Official Title: A Phase I Study: PET Imaging of Cancer Patients Using (18F) 4-L-Fluoroglutamine (2S,4R) Purpose: This is a Phase I study. This study is the first time that a new experimental drug called 18FFluoroglutamine, or F-Glutamine, is being used in people. F-Glutamine is a drug designed to be used with PET scanners that can 'see' where F-Glutamine goes in the body, after its injected. PET scanners are one of the kinds of scanners you normally find in a hospital radiology department. The researchers have found that tumors in animals absorb F-Glutamine. The researchers believe that scans with F-Glutamine might be able to find tumors in patients. This first in-human study is being done to see how long F-Glutamine lasts in the blood, when it is given to people in tiny amounts by an injection, and to see where F-Glutamine goes in the body. If the results of this trial are good, then the study doctors plan to use F-Glutamine in another trial to see if scans with F-Glutamine are better for finding tumors compared to the standard types of scans that doctors use.
ACTIVE MOIETY
RESULTS: In vitro studies showed that both transformed 9L and SF188 tumor cells displayed a high rate of glutamine uptake (maximum uptake, 16% dose/100 .MU.g of protein). The cell uptake of (18)F-(2S,4R)4-fluoroglutamine by SF188 cells is comparable to that of (3)H-L-glutamine but higher than that of (18)F-FDG. The tumor cell uptake can be selectively blocked. Biodistribution and PET studies showed that (18)F-(2S,4R)4-fluoroglutamine localized in tumors with a higher uptake than in surrounding muscle and liver tissues. Data suggest that certain tumor cells may use glutamine for energy production. CONCLUSION: The results support that (18)F-(2S,4R)4-fluoroglutamine is selectively taken up and trapped by tumor cells. It may be useful as a novel metabolic tracer for tumor imaging.
