Persistence and Adherence during the First Six Months of Tocilizumab Treatment Among Rheumatoid Arthritis Patients in Routine Clinical Practice in Greece. Results from the Single Arm REMISSION II Study (NCT01649817). Mediterr J Rheumatol 2019; 30:177-185. [PMID: 32185362 PMCID: PMC7045860 DOI: 10.31138/mjr.30.3.177] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Revised: 09/19/2019] [Accepted: 09/24/2019] [Indexed: 12/23/2022] Open
Abstract
OBJECTIVE/AIM One of the most important factors that affect a treatment's performance in rheumatoid arthritis (RA) is adherence to medications. According to literature, there are several reasons for non-adherence in RA patients with some of them being related to a specific patient profile of the study population. In this study, we investigated persistence to intravenous tocilizumab (TCZ) therapy in RA during routine clinical practice in Greece and identified causes for non-adherence. METHODS 183 RA patients who mostly attended private practice Rheumatologists and received intravenous TCZ treatment at a schedule of 1 infusion per 4-weeks in the first 6 months were recorded retrospectively. RESULTS Persistence estimated rate to TCZ therapy was 92.0% for patients that received 6 infusions and 83.4% for patients that received 7 infusions of TCZ. Potential factors that influence persistence to therapy were the occurrence of adverse events and response to the therapy. The main reasons for non-adherence to TCZ therapy were non-medically related with the most common being drug supply issues. The 6-month mean change from baseline in DAS28-ESR after initiation of TCZ therapy was -1.3, and the mean CDAI dropped from 29.6 at baseline to 16.7 at 6 months. Good/Moderate response was achieved by 89.1% of patients and remission by 23.5%. The safety profile was similar to that observed in other TCZ trials with the most common being infections, hematologic manifestations and musculoskeletal disorders. CONCLUSION Overall, persistence to therapy appeared to be high in the rheumatology private practice setting and non-adherence to the TCZ treatment schedule is attributed mainly to non-medical reasons.

Abstract
OBJECTIVE To evaluate the tolerability, effectiveness and utilization of tocilizumab for the treatment of RA in a usual care setting. METHODS ROUTINE was a prospective, non-interventional, observational 52-week study performed at 174 sites throughout Germany. RA patients were selected and treated according to label. Study objectives included the targeted documentation of infections, other adverse events, and various effectiveness outcomes (e.g. DAS28, clinical disease activity). Statistical analyses were performed primarily based on the data as observed. RESULTS A total of 850 patients (75% women, mean age: 56 ± 13 years, mean RA duration: 10.3 ± 8.6 years) were enrolled. Most patients (79%) were pretreated with TNF-inhibitors, whereas 21% were pretreated with conventional DMARDs only. Most common DMARD pretreatments were MTX (79%), LEF (68%), adalimumab (53%) and etanercept (50%). At baseline, 60.5% of patients received tocilizumab in combination with any other RA drugs, while 39.5% were treated in monotherapy. Mean baseline DAS28 was 5.5 ± 1.3, and this decreased to 2.6 ± 1.6 at week 52. At week 52, good EULAR response was achieved in 62.3%, low disease activity state in 66.4%, and DAS28 remission in 55.1% of patients (adjusted relative frequencies). 35.3% of patients discontinued the study prematurely; common reasons were lack of effectiveness (10.5%) and intolerability (7.3%). Any infections and severe infections occurred in 37.6% and 7.2% of patients, respectively (N = 836); serious infections were seen in 5.3% (N = 850). Event rates of any, severe and serious infections were 70.3, 9.8 and 4.4 events/100 patient-years, respectively. CONCLUSION Tocilizumab administered in a real-life setting showed clinically meaningful improvements and a safety profile that was consistent with data reported from pre-approval Phase III studies.

