Brief Summary
This phase II trial evaluates how well flotufolastat F 18 positron emission tomography (PET)/computed tomography (CT) imaging works to detect cancer that remains (residual) or that has come back (recurrent) after the completion of focal therapy for prostate cancer. Flotufolastat F 18 is a radioactive tracer that binds to prostate specific membrane antigen (PSMA), a protein over-expressed on prostate tumor cells. This allows for visualization of PSMA-expressing cells upon imaging. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, 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 the 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. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. Metabolic information means how much of the injected tracer is taken up by inflammatory tissue. Flotufolastat F 18 PET/CT imaging may be an effective and less invasive way to detect residual or recurrent disease in prostate cancer patients, compared to other methods.
Eligibility Criteria
Inclusion Criteria: * Men aged 18-90 at study enrollment * History of prostate cancer * Men who have had focal therapy (laser, cryotherapy, high-intensity focused ultrasound \[HIFU\], Tulsa Pro, irreversible electroporation \[IRE\], brachytherapy) within 6-36 months of enrollment Exclusion Criteria: * Contraindication to flotufolastat F 18 PET CT * Contraindication to ultrasound-guided prostate biopsy * Patients who are planned to have an x-ray contrast agent or other PET radiotracer \< 24 hours prior to the PET scan * Patients with castrate levels of testosterone secondary to androgen deprivation therapy * Inability to provide written informed consent * Known inability to remain still and lie flat for the duration of the PET/CT (about 30 minutes) * Any investigational agents within 42 days prior to the day of the first dose * Not able to understand and to follow study instructions and requirements.
