NCT ID NCT05724264

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 Results may not be published yet.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 whether combining low-dose CT scans with blood-based biomarker tests can improve lung cancer screening in high-risk people. It will enroll 1,000 participants in Singapore, including both smokers and non-smokers. The goal is to see if this approach is practical and accurate for detecting lung cancer early.

What this could mean

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

Active substance
Low-dose CT scan and blood biomarker tests
What this could lead to
If successful, this could lead to better, more personalized lung cancer screening guidelines for both smokers and non-smokers in Singapore.
What could go wrong
This is an early feasibility study, not a treatment trial. It may not prove that screening improves survival, and false positives could cause unnecessary worry or procedures.

Participants

About 1,000 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Dec 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
