Emerging Strategies for Rheumatoid Arthritis
Methotrexate Dose in Patients With Early Rheumatoid Arthritis Impacts Methotrexate Polyglutamate Pharmacokinetics, Adalimumab Pharmacokinetics, and Efficacy: Pharmacokinetic and Exposure-response Analysis of the CONCERTO Trial
Methotrexate (MTX) and adalimumab are well-recognized treatments of rheumatoid arthritis (RA), the efficacy of which may be driven by intracellular polyglutamates (PGs). The aim of this analysis was to characterize MTX PG concentrations and adalimumab pharmacokinetics in the CONCERTO trial. In addition, the relationships between MTX dose/pharmacokinetics, adalimumab pharmacokinetics, and efficacy were evaluated.Systematic Literature Review and Meta-analysis of Tumor Necrosis Factor–Alpha Experienced Rheumatoid Arthritis
The goal of this study was to compile all available evidence regarding the efficacy of tumor necrosis factor–α (TNF) inhibitors, non-TNF biologics, and tofacitinib for TNF-experienced patients who have rheumatoid arthritis (RA).Real-world Effectiveness of Biologic Disease-modifying Antirheumatic Drugs for the Treatment of Rheumatoid Arthritis After Etanercept Discontinuation in the United Kingdom, France, and Germany
The purpose of this study was to assess the real-world effectiveness of patients with rheumatoid arthritis (RA) who discontinued etanercept treatment and subsequently received another tumor necrosis factor α (TNF-α) inhibitor or a non–TNF-α biologic in the United Kingdom, France, and Germany.Clinical Outcomes Associated with Switching or Discontinuation from Anti-TNF Inhibitors for Nonmedical Reasons
This study evaluated clinical outcomes and health care resource utilization associated with nonmedical switching from or discontinuation of anti–tumor necrosis factor (TNF) therapies in US clinical practice.Tofacitinib Versus Biologic Treatments in Patients With Active Rheumatoid Arthritis Who Have Had an Inadequate Response to Tumor Necrosis Factor Inhibitors: Results From a Network Meta-analysis
Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This analysis compared the efficacy and safety of tofacitinib with biologic disease-modifying antirheumatic drugs in patients with RA and a prior inadequate response (IR) to tumor necrosis factor inhibitors (TNFi).Initial Experience With Tofacitinib in Clinical Practice: Treatment Patterns and Costs of Tofacitinib Administered as Monotherapy or in Combination With Conventional Synthetic DMARDs in 2 US Health Care Claims Databases
Tofacitinib is an oral Janus kinase inhibitor indicated for the treatment of rheumatoid arthritis (RA). Tofacitinib can be administered as a monotherapy or in combination with conventional synthetic disease-modifying antirheumatic drugs (DMARDs). This study describes RA patients’ characteristics, treatment patterns, and costs for those initiating tofacitinib treatment as monotherapy or combination therapy, using US claims data from clinical practice.Treatment Patterns, Direct Cost of Biologics, and Direct Medical Costs for Rheumatoid Arthritis Patients: A Real-world Analysis of Nationwide Japanese Claims Data
The aims of this article were to characterize the patterns of treating rheumatoid arthritis with biologics and to evaluate costs using claims data from the Japan Medical Data Center Co, Ltd.Examining Time to Initiation of Biologic Disease-modifying Antirheumatic Drugs and Medication Adherence and Persistence Among Texas Medicaid Recipients With Rheumatoid Arthritis
Little is known about the transition from nonbiologic disease-modifying antirheumatic drugs (DMARDs) to biologic DMARDs or about individual nonbiologic DMARD use patterns among patients with rheumatoid arthritis (RA). This study examined time to initiation of biologic DMARDs and nonbiologic DMARD medication adherence and persistence among Texas Medicaid recipients with RA taking nonbiologic DMARDs.Cost-effectiveness of Tofacitinib in the Treatment of Moderate to Severe Rheumatoid Arthritis in South Korea
This study evaluated the cost-effectiveness of introducing tofacitinib, an oral Janus kinase inhibitor, to the treatment of Korean patients with rheumatoid arthritis (RA) and an inadequate response to conventional disease-modifying antirheumatic drugs.Impact of Switching From an Initial Tumor Necrosis Factor Inhibitor on Health Care Resource Utilization and Costs Among Patients With Rheumatoid Arthritis
Despite improved clinical outcomes for the majority of patients, nearly 30% of patients with rheumatoid arthritis (RA) who initiate tumor necrosis factor antagonist (anti-TNF) biologic agents fail to respond to their first-line anti-TNF and switch to another anti-TNF or a non-TNF biologic. How this change affects health care costs and resource utilization is unknown. We therefore compared RA patients taking first-line anti-TNFs who switched to a second anti-TNF versus those patients who switched to an alternate biologic.Medication Adherence and Attrition to Biologic Treatment in Rheumatoid Arthritis Patients
The objectives of this study were to assess medication adherence rate and attrition rate in first-time adalimumab (ADA) or etanercept (ETA) users in rheumatoid arthritis (RA) patients. This study also identified the risk factors associated with nonadherence and treatment abandonment.
