体軸関節炎患者にいつセクキヌマブを使うか: 抗TNFα 治療前それとも後?

Reumatol Clin. 19 (2023); 175–179 doi 10.1016/j.reumae.2022.03.007

Secukinumab, an IL-17A monoclonal antibody, was shown to have remarkable efficacy for axSpA in the MEASURE 2 and MEASURE 3 trials. Previous studies have concluded that secukinumab was more efficacious in TNFi-naïve patients.

Tocilizumab as Monotherapy or Combination Therapy for Treating Active Rheumatoid Arthritis: a Meta-analysis of efficacy and Safety Reported in Randomized Controlled Trials

Arthritis Res Ther 2016; 18:211. DOI 10.1186/s13075-016-1108-9

This is the first meta-analysis comparing efficacy and safety of TCZ monotherapy (TCZMONO) versus TCZ + csDMARD (TCZCOMBI) in patients with RA. The findings show that similar efficacy can be expected with TCZ monotherapy in patients with intolerance to csDMARDs compared with inadequate responders to csDMARDs who switch to TCZ add-on therapy.A total of 6679 patients from 13 studies were included, receiving: 1298, TCZMONO; 3077, TCZCOMBI; 2204, csDMARDs. Meta-analyses were performed for the follow...

Combined inhibition of TNFα and IL-17 as therapeutic opportunity for treatment in rheumatoid arthritis: Development and characterization of a novel bispecific antibody

Arthritis Rheumatol. 2015;67(1):51–62

Single cytokine inhibition, e.g. TNFα or IL-6, has fundamentally improved the therapeutic armamentarium for the treatment of RA; yet clinically meaningful responses are achieved in only about half of RA patients treated. In addition, it is now well established that the pathogenesis of RA involves multiple mechanisms of cell activation and cell recruitment. These two factors have led to the emergence of the concept of dual specificity, sparking interest in the biologic arena, with a focus o...

The active metabolite of spleen tyrosine kinase inhibitor fostamatinib abrogates the CD4+T cell-priming capacity of dendritic cells

Rheumatology (Oxford). 2015;54(1):169–177

SYK is a core signalling protein that drives inflammatory responses and is fundamental to the propagation of signals via numerous immune receptors. While the clinical development of the first SYK inhibitor, fostamatinib, was stopped due to poor results in the phase 3 RA programme, there remain important questions of mechanism which may aid future developments of this target.

In these murine studies, investigators sought to gain an understanding of how the active metabolite of fostamatini...

Selective inhibition of spleen tyrosine kinase (SYK) with a novel orally bioavailable small molecule inhibitor, RO9021, impinges on various innate and adaptive immune responses: implication for SYK inhibitors in autoimmune disease therapy

Arthritis Research and Therapy 2013 15:R146

Spleen tyrosine kinase (SYK) has already been described as a potential therapeutic target for the treatment of autoimmune diseases. Previously the SYK inhibitor fostamatinib was in clinical development for the treatment of rheumatoid arthritis, but has since been suspended. However, investigation into SYK inhibition continues with RO2091, a novel ATP-competitive inhibitor of SYK with reasonable selectivity, potency and oral bioavailability which has been shown to suppress various innate and adap...

The JAK inhibitor tofacitinib for active rheumatoid arthritis: results from phase III trials

International Journal of Clinical Rheumatology June 2013; 8(3):311–13

The tofacitinib ORAL research program involves six phase 3 trials (Standard, Solo, Step, Scan, Sync and Start) to assess the safety and efficacy of tofacitinib 5 and 10 mg twice daily as monotherapy, or with either background MTX or traditional DMARD therapy. This report by Salgado et al. provides an overall analysis of the each of the study designs and the clinical results to date. The results show that tofacitinib effectively controlled the signs and symptoms of RA across a range of patient po...
