About this study
Official title: A Post-Market Study of Transcatheter Perivascular Renal Denervation for the Treatment of Hypertension Using the Ablative Solutions Inc. Peregrine System™ Infusion Catheter
The Ablative Solutions, Inc. Peregrine System Infusion Catheter is a catheter-based device which is intended to be used to ablate the afferent and efferent sympathetic nerves serving the kidneys. The catheter is inserted via the femoral artery, steered into the renal artery, and then delivers, by infusion from its distal end, a neurolytic agent. This targets the nerve bundles, which are in the adventitia - a sheath surrounding the artery. The aim is to reduce blood pressure in cases of hypertension, including seriously elevated blood pressure which does not respond to drug treatment. This study will evaluate the safety and performance of the device.
Read the detailed description
There is strong evidence in the published literature that the renal nerves are important contributors to hypertension, and that their ablation does not have adverse side-effects.
The literature provides technical, clinical and scientific evidence supporting the use of perivascular renal denervation for a carefully defined patient group.
An existing device (the Medtronic Symplicity catheter) was initially shown to be safe and effective for achieving perivascular renal denervation by delivery of radio-frequency energy. The results of early nonrandomized clinical studies (HTN-1, HTN-2) found that perivascular renal denervation by radio-frequency energy delivery was an effective therapy, associated with very low risks. In other contexts, denervation can also be safely and effectively achieved by neurolytic agents.
The ASI Peregrine System™ Infusion Catheter and the denervation procedure in general is similar enough to the Medtronic Symplicity catheter to enable the use of published data to establish the validity of the design concept of the Peregrine System and estimate the likely levels of risk of side effects. It can be concluded from the literature that the ASI Peregrine System™ will achieve percutaneous renal denervation with a low risk of procedural complications (comparable to accepted percutaneous interventional therapies) and without long-term impairment of renal artery or kidney function or other serious adverse events.
Previous premarket clinical trials have provided support for the safe and effective use of the Peregrine Catheter for the treatment of patients with hypertension. The Peregrine System Infusion Catheter is currently CE marked and the indication for use is "The Peregrine System™ Infusion Catheter is intended for the infusion of a neurolytic agent to achieve a reduction in systemic blood pressure in hypertensive patients." Based upon the literature and previous clinical data, chemical denervation is an appropriate treatment for the specified study population of adults who have hypertension despite taking at least 3 anti-hypertensive drugs of different classes including at least one diuretic.
The objectives of this post-market study are to collect additional safety and performance data pertaining to renal denervation by using dehydrated alcohol as a chemical neurolytic agent delivered into the adventitial/peri-adventitial area of the renal arteries for the purpose of renal denervation, using the Peregrine System™ Infusion Catheter, in patients with hypertension.
In order for the study to be valid, only one chemical neurolytic agent can be used. The Coordinating Investigator has chosen to use dehydrated alcohol (not less than 95% by volume) for therapeutic neurolysis, therefore all participating sites will use this agent.

Questions about this trial
What is this clinical trial studying?
A study testing Peregrine System Infusion Catheter in people with Hypertension, run by Ablative Solutions, Inc. at 10 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in Germany, Poland, Belgium, Czechia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 Sep 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Subjects With the Absence of Particular Events as Adjudicated by the CEC Through 1-month Post Procedure: (time frame: 1-month). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
