Brief Summary
An international, multi-center, prospective, blinded, randomized, controlled trial. The objective is to demonstrate that catheter-based renal denervation is an effective and safe treatment for uncontrolled hypertension.

Study Arms (2)
Renal Denervation
EXPERIMENTALSubjects are treated with the renal denervation procedure after randomization.
Control
OTHERSubjects randomized prior to enrollment closure were treated with sham renal denervation (angiography only). Once enrollment was closed and the protocol revised, no control subjects crossed-over.
Interventions
Subjects randomized to the renal denervation group underwent angiography and renal denervation.
Prior to enrollment closure, subjects were treated with sham renal denervation. After enrollment closure, subjects previously enrolled were no longer eligible to cross-over.
Subjects who met all criteria after the screening period did undergo a renal artery angiogram to evaluate renal artery anatomy. Only subjects with eligible renal artery anatomy were randomized.
Eligibility Criteria
You may qualify if:
- Individual is on maximally tolerated stable medication regimen including 3 or more anti-hypertensive medications of different classes, one of which must be a thiazide or thiazide-like diuretic
- Individual has office SBP greater than or equal to 140mmHg and less than 160mmHg
- Individual has ABPM average SBP greater than or equal to 135 mmHg
You may not qualify if:
- Individual lacks appropriate renal artery anatomy
- Individual has eGFR of less than 30
- Individual has Type I diabetes mellitus
- Individual has had one or more episodes of orthostatic hypotension
- Individual requires chronic oxygen other than nocturnal respiratory support for sleep apnea
- Individual has primary pulmonary hypertension
- Individual has other concomitant conditions that may adversely affect the patient or the study outcomes
- Individual is pregnant, nursing or planning to be pregnant
- Individual has had a previous organ transplant
