Baricitinib Induces LDL-C and HDL-C Increases in Rheumatoid Arthritis: A Meta-Analysis of Randomized Controlled Trials

Lipids Health Dis. 2019 Feb 18;18(1):54.

This study confirmed that BARI induced a stable dose-dependent increase in LDL-C and HDL-C levels. There was no significant difference of CV risk between BARI and placebo groups.High risk of CV events is strongly associated with RA. Mechanisms underlying the excess risk of CV events in RA remains unclear. This study aims to provide additional insight into the clinical safety of BARI, focusing on the effects of BARI on LDL-C and HDL-C levels and CV risk. A Cochrane analysis was performed on studi...

Network Meta‐Analysis of Tofacitinib versus Biologic Treatments in Moderate‐to‐Severe Rheumatoid Arthritis Patients

J Clin Pharm Ther. 2019 Jun;44(3):384-396.

This study suggests that many bDMARDs and tsDMARDs can be considered equivalent therapeutic alternatives in bDMARD-naïve RA patients, with inadequate response to csDMARDs.In the absence of randomised controlled trials comparing drugs, indirect comparisons and network meta-analysis may provide information to help select an optimal treatment alternative. In this network meta-analysis, 27 randomized controlled trials were analysed to assess the possibility that some drugs on the market may be consi...

Comparisons of Hepatitis C Viral Replication in Patients with Rheumatoid Arthritis Receiving Tocilizumab, Abatacept and Tofacitinib Therapy

Ann Rheum Dis. 2019 Jun;78(6):849-850.

Tocilizumab (TCZ), abatacept (ABA) and tofacitinib (TOF) appear to have no major safety concerns for treatment of RA patients with hepatitis C virus (HCV) infections.HCV is an infectious disease which continues to present a major therapeutic challenge for clinicians in treating patients with RA. Previous reports demonstrate that the use of TNF targeted therapies in RA patients with HCV infections appear to have no major safety concerns. During short-term therapy with TCZ and ABA, data has shown ...

Tofacitinib in Combination with Methotrexate in Patients with Rheumatoid Arthritis: Clinical Efficacy, Radiographic and Safety Outcomes from the 24-Month Phase 3 ORAL Scan Study

Arthritis Rheumatol. 2019 Jun;71(6):878-891

RA patients receiving TOF 5 or 10 mg BID plus MTX showed sustained clinical and radiographic treatment effects through months 12-24. The safety profile was consistent with previous TOF studies. The 12-month data from the ORAL Scan study have been previously reported. This report assesses durability of responses, including structural damage progression, and safety with TOF through 24 months. Patients were randomized 4:4:1:1 to receive TOF 5 or 10 mg BID, or PBO advanced to TOF with stable, backgr...

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...

A Pooled analysis of the Safety of Tofacitinib as Monotherapy or in Combination with Background Conventional Synthetic Disease-Modifying Antirheumatic Drugs in a Phase 3 Rheumatoid Arthritis Population

Semin Arthritis Rheum. 2018 Dec;48(3):406-415. doi: 10.1016/j.semarthrit.2018.07.006.

In this pooled analysis of Phase 3 Tofacitinib (TOF) trials, safety profiles were generally similar between patients receiving monotherapy and combination therapy. Although selected adverse events of interest showed lower incidence rates (IRs) for TOF monotherapy patients.TOF has been studied as monotherapy and in combination with csDMARDs. In this post-hoc analysis, data were pooled from six Phase 3 TOF studies in RA patients to further examine the safety profile when used as monotherapy or in ...

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...

Comparative Risk of Venous Thromboembolism with Tofacitinib versus Tumour Necrosis Factor Inhibitor: A Cohort study of Rheumatoid Arthritis Patients

Desai RJ, et al. Arthritis Rheumatol. 2019 June;71(6):892-900.

Occurrences of venous thromboembolism (VTE) in 50, 865 RA patients initiating Tofacitinib (TOF) or a TNF inhibitor (TNFi) was infrequent. No significant risk of VTE for TOF versus TNFi was observed.Safety concerns of JAK inhibitor BARI include potentially increased risk of VTE at the higher 4 mg dose. It’s unclear if this is attributable to JAK-inhibition and extends to TOF. This study compared the risk of VTE with TOF, versus TNFi in real-world settings with RA patients.RA patients initiating T...

Professor Iain McInnes Reviews the Most Notable Papers from 2018

Please click the links below to go to the CSF review of each paper

2018 brought a wealth of new data in cytokine signalling and IL-6 that helps inform current clinical practice and brings the promise of new options in the future. There was good data on the use of sub cutaneous tocilizumab as well as strategies in early RA and for methotrexate tapering. For the currently marketed JAK inhibitors, tofacitinib and baricitinib, continuous long-term efficacy and safety data further support its current use and applications. On the development side, the outcomes of the...

Safety and Efficacy of Baricitinib in Patients Receiving Conventional Synthetic Disease-Modifying Antirheumatic Drugs or Corticosteroids

Rheumatol Ther 2018 Dec;5(2):525-536. DOI 10.1007/s40744-018-0128-0

Baricitinib (BARI) in combination with MTX and concomitant csDMARDs was shown to be efficacious, regardless of corticosteroid use in RA patients. MTX is prescribed to most RA patients but concomitant csDMARDs and/or corticosteroids can be added. This study assessed the efficacy and safety of BARI in two arms; with/without corticosteroids and; with MTX only/MTX plus csDMARD/csDMARDs only. Baseline characteristics and adverse reactions were also compared. Data were pooled from two phase 3 studies ...
