ObjectivesTo compare efficacy and safety of sarilumab monotherapy with adalimumab monotherapy in patients with active rheumatoid arthritis (RA) who should not continue treatment with methotrexate (MTX) due to intolerance or inadequate response.MethodsMONARCH was a randomised, active-controlled, double-blind, double-dummy, phase III superiority trial. Patients received sarilumab (200 mg every 2 weeks (q2w)) or adalimumab (40 mg q2w) monotherapy for 24 weeks. The primary end point was change from baseline in 28-joint disease activity score using erythrocyte sedimentation rate (DAS28-ESR) at week 24.ResultsSarilumab was superior to adalimumab in the primary end point of change from baseline in DAS28-ESR (−3.28 vs −2.20; p<0.0001). Sarilumab-treated patients achieved significantly higher American College of Rheumatology 20/50/70 response rates (sarilumab: 71.7%/45.7%/23.4%; adalimumab: 58.4%/29.7%/11.9%; all p≤0.0074) and had significantly greater improvement in Health Assessment Questionnaire-Disability Index (p=0.0037). Importantly, at week 24, more patients receiving sarilumab compared with adalimumab achieved Clinical Disease Activity Index remission (7.1% vs 2.7%; nominal p=0.0468) and low disease activity (41.8% vs 24.9%; nominal p=0.0005, supplemental analysis). Adverse events occurred in 63.6% (adalimumab) and 64.1% (sarilumab) of patients, the most common being neutropenia and injection site reactions (sarilumab) and headache and worsening RA (adalimumab). Incidences of infections (sarilumab: 28.8%; adalimumab: 27.7%) and serious infections (1.1%, both groups) were similar, despite neutropenia differences.ConclusionsSarilumab monotherapy demonstrated superiority to adalimumab monotherapy by improving the signs and symptoms and physical functions in patients with RA who were unable to continue MTX treatment. The safety profiles of both therapies were consistent with anticipated class effects.Trial registration numberNCT02332590.
Effects on time to failure were comparable between teriflunomide and IFNβ-1a. There was no difference between teriflunomide 14 mg and IFNβ-1a on ARR, though ARR was higher with teriflunomide 7 mg. The teriflunomide safety profile was consistent with previous studies.
ObjectiveTo evaluate the efficacy and safety of sarilumab plus conventional synthetic disease‐modifying antirheumatic drugs (DMARDs) in patients with active moderate‐to‐severe rheumatoid arthritis (RA) who had an inadequate response or intolerance to anti–tumor necrosis factor (anti‐TNF) therapy.MethodsPatients were randomly allocated to receive sarilumab 150 mg, sarilumab 200 mg, or placebo every 2 weeks for 24 weeks with background conventional synthetic DMARDs. The co‐primary end points were the proportion of patients achieving a response according to the American College of Rheumatology 20% criteria for improvement (ACR20) at week 24, and change from baseline in the Health Assessment Questionnaire disability index (HAQ DI) at week 12. Each sarilumab dose was evaluated against placebo; differences between the 2 sarilumab doses were not assessed.ResultsThe baseline characteristics of the treatment groups were similar. The ACR20 response rate at week 24 was significantly higher with sarilumab 150 mg and sarilumab 200 mg every 2 weeks compared with placebo (55.8%, 60.9%, and 33.7%, respectively; P < 0.0001). The mean change from baseline in the HAQ DI score at week 12 was significantly greater for sarilumab (least squares mean change: for 150 mg, −0.46 [P = 0.0007]; for 200 mg, −0.47 [P = 0.0004]) versus placebo (−0.26). Infections were the most frequently reported treatment‐emergent adverse events. Serious infections occurred in 1.1%, 0.6%, and 1.1% of patients receiving placebo, sarilumab 150 mg, and sarilumab 200 mg, respectively. Laboratory abnormalities included decreased absolute neutrophil count and increased transaminase levels in both sarilumab groups compared with placebo. In this study, reductions in the absolute neutrophil count were not associated with an increased incidence of infections or serious infections.ConclusionSarilumab 150 mg and sarilumab 200 mg every 2 weeks plus conventional synthetic DMARDs improved the signs and symptoms of RA and physical function in patients with an inadequate response or intolerance to anti‐TNF agents. Safety data were consistent with interleukin‐6 receptor blockade and the known safety profile of sarilumab.
The novel design used in this study permitted the use of a smaller number of patients receiving placebo to test the efficacy of the four novel compounds. The NK(3) and 5-HT(2A/2C) antagonists showed evidence of efficacy in the treatment of schizophrenia and schizoaffective disorder. Study limitations preclude a definitive conclusion on the efficacy of CB(1) and NTS(1) antagonists in the treatment of schizophrenia. Further study of these two promising nondopaminergic mechanisms to treat schizophrenia and schizoaffective disorder appears indicated.
