Janus kinases (JAKs) are essential mediators of downstream signaling pathways in many inflammatory and autoimmune diseases. This review summarizes current clinical data on first- and second-generation JAK inhibitors (jakinibs) and discusses their use for the treatment of immune and inflammatory conditions.First generation jakinibs such as tofacitinib, baricitinib, and ruxolitinib, non-selectively inhibit JAK-dependent pro-inflammatory cytokines, which are major contributors to immunopathology.

In this pooled analysis investigating liver enzyme abnormalities and hepatic adverse events (AEs) during long-term tocilizumab (TCZ) treatment for RA in clinical trials, although transaminase elevations were frequent, rates of hepatic serious AEs remained low. Data were pooled from patients who received ≥1 dose of IV TCZ with or without DMARDs in Phase 3 or 4 clinical trials, long-term extensions, and a pharmacology study.A total of 4171 patients were included in the all-exposure population with...

Safety and Efficacy of Baricitinib through 128 Weeks in an Open-label, Longterm Extension Study in Patients with Rheumatoid Arthritis

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. Rate...

A Comparison of Discontinuation Rates of Tofacitinib and Biologic Disease-modifying Anti-rheumatic Drugs in Rheumatoid Arthritis: a Systematic Review and Bayseian Network Meta-analysis Regression

Based on a Bayesian network meta-analysis (NMA) in patients with RA who previously showed failure with csDMARDs or biologics, discontinuation rates between tofacitinib (TOF) and biologics (TNFis, abatacept [ABT], rituximab [RTX] and tocilizumab [TCZ]) differed based on previous treatments and reasons for discontinuation.Data were collected from randomised controlled trials (RCT) found from literature searches from the Cochrane Central Register of Controlled Trials (CENTRAL) and MEDLINE. Disconti...

Because non-melanoma skin cancer (NMSC) is one of the most common malignancies associated with RA immunomodulatory therapies, this analysis looked to determine the rate of NMSC incidence per 100 patient-years in patients with RA receiving TOF in the clinical trial programme. The Phase 1, 2, and 3 IRs (combined) for both TOF 5- and 10 mg were low and comparable to those of adalimumab, MTX and placebo, IRs remained stable over time. TOF doses used in the 2 Phase 1; 8 Phase 2; and 6 Phase 3 studies...

This analysis of exposure to tofacitinib, an oral JAKi for the treatment of RA, for up to 8.5 years allowed estimation of safety events with improved precision versus previous tofacitinib reports. Adverse events were generally stable over time; no new safety signals were observed compared with previous tofacitinib reports.Data were collated into an integrated safety summary of tofacitinib in adult patients with active RA, and included data spanning the tofacitinib clinical programme: from 2 Pha...

Efficacy and Safety of Tofacitinib Monotherapy, Tofacitinib with Methotrexate, and Adalimumab with Methotrexate in Patients with Rheumatoid Arthritis (ORAL Strategy): A Phase 3b/4, Double-Blind, Head-To-Head, Randomised Controlled Trial

In this first head-to-head non-inferiority trial assessing a JAKi ± MTX directly compared with a TNFi + MTX in patients with RA, tofacitinib (TOF) + MTX showed non-inferiority to adalimumab (ADA) + MTX. Non-inferiority was not shown for TOF monotherapy versus TOF + MTX, or versus ADA + MTX.In this 52-week study, MTX-inadequate responder (IR) patients were randomised 1:1:1 to receive TOF 5 mg BID monotherapy, TOF 5 mg BID + MTX or ADA 40 mg every other week + MTX. The primary endpoint, ACR50 resp...

This Cochrane systemic review and network meta-analysis looked at the benefits and harms of biologics or tofacitinib in patients with RA not previously treated with MTX.Using data from 19 RCTs including 6,485 participants, the review found that biologics (abatacept, adalimumab, etanercept, golimumab, infliximab, rituximab) in combination with MTX improved signs and symptoms of RA (ACR50) and increased the chances of remission (DAS <1.6 or DAS28 <2.6). There was also some evidence of an improveme...

This study showed that in patients who achieved low disease activity (LDA), it is possible to discontinue tofacitinib without flare in approximately one-third of patients. Patients from the tofacitinib Phase 3 programme and long-term extension study were enroled. Discontinuation was based on physician-patient decision making with informed consent. The primary endpoint was the proportion of patients who remained tofacitinib free at post-treatment Week 52. Of 64 patients treated with tofacitinib w...
