Trial summary

This study investigates if a new prostate-specific membrane antigen (PSMA) drug makes prostate cancer easier to identify in positron-emission tomography (PET) imaging. If this works, prostate cancer treatments can be prescribed that match the location of the disease. PSMA is radiolabeled with Gallium-68 (Ga-68). Read more about this study

About this study

Official title: 68Ga PSMA-HBED-CC PET in Patients With Biochemical Recurrence

This study investigates if a new prostate-specific membrane antigen (PSMA) drug makes prostate cancer easier to identify in positron-emission tomography (PET) imaging. If this works, prostate cancer treatments can be prescribed that match the location of the disease. PSMA is radiolabeled with Gallium-68 (Ga-68). This means a participant receives a small dose of radiation from the drug - less than the annual radiation limit for a medical worker.

To test this new drug, participants will receive an injection of Ga-68 PSMA and then have a PET scan. This PET scan, and the reported results, will be entered into the medical record and shared with the treating oncologists.

Read the detailed description

This study evaluates PSMA-HBED-CC labelled with Gallium-68, abbreviated 68Ga PSMA. This is a radiotracer that attaches to receptors in the membrane of prostate cancer cells. The 68Ga PSMA is identified using a positron emission tomography (PET) scanner. It is believed that 68Ga PSMA will identify prostate cancer more precisely than normal imaging methods (MRI, CT, or ultrasound). Imaging is key to successful treatment - disease must be identified to be treated.

Men who have biochemical recurrence of prostate cancer are invited to test 68Ga PSMA. Participants undergo the 68Ga PSMA PET scan before further treatment. Clinical information, including any MRI, CT, or ultrasound imaging and biopsy/surgery information, will be used to determine if the 68Ga PSMA PET imaging was better than the standard imaging. The study team will collect this information for about 1 year after the PSMA scan.

Depending on findings, participants may be invited back for a second 68Ga PSMA scan. This is done if the first scan showed positive lymph nodes or soft tissue metastases but a surgery or biopsy result does not.

The results from these scans will be shared with the participant. Results will also be entered into the participant's medical record and shared with the treating oncologists.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Ga-68 PSMA-HBED-CC PET in people with Prostate Cancer and Prostatic Neoplasm, run by Michael Graham PhD, 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 8 inclusion and 6 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 12 Jul 2024. 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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 28 Jun 2024). 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?

Sensitivity of Ga 68-labeled PSMA-11 Positron Emission Tomography/Computed Tomography (PET/CT) for the Detection on a Per Patient Basis (time frame: Up to 12 months after 68Ga PSMA PET scan). 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 NCT03389451, which also lists 5 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 12 Jul 2024.
