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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether injecting a near-infrared dye called indocyanine green (ICG) around a lung tumor can help surgeons see the tumor and the first lymph node it drains to during surgery. About 100 adults having lung surgery will receive the dye, and a special camera will detect it. The goal is to improve how accurately surgeons remove tumors and check for cancer spread.

What this could mean

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

Active substance
Indocyanine Green (ICG) dye
What this could lead to
If successful, this technique could help surgeons more precisely locate lung tumors and the first lymph node they drain to, potentially improving cancer staging and removal.
What could go wrong
This is an early-phase trial with only 100 participants, so results may not apply to all patients. The dye injection carries risks like allergic reactions, and the imaging may not always work as expected.
