RMD Open;3:e000496. doi: 10.1136/rmdopen-2017-000496

This post hoc analysis of 2 randomised controlled trials (RCTs) AMBITION and ADACTA found that tocilizumab monotherapy results in substantial and clinically meaningful improvements in patient-reported outcomes (PROs) over 24 weeks. PROs assessed included patient global assessment (PtGA), pain, HAQ-DI, Functional Assessment of Chronic Illness Therapy (FACIT-F) and Short-Form-36 (SF-36) physical component summary (PCS) and mental component summary (MCS) and eight domain scores. Tocilizumab (TCZ)...

Treatment Persistence and Clinical Outcomes of Tumor Necrosis Factor Inhibitor Cycling or Switching to a New Mechanism of Action Therapy: Real-world Observational Study of Rheumatoid Arthritis Patients in the United States with Prior Tumor Necrosis Factor Inhibitor Therapy

Wei W, Knapp K, Wang L, Chen C-I, Craig GL, Ferguson K Schwartzman S.
Adv Ther. 2017 Aug;34(8):1936-1952. doi: 10.1007/s12325-017-0578-8

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...

Comparison of the efficacies of abatacept and tocilizumab in patients with rheumatoid arthritis by propensity score matching

Kubo S, Nakayamada S, Nakano K, Hirata S, Fukuyo S, Miyagawa I, Hanami K, Saito K, Tanaka Y.
Annals of the Rheumatic Diseases. 2015 Aug 5. doi:pii: annrheumdis-2015-207784. 10.1136/annrheumdis-2015-207784. [Epub ahead of print]

This study compared the clinical outcomes at one year after the treatment either abatacept or tocilizumab in routine clinical practice. This study employed propensity score matching and demonstrated that abatacept and tocilizumab had comparable continuing efficacies, and that treatment with the drugs resulted in comparable clinical and functional remission rates. Additionally, abatacept and tocilizumab showed similar effectiveness with or without MTX. While clinical efficacies, including SDAI,...

Calprotectin more accurately discriminates the disease status of rheumatoid arthritis patients receiving tocilizumab than acute phase reactants

Calprotectin is a member of the S100 protein family that has strong pro-inflammatory effects that reflect local ongoing inflammation rather than systemic response, due to its release at local inflammation sites. High calprotectin levels have been found in SF and serum from RA patients and correlate with disease activity. This study analysed the accuracy of calprotectin compared to acute phase response in discriminating the clinical disease status of RA patients receiving TCZ. A clinical assessme...

Mechanism of Activation of Protein Kinase JAK2 by the Growth Hormone Receptor

Brooks AJ, Dai W, O’Mara ML et al.
Science 344, 2014; doi: 10.1126/science.1249783

Class I cytokine receptors are key regulators of many processes within the body. The receptors use the JAK-STAT signalling pathway, the deregulation of which causes it to become an important pathway in oncogenesis. Despite this, the processes responsible for JAK2 activation by class I receptors remains elusive. Previous studies using growth hormone and its receptor have led to a model of receptor activation where hormone induced receptor dimerization resulted in close proximity of the receptor ...
