Age and renal impairment (RI) had limited impact on the pharmacokinetics (PK) of filgotinib (FIL) but, in subjects with severe RI, exposure to the FIL metabolite was increased. FIL is a selective JAK1 inhibitor that is extensively, rapidly and proportionately absorbed after oral dosing from 50–200mg. Its major metabolite has a similar JAK1 selectivity profile but with reduced potency. In humans, exposure to the metabolite is higher by approximately 16–20 fold compared with the parent FIL. FIL an...

Baricitinib (BARI) in combination with MTX and concomitant csDMARDs was shown to be efficacious, regardless of corticosteroid use in RA patients. MTX is prescribed to most RA patients but concomitant csDMARDs and/or corticosteroids can be added. This study assessed the efficacy and safety of BARI in two arms; with/without corticosteroids and; with MTX only/MTX plus csDMARD/csDMARDs only. Baseline characteristics and adverse reactions were also compared. Data were pooled from two phase 3 studies ...

In this first clinical trial of filgotinib in patients with active AS, filgotinib significantly reduced disease activity, and the signs and symptoms of AS compared with placebo. The TORTUGA trial was a randomized, double-blind, placebo-controlled, Phase 2 trial, that enrolled 263 adult patients from 30 sites in seven countries. Patients with active AS and an inadequate response or intolerance to two or more NSAIDs were assigned 1:1 to receive filgotinib 200 mg or placebo once daily for 12 weeks....

In this first clinical trial of filgotinib in patients with PsA, filgotinib was effective in treating the signs and symptoms of active PsA across various disease manifestations.The EQUATOR trial was a randomized, double-blind, placebo-controlled, Phase 2 trial, that enrolled 191 adult patients from 25 sites in seven countries. Patients with active moderate-to-severe PsA and an insufficient response or intolerance to at least one csDMARD were assigned 1:1 to receive filgotinib 200 mg or placebo o...

Once daily baricitinib (BARI) inhibited radiographic progression of structural joint damage in patients with an inadequate response or intolerance to csDMARDs over 48 weeks.Current treatment goals aim to use DMARDs to inhibit structural joint damage and prevent long-term functional disability. In RA-BUILD¹, BARI was shown to significantly reduce radiographic joint damage progression in patients with active RA, with an intolerance or inadequate response to csDMARDs. Here, the authors report the l...

Tofacitinib (TOF) therapy reduced the progression of structural joint damage at 2 years, in patients of all disease states, compared with patients given methotrexate (MTX). Early intervention with DMARDs aim to prevent the development of future RA symptoms and inhibit the progression of structural damage to the joints. This post-hoc analysis uses data from two Phase 3 TOF studies, to examine the efficacy of early intervention with TOF on long-term radiographic outcomes and disease activity state...

This Chinese sub-population of patients with RA from ORAL Sync reported significant improvements in patient-reported outcomes (PROs), which were maintained up to 12 months from tofacitinib (TOF) treatment initiation. ORAL Sync was a randomised, Phase 3 study investigating TOF therapy in combination with csDMARDs in patients with active RA who had previously had an inadequate response to csDMARDs. To date, this is the only Phase 3 study of TOF in patients from China with RA. This analysis include...

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...

Patient-reported outcomes (PROs) vastly improved in the first 24 weeks post-initiation of tocilizumab (TCZ) therapies compared to methotrexate (MTX) monotherapy in the U-Act-Early trial.U-Act-Early was a two-year, treat-to-target study that compared the safety and efficacy of TCZ and MTX treatment strategies in DMARD-naïve patients with early RA. Sustained remission was classed as more effective in patients given TCZ monotherapy or combination therapy with MTX compared to MTX alone. TCZ therapie...
