ObjectivesTo evaluate the efficacy and safety of different doses and regimens of filgotinib, an oral Janus kinase 1 inhibitor, as add-on treatment to methotrexate (MTX) in patients with active rheumatoid arthritis (RA) and inadequate response to MTX.MethodsIn this 24-week phase IIb study, patients with moderate-to-severe active RA receiving a stable dose of MTX were randomised (1:1:1:1:1:1:1) to receive placebo or 50, 100 or 200 mg filgotinib, administered once daily or twice daily. Primary end point was the percentage of patients achieving a week 12 American College of Rheumatology (ACR)20 response.ResultsOverall, 594 patients were randomised and treated. At week 12, significantly more patients receiving filgotinib 100 mg once daily or 200 mg daily (both regimens) achieved an ACR20 response versus placebo. For other key end points at week 12 (ACR50, ACR-N, Disease Activity Score based on 28 joints and C reactive protein value, Clinical Disease Activity Index, Simplified Disease Activity Index and Health Assessment Questionnaire-Disability Index), differences in favour of 100  or 200 mg filgotinib daily were seen versus placebo; responses were maintained or improved through to week 24. Rapid onset of action and dose-dependent responses were observed for most efficacy end points and were associated with an increased haemoglobin concentration. No significant differences between once-daily and twice-daily regimens were seen. Treatment-emergent adverse event rates were similar in placebo and filgotinib groups. Serious infections occurred in one and five patients in the placebo and filgotinib groups, respectively. No tuberculosis or opportunistic infections were reported.ConclusionsFilgotinib as add-on to MTX improved the signs and symptoms of active RA over 24 weeks and was associated with a rapid onset of action. Filgotinib was generally well tolerated.Trial registration number:NCT01888874.

ObjectivesTo evaluate the efficacy and safety of different doses of filgotinib, an oral Janus kinase 1 inhibitor, as monotherapy in patients with active rheumatoid arthritis (RA) and previous inadequate response to methotrexate (MTX).MethodsIn this 24-week phase IIb study, patients with moderately to severely active RA were randomised (1:1:1:1) to receive 50, 100 or 200 mg filgotinib once daily, or placebo, after a ≥4-week washout from MTX. The primary end point was the percentage of patients achieving an American College of Rheumatology (ACR)20 response at week 12.ResultsOverall, 283 patients were randomised and treated. At week 12, significantly more patients receiving filgotinib at any dose achieved ACR20 responses versus placebo (≥65% vs 29%, p<0.001). For other key end points at week 12 (ACR50, ACR70, ACR-N, Disease Activity Score based on 28 joints and C reactive protein, Clinical Disease Activity Index, Simplified Disease Activity Index and Health Assessment Questionnaire-Disability Index) significant differences from baseline in favour of filgotinib 100 and 200 mg versus placebo were seen; responses were maintained or improved through week 24. Rapid onset of action was observed for most efficacy end points. Dose-dependent increases in haemoglobin were observed. The percentage of patients with treatment-emergent adverse events (TEAE) was similar in the placebo and filgotinib groups (∼40%). Eight patients on filgotinib and one on placebo had a serious TEAE, and four patients, all of whom received filgotinib, experienced a serious infection. No tuberculosis or opportunistic infections were reported.ConclusionsOver 24 weeks, filgotinib as monotherapy was efficacious in treating the signs and symptoms of active RA, with a rapid onset of action. Filgotinib was generally well tolerated.Trial registration numberNCT01894516.

