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
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 Results may not be published yet.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 This study
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 looked at whether a device called Vendys II, which measures blood vessel function by tracking finger temperature after a brief blood flow restriction, could be used in children and young adults (ages 6-26) undergoing stem cell transplants. The goal was to see if it was feasible to measure vascular health in this group. The study was terminated early and enrolled only 27 participants.

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 could provide a simple, non-invasive way to monitor blood vessel health in young transplant patients.
What could go wrong
The study was terminated early with only 27 participants, so results are limited. It only tested feasibility, not whether the device improves outcomes.

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