huXBR1-402
huXBR1-402 (NBE-002 Antibody) is a high-affinity (Kd=5.8 nM) humanized chimeric rabbit/human monoclonal antibody that targets ROR1. huXBR1-402 specifically binds to the Ig/Fz domain epitope of human ROR1, directly inhibits the proliferation of ROR1-positive tumor cells and induces apoptosis of leukemia cells (apoptosis).

Biological Activity
Human
The antibody-drug conjugate huXBR1-402-G5-PNU inhibits proliferation of ROR1-positive mantle cell lymphoma cells[1].
huXBR1-402 binds to the Ig/Fz domains of human ROR1 with affinity comparable to the parent chimeric antibody XBR1-402[2].
Fully humanized huXBR1-402 specifically binds to human ROR1 expressed on ROR1+ MCL cell lines (JeKo-1, Mino), primary CLL cells[3].
HuXBR1-402 and its antibody-drug conjugate form huXBR1-402-G5-PNU mediate Fc-dependent ADCC and ADCP activity against non-proliferative primary CLL cells, but neither mediates CDC[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
huXBR1-402-G5-PNU (1 mg/kg; i.p.; 3 doses on days 1, 3, and 5 post-randomization; 1 week) increases survival by 3 weeks, stabilizes disease, reduces proliferative leukemic cells, and decreases splenic and peripheral tumor burden in immune competent huROR1-TCL1 CLL mice[3].