Abstract
OBJECTIVE To establish recommendations for the management of patients with rheumatoid arthritis (RA) to serve as a reference for all health professionals involved in the care of these patients, and focusing on the role of available synthetic and biologic disease-modifying antirheumatic drugs (DMARDs). METHODS Consensual recommendations were agreed on by a panel of 14 experts selected by the Spanish Society of Rheumatology (SER). The available scientific evidence was collected by updating three systematic reviews (SR) used for the EULAR 2013 recommendations. A new SR was added to answer an additional question. The literature review of the scientific evidence was made by the SER reviewer's group. The level of evidence and the degree of recommendation was classified according to the Oxford Centre for Evidence-Based Medicine system. A Delphi panel was used to evaluate the level of agreement between panellists (strength of recommendation). RESULTS Thirteen recommendations for the management of adult RA were emitted. The therapeutic objective should be to treat patients in the early phases of the disease with the aim of achieving clinical remission, with methotrexate playing a central role in the therapeutic strategy of RA as the reference synthetic DMARD. Indications for biologic DMARDs were updated and the concept of the optimization of biologicals was introduced. CONCLUSIONS We present the fifth update of the SER recommendations for the management of RA with synthetic and biologic DMARDs.

Abstract
Glucocorticosteroids (GCs) have been employed extensively for the treatment of rheumatoid arthritis (RA) and other autoimmune and systemic inflammatory disorders. Their use is supported by extensive literature and their utility is reflected in their incorporation into current treatment guidelines for RA and other conditions. Nevertheless, there is still some concern regarding the long-term use of GCs because of their potential for clinically important adverse events, particularly with an extended duration of treatment and the use of high doses. This article systematically reviews the efficacy for radiological and clinical outcomes for low-dose GCs (defined as ≤10 mg/day prednisone equivalent) in the treatment of RA. Results reviewed indicated that low-dose GCs, usually administered in combination with synthetic DMARDs, most often MTX, significantly improve structural outcomes and decrease symptom severity in patients with RA. Safety data indicate that GC-associated adverse events are dose related, but still occur in patients receiving low doses of these agents. Concerns about side effects associated with GCs have prompted the development of new strategies aimed at improving safety without compromising efficacy. These include altering the structure of existing GCs and the development of delayed-release GC formulations so that drug delivery is timed to match greatest symptom severity. Optimal use of low-dose GCs has the potential to improve long-term outcomes for patients with RA.

Abstract
OBJECTIVE To determine the prevalence and persistence of new-onset clinical remission in rheumatoid arthritis (RA) patients. METHODS The Consortium of Rheumatology Researchers of North America (CORRONA) cohort was used to examine the prevalence of remission and associated comorbidities and RA therapies according to the 2011 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) remission criteria. Factors influencing the likelihood of remaining in remission were identified by logistic regression with generalized estimating equations. Analysis of variance and Tukey's test were used to determine differences in disability according to whether RA patients had been in remission or only low disease activity (LDA). RESULTS A total of 2105 individuals met ACR/EULAR remission criteria at the most recent visit within CORRONA, yielding an 8% point prevalence of remission. Patients with certain comorbidities (e.g., heart failure) were significantly less likely to achieve or remain in remission compared to those without these conditions (p < 0.001 for each). Among prednisone users, the prevalence of remission was 1-6% (depending on dose) higher compared to those not on prednisone (10%). More than 50% of patients who had consistently been in remission for ≥1 year were able to remain in remission over the next year. Patients consistently in remission had less disability than patients who achieved LDA or who fluctuated between remission and LDA. CONCLUSION Patients consistently in remission for at least 1 year had a high likelihood to remain in remission. These individuals might be considered the most likely candidates for de-escalation or withdrawal of RA treatments.

