About this study
Official title: Hemodynamic and Biological Effects of Fludrocortisone and Hydrocortisone, in Healthy Volunteers With Aldosterone Induced Suppression
Septic shock (associated with relative adrenal insufficiency) is characterized by decreased arterial responsiveness to catecholamines. The association of hydrocortisone and fludrocortisone has demonstrated an improvement in survival in septic shock patients. If hydrocortisone has shown to increase vascular responsiveness, the role of fludrocortisone remains to be elucidated. The purpose of our study is to investigate the effect of a physiological dose of fludrocortisone and/or hydrocortisone on phenylephrine-mean arterial pressure dose-response relationship in healthy volunteers with aldosterone suppression induced by intravenous sodium loading.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Fludrocortisone and Hydrocortisone in people with Renin Angiotensin, run by Rennes University Hospital at 1 site 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 15 inclusion and 0 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: stopped early, as of the sponsor's last update on 2 Mar 2012. 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 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. 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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
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?
Phenylephrine-mean arterial pressure dose-response relationship (time frame: Between 1.5 and 3 hours after treatment). 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 2 Mar 2012; AzTrials last refreshed its copy on 8 Nov 2026.
