Efficacy and Safety of Sacubitril/Valsartan by Dose Level Achieved in the PIONEER-HF Trial.

ABSTRACT:

Objectives

This study sought to evaluate the efficacy and safety of sacubitril/valsartan according to dose level achieved in the PIONEER-HF (Comparison of Sacubitril/Valsartan Versus Enalapril on Effect on NT-proBNP in Patients Stabilized From an Acute Heart Failure Episode) trial.

Background

In patients hospitalized for acute decompensated heart failure (ADHF), in-hospital initiation and continuation of sacubitril/valsartan as compared with enalapril is well tolerated, achieves a greater reduction in N-terminal pro-B-type natriuretic peptide (NT-proBNP), and reduces the risk of cardiovascular death or rehospitalization for HF through 8 weeks. However, not all patients achieve the target dose of sacubitril/valsartan, and its efficacy and safety in such patients are of interest.

Methods

PIONEER-HF was a randomized, double-blind, active-controlled trial of sacubitril/valsartan versus enalapril in 881 patients stabilized during hospitalization for ADHF. Blinded study medication was administered for 8 weeks, with initial dosing selected based on the systolic blood pressure at randomization and titrated toward a target of sacubitril/valsartan 97/103 mg twice daily, or enalapril 10 mg twice daily, with an algorithm based on systolic blood pressure and the investigator's assessment of tolerability.

Results

At 4 weeks, 199 (55%) patients allocated to sacubitril/valsartan and 211 (60%) patients allocated to enalapril were dispensed the target dose. Baseline characteristics were similar in the 2 treatment groups within each dose level. There was no heterogeneity across dose levels in the effect of sacubitril/valsartan on the reduction in NT-proBNP (p_interaction = 0.69), the reduction in cardiovascular death or rehospitalization for heart failure (p_interaction = 0.42), or the pre-specified adverse events of special interest through 8 weeks.

Conclusions

In hemodynamically stabilized patients with ADHF, the efficacy and safety of sacubitril/valsartan are generally consistent across dose levels.

Project description:BackgroundIn patients stabilized during hospitalization for acute decompensated heart failure (HF), initiation of sacubitril/valsartan compared with enalapril decreased the risk of cardiovascular death or rehospitalization for HF without increasing the risk of adverse events. It is unknown whether potentially high-risk subpopulations have a similar risk-benefit profile.MethodsPIONEER-HF (Comparison of Sacubitril/Valsartan Versus Enalapril on Effect on NT-proBNP [N-terminal pro-B type natriuretic peptide] in Patients Stabilized From an Acute HF Episode) was a multicenter, randomized, double-blind trial of in-hospital initiation of sacubitril/valsartan (n=440) versus enalapril (n=441) in patients stabilized during hospitalization for acute decompensated HF. The composite of cardiovascular death or rehospitalization for HF was adjudicated. Safety outcomes included worsening renal function, symptomatic hypotension, and hyperkalemia. We evaluated heterogeneity in the effect of sacubitril/valsartan on these efficacy and safety outcomes in selected subgroups of clinical concern: patients with baseline systolic blood pressure ≤118 mm Hg (median; n=448), baseline NT-proBNP >2701 pg/mL (median; n=395), estimated glomerular filtration rate <60 mL/minute per 1.73 m2 (n=455), ≥1 additional hospitalization for HF within the prior year (n=343), admission to the ICU during the index hospitalization (n=96), inotrope use during the index hospitalization (n=68), and severe congestion (n=219).ResultsThe relative risk reduction in cardiovascular death or rehospitalization for HF with sacubitril/valsartan versus enalapril was consistent across all high-risk subgroups (P interaction=non-significant [NS] for each). The risks of worsening renal function, symptomatic hypotension, and hyperkalemia with sacubitril/valsartan versus enalapril were also consistent in each high- versus low-risk subgroup (P interaction=NS for each).ConclusionsIn high-risk subpopulations admitted for acute decompensated HF, treatment with sacubitril/valsartan after initial stabilization conferred a consistent reduction in cardiovascular death or rehospitalization for HF and was well tolerated.

