OBJECTIVE: To study the effect of age on the risk-benefit balance of abatacept in RA. METHODS: Data from the French orencia and RA registry, including a 2-year follow-up, were used to compare the effectiveness and safety of abatacept according to age. RESULTS: Among the 1017 patients, 103 were very elderly (⩾75 years), 215 elderly (65-74), 406 intermediate aged (50-64) and 293 very young (<50). At baseline, elderly and very elderly patients had longer disease duration, higher CRP levels and higher disease activity. These age groups showed a lower incidence of previous anti-TNF therapy and less common concomitant use of DMARDs, but a similar use of corticosteroid therapy. After adjusting for disease duration, RF/ACPA positivity, use of DMARDs or corticosteroids and previous anti-TNF treatment, the EULAR response (good or moderate) and the remission rate were not significantly different between the four age groups. At 6 months, the very elderly had a significantly lower likelihood of a good response than the very young (odds ratio = 0.15, 95% CI: 0.03, 0.68). The decrease in DAS28-ESR over the 24-month follow-up period did not differ by age. Increasing age was associated with a higher rate of discontinuation for adverse events, especially severe infections (per 100 patient-years: 1.73 in very young, 4.65 in intermediates, 5.90 in elderly, 10.38 in very elderly; P < 0.001). CONCLUSION: The effectiveness of abatacept is not affected by age, but the increased rate of side effects, especially infections, in the elderly must be taken into account.

OBJECTIVES: The aim of this paper is to analyse the use of anti-TNF drugs in current Italian practice, evaluate clinical responses to treatment, and identify possible predictors of negative response in patients with rheumatoid arthritis (RA). METHODS: DOSE is a non-interventional, prospective study of patients with active RA treated for the first time with anti-TNF agents in 21 Italian hospitals. Demographic and clinical characteristics of patients, treatments and outcome measures were assessed. Outcome measures used were EULAR response, DAS28 remission and HAQ remission at 12 months. A stepwise logistic regression model was used to study the predictors of non-response. RESULTS: Of 299 RA patients (mean 53.8 ± 12.8 years, 76.1% female), DAS28 was >5.1 in 60.5% of patients and HAQ was >1 in 65.9%. Etanercept was the most prescribed anti-TNF. DMARDs were used in 77.6% of patients (methotrexate in 59.2%). Significant improvements in clinical and laboratory parameters were observed at 12 months. The proportion of patients classed as non-responders remained high, and varied according to assessment criteria. The main predictors independently and significantly associated with a high risk of non-response were: age and female gender for all outcome criteria; high DAS28 value for disease remission; and HAQ >1 for disability remission. CONCLUSIONS: In Italian anti-TNF treatment for RA, age, gender, and high values of both disease activity and disability were predictors of non-response to first-line therapy with anti-TNF drugs. Future studies should consider optimal second-line therapies for RA patients who do not achieve remission to their first anti-TNF treatment.

OBJECTIVE: To assess the safety and efficacy of tocilizumab (TCZ) in elderly (≥65 years) rheumatoid arthritis (RA) patients treated in daily practice. METHODS: We conducted a retrospective study of TCZ use in RA patients in five French university hospitals between 2009 and 2012. We considered two age groups, under 65 years (<65) and over 65 years (≥65). TCZ efficacy was evaluated at 24 weeks by the European League Against Rheumatism (EULAR) response and remission score. We also evaluated drug maintenance and safety, relative to adverse events discontinuation. A multivariate cumulative logit model for ordinal categories was performed to assess the relationship between age class and EULAR response (none, moderate and good) adjusted on possible confounders. TCZ retention (drug survival) over time was estimated with the Kaplan-Meier method. Treatment retention curves were compared according to age group with the log-rank test. RESULTS: Among 222 RA patients treated with TCZ, 61 (27.5%) were≥65 years at the initiation of treatment. After 6 months, this elderly patient group less often reached remission (27.8% versus 45.6%; P=0.02) or good EULAR response (40.7% versus 61.0%; P<0.01) compared to the younger patient group (<65). Multivariate analysis adjusted on baseline C-reactive protein and disease duration confirmed that elderly patients were more likely to have a lower EULAR response (none vs moderate-good or none-moderate vs good) (OR: 3.63; 95% CI [1.86-7.06], P<0.001) compared to younger patients. Drug maintenance for TCZ and adverse events discontinuation rates were similar between the two age groups. CONCLUSION: In daily practice, TCZ seems to be well tolerated in RA patients but is less efficient in elderly patients. A broader field of analysis to include an international register will be required to confirm these results.

