Pooled Study Data Show Blood Pressure Reduction With Renal Denervation System

ReCor Medical Inc. and its parent company, Otsuka Medical Devices Co. Ltd., are touting consistent and significant blood pressure (BP) reduction results across a wide range of patients with uncontrolled hypertension, including across differences in age, sex, baseline blood pressure, medication level and ethnicity. The results are derived from an analysis of pooled data from ReCor’s RADIANCE Global Clinical Trial Program: three prospectively powered, randomized and sham-controlled clinical trials which evaluated the endovascular Paradise Ultrasound Renal Denervation (uRDN) System in patients with uncontrolled hypertension. 

“Pooling the data from the RADIANCE program demonstrates that treatment with the Paradise uRDN System results in a consistent reduction in blood pressure across differing severities of hypertension. The consistent and clinically meaningful BP reduction across multiple patient groups increases our interest in the use of uRDN as a potential therapeutic option, when added to lifestyle modification and medications for our patients with uncontrolled blood pressure,” said study co-principal investigator Ajay Kirtane, professor of Medicine at Columbia University, Vagelos College of Physicians and Surgeons, and an interventional cardiologist at NewYork-Presbyterian/Columbia University Irving Medical Center.

The RADIANCE Pooled Analysis includes data from more than 500 patients randomized in the three studies from ReCor’s RADIANCE Global Program: RADIANCE-HTN TRIO, which studied patients with resistant hypertension, and RADIANCE-HTN SOLO and RADIANCE II, which studied patients with mild-moderate hypertension. The combined dataset showed an overall reduction in daytime ambulatory systolic BP in the uRDN group of -8.5 mmHg (p<0.0001) with a difference between treatment and sham at two months of -5.9 mmHg (p<0.0001), favoring uRDN. Blood pressure results were similarly positive in the 24-hour, nighttime, home, and office measures. A favorable safety profile was consistently observed following uRDN treatment across the studies.
 
“It is very important that the RADIANCE pooled analysis demonstrated a consistent blood pressure reduction in patients across a range of hypertension and both with and without antihypertensive medication, thus broadening the potential applicability of uRDN. Just as important, more than 50% of patients treated with uRDN in the pooled analysis either achieved daytime ambulatory BP control or had a greater than 10 mmHg decrease in daytime ambulatory systolic BP at two months, showing the potential benefits of uRDN as an element of a treatment regimen for patients with uncontrolled hypertension,” said study principal investigator Michel Azizi, professor of Medicine at Université Paris Cité, Hôpital Européen Georges Pompidou, Paris, France.
 
The RADIANCE Global Program is an international, multicenter, first-of-its-kind initiative designed to explore the benefits of ultrasound renal denervation in hypertension. The RADIANCE studies are double-blind, randomized, sham-controlled trials designed to provide information about the ability of the Paradise uRDN System to treat high blood pressure. All three studies in the RADIANCE Global Program were individually powered for efficacy with a primary endpoint of daytime systolic ambulatory blood pressure at two months, and all three met their primary efficacy endpoint with statistical significance at two months.
 
If maintained in the long-term, the blood pressure reductions demonstrated in the RADIANCE pooled analysis correlate to a potential 25% reduction in cardiovascular risk as shown in a meta-analysis of the cardiovascular benefits of antihypertensive medications. Hypertension is the leading contributor to disease burden worldwide, leading to increased cardiovascular morbidity and mortality, poorer quality of life, and increased cost to health systems.
 
The Paradise uRDN System bears the CE mark for the treatment of hypertension in Europe and is an investigational device in the United States and Japan.
