Wollenhaupt J, Lee EB, Curtis JR, Silverfield J, Terry K, Soma K, Mojcik C, DeMasi R, Strengholt S, Kwok K, Lazariciu I, Wang L, Cohen S.

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 ...

The Safety and Immunogenicity of Live Zoster Vaccination in Rheumatoid Arthritis Patients Before Starting Tofacitinib: A Randomized Phase II Trial

Winthrop KL, Wouters A, Choy E, Soma K, Hodge J, Nduaka C, Biswas P, Needle E, Passador MS, Mojcik C, Rigby W.
Arthritis Rheumatol. 2017 Oct;69(10):1969-1977. doi: 10.1002/art.40187

Patients with RA who started treatment with tofacitinib 2–3 weeks after being vaccinated against herpes zoster had similar varicella zoster virus (VZV)-specific humoral and cell-mediated responses to the live vaccine compared to patients who received placebo. In this Phase 2 study, humoral and cell-mediated immune responses were evaluated before receipt of live zoster vaccine (LZV) and at 2, 6 and 14 weeks after vaccination, having been randomised to tofacitinib 5 mg BID or placebo, 2&nda...

Efficacy and Safety of Tofacitinib Monotherapy, Tofacitinib with Methotrexate, and Adalimumab with Methotrexate in Patients with Rheumatoid Arthritis (ORAL Strategy): A Phase 3b/4, Double-Blind, Head-To-Head, Randomised Controlled Trial

Fleischmann R, Mysler E, Hall S, Kivitz A, Moots R, Luo Z, DeMasi R, Soma K, Zhang R, Takiya L, Tatulych S, Mojcik C, Krishnaswami S, Menon S, Smolen J, on behalf of the ORAL Strategy investigators.

In this first head-to-head non-inferiority trial assessing a JAKi ± MTX directly compared with a TNFi + MTX in patients with RA, tofacitinib (TOF) + MTX showed non-inferiority to adalimumab (ADA) + MTX. Non-inferiority was not shown for TOF monotherapy versus TOF + MTX, or versus ADA + MTX. In this 52-week study, MTX-inadequate responder (IR) patients were randomised 1:1:1 to receive TOF 5 mg BID monotherapy, TOF 5 mg BID + MTX or ADA 40 mg every other week + MTX. The primary endpoint, A...

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...

The effect of tofacitinib on pneumococcal and influenza vaccine responses in rheumatoid arthritis

Winthrop KL, Silverfield J, Racewicz A, Neal J, Lee EB, Hrycaj P, Gomez-Reino J, Soma K, Mebus C, Wilkinson B, Hodge J, Fan H, Wang T, Bingham CO 3rd.
Ann Rheum Dis. 2015 Mar 20. pii: annrheumdis-2014-207191. doi: 10.1136/annrheumdis-2014-207191. [Epub ahead of print]

The increased risk of serious infection among RA patients means vaccinations against pneumococcus and influenza are recommended in this group of patients. Studies evaluating immune response to these vaccines in conjunction with DMARD therapy can provide clinicians with important information relating to things such as timing of vaccination. This study aimed to assess the effect of tofacitinib on vaccine responses to PPSV-23 and the trivalent seasonal influenza vaccine in those whom tofacitinib...

The JAK inhibitor tofacitinib suppresses synovial JAK1-STAT signalling in rheumatoid arthritis

Boyle DL, Soma K, Hodge J, Kavanaugh A, Mandel D, Mease P, Shurmur R, Singhal AK, Wei N, Rosengren S, Kaplan I, Krishnaswami S, Luo Z, Bradley J, Firestein GS.
Ann Rheum Dis. 2014 Nov 14. pii: annrheumdis-2014-206028. doi: 10.1136/annrheumdis-2014-206028. [Epub ahead of print]

Targeting intracellular pathways such as JAK/STAT represents a novel approach to the treatment of RA. Tofacitinib is an oral JAK inhibitor, proven to be effective in the treatment of RA, yet the pathways affected by tofacitinib and the effects on gene expression in situ are unknown. In this study, Boyle et al. tested the hypothesis that tofacitinib targets cytokine signalling critical to the pathogenesis of rheumatoid synovitis by investigating tofacitinib effects on synovial pathobiology. A...
