ObjectiveWe undertook this phase III study to evaluate baricitinib, an orally administered JAK‐1/JAK‐2 inhibitor, as monotherapy or combined with methotrexate (MTX) compared to MTX monotherapy in patients with active rheumatoid arthritis (RA) who had received no or minimal conventional synthetic disease‐modifying antirheumatic drugs (DMARDs) and who were naive to biologic DMARDs.MethodsA total of 588 patients were randomized 4:3:4 to receive MTX monotherapy (once weekly), baricitinib monotherapy (4 mg once daily), or the combination of baricitinib and MTX for 52 weeks. The primary end point assessment was a noninferiority comparison of baricitinib monotherapy to MTX monotherapy based on the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 24.ResultsThe study met its primary objective. Moreover, baricitinib monotherapy was found to be superior to MTX monotherapy at week 24, with a higher ACR20 response rate (77% versus 62%; P ≤ 0.01). Similar results were observed for combination therapy. Compared to MTX monotherapy, significant improvements in disease activity and physical function were observed for both baricitinib groups as early as week 1. Radiographic progression was reduced in both baricitinib groups compared to MTX monotherapy; the difference was statistically significant for baricitinib plus MTX. The rates of serious adverse events (AEs) were similar across treatment groups, while rates of some treatment‐emergent AEs, including infections, were increased with baricitinib plus MTX. Three deaths were reported, all occurring in the MTX monotherapy group. Malignancies, including nonmelanoma skin cancer, were reported in 1 patient receiving MTX monotherapy, 1 receiving baricitinib monotherapy, and 4 receiving baricitinib plus MTX.ConclusionBaricitinib alone or in combination with MTX demonstrated superior efficacy with acceptable safety compared to MTX monotherapy as initial therapy for patients with active RA.
Objectives:To develop evidence-based recommendations for the use of methotrexate in daily clinical practice in rheumatic disorders.Methods:751 rheumatologists from 17 countries participated in the 3E (Evidence, Expertise, Exchange) Initiative of 2007–8 consisting of three separate rounds of discussions and Delphi votes. Ten clinical questions concerning the use of methotrexate in rheumatic disorders were formulated. A systematic literature search in Medline, Embase, Cochrane Library and 2005–7 American College of Rheumatology/European League Against Rheumatism meeting abstracts was conducted. Selected articles were systematically reviewed and the evidence was appraised according to the Oxford levels of evidence. Each country elaborated a set of national recommendations. Finally, multinational recommendations were formulated and agreement among the participants and the potential impact on their clinical practice was assessed.Results:A total of 16 979 references was identified, of which 304 articles were included in the systematic reviews. Ten multinational key recommendations on the use of methotrexate were formulated. Nine recommendations were specific for rheumatoid arthritis (RA), including the work-up before initiating methotrexate, optimal dosage and route, use of folic acid, monitoring, management of hepatotoxicity, long-term safety, mono versus combination therapy and management in the perioperative period and before/during pregnancy. One recommendation concerned methotrexate as a steroid-sparing agent in other rheumatic diseases.Conclusions:Ten recommendations for the use of methotrexate in daily clinical practice focussed on RA were developed, which are evidence based and supported by a large panel of rheumatologists, enhancing their validity and practical use.
