Background: Patients who have had inadequate response to tumour necrosis factor inhibitors have fewer treatment options and are generally more treatment refractory to subsequent therapeutic interventions than previously untreated patients. We report the efficacy and safety of ixekizumab, a monoclonal antibody that selectively targets interleukin-17A, in patients with active psoriatic arthritis and previous inadequate response to tumour necrosis factor inhibitors., Methods: In this double-blind, multicentre, randomised, placebo-controlled, phase 3 study (SPIRIT-P2), patients were recruited from 109 centres across ten countries in Asia, Australia, Europe, and North America. Patients were aged 18 years or older, had a confirmed diagnosis of psoriatic arthritis for at least 6 months, and had a previous inadequate response, distinguished by being refractory to therapy or had loss of efficacy, or were intolerant to tumour necrosis factor inhibitors. Patients were randomly assigned (1:1:1) by a computer-generated random sequence to receive a subcutaneous injection of 80 mg ixekizumab every 4 weeks or every 2 weeks after a 160 mg starting dose or placebo. The primary endpoint was the proportion of patients who attained at least 20% improvement in the American College of Rheumatology response criteria (ACR-20) at week 24. This study is registered with ClinicalTrials.gov, number NCT02349295., Findings: Between March 3, 2015, to March 22, 2016, 363 patients were randomly assigned to placebo (n=118), ixekizumab every 4 weeks (n=122), or ixekizumab every 2 weeks (n=123). At week 24, a higher proportion of patients attained ACR-20 with ixekizumab every 4 weeks (65 [53%] patients; effect size vs placebo 33·8% [95% CI 22·4-45·2]; p<0·0001) and ixekizumab every 2 weeks (59 [48%] patients; 28.5% [17·1-39.8]; p<0·0001) than did patients with placebo (23 [20%] patients). Up to week 24, serious adverse events were reported in three (3%) patients with ixekizumab every 4 weeks, eight (7%) with ixekizumab every 2 weeks, and four (3%) with placebo; no deaths were reported. Infections were reported in 47 (39%) patients with ixekizumab every 4 weeks, 47 (38%) with ixekizumab every 2 weeks, and 35 (30%) with placebo. Three (2%) serious infections, all in patients in the ixekizumab every 2 weeks group, were reported., Interpretation: Both the 2-week and 4-week ixekizumab dosing regimens improved the signs and symptoms of patients with active psoriatic arthritis and who had previously inadequate response to tumour necrosis factor inhibitors, with a safety profile consistent with previous studies investigating ixekizumab., Funding: Eli Lilly and Company., (Copyright © 2017 Elsevier Ltd.

Background: Subclinical myocardial involvement is common in systemic sclerosis (SSc) and associated with poor prognosis. Early detection, particularly during follow-up, is important. Two-dimensional speckle tracking echocardiography (STE) has already been shown to detect early left ventricular systolic impairment in SSc patients with advanced disease. The aim of this study was to assess the ability of STE to diagnose changes in left ventricular function in patients with SSc with preserved LV ejection fraction (LVEF) and normal pulmonary pressure over time., Methods: This single-center pilot study included nineteen SSc patients without pulmonary hypertension and preserved LVEF (55.2 ± 10.8 years, 13 women, mean modified Rodnan Skin Score of 8.2 ± 6.5, median disease duration 6 ± 4.5 years). We performed STE at baseline and after two years (mean 756.6 ± 8.8 days). Pulmonary hypertension was ruled out in all patients by right heart catheterization (average mean PAP 17.7 ± 3.5 mmHg)., Results: The LVEF remained unchanged (63.3 ± 4.2% vs. 63.2 ± 5.0%, P = ns), but the global longitudinal peak systolic strain of the left ventricle was significantly lower: baseline -22.0 ± 2.3% vs. follow-up -20.8 ± 2.1% (P = 0.04). The regional analysis showed a heterogeneous distribution of segmental systolic dysfunction that did not match any particular coronary artery distribution. In contrast, the LV diastolic function remained stable during follow-up., Conclusion: STE might be a sensititive and valuable method to detect early LV systolic impairment in patients with SSc and preserved LVEF during two years. Prospective evaluations are needed for prognostic implications of these changes.

Introduction: We used the data of the German biologics register RABBIT, a nationwide prospective cohort study, to investigate the risk of new or recurrent malignancy in patients with rheumatoid arthritis (RA) receiving biologics compared to conventional disease modifying anti-rheumatic drugs (DMARDs)., Methods: The analysis was based on patients with RA enrolled in RABBIT at the start of a biologic or conventional DMARD therapy between 01 May 2001 and 31 December 2006. Incidences of first or recurrent malignancies were analysed separately. A nested case-control design was used to investigate the risk of developing a first malignancy. Matching criteria were: age, gender, follow-up time, disease activity score based on 28 joint counts (DAS28) at study entry, smoking status, and selected chronic co-morbid conditions (obstructive or other lung disease, kidney, liver or gastrointestinal disease, psoriasis)., Results: A prior malignancy was reported in 122 out of 5,120 patients. Fifty-eight of these patients had received anti-TNFalpha agents, 9 anakinra, and 55 conventional DMARDs at study entry. In 14 patients (ever exposed to anti-TNFalpha: eight, to anakinra: one) 15 recurrent cancers were observed. The average time period since the onset of the first malignancy was nine years. Crude recurrence rates per 1,000 patient-years (pyrs) were 45.5 for patients exposed to anti-TNFalpha agents, 32.3 for anakinra patients and 31.4 for patients exposed to DMARDs only (Incidence rate ratio anti-TNFalpha vs. DMARD = 1.4, P = 0.6.). In patients without prior cancer, 74 patients (70% female, mean age: 61.3) developed a first malignancy during the observation. This corresponds to an incidence rate (IR) of 6.0/1,000 pyrs. Forty-four of these patients were ever exposed to anti-TNFalpha treatment (IR = 5.1/1,000 pyrs). In a nested case-control study comparing cancer patients to cancer-free controls, 44 of the cancer patients and 44 of the cancer-free controls were ever exposed to anti-TNFalpha agents (P = 1.0)., Conclusions: No significant differences in the overall incidence of malignancies in patients exposed or unexposed to anti-TNFalpha or anakinra treatment were found. The same applied to the risk of recurrent malignancies. However, in particular this last finding needs further validation in larger data sets.
