Angiotensin receptor blockade and neprilysin (NEP) inhibition together offer potential benefits for the treatment of hypertension and heart failure. LCZ696 is a novel single molecule comprising molecular moieties of valsartan and NEP inhibitor prodrug AHU377 (1:1 ratio). Oral administration of LCZ696 caused dose-dependent increases in atrial natriuretic peptide immunoreactivity (due to NEP inhibition) in Sprague-Dawley rats and provided sustained, dose-dependent blood pressure reductions in hypertensive double-transgenic rats. In healthy participants, a randomized, double-blind, placebo-controlled study (n = 80) of single-dose (200-1200 mg) and multiple-dose (50-900 mg once daily for 14 days) oral administration of LCZ696 showed that peak plasma concentrations were reached rapidly for valsartan (1.6-4.9 hours), AHU377 (0.5-1.1 hours), and its active moiety, LBQ657 (1.8-3.5 hours). LCZ696 treatment was associated with increases in plasma cGMP, renin concentration and activity, and angiotensin II, providing evidence for NEP inhibition and angiotensin receptor blockade. In a randomized, open-label crossover study in healthy participants (n = 56), oral LCZ696 400 mg and valsartan 320 mg were shown to provide similar exposure to valsartan (geometric mean ratio [90% confidence interval]: AUC(0-infinity) 0.90 [0.82-0.99]). LCZ696 was safe and well tolerated. These data support further clinical development of LCZ696, a novel, orally bioavailable, dual-acting angiotensin receptor-NEP inhibitor (ARNi) for hypertension and heart failure.

Aims To assess tolerability and optimal time point for initiation of sacubitril/valsartan in patients stabilised after acute heart failure (AHF). Methods and results TRANSITION was a randomised, multicentre, open‐label study comparing two treatment initiation modalities of sacubitril/valsartan. Patients aged ≥ 18 years, hospitalised for AHF were stratified according to pre‐admission use of renin–angiotensin–aldosterone system inhibitors and randomised (n = 1002) after stabilisation to initiate sacubitril/valsartan either ≥ 12‐h pre‐discharge or between Days 1–14 post‐discharge. Starting dose (as per label) was 24/26 mg or 49/51 mg bid with up‐ or down‐titration based on tolerability. The primary endpoint was the proportion of patients attaining 97/103 mg bid target dose after 10 weeks. Median time of first dose of sacubitril/valsartan from the day of discharge was Day –1 and Day +1 in the pre‐discharge group and the post‐discharge group, respectively. Comparable proportions of patients in the pre‐ and post‐discharge initiation groups met the primary endpoint [45.4% vs. 50.7%; risk ratio (RR) 0.90; 95% confidence interval (CI) 0.79–1.02]. The proportion of patients who achieved and maintained for ≥ 2 weeks leading to Week 10, either 49/51 or 97/103 mg bid was 62.1% vs. 68.5% (RR 0.91; 95% CI 0.83–0.99); or any dose was 86.0% vs. 89.6% (RR 0.96; 95% CI 0.92–1.01). Discontinuation due to adverse events occurred in 7.3% vs. 4.9% of patients (RR 1.49; 95% CI 0.90–2.46). Conclusions Initiation of sacubitril/valsartan in a wide range of heart failure with reduced ejection fraction patients stabilised after an AHF event, either in hospital or shortly after discharge, is feasible with about half of the patients achieving target dose within 10 weeks.

Aims Sacubitril/valsartan has shown efficacy and tolerability in patients with heart failure (HF) and reduced ejection fraction (HFrEF) in the ambulatory setting (PARADIGM‐HF), and following stabilisation of acutely decompensated HF (ADHF) (PIONEER‐HF and TRANSITION). However, data are lacking for the initiation of sacubitril/valsartan in newly diagnosed (de novo) HFrEF. Here, we assess the tolerability of initiating sacubitril/valsartan following ADHF in TRANSITION subgroups of patients with a de novo vs. prior diagnosis of HFrEF. Methods and results TRANSITION randomised 1002 patients to pre‐ and post‐discharge initiation of sacubitril/valsartan (analysis set n = 991, following exclusions for mis‐randomisation). In this post‐hoc analysis, tolerability to sacubitril/valsartan [proportion of patients achieving target dose (97/103 mg b.i.d.) at 10 weeks post‐randomisation], adverse events (AEs) and serious AEs (SAEs) were compared in de novo (n = 286) and prior HFrEF (n = 705) subgroups. More de novo than prior HFrEF patients achieved target dose at Week 10 (56% vs. 45%; relative risk ratio 1.30, 95% confidence interval 1.12–1.52, P < 0.001), and fewer had SAEs and permanent treatment discontinuations. Initiation of sacubitril/valsartan did not prevent the concomitant initiation and up‐titration of guideline‐directed HF therapies. De novo patients showed faster and greater decreases in N‐terminal pro‐B‐type natriuretic peptide and high‐sensitivity troponin‐T, and lower rates of HF and all‐cause rehospitalisation vs. prior HFrEF. Conclusions After ADHF, first‐line initiation of sacubitril/valsartan in de novo HFrEF, alongside the initiation of other guideline‐directed therapies, is feasible and is associated with a better risk–benefit profile than in patients with prior HFrEF. Early intervention with sacubitril/valsartan may be considered to delay disease progression in patients with de novo HFrEF. Clinical Trial Registration: http://www.clinicaltrials.gov, NCT02661217.

