↵* Trastuzumab protein dose = 50 mg.
↵† Calculations used averaged time–activity curves (8 patients) from our 111In-MxDTPA-trastuzumab study (9), which were normalized to averaged blood and organ uptake data from current 64Cu-DOTA-trastuzumab study (6 patients).
↵‡ Assumes 64Cu injected activity = 450 MBq, average in current study.
