Clin Rheumatol. 2022 Jan 1. Epub ahead of print doi: 10.1007/s10067-021-05908-z

Post-hoc analysis shows that dosing up from tofacitinib 5 to 10 mg BID is associated with improved efficacy for up to 12 months, versus staying on 5 mg BID, and dosing down from 10 to 5 mg BID is not generally associated with a significant loss of efficacy. Although clinical trials have generally shown no significant differences, in terms of efficacy and safety, when switching tofacitinib dose up or down, these per-protocol switches are not directly informative for clinical decision-making in da...

Rheumatol Ther. 2021. Epub ahead of print. doi: 10.1007/s40744-021-00390-0

This post hoc analysis provides the first detailed description of the management and outcomes of HZ events in tofacitinib RA and PsA clinical studies. While prior studies have characterised the increased HZ risk with JAKinibs, the clinical management of these events has not been detailed. To this end, Winthrop, et al. analysed data from 21 RA and 3 PsA clinical studies to evaluate how HZ events and their sequelae were clinically managed during the RA and PsA tofacitinib clinical development pr...

Incidence Rates of Interstitial Lung Disease Events in Tofacitinib-Treated Rheumatoid Arthritis Patients

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...

Long-term Radiographic and Patient-reported Outcomes in Patients with Rheumatoid Arthritis Treated with Tofacitinib: ORAL Start and ORAL Scan Post-hoc Analyses

Strand V, Kavanaugh A, Kivitz AJ, van der Heijde D, Kwok K, Akylbekova E, Soonasra A, Snyder M, Connell C, Bananis E, Smolen JS.
Rheumatol Ther. 2018 Dec;5(2):341-353. doi: 10.1007/s40744-018-0113-7

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...

J Rheumatol 2018 Feb; 45(2):177-87

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 ...

Lymphoma in the Tofacitinib Rheumatoid Arthritis Clinical Development Program

Mariette X, Chen C, Biswas P, Kwok K, Boy MG.
Arthritis Care Res (Hoboken). 2018 May;70(5):685-694. doi: 10.1002/acr.23421

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...

Cohen BS, Tanaka Y, Mariette X, Curtis JR, Lee EB, Nash P, Winthrop KL, Charles-Shoeman C, Thirunavukkarasu K, DeMasi R, Geier J, Kwok K, Wang L, Riese R, Wollenhaupt J.
Ann Rheum Dis 2017;76:1253-1262. DOI 10.1136/annrheumdis-2016-210457

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 P...

Analysis of Haematological Changes in Tofacitinib-treated Patients with Rheumatoid Arthritis across Phase 3 and Long-term Extension Studies

Schulze-Koops H, Strand V, Nduaka C, DeMasi R, Wallenstein G, Kwok K and Wang L.
Rheumatology 2017;56:46–57.

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 st...

Efficacy and safety of tofacitinib following inadequate response to conventional synthetic or biological disease-modifying antirheumatic drugs

Charles-Schoeman C, Burmester G, Nash P, Zerbini CA, Soma K, Kwok K, Hendrikx T, Bananis E, Fleischmann R.
Annals of the Rheumatic Diseases. 2015 Aug 14. doi:pii: annrheumdis-2014-207178.

This study evaluated the efficacy and safety of tofacitinib, an oral Janus kinase inhibitor, in patients with inadequate response to sDMARDs or bDMARDs. Findings from this study show both doses of tofacitinib were associated with improvements in efficacy parameters at month 3 versus placebo, and clinical response was numerically greater with bDMARD-naïve versus bDMARD-IR patients (95% CI overlapping). Safety parameters were generally similar; however, patients receiving glucocorticoids had ...

Tofacitinib, an oral Janus kinase inhibitor: analysis of malignancies across the rheumatoid arthritis clinical development programme

Curtis JR, Lee EB, Kaplan IV, Kwok K, Geier J, Benda B, Soma K, Wang L, Riese R.
Ann Rheum Dis. 2015 Apr 22. pii: annrheumdis-2014-205847. doi: 10.1136/annrheumdis-2014-205847. [Epub ahead of print]

The developments of certain malignancies associated with chronic inflammatory diseases such as RA is known to occur to a greater extent than that of the general population. It is also know that certain RA treatments can affect malignancy rates. As such, newer immunomodulatory agents, such as the JAK inhibitor tofacitinib, are closely monitored for safety events of special interest, including malignancies. This paper analyses pooled malignancy data from the tofacitinib RA clinical development...
