This clinical investigation will enroll 260 patients in Europe. Patients with uncontrolled primary hypertension (office BP ≥150/90 mmHg and \\<180/110 mmHg) who are willing to discontinue antihypertensive medications will be screened after providing informed consent.\n\nAll eligible patients will undergo a medication washout period of at least three weeks, and those who continue to meet the eligibility requirements will be randomized in a 2:1:1 ratio to one of three groups: renal denervation (RDN), a sham procedure (renal artery angiogram only), or an open-label group (not undergoing the renal angiogram).\n\nAll subjects randomized to either the treatment or sham procedure groups will be evaluated at hospital discharge. All subjects will be evaluated at 1 and 3 months post-procedure. Additionally, patients who undergo the RDN procedure will also be evaluated at 12, 24, and 36 months post-procedure. All subjects will remain off antihypertensive medications until the primary endpoint is assessed at the 3-month follow-up visit, after which antihypertensive medications may be reintroduced.\n\nPatients in the RDN and sham-control groups, as well as all clinical follow-up assessors, will be blinded to the treatment allocation. The primary efficacy endpoint is the change in daytime ambulatory systolic blood pressure (ASBP) from baseline at three months post-procedure. The primary safety endpoint is the periprocedural major adverse event (MAE) rate at 30 days post-procedure.\n\nSubjects enrolled in the sham and open-label control groups may cross over to RDN at three months. Those who cross over will restart the follow-up schedule post-RDN procedure.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
