Safety and Efficacy of Baricitinib through 128 Weeks in an Open-label, Longterm Extension Study in Patients with Rheumatoid Arthritis

J Rheumatol. 2018 Jan;45(1):14-21. doi: 10.3899/jrheum.161161

This open-label extension (OLE) of a Phase 2b randomised controlled trial (RCT) found that safety data collected over 2 years of treatment were generally consistent with previous findings for baricitinib in RA.In the RCT, baricitinib demonstrated significant improvement in disease activity compared with placebo and an acceptable safety profile in patients with RA and an inadequate response to MTX. Patients who completed the 24-week double-blind period of the study were eligible for the OLE. Rate...

Filgotinib (GLPG0634/GS-6034), an oral selective JAK1 inhibitor, is effective as monotherapy in patients with active rheumatoid arthritis: results from a randomised, dose-finding study (DARWIN 2)

Ann Rheum Dis 2017;76:1009–19

In these two Phase 2b studies, filgotinib (a selective JAK-1 inhibitor) was shown to improve the signs and symptoms of RA (compared with placebo), either as monotherapy or when added to MTX.DARWIN 1 included 594 patients with moderate to severe RA on a stable dose of MTX, while DARWIN 2 included 283 patients who stopped taking MTX before the start of the study. After 12 weeks’ treatment, significantly more patients who were receiving filgotinib 100 mg or 200 mg daily in DARWIN 1 or any filgotini...

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...

Arthritis Rheumatol 2016;68:2857–66

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...

Peficitinib, a JAK Inhibitor, in Combination with Limited Conventional Synthetic DMARDs in the Treatment of Moderate-to-severe Rheumatoid Arthritis

Arthritis Rheumatol DOI 10.1002/art.40054. Accepted article.

In this Phase 2b study in patients with moderate to severe RA, once-daily peficitinib in combination with limited csDMARDs reduced the symptoms of RA, demonstrated adose-dependent ACR20 response rate over 12 weeks, and showed acceptable tolerability. This 12-week study included patients who had an inadequate response or intolerance to csDMARDs (N=289). Patients were randomised 1:1:1:1:1 to peficitinib 25-, 50-, 100, 150 mg or matching placebo. Statistically significant differences in the ACR20 r...

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,...
