Durability of Response to Tocilizumab Therapy in Rheumatoid Arthritis: Data from the US-Based Corrona Rheumatoid Arthritis Registry.

Introduction: Understanding the durability of response to treatment and factors associated with failure to maintain response in a real-world setting can inform treatment decisions for patients with rheumatoid arthritis (RA). The aim of this study was to analyze durability of response to tocilizumab (TCZ) and factors associated with durability among US patients with RA in routine clinical practice.

Methods: TCZ initiators in the Corrona RA Registry were included.

Methotrexate Discontinuation and Dose Decreases After Therapy With Tocilizumab: Results From the Corrona Rheumatoid Arthritis Registry.

Introduction: Similar outcomes have been observed between patients with rheumatoid arthritis (RA) responding to tocilizumab (TCZ) with methotrexate (MTX) who discontinued vs. continued MTX and between patients receiving MTX who added TCZ vs. switched to TCZ monotherapy.

Effectiveness of Tocilizumab in Patients with Rheumatoid Arthritis Is Unaffected by Comorbidity Burden or Obesity: Data from a US Registry.

Objective: Comorbidity burden and obesity may affect treatment response in patients with rheumatoid arthritis (RA). Few real-world studies have evaluated the effect of comorbidity burden or obesity on the effectiveness of tocilizumab (TCZ). This study evaluated TCZ effectiveness in treating RA patients with high versus low comorbidity burden and obesity versus nonobesity in US clinical practice.

Patterns of Prednisone Use in Patients with Rheumatoid Arthritis Initiating Treatment with Tocilizumab in Routine US Clinical Practice.

Introduction: Prednisone is frequently administered in combination with other therapies for the treatment of rheumatoid arthritis (RA); however, its chronic use is associated with an increased risk of comorbidities and mortality. The objective of this analysis was to evaluate changes in prednisone use among patients with RA treated with tocilizumab (TCZ) in routine US clinical practice.

Methods: TCZ-naïve patients in the Corrona RA registry who initiated TCZ were included.

Real-world Comparative Effectiveness of Tocilizumab Monotherapy vs. Tumor Necrosis Factor Inhibitors with Methotrexate in Patients with Rheumatoid Arthritis.

Introduction: Controlled clinical studies have shown that the efficacy of tocilizumab (TCZ) monotherapy is superior to that of tumor necrosis factor inhibitor (TNFi) monotherapy and comparable to that of TCZ plus methotrexate (MTX) for the treatment of rheumatoid arthritis (RA). This study compared the real-world effectiveness of TCZ monotherapy vs. TNFis plus MTX in US patients with RA.

Impact of Tocilizumab Monotherapy on Clinical and Patient-Reported Quality-of-Life Outcomes in Patients with Rheumatoid Arthritis.

Introduction: Tocilizumab (TCZ) monotherapy has been proven as an effective treatment for rheumatoid arthritis (RA) in clinical trials. However, there are limited data available regarding the effectiveness of TCZ monotherapy in real-world clinical settings in the United States. The objective of this study was to evaluate the impact of TCZ monotherapy on disease activity and patient-reported outcomes (PROs) in a US-based observational cohort of patients with RA seen in routine clinical practice.

Impact of rituximab on patient-reported outcomes in patients with rheumatoid arthritis from the US Corrona Registry.

To evaluate the impact of rituximab on patient-reported outcomes (PROs) in a US-based observational cohort of patients with rheumatoid arthritis (RA). Patients with active RA, prior exposure to ≥1 tumor necrosis factor inhibitor (TNFi) and who newly initiated rituximab were identified. Changes in PROs were assessed 1 year after rituximab initiation.

Safety of infusing rituximab at a more rapid rate in patients with rheumatoid arthritis: results from the RATE-RA study.

Background: As recommended in the current prescribing information, rituximab infusions in patients with rheumatoid arthritis (RA) take 4.25 hours for the first infusion and 3.25 hours for subsequent infusions, which is a burden on patients and the health care system.

Video capsule endoscopy to prospectively assess small bowel injury with celecoxib, naproxen plus omeprazole, and placebo.

Background & Aims: Data indicate that cyclooxygenase-2-specific inhibitors cause less gastroduodenal mucosal damage than nonspecific NSAIDS, but their effects on the small bowel mucosa are less well recognized. In a multicenter, double-blind, placebo-controlled trial with video capsule endoscopy (VCE) we prospectively evaluated the incidence of small bowel injury in healthy subjects treated with celecoxib compared to naproxen plus omeprazole.

Methods: We randomly assigned subjects with normal baseline VCEs to celecoxib 200 mg twice daily (n = 120), naproxen 500 mg twice daily plus omeprazole 20 mg once daily (n = 118), or placebo (n = 118) for 2 weeks.