ObjectivesTo evaluate efficacy and safety of immediate switch from upadacitinib to adalimumab, or vice versa, in patients with rheumatoid arthritis with non-response or incomplete-response to the initial therapy.MethodsSELECT-COMPARE randomised patients to upadacitinib 15 mg once daily (n=651), placebo (n=651) or adalimumab 40 mg every other week (n=327). A treat-to-target study design was implemented, with blinded rescue occurring prior to week 26 for patients who did not achieve at least 20% improvement in both tender and swollen joint counts (‘non-responders’) and at week 26 based on Clinical Disease Activity Index (CDAI) >10 (‘incomplete-responders’) without washout.ResultsA total of 39% (252/651) and 49% (159/327) of patients originally randomised to upadacitinib and adalimumab were rescued to the alternate therapy. In both switch groups (adalimumab to upadacitinib and vice versa) and in non-responders and incomplete-responders, improvements in disease activity were observed at 3 and 6 months following rescue. CDAI low disease activity was achieved by 36% and 47% of non-responders and 45% and 58% of incomplete-responders switched to adalimumab and upadacitinib, respectively, 6 months following switch. Overall, approximately 5% of rescued patients experienced worsening in disease activity at 6 months postswitch. The frequency of adverse events was similar between switch groups.ConclusionsThese observations support a treat-to-target strategy, in which patients who fail to respond initially (or do not achieve sufficient response) are switched to a therapy with an alternate mechanism of action and experience improved outcomes. No new safety findings were observed despite immediate switch without washout.

Objective: to evaluate the clinical efficacy of the rituximab biosimilar Acellbia® at a dose of 600 mg intravenously at a 2-week interval in patients with active rheumatoid arthritis (RA) 12 and 24 weeks after initiation of treatment.Subjects and methods. Examinations were made in 20 active seropositive RA patients who had not been previously treated with biological agents (BAs), but received two infusions of the rituximab biosimilar Acellbia® at a dose of 600 mg intravenously at a 2-week interval during stable therapy with methotrexate (MT) and glucocorticoids (GCs). The European League Against Rheumatism (EULAR) response criteria (Disease Activity Score 28 (DAS28), Clinical Disease Activity Index (CDAI), and Simplified Disease Activity Index) and the American College of Rheumatology (ACR) criteria were used to evaluate the efficiency of Acellbia® therapy. Disease remission was identified by DAS28 and 2011 ACR/EULAR criteria. The safety profile (the frequency of all reported adverse events) corresponds to the data on the safety of rituximab (MabThera®).Results and discussion. At the time of inclusion, median DAS28 was 5.6 [4.9; 6.8], SDAI – 27.1 [23.0; 39.9], and CDAI – 26.6 [22.2; 37.0]. At week 12 after initiation of Acellbia® therapy, they decreased to 4.2 [3.24; 4.75], 14.4 [8.5; 20.7], and 13.2 [7.9; 19.0] respectively, which remained at 24-week follow-up (p<0.01). At week 12, the frequencies of ACR 20%, 50%, 70% improvements were 70, 55, and 5%; at week 24, these were 75, 45, and 15%, respectively. A good or moderate EULAR response at week 24 was observed in 25 and 60% of patients, respectively. At week 24, DAS28, SDAI, and CDAI remissions were achieved by 4 (20%), 2 (10%), and 1 (5%); low disease activity – by 4 (20%), 5 (25%), and 6 (30%) patients, respectively; high disease activity as measured by SDAI and CDAI remained in 3 (15%) patients. Two patients (10%) met the 2011 ACR/EULAR remission criteria at 24 weeks.Conclusion. The rituximab biosimilar Acellbia® 600 mg used in patients with active seropositive RA is clinically effective and comparable in the safety profile as shown in investigations of the brand-name MabThera® (F. Hoffman-La Roche Ltd., Switzerland) at a low dose (500 mg), as well as the first BA.

