Randomized Controlled Trial Multicenter Study
Efficacy and safety of ustekinumab in patients with active psoriatic arthritis: 1 year results of the phase 3, multicentre, double-blind, placebo-controlled PSUMMIT 1 trial.
Many patients with psoriasis develop psoriatic arthritis, a chronic inflammatory disease that afflicts peripheral synovial, axial, and entheseal structures. The fully human monoclonal antibody ustekinumab is an efficacious treatment for moderate-to-severe plaque psoriasis. We did a randomised, placebo-controlled, phase 3 trial to assess the safety and efficacy of ustekinumab in patients with active psoriatic arthritis. ⋯ Janssen Research & Development.

Review
Systemic lupus erythematosus and other autoimmune rheumatic diseases: challenges to treatment.
Increased understanding of the molecular mechanisms underlying the pathogenenesis of autoimmune rheumatic diseases has led to targeted biological treatments that modulate various aspects of the immune response. These new treatments, together with more judicious use of other immunosuppressive drugs, have resulted in marked improvements in morbidity and mortality. Although belimumab, an agent that inhibits B-cell survival, is the first drug to be approved by the US Food and Drug Administration for the treatment of systemic lupus erythematosus in 50 years, many other immunological targets are under investigation. We discuss the recent advances in the biological treatment of autoimmune rheumatic diseases, with a particular focus on systemic lupus erythematosus.
