Systematic review and meta-analysis of serious infections with tofacitinib and biologic disease-modifying antirheumatic drug treatment in rheumatoid arthritis clinical trials

Arthritis Res Ther. 2015 Dec 15;17(1):362

Tofacitinib is an oral Janus kinase inhibitor for the treatment of RA. By modulating the signalling of cytokines that are integral to lymphocyte activation, proliferation, and function, tofacitinib may suppress multiple elements of immune response. A systematic literature search including all biologics and tofacitinib procured 66 RCTs and 22 LTEs that were included in a meta-analysis to provide estimated incidence rates, risk ratios, and risk differences of serious infection for each therapy. Es...

Comparison of lipid and lipid-associated cardiovascular risk marker changes after treatment with tocilizumab or adalimumab in patients with rheumatoid arthritis

Ann Rheum Dis. 2015;0:1-7. doi:10.1136/annrheumdis-2015-207872 [Epub ahead of print]

RA patients have increased risk of CVD compared with the general population that is not fully explained by traditional risk factors. This is a post-hoc analysis of data from a clinical trial that compared IL-6 and TNF-α signaling inhibition to compare changes in lipids and lipid-associated CV risk markers in 324 patients treated with TCZ IV q4w or ADA SC q2w for 24 weeks. HDL-SAA and sPLA2 IIA is also measured in an additional subpopulation of 87 and 97 TCZ and ADA patients, respectively.Greater...

Incidence and complications of interstitial lung disease in users of tocilizumab, rituximab, abatacept and anti-tumor necrosis factor α agents, a retrospective cohort study

Arthritis Research & Therapy (2015) 17:319 DOI: 10.1186/s13075-015-0835-7

Interstitial lung disease (ILD) is a common extra-articular condition for RA patients. This retrospective cohort study of health insurance databases investigates the ILD incidence and exacerbation between ABA, TCZ, RTX, and anti-TNFα agents in adult RA patients with prior biologic therapy. Two definitions of ILD were used: one specific, one sensitive; descriptive results were produced for both. In patients with no history of ILD, the overall incidence rate of ILD ranged from 1.8% to 6.4% (depend...

Efficacy and safety of olokizumab in Asian patients with moderate-to-severe rheumatoid arthritis, previously exposed to anti-TNF therapy: Results from a randomized phase II trial

Modern Rheumatology. 2015 Sep 10:1-9. [Epub ahead of print]

This Phase II study assessed the safety and efficacy of olokizumab in Asian patients with moderate-to-severe rheumatoid arthritis, previously exposed to anti-TNF therapy. After 12 weeks of treatment, olokizumab was found to rapidly improve disease activity in patients who had previously failed anti-TNF therapy. There was also a significant decrease in ACR20 and ACR50 responder rates at week 12. The safety findings were consistent with the safety profile expected for this drug class. These findin...

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

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 more ...

Efficacy and safety of tofacitinib as monotherapy in Japanese patients with active rheumatoid arthritis: a 12-week, randomized, phase 2 study

Modern Rheumatology. 2015 Jul;25(4):514-21. doi: 10.3109/14397595.2014.995875.

The oral Janus kinase (JAK) inhibitor, Tofacitinib, preferentially inhibits signalling by heterodimeric receptors associated with JAK3 and/or JAK1, blocking signalling for several cytokines. The purpose of this study was to evaluate the efficacy of tofacitinib monotherapy versus placebo in Japanese patients with inadequate response to disease-modifying anti-rheumatic drugs (DMARDs). Data on response rates – ACR20/50/70, DAS28-4(ESR), and HAQ-DI – laboratory parameters and adverse events were col...

The Efficacy and Safety of Subcutaneous Clazakizumab in Patients with Moderate-to-Severe Rheumatoid Arthritis and Inadequate Response to Methotrexate: Results from a Phase IIb, Randomized, Double-Blind, Placebo/Active-Controlled, Dose-Ranging, Multinational Study

Arthritis & Rheumatology. 2015 Jul 2. doi: 10.1002/art.39249. [Epub ahead of print]

The humanised monoclonal antibody, Clazakizumab (CLZ), binds to circulating interleukin-6 (IL-6) cytokine rather than the IL-6 receptor, blocking both classical and trans-signalling. The purpose of this phase 2B study was to evaluate the efficacy and safety of clazakizumab in patients with inadequate response to methotrexate (MTX). Data on selected response rates – ACR20/50/70, DAS28-CRP, SDAI ≤3.3, CDAI ≤2.8 and the ACR/EULAR Boolean definition – and adverse events were collected from 418 patie...

Long-term Safety of Tocilizumab: Results from 3 Years of Followup Postmarketing Surveillance of 5573 Patients with Rheumatoid Arthritis in Japan

The Journal of Rheumatology. 1 June 2015 DOI: 10.3899/jrheum.141210 [Epub ahead of print]

The humanised anti-interleukin 6 receptor monoclonal antibody tocilizumab (TCZ) has been available in clinical practice for several years. The purpose of this study was to evaluate the long-term safety of for the treatment of RA in a real-world clinical setting as a long-term extension of a single-arm, observational post marketing surveillance study. Data on selected adverse events (AEs) - fatal events, serious infection, malignancy, GI perforation, and serious cardiac dysfunction - were collect...

Tofacitinib, an oral Janus kinase inhibitor, for the treatment of chronic plaque psoriasis: results from two, randomised, placebo-controlled, Phase 3 trials

British Journal of Dermatology. 7 July 2015 DOI: 10.1111/bjd.14018. [Epub ahead of print]

The management of moderate to severe chronic plaque psoriasis has benefited from the introduction of biological therapies, but unmet needs still remain, especially for oral therapies. Tofacitinib is an orally active agent that blocks signalling of key cytokines implicated in the immune response and inflammatory pathways of psoriasis. The Phase III studies presented in this paper analysed efficacy and safety endpoints.Both studies demonstrated that tofacitinib in both 5 mg and 10 mg twice daily d...

Efficacy and safety of subcutaneous tocilizumab versus intravenous tocilizumab in combination with traditional DMARDs in patients with RA at week 97 (SUMMACTA)

Ann Rheum Dis. 10 May 2015 doi:10.1136/annrheumdis-2015-207281 [Epub ahead of print]

Tocilizumab (TCZ) has demonstrated efficacy and a well-established safety profile for intravenous (IV) administration. The Phase III SUMMACTA study evaluated the efficacy and safety of subcutaneous tocilizumab (TCZ-SC) in combination with DMARDS in patients with moderate-to-severe RA and inadequate response to ≥1 DMARD. Patients were randomised to receive TCZ-SC 162 mg weekly or TCZ-IV 8 mg/kg q4w in combination with DMARDs. After a 24-week double-blind period, patients receiving TCZ-SC were re-...
