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 Results may not be published yet.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

Summary

This early-stage trial tests whether a radioactive imaging agent called 111In-panitumumab can help find cancer that has spread to lymph nodes in people with head and neck cancer. The agent binds to a protein common on cancer cells and lights up on a special scan. About 30 participants will receive the agent before surgery, and doctors will compare the scan results with what they find during the operation. The main goal is to check safety and see if the agent improves detection of cancerous lymph nodes.

What this could mean

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

Active substance
Indium In 111 panitumumab (a radioactive imaging agent)
What this could lead to
If successful, this could improve the accuracy of detecting cancer spread to lymph nodes, helping surgeons remove the right nodes and potentially improving survival outcomes.
What could go wrong
This is an early phase I trial with only 30 participants, so it is too soon to know if the imaging agent works better than current methods. There may be side effects from the radioactive substance or the antibody.
