Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 50.00% (Day 25) Positive SLAMF6 expression (SLAMF6+++/++)
Method Description
Tumours were induced subcutaneously by injecting NHT-34 cells in 100 uL of RPMI 1640 containing matrigel into the right flank of male Balb/c nude mice. Treatments were started when the tumors reached a mean volume of 200-300 mm3. Mice were randomized according to their individual tumor volume into groups and received a single i.v, 0.025 mg/kg ADC.
