Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Half Maximal inhibitory Concentration (lC50) | 39.08 ng/mL | Positive Her2 expression (Her2+++/++) | ||
| Method Description |
Her2-Target expressing BT474 (breast cancer cells were seeded in 96-well cell culture plates for 24 hours before treatment. Cells were treated with 3-fold serially diluted antibody-drug conjugates or free compounds (i.e., no antibody conjugated to the drug) in duplicate at 12 concentrations.

| Experiment 2 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Half Maximal inhibitory Concentration (lC50) | 82.68 ng/mL | Positive Her2 expression (Her2+++/++) | ||
| Method Description |
Her2-Target expressing (BT474 (breast cancer), N87 (gastric cancer), MDA-MB-361-DYT2 (breast cancer)) or Her2-non-expressing (MDA-MB-468, HT29) cells, or CD33-target expressing HL60, HEL92.1.7, NB4 or CD33-non-expressing (Raji) cells were seeded in 96-well cell culture plates for 24 hours before treatment. Cells were treated with 3-fold serially diluted antibody-drug conjugates or free compounds (i.e., no antibody conjugated to the drug) in duplicate at 38 concentrations.
