- Time to the first occurrence of any of the components of this composite: 1) CV death; 2) Hospitalisation for HF; 3) Urgent HF visit (e.g., emergency department or outpatient visit) [ Time Frame: Up to approximately 39 months ]
To determine whether dapagliflozin is superior to placebo, when added to standard of care, in reducing the composite of CV death and HF events (hospitalisation for HF or urgent HF visit) in patients with HF and preserved systolic function in
- full study population
- subpopulation with LVEF <60%
- Total number of HF events (first and recurrent) and CV death [ Time Frame: up to approximately 39 months ]
To determine whether dapagliflozin is superior to placebo in reducing the total number of HF events (hospitalisation for HF or urgent HF visit) and CV death in
- full study population
- subpopulation with LVEF <60%
- Change from baseline in the total symptom score (TSS) of the KCCQ at 8 months [ Time Frame: Evaluated at 8 months after randomization ]To determine whether dapagliflozin is superior to placebo in improving Patient Reported Outcomes measured by KCCQ
- Time to the occurrence of CV death [ Time Frame: up to approximately 39 months ]To determine whether dapagliflozin is superior to placebo in reducing CV death
- Time to the occurrence of death from any cause [ Time Frame: up to approximately 39 months ]To determine whether dapagliflozin is superior to placebo in reducing all-cause mortality
- Serious adverse events (SAEs), adverse events leading to treatment discontinuation (DAEs), amputations, adverse events (AEs) leading to amputation and potential risk factor AEs for amputations affecting lower limbs [ Time Frame: up to approximately 39 months ]Safety: To evaluate the safety and tolerability of dapagliflozin compared to placebo in patients with HFpEF

Ages Eligible for Study: | 40 Years to 130 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
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 (i.e. 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.
- Elevated NT-pro BNP levels.
- Both ambulatory and hospitalised patients may be enrolled and randomised. Patients currently hospitalised for HF, must be off intravenous HF medications for at least 24 before randomisation.
Further details regarding inclusion criteria 4-6 may apply.
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 m2 (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 enrolment.
- 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/m2.