Abstract
OBJECTIVES: This study aimed to evaluate the remission in rheumatoid arthritis (RA) patients treated with tocilizumab (TCZ), based on prospectively registered data in clinical practice. METHODS: We studied 114 consecutive RA patients treated with TCZ for an average of 3.5 years. Remission was evaluated by using the EULAR criteria and the new ACR/EULAR Boolean-based criteria. RESULTS: Among 114 patients (average age 52.2 years; average disease duration 10.6 years), 76 (67 %) had previously received anti-TNF biologics. Mean baseline DAS28-ESR of 5.4 and improved to 2.4 at 36 months. Overall, DAS28-ESR <2.6 was attained by 66.7 %, while ACR/EULAR remission was attained by 35.1 %. ACR/EULAR remission rate was significantly higher in the patients who were biologics-naïve and had good response at the first month. Among 23 patients who completed the treatment for 3 years and had ACR/EULAR remission at 1 year, 15 (65 %) remained in the remission and 16 (70 %) had a DAS28-ESR <2.6 at the final follow-up. The retention rate at 36 months was 68.2 %. CONCLUSIONS: In patients with RA, TCZ is highly effective for both biologics-naïve patients and patients previously exposed to biologics, achieving a high remission rate and drug continuation rate (68.2 %) in clinical practice.

Abstract
OBJECTIVE To analyze the efficacy of tocilizumab (TCZ) and the factors that influence achievement of Boolean-based remission in patients with rheumatoid arthritis (RA) treated with TCZ in daily clinical practice. METHODS The efficacy of TCZ at 24 weeks after initiation of TCZ in 80 patients with RA was analyzed by comparing achievement of "DAS28 remission" with that of "Boolean-based remission". The predictive factors that influence achievement of Boolean-based remission were determined using multiple logistic regression analysis using a step-wise method. RESULTS DAS28 remission and Boolean-based remission were achieved in 50.0 and 12.5% of patients, respectively. Significant differences in achieving Boolean-based remission were observed when patients were stratified by disease duration in tertiles (p < 0.05) and by physical function in tertiles (p < 0.05); no such differences were observed for achieving DAS28 remission. The least achievable component among the Boolean-based remission criteria was patient's global assessment. The predictive factor for not achieving Boolean-based remission at 24 weeks was having a worse baseline physical function (odds ratio, 3.66; 95 % confidence interval, 1.17-14.48). CONCLUSIONS This study suggests that baseline disability predicts a lack of achievement of Boolean-based remission. Thus, better responses to TCZ may be obtained when TCZ is initiated in RA patients before disability develops.

Abstract
OBJECTIVE We analyzed whether a patient self-report remission criterion, such as that according to the Rheumatoid Arthritis Disease Activity Index-5 (RADAI-5), meets the criteria of the 2011 proposed American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) definition of remission. METHODS The 2 approaches of the ACR/EULAR proposal [Boolean- and Simplified Disease Activity Index (SDAI)-based] as well as the RADAI-5 were used to assess whether patients with RA are in remission. Sensitivity, specificity, positive and negative predictive values (PPV, NPV), and kappa analyses were performed to illustrate the relationship among the different approaches defining remission at a group level. RESULTS In total, 705 patients' assessments were included. Eighty-nine patients were classified as being in remission according to the Boolean-based and 169 according to the SDAI-based definition of the ACR/EULAR proposals, and 154 according to the RADAI-5. Sixty-eight assessments were classified as being in remission according to all 3 definitions. In the case of RADAI-5 remission, sensitivity was 78%, specificity 86%, PPV 45%, and NPV 96%, indicating remission according to the Boolean-based definition; and 60%, 92%, 66%, and 90%, respectively, indicating remission according to the SDAI-based definition. In the case of remission according to the SDAI-based ACR/EULAR definition, sensitivity was 52%, specificity 100%, PPV 98%, and NPV 87%, also indicating remission according to the Boolean definition; while according to the Boolean definition the values were 98%, 87%, 52%, and 100%, respectively. Kappa statistics showed fair to good agreement for all 3 definitions. CONCLUSION Nearly twice as many assessments were classified as being in remission using the SDAI-based or the RADAI-5 definitions when compared to the Boolean-based definition. Remission according to the RADAI-5 also was highly specific for both ACR/EULAR criteria. Sensitivity for the RADAI-5 criterion was even better for the Boolean-based definition than that for the SDAI-based definition.

