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 Results may not be published yet.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.

Summary

This study is testing a new type of PET/CT scan that targets a protein called ACP3 to find prostate cancer tumors. Researchers will compare it to standard PSMA/FDG scans in 100 adults with newly diagnosed or recurrent prostate cancer. The goal is to see if the ACP3 scan is more accurate at detecting cancer lesions.

What this could mean

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

Active substance
ACP3 PET/CT scan
What this could lead to
If successful, this could provide a more accurate imaging method for detecting prostate cancer, potentially improving diagnosis and treatment planning.
What could go wrong
This is an early-stage diagnostic study with 100 participants, so results may not apply to all patients. The new scan may not be more accurate than current methods.

About 100 people

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

Started

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

18 years and older

Sex

Male participants only

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: * Adult patients (aged 18 years or older); * Patients with newly diagnosed, highly suspected recurrence or previously treated metastases of prostate cancer (supporting evidence may include MRI, CT, tumor markers, and pathology report); * Patients who had scheduled both standard-of-care imaging (PSMA/FDG PET/CT) and ACP3 PET/CT scans; * Patients who were able to provide informed consent (signed by participant, parent or legal representative) and assent according to the guidelines of the Clinical Research Ethics Committee.
