Losatuxizumab (ABT-806) is an anti-EGFR monoclonal antibody. Losatuxizumab binds to EGFR with EC50s of 0.96 nM for EGFR wild-type, 0.09 nM for EGFRC271A,C283A, 0.12 nM for EGFRvIII, 0.66 nM for EGFR1-501. Losatuxizumab can be used for research of EGFR-expressing cancers[1][2].
Losatuxizumab (0.001 nM-100 nM) binds to EGFRvIII-expressing cell line U87MGde2-7[1].
Losatuxizumab inhibits EGF-mediated EGFR phosphorylation in a NR6 huEGFRC271A,C283A cell line, with an IC50 of 1.2 nM[2].
Lorigerlimab has antitumor activities in various wild-type EGFR-expressing squamous cell carcinoma xenograft model[1].
Lorigerlimab (40 mg/kg, i.p.) significantly inhibits growth of U87MGde2-7 tumor in mice[1].
Lorigerlimab (10 and 40 mg/kg, i.p.) prolongs survival and reduces levels of pEGFR in PDX GBM model (SN0207 tumor)[1].
