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 Results may not be published yet.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.

Summary

This early-phase trial tests whether injecting stem cells (mesenchymal stromal cells) into the hand and forearm muscles can safely help heal painful finger ulcers in people with scleroderma. The study includes 20 participants whose ulcers have not improved with standard treatments. The main goal is to check for side effects, but researchers will also look for signs of better blood flow and ulcer healing.

What this could mean

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

Active substance
mesenchymal stromal cells (stem cells)
What this could lead to
If it works, this could offer a new way to heal stubborn finger ulcers in people with scleroderma, reducing pain and preventing tissue loss.
What could go wrong
This is a very early, small trial (20 people) focused on safety first. It may not show clear benefit, and there are risks like injection-site reactions or worsening ulcers.
