Background：Eldelumab alternative identifier BMS-936557 is a fully human monoclonal antibody type IgG1 kappa that targets chemokine CXC motif ligand 10 CXCL10/Interferon-γ-inducible protein-10 IP-10. This drug was developed by Bristol-Myers Squibb and Medarex and designed for the treatment of Crohn's disease and ulcerative colitis. To date, eldelumab has been investigated as an induction and maintenance therapy in active Crohn's disease, and its induction treatment demonstrated trends towards clinical and endoscopic efficacy with no new safety signal in a phase IIa study. Meanwhile, inhibiting IP-10 activity through the use of the monoclonal antibody, eldelumab, demonstrated efficacy in patients who achieved high serum concentrations in this phase II, randomized, controlled, proof-of-concept study of moderate-to-severe ulcerative colitis.
