Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 0.00% (Day 27) Positive CD30 expression (CD30+++/++); Negative CD70 expression (CD70-)
Method Description
An in vivo therapy experiments with c1F6-9a was undertaken in nude mice with subcutaneous Karpas 299 ALCL tumors. The animals (5 per group)were treated with a single intravenous dose of c1F6-9a at 3 mg/kg (mAb component) on day 14.
