NCT01644604

Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • Change in Office Systolic Blood Pressure

    Baseline to 6 months post-randomization

Secondary Outcomes (1)

  • Incidence of Major Adverse Events (MAE)

    Baseline through 1 month post-randomization

Study Arms (2)

Renal denervation

EXPERIMENTAL

Subjects are treated with the renal denervation procedure after randomization and are maintained on baseline anti-hypertensive medications.

Device: MDT-2211 Renal Denervation System

Control Group

NO INTERVENTION

Subjects are maintained on baseline anti-hypertensive medications

Interventions

A percutaneous system that delivers radiofrequency (RF) energy through the luminal surface of the renal artery.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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 has an office systolic blood pressure (SBP) of ≥ 160 mmHg based on an average of 3 blood pressure readings measured at both an initial screening visit and a confirmatory screening visit
  • Individual agrees to have all study procedures performed, and is competent and willing to provide written, informed consent to participate in this clinical study.

You may not qualify if:

  • 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.
