LCZ696 in Advanced Heart Failure - LIFE
Contribution To Literature:
The LIFE trial showed that combination sacubitril/valsartan did not reduce NT-proBNP or clinical outcomes among patients with advanced HFrEF and comorbidities.
The goal of the trial was to assess the efficacy and safety of sacubitril/valsartan compared with valsartan in patients with advanced heart failure with reduced ejection fraction (HFrEF).
Eligible patients were randomized in a 1:1 fashion to either sacubitril/valsartan (starting dose 24/26 mg or 49/51 mg BID, uptitrated to 97/103 mg BID if tolerated after 4 weeks) (n = 167), or valsartan (starting dose 40 or 80 mg BID, uptitrated to 160 mg BID if tolerated) (n = 168).
- Total screened: 462
- Total number of enrollees: 335
- Duration of follow-up: 24 weeks
- Mean patient age: 60 years
- Percentage female: 27%
- NYHA class IV symptomatology in previous 3 months
- Receiving guideline-directed medical therapy (GDMT) for HF for ≥3 months and/or intolerant to GDMT
- Left ventricular EF (LVEF) ≤35%
- B-type natriuretic peptide (BNP) ≥250 pg/ml or N-terminal pro-BNP (NT-proBNP) ≥800 pg/ml
- Systolic blood pressure ≥90 mm Hg
- ≥1 additional objective finding of advanced HF
- Current inotropic therapy/use of inotropes within 6 months
- ≥1 HF hospitalization within 6 months
- LVEF ≤25% within 12 months
- Decreased peak VO2 within 12 months
- 6-minute walk test distance <300 meters within 3 months
Other salient features/characteristics:
- White race: 60%
- LVEF: 20%
- Systolic blood pressure: 113 mm Hg
- Baseline medications: beta-blockers: 78%, loop diuretics: 93%, mineralocorticoid antagonists: 57%
The primary outcome, area under the curve (AUC) for the proportional change in the ratio of NT-proBNP to baseline, for sacubitril/valsartan vs. valsartan, was p = 0.45.
Secondary outcomes for sacubitril/valsartan vs. valsartan:
- Days alive, out of hospital, or free from HF events: 103.2 vs. 111.2 days (p = 0.45)
- CV death or hospitalization for HF: hazard ratio 1.32, 95% confidence interval 0.86-2.03 (p = 0.20)
- Hypotension: 17% vs. 12% (p = 0.16)
- Hyperkalemia: 17% vs. 9% (p = 0.035)
The results of this trial indicate that the combination sacubitril/valsartan did not reduce NT-proBNP or clinical outcomes among patients with advanced HFrEF and comorbidities. These data add to the available literature with angiotensin receptor-neprilysin inhibitors (ARNIs).