Abstract
OBJECTIVE To identify if rheumatoid factor (RF) is predictor of response to rituximab (RTX), abatacept (ABT), and tocilizumab (TCZ) in rheumatoid arthritis (RA). METHODS Systematic review and meta-analysis of clinical trials and observational studies based on a sensitive search. Meta-regression was used to explore causes of heterogeneity. Unpublished data of clinical trials provided by the authors were also included. RESULTS The electronic search captured 3221 references and 422 meeting abstracts. By hand search, four additional articles were also identified. A total of 23 studies meet the purpose of the study and were included in the review. RF positivity at starting predicts better ACR20 [OR, 1.95 (1.24, 3.08)], ACR50 [OR, 5.38 (2.50, 11.60)] and EULAR response [OR, 3.52 (1.66, 7.45)] in 14 studies with RTX, and better ACR20 [OR, 1.51 (1.21, 1.90)] in 6 studies with TCZ. In 3 studies with ABT, no association was found between response and RF [OR 1.36 (0.97, 1.90)]. No asymmetries in the funnel plots or significant variables were found in the meta-regression. CONCLUSION In RA, RF positivity predicts better response to RTX and TCZ but not to ABT.

Abstract
Chronic low-grade inflammation, in particular increased concentrations of proinflammatory cytokines such as interleukin (IL)-6 in the circulation, is observed with increasing age, but it is also as a consequence of various medical and psychological conditions, as well as life-style choices. Since molecules such as IL-6 have pleiotropic effects, consequences are wide ranging. This short review summarizes the evidence showing how IL-6 elevations in the context of inflammatory disease affect the organism, with a focus on sleep-related symptoms and fatigue; and conversely, how alterations in sleep duration and quality stimulate increased concentrations of IL-6 in the circulation. Research showing that acute as well as chronic psychological stress also increase concentrations of IL-6 supports the notion of a close link between an organism's response to physiological and psychological perturbations. The findings summarized here further underscore the particular importance of IL-6 as a messenger molecule that connects peripheral regulatory processes with the CNS.

Abstract
To seek the cutoff value of the 28-joint disease activity score using erythrocyte sedimentation rate (DAS28-ESR) that is necessary to achieve remission under the new Boolean-based criteria, we analyzed the data for 285 patients with rheumatoid arthritis registered between May 2008 and November 2009 by the Michinoku Tocilizumab Study Group and observed for 1 year after receiving tocilizumab (TCZ) in real clinical practice. Remission rates under the DAS28-ESR criteria and the Boolean criteria were assessed every 6 months after the first TCZ dose. The DAS28-ESR cutoff value necessary to achieve remission under the new criteria was analyzed by receiver operating characteristic (ROC) analysis. Data were analyzed using last observation carried forward. After 12 months of TCZ use, remission was achieved in 164 patients (57.5 %) by DAS28-ESR and 71 patients (24.9 %) under the new criteria for clinical trials. CRP levels scarcely affected remission rates, and the difference between remission rates defined by DAS28-ESR and by the new criteria was mainly due to patient global assessment (PGA). Improvement of PGA was inversely related to disease duration. ROC analysis revealed that the DAS28-ESR cutoff value necessary to predict remission under the new criteria for clinical trials was 1.54, with a sensitivity of 88.7 %, specificity of 85.5 %, positive predictive value of 67.0 %, and negative predictive value of 95.8 %. A DAS28-ESR cutoff value of 1.54 may be reasonable to predict achievement of remission under the new Boolean-based criteria for clinical trials in patients receiving TCZ.

Abstract
Although treat-to-target goals for rheumatoid arthritis (RA) have been well-established through several guidelines in recent years, concerns regarding treat-to-prevent goals for RA remain unclear. RA patients are typically subjected to over- or under-treatment because it is difficult for clinicians to determine the prognosis of RA patients. This typically results in failure to select and identify patient subsets that should receive monotherapy or combination therapy to treat early RA. Understanding treat-to-prevent goals, as well as unfavorable prognoses, risk factors, and prediction methods for RA, is therefore critical for making treatment decisions. Rapid radiographic progression plays a central role in contributing to other composite RA indices, so this may be the best method for defining treat-to-prevent goals for RA. Accordingly, risk factors of rapid radiographic progression have been defined and two prediction models were retrospectively derived based on clinical trial data. Additional studies are required to develop risk models that can be used for accurate predictions.

