Analysis by Wells, et al. demonstrates long-term efficacy and tolerability of baricitinib 2 mg daily for up to 120 weeks in patients with rheumatoid arthritis.Using data from two completed phase III studies, RA-BEAM (csDMARD-IR patients) and RA-BEACON (TNFi-IR patients), and one ongoing long-term extension study (RA-BEYOND), results demonstrated that the long-term maintenance of clinically relevant treatment goals, including LDA, remission and normative physical function, is achievable with bari...

Filgotinib improved RA signs and symptoms, physical function, and inhibited radiographic progression. FIL 200mg plus MTX, but not FIL 100mg plus MTX showed non-inferiority to ADA plus MTX, based on DAS28(CRP) low disease activity. FIL was also well tolerated in RA patients with inadequate response to MTX.This 52-week, phase 3 randomised clinical trial (FINCH 1) evaluated the efficacy and safety of FIL in patients with RA randomised to FIL 200 or 100mg, ADA 40mg, or placebo, all with background M...

McInnes. I

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...

Clinical Outcomes in Patients Switched from Adalimumab to Baricitinib Due to Non-Response and/or Study Design: Phase III Data in Patients with Rheumatoid Arthritis

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)....

Thromboembolism with Janus Kinase (JAK) Inhibitor for Rheumatoid Arthritis: How Real is the Risk?

Drug Safety 2018 Jul;41(7):645–53

Current data suggests that JAK inhibitors may increase the risk of thromboembolism and pulmonary thrombosis (PT) in RA.Two JAK inhibitors – baricitinib (BARI) and tofacitinib (TOF) – are considered effective treatments for RA, however, there are concerns about the thromboembolic risks associated with them. In August 2017, the summary of product characteristics for BARI was revised to include a warning of developing DVT and pulmonary embolism (PE), with recommendations that BARI should be used wi...

2017 was a successful year for rheumatoid arthritis research, with some key advances in JAK inhibitors and IL-6 inhibitors, as outlined below. - Tofacitinib was suggested as a potential treatment for psoriatic arthritis, and NICE recommended tofacitinib as a treatment for moderate to severe rheumatoid arthritis - Baricitinib studies supported the potential use of baricitinib as a treatment for rheumatoid arthritis - Filgotinib Phase 2 studies suggested that filgotinib could be effective a...

This paper describes the patient-reported outcome (PRO) data collected in RA-BEAM, a Phase 3 study of baricitinib compared with both placebo and adalimumab in patients with RA and an inadequate response to MTX.PRO measures evaluated include health-related quality of life (HRQOL), physical function, disability, fatigue, sleep, mental health status, work productivity and work activity impairment. The RA-BEAM study demonstrated that patients treated with baricitinib experienced a greater improveme...

This open-label extension (OLE) of a Phase 2b randomised controlled trial (RCT) found that safety data collected over 2 years of treatment were generally consistent with previous findings for baricitinib in RA.In the RCT, baricitinib demonstrated significant improvement in disease activity compared with placebo and an acceptable safety profile in patients with RA and an inadequate response to MTX. Patients who completed the 24-week double-blind period of the study were eligible for the OLE. Rate...

The summary and accompanying slide deck have been developed in conjunction with the Genovese et al. study (Study 1) which examined ABT-494 in MTX-IR patients in order to compare and contrast the data. In these two Phase 2b studies, ABT-494 (a novel selective JAK-1 inhibitor) was shown to be effective in patients with active RA who were non-responders to MTX or at least one TNF inhibitor.Patients with active RA who had an inadequate response to MTX (study 1) or were refractory to or intolerant of...
