Trial summary

Background - Aortic valve stenosis (AS) is the most common heart valve disease among adults in the Western world with a prevalence of 3 % in people older than 75 years of age. AS usually deteriorates over time leading to heart failure, with high mortality if aortic valve replacement (AVR) is not performed. Read more about this study

About this study

Background - Aortic valve stenosis (AS) is the most common heart valve disease among adults in the Western world with a prevalence of 3 % in people older than 75 years of age. AS usually deteriorates over time leading to heart failure, with high mortality if aortic valve replacement (AVR) is not performed. Thus optimal timing of AVR is crucial, but can be challenging. Increasing life expectancy in our society will augment the therapeutic and socio economic impact of AS disease on our health care system. Therefore, new techniques for monitoring asymptomatic AS patients are needed. A potential approach is monitoring of LV myocardial efficiency (mechanical work/oxygen consumption). These measures have been suggested to be involved in the progression of non-valvular heart failure and closely related to prognosis, but never applied in a larger population of patients with AS. At present there are no recognized pharmacological treatments of AS. It is known that beta-blocker treatment in non-valvular systolic heart failure reduce heart rate, improves LV myocardial efficiency and reduces mortality. However, in patients with AS, the effects of beta-blockers are unknown.

Hypotheses - Treatment with the beta-blocker metoprolol succinate in patients with asymptomatic moderate to severe AS has beneficial effects on LV myocardial oxidative metabolism, myocardial efficiency and contractile function.

Objectives - To investigate if beta-blocker treatment in patients with moderate to severe, asymptomatic AS has beneficial effects on LV myocardial efficiency, contractile function and physical performance.

Design - A randomized double blind placebo controlled intervention trial. 40 patients with asymptomatic AS will be randomized to either per oral metoprolol succinate (N = 20) or placebo (N= 20) for 22 weeks.

Primary objective - Changes in myocardial efficiency

Secondary objectives - Myocardial oxygen consumption, Myocardial perfusion at rest, LV myocardial function, LVmass, Aortic valve area and transaortic valve velocities, 6 minute walking distance, N-terminal prohormone of brain natriuretic peptide, Quality of life (estimated by Minnesota living with heart failure questionnaire), LV wall stress

Methods - Patients will undergo echocardiography (resting and exercise), [11C]acetate PET and cardiac magnetic resonance imaging.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Metoprololsuccinate in people with Aortic Stenosis, run by Aarhus University Hospital at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

LV myocardial efficiency (time frame: Changes will be evaluated after an expected average of 22 weeks of treatment). 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 NCT02076711, 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 11 Nov 2015.
