This was an exploratory post hoc analysis of pooled data, from over 2000 patients in three Phase 3 studies of tofacitinib, which demonstrates an association between tofacitinib treatment and significantly greater improvements in fatigue, sleep, and health-related quality of life (HRQoL), compared with placebo.

Study shows that conversions from FACIT-F to PROMIS Fatigue are feasible and applicable for RA clinical trials.The Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-F), developed for use in cancer patients, has been validated for measuring fatigue in RA, and is often the tool used in European clinical trials; with 10 out of its 13 items being relevant for patients with RA. The Patient-Reported Outcomes Measurement Information System (PROMIS), developed and calibrated in the United ...

Analysis from the US Corrona RA registry has provided the longest-term real-world safety data for a JAK inhibitor to date. The analysis showed that the cohorts had similar adverse events, except for higher herpes zoster rates for tofacitinib initiators vs bDMARDs.Kremer JM, et al. analysed adult patients with RA newly initiating tofacitinib, or a bDMARD, to compare incidence rates of MACE, SIEs, HZ, malignancies and death. VTE data were also collected prospectively and assessed descriptively thr...

This analysis provides evidence that immune cell signalling pathways are important in RA. There were consistent differences between RA patients and healthy controls in IFNα, IL-6, IL-10 and GM-CSF+ IL-2 induced JAK/STAT signalling in multiple immune cell subsets.We know that RA is characterised by dysregulation of immune responses, but the exact cause is unknown. Recently, single-cell transcriptomics and mass cytometry confirmed the critical role of activated immune cells and fibroblasts, increa...

Approximately two thirds of long-term BARI treated patients achieved satisfactory humoral and functional responses to 13-serotype pneumococcal conjugate vaccine (PCV-13), whereas tetanus toxoid vaccine (TTV) responses were less robust. Both RA management guidelines and recommendations suggest vaccinating patients with RA against pneumococcal disease with PCV-13 and PPSV-23. The inhibition of the JAK mediated signal transduction pathways in RA treatment could diminish vaccine responses. Given the...

In this Phase 3 multicentre, randomised controlled trial in patients with active RA who were refractory or intolerant to previous biological treatment with at least one TNF inhibitor, sirukumab 50 mg every four weeks (Q4W) or 100 mg every two weeks (Q2W) was well tolerated and significantly improved signs and symptoms of disease.Patients were randomised 1:1:1 to placebo (n=294), sirukumab 50 mg Q4W (n=292) or sirukumab 100 mg Q2W (n=292), while continuing any concomitant DMARDs. Of the 878 rando...

The effect of tofacitinib on pneumococcal and influenza vaccine responses in rheumatoid arthritis

Ann Rheum Dis. 2015 Mar 20. pii: annrheumdis-2014-207191. doi: 10.1136/annrheumdis-2014-207191. [Epub ahead of print]

The increased risk of serious infection among RA patients means vaccinations against pneumococcus and influenza are recommended in this group of patients. Studies evaluating immune response to these vaccines in conjunction with DMARD therapy can provide clinicians with important information relating to things such as timing of vaccination.

This study aimed to assess the effect of tofacitinib on vaccine responses to PPSV-23 and the trivalent seasonal influenza vaccine in those whom tofacit...
