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 Results may not be published yet.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 study is testing a new radioactive tracer called Al18F-octreotide for PET/CT scans in people with suspected or confirmed SSTR-positive tumors. The goal is to see if this tracer can more accurately detect these tumors. About 400 participants will receive an injection of the tracer before their scan. The study is currently recruiting.

What this could mean

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

Active substance
Al18F-octreotide (a radioactive tracer injected before PET/CT scans)
What this could lead to
If successful, this could provide a more accurate imaging method to detect and diagnose SSTR-positive tumors, helping guide treatment decisions.
What could go wrong
This is an early-phase diagnostic study, so the tracer may not prove more accurate than existing methods. Results may not apply to all tumor types.
