Trial summary

Fludrocortisone, in association with hydrocortisone, has demonstrated an improvement in survival in septic shock patients with relative adrenal insufficiency. However, the utility of low doses of steroids and in particular of mineralocorticoids in septic shock is still discussed. Read more about this study

About this study

Official title: Hemodynamic and Biological Effects of 3 Increasing Doses of Fludrocortisone in Healthy Volunteers

Fludrocortisone, in association with hydrocortisone, has demonstrated an improvement in survival in septic shock patients with relative adrenal insufficiency. However, the utility of low doses of steroids and in particular of mineralocorticoids in septic shock is still discussed.

The purpose of the investigators study is to investigate the effects of 3 increasing doses of fludrocortisone (100 μg, 200 μg, 400 μg) in order to determine which dose allows the best pressor response to phenylephrine in healthy volunteers, and simultaneously assess their respective hemodynamic and biological effects.

Read the detailed description

In a previous study (AFLUCO2) in healthy volunteers with saline-induced hypoaldosteronism, the investigators found that single doses of both hydrocortisone and fludrocortisone induced a significant decrease in the pressor response to phenylephrine, probably due to a rapid non-genomic vasodilatory mechanism, and that these effects were additive.

The investigators also showed that, at the doses used in septic shock, hydrocortisone induced more pronounced mineralocorticoid effects than fludrocortisone and also induced systemic hemodynamic effects whereas fludrocortisone did not.

The investigators now want to perform a dose-response study under normal conditions (ie without saline-induced hypoaldosteronism) and after repeated administrations, to determine the optimal dose of fludrocortisone that allows an increase in the pressor response to phenylephrine and to characterize its concomitant hemodynamic and biological effects.

This placebo-controlled, randomized, double-blind, cross-over, 4-periods (fludrocortisone 100 μg/day, 200 μg/day, 400 μg/day, or placebo) study aims to investigate hemodynamic and biological effects of fludrocortisone administered orally during 5 days, in healthy volunteers.

Each period will be separated from the next one by a washout interval of at least 14 days.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Fludrocortisone 100 μg, Fludrocortisone 200 μg and Fludrocortisone 400 μg in people with Healthy Volunteers, 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 6 inclusion and 7 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 29 Aug 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 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 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.

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 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?

Phenylephrine mean blood pressor dose-response relationship. (time frame: 1.5 hour after fludrocortisone administration). 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 29 Aug 2018.
