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 This study
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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 study collects wound fluid and tissue samples from 72 adults with chronic, non-healing ulcers, such as diabetic foot ulcers or surgical wounds. Researchers will use these samples in laboratory tests to see how different wound healing treatments, including INJECTHEAL hydrogel components, affect cell growth and bacteria. The goal is to find biomarkers that predict which treatments might work best for individual patients.

What this could mean

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

Active substance
INJECTHEAL hydrogel components and other wound healing therapeutics tested in laboratory assays using patient wound samples
What this could lead to
If successful, this could help identify which wound healing treatments work best for chronic ulcers and guide the development of more effective therapies.
What could go wrong
This is an observational study using lab tests, not a clinical treatment trial. Results may not directly translate to real-world healing outcomes, and the sample size is small.