OBJECTIVE: Our study aimed to evaluate the longterm efficacy and safety of abatacept (ABA), and to explore factors that increase its longterm efficacy in patients with rheumatoid arthritis (RA) treated in routine clinical practice. METHODS: There were 231 participants with RA treated with ABA who were prospectively registered in a Japanese multicenter registry. They were followed up for at least 52 weeks. RESULTS: Mean age of the patients was 64.3 years, mean disease duration was 12.1 years, mean 28-joint Disease Activity Score (DAS28)-C-reactive protein was 4.49, and 48.5% of patients were concomitantly treated with methotrexate (MTX). Overall retention rate of ABA was 77.1% at 52 weeks; 14.8% of patients discontinued because of inadequate response and 3.5% because of adverse events. The proportion of patients achieving DAS28-defined low disease activity (LDA) significantly increased from baseline to 52 weeks (7.3% to 43.8%, p < 0.01); 40.9% of patients who did not achieve LDA at 24 weeks had more than 1 categorical improvement in DAS28-defined disease activity at 52 weeks. Multivariate logistic regression revealed concomitant MTX use to be an independent predictor of the categorical improvement in DAS28-defined disease activity from 24 to 52 weeks (adjusted OR 3.124, p = 0.010). CONCLUSION: In routine clinical practice, ABA demonstrated satisfactory clinical efficacy and safety in patients with established RA for 52 weeks. The clinical efficacy of ABA increased with time even after 24 weeks, and this was strongly influenced by concomitant MTX use. Our study provides valuable real-world findings on the longterm management of RA with ABA.

OBJECTIVE: Patients with rheumatoid arthritis (RA) are at increased risk for herpes zoster (HZ) (i.e., shingles). The aim of this study was to determine whether treatment with tofacitinib increases the risk of HZ in patients with RA. METHODS: HZ cases were identified as those reported by trial investigators from the databases of the phase II, phase III, and long-term extension (LTE) clinical trials in the Tofacitinib RA Development Program. Crude incidence rates (IRs) of HZ per 100 patient-years (with 95% confidence intervals [95% CIs]) were calculated by exposure group. Logistic regression analyses were performed to evaluate potential risk factors for HZ (e.g., age, prednisone use). RESULTS: Among 4,789 participants, 239 were identified as having tofacitinib-associated HZ during the phase II, phase III, and LTE trials, of whom 208 (87%) were female and whose median age was 57 years (range 21-75 years). One HZ case (0.4%) was multidermatomal; none of the cases involved visceral dissemination or death. Twenty-four patients with HZ (10%) permanently discontinued treatment with tofacitinib, and 16 (7%) were either hospitalized or received intravenous antiviral drugs. The crude HZ IR across the development program was 4.4 per 100 patient-years (95% CI 3.8-4.9), but the IR was substantially higher within Asia (7.7 per 100 patient-years, 95% CI 6.4-9.3). Older age was associated with HZ (odds ratio 1.9, 95% CI 1.5-2.6), and IRs for HZ were similar between patients receiving 5 mg tofacitinib twice daily (4.4 per 100 patient-years, 95% CI 3.2-6.0) and those receiving 10 mg twice daily (4.2 per 100 patient-years, 95% CI 3.1-5.8). In the phase III trials among placebo recipients, the incidence of HZ was 1.5 per 100 patient-years (95% CI 0.5-4.6). CONCLUSION: In the Tofacitinib RA Development Program, increased rates of HZ were observed in patients treated with tofacitinib compared with those receiving placebo, particularly among patients within Asia. Complicated HZ among tofacitinib-treated patients was rare.

