Quetmolimab
Based on 1 Customer Validation
Quetmolimab (E6011) is a humanized anti-Fractalkine (CX3CL1) monoclonal antibody. Quetmolimab binds to membrane-bound and soluble Fractalkine, neutralizes Fractalkine-induced migration of CX3CR1-expressing cells, mediates target-bound complex elimination from serum. Quetmolimab suppresses free soluble Fractalkine levels in cynomolgus monkeys, with target engagement linked to increased serum total Fractalkine concentration. Quetmolimab can be used for the research of Crohn’s disease, rheumatoid arthritis, and primary biliary cholangitis.

Quetmolimab (E6011) inhibits fractalkine-induced migration of human CX3CR1-transfected B300.19 mouse B-lymphocyte precursors, with a minimum active concentration of 3.2 ng/mL for 10% maximal suppression of free soluble FKN from baseline[1].
Quetmolimab binds to soluble human fractalkine with a mean equilibrium dissociation constant of 0.27 μg/mL[1].

Animal Model:Cynomolgus monkeys (median body weight 3.44 kg)[1]
-
Dosage:0.05-100 mg/kg
-
Administration:i.v.; single infusion
-
Result:Exhibited a triphasic elimination profile, with dose-dependent increases in exposure where area under the concentration-time curve (AUC) increased more than proportionally to dose.
Increased serum total FKN concentration, confirming target engagement.
Reached a maximum effect (EMAX) of 0.974, indicating near-complete suppression of free soluble FKN elimination at sufficient concentrations.
Unconjugated
The product can be reconstituted/diluted with sterile PBS or saline.
