- Change from baseline in Kansas-City Cardiomyopathy Questionnaire-Total Symptom Score (KCCQ-TSS) at Week16 (higher scores represent less HF symptom frequency and burden). [ Time Frame: At baseline and at Week16 ]
To determine whether dapagliflozin is superior to placebo in patients with chronic heart failure with the New York Heart Association (NYHA) Functional Class II-IV (range I-IV, higher class represents worse functional class) and reduced ejection fraction (LVEF≤40%) [HFrEF] in:
- reducing patient-reported HF symptoms
- reducing patient-reported physical limitation
- improving exercise capacity
- Change from baseline in Kansas-City Cardiomyopathy Questionnaire-Physical Limitation Score (KCCQ-PLS) at Week16 (higher scores represent less physical limitation due to HF) [ Time Frame: At baseline and at Week16 ]
To determine whether dapagliflozin is superior to placebo in patients with chronic heart failure with the New York Heart Association (NYHA) Functional Class II-IV (range I-IV, higher class represents worse functional class) and reduced ejection fraction (LVEF≤40%) [HFrEF] in:
- reducing patient-reported HF symptoms
- reducing patient-reported physical limitation
- improving exercise capacity
- Change from baseline in 6-minute walk distance (6MWD) at Week16 (larger distances represent better functional capacity). [ Time Frame: At baseline and at Week16 ]
To determine whether dapagliflozin is superior to placebo in patients with chronic heart failure with the New York Heart Association (NYHA) Functional Class II-IV (range I-IV, higher class represents worse functional class) and reduced ejection fraction (LVEF≤40%) [HFrEF] in:
- reducing patient-reported HF symptoms
- reducing patient-reported physical limitation
- improving exercise capacity
- Change from baseline at the end of the study in the total time spent in light to vigorous physical activity, as assessed using a wearable activity monitor (accelerometer). [ Time Frame: From baseline until the week starting at Week14. ]To determine whether dapagliflozin is superior to placebo in increasing time spent non-sedentary, evaluated in a subset of at least 100 patients

Patients should receive background standard of care as described below: All HFrEF patients should be treated according to locally recognised guidelines on standard of care treatment with both drugs and devices, as appropriate. Guideline-recommended medications should be used at recommended doses unless contraindicated or not tolerated. Therapy should have been individually optimised and stable for ≥4 weeks (this does not apply to diuretics) before visit 1 and include (unless contraindicated or not tolerated):
- an ACE inhibitor, or ARB or sacubitril/valsartan and
- a beta-blocker and
- if considered appropriate by the patient's treating physician; a mineral corticoid receptor antagonis
- 6MWD≥100 metres and ≤425 metres at enrolment and randomization.
Exclusion Criteria:
- Presence of any condition that precludes exercise testing
- Participation in a structured exercise training programme in the 1 month prior to screening or planned to start during the trial
- Receiving therapy with an SGLT2 inhibitor within 4 weeks prior to enrolment or previous intolerance of an SGLT2 inhibitor

- eGFR <25 mL/min/1.73 m2 (CKD-EPI formula) at enrolment, unstable or rapidly progressing renal disease at time of randomisation
- Systolic BP <95 mmHg on 2 consecutive measurements
- Systolic BP ≥160 mmHg if not on treatment with ≥3 blood pressure lowering medications or ≥180 mmHg irrespective of treatments, on 2 consecutive measurements
- Current acute decompensated HF or hospitalisation due to decompensated HF <4 weeks prior to enrolment
- MI, unstable angina, coronary revascularization ablation of atrial flutter/fibrillation, valve repair/replacement, implantation of a cardiac resynchronization therapy device within 12 weeks prior to enrolment or planned to undergo any of these operations after randomization.
- Stroke or transient ischemic attack within 12 weeks prior to enrolment.
- Primary pulmonary hypertension, chronic pulmonary embolism, severe pulmonary disease including COPD.
