About this study

The purpose of this study is to evaluate changes in adrenal hormones during adrenal radiofrequency (RF) ablation.

Read the detailed description

Adrenal radiofrequency (RF) ablation has been increasingly used for the treatment of unresectable adrenal tumors. But one of the major complication is a increase in blood pressure. Hormonal release during RF ablation is considered the cause of hypertension. But there has been no evidence that adrenal hormones affects changes in blood pressure. In this prospective study, we evaluate the changes in adrenal hormones during RF ablation and clarify the cause of hypertensive crisis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Radiofrequency ablationProcedure or surgery

    Radiofrequency (RF) ablation was done after RF electrodes were placed in the adrenal tumor in the adrenal RF ablation group. RF ablation was done after RF electrodes were placed in the targeted abdominal tumors other than adrenal gland in the abdominal RF ablation other than adrenal gland group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Increase in Catecholamine

    Measured: One day

  2. Serum Cathecholamine Levels

    Measured: around one year

  3. Number of Participants With Hypertension During Adrenal or Non-adrenal Radiofrequency Ablation

    Blood pressure was monitored during radiofrequency (RF) ablation. The frequency of hypertension (systolic blood pressure of more than 200 mmHg) was evaluated and compared between the adrenal and non-adrenal (RF ablation other than adrenal gland) RF ablation groups.

    Measured: 1 week

Secondary outcomes (1)
  1. Increase in Cortisol

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Radiofrequency ablation in people with Adrenal Tumors, run by Mie University at 2 sites in Japan.

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 1 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 Apr 2015. 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 Japan. 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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Feb 2011). 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?

Increase in Catecholamine (time frame: One day). The study lists 3 primary outcomes in all. 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 28 Apr 2015.
