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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a new type of PET/CT scan that uses a radioactive tracer called FAPI to detect an aggressive form of colorectal cancer known as CMS4. The CMS4 subtype is linked to worse outcomes and may not respond well to standard chemotherapy. Researchers will scan 45 patients with colorectal cancer that has spread to the liver, then compare scan results with tissue samples to see if the scan can accurately identify CMS4. If it works, this imaging method could help doctors personalize treatment without needing multiple biopsies.

What this could mean

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

Active substance
[18F]-ALF-FAPI-74 (a radioactive tracer for PET/CT scans)
What this could lead to
If successful, this scan could provide a non-invasive way to identify the aggressive CMS4 colorectal cancer subtype, helping doctors choose more effective treatments for each patient.
What could go wrong
This is a small early-phase study with only 45 participants, so results may not apply to all patients. The scan's accuracy in detecting CMS4 is still unproven, and it is not yet a standard diagnostic tool.

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 45 people

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

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.

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: * Age ≥ 18 years. * Candidates for liver metastatectomy at the time of liver metastasis diagnosis as clinically indicated in the tumor board (RAKU). * Patients must have given written informed consent. * At least one liver metastasis should have a longest diameter of a least 1.5 cm as measured on routinely performed imaging (e.g. magnetic resonance imaging, CT-scan or ultrasound). This minimum diameter will guarantee sufficient tissue material for analysis and will prevent underestimation of \[18F\]-ALF-FAPI-74 uptake due to partial volume effects. * CRC patients who received prior treatment before clinical indication for surgical liver metastases resection (both synchronous and metachronous patients, as well as a re-resection of liver metastatic disease) are allowed to enter the study. This is because our prime interest is in the relation between FAPI uptake and the presence of CMS4 at the same point in time, which will likely not be biased by earlier therapies. * It is allowed for patients to receive concurrent radiofrequency ablation or other local treatments directed to other metastatic disease locations, if at least one liver metastasis of sufficient size is planned to be surgically removed and therefore available for tissue analysis. * It is allowed for patients to be treated with pre-surgical radiotherapy directed to the primary tumor (e.g. in rectal cancer patients). Exclusion Criteria: * Pregnancy. * Patients treated with a pre-surgical chemotherapy regimen that does not include a fluoropyrimidine.
