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 fro...

Evaluation of Pneumococcal and Tetanus Vaccine Responses in Patients with Rheumatoid Arthritis Receiving Baricitinib: Results from a Long-Term Extension Trial Substudy

Winthrop KL, Bingham CO III, Komocsar WJ, Bradley J, Issa M, Klar R, Kartman CE.
Arthritis Res Ther. 2019 Apr 18;21(1):102

Approximately two thirds of long-term BARI treated patients achieved satisfactory humoral and functional responses to 13-serotype pneumococcal conjugate vaccine (PCV-13), whereas tetanus toxoid vaccine (TTV) responses were less robust. Both RA management guidelines and recommendations suggest vaccinating patients with RA against pneumococcal disease with PCV-13 and PPSV-23. The inhibition of the JAK mediated signal transduction pathways in RA treatment could diminish vaccine responses. Given t...

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

Harigai M, Takeuchi T, Smolen JS, Winthrop KL, Nishikawa A, Rooney TP, Saifan CG, Issa M, Isaka Y, Akashi N, Ishii T, Tanaka Y.
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 th...

Cardiovascular Safety During Treatment with Baricitinib in Rheumatoid Arthritis

Taylor PC, Weinblatt ME, Burmester GR, Rooney TP, Witt S, Walls CD, Issa M, Salinas CA, Saifan C, Zhang X, Cardoso A, González-Gay MA, Takeuchi T.
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&nd...

Characterization and Changes of Lymphocyte Subsets in Baricitinib-Treated Patients With Rheumatoid Arthritis: An Integrated Analysis.

Tanaka Y, McInnes IB, Taylor PC, Byers NL, Chen L, de Bono S, Issa M, Macias WL, Rogai V, Rooney TP, Schlichting DE, Zuckerman SH, Emery P.
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 s...
