OBJECTIVE Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the presence of autoantibodies and inflammation in multiple organ systems. Elevation of messenger RNA levels of interferon (IFN)-regulated genes (IRGs) has been described in the peripheral blood of SLE patients and has been associated with disease activity. The(More)
OBJECTIVE To investigate the efficacy and safety of ocrelizumab in patients with class III/IV lupus nephritis (LN). METHODS Patients were randomized 1:1:1 to receive placebo, 400 mg ocrelizumab, or 1,000 mg ocrelizumab given as an intravenous infusion on days 1 and 15, followed by a single infusion at week 16 and every 16 weeks thereafter, accompanied by(More)
BACKGROUND Systemic sclerosis (SSc) is a clinically heterogeneous, life-threatening disease characterized by fibrosis, microvasculopathy, and autoimmunity. Extensive nonclinical and clinical data implicate B cells in the pathogenesis of SSc. MEDI-551 is an investigational humanized monoclonal antibody that targets the B cell surface antigen CD19 and(More)
OBJECTIVES The efficacy and safety of sifalimumab were assessed in a phase IIb, randomised, double-blind, placebo-controlled study (NCT01283139) of adults with moderate to severe active systemic lupus erythematosus (SLE). METHODS 431 patients were randomised and received monthly intravenous sifalimumab (200 mg, 600 mg or 1200 mg) or placebo in addition to(More)
OBJECTIVE To assess the efficacy and safety of anifrolumab, a type I interferon (IFN) receptor antagonist, in a phase IIb, randomized, double-blind, placebo-controlled study of adults with moderate-to-severe systemic lupus erythematosus (SLE). METHODS Patients (n = 305) were randomized to receive intravenous anifrolumab (300 mg or 1,000 mg) or placebo, in(More)
OBJECTIVE To assess the pharmacodynamic effects of sifalimumab, an investigational anti-IFN-α monoclonal antibody, in the blood and muscle of adult dermatomyositis and polymyositis patients by measuring neutralisation of a type I IFN gene signature (IFNGS) following drug exposure. METHODS A phase 1b randomised, double-blinded, placebo controlled,(More)
