Imaging cancer using a novel PET agent targeting PSMA

A Study to Evaluate 68Ga-P3 PET/CT Imaging of PSMA Expression in Malignant Tumors

Not applicable Interventional Peking University First Hospital · NCT05887687

This study is testing a new imaging agent to see if it can help better detect certain cancers, especially prostate cancer, in patients who have already had a PET scan.

What this trial studies

This study investigates the use of a new PET imaging agent, [68Ga]P3, which targets prostate-specific membrane antigen (PSMA) to enhance the diagnosis of various malignancies. PSMA is highly expressed in prostate cancer cells and certain tumor blood vessels, making it a promising target for imaging. The trial will involve patients with confirmed or suspected cancer who have undergone a recent 18F-FDG PET/CT scan. The goal is to evaluate the effectiveness of [68Ga]P3 in identifying high-expression PSMA malignancies.

Who should consider this trial

Good fit: Ideal candidates include adults with confirmed or suspected cancer who have recently undergone an 18F-FDG PET/CT scan.

Not a fit: Patients who are pregnant, lactating, or planning to become pregnant within six months will not benefit from this study.

Why it matters

Potential benefit: If successful, this imaging technique could lead to more accurate diagnoses and better-targeted treatments for patients with PSMA-expressing tumors.

How similar studies have performed: Other studies have shown promising results with PSMA-targeted imaging agents, indicating a potential for success in this approach.
