Trial summary

Heart failure is a common condition with debilitating symptoms and a poor prognosis. Patients with heart failure have a massively overactive sympathetic nervous system which attempts to compensate for their poorly functioning heart. This ultimately has only detrimental effects.

About this study

Official title: Renal Artery Denervation in Chronic Heart Failure- Pilot

Heart failure is a common condition with debilitating symptoms and a poor prognosis. Patients with heart failure have a massively overactive sympathetic nervous system which attempts to compensate for their poorly functioning heart. This ultimately has only detrimental effects.

One of the principle mediators for this sympathetic response is found in the nerve cells in the kidneys. Whilst a significant proportion of medications used to treat heart failure act on these harmful pathways, none target the kidney sympathetic-nerve cells specifically. Additionally, because of their multiple sites of action these drugs all have side effects.

A new procedure that has recently been developed for the treatment of high blood pressure is renal denervation. This involves inserting a small catheter through the femoral artery and passing it to the kidney artery under x-ray guidance. From there, using radiofrequency waves, the sympathetic nerves within the kidney can be destroyed.

The investigators anticipate that this procedure will have a significant positive effect on patients with heart failure and aim to perform a pilot safety study on 7 individuals with advanced heart failure to assess its safety and effectiveness. The investigators hypothesise that renal artery denervation will lead to significant clinical and biochemical improvements in patients with marked heart failure.

Read the detailed description

One of the key physiological changes seen in heart failure patients is overactivity of the sympathetic nervous system. This is a homeostatic response produced by the body in an attempt to compensate for a poorly functioning heart and the resultant underperfused tissues. In acute heart failure this has a positive effect but in chronic heart failure, the long standing sympathetic overactivity causes multiple undesirable side effects including profound vasoconstriction, increased sodium reabsorption by the kidneys, renin release and decreased renal blood flow. Afferent and efferent sympathetic chains in the renal artery play an important role in the mediation of this response.

Current management of heart failure principally hinges on drugs that attempt to attenuate or interrupt this response via renin angiotensin system, adrenoreceptors or the renal tubules. These drugs have multiple side effects, partly because of their multiple sites of action. None directly target the sympathetic discharge at its source.

The development of renal artery denervation opens a unique opportunity for potentially longlasting relief of this intense renal sympathetic over-activity. The technique has a current role in the management of resistant hypertension where it has shown very favourable results with minimal side effects. The investigators envisage that this technique could also be highly beneficial to patients with heart failure by directly interrupting this sympathetic overactivity. This initial study involving 7 patients is a pilot safety study to assess this potential.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Renal Artery Denervation in people with Congestive Cardiac Failure, run by Imperial College London at 2 sites in United Kingdom.

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 3 inclusion and 6 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 23 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Number of Participants with Adverse Events (time frame: 1 year). 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 NCT01584700, which also lists 2 linked publications.

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 23 Aug 2016.
