Real-world evidence suggests that monotherapy and combination therapy tofacitinib is an effective intervention in RA with persistence and effectiveness comparable to bDMARDs. Despite recommendations from EULAR that bDMARDs and tsDMARDs be used in combination with csDMARDs for the treatment of RA, it is estimated that up to a third of patients take their medication as monotherapy.This post hoc analysis of data from the Australian OPAL study by Bird, et al. aimed to describe the real-world effecti...

TOF 5 mg and 10mg BID demonstrated a consistent safety profile and sustained efficacy for up to 9.5 years in this open-label LTE ORAL Sequel study.TOF 5 mg and 10 mg BID demonstrated consistent safety (as monotherapy and combination therapy) and efficacy within this open-label LTE study of RA patients. As RA requires long-term treatment, it’s important to assess the long-term efficacy and safety of RA therapies to understand the potential lifelong impact on patient health and quality of life.

the SURPRISE study group

The second-year results from the SURPRISE study show that low disease activity (LDA) can be maintained after discontinuation of tocilizumab with continued methotrexate after remission is achieved. Discontinuation of biologic agents in patients who have achieved remission or low disease activity (LDA) is desirable from a risk–benefit point of view. Compared with TNF inhibitors, little is known regarding TCZ-free remission or LDA, but studies indicate that only a small proportion of patients remai...

Treatment Persistence and Healthcare Costs Among Patients with Rheumatoid Arthritis Changing Biologics in the USA

Updated treatment guidelines recommend the use of different mechanism of action (MOA) therapies earlier in the treatment course. Clinical studies have revealed that this approach may be better than TNFi cycling, and may be more cost effective.This study of Commercial and Medicare Advantage claims data showed that patients who switched MOA had higher treatment persistence and lower healthcare costs than TNFi cyclers.After the first TNFi claim, patients either cycled to another TNFi (n=935) or swi...

Based on a Bayesian network meta-analysis (NMA) in patients with RA who previously showed failure with csDMARDs or biologics, discontinuation rates between tofacitinib (TOF) and biologics (TNFis, abatacept [ABT], rituximab [RTX] and tocilizumab [TCZ]) differed based on previous treatments and reasons for discontinuation.Data were collected from randomised controlled trials (RCT) found from literature searches from the Cochrane Central Register of Controlled Trials (CENTRAL) and MEDLINE. Disconti...

This retrospective, observational study used a real-world US clinical database to demonstrate greater effectiveness of switching to a therapy with an alternative mechanism of action (MOA) vs cycling between TNF inhibitors (TNFis) in patients in which TNFi therapy has failed.Between 1 April 2010 and 31 March 2015, a total of 613 of the observed patients failed a TNFi therapy and then either cycled to another TNFi therapy (54.2%) or switched to a therapy with an alternative MOA (45.8%). The most c...

Evaluation of Real-World Experience with Tofacitinib Compared with Adalimumab, Etanercept, and Abatacept in RA Patients with 1 Previous Biologic DMARD: Data from a U.S. Administrative Claims Database

Data were examined to compare patient characteristics, treatment patterns and costs in patients with RA receiving tofacitinib (TOF) or common bDMARDs (adalimumab [ADA], etanercept (ETN) or abatacept [ABA]) who had previously received a single bDMARD.This study analyses real-world data from two US claims databases between November 2012 and October 2014. Data were collected from a total of 1252 patients in the Truven Marketscan Commercial and Medicare Supplemental databases. Pre-index (12-months b...

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

Clin Ther. 2016 Mar 28. doi: 10.1116/j.clinthera. 2016.03.038 [Epub ahead of print]

Harnett et al.

This study analyzes data from two US claims databases between November 2012 and June 2014. It was designed to build upon knowledge from tofacitinib Phase 3 clinical trials providing clinical insights from independent sources on treatment patterns and costs for tofacitinib. Data were collected from 337 patients in the Truven Marketscan (TM) and 118 patients in the Optum Clinformatics (OC) databases. In this early experience cohort for tofacitinib, approximately 75% of patients had previously rece...

Cytokines in rheumatoid arthritis – shaping the immunological landscape

Nat Rev Rheumatol. 2016 Jan;12(1):63-8

McInnes I,

Buckley C,

Isaacs J

Cytokine-mediated pathways are central to the pathogenesis of rheumatoid arthritis and there has been great advances in understanding and clinical application in the last 20 years. McInnes and colleagues provide a timely and succinct overview the roles of cytokine families in the various phases and tissue compartments of this disease. They particularly review the combinatorial role played by cytokines in mediating the overlapping innate and adaptive immune responses associated with disease onset...
