Comparison of Baricitinib, Upadacitinib, and Tofacitinib Mediated Regulation of Cytokine Signalling in Human Leukocyte Subpopulations
Arthritis Res Ther. 2019 Aug 2;21(1):183
Different JAKinibs modulated distinct cytokine pathways to varying degrees, and no agent potently or continuously inhibited an individual cytokine signalling pathway throughout the dosing interval. This study aimed to compare the in vitro cellular pharmacology of BARI, TOF and UPA across relevant leukocyte subpopulations, coupled with their in vivo PK, to determine their effects on distinct cytokine pathways. Peripheral blood mononuclear cells from healthy donors were incubated with different JA...

Characterization and Changes of Lymphocyte Subsets in Baricitinib-Treated Patients With Rheumatoid Arthritis: An Integrated Analysis.
Arthritis Rheumatol. 2018 Dec;70(12):1923-1932. doi: 10.1002/art.40680
This review shows that changes in lymphocyte subsets were largely within normal reference ranges and were not associated with efficacy or safety end points. BARI is a selective JAK1/JAK2 inhibitor, approved for the treatment of moderate to severe RA. BARI treatment is associated with changes to circulating lymphocyte and lymphocyte subsets, however detailed analyses of these effects, and their relevance to efficacy and safety is lacking. This study investigated the changes in lymphocyte cell sub...

Lipid Profile and Effect of Statin Treatment in Pooled Phase II and Phase III Baricitinib Studies
Ann Rheum Dis. 2018 Jul;77(7):988-995. DOI 10.1136/annrheumdis-2017-212461
Baricitinib (BARI) was associated with increased lipid levels; baseline statins did not alter these profiles. The introduction of statins during treatment reduced total cholesterol and LDL-C.The use of anti-inflammatory drugs in RA patients has been shown to alter lipid levels and is associated with reduced atherogenic risk. Increases in lipid levels, specifically HDL-C and LDL-C, have been observed in Phase 2 BARI studies1.This study analysed data from seven randomised RA Phase 2/3 studies of ...

Response to Baricitinib based on Prior Biologic Use in Patients with Refractory Arthritis
Rheumatology (Oxford) 2018 May; 57(5):900-908
Baricitinib (BARI) 2 or 4 mg had a beneficial treatment effect on patients with moderate to severe RA compared with placebo (PBO), irrespective of the number or nature of prior patient bDMARD use. The current therapeutic target for patients with established RA is low disease activity, but many patients fail to achieve this due to inadequate responses to DMARD therapies. With this patient population growing, therapies for these patients are considered one of the greatest unmet needs in RA. This s...

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...
