FOLH1 and neoplasm: The tumor uptake of both isomers is superior at all time points, compared to [177Lu]Lu-PSMA I&T: 4.4 ± 1.5%ID/g at 1 h, 6.2 ± 0.1%ID/g at 24 h and 1.0 ± 0.2%ID/g at 168 h.Despite the promising pharmacokinetics of [177Lu]Lu-rhPSMA-10.1, it is in general questionable to what extent these data, especially murine kidney uptake, is transferable to humans.
