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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests an experimental imaging agent called [68Ga]Ga-DWJ155 in adults with advanced cancers of the breast, lung, or stomach. The agent is designed to attach to tumor cells and show up on PET scans, helping doctors see where cancer has spread. Researchers will measure how well the agent highlights tumors compared to normal tissue, and they will also check its safety and how the body processes it. The study includes people with specific types of advanced breast cancer, non-small cell lung cancer, and gastroesophageal adenocarcinoma.

What this could mean

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

Active substance
A radioactive imaging agent called [68Ga]Ga-DWJ155 (also known as FKL480), given as an injection for PET scans
What this could lead to
If it works, this imaging agent could help doctors see tumors more clearly on PET scans, potentially guiding treatment decisions for several advanced cancers.
What could go wrong
This is an early phase 1 study with a small number of participants, so the imaging agent may not bind well to tumors or may not be safe. It is not yet known if it will improve cancer care.
