Rheumatologists, take heart! We may be doing something right

In the present issue of Arthritis Research & Therapy data are presented suggesting that antirheumatic therapies decrease the risk of cardiovascular disease in patients with rheumatoid arthritis. The QUEST-RA group, a large international collaboration, analyzed data on 4,363 patients in a cross-sectional manner. Traditional risk factors were all significantly associated with cardiovascular events, and the presence of extraarticular disease significantly increased the risk, confirming a previous publication. The most interesting analysis in this study suggests that effective antirheumatic treatment, with traditional disease-modifying antirheumatic drugs (DMARDs), glucocorticoids, or anti-TNF biologics, reduces the risk of cardiovascular disease in rheumatoid arthritis. Some methodological issues are discussed, however, and confirmatory studies are suggested

Patient Preference Assessment Reveals Disease Aspects Not Covered by Recommended Outcomes in Polymyositis and Dermatomyositis

Objectives. Polymyositis (PM) and dermatomyositis (DM) are characterized by impaired muscle function with a majority of patients developing sustained disability. The aim of this study was to evaluate the patient's individual priorities (patient preference) of disabilities most important to improve in PM/DM using the MacMaster Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR), to correlate the MACTAR to myositis outcomes and to evaluate its test-retest reliability. Methods. Twenty-eight patients with PM/DM performed recommended outcomes as well as the MACTAR, which was performed twice with one week apart. Results. Sexual activity, walking, biking, social activities, and sleep constituted the predominating disabilities. Seventy-two and 33% of the identified disabilities were not covered by items of the Health Assessment Questionnaire and the Myositis Activities Profile. Correlations between the MACTAR and health-related quality of life measures were rs = −0.67–0.73, correlations with measures of activities of daily living and participation in society were rs = 0.51–0.60 with lower correlations for other outcomes. Intraclass correlation (ICC) and weighted Kappa (Kw) coefficients were 0.83 and 0.68, respectively, for test-retest reliability of the MACTAR. Conclusions. The MACTAR interview had promising measurement properties and identified patient preference disabilities in PM/DM that were not covered by recommended outcomes

Efficacy of tofacitinib monotherapy in methotrexate-naive patients with early or established rheumatoid arthritis.

IntroductionTofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). Tofacitinib monotherapy was previously shown to inhibit structural damage, reduce clinical signs and symptoms of RA, and improve physical functioning over 24 months in methotrexate (MTX)-naive adult patients with RA. In this post hoc analysis, we compared efficacy and safety of tofacitinib in patients with early (disease duration <1 year) versus established (≥1 year) RA.MethodsMTX-naive patients ≥18 years with active RA received tofacitinib monotherapy (5 or 10 mg two times a day, or MTX monotherapy, in a 24-month Phase 3 trial.ResultsOf 956 patients (tofacitinib 5 mg two times a day, n=373; tofacitinib 10 mg two times a day, n=397; MTX, n=186), 54% had early RA. Baseline disease activity and functional disability were similar in both groups; radiographic damage was greater in patients with established RA. At month 24, clinical response rates were significantly greater in patients with early versus established RA in the tofacitinib 5 mg two times a day group. Both tofacitinib doses had greater effects on clinical, functional and radiographic improvements at 1 and 2 years compared with MTX, independent of disease duration. No new safety signals were observed.ConclusionsTreatment response was generally similar in early and established RA; significantly greater improvements were observed at month 24 with tofacitinib 5 mg two times a day in early versus established RA. Tofacitinib 5 and 10 mg two times a day demonstrated greater efficacy versus MTX irrespective of disease duration. No difference in safety profiles was observed between patients with early or established RA.Trial registration numberNCT01039688; Results

Etanercept versus etanercept plus methotrexate: a registry-based study suggesting that the combination is clinically more efficacious

