32ongoing imaging trials

Target note

Full name
Amino acid transporters (system L/LAT1, ASCT2, system xC⁻)
Nature
Amino acid analogues taken up by the transporters overexpressed in proliferating cells, without notable incorporation into proteins.
Normal expression
Low uptake in healthy brain, which gives excellent contrast for gliomas; pancreas, liver and muscles depending on the tracer.
Value
Brain tumors (diagnosis, delineation, recurrence versus radionecrosis), recurrent prostate cancer (fluciclovine).
Approaches
[18F]FET (Pixclara), [11C]methionine, [18F]fluciclovine (Axumin), [18F]FSPG (system xC⁻), labeled glutamine and tryptophan; FDOPA is classified separately.
Indications explored
Gliomas and brain metastases, biochemical recurrence of prostate cancer.
Points of caution
Inflammatory uptake possible; [11C]methionine needs an on-site cyclotron (20-minute half-life).