BACKGROUND: Controversy exists in understanding the effects of age at onset and comorbidities in predicting rheumatoid arthritis (RA) response to biologic therapy. OBJECTIVE: The objective of this study was to investigate the influence of age at onset and number of comorbidities on Health Assessment Questionnaire-Disability Index (HAQ-DI) and Clinical Disease Activity Index (CDAI) responses in active RA patients after 6 months of treatment with etanercept. METHODS: One thousand eight hundred ninety-nine RA patients were assessed after 6 months of etanercept therapy. Patients met the following inclusion criteria: initiated etanercept, continued therapy for at least 6 months, and were not in CDAI low disease activity (LDA) at baseline (CDAI ≤10.0). Changes in HAQ-DI and CDAI scores over 6 months were analyzed across age of onset quintiles. Multivariate regression models evaluated the independent association between both age at onset and number of comorbidities with change in HAQ-DI/CDAI scores or achieving LDA, while accounting for other covariates. RESULTS: Significant improvements in HAQ-DI and CDAI scores were observed in all age-onset groups, although HAQ-DI improvements were less in older-onset patients. Results of multiple linear regression demonstrated that younger age at onset, higher baseline HAQ-DI/CDAI score, rheumatoid factor positivity, shorter disease duration, and fewer comorbidities at baseline were independently associated with improvement in both HAQ-DI and CDAI scores. Similarly, achieving CDAI LDA after 6 or more months of etanercept was associated with younger age at onset, higher baseline CDAI, shorter disease duration, and fewer comorbidities. CONCLUSIONS: These patients with older-onset RA and more comorbidities clinically improved with etanercept, but had lower odds of achieving CDAI LDA. Age of onset and number of comorbidities may be important in determining RA tumor necrosis factor inhibitor response.

OBJECTIVES: To compare the risk of infection for rheumatoid arthritis (RA) patients who took etanercept or adalimumab medication in a nationwide population. METHODS: RA patients who took etanercept or adalimumab were identified in the Taiwan's National Health Insurance Research Database. The composite outcome of serious infections, including hospitalization for infection, reception of an antimicrobial injection, and tuberculosis were followed for 365 days. A Kaplan-Meier survival curve with a log-rank test and Cox proportional hazards regression were used to compare risks of infection between the two cohorts of tumor necrosis factor (TNF)-α antagonists users. Hazard ratios (HRs) were obtained and adjusted with propensity scores and clinical factors. Sensitivity analyses and subgroup analyses were also performed. RESULTS: In total, 1660 incident etanercept users and 484 incident adalimumab users were eligible for the analysis. The unadjusted HR for infection of the etanercept users was significantly higher than that of the adalimumab users (HR: 1.93; 95% confidence interval (CI): 1.09-3.42; p=0.024). The HRs were 2.04 (95% CI: 1.14-3.65; p=0.016) and 2.02 (95% CI: 1.13-3.61; p=0.018) after adjusting for propensity scores and for propensity scores in addition to clinical factors, respectively. The subgroup analyses revealed that HRs for composite infection was significantly higher in patient subgroups of older age, female, as well as patients who did not have DM, COPD, and hospitalization history at the baseline. CONCLUSION: In this head-to-head cohort study involving a nationwide population of patients with RA, etanercept users demonstrated a higher risk of infection than adalimumab users. Results of this study suggest the possible existence of an intra-class difference in infection risk among TNF-α antagonists.

