Efficacy and Safety of a Single-Pill Triple Combination of Valsartan, Amlodipine, and Chlorthalidone in Patients With Essential Hypertension Inadequately Controlled on Dual Therapy With Valsartan and Amlodipine: A Randomized, Double-Blind, Multicenter, Phase 3 Trial.

Many hypertensive patients require three or more antihypertensive agents to achieve target blood pressure. This randomized, double-blind, multicenter phase 3 trial conducted in South Korea evaluated the efficacy and safety of a single-pill triple combination therapy with valsartan (Val), amlodipine (Aml), and chlorthalidone (CTD) in patients whose blood pressure remained inadequately controlled on Val/Aml dual therapy. Patients uncontrolled after 4 weeks of Val/Aml 80/5 mg were randomized 1:1 to either Val/Aml/CTD 80/5/12.5 mg or Val/Aml 80/5 mg using a double-dummy design. After 2 weeks, doses were escalated to Val/Aml/CTD 160/5/25 mg or Val/Aml 160/5 mg, respectively, for a total treatment duration of 6 weeks. The primary endpoint was the change in mean sitting systolic blood pressure (MSSBP) from baseline to week 8. Of 193 randomized patients, 178 completed the study. The least squares mean ± SE change in MSSBP was -19.70 ± 1.31 mmHg in the Val/Aml/CTD group versus -8.71 ± 1.26 mmHg in the control group, yielding a statistically significant between-group difference of -10.99 ± 1.81 mmHg (95% CI, -14.56 to -7.41; p < 0.0001). No serious adverse events occurred in the Val/Aml/CTD group, compared with an incidence of 1.98% in the control group (p = 0.4985). Triple combination therapy with Val/Aml/CTD demonstrated superior blood pressure reduction and a favorable safety profile in patients with essential hypertension inadequately controlled on Val/Aml dual therapy, supporting its use as an effective treatment option in this population. Trial Registration: This trial was prospectively registered at ClinicalTrials.gov (identifier: NCT06416865).

Effects of Sacubitril Valsartan Combined With Vericiguat on NT-proBNP and CK-MB Levels in Patients With Chronic Heart Failure.

This study aims to probe the influence of sacubitril valsartan sodium tablets combined with vericiguat on N-terminal pro-B-type natriuretic peptide (NT-proBNP) and creatine kinase isoenzyme (CK-MB) levels in patients with chronic heart failure (CHF). One hundred and twenty CHF patients were enrolled and stratified into a control group (sacubitril valsartan sodium tablets) and a combination group (sacubitril valsartan sodium tablets + vericiguat). Outcome measures included New York Heart Association (NYHA) functional class shifts, echocardiographic indices, cardiac injury markers, 6-min walk distance (6MWD), endothelial function parameters, inflammatory mediator levels, and adverse clinical events. Following a 6-month treatment period, patients in the combination group exhibited superior functional improvement, as reflected by greater advancement in NYHA class. Echocardiographic evaluation revealed more favorable ventricular remodeling in this group, with reduced left ventricular end-diastolic and end-systolic diameters and an elevated ejection fraction. The combination group had a higher 6MWD. Biomarker analysis showed lower NT-proBNP and CK-MB levels in the combination group. Furthermore, improvements in endothelial function were noted, with decreased endothelin and elevated NO, NOS, and CGRP levels in the combination group. Markers of systemic inflammation, including CRP and IL-6, were also attenuated in the combination group. The incidence of adverse reactions and cardiovascular events did not differ significantly between the groups. Co-administration of sacubitril/valsartan and vericiguat enhances cardiac performance, optimizes vascular endothelial responsiveness, modulates heart failure-related biomarkers, and mitigates inflammatory activity in patients with CHF without increasing the risk of adverse events.

Effects of Sacubitril/Valsartan on All-Cause Hospitalizations in Heart Failure: Post Hoc Analysis of the PARADIGM-HF and PARAGON-HF Randomized Clinical Trials.

