Thromboembolic-related adverse events (AEs) were, in general, not considered a class-wide safety concern after analysis of tofacitinib (TOF) and ruxolitinib (RUX) clinical data, though pulmonary thrombosis is considered a potential class-wide safety issue and portal vein thrombosis was considered a potential safety issue for RUX. During analysis of baricitinib (BARI) clinical trial data, the FDA expressed concerns regarding thromboembolic events. Following this, the CHMP have recently added a pr...

In this National Institute for Health and Care (NICE) single technology appraisal of baricitinib (BARI) monotherapy and combination therapy with methotrexate (MTX), BARI efficacy was considered comparable to bDMARDs and a cost-effective use of National Health Service (NHS) resources.NICE is an independent organisation responsible for providing national guidance on health technologies in England. To be recommended by NICE, the company must provide evidence to prove BARI’s effectiveness, both clin...

In this National Institute for Health and Care (NICE) single technology appraisal of tofacitinib (TOF) plus methotrexate (MTX), TOF had similar efficacy and comparable costs to recommended bDMARDs plus MTX in patients with RA. NICE is an independent organisation responsible for providing national guidance on health technologies in England. To be recommended by NICE, the company must provide evidence to prove TOF’s effectiveness, both clinically and costly. This evidence based review, reports the...

Worldwide, 3-year, Post-Marketing Surveillance Experience with Tofacitinib in Rheumatoid Arthritis

This real-world analysis of tofacitinib (TOF) revealed that AEs reported by patients with RA from 2012 to 2015 were consistent with the known safety profile of TOF – no new safety risks were identified.As of August 2017, it is estimated that more than 102 000 patients worldwide have received TOF, but TOF safety has not been evaluated in patients with real-world experience. This analysis addressed this – by evaluating the safety of TOF from post-marketing surveillance (PMS) reports from patients ...

2017 was a successful year for rheumatoid arthritis research, with some key advances in JAK inhibitors and IL-6 inhibitors, as outlined below. - Tofacitinib was suggested as a potential treatment for psoriatic arthritis, and NICE recommended tofacitinib as a treatment for moderate to severe rheumatoid arthritis - Baricitinib studies supported the potential use of baricitinib as a treatment for rheumatoid arthritis - Filgotinib Phase 2 studies suggested that filgotinib could be effective a...

JAK Inhibition as a Therapeutic Strategy for Immune and Inflammatory Diseases

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. T...

The results of this analysis of patients with herpes zoster (HZ) within the global tofacitinib (TOF) RA programme suggest that there is likely to be a greater HZ risk in patients receiving TOF and glucocorticoids compared with patients receiving TOF monotherapy.The global TOF RA development programme comprised 2 Phase 1, 9 Phase 2, 6 Phase 3 and 2 long-term extension studies. These studies included 6192 patients; data were reviewed to identify cases of HZ. Crude incidence rates of number of pati...

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...

Pathogenetic Insights from the Treatment of Rheumatoid Arthritis

This review paper examines the understanding gained from looking at the effects of specific immune interventions in the treatment of RA.The introduction of novel IL-6 agents has provided the ideal opportunity to explore the distinct effect of cytokine inhibition, as opposed to receptor inhibition, at the molecular level. Mechanistic insights into TNF could also be obtained in the future with advanced molecular and informatics approaches, and future biopsy studies will be important to explore the...

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...
