About this study

The purpose of this post market clinical investigation is to complete preliminary evaluation on whether or not concomitant renal denervation with the EnligHTN™ Renal Denervation System and cardiac ablation will result in improved outcomes as compared to ablation alone in patients with uncontrolled hypertension being treated for Atrial Fibrillation

Read the detailed description

This is a post market, prospective, multicenter, 2:1 randomized study of the EnligHTN™ Renal Denervation System in conjunction with atrial fibrillation ablation. Up to one hundred subjects with paroxysmal or persistent atrial fibrillation and uncontrolled hypertension will be enrolled in the study. All subjects will undergo cardiac ablation for the treatment of atrial fibrillation. Per the 2:1 randomization, a minimum of 50 or 2/3 of the total patient cohort will also undergo renal artery ablation. Subjects will be followed up to years (2) years post procedure.

What is being measured

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

  1. Number of Participants With Freedom From Atrial Fibrillation at 12 Month

    The freedom from atrial fibrillation was assessed based on electrocardiographic data during nine months following the blanking period including the one week recording coinciding with the 12 month follow-up visit (9 months following the 3 month blanking period).

    Measured: 12 months

Secondary outcomes (11)
  1. Major Adverse Cardiac Events (MACE)

    Major adverse cardiac events (MACE) were summarized as a percentage based on number of subjects at baseline for each group (RDN+AF group = 39, AF group = 22).

    Measured: 7 days, 6 months, 12 months, and 24 months post procedure

  2. Percentage of Participants Who Experience Peri-procedural Events

    Peri-procedural events within 30 days post procedure were summarized as a percentage based on the number of subjects at baseline for each group (RDN+AF group= 39, AF group=22)

    Measured: 30 days post procedure

  3. Assessment of Renovascular Safety as Measured by New Renal Artery Stenosis or Aneurysm at the Site of Ablation

    Renovascular safety (new renal artery stenosis or aneurysm) was summarized as a percentage based on the number of subjects at baseline for each group (RDN+AF group= 39, AF group=22).

    Measured: 6 months and 12 months post procedure

  4. Renal Function Change Based on Estimated Glomerular Filtration Rate (eGFR) (Renal Denervation Group Only) at 6 Months

    Measured: Baseline and 6 months

  5. Renal Function Change Based on eGFR (Renal Denervation Group Only) at 12 Months

    Measured: Baseline and 12 months

  6. Recurrence of Atrial Fibrillation (AF) Based on Electrocardiographic Data up to 2 Years Following the Initial Cardiac Ablation Procedure.

    Recurrence of AF was summarized as a percentage based on the number of subjects who underwent the procedure (RDN+AF group= 39, AF group=20)

    Measured: 3 months, 6 months, 12 months, 24 months

  7. Percentage of Participants Achieving Office Systolic Blood Pressure < 140 mmHg

    Measured: 6 months post procedure

  8. Change in Ambulatory Blood Pressure at 12 Months

    Change in Ambulatory Blood Pressure was summarized based on subjects with available data at both time points (RDN+AF group= 22, AF group=14)

    Measured: Baseline and 12 months post procedure

  9. Change in Ambulatory Blood Pressure at 24 Months

    Change in Ambulatory Blood Pressure was summarized based on subjects with available data at both time points (RDN+AF group= 17, AF group=12)

    Measured: Baseline and 24 months post procedure

  10. Change in Office Blood Pressure at 12 Months

    Change in Office Blood Pressure was summarized based on subjects with available data at both time points (RDN+AF group= 33, AF group=15)

    Measured: Baseline and 12 months post procedure

  11. Change in Office Blood Pressure at 24 Months

    Change in Office Blood Pressure was summarized based on subjects with available data at both time points (RDN+AF group= 29, AF group=16).

    Measured: Baseline and 24 months post procedure

Questions about this trial

What is this clinical trial studying?

A study testing Renal Artery Ablation and Cardiac Ablation in people with Persistent Atrial Fibrillation and Paroxysmal Atrial Fibrillation, run by Abbott Medical Devices at 2 sites in Germany.

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 21 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 22 May 2020. 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 Germany. 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?

Yes. Results are posted in the registry (first posted 22 May 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Freedom From Atrial Fibrillation at 12 Month (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 NCT01907828, 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 22 May 2020.
