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 Results may not be published yet.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.

Summary

This study tests a new type of CT scan that pauses during irregular breathing to get clearer images for lung cancer radiation planning. It involves 30 adults with lung cancer who will receive one extra scan during their usual treatment simulation. The goal is to see if this method reduces image artifacts and is tolerable for patients.

What this could mean

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

What this could lead to
If successful, this could improve the accuracy of radiation therapy planning for lung cancer by reducing image artifacts caused by irregular breathing.
What could go wrong
This is a small, early feasibility study with only 30 participants. The new scan may take longer and might not work well for people with very erratic breathing.

Participants

About 30 people

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

Started

May 2024

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * 18 years or older * Have the ability to give informed consent * A diagnosis of lung cancer with an indication for radiation therapy * Radiation therapy treatment involving the acquisition of a 4DCT scan for treatment planning Exclusion Criteria: * Pregnant women * Patients \<18 years * Patients who in the opinion of the treating physician could not tolerate the extra time on the CT couch for an extra scan
