Anti-CLL-1-ds-PBD [Investigative]
Discovered Using Cell Line-derived Xenograft Model
Click To Hide/Show 9 Activity Data Related to This Level
Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Tumor Growth Inhibition value (TGI) ≈ 47.85% (Day 11) Positive CLL-1 expression (CLL-1+++/++)
Method Description
Three human AML cell lines, were used to establish subcutaneous xenograft models for evaluation of anti-CLL-1-ds-PBD efficacy. When mean tumor size reached the desired volume (200 mm3), animals were randomized into groups of n = 8, each with similar mean tumor size. Four hours later, animals in each group were given a single intravenous dose of vehicle or ADC (0.25 mg/kg) through the tail vein.