OBJECTIVE: An all-patient postmarketing surveillance program was conducted to evaluate the safety and effectiveness of tocilizumab (TCZ) for rheumatoid arthritis (RA) in the real-world clinical setting in Japan. METHODS: Patients received 8 mg/kg TCZ every 4 weeks and were observed for 28 weeks. Data were collected on patient characteristics, and drug safety and effectiveness. RESULTS: A total of 7901 patients were enrolled. Percentages of total and serious adverse events (AE) were 43.9% and 9.6%, respectively. The most common serious AE were infections (3.8%). Logistic regression analysis identified the following risk factors for the development of serious infection: age ≥ 65 years, disease duration ≥ 10 years, previous or concurrent respiratory disease, and concomitant corticosteroid dose > 5 mg/day (prednisolone equivalent). The incidence rate of serious infections in patients with ≥ 3 risk factors was 11.2%, compared with 1.2% for patients without risk factors. The Week 28 rates of 28-joint Disease Activity Score-erythrocyte sedimentation rate remission, Boolean remission, and European League Against Rheumatism (EULAR) Good Response were 47.6%, 15.1%, and 59.4%, respectively. Contributing factors for effectiveness were body weight ≥ 40 kg, less advanced RA, no previous biologics, no concomitant corticosteroids or nonsteroidal antiinflammatory drugs, and low disease activity at baseline. From the benefit-risk balance analysis, patients with a high probability of remission and a low probability of developing serious infection were most likely to have less advanced RA and to have not received biologics previously. CONCLUSION: These data confirm the safety and effectiveness of TCZ in patients with RA in the real-world clinical setting in Japan and identify factors that contribute to the successful use of TCZ for RA.

OBJECTIVE: Assessing retention rate and risk factor for drug discontinuation is important for drug evaluation. We examined a 3-year retention rate and the risk factor for discontinuation due to insufficient efficacy (IE) and adverse events (AE) in Japanese patients with rheumatoid arthritis (RA) who are receiving etanercept (ETN). METHODS: Data were collected from 588 patients treated with ETN as a first biologic from the Tsurumai Biologics Communication Registry. Baseline characteristics for the incidence of both IE and AE were analyzed using the Cox proportional-hazards regression model. Patients were divided into groups based on age and concomitant methotrexate (MTX). Drug retention rates were calculated using the Kaplan-Meier method and compared among groups using the log-rank test. RESULTS: ETN monotherapy without concomitant MTX [MTX(-)] was significantly related to a higher incidence of discontinuation due to IE [hazard ratio (HR) = 2.226, 95% CI 1.363-3.634]. Older age and MTX(-) were significantly related to a higher incidence of discontinuation due to AE [HR = 1.040, 1.746, 95% CI 1.020-1.060, 1.103-2.763, respectively]. The MTX(-)/≥ 65 years group had the lowest retention rate (p < 0.001). The discontinuation rate due to IE was lower in the MTX(+)/< 65 years group compared to < 65 years/MTX(-), ≥ 65 years/MTX(-) group (p = 0.006, p < 0.001, respectively). The discontinuation rate due to AE was highest in the MTX(-)/≥ 65 years group (p < 0.001). CONCLUSION: Our findings suggest that the risk of discontinuation due to IE was high in the patients who did not use concomitant MTX and that the risk of discontinuation due to AE was high in elderly patients who did not use concomitant MTX.

OBJECTIVE: The objective of this study was to identify predictors of response and remission to tocilizumab (TCZ) in RA patients seen in daily routine clinical practice. METHODS: The efficacy of TCZ was evaluated after 12 and 24 weeks of treatment by the European League Against Rheumatism (EULAR) response criteria. Regression analysis was performed to study the association between remission or EULAR response and the following characteristics: gender, age, current smokers, prior cardiovascular disease (CVD), 28-joint disease activity score (DAS28), CRP, RF or ACPA positivity, combination therapy with DMARDs and TCZ as the first biological therapy or after failure of at least one biological therapy. RESULTS: In total, 204 patients were included with a mean DAS28 score of 5.14. EULAR response and remission were obtained in 86.1% and 40% of patients, respectively, at week 24. In multiple regression analysis, a high baseline CRP level [odds ratio (OR) 4.454 (95% CI 1.446, 13.726)] was significantly associated with EULAR response at week 24 and, inversely, age >55 years [OR 0.285 (95% CI 0.086, 0.950)] and prior CVD [OR 0.305 (95% CI 0.113, 0.825)] were significantly associated with lower EULAR response at week 24. Older age was also associated with less remission at week 24 [OR 0.948 (95% CI 0.920, 0.978)]. No additional effectiveness was found when TCZ was used in combination with a DMARD or when patients were naive to biological agents. CONCLUSION: In daily practice we identified three predictors of a better response for TCZ therapy in RA: a younger age, a high baseline CRP level and no history of CVD.
