Full Information of The Activity Data of The ADC(s) Related to This Linker
Trastuzumab-PNUEDAGly5 [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) | ≈ 100.00% (Day 60) | Positive HER2 expression (HER2 +++/++) | ||
| Method Description |
1,000,000 EMT6 mouse breast cancer cells expressing human HER-2 previously determined to be suitable for in vivo growth, were implanted into theright mammary fat pads of female Balb/c mice. Animals were treated onthe same day (day 13) and 7 days later (day 20) byintravenous injection of the reference ADC Kadcyla (15 mg/kg), Trastuzumab-PNU-EDA-Glys (1 mg/kg) or vehicle control.
