Prostate Cancer Clinical Trial
Evaluation of PSMA Antagonist Produced by Two Different Methods
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.
Full 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.
Eligibility Criteria
Inclusion Criteria:
Subjects must meet all of the following criteria to be enrolled in this study:
Aged 21 years or older and below 80 years of age
Signed written informed consent and willingness to comply with protocol requirements
Histologically confirmed diagnosis of metastatic prostate cancer
Staging imaging exam confirming metastatic disease, e.g. total body MRI, or CT chest/abdomen/pelvis, 99mTc bone scan, NaF PET
Exclusion Criteria:
Laboratory values:
Serum creatinine >2.5 mg/dL
AST (SGOT) >2.5x ULN
Bilirubin (total) >1.5x ULN
Serum calcium >11 mg/dL
Presence of any other co-existing condition which, in the judgment of the investigator, might increase the risk to the subject.
Presence of serious systemic illness, including: uncontrolled inter-current infection, uncontrolled malignancy, significant renal disease, or psychiatric/social situations, which might limit compliance with study requirements.
Other severe acute or chronic medical condition(s) or laboratory abnormality(ies) that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and in the judgment of the investigator, would make the patient inappropriate for entry into this study.
Inability to lay on the scanner table for the required period of time, e.g., due to bone pain or claustrophobia.
