Spyral Insight study for hard-to-treat high blood pressure
Part of Heart & circulation clinical trials.
This study tests a device (Spyral catheter) that uses radio waves to calm overactive nerves in the kidney arteries, which may help lower blood pressure. It is for people who still have high blood pressure even while taking 1 to 3 medications.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 20 and 70 years old.
- Your blood pressure in the doctor's office is at least 150 (top number) and 90 (bottom number), but not above 179 (top number).
- You take 1, 2, or 3 blood pressure medicines but still have high blood pressure when checked over 24 hours (average top number 135 or higher).
- You have not had a kidney artery procedure (renal denervation) before.
- Your kidneys work well (eGFR result of 60 or more), and you do not take medicines like Ozempic or Jardiance.
- You are not pregnant, nursing, or planning pregnancy during the study.

This trial tests a new procedure to treat high blood pressure by using a special catheter to calm overactive nerves in your kidneys. It may help you achieve better blood pressure control if medications are not enough.
This trial tests a procedure that targets nerves near the kidney (renal denervation) to help lower blood pressure in people whose hypertension is not controlled despite medication. It uses a special 3D mapping system to guide the procedure.
This trial tests whether stimulating nerves around the kidney can lower blood pressure in people whose high blood pressure stays uncontrolled despite treatment. It may help by improving how the kidneys and blood vessels regulate blood pressure.
This trial tests a procedure called renal denervation to lower blood pressure in people whose medication isn't enough. It uses a special catheter to calm nerves near the kidneys that may be overactive.
This trial tests an ultrasound device that targets nerves around the kidney to lower blood pressure. It may help people whose blood pressure is not well controlled with medication.
This study tracks patients who have uncontrolled high blood pressure and are on a steady medication plan. It checks how kidney nerve treatment (renal denervation) works in real life over time.
