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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 tests a new type of ultrasound called super-resolution ultrasound (SRUS) to see if it can better tell the difference between benign (non-cancerous) and malignant (cancerous) swollen lymph nodes. About 779 adults with abnormal lymph nodes will receive an injection of ultrasound contrast agent, and the movement of tiny bubbles will be tracked to create a detailed map of blood vessels. The goal is to improve diagnostic accuracy and potentially reduce the need for invasive biopsies.

What this could mean

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

Active substance
Ultrasound contrast agent (Sonovue or Sonazoid)
What this could lead to
If successful, this could give doctors a more accurate, non-invasive way to tell if swollen lymph nodes are cancerous or not, reducing unnecessary biopsies.
What could go wrong
This is an early-stage diagnostic study, not a treatment. The technique may not prove more accurate than current methods, and results may not apply to all patients.
