD requiring ventilatory assist within 12 months prior to enrolment).
  • Previous cardiac transplantation, or complex congenital heart disease. Planned cardiac resynchronisation therapy.
  • HF due to any of the following: known infiltrative cardiomyopathy (e.g., amyloid, sarcoid, lymphoma, endomyocardial fibrosis), active myocarditis, constrictive pericarditis, cardiac tamponade, known genetic hypertrophic cardiomyopathy or obstructive hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D), or uncorrected primary valvular disease.
  • A life expectancy of less than 2 years due to any non-cardiovascular condition, based on investigator's clinical judgement.
  • Inability of the patient, in the opinion of the investigator, to understand and/or comply with study medications, procedures and/or follow-up OR any conditions that, in the opinion of the investigator, may render the patient unable to complete the study.
  • Active malignancy requiring treatment (with the exception of basal cell or squamous cell carcinomas of the skin).
  • Acute or chronic liver disease with severe impairment of liver function (e.g., ascites, oesophageal varices, coagulopathy).
  • Women of child-bearing potential (i.e., those who are not chemically or surgically sterilised or post-menopausal) not willing to use a medically accepted method of contraception considered reliable in the judgment of the investigator OR who have a positive pregnancy.
  • test at randomisation OR who are breast-feeding.
  • Involvement in the planning and/or conduct of the study (applies to both AstraZeneca personnel and/or personnel at the study site).
  • Previous randomisation in the present study.
  • Participation in another clinical study with an IP or device during the last month prior to enrolment.
