Background:PATERA is an ongoing phase 3 international double-blind, placebo-controlled clinical study of netakimab (NTK) in psoriatic arthritis (PsA) (NCT03598751). Netakimab (NTK) is an anti-interleukin-17A monoclonal antibody approved for psoriasis, ankylosing spondylitis, PsA in Russia and Belarus.Objectives:A subanalysis was performed to define the impact of NTK on PsA activity depending on the presence of axial disease: a subset of patients with inflammatory back pain (IBP) according to self-reported ASAS IBP criteria, 2009 (IBP(+) was compared to those without IBP (IBP(-)).Methods:194 eligible adult patients with PsA fulfilling the CASPAR criteria, with inadequate response to csDMARD or one TNFi, were randomly assigned to receive NTK 120mg or placebo at weeks 0,1,2,4,6,8,10,14,18,22. Patients with missing values for categorical variables were considered as non-responders in the analysis. For quantitative variables, missing values were replaced using the multiple imputation method.Results:97 PsA patients (N=54 IBP(+), N=43 IBP(-)) received NTK. Both subpopulations were comparable in gender, age and PsA activity at baseline. The treatment led to a pronounced decline in PsA activity in both subpopulations, significant differences between arms were observed only in DAPSA remission and very low disease activity (VLDA) at week 24 (Figure 1A). Changes from baseline in DAS28-CRP were consistent between IBP(+) and IBP(-) patients with a rapid decline during the first month with further improvement up to week 24 (Figure 1B). A similar trend was observed PsA-specific composite responder index (PSARC) (data not shown). A comparable percentage of IBP(+) and IBP(-) patients achieved PSARC at each timepoint of evaluation with 87% and 86% of responders respectively at week 24.Conclusion:NTK significantly improved PsA activity regardless of the presence of IBP.Figure 1.PsA activity after 24-week treatment with NTK.

Background:Inflammatory back pain (IBP) is a common symptom of axial disease in patients with psoriatic arthritis (PsA). The reported prevalence of axial disease in patients with PsA is quite variable and must be taken into account while choosing treatment strategy. Netakimab (NTK) is an anti-interleukin-17A monoclonal antibody approved for psoriasis, ankylosing spondylitis, PsA in Russia and Belarus.Objectives:A subanalysis was aimed to investigate the ACR (American College of Rheumatology) 20/50/70 response rate in PsA patients with/without the axial disease, defined by the presence of IBP according to self-reported ASAS IBP criteria, 2009 at baseline.Methods:PATERA is an ongoing phase 3 international double-blind, placebo-controlled clinical study (NCT03598751). 194 adult patients with PsA (CASPAR criteria, 2006) with inadequate response to csDMARD or one TNFi, were randomly assigned to receive NTK 120mg or placebo at weeks 0,1,2,4,6,8,10,14,18,22. The ACR response was calculated in NTK-treated patients with IBP (IBP(+)) and NTK-treated patients without IBP (IBP(-)) according to self-reported ASAS IBP criteria, 2009. Patients with missing values for categorical variables were considered as non-responders in the analysis.Results:97 PsA patients (N=54 IBP(+), N=43 IBP(-)) received NTK. Both subpopulations were comparable in gender, age, and PsA activity at baseline. There were no significant differences in ACR20 achievement between the groups (Figure 1). The percentage of patients with ACR50 was significantly (p<0.05) higher in the IBP(-) subpopulation at weeks 4-20 (data not shown), but not at week 24 with 63% IBP(+) and 79% IBP(-) responders (p≥0.05). Similarly, IBP(+) patients had a lower frequency of ACR70 response (Figure 1).Conclusion:NTK is effective in PsA treatment irrespectively of the presence of axial disease. Both IBP(-) and IBP(+) subpopulations achieved ACR20/50/70 as well, however, the benefit in IBP(-) patients was more pronounced.Figure 1ACR response ratesAcknowledgements:This study was sponsored by JSC BIOCAD.Disclosure of Interests:Tatiana Korotaeva Speakers bureau: Abbvie, Biocad, Eli Lilly, Johnson & Johnson, Janssen, Novartis, Pfizer, UCB, Inna Gaydukova Speakers bureau: Abbvie, Biocad, Eli Lilly, MSD, Novartis, Pfizer, Sandoz, V Mazurov: None declared., Aleksey Samtsov: None declared., Vladislav Khayrutdinov: None declared., Andrey Bakulev: None declared., Alena Kundzer: None declared., Nikolaj Soroka: None declared., Anna Eremeeva Employee of: Biocad.

