Project description:Sacubitril/valsartan (LCZ696) is indicated for the treatment of patients with heart failure and reduced ejection fraction (HFrEF). Since patients with HFrEF may receive sacubitril/valsartan and sildenafil, both increasing cyclic guanosine monophosphate, the present study evaluated the pharmacokinetic and pharmacodynamic drug interaction potential between sacubitril/valsartan and sildenafil. In this open-label, three-period, single sequence study, patients with mild-to-moderate hypertension (153.8 ± 8.2 mmHg mean systolic blood pressure (SBP)) received a single dose of sildenafil 50 mg, sacubitril/valsartan 400 mg once daily for 5 days, and sacubitril/valsartan and sildenafil coadministration. When coadministered with sildenafil, the AUC and Cmax of valsartan decreased by 29% and 39%, respectively. Coadministration of sacubitril/valsartan and sildenafil resulted in a greater decrease in BP (-5/-4/-4 mmHg mean ambulatory SBP/DBP/MAP (mean arterial pressure)) than with sacubitril/valsartan alone. Both treatments were generally safe and well tolerated in this study; however, the additional BP reduction suggests that sildenafil should be administered cautiously in patients receiving sacubitril/valsartan.

Project description:Importance:Health-related quality of life (HRQL) of patients with heart failure is markedly reduced compared with that in patients with other chronic diseases, demonstrating substantial limitations in physical and social activities. In the Prospective Comparison of ARNI With an ACE-Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure (PARADIGM-HF) trial, sacubitril/valsartan improved overall HRQL compared with enalapril, as determined by the Kansas City Cardiomyopathy Questionnaire (KCCQ). Objective:To examine the effects of sacubitril/valsartan on physical and social activities. Design, Setting, and Participants:The PARADIGM-HF trial was a randomized, double-blind, active treatment-controlled clinical trial performed from December 8, 2009, to March 31, 2014, in 8399 patients with New York Heart Association class II to IV disease and a left ventricular ejection fraction of 40% or less at 1043 centers in 38 countries. Data analysis was performed from August 1, 2017, to December 25, 2017. Interventions:Sacubitril/valsartan, 200 mg twice daily, or enalapril, 10 mg twice daily. Main Outcomes and Measures:Patients completed HRQL assessments using the KCCQ at randomization, 4-month, 8-month, and annual visits. The effect of sacubitril/valsartan on components of the physical and social limitation sections of the KCCQ at 8 months and longitudinally and related biomarkers and clinical outcomes were studied. Results:At baseline, 7618 of 8399 patients (90.7%) (mean [SD] age, 64 [11] years; 5987 [78.6%] male and 1631 [21.4%] female) completed the initial KCCQ assessment. Patients reported the greatest limitations at baseline in jogging and sexual relationships. Patients receiving sacubitril/valsartan had significantly better adjusted change scores in most physical and social activities at 8 months and during 36 months compared with those receiving enalapril. The largest improvement over enalapril was in household chores (adjusted change score difference, 2.35; 95% CI, 1.19-3.50; P?<?.001) and sexual relationships (adjusted change score difference, 2.72; 95% CI, 0.97-4.46; P?=?.002); both persisted through 36 months (overall change score difference, 1.69 [95% CI, 0.78-2.60], P?<?.001; and 2.36 [95% CI, 1.01-3.71], P?=?.001, respectively). Conclusions and Relevance:In patients with heart failure with reduced ejection fraction, sacubitril/valsartan significantly improved nearly all KCCQ physical and social activities compared with enalapril, with the largest responses in household chores and sexual relationships. In addition to reduced likelihood of cardiovascular death, all-cause mortality, and heart failure hospitalization, sacubitril/valsartan may improve limitations in common activities in these patients.

