2019 was another remarkable year in cytokine signalling. We can be optimistic that clinical practice for inflammatory arthritis will continue to improve, with promising long-term safety data supporting the use of established JAK inhibitors; tofacitinib and baricitinib, in addition to exciting phase III clinical data for filgotinib and newly approved upadacitinib. You can find the most notable papers, as selected by CSF Steering Committee Chair Professor Iain McInnes, with links to their respecti...

Peficitinib (PEF) 100 and 150 mg demonstrated robust clinical and structural efficacy in patients with RA who have an inadequate response to MTX. In Japan, two JAK inhibitors, TOF and BARI are currently available for RA patients with an inadequate response to conventional therapies. This randomized phase 3 study (RAJ4), assessed the efficacy and safety of two PEF doses in combination with MTX compared to PBO, in Japanese MTX-IR. Patients were randomized 1:1:1 to PBO, PEF 100 mg and 150 mg with M...

Switching from ADA to BARI without a lengthy washout period can be executed with acceptable safety and tolerability and was associated with maintained disease control. Switching therapies in RA is commonplace in myriad scenarios including inadequate responses, intolerances and patient preference. Assessing the safety and efficacy of new treatments such as BARI, in the context of use as a replacement therapy, is beneficial. A previous study (RA-BEACON) has demonstrated that safely switching from ...

Filgotinib is an orally administered, selective inhibitor of JAK1. Filgotinib has shown good efficacy and was well tolerated for the treatment of rheumatoid arthritis (RA) in Phase 2 studies.The objective of this Phase 3 study was to evaluate the efficacy and safety of filgotinib treatment in patients with RA who have had an inadequate response to methotrexate (MTX)....

UPA monotherapy showed statistically significant improvements in clinical and functional outcomes versus continuing MTX in MTX inadequate-responder patients with RA. Despite its proven effectiveness and safety, many patients are unable to tolerate MTX due to its side-effects. Therapies that can be used without concomitant MTX therefore, have an important place in RA management. In previous studies, UPA has shown efficacy in combination with stable background csDMARDs in RA patients who are DMARD...

In this integrated analysis, BARI showed an acceptable safety profile in Japanese patients with up to 3.2 years of exposure. Other than incidences of herpes zoster (HZ), no major differences were noted with BARI safety in Japanese patients with RA, compared to the patients in the integrated database.BARI has previously demonstrated significant clinical efficacy and acceptable safety. Japanese patients who participated in the BARI clinical development programme, were comparable to those from the ...

RA patients receiving TOF 5 or 10 mg BID plus MTX showed sustained clinical and radiographic treatment effects through months 12-24. The safety profile was consistent with previous TOF studies. The 12-month data from the ORAL Scan study have been previously reported. This report assesses durability of responses, including structural damage progression, and safety with TOF through 24 months. Patients were randomized 4:4:1:1 to receive TOF 5 or 10 mg BID, or PBO advanced to TOF with stable, backgr...

This review shows that changes in lymphocyte subsets were largely within normal reference ranges and were not associated with efficacy or safety end points. BARI is a selective JAK1/JAK2 inhibitor, approved for the treatment of moderate to severe RA. BARI treatment is associated with changes to circulating lymphocyte and lymphocyte subsets, however detailed analyses of these effects, and their relevance to efficacy and safety is lacking. This study investigated the changes in lymphocyte cell sub...