Etanercept can be used both as monotherapy and in combination with methotrexate (MTX), but direct comparisons of these two options have not yet been reported. In order to compare the results seen in actual practice between these two options, clinical data on 97 patients followed in the Stockholm TNFα Follow-Up Registry were analysed. In 57 of these patients etanercept was added to previously started MTX while the others were treated with etanercept alone. The two groups had similar levels of disease activity at baseline. After 3 months, a significantly lower mean disease activity score (28-joint count-based disease activity score) was attained by the patients on etanercept plus MTX. In this group, the number of patients achieving European League Against Rheumatism-defined remission was also significantly greater. Other disease outcomes showed non-significant trends in the same direction. These data suggest that the combination of etanercept plus MTX is clinically more efficacious than etanercept alone

Evaluation of hand bone loss by digital X-ray radiogrammetry as a complement to clinical and radiographic assessment in early rheumatoid arthritis: results from the SWEFOT trial

BACKGROUND: To investigate hand bone loss (HBL) measured by digital X-ray radiogrammetry (DXR) in patients with early rheumatoid arthritis (RA) receiving different treatment regimens, and to evaluate if DXR change rates during the first 12 months correlate with radiological damage after 24 months. METHODS: From the total SWEFOT trial population, 159 patients had hand radiographs correctly timed and taken with same modality to be analyzed with DXR. All patients started treatment with methotrexate. After 3–4 months, patients with DAS28 > 3.2 were randomized to add sulfasalazine and hydroxychloroquine (triple therapy) or infliximab (MTX + INF). Those with DAS28 ≤3.2 were followed in regular care. Radiographic progression over 24 months was scored according to the Sharp van der Heijde score (SHS) and defined as >5 increase in T-SHS over 24 months. Hand bone mineral density (BMD) was measured by DXR at inclusion and 12 months and a change ≥2.5 mg/cm(2)/month was used as a cut-off for HBL. RESULTS: In the MTX responders, triple therapy, and MTX + INF groups, the proportions with HBL were 4.1%, 22.2% and 16.4%, respectively (p = 0.01), and the mean (SD) radiological progression in these groups was 3.91 (6.72), 7.40 (14.63) and 2.72 (4.55) respectively (p = 0.06). Patients with HBL had significantly greater risk for radiographic progression, compared with patients without HBL (odds ratio 3.09, 95% CI =1.20–7.79, p = 0.02). CONCLUSIONS: Non-responders to MTX had a significantly greater risk of HBL than MTX-responders, despite the add-on therapies. Patients with HBL during the 12 months had greater risk of radiographic progression after 24 months. Evaluation of HBL may help to identify patients who are at risk of radiographic progression

Tocilizumab in early progressive rheumatoid arthritis: FUNCTION, a randomised controlled trial

OBJECTIVES: The efficacy of tocilizumab (TCZ), an anti-interleukin-6 receptor antibody, has not previously been evaluated in a population consisting exclusively of patients with early rheumatoid arthritis (RA). METHODS: In a double-blind randomised controlled trial (FUNCTION), 1162 methotrexate (MTX)-naive patients with early progressive RA were randomly assigned (1:1:1:1) to one of four treatment groups: 4 mg/kg TCZ+MTX, 8 mg/kg TCZ+MTX, 8 mg/kg TCZ+placebo and placebo+MTX (comparator group). The primary outcome was remission according to Disease Activity Score using 28 joints (DAS28-erythrocyte sedimentation rate (ESR) \u3c 2.6) at week 24. Radiographic and physical function outcomes were also evaluated. We report results through week 52. RESULTS: The intent-to-treat population included 1157 patients. Significantly more patients receiving 8 mg/kg TCZ+MTX and 8 mg/kg TCZ+placebo than receiving placebo+MTX achieved DAS28-ESR remission at week 24 (45% and 39% vs 15%; p \u3c 0.0001). The 8 mg/kg TCZ+MTX group also achieved significantly greater improvement in radiographic disease progression and physical function at week 52 than did patients treated with placebo+MTX (mean change from baseline in van der Heijde-modified total Sharp score, 0.08 vs 1.14 (p=0.0001); mean reduction in Health Assessment Disability Index, -0.81 vs -0.64 (p=0.0024)). In addition, the 8 mg/kg TCZ+placebo and 4 mg/kg TCZ+MTX groups demonstrated clinical efficacy that was at least as effective as MTX for these key secondary endpoints. Serious adverse events were similar among treatment groups. Adverse events resulting in premature withdrawal occurred in 20% of patients in the 8 mg/kg TCZ+MTX group. CONCLUSIONS: TCZ is effective in combination with MTX and as monotherapy for the treatment of patients with early RA. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, number NCT01007435