A review of tocilizumab treatment in 122 rheumatoid arthritis patients included in the Tsurumai Biologics Communication Registry (TBCR) Study. Mod Rheumatol 2012; 23:245-53.

Abstract
OBJECTIVES Biologics have transformed the treatment of rheumatoid arthritis. Clinical remission is now the goal. We sought to verify whether the administration of tocilizumab-a biologic-can help to achieve current treatment goals. METHODS Using data from the Tsurumai Biologics Communication Registry for 122 patients treated with tocilizumab, we evaluated changes in DAS28-ESR at 12 months after initiation, and also evaluated remission rates defined using conventional and new Boolean-based remission criteria. We divided 50 patients who had received tocilizumab as a first-line treatment into two groups [disease duration at baseline of 12 months or less (≤12 M) and more than 12 months (>12 M)]. RESULTS At 12 months after initiation, there was no difference in DAS28-ESR, and remission rates based on the conventional criterion were also comparable (50 % in both groups). However, under the new criterion, remission was 50.0 % in the ≤12 M group against 12.5 % in the >12 M group (p = 0.0181). Among the individual components of the new remission criterion, the small proportion of patients in the >12 M group with a patient global assessment (PtGA) of ≤1 had a particularly strong influence on the remission rate for that group, but this component was not as important for the ≤12 M group. CONCLUSIONS When used as a first-line biological drug for patients with early-stage RA (≤12 M), tocilizumab appears to provide high rates of remission under the Boolean-based remission criterion, which were strongly affected by the PtGA.

Abstract
Because of the pathological role of IL-6 in rheumatoid arthritis (RA), tocilizumab (TCZ), a humanized anti-IL-6 receptor monoclonal antibody, was expected to improve inflammation and joint destruction of RA. Indeed, randomized clinical trials demonstrated the clinical efficacy of TCZ as monotherapy or combined with methotrexate (MTX) for RA patients with inadequate responses to disease-modifying antirheumatic drugs, MTX or tumor necrosis factor (TNF) inhibitors. Although long-term tolerability for TCZ is superior to that for TNF inhibitors, information regarding the potency of drug free remission of TCZ is limited at present. In terms of its safety profile, the general risk of infection when using TCZ is comparable to that of TNF inhibitors. TCZ has some advantage in RA patients who can not use MTX and are non-responders to TNF inhibitors. In conclusion, TCZ is one of the most prospective next generation biologics for the treatment of RA.

Tocilizumab for the treatment of rheumatoid arthritis and other systemic autoimmune diseases: current perspectives and future directions. Int J Rheumatol 2012; 2012:946048.

Abstract
Interleukin (IL)-6 is a cytokine featuring redundancy and pleiotropic activity. While IL-6, when transiently produced, contributes to host defense against acute environmental stress, continuous dysregulated IL-6 production plays a significant pathological role in several systemic autoimmune diseases. In response to the expectation that IL-6 blockade would constitute a novel therapeutic strategy for the treatment of these diseases, tocilizumab, a humanized anti-IL-6 receptor antibody, was developed. Clinical trials have verified the efficacy and the safety of tocilizumab for patients with rheumatoid arthritis, resulting in approval of this innovative biologic for the treatment of rheumatoid arthritis in more than 90 countries worldwide. Pathological analyses of the effect of IL-6 on the development of autoimmune diseases and a considerable number of case reports and pilot studies have also indicated the beneficial effects of this antibody on other systemic autoimmune diseases, including systemic lupus erythematosus, systemic sclerosis, polymyositis, and large-vessel vasculitis.
