About this study

Official title: A Renal Artery Denervation Feasibility Study of the MetAvention Integrated Radio Frequency Denervation System for the Treatment of Hypertension

The objective of the study is to evaluate the safety of renal denervation using the iRF System and to understand any potential improvement in hypertension.

Read the detailed description

This study is a prospective, single-arm, multi-center, non-randomized trial to evaluate the initial safety and performance of renal denervation with the iRF system for the treatment of hypertension.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • iRF System Renal DenervationDevice

    The iRF System is a percutaneous, catheter-based device which uses RF energy to circumferentially denervate the sympathetic nerves surrounding the artery

What is being measured

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

  1. Rate of Major Adverse Events

    Incidence of the following Major Adverse Events (MAEs)

    • Death (all-cause)
    • New onset end stage renal disease
    • Significant embolic events resulting in end-organ damage
    • Renal artery perforation or dissection requiring intervention
    • Hospital admission for hypertensive crisis not related to confirmed non-adherence with medications or protocol
    • New renal stenosis > 70 %

    Measured: Index Procedure through 30 days

Secondary outcomes (3)
  1. Change in Systolic/Diastolic Blood Pressure - Average Automated Office Blood Pressure

    Change from baseline in systolic/diastolic blood pressure as indicated by average automated office blood pressure

    Measured: Time Frame: 30, 90, 180 and 365 days

  2. Change in Systolic/Diastolic Blood Pressure - Ambulatory Blood Pressure Monitoring

    Change from baseline in systolic/diastolic blood pressure as indicated by ambulatory blood pressure monitoring

    Measured: Time Frame: 90, 180 and 365 days

  3. Effects on renal function assessed with glomerular filtration rate

    Change from baseline in renal function as indicated by eGFR

    Measured: Time Frame: 30, 90, 180 and 365 days

Questions about this trial

What is this clinical trial studying?

A study testing iRF System Renal Denervation in people with Hypertension and Metabolic Syndrome, run by Metavention at 2 sites in Georgia.

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 4 inclusion and 33 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 15 Mar 2023. 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 Georgia. 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.

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?

Rate of Major Adverse Events (time frame: Index Procedure through 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 Mar 2023.