IMPORTANCE: Sacubitril/valsartan is indicated to reduce the risk of cardiovascular death and heart failure (HF) hospitalizations in patients with chronic HF. However, many of these patients are older and have multiple comorbidities that increase the risk of hospitalization for causes other than HF. OBJECTIVE: To assess the effects of sacubitril/valsartan on hospitalizations of any cause across the spectrum of left ventricular ejection fraction (LVEF). DESIGN, SETTING, AND PARTICIPANTS: This post hoc, participant-level, pooled analysis of the PARADIGM-HF (in patients with an LVEF ≤40%) and PARAGON-HF (in patients with an LVEF ≥45%) randomized clinical trials was conducted from February 5, 2024, to April 5, 2024. Participants with chronic HF, New York Heart Association classes II through IV symptoms, and elevated natriuretic peptides were randomized to treatment with either sacubitril/valsartan or a renin-angiotensin system inhibitor (RASi)-enalapril in the PARADIGM-HF trial or valsartan in the PARAGON-HF trial. INTERVENTION: Sacubitril/valsartan vs RASi (enalapril or valsartan). MAIN OUTCOMES AND MEASURES: The effects of sacubitril/valsartan on time to first investigator-reported all-cause and cause-specific hospitalizations were examined using Cox proportional hazards models, stratified by geographic region and trial. Effect modification by LVEF as a continuous function was examined. RESULTS: Among 13 194 participants in the PARADIGM-HF and PARAGON-HF trials, mean (SD) patient age was 67 (11) years, 8883 patients (67.3%) were male, and mean (SD) LVEF was 40% (15%). Sacubitril/valsartan significantly reduced the risk of all-cause hospitalization (ACH) compared with RASi over a median (IQR) follow-up period of 2.5 (1.8-3.1) years (hazard ratio [HR], 0.92; 95% CI, 0.88-0.97; P = .002). The incidence rate of first ACH was 25 (95% CI, 24-26) per 100 patient-years in the sacubitril/valsartan arm and 27 (95% CI, 26-28) per 100 patient-years in the RASi arm. The absolute risk reduction (ARR) was 2.1 per 100 patient-years, corresponding to a number needed to treat (NNT) of 48 patient-years of treatment exposure to prevent 1 ACH. Reductions in overall hospitalizations seemed primarily driven by lower rates of cardiac and pulmonary hospitalizations with sacubitril/valsartan. Patients in the 2 treatment arms had similar rates of composite noncardiac hospitalizations. Treatment heterogeneity on ACH by LVEF was observed (P for interaction = .03), with benefits most apparent in patients with an LVEF less than 60% (HR, 0.91; 95% CI, 0.86-0.96), but not in patients with an LVEF of 60% or more (HR, 0.97; 95% CI, 0.86-1.09). CONCLUSIONS AND RELEVANCE: In this post hoc pooled analysis of 13 194 patients with chronic HF in the PARADIGM-HF and PARAGON-HF randomized clinical trials, sacubitril/valsartan significantly reduced hospitalization for any reason, with benefits most apparent in patients with an LVEF below normal. This reduction appeared to be principally driven by lower rates of cardiac and pulmonary hospitalizations. TRIAL REGISTRATIONS: ClinicalTrials.gov Identifiers: NCT01035255 (PARADIGM-HF) and NCT01920711 (PARAGON-HF).

Impact of estimated total blood volume on NT-proBNP response to angiotensin receptor-neprilysin inhibition in acute heart failure: Insights from the PREMIER study.

BACKGROUND: Sacubitril/valsartan (Sac/Val) reduces N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in acute heart failure (AHF), particularly in patients with reduced ejection fraction. However, whether estimated total blood volume (TBV), calculated using anthropometric equations, is associated with heterogeneity in biomarker response remains uncertain. METHODS: This post hoc exploratory sub-analysis of the PREMIER randomized trial evaluated whether baseline estimated TBV was associated with heterogeneity in NT-proBNP reduction after Sac/Val compared with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) therapy. Estimated TBV was calculated using validated anthropometric equations and dichotomized at the median (4.05 L). Patients were further stratified by left ventricular ejection fraction (LVEF <40% vs ≥40%). The primary endpoint was the proportional change in NT-proBNP from baseline to Week 8. RESULTS: Among 376 patients, 372 with baseline estimated TBV data were analyzed. In the high TBV group, Sac/Val was associated with greater NT-proBNP reduction than ACEI/ARB (-56% vs -32%; ratio of change, 0.67; 95% confidence interval, 0.53-0.84; P = .001), whereas no significant difference was observed in the low TBV group (P for heterogeneity = 0.063). In patients with LVEF <40%, Sac/Val was associated with greater NT-proBNP reduction in both TBV groups. In patients with LVEF ≥40%, Sac/Val was associated with greater NT-proBNP reduction in the high TBV group, whereas the point estimate in the low TBV group numerically favored ACEI/ARB. CONCLUSIONS: In this exploratory post hoc analysis, higher estimated TBV was associated with greater NT-proBNP reduction after Sac/Val, particularly among patients with LVEF ≥40%. These findings are hypothesis-generating and require external validation. TRIAL REGISTRATION: ClinicalTrials.gov, NCT05164653; Japan Registry of Clinical Trials, jRCTs021210046.

Efficacy and Safety Profile of a Triple Single-Pill Combination of Valsartan/Amlodipine/Chlorthalidone in Patients with Uncontrolled Hypertension.

