Trial Outcomes & Findings for Renal Denervation for Management of Drug-Resistant Hypertension (NCT NCT01505010)

NCT ID: NCT01505010

Last Updated: 2020-03-27

Results Overview

The primary endpoint deals with efficacy of renal denervation with regard to controlling blood pressure on ambulatory measurement. It consists of the baseline-adjusted between-group difference in the changes in 24-h systolic blood pressure. Because automated blood pressure monitors will be used, the assessment of the primary endpoint is blind.

Participant Flow

From 28 March 2014 until 11 May 2016, 3 Belgian centers screened 29 patients, of whom 4 did not meet the criteria to enter the run-in period. Of 25 remaining patients, 8 were not eligible for randomization. Of 17 eligible patients, 9 were randomized to control and 8 to RDN. Of the 8 patients randomized to intervention, two did not undergo RDN.

PRIMARY outcome

Timeframe: This endpoint has been assessed 6 months after randomization.

The primary endpoint for safety of renal denervation is the baseline-adjusted between group difference in the change of glomerular filtration rate estimated by using the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation.
