About this study

Official title: Multicenter, Randomized, Double-blind, Active-controlled Study to Assess the Efficacy of LCZ696 Compared to Valsartan on Reduction of Mitral Regurgitation in Patients With Left Ventricular Dysfunction and Secondary Functional Mitral Regurgitation of Stage B and C

Functional MR is caused by adverse left ventricular remodeling after myocardial injury and associated with an increased incidence of heart failure and death. Because secondary functional MR usually develops as a result of LV dysfunction, diuretics, beta blockers, angiotensin-converting-enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB), and aldosterone antagonists are given to patients with functional MR in line with the guidelines in the management of heart failure. However, functional MR appears to remain common despite use of these drugs and current medical treatment is usually insufficient for reducing MR or reversing the adverse LV remodeling. As LCZ696 is a dual-acting inhibitor of the renin-angiotensin-aldosterone system (RAAS) and neutral endopeptidase (NEP), LCZ696 has greater hemodynamic and neurohormonal effects than ARB alone. Investigators try to examine the hypothesis that LCZ696 is superior to ARB alone in improving functional MR in patients with LV dysfunction and functional MR.

Read the detailed description

Functional ischemic mitral regurgitation (MR) has been reported to occur in up to 40% of patients after myocardial infarction, and the prevalence of functional MR is likely to increase with an aging population and improved survival rates for myocardial infarction. The presence of functional MR is associated with an increased incidence of heart failure and death, and patients with significant functional MR incur about a two-fold increase in the risk of mortality and about a four-fold increase in the risk of heart failure. Functional MR is caused by adverse left ventricular remodeling after myocardial injury with enlargement of the left ventricle (LV), apical and lateral displacement of papillary muscles, leaflet tethering and reduced closing forces. The leaflets are normal in secondary functional MR and the treatment is considerably different between functional and primary MR. Surgery is the only definitive therapy for primary severe MR and primary MR can usually be cured by surgical valve repair. However, surgical indications are unclear in severe functional MR, because outcomes after surgery for functional MR remain suboptimum. Operative mortality, long-term mortality and heart failure rates are still high in patients with severe functional MR despite surgical improvements. According to the current guidelines, mitral valve surgery may be considered only for severely symptomatic patients with severe secondary functional MR who have persistent symptoms despite optimal medical therapy for heart failure.

Because secondary functional MR usually develops as a result of LV dysfunction, diuretics, beta blockers, angiotensin-converting-enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB), and aldosterone antagonists are given to patients with functional MR in line with the guidelines in the management of heart failure. However, functional MR appears to remain common despite use of these drugs and current medical treatment is usually insufficient for reducing MR or reversing the adverse LV remodeling. Persistence of functional MR due to the insufficient effectiveness of current medical treatment significantly increases morbidity and mortality, and compared with surgical or percutaneous revascularization, significantly higher mortality was observed in patients managed with medical therapy.

Quantitative assessment of MR is strongly recommended in the guidelines and the regurgitant volume and the effective regurgitant orifice area (EROA) of MR can be measured accurately and reproducibly by Doppler echocardiography. The EROA of MR has an important prognostic value in primary and secondary functional MR. Because functional MR carries an adverse prognosis with a graded relationship between MR severity and reduced survival, therapies that induce beneficial reverse remodeling of the LV and reduce MR, may improve survival. ACE inhibitors and ARBs could partially attenuate LV dilatation and remodeling after myocardial injury, but there are no published data from prospective trials regarding whether attenuation of remodeling by ACE inhibitors or ARBs reduces functional MR.

LCZ696 is a dual-acting inhibitor of the renin-angiotensin-aldosterone system (RAAS) and neutral endopeptidase (NEP). As LCZ696 offers the therapeutic advantages of concomitantly blocking both RAAS and NEP, LCZ696 was more effective in reducing the risk of death from cardiovascular causes or hospitalization for heart failure in patients with chronic heart failure than ACE inhibitor. Because NEP is involved in the metabolism of a number of vasoactive peptides such as natriuretic peptides, NEP inhibitor has vasodilating effects, facilitates sodium excretion and has profound effects on LV remodeling. Trials of hypertension and heart failure with a preserved ejection fraction also showed that LCZ696 had greater hemodynamic and neurohormonal effects than ARB alone. To date, there has been no proven pharmacological therapy to improve functional MR, and the development of medical therapy should be at the forefront of research considering the limited role of surgery in managing functional MR. Investigators hypothesize that LCZ696 is superior to ARB alone in improving functional MR in patients with LV dysfunction and functional MR via synergistic effects of NEP and RAAS inhibition on LV remodeling, and try to examine this hypothesis in a multicenter, double-blind, randomized comparison study using echocardiography.

The record says: finished, as of the sponsor's last update on 9 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of effective regurgitant orifice area (EROA) of functional mitral regurgitation from baseline to 12 months follow-up (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02687932, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jan 2018; AzTrials last refreshed its copy on 7 Nov 2026.
