Personalised Prospective Comparison of ARni With ArB in Patients With Natriuretic Peptide eLEvation (PARABLE)

A Randomised, Controlled, Double-blind, Double-dummy, Clinical Trial Comparing Sacubitril-Valsartan Versus Valsartan in Asymptomatic, Stage A/B HFpEF Patients With Elevated Natriuretic Peptide and Abnormal LAVI. (Previously NCT02682719)

Sacubitril-valsartan, an Angiotensin Receptor Blocker-Neprilysin Inhibitor (ARNI), currently marketed for the management of heart failure, has been shown to reduce cardiovascular morbidity and mortality in stage C heart failure with reduced ejection fraction. In stage C HFpEF, sacubitril-valsartan has also been shown to reduce left atrial volume index measured using echocardiography over a 9 month timeframe. The PARABLE study investigates the hypothesis that sacubitril-valsartan can provide benefits in terms of left atrial structure and function as well as left ventricular structure and function in asymptomatic (stage A/B HFpEF) patients. This is a prospective, randomised, double-blind, double-dummy, phase II study design. The patient population will have hypertension and/or diabetes together with preserved ejection fraction, elevated natriuretic peptide (NP) and abnormal left atrial volume index (LAVI, > 28 mL/m2).

Detailed Description

Background.

An effective prevention strategy is critical if the established epidemic of heart failure and cardiovascular disease is to be curbed. This is particularly important in the context of increasing community prevalence of stage B HFpEF and left ventricular diastolic abnormalities associated with hypertension and diabetes and requires community diagnostics and targeted preventative therapies. Individualising risk beyond the presence of established risk factors can be achieved with NP assessment. Elevated NP in a population with established cardiovascular disease defines a group more prone to cardiac dysfunction, heart failure and other cardiovascular events. This can be used to risk stratify asymptomatic populations, targeting those most likely to need intensive intervention and follow-up.

In the prospective, randomised, pragmatic St Vincent's Screening TO Prevent Heart Failure (STOP-HF) trial [Ledwidge 2013], NP-based screening and collaborative care with general practice provided a multi-faceted intervention for patients with risk factors for heart failure. This involved community NP screening, improved use of RAAS modifying therapy, collaborative care with general practice as well as cardiovascular coaching for patients with mild elevations of BNP (>50 pg/mL).The intervention reduced stage B and C heart failure, most of which was preserved ejection fraction, as well as major adverse cardiovascular events requiring hospitalisation. This first of type study, along with a second study in diabetes [Huelsmann 2013], indicates that a biomarker driven strategy based on NP screening amongst stage AB heart failure patients is feasible and has an impact on heart failure and other cardiovascular diseases. These studies have been incorporated into 2017 American Heart Association/American College of Cardiology guidelines as well as other international guideline recommendations in heart failure.

However, while successful, the STOP-HF biomarker strategy lacks a specific pharmacological intervention linked to the screening biomarker, NP. An analysis of the STOP-HF follow-up study, supports other work showing that the minor C allele of genetic variant rs198389 of the NPPB gene (in the promoter region) is associated with sustained, elevated circulating levels of BNP and reduced incidence of left ventricular dysfunction over a five-year follow up period. These data support the hypothesis that use of LCZ696 to pharmacologically raise NP could provide cardioprotection in stage A/B heart failure patients. As neprilysin degrades biologically active NP, LCZ696 increases myocardial cyclic guanosine monophosphate (cGMP) which reduces vascular and myocardial stiffness as well as hypertrophy. This could improve cardiac structure and performance. NPs also stimulate natriuresis, diuresis, vasodilation and have been shown to have anti-fibrotic and anti-sympathetic benefits, which could augment the STOP-HF preventative strategy with a specific pharmacological intervention. [Ledwidge 2103, Phelan 2012, Potter 2006, Gardiner 2007]. Atrial tissue gene expression of BNP in patients with stage B HFpEF is associated with atrial fibrosis, procollagen expression and presence of M2 monocyte-derived-macrophage marker CD163 [Watson 2020]. Further analyses of the STOP-HF follow-up study shows that BNP strongly associates with the presence of atrial cardiomyopathy, an independent predictor of new onset major adverse cardiovascular events.

Taken together, these data could support a role for sacubitril-valsartan versus valsartan alone in favourably modulating vascular compliance, cardiac structure, cardiac function as well as progression of left atrial structural and functional abnormalities amongst patients with stage B HFpEF. If left atrial structure and function is also associated with new onset major adverse cardiovascular events, the intervention could also modulate cardiovascular events. Finally, new CMRI imaging measures of cardiac function, such as CMR e' have been developed and will allow full characterisation of the cardiovascular impact of the intervention, including in subsets of patients with established atrial cardiomyopathy.

