NCT ID NCT06051812

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
Registered, but not yet taking participants.
By invitation only

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.

Summary

This observational study follows 25 people with end-stage kidney disease who are receiving a living donor kidney transplant. Researchers want to see how protein in the urine (proteinuria) relates to blood flow in the native kidneys before and after transplant. They also check for changes in tiny blood vessels in the eye. The goal is to better understand why proteinuria often drops after transplant and how it might affect heart health.

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 help doctors better understand why proteinuria drops after kidney transplant and how it relates to heart risk.
What could go wrong
This is a small, early observational study with only 25 participants. It is not testing a treatment, so it will not directly change patient care.
