Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (lC56) > 36000 ng/ml Negative 5T4 expression (5T4-)
Method Description
The 5T4 Cys-mutated mcMMAD and vcMMAD ADCs were each able to inhibit the growth of the 5T4 expressing cell lines MDAMB435/57T4 (a high 514 expressor) and MDAMB-468 (a HER2 resistant cell line with moderate 5T4 expression).
