Sham Controlled Clinical Trial of Renal Denervation in Patients With Resistant Hypertension

September 13, 2023 updated by: Baker Heart and Diabetes Institute

The Australian SHAM Controlled Clinical Trial of Renal DeNervation in Patients With Resistant Hypertension (AUSHAM-RDN-01)

The purpose of this study is to assess the efficacy of catheter-based renal denervation in reducing blood pressure in patients with resistant hypertension compared to a sham procedure. Patients will be randomized to RDN or sham control in a 2:1 ratio. All participants will be switched to a single pill triple combination treatment prior to the procedure.

A total of 105 patients will be recruited into the study, 70 patients in the RDN arm and 35 patients in the sham control arm.

The duration of this study is 36 months.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
105

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • systolic office BP ≥140mmHg and ambulatory day time average ≥135mmHg despite concurrent treatment with ≥3 anti-hypertensive drugs

Exclusion Criteria:

  • renal artery anatomy ineligible for treatment
  • eGFR <15mL/min/1.73m2 (using MDRD calculation)
  • myocardial infarction, unstable angina or cerebrovascular accident within 3 months of screening visit
  • life expectancy of <12 months

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Other: Sham control
Arterial access only. No delivery of radio frequency energy to renal arteries.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

6 months post procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