Background: Biologic disease modifying anti-rheumatic drugs (bDMARDs) are recommended for radiographic axial spondyloarthritis (r-axSpA), otherwise known as ankylosing spondylitis, when conventional therapies fail. We report efficacy and safety results of a Phase 3 study of ixekizumab, a high-affinity monoclonal antibody that selectively targets IL-17A, in bDMARDnaïve patients with r-axSpA. Methods: In this randomized, double-blind, Phase 3 study, adult patients with inadequate response/intolerance to NSAIDs, an established diagnosis of r-axSpA, and with radiographic sacroiliitis centrally defined by modified New York criteria and ≥1 spondyloarthritis feature according to Assessment of Spondyloarthritis International Society (ASAS) criteria were recruited from 84 sites (12 countries) in Europe, Asia, and North America. Patients were randomized 1:1:1:1 using a computer-generated random sequence to 80 mg subcutaneous ixekizumab every two (Q2W) or four (Q4W) weeks, 40 mg adalimumab Q2W (active reference arm), or placebo. The primary endpoint was the proportion of patients achieving an ASAS40 response at Week 16. Findings: Between June 20, 2016 and August 22, 2017, 341 patients were randomized to placebo (N=87), adalimumab (N=90), ixekizumab Q2W (N=83), or ixekizumab Q4W (N=81). At Week 16, significantly more patients achieved ASAS40 with ixekizumab Q2W (n=43, 51•8%, p<0•0001), ixekizumab Q4W (n=39, 48•1%, p<0•0001), and adalimumab (n=32, 35•6%; p=0•0053) versus placebo (n=16, 18•4%). One serious infection occurred in each of the ixekizumab Q2W (1•2%), ixekizumab Q4W (1•2%), and adalimumab (1•1%) arms; none were reported with placebo. One (1•1%) Candida infection occurred in the adalimumab arm and one (1•2%) patient receiving ixekizumab Q2W was adjudicated as having probable Crohn's disease. No opportunistic infections, malignancies, or deaths occurred. Interpretation: Each dosing regimen of ixekizumab was superior to placebo for improving r-axSpA signs and symptoms in bDMARD-naïve patients; the safety profile was consistent with previous studies of ixekizumab. The adalimumab control arm performed as expected. Funding: Eli Lilly and Company Research in context Evidence before this study Pubmed was searched using the terms "ankylosing spondylitis", "axial spondyloarthritis", and "disease-modifying anti-rheumatic drugs", including articles through May 30, 2018. Axial spondyloarthritis (axSpA) is a chronic immune-mediated disease characterized by inflammation of the spine and sacroiliac joint (SIJ), peripheral joint involvement, extra articular manifestations, and a strong genetic association with human leukocyte antigen (HLA)-B27. Radiographic axSpA (r-axSpA) was previously classified as ankylosing spondylitis (AS) in 1984 and updated to r-axSpA as part of the ASAS criteria. Both criteria sets require the same radiographically confirmed structural damage to the sacroiliac joint as well as at least one accompanying clinical element. Recommendations for the management of r-axSpA generally include exercise and physiothera...
Objective. To assess the efficacy, safety, and tolerability of etoricoxib, a cyclooxygenase 2 (COX-2) selective inhibitor, administered continuously over 52 weeks for the treatment of ankylosing spondylitis (AS).Methods. This 2-part, multicenter, double-blind, parallel-group, 52-week study evaluated 2 doses of etoricoxib (90 and 120 mg) compared with naproxen at 1,000 mg. A 6-week, active-comparator-and placebocontrolled period (part I) was followed by a 46-week active-comparator-controlled period (part II). The primary outcome measures (on 100-mm visual analog scales) were patient's assessment of spine pain, patient's global assessment of disease activity, and the Bath Ankylosing Spondylitis Functional Index.Results. Of the 387 patients randomized to receive treatment, 301 (77.8%) completed part I and 284 (75.9%) completed part II. Compared with placebo over 6 weeks, those receiving 90 mg etoricoxib, 120 mg etoricoxib, and naproxen demonstrated significantly (P < 0.001) greater improvement in all primary end points; treatment effects (expressed as the difference in least squares mean change versus placebo) were 21-29 mm for spine pain, 18-25 mm for disease activity, and 11-15 mm for function. Compared with patients receiving naproxen, significantly greater improvement in all primary end points was demonstrated in the combined group receiving either 90 mg etoricoxib or 120 mg etoricoxib over 6 weeks, in each individual etoricoxib treatment group over 6 weeks, and in the combined etoricoxib group over 1 year (all P < 0.05); results for secondary and exploratory end points were generally consistent with those from the primary analysis. Among all groups, there were no significant differences in the incidence of overall clinical, drug-related, or serious adverse experiences (AEs) and discontinuations due to AEs. Safety observations during part II were generally consistent with those in part I.Conclusion. Etoricoxib at doses of 90 mg and 120 mg demonstrated superior efficacy compared with placebo over 6 weeks, and compared with naproxen over 1 year. These study results demonstrate that etoricoxib is generally safe, well-tolerated, and efficacious for the treatment of AS.Ankylosing spondylitis (AS) is a chronic inflammatory autoimmune disease that is characterized by
