Comparative Efficacy and Safety of Peficitinib 25, 50, 100, and 150 mg in Patients with Active Rheumatoid Arthritis: A Bayesian Network Meta‑Analysis of Randomized Controlled Trials

Clin Drug Investig .2020 Jan;40(1):65-72. doi: 10.1007/s40261-019-00863-9.

PEF 50, 100, and 150 mg once daily was effective in treating active RA, without causing a significant risk for AEs.Intracellular pathways, including JAK and Tyk-2, are critical for immune cell activation, pro-inflammatory cytokine production, and cytokine signaling. PEF has been developed for use in RA, but the comparative efficacy and safety of regimens and dosages has not been established. A Bayesian network meta-analysis was conducted to combine direct and indirect evidence to assess the rela...

Tofacitinib Modulates the VZV-specific CD4+ T Cell Immune Response in vitro in Lymphocytes of Patients with Rheumatoid Arthritis

Rheumatology (Oxford) 2019;58(11):2051–60

TOF significantly modulated the Th1 response to Varicella-zoster-virus (VZV). The poor VZV-specific cellular immune responses in patients with RA may be considered in recommendations regarding appropriate vaccination strategies for enhancing the VZV-specific Th1 response.Previous studies have shown that treatment with JAKinibs increases HZ incidence compared with conventional DMARDs. This cross-sectional in vitro study aimed to investigate the effect of TOF on the VZV-specific T cell immune resp...

Impact of Janus Kinase Inhibitors on Risk of Cardiovascular Events in Patients with Rheumatoid Arthritis: Systematic Review and Meta-Analysis of Randomised Controlled Trials

Ann Rheum Dis. 2019 Aug;78(8):1048-1054.

Existing evidence from RCTs indicated no significant change in CV risk for JAK inhibitor (JAKinib) treated RA patients in a short-term perspective compared to placebo.Patients with RA have an elevated risk of CV morbidity and mortality, which cannot be fully explained by traditional CV risk factors. Reaching remission or LDA in order to reduce CV events (CVE) is encouraged in the current EULAR recommendations. JAKinibs and their roles in the modulation of CV risk remain undetermined. This study ...

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

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 the...