Project description:AIMS:Elevated serum uric acid concentration (SUA) has been associated with an increased risk of cardiovascular disease, but this may be due to unmeasured confounders. We examined the association between SUA and outcomes as well as the effect of sacubitril/valsartan on SUA in patients with heart failure with reduced ejection fraction (HFrEF) in PARADIGM-HF. METHODS AND RESULTS:The association between SUA and the primary composite outcome of cardiovascular death or heart failure (HF) hospitalization, its components, and all-cause mortality was examined using Cox regression analyses among 8213 patients using quintiles (Q1-Q5) of SUA adjusted for baseline prognostic variables including estimated glomerular filtration rate (eGFR), diuretic dose, and log N-terminal pro-brain natriuretic peptide. Change in SUA from baseline over 12 months was also evaluated in each treatment group. Patients in Q5 (SUA ≥8.6 mg/dL) compared with Q1 (<5.4 mg/dL) were younger (62.8 vs. 64.2 years), more often male (88.7% vs. 63.1%), had lower systolic blood pressure (119 vs. 123 mmHg), lower eGFR (57.4 vs. 76.6 mL/min/1.73 m2 ), and greater diuretic use. Higher SUA was associated with a higher risk of the primary outcome (adjusted hazard ratios) Q5 vs. Q1 = 1.28 [95% confidence intervals (1.09-1.50), P = 0.003], cardiovascular death [1.44 (1.11-1.77), P = 0.001], HF hospitalization [1.37 (1.11-1.70), P = 0.004], and all-cause mortality [1.36 (1.13-1.64), P = 0.001]. Compared with enalapril, sacubitril/valsartan reduced SUA by 0.24 (0.17-0.32) mg/dL over 12 months (P < 0.0001). Sacubitril/valsartan improved outcomes, irrespective of SUA concentration. CONCLUSION:Serum uric acid concentration was an independent predictor of worse outcomes after multivariable adjustment in patients with HFrEF. Compared with enalapril, sacubitril/valsartan reduced SUA and improved outcomes irrespective of SUA.

Project description:AIMS:Circulating high-sensitivity cardiac troponin (hsTn) and soluble ST2 (sST2) reflect myocardial stress in patients with heart failure (HF). Production of cyclic guanosine 3'5' monophosphate (cGMP) in response to activation of natriuretic peptide receptors reduces cardiac afterload and preload. We assessed the effects of sacubitril/valsartan on these biomarkers in patients with reduced ejection fraction and acute decompensated HF (ADHF). METHODS AND RESULTS:PIONEER-HF was a randomized, double-blind trial of sacubitril/valsartan vs. enalapril in hospitalized patients with ADHF following haemodynamic stabilization. We measured circulating hsTnT, sST2, and urinary cGMP at baseline, 1, 2 (sST2, cGMP), 4, and 8?weeks (n?=?694 with all baseline biomarkers). Ratios of geometric means (timepoint/baseline) were determined and compared as a ratio for sacubitril/valsartan vs. enalapril. Compared with enalapril, sacubitril/valsartan led to a significantly greater decline in hsTnT and sST2. This effect emerged as early as 1?week for sST2 and was significant for both at 4?weeks with a 16% greater reduction in hsTnT (P?<?0.001) and 9% greater reduction in sST2 (P?=?0.0033). Serial urinary cGMP increased with sacubitril/valsartan compared with enalapril (P?<?0.001, 1?week). The significant differences between treatment groups for each biomarker were sustained at 8?weeks. In an exploratory multivariable-adjusted analysis of cardiovascular death or HF-rehospitalization, the concentrations of hsTnT, sST2 at week 1 were significantly associated with subsequent outcome. CONCLUSION:Biomarkers of myocardial stress are elevated in patients with ADHF and associated with outcome. Compared with enalapril, sacubitril/valsartan reduces myocardial injury and haemodynamic stress as reflected by biomarkers, with an onset that is apparent within 1-4?weeks.

Project description:<h4>Objectives</h4>To determine efficacy and safety of sacubitril/valsartan compared with enalapril in Indian patients of PARADIGM-HF trial.<h4>Methods</h4>A randomized, double-blind, active-controlled, phase III sub-study (NCT01035255) was conducted between April 2010 and May 2014. Patients with chronic heart failure (HF), aged >18 years with left ventricular ejection fraction ?40% were randomized (1:1) to receive either sacubitril/valsartan 200 mg twice-daily or enalapril 10 mg twice-daily. The primary endpoint was to compare efficacy of sacubitril/valsartan to enalapril in delaying time-to-first occurrence of the composite endpoint (cardiovascular [CV] death or HF hospitalization).<h4>Results</h4>The trial was stopped after a median follow-up of 27 months, because the boundary for benefit with sacubitril/valsartan had crossed. Among 637 Indian patients in PARADIGM-HF (sacubitril/valsartan, n = 322 and enalapril, n = 315), the primary outcome, CV death, and the first hospitalization for HF occurred in 21.81% and 24.76% (HR 0.89; 95% CI, 0.646-1.231), 17.45% and 20.63% (HR 0.87; 95% CI, 0.605-1.236), and 7.48% and 9.52% (HR 0.78; 95% CI, 0.461-1.350) patients in the sacubitril/valsartan and enalapril group, respectively. The all-cause mortality (19.0% vs. 21.9%) and adverse events (78.4% vs. 82.2%) were comparatively lower in the sacubitril/valsartan than enalapril group. No significant difference was seen between the benefits of treatment in Indian and the total PARADIGM-HF cohort (p value for interaction >0.05).<h4>Conclusion</h4>Results support the use of sacubitril/valsartan in Indian patients with chronic HF with reduced ejection fraction with treatment benefits similar to global PARADIGM-HF cohort.

