A Phase I Study: PET Imaging of Cancer Patients Using [18F] 4-L-Fluoroglutamine (2S,4R)
Interventional
Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic
pharmacokinetic profiles
The trial-design follows standard guidelines on collecting pharmacokinetic (PK) data for investigational radioactive drugs.1, 29-36 Animal [18F] 4-L-of [18F] 4-L-Fluoroglutamine (2S,4R). Fluoroglutamine (2S,4R) PK data provided a basis for the trial design. Sampling time-points were chosen (1) by anticipated exponential PK; with (2) allometry-based interspecies extrapolation of time-scales.37 As data is available from the first patients, suitability of the time-points will be re-examined. Blood samples will be centrifuged and the plasma pipetted, weighed and counted to determine the plasma time activity concentration curves (% injected dose/liter), as well as for metabolite analysis of the [18F] 4-L-Fluoroglutamine (2S,4R) compound (by radio-HPLC or other fit-forpurpose methodology).
