This Phase 2b study of peficitinib (ASP015K), an orally administered once-daily JAK inhibitor, plus MTX, demonstrated efficacy across multiple secondary endpoints with higher peficitinib doses. Peficitinib in combination with MTX was well tolerated with a safety profile that was consistent with previous studies.A high placebo response rate was seen in both Latin and North America, when patient data were stratified. This high placebo rate is problematic for the accurate interpretation of peficit...
This Phase 2b study of VX-509 (decernotinib), a selective JAK3 inhibitor, showed that VX-509 in combination with stable DMARD therapy was effective for improving synovitis and osteitis as assessed by MRI in patients who had an inadequate response to DMARD therapy.Patients were randomised to treatment groups receiving either placebo, VX-509 100 mg, 200 mg or300 mg for 12 weeks. Minimum inclusion criteria included Grade ≥2 clinical synovitis in either the wrist or two metacarpophalangeal joints. A...

In this 52-week study of patients receiving initial therapy for RA, baricitinib alone or in combination with MTX demonstrated superior efficacy compared with MTX alone.Patients naïve to csDMARD (no or <3 doses of MTX) or bDMARD were randomised 4:3:4 (N=588) toMTX QW, baricitinib 4 mg QD or baricitinib 4 mg QD + MTX QW. The primary endpoint assessment was noninferiority of baricitinib monotherapy to MTX based on ACR20 response at Week 24.Not only was the primary endpoint met, baricitinib monother...

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...
Evidence is presented that treatment with sarilumab improves patient-reported outcomes (PROs). These improvements complement the clinical efficacy previously reported for sarilumab.Data were analysed from the 52-week Phase 3 MOBILITY randomised controlled trial in adult patients with active RA and previous inadequate response to MTX. Patients received subcutaneous placebo or sarilumab 150 mg or 200 mg every 2 weeks in combination with MTX, for 52 weeks.PROs assessed were: Patient Global Assessme...

This dose-ranging study evaluated the efficacy of the novel, selective JAK1 inhibitor ABT-494 versus placebo in patients with moderate-to-severe RA and inadequate response (IR) to MTX.In this 12-week, randomised, double-blind study (BALANCE II), the efficacy and safety ofABT-494 dosed at 3mg, 6 mg, 12 mg, 18 mg (all twice daily) and 24 mg (once daily) was assessed. Patients included had not received prior biologic therapy.Of the 299 patients included in the analysis, the proportions of patients ...

Switching from Adalimumab to Tofacitinib in the Treatment of Patients with Rheumatoid Arthritis

Arthritis Research & Therapy. 2016. DOI 10.1186/s13075-016-1049-3 [Epub ahead of print]

Results are reported from an analysis exploring the safety and efficacy of open-label tofacitinib (TOF) following blinded treatment with TOF or adalimumab (ADA) in patients with moderate to severe RA. The analysis included patients from ORAL Sequel, an open-label long-term extension study, which all patients entered following ORAL Standard (one of the studies in the TOF phase 3 program). Only those patients who had been randomized to ADA 40 mg Q2W + MTX or 10 mg TOF + MTX in ORAL Standard were i...
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...

Two-year Efficacy of Tocilizumab in Patients with Active Rheumatoid Arthritis in Clinical Practice

Reumatol Clin. 2016; May 10 doi: 10.1016/j.reuma.2016.03.014 [Epub ahead of print]

The efficacy and safety of tocilizumab has been studied in several randomized clinical trials (RCTs) but due to the strict inclusion and exclusion criteria of RCTs, real-life observational studies are needed to supplement the findings from these trials. This small longitudinal, open-label study from an outpatient clinic in Spain evaluated the effectiveness, survival rate and reasons for treatment discontinuations in 85 patients treated with tocilizumab over a 24-month period. The study also ass...
Clinical trials have shown baricitinib once daily to be effective in patients with RA. However, this Janus kinase (JAK) 1/JAK2 inhibitor has not been evaluated in a Japanese population. In this 12-week, placebo-controlled study, 145 Japanese patients were enrolled and received placebo, 1 mg, 2 mg, 4 mg or 8 mg oral baricitinib daily. Efficacy results were encouraging and consistent with earlier trials. Significantly more baricitinib patients achieved ACR20 response at Week 12 of treatment compar...
