Fifty-six-week data suggest that upadacitinib could be a favourable long-term treatment option in patients with PsA who are refractory to biologic therapy. As the need for additional therapeutic agents that can effectively control disease activity continues, new data from a 56-week analysis of the oral reversible JAK1 inhibitor, upadacitinib, currently under investigation for the treatment of PsA, shows that efficacy of the drug is maintained over the duration of this study. Mease, et al. expl...

Assessment of radiographic progression in patients with rheumatoid arthritis treated with tofacitinib in long-term studies

van der Heijde D, Landewé RBM, Wollenhaupt J, Strengholt S, Terry K, Kwok K, Wang L, Cohen S.
Rheumatology (Oxford). 2021;60(4):1708-1716.

Long-term evaluation of tofacitinib has found limited progression of structural damage in patients with RA treated with tofacitinib for up to 5 years. Similar results were also observed for patients receiving tofacitinib monotherapy or combination therapy for up to 3 years. It is well known that inflammation in RA leads to structural damage over time, and therapies such as DMARDS have the ability to reduce inflammation whilst inhibiting the progression of structural damage. In this study, van...

Serum lipid level increases at month 3 following TOF treatment in PsA were consistent with observation in RA and psoriasis. The risk of CV disease is higher in people with PsA versus the general population – comparable with the well-documented rates seen in RA and diabetes. The reasons for this are not fully elucidated, but it has been suggested that there is an association between peripheral joint inflammation and lipid dysregulation in PsA.

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 pare...

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 repor...

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 sta...

This post-hoc analysis of two, Phase 3 studies, ORAL Start and ORAL Standard shows that early treatment response can predict long-term disease activity outcomes. EULAR recommendations suggest that treat-to-target strategies require regular target assessments with treatment approaches changed if targets are not reached at 6 months. To optimize this strategy, therapy outcomes should be known, and the relationship between short and long-term outcomes defined. The current analysis focused on the d...

The risk of cardiovascular (CV) disease among RA patients, compared with the general population is well documented. Alongside this, studies have been able to establish that risk factors in RA patients are not wholly associated with traditional CV risk factors such as such as diabetes mellitus, hypertension, smoking, and dyslipidemia, suggesting a relationship between parameters of RA disease activity and increased CV risk. Additionally, IL-6 has been linked with the development of coronary heart...