Long-term maintenance of certolizumab pegol safety and efficacy, in combination with methotrexate and as monotherapy, in rheumatoid arthritis patients

Introduction The safety and efficacy of certolizumab pegol (CZP) 400 mg every 4 weeks (Q4W) monotherapy (FAST4WARD/NCT00548834) and in combination with methotrexate (MTX) (014/NCT00544154) in active rheumatoid arthritis (RA) has been published previously. This report outlines final long-term outcomes from the open-label extension (OLE) study (015/NCT00160693), which enrolled patients from these randomized controlled trials (RCTs). Methods Patients who withdrew from or completed the 24-week 014/FAST4WARD RCTs were enrolled and received CZP 400 mg Q4W with/without MTX. Exposure-adjusted event rates (ER) per 100 patient-years (PYs) of adverse events (AEs) and serious AEs (SAEs) were reported for all patients receiving ≥1 dose of CZP in RCTs or OLE (N = 427) between first CZP dose and up to 24 weeks after last CZP dose or study withdrawal. Efficacy assessments included clinical (ACR20/50/70 response rates, TJC, SJC) and patient-reported outcomes (HAQ-DI, PtGADA, pain, fatigue) to week 304 (5.8 years) in the CZP intent-to-treat population. SDAI and CDAI outcomes were analyzed post hoc. Outcomes for CZP monotherapy and CZP+MTX combination-therapy were compared. Results Globally, ERs of AEs and SAEs were 408.1 and 25.2 per 100 PY, respectively. Eleven patients had AEs leading to death (ER 0.6). Improvements in clinical and patient-reported outcomes during the 24-week RCTs were maintained to week 304, and were similar between all subpopulations. Conclusions The longest exposure duration to date with CZP 400 mg Q4W treatment confirmed the safety profile observed in previous studies. Initial improvements in signs and symptoms of RA, including PROs, were maintained in both CZP monotherapy and CZP + MTX combination-therapy patients

Safety of Repeated Open-Label Treatment Courses of Intravenous Ofatumumab, a Human Anti-CD20 Monoclonal Antibody, in Rheumatoid Arthritis:Results from Three Clinical Trials

OBJECTIVES:To investigate the safety of ofatumumab retreatment in rheumatoid arthritis. METHODS:Patients with active rheumatoid arthritis participating in two phase III trials (OFA110635 and OFA110634) and a phase II extension trial (OFA111752) received individualised open-label ofatumumab retreatment (700 mg X 2 intravenous infusions two weeks apart) ≥24 weeks following the first course and ≥16 weeks following further courses. Retreatment required evidence of clinical response followed by disease relapse. These studies were prematurely terminated by the sponsor to refocus development on subcutaneous delivery. Due to differences in study designs and populations, data are summarised separately for each study. RESULTS:483 patients (243, 148 and 92 in OFA110635, OFA110634 and OFA111752 respectively) received up to 7 treatment courses of intravenous ofatumumab; cumulative duration of exposure was 463, 182 and 175 patient-years, respectively. Mean time between courses was 17-47 weeks. Ofatumumab induced a profound depletion of peripheral B-lymphocytes. Retreated patients derived benefit based on improvement in DAS28. Adverse events were reported for 93% (226/243), 91% (134/148) and 76% (70/92), serious adverse events for 18% (44/243), 20% (30/148) and 12% (11/92) and serious infections for 3% (8/243), 5% (7/148) and 1% (1/92) of patients in OFA110635, OFA110634 and OFA111752, respectively. The most common adverse events were infusion-related reactions during the first infusion of the first course (48-79%); serious infusion-related reactions were rare (<1% [1/243], 5% [8/148], and 1% [1/92] of patients). Two deaths occurred (fulminant hepatitis B virus infection and interstitial lung disease). CONCLUSIONS:Ofatumumab was generally well tolerated with no evidence of increased safety risks with multiple retreatments. Serious infections were uncommon and did not increase over time.