ObjectivesTo evaluate efficacy and safety of abatacept+methotrexate (MTX) in biologic-naive, anticitrullinated protein antibody (ACPA)-positive Japanese patients with active rheumatoid arthritis (RA) and early erosion versus placebo+MTX.MethodsIn this phase IV, multicentre, double-blind study (NCT01758198), patients were randomised (1:1) to receive intravenous abatacept (~10 mg/kg) or placebo, plus MTX (≥6 mg/week). Primary efficacy objectives were to compare American College of Rheumatology 20 (ACR20) response rates at week 16 and mean change from baseline in van der Heijde-modified total Sharp score (vdH-mTSS) at week 24 between abatacept+MTX and placebo+MTX groups.ResultsOverall, 203 and 202 patients received abatacept+MTX and placebo+MTX, respectively. At week 16, ACR20 response rates were higher in the abatacept (75.4%) versus placebo group (27.7%; p<0.001). Mean change from baseline in vdH-mTSS at week 24 was 0.84 in the abatacept and 1.26 in the placebo group (p=0.017). Radiographic non-progression rates (change in vdH-mTSS≤smallest detectable change (1.9)) were 88.1% and 75.4% in abatacept and placebo groups, respectively. Adjusted mean change from baseline in Disease Activity Score 28 (C-reactive protein) (DAS28 (CRP)) at week 16 demonstrated a numerically greater reduction in the abatacept versus placebo group. Proportions of patients with DAS28 (CRP), Simplified Disease Activity Index and Clinical Disease Activity Index remission up to week 52 were higher in the abatacept versus placebo group. The abatacept safety profile was consistent with previous observations.ConclusionsCompared with MTX alone, abatacept+MTX improved clinical symptoms and inhibited structural damage progression in ACPA-positive, Japanese patients with RA, early erosion and inadequate response to MTX.

Background:However baricitinib, an oral selective inhibitor of Janus kinase (JAK) 1 and 2, improved signs and symptoms of rheumatoid arthritis (RA), it is unknown who can taper or stop baricitinib and strategies for de-escalation.Objectives:We analyze predictors of tapering of withdrawal failure in rheumatoid arthritis (RA) patients treated with baricitinib. This study will assess and compare (1) characteristic of patients who achieve remission (REM) or low disease activity (LDA) as who can taper baricitinib and (2) two de-escalation methods, rapidly and gradually de-escalation in patients who respond first-line therapy.Methods:Cases were recruited to SHin-yokohama Arthritis REgister (SHARE) between 2015 and 2019 (n=3,674). Patients were diagnosed according to ACR/EULAR 2010 classification criteria, and treated with DMARDs which included baricitinib 2mg/day (n=154). In 154 cases, Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire-Disability Index (HAQ-DI), anti-CCP2 and patients clinical parameters were analyzed. Two de-escalation methods were compared in this study. In rapidly de-escalation methods, baricitinib were stopped in patients with stable REM/LDA over 12 weeks. In gradually de-escalation methods, baricitinib were decreased to 50%, 42%, 28%, 14% in order with stable REM/LDA over 12 weeks.Results:In 154 (Male25, Female129 cases, RA duration 11.4+/-8.0 years) cases, CDAI at baricitinib-start was 20.6+/-12.4 and titer of anti-CCP2 was 242.6+/-516.5 U/ml. 126 cases (81.8%) were more than 2 years of RA duration and 49 cases (31.8%) had persistency of signs and/or symptoms suggestive of inflammatory RA disease activitiy, despite prior treatment with csDMARDs and at least two biologic DMARDs. 33 cases (21.4%) were biologic DMARDs naive.(1)”Multivariate logistic regression examined the predictors to detect who can taper baricitinib” However there were no differences in duration of RA, onset age of RA, biologics and/or JAK inhibitors naïve, anti-CCP2 titer and CDAI at the start baricitinib, patients who showed decrease of CDAI at 12 weeks were correlated with achievement of remission (REM) or low disease activity (LDA) in patients treated with baricitinib (OR 0.964, 95%CI 0.934-0.996, p=0.010). ROC analysis of ΔCDAI at 12 weeks is cut-off value of -6.6 (p=0.011).(2)”Comparison of sustained REM and/or LDA rate between rapidly and gradually de-escalation of baricitinib in rheumatoid arthritis” 11 cases were tapered baricitinib with rapidly de-escalation methods and 60 patients were with gradually de-escalation. Mean times to start taper baricitinib in rapidly and gradually de-escalation group were 4.6+/-1.6 months and 5.9+/-2.2 months respectively. Gradually de-escalation methods showed less relapse rate compared with rapidly de-escalation after tapered baricitinib for 6 months (18.3% vs. 54.5%, p=0.018). There were no differences in clinical features such as anti-CCP2, CDAI and administration period of baricitinib between non-relapse and relapse patients in gradually escalation methods.Conclusion:A combination of ΔCDAI at 12 weeks and tapering baricitinib using gradually de-escalation methods may help to predict successful baricitinib deduction in RA patients with sustained clinical REM and/or LDA.References:[1]Ann Rheum Dis. 2019;78:171[2]Rheumatology. 2019;58:110[3]An Rheum Dis. 2015;74:19Disclosure of Interests:None declared

