The binding activity was evaluated by flow cytometry on CD37-positive human diffuse large B-cell lymphoma cell line OCI-LY7 (DSMZ), the cells were suspended by the addition of each of the four antibody-drug conjugates or anegative control antibody-drug conjugate (hmAb-IgG1-DXd) produced using human IgG at each concentration, the MFI of antibody-drug conjugates at 100 ug/mL was measured.

Discovered Using Cell Line-derived Xenograft Model
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Tumor Growth lnhibition value (TGl) | < 30% | Positive CD37 expression (CD37+++/++) | ||
| Method Description |
CD37-positive human diffuse large B-cell lymphoma cell line SU-DHL-8 (ATCC) was subcutaneously inoculated at a dose of 5x106 cells to the right flank region of each five or six-week-old female SCID mouse (Day 0). On Day 7, the mice were randomly grouped. On the day of grouping, the antibodydrug conjugates hmAb-H11L11-DXd was intravenously administered at a dose of 1 mg/kg to the tail of each mouse. An antibody-drug conjugate (hmAb-IgG1-DXd) produced using human IgG was administered as a negative control at a dose of 3 mg/kg in the same manner as above. The long diameter and short diameter of the inoculated tumor were measured twice a week using electronic digital calipers, and the volume of the tumor was then calculated.
