Long-term safety of sarilumab in rheumatoid arthritis: an integrated analysis with up to 7 years' follow-up.

ABSTRACT: OBJECTIVE:Sarilumab is a human monoclonal antibody that blocks IL-6 from binding to membrane-bound and soluble IL-6 receptor-?. We assessed the long-term safety of sarilumab in patients from eight clinical trials and their open-label extensions. METHODS:Data were pooled from patients with rheumatoid arthritis who received at least one dose of sarilumab in combination with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs; combination group) or as monotherapy (monotherapy group). Treatment-emergent adverse events (AEs) and AEs and laboratory values of special interest were assessed. RESULTS:2887 patients received sarilumab in combination with csDMARDs and 471 patients received sarilumab monotherapy, with mean exposure of 2.8 years and 1.7 years, maximum exposure 7.3 and 3.5 years, and cumulative AE observation period of 8188 and 812 patient-years, respectively. Incidence rates per 100 patient-years in the combination and monotherapy groups, respectively, were 9.4 and 6.7 for serious AEs, 3.7 and 1.0 for serious infections, 0.6 and 0.5 for herpes zoster (no cases were disseminated), 0.1 and 0 for gastrointestinal perforations, 0.5 and 0.2 for major adverse cardiovascular events, and 0.7 and 0.6 for malignancy. Absolute neutrophil counts <1000 cells/mm3 were recorded in 13% and 15% of patients, respectively. Neutropenia was not associated with increased risk of infection or serious infection. Analysis by 6-month interval showed no signal for increased rate of any AE over time. CONCLUSION:The long-term safety profile of sarilumab, either in combination with csDMARDs or as monotherapy, remained stable and consistent with the anticipated profile of a molecule that inhibits IL6 signalling.

Project description:ObjectiveTo evaluate the long-term safety and efficacy of sarilumab with/without conventional synthetic (cs)DMARDs in RA.MethodsThe analyses evaluated two open-label extensions (OLEs): EXTEND and MONARCH OLE, which included patients from six randomized trials. Patients received sarilumab 200 mg once every 2 weeks (q2w) for at least 264 weeks up to 516 weeks (EXTEND: Sarilumab Monotherapy and Sarilumab + csDMARD groups) or for 276 weeks (MONARCH OLE: Continuation and Switch groups). Primary endpoints included safety, immunogenicity and changes in laboratory parameters. Secondary endpoints included clinical signs and symptoms along with health-related quality-of-life (HRQOL) questionnaires.ResultsThe Sarilumab Monotherapy (n = 111), Continuation (n = 165) and Switch (n = 155) groups received sarilumab monotherapy, while the Sarilumab + csDMARD group (n = 1910) received sarilumab in combination with csDMARDs. Incidence of one or more treatment-emergent adverse events was 126 (Sarilumab Monotherapy group), 169 (Sarilumab + csDMARD group), 159 (Continuation group) and 159 (Switch group) events/100 patient-years. Neutropenia was the most common adverse event. Neutropenia was not associated with an increased incidence of infections. Most neutropenia cases normalized on-treatment. Adverse events of special interests, such as malignancies, major adverse cardiovascular events, venous thromboembolism and gastrointestinal perforations, were rare. Immunogenicity was low and not associated with hypersensitivity reactions or discontinuations due to lack or loss of efficacy. Improvements in clinical signs and symptoms and HRQOL, observed during the initial blinded trials, were maintained throughout the OLE assessment period.ConclusionsLong-term sarilumab treatment with/without csDMARDs in patients with RA revealed no new safety findings. Efficacy and HRQOL were maintained or further increased over the open-label assessment period.Trial registrationEXTEND, ClinicalTrials.gov, https://www.clinicaltrials.gov/ct2/show/NCT01146652, NCT01146652; MONARCH OLE, ClinicalTrials.gov, https://clinicaltrials.gov/ct2/show/NCT02332590, NCT02332590.

