Alcohol injection to zap high blood pressure? new trial tests One-Time fix
NCT ID NCT07083765
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 2 times
Summary
This phase 3 trial tests a procedure called renal denervation, where a small amount of alcohol is injected around the kidney nerves to calm overactive signals that raise blood pressure. 142 people with uncontrolled hypertension will either get the real procedure or a sham (fake) procedure, and stop their blood pressure pills for 13 weeks. The goal is to see if this one-time treatment can safely lower blood pressure without needing daily medication.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dehydrated alcohol injection
- What this could lead to
- If it works, this could offer a one-time procedure to control high blood pressure without needing daily pills.
- What could go wrong
- The trial is currently suspended, and it's a small, early-phase study. The procedure involves risks like kidney or blood vessel damage, and it may not lower blood pressure enough.

Inclusion Criteria: 1. Has 2 office blood pressure measurements with a mean office systolic blood pressure (SBP) of ≥150 mmHg and ≤180 mmHg, AND a mean office diastolic blood pressure (DBP) of ≥90 mmHg. 2. Documented history of uncontrolled hypertension and is currently taking 0, 1, or 2 antihypertensive medications. 3. Is willing to discontinue any current antihypertensive medications for at least 13 weeks (5-week pre-procedure and 8-week post-procedure). 4. Has a mean 24-hour ambulatory SBP of ≥140 mmHg and ≤170 mmHg with required valid readings. Exclusion Criteria: 1. Has renal artery anatomy abnormalities. 2. Has previously undergone renal denervation. 3. Has an estimated glomerular filtration rate (eGFR) of ≤45 mL/min/1.73 m2, based on the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation; or is on chronic renal replacement therapy. 4. Has documented untreated sleep apnea. 5. Has any of the following conditions: severe cardiac valve stenosis, heart failure (New York Heart Association \[NYHA\] Class III or IV), chronic atrial fibrillation (defined as at least one documented episode in the 12 months before study entry), and known primary pulmonary hypertension (\>60 mmHg pulmonary artery or right ventricular systolic pressure). 6. Is pregnant or lactating at the time of enrollment or planning to become pregnant during the trial time period (female subjects only). 7. Is being treated chronically (e.g. daily use) with NSAIDs, immunosuppressive medications, or immunosuppressive doses of steroids. Aspirin therapy and nasal pulmonary inhalants are allowed. 8. Has a history of myocardial infarction, unstable angina pectoris, or stroke/TIA within 6 months prior to the planned procedure.
