Efficacy Data Tumor Growth Inhibition value (TGI) 0.00% Low CD37 expression (CD37+; CD37 MFI ratio=82)
Method Description
The in vivo antitumor activity of AGS-67E was evaluated in a CD37 positive NHL,CLL and AmL cell line xenograft models. Depending on the cell line,110e6 cells were injected into the flanks of individual SCID mice,and tumor volumes were allowed to reach 100 to 300 mm3. Animals and their tumors were size matched and randomized into treatment and control groups. Depending on the study,AGS67E and an isotype control ADC were dosed by i.v. bolus injection either at 0.25,0.75,1.5,or 3.0 mg/kg at biweekly (BIW) or weekly (QW) frequencies and for a total of 2 to 4 doses.

Animals and their tumors were size matched and randomized into treatment and control groups. Depending on the study,AGS67E and an isotype control ADC were dosed by i.v. bolus injection either at 0.25,0.75,1.5,or 3.0 mg/kg at biweekly (BIW) or weekly (QW) frequencies and for a total of 2 to 4 doses.