Project description:To investigate the safety of long-term subcutaneous (SC) abatacept treatment using integrated clinical trial data obtained in patients with rheumatoid arthritis refractory to traditional disease-modifying antirheumatic drugs.Data from the double-blind and open-label phases of 5 clinical trials of SC abatacept were pooled. The overall and 6-month incidence rates were calculated as events per 100 patient-years of exposure.This analysis included 1,879 patients with 4,214.6 patient-years of exposure to SC abatacept. The mean ± SD length of exposure was 27.3 ± 9.1 months. The reported incidence rate of serious infections was 1.79 (95% confidence interval [95% CI] 1.42-2.24); the most frequent infections were pneumonia (incidence rate 0.36 [95% CI 0.22-0.59]), urinary tract infection (incidence rate 0.14 [95% CI 0.06-0.32]), and gastroenteritis (incidence rate 0.10 [95% CI 0.04-0.25]). Tuberculosis occurred rarely (incidence rate 0.09 [95% CI 0.04-0.25]). The reported incidence rate of malignancies was 1.32 (95% CI 1.01-1.72), and the most common was solid organ malignancy (incidence rate 0.69 [95% CI 0.48-0.99]). The incidence rate of autoimmune events was 1.37 (95% CI 1.06-1.78), and the most frequent events were psoriasis (incidence rate 0.33 [95% CI 0.20-0.56]) and Sjögren's syndrome (incidence rate 0.24 [95% CI 0.13-0.44]). The reported incidence rate of local injection site reactions was 1.72 (95% CI 1.36-2.17); these events occurred primarily during the first 6 months of treatment, and almost all were of mild or moderate intensity. The incidence rates of serious infections, malignancies, autoimmune events, and injection site reactions did not increase over time.Long-term treatment with SC abatacept was associated with low incidence rates of serious infections, malignancies, and autoimmune events and was well tolerated, with infrequent injection site reactions. These findings are consistent with those related to treatment with intravenous abatacept. Long-term treatment with SC abatacept did not lead to new safety signals over time.

Project description:BackgroundOutcomes after total ankle arthroplasty (TAA) combined with additive techniques (augmentation of bone strength, control of soft-tissue balance, adjustment of the loading axis) for the treatment of rheumatoid arthritis were evaluated after intermediate to long-term follow-up. The influences of biologic treatment on the outcomes after TAA were also evaluated.MethodsWe performed a retrospective observational study involving 50 ankles (44 patients) that underwent TAA for the treatment of rheumatoid arthritis. The mean duration of follow-up was 7.1 years. Clinical outcomes were evaluated with use of the Japanese Society for Surgery of the Foot (JSSF) scale score and a postoperative self-administered foot-evaluation questionnaire (SAFE-Q). Radiographic findings were evaluated as well. These parameters also were compared between patients managed with and without biologic treatment.ResultsThis procedure significantly improved the clinical scores of the JSSF rheumatoid arthritis foot and ankle scale (p < 0.0001). Forty-eight of the 50 ankles had no revision TAA surgery. Subsidence of the talar component was seen in 8 ankles (6 in the biologic treatment group and 2 in the non-biologic treatment group); 2 of these ankles (both in the biologic treatment group) underwent revision TAA. The social functioning score of the SAFE-Q scale at the time of the latest follow-up was significantly higher in the biologic treatment group (p = 0.0079). The dosage of prednisolone (p = 0.0003), rate of usage of prednisolone (p = 0.0001), and disease-activity score (p < 0.01) at the time of the latest follow-up were all significantly lower in the biologic treatment group.ConclusionsTAA is recommended for the treatment of rheumatoid arthritis if disease control, augmentation of bone strength, control of soft-tissue balance, and adjustment of the loading axis are taken into account. The prevention of talar component subsidence remains a challenge in patients with the combination of subtalar fusion, rheumatoid arthritis, and higher social activity levels.Level of evidenceTherapeutic Level III.
