NCT ID NCT05423197

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
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 Results may not be published yet.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 This study
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This status has not been confirmed recently, so it may be out of date.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 Phase II trial investigates whether an experimental imaging agent called 89Zr-panitumumab can better identify metastatic lesions in people with head and neck squamous cell carcinoma. Participants receive the agent intravenously and then undergo PET/CT imaging, which is compared to standard FDG-PET/CT scans. The goal is to see if this new tracer improves sensitivity and specificity in detecting cancer spread, potentially leading to more accurate staging and treatment planning.

What this could mean

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

Active substance
89Zr-panitumumab, an investigational imaging agent given intravenously, plus a small oral dose of panitumumab
What this could lead to
If successful, this imaging approach could improve detection of cancer spread in head and neck cancer, guiding more accurate staging and treatment decisions.
What could go wrong
This is an early Phase II study with a small number of participants. The imaging agent may not reliably distinguish cancer from other lesions, and there are risks from radiation exposure and potential allergic reactions.
