What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a procedure called renal denervation, which uses energy to calm overactive nerves in the kidneys, to see if it can safely lower diastolic blood pressure (the bottom number) in people with isolated diastolic hypertension. About 124 adults who have never taken blood pressure medication will be randomly assigned to receive the real procedure or a sham (fake) procedure. The main goal is to check if the real procedure reduces average 24-hour diastolic blood pressure after 6 months.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 124 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Expected to finish

Jul 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria 1. Age ≥18 years, with no restriction on sex or ethnicity; 2. Diagnosis of primary hypertension, with no prior use of antihypertensive medication, and in the untreated state presenting with office systolic blood pressure (SBP) \<140 mmHg and diastolic blood pressure (DBP) ≥90 mmHg, as well as 24-hour ambulatory blood pressure monitoring (ABPM) showing SBP \<130 mmHg and DBP ≥80 mmHg; 3. Willingness to participate and provision of written informed consent. Exclusion Criteria 1. DBP ≥110 mmHg; 2. Secondary hypertension; 3. Requirement for antihypertensive or blood pressure-lowering medications due to comorbid conditions (e.g., SGLT2 inhibitors, GLP-1 receptor agonists); 4. Cardiac arrhythmias interfering with blood pressure measurement (e.g., atrial fibrillation); 5. Contraindications to RDN, including renal transplantation, renal insufficiency (eGFR \<45 mL/min/1.73 m²), renal artery anatomy unsuitable for the procedure (inability to access the renal vasculature; renal artery diameter \<4 mm or length \<20 mm; hemodynamically or anatomically significant renal artery abnormalities or stenosis; prior coronary or renal artery interventions including angioplasty or stenting), and severe hepatic impairment; 6. Contraindications to interventional procedures such as coagulopathy; 7. Pregnancy, planning pregnancy, or breastfeeding; 8. Life expectancy \<1 year; 9. Participation in another clinical trial.
