Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 89.73% (Day 45) Positive ALPPL2 expression (ALPPL2+++/++)
Method Description
Nude mice were subcutaneously (s.c.) implanted with one million M28 cells. When the average tumor volume reached 250 mm3, the mice were randomized into three study groups and treated intravenously (i.v.) with M25ADCMMAF for 3 mg/kg very four days for a total of 5 doses.
In Vivo Model M28 CDX model
In Vitro Model Pleural malignant mesothelioma M28K cells CVCL_8106
Experiment 2 Reporting the Activity Date of This ADC [1]
