What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested a new cone-beam CT scanner designed to take clearer images while patients are on the radiotherapy couch. 41 adults with head-and-neck, lung, breast, abdominal, or pelvic cancer each had one or two scans with the new device. The goal was to see if the images were good enough to help guide radiation more precisely, potentially reducing damage to healthy tissue.

What this could mean

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

Active substance
Novel cone-beam CT imaging device
What this could lead to
If successful, this scanner could provide clearer images during radiotherapy, potentially making cancer treatments more precise and reducing side effects.
What could go wrong
This was a small feasibility study with only 41 participants, so results may not apply to all patients or cancer types. The device is not yet proven to improve treatment outcomes.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

Who can take part

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

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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

Inclusion Criteria: * The patient will be treated with external beam photon radiotherapy at Maastro for head-and-neck cancer, stage I lung cancer, stage II-IV lung cancer, left breast cancer, or tumours in the abdominal or pelvic region. * Age ≥ 18 years * Ability to understand the requirements of the study and to give written informed consent, as determined by the treating physician * Provision of written informed consent Exclusion Criteria: * Patient is pregnant
