Metotreksata yetersiz yanıt veren romatoid artritli hastalarda baricitinibin 24 haftadaki güvenlik ve etkinliği

Ann Rheum Dis. 2015;74(2):333–340

Recent innovations in the treatment of RA have focused on the use of small molecules to inhibit intracellular kinases such as the JAK family. Baricitinib (LY3009104, formerly INCB028050) is an orally administered, potent, selective and reversible inhibitor of JAK1 and JAK2, which has shown anti-inflammatory effects, as well as preservation of cartilage and bone, in preclinical rodent studies.

This phase IIb study was designed to investigate multiple doses and dosing regimens of baricitin...

JAK inhibitörü tofacitinib romatoid artritte sinovyal JAK1-STAT sinyalizasyonunu baskılar

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.

Randomize klinik çalışmalarda biyolojik ilaçlar ve tofacitinib ile tedavi edilen kronik inflamatuar artritli hastalardaki lipid profili değişiklikleri: Bir sistematik derleme ve meta analiz

Arthritis Rheumatol. 2015;67(1):117–127

Systemic inflammation, reflected by high levels of C-reactive protein and the erythrocyte sedimentation rate, has been identified as an independent risk factor for cardiovascular disease, the most important cause of death in RA and SpA. Studies with TNF antagonists have given contradictory results on cardiovascular risk. As such, this systemic literature search aimed to analyse lipid changes in RA and SpA subjects treated with biologics or tofacitinib in randomized clinical trials.

The s...

The risk of cardiovascular (CV) disease among RA patients, compared with the general population is well documented. Alongside this, studies have been able to establish that risk factors in RA patients are not wholly associated with traditional CV risk factors such as such as diabetes mellitus, hypertension, smoking, and dyslipidemia, suggesting a relationship between parameters of RA disease activity and increased CV risk. Additionally, IL-6 has been linked with the development of coronary heart...

Tofacitinib ile tedavi edilen aktif romatoid artritli hastalarda serum kreatinin düzeylerinde değişiklikler: klinik çalışmalardan elde edilen sonuçlar

Arthritis Res Ther. 2014;16(4):R158

Despite preclinical and healthy volunteer studies of tofacitinib showing no evidence of nephrotoxicity, increases in mean serum creatinine levels have been observed in patients treated with the drug during the RA clinical development programme. This report explores the clinical significance of this change.

Serum creatinine values and renal adverse event data were pooled from patients who received =1 dose of tofacitinib either with background DMARDs or as monotherapy in five Phase 3 studie...

Romatoid Artritli Hastalarda Tofacitinib’in Faz II, III ve Uzun-Dönem Uzatma Çalışmalarında Enfeksiyonun ve Tüm-Nedenlere-Bağlı Mortalitenin Analizi

Arthritis Rheumatol. 2014;66(11):2924–2937

This study pools data from the global tofacitinib RA development programme (phase II, phase III and long-term extension studies) to determine the rate of infections and all-cause mortality with tofacitinib treatment. In total, 4,789 patients within these studies received tofacitinib, at varying doses and with varying duration.

The overall incidence rate of serious infections was 3.09 events/100 patient-years (95% CI 2.73–3.49), which was stable over time, with pneumonia and skin and soft...

Romatoid Artrit Hastalarında Tofacitinib ve Herpes Zoster

Arthritis Rheumatol. 2014 Jun 18. [Epub ahead of print]

It is well established that patients with RA are at an increased risk of herpes zoster (HZ). What is less well known is whether some of the newer therapies available for treatment of RA increase this risk. Tofacitinib has been reported to be associated with an increased risk of HZ and this study quantifies that risk and reviews potential factors that represent an increased risk. Using data from the tofacitinib RA development programme; phase 2, 3, and long-term extension clinical trials, over 20...

ORAL Start is the latest trial to be reported in the tofacitinib clinical development programme. It compares the use of tofacitinib monotherapy to MTX monotherapy, in RA patients who have had either no or a sub-therapeutic dose of MTX in the past. Nine hundred and fifty eight patients received either tofacitinib (5 mg or 10 mg) twice daily, or methotrexate at a dose that was incrementally increased to 20 mg per week over 8 weeks. The co primary efficacy endpoints were ACR 70 response, and mean c...

This study pooled data from two LTE studies involving patients who had previously participated in qualifying phase I, II and III studies. Data up to 60 months was included for safety aspects and efficacy data up to 48 months. However data for 10 mg BID and tofacitinib monotherapy was limited after 24 and 36 months respectively. Over the two studies, 4102 patients were treated for a total of 5963 patient years.Herpes zoster, both serious and non-serious, had a higher incidence rate in tofacitinib...

Systematic literature reviews were undertaken to assess the efficacy of csDMARDs, glucocorticoids and tofacitinib in the treatment of RA. The first two were updates to reviews conducted for the 2010 recommendations while the tofacitinib SLR was a complete review.Two studies identified by the csDMARD SLR, tREACH and TEAR, compared efficacy between MTX mono- and combination therapy (MTX+SSZ+HQ). Both of these studies found there was no benefit to immediate triple therapy.Further studies analysing ...
