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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing a new PET imaging agent called [68Ga]Ga-OncoACP3 that targets a protein called ACP3, which is found in prostate cancer cells. The study enrolls 50 men with suspected or confirmed high-risk prostate cancer, or suspected recurrence after treatment. Each participant receives a single intravenous injection of the imaging agent and then undergoes a PET/CT scan about an hour later. The study measures how well the scan detects cancer lesions and compares it with standard PSMA PET imaging in some participants.

What this could mean

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

Active substance
a radioactive imaging agent called [68Ga]Ga-OncoACP3 that targets prostate acid phosphatase (ACP3)
What this could lead to
If it works, this imaging could offer another way to find prostate cancer lesions, especially when standard PSMA PET scans miss them.
What could go wrong
This is a small, single-center study. The imaging agent may not detect lesions reliably, and results might not apply to all prostate cancer patients or to other hospitals.

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

Inclusion Criteria: * 1\. Voluntary participation and signed written informed consent before any study-specific procedures; 2. Male, aged 18 to 90 years; 3. Clinically suspected high-risk, histologically confirmed, or suspected recurrent prostate cancer after treatment; 4. Willing and able to comply with scheduled visits, treatment plans, laboratory tests, and other study-related procedures; 5. Expected survival time greater than 6 months; 6. Participants' partners agree to use reliable contraceptive measures (such as abstinence, sterilization surgery, oral contraceptives, injectable medroxyprogesterone acetate, or subdermal implants) during the study and for at least 6 months after the last dose of study drug. Exclusion Criteria: * 1\. Known or suspected allergy to \[68Ga\]Ga-OncoACP3 injection or any of its excipients; 2. Any severe unstable disease (e.g., severe cardiac, pulmonary, hepatic, or renal insufficiency) that, in the investigator's judgment, makes the participant unsuitable for the study; 3. Inability to complete PET/CT examination, including inability to lie flat, claustrophobia, or radiophobia; 4. Poor compliance or any other condition that, in the investigator's judgment, makes the participant unsuitable for the study; 5. Prior use of a radiopharmaceutical within less than 10 physical half-lives before study drug administration; 6. Currently participating in or planning to participate in any drug or device clinical trial during the study period.