Background:Netakimab (NTK) is an anti-interleukin-17A monoclonal antibody approved for psoriasis, ankylosing spondylitis, psoriatic arthritis (PsA) in Russia and Belarus. PATERA is an ongoing phase 3 international double-blind, placebo-controlled clinical study of NTK in PsA (NCT03598751).Objectives:A subanalysis was performed to assess the effect of NTK on domains of the 5-level EuroQol 5 Dimensions questionnaire (EQ-5D-5L) in patients with inflammatory back pain (IBP) (IBP(+)) and without (IBP(-)) at baseline according to self-reported ASAS IBP criteria, 2009.Methods:194 adult patients with PsA (CASPAR criteria, 2006) with inadequate response to csDMARD or one TNFi, were randomly assigned to receive NTK 120mg or placebo at weeks 0,1,2,4,6,8,10,14,18,22. The proportion of patients reported >1 problem in each domain was evaluated. Patients with missing values were considered as non-responders in the analysis.Results:97 PsA patients (N=54 IBP(+), N=43 IBP(-)) received NTK. The subpopulations didn’t differ significantly in gender, age, and PsA activity at baseline. Comparable percentage of patients reported any problems for each domain at baseline (p≥0.05) (data not shown). IBP(-) subpopulation had a greater improvement for all domains except of anxiety/depression. The absolute declines for IBP(+) vs IBP(-) patients were as followed: 24.1% vs 41.9% (mobility), 18.5 vs 41.9% (self-care), 24.0% vs 51.1% (usual activities), 24.1% vs 37.2% (pain/discomfort), 33.3% vs 9.3% (anxiety/depression). However, the only significant difference between IBP(+) and IBP(-) was observed in usual activity (Figure 1).Conclusion:NTK resulted in the growing improvement of each EQ-5D-5L domain through 24 weeks irrespectively of the presence of IBP. IBP(-) subjects showed trend to greater benefit compared to IBP(+).Figure 1Percentage of patients reported any problems in (A) pain/discomfort, (B) in usual activity at each visitAcknowledgements:This study was sponsored by JSC BIOCAD.Disclosure of Interests:Inna Gaydukova Speakers bureau: Abbvie, Biocad, Eli Lilly, MSD, Novartis, Pfizer, Sandoz, Tatiana Korotaeva Speakers bureau: Abbvie, Biocad, Eli Lilly, Johnson & Johnson, Janssen, Novartis, Pfizer, UCB, V Mazurov: None declared., Aleksey Samtsov: None declared., Vladislav Khayrutdinov: None declared., Andrey Bakulev: None declared., Alena Kundzer: None declared., Nikolaj Soroka: None declared., Anna Eremeeva Employee of: Biocad.

