Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 81.28% (Day 22)
Method Description
Conjugates of the exemplary antibodies were tested using an established PDX model of esophageal squamous cell carcinoma cell implanted subcutaneous into SCID mice. Mice were randomized by body weight into treatment groups and treated once post cell inoculation with 10 mg/kg, i.v., QW*3 of one of the conjugates listed above or with PBS only.
In Vivo Model Esophageal squamous cell carcinoma PDX model (PDX: ES0204)
Experiment 2 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 88.81% (Day 22)
Method Description
Conjugates of the exemplary antibodies were tested using an established PDX model of prostate cancer cell implanted subcutaneous into SCID mice. Mice were randomized by body weight into treatment groups and treated once post cell inoculation with 10 mg/kg, i.v., QW*3 of one of the conjugates listed above or with PBS only.
