OBJECTIVE Etanercept has been shown to improve the articular and cutaneous manifestations of psoriatic arthritis (PsA). In this study, we further evaluated the safety, efficacy, and effect on radiographic progression of etanercept in patients with PsA. METHODS Patients with PsA (n = 205) were randomized to receive placebo or 25 mg etanercept(More)
OBJECTIVE RANKL is essential for osteoclast development, activation, and survival. Denosumab is a fully human monoclonal IgG2 antibody that binds RANKL, inhibiting its activity. The aim of this multicenter, randomized, double-blind, placebo-controlled, phase II study was to evaluate the effects of denosumab on structural damage in patients with rheumatoid(More)
OBJECTIVE To determine the safety and efficacy of etanercept in a multicenter, randomized, placebo-controlled, double-blind trial of adults with moderate to severe active ankylosing spondylitis (AS). METHODS Patients (n = 277) were treated with either etanercept 25 mg (n = 138) or placebo (n = 139) subcutaneously twice weekly for 24 weeks. The primary(More)
OBJECTIVE To investigate the effect of etanercept therapy on radiographic progression in patients with ankylosing spondylitis (AS). METHODS Patients with AS who had previously participated in a 24-week randomized, double-blind, placebo-controlled trial of etanercept therapy were enrolled in a 72-week open-label extension. Radiographs of the cervical and(More)
OBJECTIVE To assess spinal inflammation by magnetic resonance imaging (MRI) before and after treatment with the tumor necrosis factor receptor fusion protein etanercept compared with placebo. METHODS As part of a recently published randomized, controlled trial, 40 patients with ankylosing spondylitis (AS) underwent MRI of the lower thoracic and lumbar(More)
OBJECTIVE To investigate the pathologic nature of features termed "bone erosion" and "bone marrow edema" (also called "osteitis) on magnetic resonance imaging (MRI) scans of joints affected by rheumatoid arthritis (RA). METHODS RA patients scheduled for joint replacement surgery (metacarpophalangeal or proximal interphalangeal joints) underwent MRI on the(More)
OBJECTIVES To report results of subgroup analyses of bone mineral density (BMD) and bone turnover markers from a randomised, double-blind, placebo-controlled, phase II study of denosumab, an investigational RANKL inhibitor, in patients with rheumatoid arthritis (RA) concurrently receiving treatment with bisphosphonates or glucocorticoids. METHODS Patients(More)
OBJECTIVE To examine the baseline demographic and disease characteristics that might influence improvement as measured by the Assessment in Ankylosing Spondylitis Response Criteria (ASAS 20) in patients with ankylosing spondylitis (AS). METHODS A multicenter Phase 3 study was performed to compare the safety and efficacy of 24 weeks of etanercept 25 mg(More)
OBJECTIVE To evaluate the continued safety and durability of clinical response in patients with ankylosing spondylitis receiving etanercept. METHODS 277 patients who had participated in a previous randomised, double blind, placebo controlled 24 week trial were eligible to continue in this open label extension study. All patients who enrolled in the open(More)
OBJECTIVE Clinical and radiographic responses were evaluated in patients with psoriatic arthritis (PsA) treated for up to 2 years with etanercept. METHODS Patients were previously randomized to receive placebo or etanercept in a double-blind study and chose to participate in the current open-label extension phase. All patients received etanercept 25 mg(More)
