TNF Inhibitörlerine Yetersiz Yanıtlı Aktif Romatoid Artrit Hastalarında Tofasitinib ve Biyolojik Tedavilerin Karşılaştırılması: Bir Network Meta Analizinin Sonuçları

Clin Ther 2016;38:2628–40.

This network meta-analysis, performed within a Bayesian framework, concluded that tofacitinib 5 mg BID has efficacy and AE rates comparable with currently available bDMARDs over a 24-week period in patients experiencing an inadequate response to TNF therapy. A systematic literature search identified five, Phase 2 or beyond, randomised controlled trials for inclusion in the analysis. Each trial had an adult population with moderate to severe RA, with inadequate response (IR) or failed treatment w...

Orta ve ciddi Romatoid Artritte oral Janus Kinaz inhibitörü peficitinib'in (ASP015K) monoterapi olarak ekinlik ve güvenliği, Japonya verisi: 12 haftalık, randomize, çift-kör, plasebo-kontrollü faz llb çalışma

Ann Rheum Dis. 2016 Jun;75:1057-64. doi: 10.1136/annrheumdis-2015-208279. Epub 2015 Dec 15

Peficitinib (ASP015K) is a novel orally bioavailable JAK inhibitor in development for the treatment of RA. It inhibits JAK1, JAK2, JAK3 and Tyk2 enzyme activities and has moderate selectivity or JAK3 inhibition.Here the authors report the findings of a 12-week, randomized, double-blind, placebo-controlled phase IIb study evaluating efficacy, safety and dose response of peficitinib (25, 50, 100, or 150 mg) as once-daily oral monotherapy in Japanese patients with moderate to severe RA. The primar...

Romatoid Artrit Hastalarında Tofasitinib, Tocilizumab veya Diğer Biyolojik Tedavilerin Gastrointestinal Perforasyon Riskleri

Arthritis Rheumatol. 2016 May 17. DOI 10.1002/art.39761 [Epub ahead of print]

Historically, patients with RA have suffered with upper tract gastrointestinal perforation (GIPs), associated with NSAID use. More recently, the IL-6 receptor antagonist tocilizumab (TCZ) has been associated with lower tract GIPs. Janus kinase (JAK) inhibitors, including tofacitinib (TOF), with some downstream effects on IL-6 signalling, also have potential for an increased risk of GIPs.There is limited real-world evidence and almost no comparative evidence on the risk for GIP associated with TC...

Aktif Psoriatik Artritli Erişkin Hastaların Faz 2b Çalışmasında Anti-İnterlökin-6 Monoklonal Antikoru Clazakizumab'ın Etkinliği ve Güvenliği

Arthritis Rheumatol. 2016 Mar 24. DOI 10.1002/art.39700 [Epub ahead of print]

Encouraging results have been seen with clazakizumab in RA, but the results of anti-IL6 therapy in patients with psoriatic arthritis (PsA) have so far been unclear. This Phase 2b dose-ranging study examined the efficacy and safety of clazakizumab given subcutaneously q4w, with or without MTX, in 165 patients with PsA who had inadequate response to NSAIDs.ACR20 response at Week 16, the primary endpoint, was significantly higher in patients receiving clazakizumab 100 mg compared with placebo (52.4...

Tofasitinibin günde bir kez kullanılan uzatılmış salınımlı formulasyonu: çabuk salınımlı tofasitinib ile farmakokinetik karşılaştırılması ve yemek etkisinin değerlendirilmesi

J Clin Pharmacol. 2016 Mar 11. doi: 10.1002/jcph.734. [Epub ahead of print]

PK profile of TOF is rapid absorption and elimination with time to max concentration 0.5-1 hour and terminal half-life at 3 hours. It is currently approved for immediate release (IR) 5 mg BID, 10 mg total; however, decreasing the dosage to QD dosing may help increase compliance. This study performed in 24 healthy males compared the PK of XR and IR TOF under both single and multiple dose conditions and evaluated the effect of a high-fat meal on the PK of XR TOF. There were no clinically important...

Metotreksata yetersiz yanıtlı romatoid artritli hastalarında metotreksata tosilizumab eklenmesi yada tosilizumab tedavisine geçiş tedavilerinin karşılaştırılması: 52 haftalık prospektif, randomize kontrollü çalışma (SURPRISE çalışması)

Ann Rheum Dis 2016 Jan 5 DOI: 10.1136/annrheumdis-2015-208426 [Epub ahead of print

MTX is the primary drug in RA management because of its long-term effectiveness and safety profile; however, in patients who have insufficient response (IR) to MTX, treatment adjustments are needed – either to combine a bDMARD with MTX or to switch to a bDMARD from MTX. In the SURPRISE study, the efficacy and safety of adding TCZ to MTX (ADD-ON) or switching MTX to TCZ (SWITCH) was evaluated in 233 patients with moderate to highly active RA who were randomised 1:1. Both treatment groups were adm...

Romatoid Artritde Sitokinler– İmmnünolojik Manzara

Nat Rev Rheumatol. 2016 Jan;12(1):63-8

Cytokine-mediated pathways are central to the pathogenesis of rheumatoid arthritis and there has been great advances in understanding and clinical application in the last 20 years. McInnes and colleagues provide a timely and succinct overview the roles of cytokine families in the various phases and tissue compartments of this disease. They particularly review the combinatorial role played by cytokines in mediating the overlapping innate and adaptive immune responses associated with disease onset...
