UCB presented new clinical data from studies of CIMZIA (certolizumab pegol) at the 2015 European League Against Rheumatism Annual Congress in Rome, Italy. The data showed CIMZIA's efficacy in treating adults with severe active axial spondyloarthritis, active psoriatic arthritis, and moderate to severe rheumatoid arthritis. UCB also released the first data from Phase 3 trials evaluating the safety and efficacy of using CIMZIA in combination with optimized methotrexate.