Project description:BackgroundNatriuretic peptides are substrates of neprilysin; hence, B-type natriuretic peptide (BNP) concentrations rise with neprilysin inhibition. Thus, the clinical validity of measuring BNP in sacubitril/valsartan-treated patients has been questioned, and use of N-terminal pro-B-type natriuretic peptides (NT-proBNP) has been preferred and recommended.ObjectivesThe purpose of this study was to determine the prognostic performance of BNP measurements before and during treatment with sacubitril/valsartan.MethodsBNP and NT-proBNP were measured before and after 4 to 6 weeks, 8 to 10 weeks, and 9 months of treatment with sacubitril/valsartan in the PARADIGM-HF (Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) trial. We assessed the association of levels of these natriuretic peptides with the subsequent risk of cardiovascular death or hospitalization for HF.ResultsMedian BNP concentration (before treatment: 202 ng/l [Q1 to Q3: 126 to 335 ng/l]) increased to 235 ng/l (Q1 to Q3: 128 to 422 ng/l) after 8 to 10 weeks of treatment. BNP concentrations doubled in 141 (18%) patients and tripled in 49 (6%) patients during the first 8 to 10 weeks of sacubitril/valsartan. In contrast, such striking increases in NT-proBNP following the use of the neprilysin inhibitor were extremely rare. Treatment with sacubitril/valsartan caused a rightward shift in the distribution of BNP when compared with NT-proBNP, but both peptides retained their prognostic accuracy (C-statistics of 63% to 67% for BNP and C-statistics of 64% to 70% for NT-proBNP) with no difference between the 2 biomarkers. Increases in both BNP and NT-proBNP during 8 to 10 weeks of sacubitril/valsartan were associated with worse outcomes (p = 0.003 and p = 0.005, respectively).ConclusionsCirculating levels of BNP may increase meaningfully early after initiation of sacubitril/valsartan. In comparison, NT-proBNP is not a substrate of neprilysin inhibition, and thus may lead to less clinical confusion when measured within 8 to 10 weeks of drug initiation. However, during treatment, either biomarker predicts the risk of major adverse outcomes in patients treated with angiotensin receptor-neprilysin inhibitors.

Project description:BackgroundControversy has persisted over the clinical benefits of low-dose sacubitril/valsartan in patients with heart failure (HF).HypothesisLow-dose sacubitril/valsartan might also be effective and safe in HF patients.MethodsElectronic databases including PubMed, Ovid, and Cochrane Library were systematically retrieved from inception to August 5, 2021. Review manager 5.4 and Stata 15.1 were employed in this systematic review and meta-analysis. Key efficacy outcomes of interest included HF hospitalization, all-cause mortality, left ventricular ejection fraction (LVEF), N-terminal pro-B-type natriuretic peptide (NT-proBNP), together with New York Heart Association (NYHA) functional class. The safety outcome was systolic blood pressure (SBP). The grading of recommendations assessment, development, and evaluation approach was conducted to evaluate the quality of evidence for each outcome.ResultsA total of 1269 studies were screened and 9 real-world studies met the inclusion criteria were included in the meta-analysis, with 1697 participants. Compared with low-dose sacubitril/valsartan, high-dose sacubitril/valsartan significantly reduced the risk of HF hospitalization (odds ratio [OR]: 0.4, 95% confidence interval [CI]: 0.27-0.61, p < .0001) and the risk of all-cause mortality (OR: 0.23, 95% CI: 0.11-0.47, p < .0001). However, there were no appreciable differences in improvements of NYHA (OR: 0.59, 95% CI: 0.15-2.35, p = .45), changes of LVEF (mean difference [MD]: 2.73%, 95% CI: -2.24% to 7.7%, p = .28), changes of NT-proBNP (MD: 43.09, 95% CI: -28.41 to 114.59, p = .24) and changes of SBP (MD: 3.01, 95% CI: -4.62 to 10.64, p = .44) between groups with low-dose and high-dose sacubitril/valsartan.ConclusionsCompared with high-dose sacubitril/valsartan, low-dose sacubitril/valsartan was associated with increased risks of HF hospitalization and all-cause mortality. However, no distinct between-group differences in improvements of NYHA, changes of LVEF, changes of NT-proBNP and changes of SBP were observed.

