EMPEROR-HF: A phase III randomised, double-blind trial to evaluate efficacy and safety of once daily empagliflozin 10 mg compared to placebo, in patients with chronic Heart Failure with reduced Ejection Fraction (HFrEF)
Age: 18 - 45 years
Healthy Subjects: No
Recruitment Status: Recruiting
Start Date: October 12, 2018
End Date: December 12, 2018
Chronic heart failure (HF) is a progressive syndrome characterized by the inability of the heart to provide adequate blood supply to meet the metabolic demand of different tissues or to be able to do so only at the expense of elevated left ventricle filling pressure. HF is a prevalent disease affecting an estimated 26 million people worldwide. About 25 to 45% of patients with HF have concomitant type 2 diabetes mellitus (T2DM), and nearly 15-25% has borderline diabetes (pre-diabetes), indicating a potential link between the HF syndromes and glucometabolic disturbances.
Despite the current standard of care for treatment of HFrEF such as medical therapy [angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARB), beta blockers, mineralocorticoid receptor antagonists (MRA), ivabradine and angiotensin receptor blocker-neprilysin inhibitor (ARNI)] or device therapy the mortality and morbidity remains high in HF patients.
Empagliflozin is an orally available inhibitor of the renal dependent glucose co-transporter 2 (SGLT-2) indicated for, reduction of blood glucose in patients with T2DM by promoting urinary glucose excretion. It also reduces blood pressure, arterial stiffness and measures of the myocardial workload, likely through various mechanisms, as well as improving other CV risk factors (uric acid, visceral fat mass, albuminuria).
The objective of this event-driven trial is to demonstrate superiority of empagliflozin 10 mg versus placebo on top of guideline-directed medical therapy in patients with symptomatic, chronic HF and reduced ejection fraction (LVEF ≤ 40%).
1. Age ≥ 18 years at screening. For Japan only: Age ≥ 20 years at screening
2. Male or female patients. WOCBP must be ready and able to use highly effective methods of birth control per ICH M3 (R2) [R09-1400] 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
3. Patients with chronic HF diagnosed for at least 3 months before Visit 1, and currently in HF NYHA class II-IV
4. Chronic HF with reduced EF defined as LVEF ≤ 40% per local reading (obtained under stable condition by echocardiography, radionuclide ventriculography, invasive angiography, MRI or CT). A historical LVEF may be used if it was measured within 6 months prior to visit 1 or the LVEF may be measured after study consent has been obtained. The LVEF must be documented in an official report prior to randomization.
5. In addition to LVEF ≤ 40%, patients must have at least one of the following evidence of HF:

b) If EF ≥31% to ≤35%: Elevated NT-proBNP at Visit 1 ≥1000 pg/ml for patients without AF, OR ≥2000 pg/ml for patients with AF, analysed at the Central Laboratory,
c) If EF≤30%: Elevated NT-proBNP at Visit 1 ≥600 pg/ml for patients without AF, OR ≥1200 pg/ml for patients with AF, analysed at the Central Laboratory
d) For EF ≤ 40% and documented HHF within 12 months prior to visit 1, elevated NT-proBNP at Visit 1 ≥ 600 pg/ml for patients without AF and ≥ 1200 pg/ml for patients with AF, analysed at the Central Laboratory.
6. Appropriate dose of medical therapy for HF (such as ACEi, ARB, β-blocker, oral diuretics, MRA, ARNI, ivabradine) consistent with prevailing local and international CV guidelines, stable for at least 1 week prior to Visit 1 and during screening period until Visit 2 (Randomisation) with the exception of diuretics stable for only one week prior to Visit 2 to control symptoms. The investigator must document in the source documents the reason why patient not on target dose per local guidelines
7. Appropriate use of medical devices such as cardioverter defibrillator (ICD) or a cardiac resynchronization therapy (CRT) consistent with prevailing local or international CV guidelines (refer also to exclusion #29)