ObjectiveTo evaluate the efficacy and safety of olokizumab (OKZ) in patients with active rheumatoid arthritis despite treatment with methotrexate (MTX).MethodsIn this 24-week multicentre, placebo-controlled, double-blind study, patients were randomised 1:1:1 to receive subcutaneously administered OKZ 64 mg once every 2 weeks, OKZ 64 mg once every 4 weeks, or placebo plus MTX. The primary efficacy endpoint was the proportion of patients achieving an American College of Rheumatology 20% (ACR20) response at week 12. The secondary efficacy endpoints included percentage of subjects achieving Disease Activity Score 28-joint count based on C reactive protein <3.2, Health Assessment Questionnaire Disability Index at week 12, ACR50 response and Clinical Disease Activity Index ≤2.8 at week 24. Safety and immunogenicity were assessed throughout the study.ResultsA total of 428 patients were randomised. ACR20 responses were more frequent with OKZ every 2 weeks (63.6%) and OKZ every 4 weeks (70.4%) than placebo (25.9%) (p<0.0001 for both comparisons). There were significant differences in all secondary efficacy endpoints between OKZ-treated arms and placebo. Treatment-emergent serious adverse events (TESAEs) were reported by more patients in the OKZ groups compared with placebo. Infections were the most common TESAEs. No subjects developed neutralising antidrug antibodies.ConclusionsTreatment with OKZ was associated with significant improvement in signs, symptoms and physical function of rheumatoid arthritis without discernible differences between the two regimens. Safety was as expected for this class of agents. Low immunogenicity was observed.Trial registration numberNCT02760368.

Objective.Sustained remission in rheumatoid arthritis (RA) results in healthcare utilization cost savings. We evaluated the variation in estimates of savings when different definitions of remission [2011 American College of Rheumatology/European League Against Rheumatism Boolean Definition, Simplified Disease Activity Index (SDAI) ≤ 3.3, Clinical Disease Activity Index (CDAI) ≤ 2.8, and Disease Activity Score-28 (DAS28) ≤ 2.6] are applied.Methods.The annual mean healthcare service utilization costs were estimated from provincial physician billing claims, outpatient visits, and hospitalizations, with linkage to clinical data from the Alberta Biologics Pharmacosurveillance Program (ABioPharm). Cost savings in patients who had a 1-year continuous period of remission were compared to those who did not, using 4 definitions of remission.Results.In 1086 patients, sustained remission rates were 16.1% for DAS28, 8.8% for Boolean, 5.5% for CDAI, and 4.2% for SDAI. The estimated mean annual healthcare cost savings per patient achieving remission (relative to not) were SDAI $1928 (95% CI 592, 3264), DAS28 $1676 (95% CI 987, 2365), and Boolean $1259 (95% CI 417, 2100). The annual savings by CDAI remission per patient were not significant at $423 (95% CI −1757, 2602). For patients in DAS28, Boolean, and SDAI remission, savings were seen both in costs directly related to RA and its comorbidities, and in costs for non-RA-related conditions.Conclusion.The magnitude of the healthcare cost savings varies according to the remission definition used in classifying patient disease status. The highest point estimate for cost savings was observed in patients attaining SDAI remission and the least with the CDAI; confidence intervals for these estimates do overlap. Future pharmacoeconomic analyses should employ all response definitions in assessing the influence of treatment.
