Infections in Baricitinib Clinical Trials for Patients with Active Rheumatoid Arthritis
Annals of the Rheumatic Diseases, May 2020
Baricitinib, an oral selective JAK1 and JAK2 inhibitor,8 demonstrated significant clinical efficacy in phase 3 RA trials. Pooled data from these trials, including a long-term extension (LTE), inform the safety profile for baricitinib, mainly to evaluate the incidence of infection in patients with active rheumatoid arthritis (RA), with a focus on serious infection, tuberculosis (TB), herpes zoster (HZ) and opportunistic infection (OI). The data collected were from eight double-blind randomised tr...Efficacy and Safety of Long-Term Baricitinib With and Without Methotrexate for the Treatment of Rheumatoid Arthritis: Experience With Baricitinib Monotherapy Continuation or After Switching From Methotrexate Monotherapy or Baricitinib Plus Methotrexate.
Arthritis Care Res (Hoboken) 2020;72(8):1112-1121
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, pati...Temporary Interruption of Baricitinib: Characterization of Interruptions and Effect on Clinical Outcomes in Patients With Rheumatoid Arthritis
Arth Res Ther 2020;22:115 doi.org/10.1186/s13075-020-02199-8
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 cou...Safety Profile of Baricitinib For the Treatment of Rheumatoid Arthritis Over a Median of 3 Years of Treatment: An Updated Integrated Safety Analysis
Lancet Rheumatol 2020;2:e347–57
RA is a chronic, life-long disease requiring long-term treatment. As such, it is important to understand the long-term safety profile of DMARDs. In this analysis, baricitinib maintained a stable safety profile during long-term exposure. This baricitinib safety analysis included integrated data from nine Phase 3, 2, and 1b clinical trials, and one long-term extension, with data up to 360 weeks. 3700 patients were included, with maximum follow-up of almost 7 years – representing an additional 3,54...Baricitinib In Patients with Rheumatoid Arthritis With Inadequate Response to Methotrexate: Results From A Phase 3 Study
Clin Exp Rheumatol . Jul-Aug 2020;38(4):732-741. Epub 2020 May 20.
This study conducted mainly in Chinese patients with RA, and an inadequate response to MTX, showed that baricitinib 4mg was associated with significant improvements and consistent with the findings from previous clinical trials.The efficacy and safety of baricitinib have been assessed in several clinical trials, predominantly in Caucasian populations. However, evidence on the efficacy and safety of baricitinib in Chinese patients is limited, with only one of the main clinical trial program studi...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...Clinical Outcomes in Patients Switched from Adalimumab to Baricitinib Due to Non-Response and/or Study Design: Phase III Data in Patients with Rheumatoid Arthritis
Ann Rheum Dis. 2019 Jul;78(7):890-898.
Switching from ADA to BARI without a lengthy washout period can be executed with acceptable safety and tolerability and was associated with maintained disease control. Switching therapies in RA is commonplace in myriad scenarios including inadequate responses, intolerances and patient preference. Assessing the safety and efficacy of new treatments such as BARI, in the context of use as a replacement therapy, is beneficial. A previous study (RA-BEACON) has demonstrated that safely switching from ...Safety Profile of Baricitinib in Japanese Patients with Active Rheumatoid Arthritis with Over 1.6 Years Median Time in Treatment: An Integrated Analysis of Phase 2 and 3 Trials
Mod Rheumatol. 2019 Feb 20:1-23. DOI: 10.1080/14397595.2019.1583711
In this integrated analysis, BARI showed an acceptable safety profile in Japanese patients with up to 3.2 years of exposure. Other than incidences of herpes zoster (HZ), no major differences were noted with BARI safety in Japanese patients with RA, compared to the patients in the integrated database.BARI has previously demonstrated significant clinical efficacy and acceptable safety. Japanese patients who participated in the BARI clinical development programme, were comparable to those from the ...Cardiovascular Safety During Treatment with Baricitinib in Rheumatoid Arthritis
Arthritis Rheumatol. 2019 Jul;71(7):1042-1055.
This study indicates no association between exposure to BARI and MACE, arterial thrombotic events (ATE), or congestive heart failure (CHF). Overall IRs for venous thromboembolic event (VTE) in BARI-treated patients falls within the reported range for patients with RA.RA patients have a greater risk of cardiovascular (CV) diseases of arterial ischemic origin, and an increased risk of VTE. Studied frequencies of thromboembolic events in RA populations in the last decade has been reported as 2–3x h...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...