Project description:BACKGROUND:Sacubitril/valsartan in heart failure (HF) with reduced ejection fraction (HFrEF) was shown to be superior to enalapril in reducing the risk of death and hospitalization for HF. Our aim was to evaluate the cardiopulmonary effects of sacubitril/valsartan in patients with HFrEF. METHODS:We conducted an observational study. Ninety-nine ambulatory patients with HFrEF underwent serial cardiopulmonary exercise tests (CPET) after initiation of sacubitril/valsartan in addition to recommended therapy. RESULTS:At baseline, 37% of patients had New York Heart Association (NYHA) class III. After a median follow-up of 6.2 months (range 3?14.9 months) systolic blood pressure decreased from 117 ± 14 to 101 ± 12 mmHg (p < 0.0001), left ventricular ejection fraction (LVEF) increased from 27 ± 6 to 29.7 ± 7% (p < 0.0001), peak oxygen consumption (VO?) improved from 14.6 ± 3.3 (% of predicted = 53.8 ± 14.1) to 17.2 ± 4.7 mL/kg/min (% of predicted = 64.7 ± 17.8) (p < 0.0001), minute ventilation/carbon dioxide production relationship (VE/VCO? Slope) decreased from 34.1 ± 6.3 to 31.7 ± 6.1 (p = 0.006), VO? at anaerobic threshold increased from 11.3 ± 2.6 to 12.6 ± 3.5 mL/kg/min (p = 0.007), oxygen pulse increased from 11.5 ± 3.0 to 13.4 ± 4.3 mL/kg/min (p < 0.0001), and ?VO?/?Work increased from 9.2 ± 1.5 to 10.1 ± 1.8 mL/min/watt (p = 0.0002). CONCLUSION:Sacubitril/valsartan improved exercise tolerance, LVEF, peak VO?, and ventilatory efficiency at 6.2 months follow-up. Further studies are necessary to better clarify underlying mechanisms of this functional improvement.

Project description:PURPOSE:PARADIGM-HF demonstrated the superiority of sacubitril/valsartan over enalapril in patients with heart failure and reduced ejection fraction (HF-REF). How widely applicable sacubitril/valsartan treatment is in unselected patients with HF-REF is not known. We examined eligibility of patients with HF-REF for treatment with sacubitril/valsartan, according to the criteria used in PARADIGM-HF, in the Swedish Heart Failure Registry (SwedeHF). METHODS:Patients were considered potentially eligible if they were not hospitalized, had symptoms (NYHA class II-IV) and a reduced LVEF (≤ 40%), and were prescribed an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) at a dose equivalent to enalapril ≥ 10 mg daily. In these patients, we evaluated further eligibility according to the main additional PARADIGM-HF inclusion criteria. RESULTS:Of 12,866 outpatients in NYHA functional class II-IV with an LVEF ≤ 40%, 9577 were prescribed at least 10 mg of enalapril (or equivalent) daily. Complete additional data were available for 3099 of these patients (32.4%) and of them 75.5% were potentially eligible for treatment with sacubitril/valsartan. The most common reason for ineligibility was a low natriuretic peptide level (n = 462, 14.9%). Only a small proportion of patients were ineligible due to low eGFR or serum potassium level. Because only 78% of patients were taking ≥ 10 mg enalapril or equivalent daily, only 58.9% of all patients (75.5% of 78%) were eligible for sacubitril/valsartan. CONCLUSIONS:Between 34 and 76% of symptomatic patients with HF-REF in a 'real world' population are eligible for treatment with sacubitril/valsartan, depending on background ACEI/ARB dose. The most common reason for ineligibility is a low natriuretic peptide level.

