Trial summary

Although randomized trials have demonstrated there is no benefit of renal-artery stenting in addition to medical therapy for patients with atherosclerosis renal artery stenosis, many patients indeed gained benefit in daily practices after stenting, such as reduction in blood pressure and recovery in renal functions.

About this study

Official title: Fractional Flow Reserve-guided Percutaneous Renal Artery Stenting Plus Optimal Medical Therapy Versus Optimal Medical Therapy Alone In Atherosclerosis Renal-vascular Hypertension Patients: a Multicenter Randomized Trial

Although randomized trials have demonstrated there is no benefit of renal-artery stenting in addition to medical therapy for patients with atherosclerosis renal artery stenosis, many patients indeed gained benefit in daily practices after stenting, such as reduction in blood pressure and recovery in renal functions. One important gap is that there is no universal standard to determine whether to stent in these patients. Fraction Flow Reserve (FFR) has been studied for many year in chronic coronary heart disease and FFR-guided revascularization strategy is known to be better than both angiography-guided revascularization and medication alone. Based on the primary finding of FAIR-pilot study (NCT05732077), FFR-guided renal artery stenting is practical.

The overall purpose of the FAIR trial is to compare the clinical outcomes and safety of FFR-guided stenting plus optimal medical treatment (OMT) versus OMT alone in patients with renal-vascular hypertensive patients.

With the 'all comers' design, participants met the inclusive/exclusive criteria will be enrolled, and hyperemic FFR induced by dopamine will be measured in all participants. If FFR is ≥0.80, patients will be treated with OMT alone and follow up. If FFR is <0.80, participants will be randomized to stenting in the renal artery plus OMT or OMT alone on a 1:1 ratio. The blood pressure and anti-hypertensive medications will be compared before and 3 months after the procedure based on ambulatory blood pressure monitoring, all participants will be followed up for 1 year.

What is being measured

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

  1. Change in daytime mean systolic blood pressure as measured by 24-hour Ambulatory Blood Pressure Monitoring (ABPM)

    Measured: From baseline to 3 months post-procedure

  2. Change in the composite index of antihypertensive drugs

    Change in the composite index of antihypertensive drugs. Drug Composite Index = Weight (number of classes of antihypertensive drugs) × (sum of doses)

    Measured: From baseline to 3 months post-procedure

Secondary outcomes (12)
  1. Change in systolic blood pressure as measured by 24-hour ABPM

    Measured: From baseline to 3 months post-procedure

  2. Change in diastolic blood pressure as measured by 24-hour ABPM

    Measured: From baseline to 3 months post-procedure

  3. Change in home blood pressure

    Measured: From baseline to 3 months post-procedure

  4. Change in office blood pressure

    Measured: From baseline to 3 months post-procedure

  5. Change in the composite index of antihypertensive drugs to reach target blood pressure

    Change in the composite index of antihypertensive drugs to reach target blood pressure. Drug Composite Index = Weight (number of classes of antihypertensive drugs) × (sum of doses)

    Measured: From baseline to 1 year post-procedure

  6. Change in ABPM

    Measured: From baseline to 6 months, 1 year post-procedure

  7. All-cause death

    Measured: From baseline to 1 year post-procedure

  8. Cardiac death

    Measured: From baseline to 1 year post-procedure

  9. Acute myocardial infarction incidence

    Based on universal definition of acute myocardial infarction

    Measured: From baseline to 1 year post-procedure

  10. Non-fatal stroke incidence

    Based on medical records under outcome committee's judge

    Measured: From baseline to 1 year post-procedure

  11. Rehospitalization due to heart failure incidence

    Based on medical records under outcome committee's judge

    Measured: From baseline to 1 year post-procedure

  12. Change in serum creatinine or dialysis

    Measured: From baseline to 1 year post-procedure

Questions about this trial

What is this clinical trial studying?

A study testing Dopamine, Fractional Flow Reserve, Renal and Renal artery stenting in people with Renal Artery Stenosis Atherosclerotic and Secondary Hypertension Renal Arterial, run by Peking University First Hospital at 1 site in China.

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 14 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: looking for participants now, as of the sponsor's last update on 16 Aug 2024. 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 China. 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Yuxi Li, MD (00861083572283, liyuxi@pku.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in daytime mean systolic blood pressure as measured by 24-hour Ambulatory Blood Pressure Monitoring (ABPM) (time frame: From baseline to 3 months post-procedure). The study lists 2 primary outcomes in all. 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 16 Aug 2024.
