| Bioactivity | Moxetumomab pasudotox (CAT 8015) is anti-CD22 immunotoxin containing an anti-CD22 Fv and Pseudomonas exotoxin. CD22 is a cell surface receptor expressed on a variety of malignant B-cells. Moxetumomab pasudotox can be used in the research of hairy cell leukemia (HCL)[1][2][3]. |
| Invitro | Moxetumomab pasudotox (0-10 mg/mL, 66 h) reduces cell viability of BCP-ALL cells (determined by Annexin-V negative)[3].The binding and internalization of MP/CD22 complexes is correlated with pre-B ALL cell line responses to MP[5]. |
| In Vivo | Moxetumomab pasudotox (300 mg/kg, i.v., every other day) prolongs median survival in 697 cell model (P < 0.0001)[3].Moxetumomab pasudotox (0.4 mg/kg, i.v. three doses, every other day) clears the bone marrow (BM) from acute lymphoblastic leukemia (ALL), but disease relapses from discrete BM-sites in NSG mouse model[4].
