Denervation of the REnal Artery in Metabolic Syndrome

Status Completed

Clinical Trial Summary

The current prevalence of hypertension as part of the metabolic syndrome is substantial and is increasing with the rise of obesity worldwide. Chronic elevation of sympathetic nervous system (SNS) activity has been identified as a common and key factor in disease states as obesity-related hypertension (ORH). The renal sympathetic nerves are a major contributor to the complex pathophysiology of this elevated SNS activity. Percutaneous renal denervation (PRDN), the deliberate disruption of the nerves connecting the kidneys with the central nervous system, has been shown to be an effective means of modulating elevated SNS activity.

This current study is an observational feasibility study, with the aim to investigate the effect of renal denervation on changes in insulin resistance and blood pressure in patients with obesity related hypertension. The investigators will study different variables: a laboratorial set, a set of blood pressure measurements and a set of investigations in the vascular laboratory.

Hypothesis

- The investigators hypothesize that renal denervation has a beneficial effect on insulin resistance.

- The investigators hypothesize that there will be no complications related to the device or procedure.

Clinical Trial Description

Objectives: The objectives of this study are: to compare changes in insulin resistance in patients with ORH after RDN; to evaluate the safety of PRDN in this patient group; to compare changes in blood pressure, laboratory parameters, arterial stiffness and SNS-activity after PRDN.

Study design: Prospective observational feasibility-study.

Study population: Patients with a high fasting glucose (fasting serum glucose ≥5.6 mmol/L(100 mg/dL)) and with an ambulatory systolic blood pressure >130mmHg.

Major endpoints: The effect of RDN on: insulin resistance, blood pressure and major adverse events. ;

Study Design

Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
