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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 early-phase trial tests whether a single dose of donor stem cells (OmniMSC-AMI) given directly into the heart arteries is safe for people who have just had a major heart attack. The study enrolls adults aged 20–80 with a specific type of heart attack (anterior STEMI) who are treated within 6 hours. Researchers will monitor side effects and measure heart function over time to see if the stem cells might help the heart pump better.

What this could mean

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

Active substance
OmniMSC-AMI (donor bone marrow stem cells)
What this could lead to
If safe and effective, this approach could help repair heart muscle after a heart attack and improve pumping function.
What could go wrong
This is a very early, small safety trial with only 10 people. It is not designed to prove the treatment works, and stem cell therapies carry risks like inflammation or arrhythmia.