Project description:AIMS:Limited data are available regarding the ability of sacubitril/valsartan to provide clinically meaningful health-related quality of life (HRQoL) improvements among individuals with heart failure (HF). Objective measurement of physical activity and sleep using actigraphy can provide insight into daily functioning and HRQoL. METHODS AND RESULTS:We designed an 18 week, multicenter, randomized, double-blind, double-dummy, parallel-group study to objectively assess changes in function and HRQoL directly after initiating sacubitril/valsartan vs. enalapril in participants with HF in their home environments. A total of 136 outpatient, ambulatory participants with New York Heart Association Class II or III HF with reduced ejection fraction (HFrEF) will be included in the study. Patients will undergo a 2 week baseline observational phase (continuing current HF treatment); data from the second week of this phase will be the baseline value for comparison with those of subsequent periods. Patients will then enter an 8 week blinded-treatment phase (randomly assigned 1:1 to sacubitril/valsartan or enalapril), followed by an 8 week open-label extension phase (treatment with only sacubitril/valsartan). The primary efficacy endpoint is the change in mean activity counts during the most active 30 min of the participant's day between baseline and the final randomized treatment phase measurement. Secondary endpoints include the change in mean sleep activity during the randomized and open-label phases; questionnaires will also assess HRQoL measures. Rather than analysing pooled actigraphy data, the researchers are considering each participant to be acting as his or her own control. CONCLUSIONS:This will be the first study to assess the effects of sacubitril/valsartan on objective measures of sleep and activity in individuals with HFrEF within the context of their daily lives. Wearable accelerometer devices will be used to gain insight into how the medication affects physical activity and sleep.

Project description:Sacubitril/valsartan significantly reduced heart failure hospitalization and mortality in PARADIGM-HF (Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With an Angiotensin-Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure). However, real-world data from its use are lacking.We retrospectively assessed all baseline and follow-up data of consecutive heart failure patients with reduced ejection fraction receiving therapy with sacubitril/valsartan for Class I recommendation between December 2016 and July 2017. Baseline characteristics and dose titration of sacubitril/valsartan were compared between patients in clinical practice and in PARADIGM-HF. A total of 120 patients (81% male) were switched from angiotensin-converting enzyme inhibitor or angiotensin receptor blocker to sacubitril/valsartan. A total of 20.1% of patients received dose uptitration. Patients were treated with an equipotential dose of renin-angiotensin system blockers before and after uptitration of sacubitril/valsartan (57 ± 29% vs. 53 ± 29% of target dose indicated by European Society of Cardiology guidelines; P = 0.286). However, they received a lower dose of sacubitril/valsartan in comparison with those in the PARADIGM-HF (219 ± 12 vs. 375 ± 75 mg; P < 0.001). In comparison with the patients receiving sacubitril/valsartan in PARADIGM-HF, patients in clinical practice were older and had a higher serum creatinine, higher New York Heart Association functional classification, and lower left ventricular ejection fraction (all P-value <0.05). Even in comparison with patients who experienced dropout during the run-in phase of PARADIGM-HF, real-world patients exhibited baseline characteristics indicative of more disease severity. Patients were at high absolute baseline risk for adverse outcome as illustrated by the EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure) risk score of 6 (inter-quartile range 3), in comparison with 5 (inter-quartile range 4) in PARADIGM-HF. After initiation of sacubitril/valsartan, New York Heart Association class significantly improved (P < 0.001), but systolic blood pressure dropped more than was reported in PARADIGM-HF (7.1 ± 8.0 vs. 3.2 ± 0.4 mmHg; P < 0.001).Patients in clinical practice exhibit baseline characteristics associated with more severe disease, which might lead to prescription of lower doses. Nevertheless, patients in clinical practice are at high risk of adverse outcome as illustrated by the EMPHASIS-HF risk score, underscoring the large potential for sacubitril/valsartan therapy to reduce the risk of heart failure hospitalization and all-cause mortality.

Project description:This review aims to elucidate the optimal dosing of angiotensin receptor-neprilysin inhibitor (ARNI) therapy in the heart failure (HF) treatment paradigm through examination of the trial population characteristics and the mortality benefit observed in the Prospective Comparison of ARNI with angiotensin-converting enzyme inhibitor (ACEI) to Determine Impact on Global Mortality and Morbidity in Heart Failure (PARADIGM-HF; NCT01035255) trial. Considerations regarding the initiation and titration of sacubitril/valsartan, a first-in-class ARNI, will also be addressed. The approval of sacubitril/valsartan heralded the first novel pharmacological class in over a decade for the treatment of heart failure with reduced ejection fraction (HFrEF). The PARADIGM-HF trial showed that treatment with valsartan/valsartan reduced the risk of first occurrence of either cardiovascular death or HF-related hospitalization (composite primary endpoint) by 20% compared with enalapril in patients with HFrEF. The incremental benefits of treatment with valsartan/valsartan over enalapril demonstrated in the PARADIGM-HF trial led to strong recommendations for its use over ACEIs or angiotensin receptor blockers to further reduce morbidity and mortality in the 2016 and 2017 American College of Cardiology/American Heart Association/Heart Failure Society of America updates to the guidelines for the management of HF. Although the optimal timing for the initiation of valsartan/valsartan has yet to be determined, its early use is likely to have a positive impact on patient outcomes.
