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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether 3D-printed molds, created from radiological images, can guide pathologists to sample the most informative parts of a removed tumor. Currently, sampling is done by eye, which may miss key regions. The study will compare samples taken with the mold to standard methods, looking at tumor grade and biomarkers. If it works, this could lead to more accurate diagnoses and personalized treatments.

What this could mean

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

Active substance
3D-printed tumor mold for tissue sampling
What this could lead to
If successful, this could improve the accuracy of tumor sampling, leading to better cancer characterization and more personalized treatments.
What could go wrong
This is a small, early-stage trial. The molds may not improve sampling accuracy as hoped, and the process may not be practical for routine use.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

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 2033

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.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

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

Show the full entry requirements

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

Inclusion Criteria: To be eligible for the study, the study candidate must: * be willing and able to give informed consent and give their written consent for the participation in the study (in case of a child (\<15-year-old), the consent is collected in an age-appropriate manner from the study candidate and their legal guardian(s)) * have a malignant or likely malignant tumor/tumors and undergo a surgical operation. Exclusion Criteria: To be eligible for the study, the study candidate cannot: * lack the capacity to provide informed consent (if a legal guardian objects to the participation of their child (\<15-year-old), the child is not eligible); * be at risk of having their standard of care treatment jeopardized by the study, in the opinion of their physician.
