tofacitinib and Spondylarthropathies

Janus kinase inhibitors (JAKi) have been approved for use in various immune-mediated inflammatory diseases. With five agents licensed, it was timely to summarise the current understanding of JAKi use based on a systematic literature review (SLR) on efficacy and safety.. Existing data were evaluated by a steering committee and subsequently reviewed by a 29 person expert committee leading to the formulation of a consensus statement that may assist the clinicians, patients and other stakeholders once the decision is made to commence a JAKi. The committee included patients, rheumatologists, a gastroenterologist, a haematologist, a dermatologist, an infectious disease specialist and a health professional. The SLR informed the Task Force on controlled and open clinical trials, registry data, phase 4 trials and meta-analyses. In addition, approval of new compounds by, and warnings from regulators that were issued after the end of the SLR search date were taken into consideration.. The Task Force agreed on and developed four general principles and a total of 26 points for consideration which were grouped into six areas addressing indications, treatment dose and comedication, contraindications, pretreatment screening and risks, laboratory and clinical follow-up examinations, and adverse events. Levels of evidence and strengths of recommendations were determined based on the SLR and levels of agreement were voted on for every point, reaching a range between 8.8 and 9.9 on a 10-point scale.. The consensus provides an assessment of evidence for efficacy and safety of an important therapeutic class with guidance on issues of practical management.

JAK inhibitor therapies are effective treatment options for immune-mediated inflammatory diseases (IMIDs), but their use has been limited by venous thromboembolism (VTE) risk warnings from licensing authorities. We undertook this study to evaluate the VTE risk of JAK inhibitors in patients with IMIDs.. Systematic searches of Medline and Embase databases from inception to September 30, 2020 were conducted. Phase II and phase III double-blind, randomized controlled trials (RCTs) of JAK inhibitors at licensed doses were included in our analyses. RCTs with no placebo arm, long-term extension studies, post hoc analyses, and pooled analyses were excluded. Three researchers independently extracted data on exposure to JAK inhibitors or placebo and VTE events (e.g., pulmonary embolism [PE] and deep vein thrombosis [DVT]) and assessed study quality.. A total of 42 studies were included, from an initial search that yielded 619. There were 6,542 JAK inhibitor patient exposure years (PEYs) compared to 1,578 placebo PEYs. There were 15 VTE events in the JAK inhibitor group and 4 in the placebo group. The pooled incidence rate ratios (IRRs) of VTE, PE, and DVT in patients receiving JAK inhibitors were 0.68 (95% confidence interval [95% CI] 0.36-1.29), 0.44 (95% CI 0.28-0.70), and 0.59 (95% CI 0.31-1.15), respectively.. This meta-analysis of RCT data defines the VTE risk with JAK inhibitors as a class in IMID patients. The pooled IRRs do not provide evidence that support the current warnings of VTE risk for JAK inhibitors. These findings will aid continued development of clinical guidelines for the use of JAK inhibitors in IMIDs.

There was a substantial progress in the field of spondyloarthritis (SpA) in terms of understanding disease mechanisms, early diagnosis, and improved treatment. Nonetheless, several unresolved questions and unmet needs do remain.. Although the diagnostic delay in axial SpA is decreasing, it remains one of the longest in rheumatology. Application of referral strategies, as well as correct application and interpretation of imaging finding in the clinical context, is the main key to early diagnosis of axial SpA. Tumor necrosis factor (TNF) alpha and interleukin (IL)-17 represent currently two major treatment targets in SpA, while other promising targets such as IL-23 or IL-6 failed in clinical trials. There is an unmet need for strategy trials to optimize and to individualize treatment in SpA. The role of Janus kinases and their blockade in SpA is still to be explored. TNF blockade showed efficacy in peripheral SpA, and other targets (IL-17 and IL-23) should be investigated in clinical trials. Early, effective, and long-term suppression of inflammation is currently the best method to prevent structural damage progression in the spine in axial SpA, while specific effects of IL-17 blockade and of nonsteroidal anti-inflammatory drugs on new bone formation are still being investigated. This review summarizes the recent advances in diagnosis and treatment of SpA and discusses the current unmet needs in the field.

To update evidence-based recommendations for the treatment of patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (SpA).. We conducted updated systematic literature reviews for 20 clinical questions on pharmacologic treatment addressed in the 2015 guidelines, and for 26 new questions on pharmacologic treatment, treat-to-target strategy, and use of imaging. New questions addressed the use of secukinumab, ixekizumab, tofacitinib, tumor necrosis factor inhibitor (TNFi) biosimilars, and biologic tapering/discontinuation, among others. We used the Grading of Recommendations, Assessment, Development and Evaluation methodology to assess the quality of evidence and formulate recommendations and required at least 70% agreement among the voting panel.. Recommendations for AS and nonradiographic axial SpA are similar. TNFi are recommended over secukinumab or ixekizumab as the first biologic to be used. Secukinumab or ixekizumab is recommended over the use of a second TNFi in patients with primary nonresponse to the first TNFi. TNFi, secukinumab, and ixekizumab are favored over tofacitinib. Co-administration of low-dose methotrexate with TNFi is not recommended, nor is a strict treat-to-target strategy or discontinuation or tapering of biologics in patients with stable disease. Sulfasalazine is recommended only for persistent peripheral arthritis when TNFi are contraindicated. For patients with unclear disease activity, spine or pelvis magnetic resonance imaging could aid assessment. Routine monitoring of radiographic changes with serial spine radiographs is not recommended.. These recommendations provide updated guidance regarding use of new medications and imaging of the axial skeleton in the management of AS and nonradiographic axial SpA.
