What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

Most older Americans eat too much salt, which can raise blood pressure and harm the kidneys. This study tests whether a ketone supplement (a substance the body makes during fasting or exercise) can block those harmful effects. Thirty-five adults aged 60-85 will follow a high-salt diet for 10 days, with or without the supplement, to see if it keeps blood pressure and blood vessel function healthy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ketone supplement (beta-hydroxybutyrate)
What this could lead to
If it works, this could point toward a simple supplement to help older adults counteract the negative effects of a high-salt diet without needing to drastically change what they eat.
What could go wrong
This is a very small, short-term pilot study (35 people, 10 days). It is not designed to prove long-term benefits or safety, and results may not apply to everyone. The supplement may not work as well in humans as it did in rodents.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 35 people

The number the study aims to enrol. It can still change while the study runs.

Started

Mar 2025

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

50 to 85 years

Sex
