NCT ID NCT07604922

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study will test two new non-invasive devices (HEMI and SPG-NINOX) that measure small blood vessel function in 165 adults. Participants include healthy volunteers and people with high blood pressure, type 2 diabetes, or chronic kidney disease. The goal is to see if these devices can detect early blood vessel changes linked to these conditions, without any needles or procedures.

What this could mean

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

What this could lead to
If successful, this study could lead to a simple, non-invasive way to detect early blood vessel damage in people with kidney disease, diabetes, or high blood pressure.
What could go wrong
This is an early observational study, not a treatment trial. The devices are still investigational, and results may not lead to a widely available test.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts
