About this study

Official title: Renal Denervation in Patients With Diabetic Nephropathy and Persistent Proteinuria

The DERENEDIAB study is a proof-of-concept, multi-center, prospective, open, randomized, controlled study of the effectiveness of renal denervation in addition to standardized medical treatment compared to medical treatment alone in diabetic subjects with diabetic nephropathy and resistant proteinuria. Bilateral renal denervation will be performed using the Symplicity Catheter - a percutaneous system that delivers radiofrequency (RF) energy through the luminal surface of the renal artery.

What participants receive

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

  • Percutaneous renal denervation and TMNSProcedure or surgery

    Patients are treated with the renal denervation procedure after randomization and are maintained on standardized anti-proteinuric medications

  • Standardized antiproteinuric medication regimen includes an angiotensin receptor blocker , a diuretic , 25OH vitamin D3 and a statinDrug

    Patients are maintained on Standardized antiproteinuric medication regimen includes an angiotensin receptor blocker (irbesartan 300mg), a diuretic (furosemide 40mg or indapamide LP 1.5mg according to the eGFR), 25OH vitamin D3 and a statin (atorvastatin 20mg)

What is being measured

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

  1. proteinuria/creatininuria ratio

    Measured: from baseline to 1 year

Secondary outcomes (11)
  1. Number of patients with a decrease of the PU/CrU >50% ratio

    Measured: from baseline to 1 year

  2. Evaluation of the slope of decay of the PU/CrU

    Measured: from baseline to 1 year

  3. eGFR is estimated by the MDRD formula, and is expressed in mL/min/1.73m². The direct GFR will be assessed by measuring the 51Cr-EDTA plasmatic clearance

    eGFR is estimated by the MDRD formula, and is expressed in mL/min/1.73m². The direct GFR will be assessed by measuring the 51Cr-EDTA plasmatic clearance

    Measured: from baseline to 1 year

  4. Outcome of the GFR assessed by 51Cr-EDTA clearance

    Only in the experimental arm

    Measured: from randomisation to 1 year

  5. Decrease of the blood pressure assessed on ABPM

    Measured: From randomisation to 1 year

  6. Anti-hypertensive regimen score

    Measured: from baseline to 1 year

  7. Evaluation of the renal arterial anatomy

    in the experimental group:number of principal renal artery. Should be 1/ kidney of at least 4mm diameter and 10mm long. One accessory artery is acceptable if <

    Measured: from baseline to 1 year

  8. Evaluation of safety and tolerance of renal denervation in diabetic patients with overt proteinuria

    in the experimental group:Occurrence of adverse events: acute renal failure, damage on the renal artery (dissection, perforation, thrombosis), allergy to the contrast media, worsening of any dysautonomia

    Measured: from baseline to 1 year

  9. Evaluate the outcome of biological parameters

    eGFR (MDRD formula), proteinuria/creatininuria ratio

    Measured: from baseline to 1 year

  10. Evaluate the diabetic neuropathy/dysautonomy

    in the experimental:blood pressure in orthostatism, pulse wave velocimetry, RR interval on the Holter ECG, cutaneous baroreflex

    Measured: from randomisation to 1 year

  11. Evaluate the outcome of specific kidney injury markers

    in the experimental group:urinary levels of KIM1 and NGAL before and 1 year after the denervation

    Measured: from randomisation to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Percutaneous renal denervation and TMNS and Standardized antiproteinuric medication regimen includes an angiotensin receptor blocker , a diuretic , 25OH vitamin D3 and a statin in people with Diabetic Nephropathy and Persistent Proteinuria With Type II Diabetes, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 1 Jun 2016. 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 France. 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 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?

proteinuria/creatininuria ratio (time frame: from baseline to 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 NCT01588795, 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 1 Jun 2016; AzTrials last refreshed its copy on 2 Nov 2026.
