WO2021147993A1 ADC-6 [Investigative]
Discovered Using Cell Line-derived Xenograft Model
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Tumor Growth Inhibition value (TGI) | ≈ 0.00% (Day 28) | Moderate TROP2 expression (TROP2 ++) | ||
| Method Description |
Conjugates of the exemplary anti-TROP2 antibodies were tested using an established xenograft model of NUGC4 cells implanted subcutaneous into SCID mice. Mice were randomized by body weight into treatment groups and treated once post cell inoculation with 10 mg/kg of one of the conjugates listed above or with PBS only.
