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 Results may not be published yet.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.

Summary

This trial tests whether a device called CUSA can remove lipomas, which are common benign fatty lumps under the skin, using a minimally invasive approach. Researchers plan to enroll 30 adults with lipomas larger than 1 cm on the trunk, limbs, or neck. The goal is to see if CUSA can completely remove the lipoma with smaller incisions, less scarring, and fewer recurrences compared to traditional open surgery.

What this could mean

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

Active substance
CUSA, a minimally invasive surgical device that uses ultrasound to break up and remove lipomas
What this could lead to
If it works, this could offer a less invasive way to remove lipomas, with smaller scars, faster recovery, and lower recurrence rates than open surgery.
What could go wrong
This is a small, early-stage study with only 30 participants. The device may not fully remove the lipoma, and there is a risk of complications such as bleeding, infection, or recurrence.
