Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 14.30% Positive IL13 expression (IL13+++/++)
Method Description
Cells were subcutaneously inoculated at a dose of 1,000,000 cells to the right flank region of each female nude mouse (Day 0). On the day 7 of grouping, the antibody-drug conjugate was intravenously administered at doses of 10 mg/kg, Q4d*4 to thetail of each mouse.
In Vivo Model HEY C2 CDX model
In Vitro Model Ovarian serous adenocarcinoma HEY C2 cells CVCL_X009
Experiment 2 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 42% Positive IL13 expression (IL13+++/++)
Method Description
Cells were subcutaneously inoculated at a dose of 1,000,000 cells to the right flank region of each female nude mouse (Day 0). On the day 7 of grouping, the antibody-drug conjugate was intravenously administered at doses of 3 mg/kg, Q4d*4 to thetail of each mouse.

Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Inhibitory Concentration (IC50) > 400 ug/mL Negative IL13 expression (IL13-)
Method Description
The MTS cell proliferation assay was performed as follows: CellTiter 96 Aqueous Non-Radioactive Cell proliferation Kit is used to determine the number of viable cells in cell proliferation assay. Tumor cells are plated at certain seeding densities in sterile 384-well black clear bottom Matrix plates at 40 uL per well and incubated overnight at 37°C in 5% CO2 before assaying.