AimsThe clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new‐onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT‐HF (International REgistry to assess medical Practice with lOngitudinal obseRvation for Treatment of Heart Failure) is a global, prospective, and observational study designed to characterize patient trajectories longitudinally during and following an index hospitalization for HF.MethodsData collection for the registry will be conducted at ∼300 sites located in ∼40 countries. Comprehensive data including demographics, clinical presentation, co‐morbidities, treatment patterns, quality of life, in‐hospital and post‐discharge outcomes, and health utilization and costs will be collected. Enrolment of ∼20 000 adult patients hospitalized with new‐onset (first diagnosis) HF or decompensation of chronic HF over a 3‐year period is planned with subsequent 3 years follow‐up.PerspectiveThe REPORT‐HF registry will explore the clinical characteristics, management, and outcomes of HF worldwide. This global research programme may have implications for the formulation of public health policy and the design and conduct of international clinical trials.

BackgroundWe aimed to assess the safety and tolerability of different doses of canakinumab versus placebo in patients with type 2 diabetes mellitus (T2DM).MethodsData were pooled from three studies in 1026 T2DM patients with different routes of administration, treatment regimens and follow-up duration. Canakinumab groups were categorised as low (0.03 mg/kg i.v. once; N = 20), intermediate (0.1 and 0.3 mg/kg i.v. once, 5 and 15 mg s.c. monthly; N = 247), medium (1.5 mg/kg i.v. once, 50 mg s.c. monthly and 150 mg s.c. once; N = 268), and high doses (10 mg/kg i.v. once and 150 mg s.c. monthly; N = 137) and compared with placebo (N = 354). Incidences of adverse events (AEs), serious AEs (SAEs), discontinuations due to AEs, deaths, AEs of special interest related to interleukin-1β inhibition and T2DM disease, and laboratory abnormalities related to haematology and biochemistry parameters were reported. Safety was also analysed by age (<65, ≥65) and gender.ResultsAverage exposure across all groups was ≈ 6 months (maximum ~17 months). No dose response in AEs was observed but a trend towards more patients having at least one AE across canakinumab groups relative to placebo (P = 0.0152) was observed. SAEs were few and the incidence rate for most canakinumab groups was lower than that of placebo group except for the high-dose group (0.94% versus 0.58% per month in placebo). A total of five patients discontinued treatment due to AEs across treatment groups. No death was reported in any of the three studies. A small, non-significant increase in the incidence rate of infection AEs was observed on canakinumab groups relative to placebo. Canakinumab was associated with mostly mild decreases in WBC, neutrophils and platelet counts. Additionally, mild increases in SGPT, SGOT and bilirubin were reported. Overall, despite small differences, no clinically relevant findings were observed with respect to laboratory values and vital signs.ConclusionsThis pooled analysis demonstrated that canakinumab was safe and well tolerated over a treatment period up to 1.4 years at the four pooled doses evaluated, in agreement with safety findings reported in the individual studies.

AimsThe prognosis after hospitalization for acute decompensated heart failure (ADHF) remains poor, especially <30 days post‐discharge. Evidence‐based medications with prognostic impact administered at discharge improve survival and hospital readmission, but robust studies comparing pre‐discharge with post‐discharge initiation are rare. The PARADIGM‐HF trial established sacubitril/valsartan as a new evidence‐based therapy in patients with heart failure (HF) and reduced left ventricular ejection fraction (<40%) (rEF). In common with other landmark studies, it enrolled patients who were ambulatory at the time of inclusion. In addition, there is also still limited knowledge of initiation and up‐titration of sacubitril/valsartan in ACEi/ARB‐ naïve patients and in de novo HF with rEF patients.Methods and results TRANSITION is a multicentre, open‐label study in which ~1000 adults hospitalized for ADHF with rEF are randomized to start sacubitril/valsartan in a pre‐discharge arm (initiated ≥24 h after haemodynamic stabilization) or a post‐discharge arm (initiated within Days 1–14 after discharge). The protocol allows investigators to select the appropriate starting dose and dose adjustments according to clinical circumstances. Over a 10 week treatment period, the primary and secondary objectives assess the feasibility and safety of starting sacubitril/valsartan in‐hospital, early after haemodynamic stabilization. Exploratory objectives also include assessment of HF signs and symptoms, readmissions, N‐terminal pro‐B‐type natriuretic peptide and high‐sensitivity troponin T levels, and health resource utilization parameters.Conclusions TRANSITION will provide new evidence about initiating sacubitril/valsartan following hospitalization for ADHF, occurring either as de novo ADHF or as deterioration of chronic HF, and in patients with or without prior ACEI/ARB therapy. The results of TRANSITION will thus be highly relevant to the management of patients hospitalized for ADHF with rEF.
