What is the purpose of this trial?

This trial tests a treatment for individuals with hypertension (high blood pressure) who take up to two different blood pressure medications. The researchers aim to determine if TIVUS™ Renal Denervation, a medical procedure, can safely and effectively lower blood pressure. Participants will receive either the actual treatment or a placebo procedure. Those with a history of hypertension who are willing to pause their medications temporarily might be suitable candidates. As an unphased trial, this study provides an opportunity to contribute to innovative research that could lead to new treatment options for hypertension.

Will I have to stop taking my current medications?

Yes, participants will need to stop taking their anti-hypertensive medications for a 4-week period before the procedure and remain off them for 2 months after the procedure.

What prior data suggests that the TIVUS system is safe for treating high blood pressure?

Research shows that the TIVUS™ Renal Denervation System has been tested for safety with encouraging results. In earlier studies using this ultrasound-based device, patients tolerated it well. Specifically, data from the REDUCED 1 trial showed that patients did not face major safety issues over a 12-month period.

Another study, the RADIANCE-HTN TRIO trial, confirmed the safety and reliability of this treatment, with no serious side effects reported. These studies suggest that the TIVUS system is safe for treating high blood pressure, as it did not cause significant negative effects in participants. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the TIVUS™ Renal Denervation System because it offers a unique approach to treating high blood pressure. Unlike traditional treatments like medications that target hormones or blood volume, this system uses ultrasound energy to target the nerves in the renal arteries, potentially reducing blood pressure by interrupting the nerve signals contributing to hypertension. This non-invasive method could provide a new option for patients who struggle with medication side effects or insufficient results from current therapies.

What evidence suggests that the TIVUS system is effective for high blood pressure?

Research has shown that the TIVUS™ Renal Denervation System can effectively lower blood pressure in individuals with hypertension. This system uses ultrasound to target nerves in the kidneys, helping to reduce blood pressure. In this trial, participants will receive either the TIVUS™ Renal Denervation System or a sham procedure. For instance, one study found that TIVUS™ reduced both daytime and nighttime blood pressure more effectively than a sham procedure. Additionally, the system demonstrated positive results within just two months after the procedure. Overall, these findings suggest that TIVUS™ could be a promising option for managing high blood pressure. ^{1 3 4 6 7}

Are You a Good Fit for This Trial?

This trial is for adults aged 22-75 with hypertension, who are on up to two blood pressure medications and willing to stop these meds for a washout period before and after the procedure. They must have controlled BP (<140/90 mmHg), be able to follow study procedures, undergo conscious sedation, and have suitable renal anatomy.

What Are the Treatments Tested in This Trial?

Interventions

• TIVUS™ Renal Denervation System

Trial Overview The THRIVE study tests the TIVUS Renal Denervation System against a sham (fake) procedure in lowering blood pressure. Participants will stop taking their usual hypertension drugs during the trial to see if this new system can effectively reduce their blood pressure without medication.

How Is the Trial Designed?

Group I: TIVUS™ Renal Denervation System Experimental Treatment 1 Intervention

Following angiogram, subjects found anatomically eligible and randomized to the renal denervation arm will be treated with the TIVUS™ Renal Denervation System.

Group II: Sham Placebo Group 1 Intervention

For those subjects randomized to the sham control, the angiogram will serve as the sham procedure.

Published Research Related to This Trial

The DENEX™ renal sympathetic denervation system demonstrated a favorable safety profile in a pilot study involving 16 patients with resistant hypertension, with no major adverse events reported during the 6-month follow-up.

Patients experienced a significant reduction in office systolic blood pressure (SBP) from 164.6 mmHg to 142.0 mmHg after 3 months, indicating the efficacy of the DENEX™ system in managing resistant hypertension.

Early trials of renal denervation showed significant reductions in blood pressure, suggesting a potential benefit for treating hypertension.

However, later studies comparing renal denervation to sham procedures yielded neutral results, indicating that current evidence is insufficient to establish it as a standard clinical therapy for hypertension.

Renal denervation is a promising device-based procedure for treating hypertension, showing safety and efficacy in recent clinical trials with new-generation devices, although its clinical use remains debated.

The Italian Society of Arterial Hypertension recommends careful patient selection for renal denervation, considering factors like blood pressure, cardiovascular risk, medication adherence, and patient preferences, while emphasizing the need for further studies to validate these recommendations.

Renal denervation (RDN) significantly reduced renal vascular resistance in patients with drug-resistant hypertension and type 2 diabetes, particularly in those with elevated baseline renal resistive index (RRI ≥ 0.7).

While RDN did not significantly change estimated glomerular filtration rate (eGFR), it effectively lowered blood pressure by an average of -10.9 mmHg systolic and -5.5 mmHg diastolic after 12 months, indicating its potential as a treatment option for managing hypertension in this patient population.

In a study of 46 patients with drug-resistant hypertension, the multi-electrode ablation system for renal denervation led to significant reductions in blood pressure over 24 months, with office BP decreasing by an average of -29/-13 mmHg.

The procedure was found to be safe, with no new serious device or procedure-related adverse events reported, indicating that renal denervation can be a reliable treatment option for patients with difficult-to-treat hypertension.

The Vessix Renal Denervation System significantly reduced office blood pressure by an average of 24.7 mmHg and ambulatory blood pressure by 8.4 mmHg after six months in patients with resistant hypertension, demonstrating its efficacy.

The procedure showed a favorable safety profile, with no serious renal artery injuries or significant changes in renal function, as indicated by stable eGFR levels, although one case of renal artery stenosis required stenting.

Renal denervation therapy (RDN) has been found to be safe for patients with resistant hypertension, but its effectiveness in lowering blood pressure is variable and not significantly better than standard medical therapy.

Recent studies and ongoing trials are focusing on improving the procedural aspects of RDN and identifying patients who truly have treatment-resistant hypertension, which may help uncover potential benefits of this therapy.

In a review of 50 trials involving 5,769 subjects, the rate of renal artery adverse events following renal denervation was found to be very low, with only 0.45% of patients experiencing renal artery stenosis or dissection.

The annual incidence rate of stent implantation after renal denervation was just 0.20%, indicating that serious complications are rare, and most adverse events occurred within the first year after the procedure.
