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

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 Results may not be published yet.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.

Summary

This study looks at why people with type 2 diabetes often develop heart problems. Researchers will collect blood and urine from 90 volunteers—some with diabetes and heart disease, some with diabetes only, and some healthy—to study special cells called endothelial progenitor cells. The goal is to understand how these cells become dysfunctional and how inflammation plays a role, which could lead to better treatments in the future.

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 research could point toward new ways to prevent or treat heart disease in people with type 2 diabetes.
What could go wrong
This is an observational study, not a treatment trial. It is small (90 participants) and early-stage, so findings may not lead directly to therapies.

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