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 Results may not be published yet.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

Summary

This study tested a special dressing coated with a spider-silk-like chemical (DACC) to see if it prevents infections after vascular surgery. Over 700 adults in the UK were randomly assigned to get either the DACC dressing or a standard one. Researchers checked for infections at 30 days and measured quality of life and cost-effectiveness.

What this could mean

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

Active substance
DACC-coated wound dressing (Leukomed Sorbact)
What this could lead to
If effective, this simple dressing could become a low-cost way to prevent infections after surgery, reducing complications and healthcare costs.
What could go wrong
This trial is completed but results may not show a clear benefit over standard care. The dressing only binds bacteria mechanically, so it may not work for all wound types or infection risks.