Rationale for the study

Elevated NP in an at-risk population independently identifies cardiovascular risk, which can be specifically targeted by LCZ696. In a small proportion of patients (<5%) with cardiovascular risk factors and elevated NP, significant asymptomatic LV systolic dysfunction will be present and for these RAAS modifying therapy is mandated. However, there is a larger group of patients with elevated NP who have stage B HFpEF, with or without diastolic dysfunction. These patients may have preclinical, or asymptomatic, left ventricular diastolic dysfunction (ALVDD), atrial cardiomyopathy (AC) or both and are at heightened risk for heart failure and other cardiovascular events [Watson 2020].

The increase in NP in stage B HFpEF, ALVDD and AC is likely a fibro-inflammatory signal, which in-turn contributes to tissue remodelling, vascular disease, myocardial stiffening and left ventricular dysfunction. For example, hypertension, a common risk factor for ALVDD, is associated with an adverse accumulation of fibrous tissue and studies have demonstrated a strong relationship between ventricular stiffness, myocardial collagen content and plasma levels of myocardial collagen turnover markers [Hogg 2004, Querejeta 2004]. Cardiac inflammation, fibrosis and hypertrophy drive the pathophysiology [Gardiner 2007, Martos 2007] associated with vascular disease, myocardial stiffening, and left atrial as well as left ventricular dysfunction. [Phelan 2012, Jannuzzi 2019] Interrupting this pathophysiological process at an early stage before the development of ventricular dysfunction may prevent or slow development to heart failure and also have an impact on the development of other cardiovascular events driven by this pathophysiological process. This may be particularly important for prevention of the development of a sub-type of stage C HFpEF characterised by older age, elevated LAVI, atrial fibrillation and chronic kidney disease, which puts patients at very high risk adverse outcome [Shah 2015]. Importantly, there is currently no specific disease modifying therapy for these patients, beyond conventional risk factor control.

Accordingly, suppressing the RAAS will reduce the pro-fibrotic impact of angiotensin II. Addition of sacubitril, which reduces degradation of endogenous, cardio-protective NPs, could reduce pulse pressure, myocardial stiffness and augment the beneficial anti-inflammatory and anti-fibrotic effects of NPs beyond conventional RAAS modifying therapy. The latter may be mediated through impacts on the innate immune system, fibro-inflammation and monocyte-derived-macrophages in the myocardium [Watson 2020].

Several studies have shown that the interplay between the myocardium and extracellular matrix (ECM) can now be evaluated via analysis of serum samples of markers of collagen turnover. [Martos 2007, Querejeta 2007] Altered serum levels of collagen markers (e.g. Collagen 1A1) and matrix metalloproteinase (e.g. MMP-2 and MMP-9) suggest increased collagen turnover associated with fibrosis in diastolic heart failure. [Martos, 2007, Ahmed 2006, Nikishimi 2006] Other biomarkers of cardiac structure and function of relevance in ALVDD/AC include Galectin 3 and ST-2, biomarkers of cardiac remodelling and tissue fibrosis. Finally, cGMP, which blunts activation pathways and diminishes hypertrophy, fibrosis, cellular toxicity, and maladaptive remodelling in the myocardium, may also be modulated by sacubitril-valsartan, not only through inhibition of breakdown of BNP, but also ANP and other vasoactive peptides [Ibrahim 2019].

In high risk patients with preserved ejection fraction, elevated LAVI reflects increased left ventricular filling pressures, fibro-inflammation and is a strong, continuous marker of diastolic dysfunction as well as future cardiovascular events. Interventions that could improve myocardial performance and reduce progression of LAVI and other structural abnormalities might also help prevent cardiac morbidity and progression to stage B/C HFpEF. Sacubitril-valsartan has been shown to modulate NP activity and reduce LAVI in comparison with valsartan in the PARAMOUNT study [Solomon 2012]. The reduction of 2.6 mL/m2 with LCZ696 compared with an increase of 0.3 mL/m2 with valsartan (p=0.007 for difference) from a baseline of 36 mL/m2 over 36 weeks appears to be clinically significant in these patients with preserved ejection fraction. However, further work is required to understand the implications of this result in stage A/B HFpEF, especially using more precisely defined myocardial structure and function with cardiac magnetic resonance imaging (cMRI). Furthermore, in the PARAGON-HF study (Solomon 2019), there was no significant benefit of sacubitril-valsartan in patients with HFpEF with respect to the primary composite outcome of hospitalisation and death. The differential effect of sacubitril-valsartan versus valsartan in relation to left ventricular ejection fraction as well as stage B versus C HFpEF requires further evaluation. No study has evaluated sacubitril-valsartan in patients with stage A/B HFpEF, elevated natriuretic peptides and abnormal LAVI.

Aim

The main aim of the PARABLE trial is to assess the impact of sacubitril-valsartan versus valsartan alone on structural, functional and biochemical abnormalities of the myocardium in an asymptomatic cohort with preserved ejection fraction, cardiovascular risk factors, abnormal LAVI and elevated NP (brain type natriuretic peptide [BNP] and/or N-terminal of the prohormone BNP [NT-proBNP]).

PARABLE tests the hypothesis that sacubitril-valsartan versus valsartan alone would result in beneficial effects on atrial and ventricular structure and function, thereby preventing progression of cardiac abnormalities in stage B HFpEF.
