What is the purpose of this trial?

This trial tests the Gemini System, a new treatment approach, to determine if it can safely lower high blood pressure by targeting multiple organs. Participants will either stop or continue their blood pressure medications while using this new approach. The trial seeks individuals with high blood pressure between 150/90 and 180/90 who struggle to control it, regardless of other heart risks.

As an unphased trial, this study provides a unique opportunity to explore innovative treatment options for managing high blood pressure.

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the Gemini System is safe for treating high blood pressure?

Research has shown that the Gemini System, which targets specific nerve pathways to lower blood pressure, has generally been well-tolerated in earlier studies. Initial data indicated that this method significantly reduced norepinephrine, a chemical linked to the body's stress response. This suggests it might effectively lower the activity of the part of the nervous system involved in stress.

While the safety of this system in humans is still under study, current information suggests it does not cause major side effects. This trial is in the "Not Applicable" phase, focusing on understanding the procedure's safety and effectiveness. Early results are promising, but more research is needed to ensure safety for everyone. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Gemini System for high blood pressure because it offers a novel approach through multi-organ denervation (MDN). Unlike traditional treatments, which typically rely on medications to manage blood pressure by targeting specific pathways like the renin-angiotensin system or calcium channels, the Gemini System uses a technique to disrupt nerve signals across multiple organs that contribute to hypertension. This innovative method could potentially provide more comprehensive and lasting blood pressure control, especially for those who either cannot tolerate medications or remain at high cardiovascular risk despite current treatments. With the Gemini System's unique mechanism, there is hope for better outcomes in managing high blood pressure, offering a fresh alternative for patients and healthcare providers alike.

What evidence suggests that the Gemini System is effective for high blood pressure?

Research has shown that using the Gemini System to treat multiple organs can effectively lower blood pressure. Studies indicate that this technique significantly reduces systolic blood pressure, with an average decrease of 12.1 mmHg, compared to a 7 mmHg drop in groups not receiving the treatment. This method targets and disrupts specific nerve pathways in several organs, improving blood pressure control. Early results suggest these reductions are significant and could benefit individuals with uncontrolled high blood pressure. In this trial, participants will be assigned to one of two arms: one where the Gemini System is used for patients off anti-hypertensive medications, and another where it is used for those on such medications. This approach has shown promise for both groups. ^{1 2 3 6 7}

Are You a Good Fit for This Trial?

The SPYRAL GEMINI Pilot Study is for adults with uncontrolled high blood pressure (office SBP ≥150 mmHg and <180 mmHg, DBP ≥90 mmHg, and a 24-hour average SBP of ≥140 mmHg but <170 mmHg). It's especially for those at high cardiovascular risk due to conditions like chronic kidney disease or diabetes.

What Are the Treatments Tested in This Trial?

Interventions

• Gemini System

Trial Overview This study tests the Gemini System's ability to safely perform multi-organ denervation. The goal is to see if it can lower blood pressure in people with hypertension who are not adequately controlled by their current treatment.
