関節リウマチ患者におけるトファシチニブのリンパ球に対する短期、中期、長期的影響

Arthritis Rheumatol 2018 DOI: 10. 1002/art.40780

Tofacitinib (TOF) treatment is associated with short-term transient increases in absolute lymphocyte counts (ALC), followed by a gradual decline to reach steady state by ~48 months. Changes in both ALC and lymphocyte subset counts (LSC) were reversible upon TOF discontinuation. Low ALC but not LSC were associated with an increased risk of serious infective episodes (SIEs) and herpes zoster (HZ). This data supported the treatment recommendations on ALC counts for starting and continuing therapy w...

トファシチニブ使用時の帯状疱疹は、グルココルチコイド併用でさらに増加するが、メソトレキセートでは増加しない

Arthritis Care Res 2018 DOI 10.1002/acr.23769

The rate of Herpes Zoster (HZ) in tofacitinib (TOF) users with concomitant glucocorticoids (GC) was approximately double that of other TOF combination therapies.TOF is an effective treatment for RA. Increased HZ risk has been observed with the use of JAK inhibitors, whereas the HZ risk with biologics and targeted RA therapies are comparable. This study evaluated the HZ risk in TOF users according to concomitant GC, MTX, both, or neither. MarketScan and Medicare data were used to identify 8030 rh...

疾患が持続的にコントロールされた関節リウマチ患者におけるバリシチニブ減量: プロスペクティブコホート

Ann Rheum Dis. 2019 Feb;78(2):171-178. DOI 10.1136/annrheumdis-2018-213271

In active RA patients, with an inadequate response (IR) to DMARDs who achieve low disease activity (LDA) following baricitinib (BARI) 4 mg treatment, disease control is better maintained with continued BARI 4 mg compared to tapering to 2 mg.The objective of this study was to investigate the effect of BARI tapering in patients achieving sustained disease control with BARI 4 mg.In the long-term extension study RA-BEYOND, patients receiving BARI 4 mg who achieved sustained LDA or remission at two c...

活動性関節リウマチ患者におけるバリシチニブの中央値2年間の安全性

J Rheumatol. 2019 Jan;46(1):7-18. DOI: 10.3899/jrheum.171361

Baricitinib (BARI) showed an acceptable 5.5-year safety profile in this integrated analysis of patients with moderate-to-severe, active RA.This study evaluated the safety profile of the oral, once daily Janus kinase inhibitor, BARI, in adults with moderately to severely active RA. Data from eight randomised clinical trials and one long-term extension study were pooled and analysed for placebo comparison and dose response.There were 3492 patients who received BARI for a total of 6637 patient-yea...

JAK阻害薬治療中関節リウマチ患者の有害事象，臨床的配慮 およびマネージメント

Exp Rev Clin Immunol 2018 Nov;14(11):945-956. DOI: 10.1080/1744666X.2018.1504678

Janus kinase (JAK) inhibitors are efficacious in patients with moderate-to-severe RA and have a favourable safety profile. However adverse events (AE), in particular infections, are associated with the use of JAK inhibitors. This paper reviews the mechanism behind JAK inhibitors, the AEs associated with them, and provides consideration in the management of AEs in clinical practice. Data on two RA approved JAK inhibitors – tofacitinib (TOF) and baricitinib (BARI) – was obtained using PubMed, Medl...

従来型抗リウマチ薬に効果不十分な関節リウマチ患者におけるウパダシチニブの安全性と有効性 (SELECT-NEXT): 無作為化二重盲検プラセボ対照フェーズ3治験

Lancet 2018;391:2503–12

Patients with moderate-to-severe active RA had significant improvements in clinical signs and symptoms with upadacitinib (UPA) compared with placebo.In Phase 2 studies, UPA showed favourable efficacy when administered twice daily as an immediate-release formulation at doses of 6–12 mg in patients with active RA who had TNFi-IR.1,2 An extended-release formulation allowing once-daily (QD) administration was developed for Phase 3 studies. SELECT-NEXT was a double-blind, multicentre, Phase 3 study t...

患者特徴は関節リウマチにおける生物学的製剤選択に影響し, non-TNFi をTNFiよりも有害に見せてしまう

Ann Rheum Dis 2018; 77:650–57 DOI: 10.1136/annrheumdis-2017-212395

Analysis of patient characteristics revealed that older and less healthy patients with RA were more likely to receive non-TNFi bDMARDs as a first bDMARD compared to other treatments.This study aimed to describe patient characteristics at initiation of bDMARD treatment at two-time points: first bDMARD initiation and switch to second bDMARD after TNFi treatment. The second aim of the study was to estimate the potential of treatment channelling to confound results in comparative treatment studies i...

関節リウマチにおけるトファシチニブの効果と安全性: コホート研究

Arthritis Res Ther 2018; 20(1):60 doi: 10.1186/s13075-018-1539-6

A retrospective cohort study of tofacitinib (TOF) revealed that patients previously treated with methotrexate who initiated TOF, presented no differences in hospitalised infections or effectiveness, compared with non-TNF biologics. Currently, TOF is recommended in ACR and EULAR guidelines as an alternative to biologics after first-line cDMARD therapy. Previous indirect comparisons have shown that patients with RA who experience cDMARD failure show similar efficacy when given TNFis, abatacept, to...
