Heart Failure
EMPEROR-Reduced (NCT03057977) was a double-blind study conducted in patients with chronic heart failure (New York Heart Association [NYHA] functional class II-IV) with left ventricular ejection fraction (LVEF) ≤40% to evaluate the efficacy and safety of JARDIANCE as adjunct to standard of care heart failure therapy.
Of 3730 patients, 1863 were randomized to JARDIANCE 10 mg and 1867 to placebo and were followed for a median of 16 months. The mean age of the study population was 67 years (range: 25 to 94 years) and 76% were men, 24% were women, and 27% were 75 years of age or older. Approximately 71% of the study population were White, 18% Asian and 7% Black or African American. At baseline, 50% of the patients had type 2 diabetes mellitus.
At randomization, 75% of patients were NYHA class II, 24% were class III and 0.5% were class IV. The mean LVEF was 28%. At baseline, the mean eGFR was 62 mL/min/1.73 m
2 and the median urinary albumin to creatinine ratio (UACR) was 22 mg/g. Approximately half of the patients (52%) had eGFR equal to or above 60 mL/min/1.73 m
2, 24% had eGFR 45 to less than 60 mL/min/1.73 m
2, 19% had eGFR 30 to less than 45 mL/min/1.73 m
2 and 5% had eGFR 20 to less than 30 mL/min/1.73 m
2.
At baseline, 88% of patients were treated with angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARB), or angiotensin receptor-neprilysin inhibitors (ARNI), 95% with beta-blockers, 71% with mineralocorticoid receptor antagonists (MRA), and 95% with diuretics.
The primary endpoint was the time to first event of either cardiovascular death (CV) or hospitalization for heart failure (HHF). First and recurrent HHF was assessed as a key secondary endpoint.
JARDIANCE was superior in reducing the risk of the primary composite endpoint of cardiovascular death or hospitalization for heart failure compared with placebo, mostly through a reduction in hospitalization for heart failure. JARDIANCE reduced the risk of first and recurrent HHF (see
Table 14 and
Figures 7 and
8).

The results of the primary composite were generally consistent across the pre-specified subgroups (see
Figure 9).
Treatment Effects for the Primary Composite Endpoint (Cardiovascular Death and Hospitalization for Heart Failure) Subgroup Analysis (EMPEROR-Reduced)
LVEF >30%: Includes both above and below the median NT-proBNP. To be eligible for inclusion, patients with an LVEF >30% were required to meet a higher NT-proBNP threshold than those with LVEF ≤30%, unless they additionally had a history of HHF within the past 12 months.
EMPEROR-Preserved (NCT03057951) was a double-blind study conducted in patients with chronic heart failure NYHA Class II-IV with LVEF >40% to evaluate the efficacy and safety of JARDIANCE as adjunct to standard of care therapy.
Of 5988 patients, 2997 were randomized to JARDIANCE 10 mg and 2991 to placebo and were followed for a median of 26 months. The mean age of the study population was 72 years (range: 22 to 100 years) and 55% were men, 45% were women, and 43% were 75 years of age or older. Approximately 76% of the study population were White, 14% Asian and 4% Black or African American.
At randomization, 82% of patients were NYHA class II, 18% were class III and 0.3% were class IV. The EMPEROR-Preserved study population included patients with a LVEF <50% (33.1%), with a LVEF 50 to <60% (34.4%) and a LVEF ≥60% (32.5%). At baseline, the mean eGFR was 61 mL/min/1.73 m
2 and the median urinary albumin to creatinine ratio (UACR) was 21 mg/g. Approximately half of the patients (50%) had eGFR equal to or above 60 mL/min/1.73 m
2, 26% had eGFR 45 to less than 60 mL/min/1.73 m
2, 19% had eGFR 30 to less than 45 mL/min/1.73 m
2, and 5% had eGFR 20 to less than 30 mL/min/1.73 m
2.
At baseline, 81% of patients were treated with ACE inhibitors, ARBs, or ARNI, 86% with beta-blockers, 38% with MRAs, and 86% with diuretics.
The primary endpoint was the time to first event of either CV death or HHF. First and recurrent HHF was assessed as a key secondary endpoint.
JARDIANCE was superior in reducing the risk of the primary composite endpoint compared with placebo, mostly through a reduction in hospitalization for heart failure. JARDIANCE reduced the risk of first and recurrent HHF (see
Table 15 and Figures
10 and
11).
