Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The RPD Pilot trial will evaluate the safety and effectiveness of Verve Medical's RPDTM renal denervation system for hypertensive patients with uncontrolled blood pressure despite use of two medications at a therapeutic dose.

The novelty of the RPDTM system relates to its placement via natural orifice into the renal pelvis (bilaterally) for delivery of radiofrequency energy to ablate the nerves that pass through the outer wall of the renal pelvis, a technique referred to as renal pelvic denervation (RPD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Hypertensive patients frequently fail to have blood pressure optimally controlled, even with use of multiple medicines. The risk of chronically uncontrolled hypertension are substantial. Several clinical trials demonstrate the potential utility of renal denervation to improve blood pressure control as an adjunct to medications, yet the results of the technology and associated procedures have proven inconsistent. The RICH Pilot trial will evaluate the safety and effectiveness of Verve Medical's RPDTM renal denervation system for hypertensive patients with uncontrolled blood pressure despite use of two medications at a therapeutic dose.

The novelty of the RPDTM system relates to its placement via natural orifice into the renal pelvis (bilaterally) for delivery of radiofrequency energy to ablate the nerves that pass through the outer wall of the renal pelvis, a technique referred to as renal pelvic denervation (RPD).

Safety and effectiveness assessments will include measurement of ambulatory and automated office blood pressure, renal function, procedural complications and all adverse events. These randomized, double-blind, sham-controlled assessments will be conducted 2-, 6- and 12-months following the index procedure. Following completion of the 12-month assessments, sham treated subjects may receive open-label therapy if they meet the original inclusion/exclusion criteria, with all subjects followed for a total of 2 years.

Up until the Month 6 assessment is complete, anti-hypertensive medical therapy is not to be altered unless required by significant worsening of a hypertensive related disease or due to a hypertensive emergency. Following completion of the Month 6 assessments, blinded investigators will be permitted and encouraged to intensify anti-hypertensive medication(s) if clinically indicated, as described further in the protocol. Between years 1 and 2, investigators will continue to be encouraged to intensify anti-hypertensive therapy for subjects not at goal.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

The study is multi-center, randomized, double-blind and sham-controlled, with sham treated subjects undergoing a procedure that includes use of cystoscopic placement of a guidewire and sheath into one kidney and then the other, to mirror how subjects are treated with RPD.
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors
This study involves a hypertension study investigator and an operating endourologist. In the study, the hypertension investigator and their staff will be blinded to treatment through 12 months follow up. Equally, the patient will be blinded to the treatment. Masking will include isolation of medical records from the procedure and sensory isolation of the patient during procedure. All information will become available to the patient and hypertension team after the 12 months follow up.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

RPD arm

The Verve RPD™ system is used to perform renal pelvic denervation via the urinary collecting system for the treatment of hypertension. The system does so through the delivery of RF energy to the walls of the renal pelvis - delivered via natural orifice through the urinary tract. During the course of the study, patients will be on active medical therapy for their hypertension.

Group Type EXPERIMENTAL

RPD

Intervention Type DEVICE

Renal Pelvic Denervation

Active hypertension medical therapy

Intervention Type DRUG

Prespecified two medication regimen for control of hypertension

Sham arm

Sham procedure will include all steps employed in the renal pelvis denervation with exception of activation of the RPD™ Device. Sham procedure includes advancing guidewire, cystoscope and sheath to position within the renal pelvis, then deploying the RPD™ Device into the renal pelvis (within each kidney), keeping the device in place for 2 minutes (within each kidney) to simulate activation, and then withdrawing the device and sheath. During the course of the study, sham patients will be on active medical therapy for their hypertension.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

\- As recommended in ACC/AHA 2017 Guideline,2 subjects are to be taking one anti-hypertensive antagonizing the renin-angiotensin system, including ACE inhibitor, ARB or renin inhibitor. Second drug should either be a calcium channel blocker (amlodipine preferred) or a thiazide diuretic.
2. Stable antihypertensive medical regimen for at least 30 days.
3. Ambulatory mean daytime SBP ≥135 mmHg.