PURPOSE: This randomized, double-blind, multicenter Phase III study evaluated the efficacy and safety profile of a single-pill triple combination of valsartan/amlodipine/chlorthalidone (KDF1901, Valdipine Plus) compared with a dual combination of valsartan/amlodipine (KDF1901-R) in patients with essential hypertension. METHODS: Patients (n = 294) with inadequately controlled hypertension after a 4-week run-in phase with valsartan/amlodipine (80/5 mg) were randomized to receive KDF1901 (valsartan/amlodipine/chlorthalidone 160/10/25 mg, n = 147) or KDF1901-R (valsartan/amlodipine 160/10 mg, n = 147) for 8 weeks. The primary efficacy endpoint was the change in mean sitting systolic blood pressure (MSSBP) from baseline to week 8. Secondary endpoints included changes in mean sitting diastolic blood pressure (MSDBP), BP normalization rates, and response rates. Safety profile outcomes assessed treatment-emergent adverse events (TEAEs), laboratory parameters, and serious adverse events. FINDINGS: At week 8, the KDF1901 group exhibited a significantly greater reduction in MSSBP (-22.8 ± 1.0 mmHg) compared with the dual therapy group (-16.7 ± 1.0 mmHg, P < 0.0001). Similarly, the mean MSDBP reduction was significantly greater with KDF1901 (P = 0.0006). BP normalization rates (75.9% vs 54.5%, P < .0001) and response rates (73.8% vs 51.7%, P < 0.0001) were significantly higher in the triple combination group. Overall, the incidence of TEAEs was similar between groups (24.7% vs 21.5%, P = 0.5783), with mild cases of dizziness were most commonly reported. Exploratory ad hoc analyses showed statistically greater changes in sodium, potassium, and uric acid levels with triple therapy, but clinically meaningful extreme electrolyte abnormalities were rare in both groups, and the overall laboratory profile remained acceptable. IMPLICATIONS: This trial reported that the single-pill triple combination KDF1901 significantly improved BP control compared with dual therapy without compromising tolerability. GOV IDENTIFIER: NCT07116863.

Angiotensin-Neprilysin Inhibition and Left Ventricular Assist Device Therapy: Primary Results of the ENVAD-HF Trial.

BACKGROUND: The role of heart failure-specific therapies in left ventricular assist device (LVAD) recipients is unclear, and observational data suggest improved outcomes with neurohormonal blockers. OBJECTIVES: ENVAD-HF (Multicenter, Randomized, Open-Label, Parallel Group, Study to Evaluate the Use of Sacubitril/Valsartan in HeartMate 3 LVAD Recipients) sought to evaluate the safety and tolerability of the angiotensin-neprilysin inhibitor sacubitril/valsartan vs standard of care (SOC) for managing blood pressure (BP) in HeartMate 3 LVAD recipients. METHODS: ENVAD-HF was a prospective multicenter, randomized, open-label study of sacubitril/valsartan vs SOC for managing BP (mean arterial pressure goal: 75-90 mm Hg) in stable LVAD recipients with 12-month follow-up. The composite primary endpoint was time to death, deterioration in renal function, hyperkalemia, or symptomatic hypotension leading to drug withdrawal. Exploratory endpoints included clinical and biomarker assessments and patient-reported outcomes. RESULTS: In 60 randomized patients (30 in each arm), sacubitril/valsartan compared with SOC demonstrated an HR of 0.42 (95% CI: 0.08-2.18; P = 0.30) for the primary endpoint at 12 months. Two primary endpoints were reached in the sacubitril/valsartan group (1 death and 1 symptomatic hypotension event) compared with 5 in the SOC group (2 deaths, 2 worsening renal function events, and 1 symptomatic hypotension event). Numerical trends in favor of sacubitril/valsartan were noted for other exploratory endpoints, including a reduced number of BP medications (difference: -1.09 [95% CI: -1.52 to -0.66]; P < 0.0001) and a significantly better Kansas City Cardiomyopathy Questionnaire-Overall Summary Score (improvement: +10.6 [95% CI: 2.6-18.7]; P = 0.011). CONCLUSIONS: ENVAD-HF, a prospective randomized controlled trial of angiotensin-neprilysin inhibition in stable HeartMate 3 LVAD recipients, demonstrated the safety and tolerability of this therapy in this unique population. The trial forms the basis for a pivotal trial to investigate the usefulness of HF-specific therapies in the LVAD population. (Sacubitril/Valsartan in Left Ventricular Assist Device Recipients [ENVAD-HF], NCT04103554; A multicENter, randomized, open-label, parallel group, pilot study to evaluate the use of sacubitril/valsartan in HeartMate 3 LVAD recipients, 2019-003888-22).
