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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether a cell-free DNA liquid biopsy done at home can help screen for lung cancer in high-risk current and former smokers aged 50-80. Participants will either use the liquid biopsy or get a standard low-dose CT scan. The goal is to see if the home test encourages more people to get screened and catch lung cancer earlier.

What this could mean

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

Active substance
Cell-free DNA liquid biopsy
What this could lead to
If successful, this could make lung cancer screening easier and more accessible, catching the disease earlier in people at high risk.
What could go wrong
This is a small feasibility study, not a large trial. The liquid biopsy may miss some cancers or give false alarms, and it's not yet proven to be better than standard CT screening.

Participants

About 108 people

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

Started

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.
