Thromboembolism with Janus Kinase (JAK) Inhibitor for Rheumatoid Arthritis: How Real is the Risk?

Drug Safety 2018 Jul;41(7):645–53

Current data suggests that JAK inhibitors may increase the risk of thromboembolism and pulmonary thrombosis (PT) in RA.Two JAK inhibitors – baricitinib (BARI) and tofacitinib (TOF) – are considered effective treatments for RA, however, there are concerns about the thromboembolic risks associated with them. In August 2017, the summary of product characteristics for BARI was revised to include a warning of developing DVT and pulmonary embolism (PE), with recommendations that BARI should be used wi...

Effects of Baricitinib on Radiographic Progression of Structural Joint Damage at 1 year in Patients with Rheumatoid Arthritis and an Inadequate Response to Conventional Synthetic Disease-modifying Antirheumatic Drugs

RMD Open. 2018 May 8;4(1):e000662. DOI: 10.1136/rmdopen-2018-000662

Once daily baricitinib (BARI) inhibited radiographic progression of structural joint damage in patients with an inadequate response or intolerance to csDMARDs over 48 weeks.Current treatment goals aim to use DMARDs to inhibit structural joint damage and prevent long-term functional disability. In RA-BUILD¹, BARI was shown to significantly reduce radiographic joint damage progression in patients with active RA, with an intolerance or inadequate response to csDMARDs. Here, the authors report the l...

Analysis of Spontaneous Postmarket Case Reports Submitted to the FDA Regarding Thromboembolic Adverse Events and JAK Inhibitors

Drug Saf 2018 Apr; 41(4):357–61 DOI: 10.1007/s40264-017-0622-2

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...

Baricitinib for Previously Treated Moderate or Severe Rheumatoid Arthritis: An Evidence Review Group Perspective of a NICE Single Technology Appraisal

Pharmacoeconomics 2018 Jul; 36(7):769–78

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...

Response to Baricitinib based on Prior Biologic Use in Patients with Refractory Arthritis

Rheumatology (Oxford) 2018 May; 57(5):900-908

Baricitinib (BARI) 2 or 4 mg had a beneficial treatment effect on patients with moderate to severe RA compared with placebo (PBO), irrespective of the number or nature of prior patient bDMARD use. The current therapeutic target for patients with established RA is low disease activity, but many patients fail to achieve this due to inadequate responses to DMARD therapies. With this patient population growing, therapies for these patients are considered one of the greatest unmet needs in RA. This s...

Professor Iain McInnes Reviews the Most Important Papers from 2017

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

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

Nat Rev Drug Discov 2017;16:843–62 DOI: 10.1038/nrd.2017.201

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...

Safety and Efficacy of Baricitinib in Elderly Patients with Rheumatoid Arthritis

RMD Open. 2017; 3(2): e000546. doi: 10.1136/rmdopen-2017-000546

In this post hoc analysis of pooled data from two randomised controlled trials, RA-BUILD and RA-BEAM, age was shown not to be a contraindication for use of baricitinib. Patients in RA-BUILD were csDMARD-inadequate responder(IR) patients who received an oral placebo or 2 mg or 4 mg baricitinib once daily. Patients in RA-BEAM were MTX-IR patients and received an oral placebo, 4 mg baricitinib once daily or subcutaneous adalimumab every 2 weeks. Efficacy and safety of baricitinib in elderly patient...

Patient-reported Outcomes of Baricitinib in Patients with Rheumatoid Arthritis and No or Limited Prior Disease-modifying Antirheumatic Drug Treatment

Arthritis Res Ther. 2017 Sep 18;19(1):208

RA-BEGIN was a Phase 3, double-blind randomised active comparator-controlled study to evaluate baricitinib as monotherapy or in combination with MTX in patients with active RA who were naïve to csDMARDS and bDMARDS. In this analysis of the RA-BEGIN study, baricitinib alone or with MTX when used as initial therapy resulted in significant improvements in most patient-reported outcome measures compared with MTX. At baseline, study participants had active RA, impaired physical function, moderate le...

Patient-reported Outcomes from a Phase 3 Study of Baricitinib versus Placebo or Adalimumab in Rheumatoid Arthritis: Secondary Analyses from the RA-BEAM Study

Ann Rheum Dis 2017;76(11):1853-1861. doi: 10.1136/annrheumdis-2017-211259

This paper describes the patient-reported outcome (PRO) data collected in RA-BEAM, a Phase 3 study of baricitinib compared with both placebo and adalimumab in patients with RA and an inadequate response to MTX.PRO measures evaluated include health-related quality of life (HRQOL), physical function, disability, fatigue, sleep, mental health status, work productivity and work activity impairment. The RA-BEAM study demonstrated that patients treated with baricitinib experienced a greater improveme...
