This post hoc analysis of pooled data from 21 clinical trials in the tofacitinib clinical trial programme highlights the importance of identifying known risk factors of RA-interstitial lung disease (ILD) in clinical practice.Citera, et al. investigated incidence rates of ILD – an extra-articular manifestation of RA – in patients with RA, receiving tofacitinib 5 or 10 mg BID and sort to identify potential risk factors for ILD in these patients....

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 der...

This study highlights the importance of accounting for known risk factors of RA-ILD in clinical practice. Interstitial lung disease (ILD) is an extra-articular manifestation of RA. The post-hoc investigated incidence rates of ILD in patients with RA, receiving tofacitinib 5 or 10 mg twice daily, and identified potential risk factors for ILD. This post-hoc analysis comprised a pooled analysis of patients receiving tofacitinib 5 or 10 mg twice daily or placebo from 21 Phase 1-4, and 2 long-term ex...

TOF 5 mg and 10mg BID demonstrated a consistent safety profile and sustained efficacy for up to 9.5 years in this open-label LTE ORAL Sequel study.TOF 5 mg and 10 mg BID demonstrated consistent safety (as monotherapy and combination therapy) and efficacy within this open-label LTE study of RA patients. As RA requires long-term treatment, it’s important to assess the long-term efficacy and safety of RA therapies to understand the potential lifelong impact on patient health and quality of life. Th...

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...

In this post hoc analysis, six Phase 3 studies were used to analyse the effect of glucocorticoids (GC) on the efficacy of tofacitinib (TOF) in patients with RA. Concomitant use of GC did not affect the clinical or radiographic outcomes of patients treated with TOF. Data from all six clinical trials were evaluated, with four studies (ORAL Scan, ORAL Standard, ORAL Sync and ORAL Step) being pooled for analysis. In these studies, MTX was used as a comparison and patients were required to maintain a...

Analysis of 19 studies involving the use of tofacitinib to treat RA showed that lymphoma incidence rate and type were consistent with expectations in the RA population as a whole, and did not increase with tofacitinib exposure time.Previous research has suggested that there is a link between the likelihood of developing malignant tumours and RA. Previously, it has been unclear whether the increased rates seen are due to the use of immunomodulatory therapies, such as tofacitinib, which are used a...

This analysis of exposure to tofacitinib, an oral JAKi for the treatment of RA, for up to 8.5 years allowed estimation of safety events with improved precision versus previous tofacitinib reports. Adverse events were generally stable over time; no new safety signals were observed compared with previous tofacitinib reports.Data were collated into an integrated safety summary of tofacitinib in adult patients with active RA, and included data spanning the tofacitinib clinical programme: from 2 Pha...

In this analysis examining haematological changes after tofacitinib (TOF) treatment in patients with RA from pooled Phase 3 and LTE studies, TOF decreased mean lymphocyte counts and slightly increased mean haemoglobin (Hb) levels. The Phase 3 population included patients from six trials (n=4271) of TOF 5- or 10 mg BID, placebo or active comparator up to 24 months. The LTE population (n=4858) included patients from two studies (of up to 84 months), who had participated in Phase 1, 2 or 3 TOF stud...
