A Phase IIb Study of ABT-494, a Selective JAK-1 Inhibitor, in Patients With Rheumatoid Arthritis and an Inadequate Response to Anti–Tumor Necrosis Factor Therapy

Arthritis Rheumatol 2016;68:2867–77

The summary and accompanying slide deck have been developed in conjunction with the Genovese et al. study (Study 1) which examined ABT-494 in MTX-IR patients in order to compare and contrast the data. In these two Phase 2b studies, ABT-494 (a novel selective JAK-1 inhibitor) was shown to be effective in patients with active RA who were non-responders to MTX or at least one TNF inhibitor.Patients with active RA who had an inadequate response to MTX (study 1) or were refractory to or intolerant of...

The summary and accompanying slide deck have been developed in conjunction with the Kremer et al. study (Study 2) which examined ABT-494 in TNF-IR patients in order to compare and contrast the data. In these two Phase 2b studies, ABT-494 (a novel selective JAK-1 inhibitor) was shown to be effective in patients with active RA who were non-responders to MTX or at least one TNF inhibitor.Patients with active RA who had an inadequate response to MTX (study 1) or were refractory to or intolerant of p...

Effects of Baricitinib on Lipid, Apolipoprotein, and Lipoprotein Particle Profiles in a Phase 2b Study in Patients with Active Rheumatoid Arthritis

Arthritis Rheumatol 2017. DOI 10.1002/art.40036.

In this analysis of the effect of baricitinib on changes in lipid profile, lipoprotein particle size and apolipoprotein content, increases in serum lipids were observed with HDL-C increases correlating with improved clinical outcomes.Eligible patients (N=301) met the inclusion criteria for the Phase 2b randomised, double-blind, placebo-controlled study.1 Patients were assigned in a 2:1:1:1:1 ratio to once-daily doses of placebo or baricitinib 1, 2, 4, or 8 mg, respectively. Those receiving 2 mg,...

fficacy and safety of guselkumab, an anti-interleukin-23 monoclonal antibody, compared with adalimumab for the continuous treatment of patients with moderate to severe psoriasis: Results from the Phase III, double-blinded, placebo- and active comparator-controlled VOYAGE 1 trial

J Am Acad Dermatol 2017;76:405–17. doi: 10.1016/j.jaad.2016.11.041

Guselkumab demonstrated superiority to adalimumab and placebo in treating PsO in this Phase 3 study. Improvements in IGA and PASI scores were observed as early as Week 16 and were maintained up to Week 48. Incidence of adverse events was similar across both treatment groups.

Efficacy and safety of guselkumab, an anti-interleukin-23 monoclonal antibody, compared with adalimumab for the treatment of patients with moderate to severe psoriasis with randomized withdrawal and retreatment: results from the Phase III, double-blind, placebo- and active comparator-controlled VOYAGE 2 trial

J Am Acad Dermatol 2017;76:418–31. doi: 10.1016/j.jaad.2016.11.042

Patients treated with guselkumab showed an improved and sustained clinical response compared to both adalimumab and placebo, without compromising safety profile. The Phase 3 VOYAGE 2 trial by Reich et al focused on treatment interruption and withdrawal, as well as treatment switching from adalimumab to guselkumab.

Biologic or Tofacitinib Monotherapy for Rheumatoid Arthritis in People with Traditional Disease-modifying Anti-rheumatic Drug (DMARD) Failure: a Cochrane Systematic Review and Network meta-analysis (NMA)

Cochrane Database Syst Rev 2016;11:CD012437.

Treatment options for RA patients who are MTX/DMARD incomplete responders (IR) include other DMARDs, biologics or tofacitinib (TOF). However, there is a lack of direct head-to-head comparator trials of biologics in people with RA. This review provides an update of the 2009 Cochrane overview, ‘Biologics for rheumatoid arthritis’,1 and provides comparisons and estimates for biologic or TOF monotherapy in MTX/DMARD-IR people with RA.The benefits and harms of biologic monotherapy (TNFis: adalimumab,...

Pregnancy Outcomes in the Tofacitinib Safety Databases for Rheumatoid Arthritis and Psoriasis

Drug Saf. 2016 June 9; 39:755–762; DOI 10.1007/s40264-016-0431-z [Epub ahead of print]

RA and psoriasis may present in women of child-bearing potential, however there are currently no adequate or well-controlled studies of tofacitinib (TOF) or any DMARD in pregnant women. Pregnancy was an exclusion criterion of TOF randomized clinical trials because of the unknown effects of TOF on mother and child; TOF is a small molecule with the potential to cross the placenta. The current analysis looked at reported pregnancies and their outcomes from TOF RA and psoriasis clinical safety datab...

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...

Efficacy and safety of the oral Janus kinase inhibitor peficitinib (ASP015K) monotherapy in patients with moderate to severe rheumatoid arthritis in Japan:a 12-week, randomised, double-blind, placebo-controlled phase IIb study

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...

Biologics or Tofacitinib for Rheumatoid Arthritis in Incomplete Responders to Methotrexate or Other Traditional Disease-Modifying Anti-Rheumatic Drugs: A Systematic Review and Network Meta-Analysis

Cochrane Database of Systematic Reviews 2016 Issue 5. Art. No.: CD012183 [DOI: 10.1002/14651858.CD012183].

Treatment options for RA patients who are MTX/DMARD incomplete responders (IR) include other DMARDs, biologics or tofacitinib (TOF). However, there is a lack of head-to-head studies to show any important differences between these options in terms of benefits and harms. This review provides an update of the 2009 Cochrane overview and network meta-analysis (NMA) of biologics for RA.1Nine biologics (abatacept, adalimumab, anakinra, certolizumab pegol, etanercept, golimumab, infliximab, rituximab, a...
