What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Renal denervationDevice
Also called Renal angiography
After a renal angiography according to standard procedures, subjects are treated with renal denervation (with sterile irrigated deflectable ablation catheter in renal artery), if without renal anatomic abnormality not detected by Renal CT/CTA.
Renal angiographyDiagnostic test
A renal angiography according to standard procedure.
| Study group | Role | What they receive |
|---|---|---|
| Renal denervation | Experimental | Renal angiography and renal denervation (with sterile irrigated deflectable ablation catheter in renal artery), and maintaining anti-hypertensive medications Receives: Device: Renal denervation; Diagnostic Test: Renal angiography |
| Renal angiography | Sham comparator | Renal angiography and maintaining anti-hypertensive medications Receives: Diagnostic Test: Renal angiography |

Questions about this trial
What is this clinical trial studying?
A study testing Renal denervation and Renal angiography in people with Primary Hypertension, run by Synaptic Medical Corporation at 1 site in China.
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 3 inclusion and 15 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: status not confirmed, as of the sponsor's last update on 27 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. 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. Some participants in this study may receive a placebo. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Jiayi Wang (+86-18511291205, jiayi.wang@synapticmed.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in daytime average systolic blood pressure as measured by 24-hour Ambulatory Blood Pressure Monitoring (time frame: from baseline to 3 months post-procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2018; AzTrials last refreshed its copy on 7 Nov 2026.
