Randomized Controlled Trial Multicenter StudyThe efficacy and safety of subcutaneous clazakizumab in patients with moderate-to-severe rheumatoid arthritis and an inadequate response to methotrexate: results from a multinational, phase IIb, randomized, double-blind, placebo/active-controlled, dose-ranging study.
Clazakizumab is a humanized monoclonal antibody that binds to the interleukin-6 (IL-6) cytokine. This study was undertaken to evaluate the efficacy and safety of clazakizumab in combination with methotrexate (MTX) or clazakizumab monotherapy versus MTX alone in patients with rheumatoid arthritis (RA) and an inadequate response to MTX. ⋯ In patients with RA and an inadequate response to MTX, treatment with clazakizumab in combination with MTX or clazakizumab monotherapy was well tolerated, and patients achieved significant improvements in disease activity, including higher rates of remission, as compared with patients receiving MTX alone.
