Spots Global Cancer Trial Database for RefleXion PET/CT Imaging Performance in Patients With Prostate Cancer

Study Description

Brief Summary: This clinical trial examines RefleXion Medical Radiotherapy System (RMRS) imaging to the standard of care (SOC) \[18F\]-DCFPyL positron emission tomography-computed tomography (PET-CT) imaging in patients with prostate cancer. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of a tracer, \[18F\]-DCFPyL, that binds to prostate specific membrane antigen (PSMA) on tumor cells. These PSMA tumor cells can then be identified on PET imaging. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. The RMRS is a imaging-therapy combination system that can plan for and deliver radiation therapy as well perform \[18F\]-DCFPyL PET-CT imaging. Comparing the imaging from the standard of care \[18F\]-DCFPyL-PET-CT with the \[18F\]-DCFPyL imaging from RMRS may help improve the quality of the imaging captured and determine if imaging can be done on the RMRS at the same time as planning for radiation therapy, which would reduce the number of scans needed to plan for radiation for prostate cancer.

Detailed Description: PRIMARY OBJECTIVE: I. To assess imaging performance of the fluorine F 18 piflufolastat (\[18F\]-DCFPyL) PET-CT subsystem on the X1 RMRS to detect lesions (primary and metastatic) in patients with prostate cancer. SECONDARY OBJECTIVE: I. To determine the feasibility of generating a biology-guided radiotherapy (BgRT) plan using X1 RMRS-acquired \[18F\]-DCFPyL PET data derived from the imaging-only session at the studied dose level. OUTLINE: Patients receive \[18F\]-DCFPyL intravenously (IV) and undergo \[18F\]-DCFPyL PET-CT over 30 minutes per standard of care (SOC). Patients with PET avid lesions then undergo a X1 RMRS PET-CT imaging-only session within 120 minutes of injection over 20-35 minutes. After completion of study, patients are followed up within 72 hours.
