About this study

Official title: 18F-FACBC PET-CT for the Detection and Staging of Recurrent Prostate Carcinoma (CA129356-01).

Hypothesis:Anti-[18F]FACBC PET-CT will adequately detect local and extraprostatic recurrence, and lead to better characterization of disease status in restaging patients.

This is a study that will test a compound (chemical substance) that has a small amount of radioactivity attached to it. This substance has a natural tendency to go to prostate tissue. The substance is called [18]FACBC and it is given in the form of an injection into a vein. After the substance reaches the prostate, scans called PET or Positron Emission Tomography, are done. This is similar to having CAT scans or x-rays. Usually a compound called [18]FDG is used for PET scans but this substance is eliminated by the kidneys and cannot reach the prostate. This substance called [18]FACBC is not eliminated by the kidneys and may allow tumors in the prostate to be seen better. It is sometimes difficult to tell if a growth on the prostate is cancer with scans or x-rays that are usually done.

Anti-[18F]FACBC PET-CT will be compared to ProstaScint (In-capromab pendetide) which is the conventional imaging for prostate cancer. Investigators will be blinded of the intervention.

This study will look at how the [18]FACBC goes into the prostate tissue and determine its ability to detect recurrent prostate cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FACBCDrug

    Also called Fluciclovine

    Anti-3-[18F]FACBC is an investigational positron emission tomography (PET) radiotracer being studies given intravenously prior to PET scan

  • ProstaScinctOther

    Also called In-Capromab Pendetide

    ProstaScint (In-Capromab Pendetide) is used to image the extent of prostate cancer in standard practice. Capromab is a mouse monoclonal antibody which recognizes prostate specific membrane antigen from prostate cancer cells and normal prostate tissue. It is given intravenously prior to undergoing CT imaging.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing FACBC and ProstaScinct in people with Prostate Cancer, run by David M. Schuster, MD at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Aug 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With True Positive Scans Within the Prostate Bed (time frame: Up to 5 years). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00562315, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jun 2016.
