About this study

  1. (RENEWAL-EXERCISE trial) The investigators hypothesize that the increased sympathetic nervous system activation that is associated with resistant hypertension is a major contributor in the pathogenesis of exercise diastolic dysfunction and that modulation of the sympathetic nervous system activity with radiofrequency ablation of the renal artery sympathetic nerve fibers delivered via a treatment catheter, will have a significant effect on the diastolic function that is beyond BP-lowering effect.
  2. (RENEWAL-REGRESSION trial) The major cause of mortality and morbidity in hypertension is atherosclerotic cardiovascular disease. the significant decrease in the sympathetic nervous system activation after renal sympathetic denervation will contribute to regression over and beyond it's effect of blood pressure reduction.
  3. (RENEWAL-PREDICT trial) No data exists regarding the tests or methods predicting the successful renal denervation causing the effective reduction of BP. For these, the investigators sought to perform the new tests such as adenosine infusion test during procedure and skin sympathetic activity measurement before and immediate post-procedure (detailed explanation provided in section of Methods) and then evaluate the association between these tests and reduction of BP following procedures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in coronary atheroma

    Evaluation of the change in coronary atheroma (change in percent atheroma volume (PAV) and the change in nominal atheroma volume in the 10-mm subsegment with the greatest disease severity at baseline), analyzed by an IVUS, between baseline and 2-year IVUS in the patients with CAD) for RENEWAL-REGRESS trial

    Measured: change in coronary atheroma for 24 months after renal denervation

Secondary outcomes (1)
  1. Reduction of peak exercise E/E prime

    Reduction of peak exercise E/E prime at 6 month follow up for RENEWAL-EXERCISE trial

    Measured: Peak exercise E/E prime from 6 and 12 months after renal denervation

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Renal denervation and adenosine infusion treatment in people with Resistant Hypertension, run by Yonsei University at 1 site in South Korea.

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 10 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: stopped early, as of the sponsor's last update on 28 Mar 2019. 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 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 was stopped early (reason given: The study terminated early due to the difficulty of recruiting candidates.). Results are not available in the source record.

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 in coronary atheroma (time frame: change in coronary atheroma for 24 months after renal denervation). 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 NCT01918111, 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 28 Mar 2019.
