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 Results may not be published yet.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

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 trial tests whether infrared laser therapy can relieve pain and speed healing in people with chronic venous leg ulcers — slow-healing wounds on the lower leg caused by poor blood flow. About 20 adults with ulcers lasting more than four weeks will receive either real laser treatment or a sham light. Researchers will measure pain levels and wound size over time to see if the laser makes a difference.

What this could mean

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

Active substance
infrared laser therapy (Summus Laser)
What this could lead to
If it works, this could offer a non-drug way to reduce pain and speed healing of stubborn leg ulcers.
What could go wrong
This is a very small early trial with only 20 participants, so results may not apply widely. The laser is already cleared for muscle pain but not specifically for wound healing.
