A phase II, randomized, double‐blind, placebo‐controlled study evaluating the efficacy and safety of MDX‐1100, a fully human anti‐CXCL10 monoclonal antibody, in combination with methotrexate in patients with rheumatoid arthritis

MDX-1100 was well tolerated and demonstrated clinical efficacy in RA patients whose disease responded inadequately to MTX. This is the first study to demonstrate clinical efficacy of a chemokine inhibitor in RA and supports the notion of a potential role of IP-10 in the immunopathogenesis of RA.
