What this trial is about
This early phase I trial evaluates whether a new imaging technique using flotufolastat F 18 (a type of prostate specific membrane antigen \[PSMA\] imaging agent) with positron emission tomography (PET)/computed tomography (CT) can be used to guide targeted prostate biopsies in men with prostate cancer. Flotufolastat F 18 is a radioactive imaging agent that binds to prostate tumor cells that express PSMA. This allows for visualization of PSMA-expressing tumor cells on imaging scans such as PET/CT. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, flotufolastat F 18. Because prostate cancer takes up flotufolastat F 18, it can be seen with PET. CT utilizes X-rays that track the body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in the body. The PET/CT scanner combines the PET and the CT scanners into a single device. A targeted prostate biopsy refers to using advanced imaging for guidance when taking samples (biopsies) of the prostate. This method can fuse (combine) PET/CT images with real-time ultrasound during a prostate biopsy. PSMA PET/CT scans have the potential for guiding prostate biopsies. Using image fusion technology, they can increase detection of prostate cancer by providing anatomical information and guidance during a prostate biopsy. Improved detection of prostate cancer using PSMA PET/CT guidance may better inform men and their clinicians about prostate cancer risk and management. This study attempts to determine how often prostate cancer is found when using PSMA PET/CT scan images during a biopsy versus the conventional magnetic resonance imaging-guidance.
Who can take part
Inclusion criteria
