Digital PET/CT Using [Ga-68]PSMA vs. [F-18]NaF for Evaluation of Osseous Metastatic Involvement in Prostate Cancer Patients
- Conditions
- Prostate Cancer
- Interventions
- Registration Number
- NCT05527483
- Lead Sponsor
- University Hospitals Cleveland Medical Center
- Brief Summary
The purpose of this study is to evaluate a radioactive diagnostic study drug, which is called Gallium-68 Prostate Specific Membrane Antigen (\[Ga-68\]PSMA) for detection of bone metastasis in patients with prostate cancer.
For imaging the investigators will use a FDA approved imaging technology, digital Positron Emission Tomography (PET/CT). The investigators would like to know if digital PET/CT using \[Ga-68\]PSMA provides accurate information about the extent of bone metastases.
Therefore, the investigators will compare\[Ga-68\]PSMA PET/CT with Flourine-18 \[F-18\] Sodium Fluoride (NaF), which is a high resolution bone scan. \[F-18\]NaF is FDA approved and the reference standard for evaluating the presence of bone metastases.\[Ga-68\]PSMA is an investigational (experimental) drug that works by binding to Prostate Specific Membrane Antigen, which is overexpressed in prostate cancer. \[Ga-68\]PSMA is experimental because it is not approved by the Food and Drug Administration (FDA) at University Hospitals. However, FDA approval has been obtained for this study protocol by an Investigational New Drug (IND) application.
