This 24-week update from the baricitinib RA-BEYOND LTE study follows patients previously treated in the pivotal study RA-BEGIN. It demonstrates the maintained safety and efficacy of baricitinib monotherapy, and the effects of concurrent MTX treatment on response rates and patient reported outcomes. Previous P3 study RA-BEGIN demonstrated the superior efficacy of 4mg baricitinib compared to MTX monotherapy up to 52 weeks, with no major safety events being identified. At the end of the trial, pa...

This study aimed to characterize temporary interruptions of baricitinib and describe their impact on efficacy and safety. Brief interruptions during phase 3 baricitinib trials were associated with minor increases in symptoms which were resolved following treatment. In life-long, chronic conditions such as RA, interruption of therapy is common for various reasons, such as side effects, non-compliance, or because a patient requires surgery. Concerns have been raised that these treatment breaks c...

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 s...

Patients with active RA and little or no prior DMARD treatment, who achieved sustained clinical responses, were less likely to show structural damage progression, irrespective of treatment. RA-BEGIN was a 52-week double-blind, multicentre Phase 3 trial, which assessed the safety and efficacy of BARI as monotherapy or in combination with MTX versus MTX monotherapy, in RA patients with no or limited prior DMARDs use.1-4 This post-hoc analysis evaluated the structural damage progression in patients...

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 o...

Once daily baricitinib (BARI) inhibited radiographic progression of structural joint damage in patients with an inadequate response or intolerance to csDMARDs over 48 weeks. Current treatment goals aim to use DMARDs to inhibit structural joint damage and prevent long-term functional disability. In RA-BUILD¹, BARI was shown to significantly reduce radiographic joint damage progression in patients with active RA, with an intolerance or inadequate response to csDMARDs. Here, the authors repor...

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...

Eficacia y Seguridad de Baricitinib en Pacientes Ancianos con Artritis Reumatoide

RMD Open. 2017; 3(2): e000546. doi: 10.1136/rmdopen-2017-000546

In this post hoc analysis of pooled data from two randomised controlled trials, RA-BUILD and RA-BEAM, age was shown not to be a contraindication for use of baricitinib. Patients in RA-BUILD were csDMARD-inadequate responder(IR) patients who received an oral placebo or 2 mg or 4 mg baricitinib once daily. Patients in RA-BEAM were MTX-IR patients and received an oral placebo, 4 mg baricitinib once daily or subcutaneous adalimumab every 2 weeks. Efficacy and safety of baricitinib in elderly patie...

RA-BEGIN was a Phase 3, double-blind randomised active comparator-controlled study to evaluate baricitinib as monotherapy or in combination with MTX in patients with active RA who were naïve to csDMARDS and bDMARDS. In this analysis of the RA-BEGIN study, baricitinib alone or with MTX when used as initial therapy resulted in significant improvements in most patient-reported outcome measures compared with MTX. At baseline, study participants had active RA, impaired physical function, mode...

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. Ra...

Baricitinib improved symptoms of RA in the RA-BUILD trial, a Phase 3 study of baricitinib in patients with moderately to severely active RA, refractory to or intolerant to csDMARDs. As well as providing a short-term (24 weeks) benefit, there appeared to be joint damage benefit, considered a marker of long-term disability. RA-BUILD was a 24-week randomised, double-blind, placebo-controlled parallel-group study. Patients were randomised 1:1:1 to receive once-daily doses of placebo (n=228) or bari...

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 m...

Arthritis Rheumatol 2016. DOI 10.1002/art.39953. Accepted article

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) to MTX 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, baricit...

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 baricitinib, fo...
