The half maximal inhibitory concentrations of anti-HER2-ADC on SK-OV-3, NCI-N87, SK-BR-3, Calu-3, HCC1954, BT-474 tumor cell lines had been 46 pmol/L, 17 pmol/L, 17 pmol/L, 161 pmol/L, 125 pmol/L, 50 pmol/L, respectively. Anti-HER2-ADC acquired a dose reliant Uridine diphosphate glucose antitumor activity in every the HER2 positive xenograft mouse versions. In NCI-N87 xenograft tumor model, the same dosage of anti-HER2-ADC demonstrated better anti-tumor activity weighed against ado-trastuzumab and trastuzumab emtansine, and its comparative tumor proliferation prices had been about 1/30 to 1/20 of both. In HCC1954 xenograft tumor model, the entire regression from the tumor was noticed. Needlessly to say, anti-HER2-ADC acquired no tumor inhibitory results on MDA-MB-468 xenograft versions with low HER2 appearance. The antitumor actions of anti-HER2-ADC in HER2 positive xenograft tumor versions were exactly like or much better than the actions of ado-trastuzumab emtansine.
