wO2023232144A1ADC-1 [Investigative]
Discovered Using Cell Line-derived Xenograft Model
Click To Hide/Show 1 Activity Data Related to This Level
Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth lnhibition value (TGl)
115.07%
Positive ErbB2/HER2 expression (ErbB2/HER2+++/++)
Method Description
In the ErbB2/HER2 high expression NCI-N87 CDX xenograft model, ADC-1 was administered at a dose of 3 mg/kg for five consecutive weeks. Compared with the control group, ADC-1 treatment group displayed significant suppression of tumour growth with an TGI of 115.07 % and T/C of 6.57%.

Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (lC50)
0.04636 nM
Positive ErbB2/HER2 expression (ErbB2/HER2+++/++)
Method Description
The ErbB2/HER2 positive cells were cultured overnight with ADC-1 or antibody mAb-1 at different concentrations (10, 3.3, 1.1, 0.37, 0.12, 0.041, 0.014, 0.0046, 0.0015, 0.00051nM) Or different concentrations of MMAE (monomethyloratin E) (30, 10, 3.3, 1.1, 0.37, 0.12, 0.041, 0.014, 0.0046, 0.0015nM); The ErbB2/HER2 negative cells cultured overnight were added with ADC-1 or antibody mAb-1 at different concentrations (100, 10, 3.3, 1.1, 0.37, 0.12, 0.041, 0.014, 0.0046, 0.0015nM) Or different concentrations of MMAE (30, 10, 3.3, 1.1, 0.37, 0.12, 0.041, 0.014, 0.0046, 0.0015nM); Puromycin with a final concentration of 5uM was added to the control group. Continue warming at 37°C for 72~120h. 3) Remove the cell plates from the 37°C cell incubator and balance for about 30 minutes to room temperature. Each well is supplemented with 100uLCellTiter Glo reagent, the oscillator oscillates for 2min and then stands at room temperature for 10min away from light. The luminescence value (RLU) is measured.
