About this study
Official title: Radiofrequency Ablation for Aldosterone-producting Adenoma in Patients With Primary Aldosteronism: Evaluation of the Blood Pressure Control and of Its Safety.
The aim of the study is to evaluate the novel use of adrenal radiofrequency ablation on a prospective cohort of patients with primary aldosteronism and unilateral adrenal adenoma concerning the efficacy on blood pressure control. The safety of the procedure is one of the secondary outcomes.
Read the detailed description
The prevalence of hypertension dramatically increased. Although most cases of hypertension are idiopathic, some cases have an identifiable cause. Primary Aldosteronism (PA) is the most common cause of secondary hypertension and can be cured by surgery if PA is due to unilateral unique adrenal adenoma. Then this cause is worth identifying it. The surgery despite its minimally invasive nature is limited by the need for general anesthesia, the risk of vascular or visceral injuries, hematomas and all the adrenal gland is mostly removed. Imaged-guided percutaneous adrenal radiofrequency ablation (ARF) offers a less invasive alternative therapeutic option. This local therapy is employed to treat solid neoplasms whereas its application on functional adrenal adenoma is less documented and only a few case series with limited sample size are published. The impact on blood pressure control is not clearly reported. ARF ablation works by delivering a high-frequency alternating current through a needle electrode. An ionic agitation occurs and generates frictional heat for cell destruction at a predictable temperature and volume. Patients with a conventional documented PA due to unilateral adrenal nod who consented to the study were hospitalized. Patients with PA due to an aldosterone-producing adenoma are included in the study.

Questions about this trial
What is this clinical trial studying?
A study testing Radiofrequency ablation in people with Primary Aldosteronism and Adrenal Adenoma, run by University Hospital, Toulouse at 2 sites in France.
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 5 inclusion and 9 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 4 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in France. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
mean day-time systolic/diastolic blood pressure (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02756754, which also lists 2 linked publications.
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 4 May 2026; AzTrials last refreshed its copy on 8 Nov 2026.
