Spots Global Cancer Trial Database for Evaluation of PSMA Antagonist Produced by Two Different Methods

Study Description

Brief Summary: Patients with metastatic prostate cancer will undergo two protocol 68Ga-PET scans within 24-48 hours with 68Ga-PSMA-cyclotron and 68Ga-PSMA-generator radiotracers. The goal of the study is to evaluate repeatability and equivalence across the different 68Ga-PSMA production methods. This research study is being conducted to assess whether the PET/CT imaging results, as generated from the two different 68Ga production methods, are equivalent.

Detailed Description: Patients with metastatic prostate adenocarcinoma will be enrolled in the study and will undergo two 68Ga-Prostate Specific Membrane Antigen- Positron Emission Tomography (PSMA-PET) scans within 24-48 hours. The difference between the two scans is that the radiotracer used in each scan will be produced with a different method (68Ga-PSMA-cyclotron and 68Ga-PSMA-generator produced). The first scan will occur after a baseline clinical evaluation, which will include a history, physical, and baseline lab draw. After each scan, blood draws will be obtained. The purpose of this study is to evaluate equivalence of two processes to create 68Ga-HBED-PSMA and compare dosimetry, biodistribution and whole body excretion/ metabolism. Furthermore, the research team will perform dynamic analysis of the PET scans to investigate repeatability of whole-body 68Ga-PSMA-generator Ki Patlak imaging against that of conventional whole-body 68Ga-PSMA- SUV imaging and evaluate equivalence of whole-body 68Ga-PSMA Ki Patlak imaging between the two processes to create 68Ga-HBED-PSMA (68GA-PSMA-cyclotron vs. 68Ga-PSMA-generator). Patients will afterwards receive standard of care treatment and follow up imaging.