Project description:BackgroundThe angiotensin-receptor neprilysin inhibitor (ARNI) sacubitril/valsartan was shown to be superior to the angiotensin receptor blocker (ARB) valsartan in terms of reversing heart failure classification (NYHA classification), reducing N-terminal pro-brain natriuretic peptide (NT-proBNP) level and cardiovascular mortality in many studies. Yet, the efficacy of ARNI did not come from patients with acute myocardial infarction (AMI).MethodsWe searched databases for research published from inception to July 29, 2022, that reported cardiac reverse remodeling (CRR) or security indices. Two reviewers independently screened literature, extracted data, and assessed the risk of bias. Nine studies enrolling 1,369 patients were included to perform a meta-analysis. There were 716 patients in the ARNI group and 653 in the ARB group.ResultsARNI outperformed ARBs in terms of CRR indices, with striking changes in left ventricular ejection fraction (EF) (MD: 4.12%, 95%CI: 2.36, 5.88, P < 0.0001), diameter (MD: -3.40 mm, 95%CI: -4.30, -2.94, P < 0.00001, I 2 = 0%) and left atrial diameter (MD: -2.41 mm, 95%CI: -3.85, -0.97, P = 0.001, I 2 = 0%), other indices there showed no significant improvements. The incidences of major adverse cardiac events (RR: 0.47, 95%CI: 0.34-0.65, P < 0.00001, I 2 = 0%), the heart failure (RR: 0.37, 95%CI: 0.23-0.61, P < 0.0001, I 2 = 0%), readmission (RR: 0.54, 95%CI: 0.36-0.80, P = 0.003, I 2 = 29%) in the sacubitril/valsartan group were lower than the ARB group, while the incidences of cardiac death (RR: 0.56, 95%CI: 0.28, 1.09, P = 0.09), the myocardial infarction (RR: 0.83, 95% CI: 0.39, 1.77, P = 0.63), adverse side effects (RR: 1.67, 95% CI: 0.89, 3.13, P = 0.11) showed no difference.ConclusionThis research indicated that early initiation of sacubitril/valsartan in patients after AMI was superior to ARBs in reducing the risks of major adverse cardiac events, heart failure, readmission, and enhancing left ventricular EF, decreasing diameter, left atrial diameter. As for the other outcomes (the incidences of cardiac death, myocardial infarction, and adverse side effects), sacubitril/valsartan demonstrated no obvious advantage over ARBs.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier [CRD42022307237].

Project description:AimsThe PARAGLIDE-HF trial demonstrated reductions in natriuretic peptides with sacubitril/valsartan compared with valsartan in patients with heart failure (HF) with mildly reduced or preserved ejection fraction who had a recent worsening HF event, but was not adequately powered to examine clinical outcomes. PARAGON-HF included a subset of PARAGLIDE-HF-like patients who were recently hospitalized for HF. Participant-level data from PARAGLIDE-HF and PARAGON-HF were pooled to better estimate the efficacy and safety of sacubitril/valsartan in reducing cardiovascular and renal events in HF with mildly reduced or preserved ejection fraction.Methods and resultsBoth PARAGLIDE-HF and PARAGON-HF were multicentre, double-blind, randomized, active-controlled trials of sacubitril/valsartan vs. valsartan in patients with HF with mildly reduced or preserved left ventricular ejection fraction (LVEF >40% in PARAGLIDE-HF and ≥45% in PARAGON-HF). In the pre-specified primary analysis, we pooled participants in PARAGLIDE-HF (all of whom were enrolled during or within 30 days of a worsening HF event) with a 'PARAGLIDE-like' subset of PARAGON-HF (those hospitalized for HF within 30 days). We also pooled the entire PARAGLIDE-HF and PARAGON-HF populations for a broader context. The primary endpoint for this analysis was the composite of total worsening HF events (including first and recurrent HF hospitalizations and urgent visits) and cardiovascular death. The secondary endpoint was the pre-specified renal composite endpoint for both studies (≥50% decline in estimated glomerular filtration rate from baseline, end-stage renal disease, or renal death). Compared with valsartan, sacubitril/valsartan significantly reduced total worsening HF events and cardiovascular death in both the primary pooled analysis of participants with recent worsening HF [n = 1088; rate ratio (RR) 0.78; 95% confidence interval (CI) 0.61-0.99; P = 0.042] and in the pooled analysis of all participants (n = 5262; RR 0.86; 95% CI: 0.75-0.98; P = 0.027). In the pooled analysis of all participants, first nominal statistical significance was reached by Day 9 after randomization, and treatment benefits were larger in those with LVEF ≤60% (RR 0.78; 95% CI 0.66-0.91) compared with those with LVEF >60% (RR 1.09; 95% CI 0.86-1.40; Pinteraction = 0.021). Sacubitril/valsartan was also associated with lower rates of the renal composite endpoint in the primary pooled analysis [hazard ratio (HR) 0.67; 95% CI 0.43-1.05; P = 0.080] and the pooled analysis of all participants (HR 0.60; 95% CI 0.44-0.83; P = 0.002).ConclusionIn pooled analyses of PARAGLIDE-HF and PARAGON-HF, sacubitril/valsartan reduced cardiovascular and renal events among patients with HF with mildly reduced or preserved ejection fraction. These data provide support for use of sacubitril/valsartan in patients with HF with mildly reduced or preserved ejection fraction, particularly among those with an LVEF below normal, regardless of care setting.
