  Purpose
The objective of this study is to demonstrate that the MDT-2211 renal denervation system is a safe and effective treatment for uncontrolled hypertension subjects despite treatment with 3 or more anti-hypertensive medications of different classes, of which one must be a diuretic, as best available antihypertensive therapy

Condition Intervention
Uncontrolled Hypertension Device: MDT-2211 Renal Denervation System

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The Clinical Study of Renal Denervation by MDT-2211 System in Patients With Uncontrolled Hypertension

Further study details as provided by Medtronic Vascular:

Primary Outcome Measures:
  • Change in Office Systolic Blood Pressure [ Time Frame: Baseline to 6 months post-randomization ]

Secondary Outcome Measures:
  • Incidence of Major Adverse Events (MAE) [ Time Frame: Baseline through 1 month post-randomization ]

Enrollment: 41
Study Start Date: July 2012
Study Completion Date: June 2017
Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Renal denervation
Subjects are treated with the renal denervation procedure after randomization and are maintained on baseline anti-hypertensive medications.
Device: MDT-2211 Renal Denervation System
A percutaneous system that delivers radiofrequency (RF) energy through the luminal surface of the renal artery.
No Intervention: Control Group
Subjects are maintained on baseline anti-hypertensive medications

Detailed Description:
The HTN-J study is a multi-center, prospective, unblinded, randomized, controlled study of the safety and effectiveness of renal denervation in subjects with uncontrolled hypertension. Bilateral renal denervation will be performed using the MDT-2211 renal denervation system - a percutaneous system that delivers radiofrequency (RF) energy through the luminal surface of the renal artery.

Criteria

Inclusion Criteria:

  • Individual is ≥ 20 and ≤ 80 years old at time of randomization.
  • Individual is receiving a stable medication regimen including full tolerated doses of 3 or more anti-hypertensive medications of different classes, of which one must be a diuretic (with no changes for a minimum of 6 weeks prior to screening) that is expected to be maintained without changes for at least 6 months.

  • Individual agrees to have all study procedures performed, and is competent and willing to provide written, informed consent to participate in this clinical study.

Exclusion Criteria highlights:

  • Individual has an estimated glomerular filtration rate (eGFR) of < 45 mL/min/1.73 m2
  • Individual has an Ambulatory Blood Pressure Monitoring (ABPM) 24 hour average SBP < 135 mmHg
  • Individual has type 1 diabetes mellitus
  • Individual requires chronic oxygen support or mechanical ventilation (e.g., tracheostomy, CPAP, BiPAP) other than nocturnal respiratory support for sleep apnea.
  • Individual has primary pulmonary hypertension.
  • Individual is pregnant, nursing or planning to be pregnant.
