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...

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,...

Safety and efficacy of baricitinib at 24 weeks in patients with rheumatoid arthritis who have had an inadequate response to methotrexate

Ann Rheum Dis. 2015;74(2):333–340

Recent innovations in the treatment of RA have focused on the use of small molecules to inhibit intracellular kinases such as the JAK family. Baricitinib (LY3009104, formerly INCB028050) is an orally administered, potent, selective and reversible inhibitor of JAK1 and JAK2, which has shown anti-inflammatory effects, as well as preservation of cartilage and bone, in preclinical rodent studies.

This phase IIb study was designed to investigate multiple doses and dosing regimens of baricitin...
