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 This study
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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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

People with acute aortic dissection face a high risk of dangerous inflammation and multiple organ failure after emergency surgery. Researchers are testing whether thymosin alpha 1, an immune-modulating injection, can reduce that risk. The trial enrolls 600 adults undergoing emergency surgery for acute aortic syndrome. Half receive thymosin alpha 1 every 12 hours during intensive care, and half receive standard care alone. The main measure is how well organs function over the first week after surgery.

What this could mean

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

Active substance
thymosin alpha 1, an immune-modulating injection
What this could lead to
If it works, thymosin alpha 1 could become a standard immune-support treatment after emergency aortic dissection surgery, helping patients avoid organ failure and death.
What could go wrong
This is an early-phase study, so it may not show a clear benefit. Thymosin alpha 1 can cause allergic reactions, and the trial excludes people who are allergic to it.
