Awards & highlights


This trial will allow people who haven't been helped by other medications to keep using a therapy that uses sound waves to target the nerves around the kidney.

Who is the study for?
This trial is for individuals with high blood pressure that remains uncontrolled despite taking medication. Participants must have a documented average office blood pressure of at least 140/90 mmHg and daytime ambulatory blood pressure of at least 135/85 mmHg. They should not have had severe cardiovascular events or strokes in the past three months, be pregnant, or have certain conditions like Type I diabetes or severely impaired kidney function.Check my eligibility
What is being tested?
The RADIANCE CAP study is testing ultrasound renal denervation therapy using the Paradise System to treat uncontrolled hypertension. It's an ongoing non-randomized trial providing access to this treatment while collecting data on its safety and effectiveness.See study design
What are the potential side effects?
While specific side effects are not listed here, renal denervation procedures may cause discomfort at the site of intervention, bleeding, bruising, potential damage to the renal artery, changes in blood pressure levels, and possible impacts on kidney function.

Eligibility Criteria

Exclusion Criteria

You may be eligible for the trial if you check “No” for criteria below:
My kidney's blood vessels are not suitable for treatment.
I have high blood pressure caused by another health condition, not sleep apnea.
I have high blood pressure in the lungs.
I need oxygen or a ventilator during the day, not just for sleep apnea at night.
I have been hospitalized more than once for high blood pressure crises in the last 3 months.
I have Type I diabetes or my Type II diabetes is not under control (HbA1c ≥9.0%).
I have had episodes of severe chest pain in the last 3 months.

Other Research
Common treatments for hypertension include angiotensin receptor blockers (ARBs), ACE inhibitors, and renal denervation therapy. ARBs and ACE inhibitors work by interfering with the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and fluid balance. ARBs block the angiotensin II receptors, preventing vasoconstriction and reducing blood pressure, while ACE inhibitors prevent the formation of angiotensin II, leading to similar effects. Renal denervation therapy, such as ultrasound renal denervation, disrupts the renal nerves, which play a role in blood pressure regulation by modulating sympathetic nervous system activity. This disruption can lead to a sustained reduction in blood pressure. These treatments are crucial for hypertension patients as they help manage blood pressure levels, reducing the risk of cardiovascular events and kidney damage.
