TWEAKR-KSPi-ADC1 [Investigative]
Discovered Using Cell Line-derived Xenograft Model
Click To Hide/Show 1 Activity Data Related to This Level
Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 80.00% (Day 17) Positive CTLA4 expression (CTLA4 +++/++)
Method Description
To exclude anti-tumor effects based on the agonistic activity of the anti-TWEAKR antibody, a maximum dose of 5 mg/kg biweekly was chosen for investigating the anti-tumor activity of TWEAKR-KSPi-ADC1 in mice bearing CT26 tumors.
In Vivo Model CT26 CDX model
In Vitro Model Colon carcinoma CT26 cells CVCL_7254
