A Study That Looks at the Function of the Heart in Patients With Heart Failure Who Take Empagliflozin

Inclusion Criteria

• •Chronic heart failure diagnosed at least 3 months before informed consent
• •NYHA class II-IV at screening
• •Age ≥ 18 years at screening
• •Male or female patients. Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the patient information.
• •Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial
• •Cohort A Heart Failure with Reduced Ejection Fraction (HFrEF)
• •Left ventricular ejection fraction (LVEF) ≤ 40% as measured by ECHO at screening
• •The following signs of heart failure;
• •* Elevated NT-proBNP (\>125 pg/mL) at screening in patient without atrial fibrillation (AF)
• •* Elevated NT-proBNP (\>600 pg/mL) at screening in patient with AF
• •Appropriate dose of medical therapy for HF (such as ACEi, ARB, β-blocker, oral diuretics, MRA, ARNI, ivabradine) consistent with prevailing local and international HF guidelines, stable for at least one week prior to Visit 1 and during screening period until Visit 2 (Randomisation) with the exception of diuretics which must be stable for at least one week prior to Visit 2 to control symptoms. If required, the investigator must document in the source documents the reason why the patient is not on the target dose per local guidelines.
• •Cohort B Heart Failure with Preserved Ejection Fraction (HFpEF)
• •Left ventricular ejection fraction (LVEF) ≥ 50% as measured by ECHO at screening and no previous measurement of LVEF ≤ 40%.
• •The following combined signs of heart failure;
• •* Structural heart disease (LA enlargement \[LAVI \>34 mL/m2\] and/or LVH \[LVMI ≥ 115 g/m2 for males and ≥ 95 g/m2 for females\]) by ECHO at screening or within 3 months prior to informed consent AND
• •* NT-proBNP \> 125pg/mL at screening in patient without AF or NT-pro-BNP \> 600 pg/mL in patient with AF
• •Oral diuretics, if prescribed, should be stable for at least one week prior to Visit 1 and during screening period until Visit 2 (Randomisation).
• •Symptomatic hypotension and/or a SBP \< 100 mmHg at Screening
• •Atrial fibrillation which is uncontrolled in the opinion of the investigator
• •Untreated ventricular arrhythmia with syncope documented within the 3 months prior to informed consent in patients without ICD
• •Diagnosis of cardiomyopathy induced by chemotherapy or peripartum within the 12 months prior to informed consent
• •Symptomatic bradycardia or second or third degree heart block in need of a pacemaker after adjusting beta-blocker therapy or any other negative inotropic agents, if appropriate
• •Chronic pulmonary disease requiring home oxygen, oral steroid therapy or hospitalisation for exacerbation within 12 months prior to informed consent, or significant chronic pulmonary disease in the Investigator's opinion, or primary pulmonary arterial hypertension
• •Indication of liver disease, defined by serum levels of either ALT (SGPT), AST (SGOT),or alkaline phosphatase above 3 x upper limit of normal (ULN) as determined at screening
• •Impaired renal function, defined as estimated Creatinine Clearance \< 30 mL/min (using Cockcroft-Gault formula) or requiring dialysis, as determined at screening
• •Haemoglobin \< 10 g/dL at screening
• •Type 1 Diabetes Mellitus (T1DM)
• •History of ketoacidosis
• •Major surgery (major according to the investigator's assessment) performed within 3 months prior to informed consent, or scheduled major elective surgery (e.g. hip replacement) within 3 months after Visit 1
• •Gastrointestinal (GI) surgery or GI disorder that could interfere with absorption of trial medication in the investigator's opinion
• •Any documented active or suspected malignancy or history of malignancy within 6 months prior to informed consent, except appropriately treated basal cell carcinoma of the skin, in situ carcinoma of uterine cervix or low risk prostate cancer (patients with pretreatment PSA \<10 ng/mL, and biopsy Gleason score of ≤ 6 and clinical stage T1c or T2a)
• •Presence of any other disease than heart failure with a life expectancy of \<1 year in the investigator's opinion
• •Patients who must or wish to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial
• •Patients with requirement for treatment with empagliflozin according to local standard of care
• •Treatment with any SGLT-2 inhibitor or combined SGLT-1 and 2 inhibitor within 1 week prior to informed consent or during screening period until Visit 2 (Randomisation)
• •Currently enrolled in another investigational device or drug study, or less than 30 days between randomisation and ending another investigational device or drug study, or receiving other investigational treatment(s). Patients participating in a purely observational trial will not be excluded.
• •Known allergy or hypersensitivity to empagliflozin or other SGLT-2 inhibitors
• •Chronic alcohol or drug abuse or any condition that, in the investigator's opinion, makes them an unreliable trial subject or unlikely to complete the trial
• •Women who are pregnant, breastfeeding, or who plan to become pregnant while in the trial
• •Any clinical condition that would jeopardise patients safety while participating in this trial, or may prevent the subject from adhering to the trial protocol