Objective: to analyze the data available in the literature on the efficacy and safety of ixekizumab (IXE) and adalimumab (ADA) via their direct comparisons in the treatment of psoriatic arthritis (PsA).Patients and methods. The results of the SPIRIT H2H study were analyzed, the aim of which was to investigate the potential superiority of IXE to ADA for arthritis and skin manifestations in a group of patients with active PsA, stable plaque psoriasis with an inadequate response to synthetic disease-modifying antirheumatic drugs (sDMARDs) who had not previously received biological agents (BAs).Design: a 52-week multicenter, randomized, parallel-group study. The patients were randomized 1:1 to open IXE or ADA administration groups for 52 weeks. This review presents the data obtained at 24-week follow-up.Of the 684 screened patients, 566 (82.7%) were included in the study; moreover, the distribution of the patients was equal between the ADA (n=283) and IXE (n=283) groups. At 6 months, 269 (95%) patients in the ADA group and 262 (93%) in the IXE one continued to participate in the study. Efficacy analysis was made based on the achievement of the primary endpoint that was considered to be related to the relative number of patients, who had simultaneously achieved improvements in the joints and skin according to the ACR50 and PASI100 criteria.Results and discussion. At 24 weeks, the proportion of patients who had simultaneously achieved ACR50 and PASI100 responses was significantly higher in the IXE group (36%) than in the ADA one (28%) (p=0.036). It was found that the IXE group was not inferior to the ADA one in terms of ACR50 response rates (in 51% (IXE) and 47% (ADA) patients) and was superior in achieving PASI100 response rates (in 60% (IXE) and 47% (ADA) patients) (p=0.001). The IXE group was recorded to have a higher response than the ADA group and in terms of other manifestations of the disease: the severity of skin and nail psoriasis, enthesitis, remission achievement, minimal and very low disease activity, and improved quality of life. Comparable effectiveness was noted for the effect of the drugs on dactylitis, as well as for the simultaneous achievement of remission and low disease activity in psoriatic arthritis according DAPSA. Serious adverse events (SAEs) were recorded in 8.5% (ADA) and 3.5% (IXE) patients.The safety and tolerability of both BAs corresponded to their previously presented safety profile. The findings were also confirmed at 52-week follow-up, presented at the Meetings of the American College of Rheumatology in November 2019 and the European League Against Rheumatism in June 2020, and published in the leading journals of rheumatology.Conclusion. The first randomized placebo-controlled study (SPIRIT H2H) directly comparing the two BAs with different mechanisms of action demonstrated the advantage of IXE over ADA in simultaneously reducing the activity of arthritis and psoriasis and showed their comparable efficacy comparable efficacy regarding joint symptoms. The use of IXE versus ADA was accompanied by the more frequent achievement of a combined endpoint related to the signs of joint and skin damages in patients with PSA, as well as by the quantitatively lower frequency of SAEs in patients with active PSA who had failed previous sDMARD therapy. The findings are of great importance for clinical practice from the point of view of the reasonable choice of a treatment strategy in these patients.

Objective: The primary aim of the study was to assess the potential differences in clinical features, disease activity, function and impact of disease between Psoriatic Arthritis (PsA) patients with oligoarticular and polyarticular involvement. Methods: Consecutive PsA patients attending our unit were divided into 2 groups: 1) Oligoarticular (<5 involved joints with or without enthesitic/axial manifestations) and 2) Polyarticular (≥5 joints with or without enthesitic/axial manifestations). A full clinical examination with the assessment of disease characteristics, disease activity (DAPSA, MDA), function (HAQ-DI) and impact of disease (PsAID-12) was performed. Furthermore, a 6-month follow-up evaluation was carried out in order to assess disease differences at baseline and at follow-up. Results: Of the 102 enrolled patients, oligoarticular subset was present in 63 (61.7%), while 39 (38.3%) patients had polyarticular involvement. Patients with oligoarticular subset showed, at baseline evaluation, lower values of global disease activity assessed by physician, HAQ-DI and DAPSA compared to patients with polyarticular pattern. No differences in the impact of disease (PsAID), patient global assessment of disease activity or pain were found. At 6-month follow-up, no significant changes in each group occurred. Conclusion: Our study showed some differences in patients with oligoarticular and polyarticular involvement in terms of disease activity and HAQ-DI, while the overall impact of the disease and the presence of enthesitis, dactylitis and axial disease seem to be similar, with no substantial changes after 6-month follow-up. These results could mean that clinical phenotype might not be responsible for the impact of the disease perceived by the patient.

Objective.We aimed to determine disease severity and treatment of patients with psoriatic arthritis (PsA) in rheumatology practices in Canada through the PsA Assessment in Rheumatology (PAIR) study.Methods.Rheumatologists who were members of the Canadian Rheumatology Association were asked to complete a form for each patient addressing demographic questions, history, clinical examination, and patient-reported outcomes. Results were compared with a cohort seen in a PsA clinic during the same period.Results.From across Canada, 22 rheumatologists from 5 provinces submitted information about 233 consecutive patients with PsA [145 men (62.2%), 88 women (37.8%), mean age 53.2 yrs (± 12.7), 88.4% disease duration > 2 yrs]. A majority (80.7%) fulfilled ClASsification for Psoriatic ARthritis (CASPAR) criteria, and 30% had taken no disease-modifying antirheumatic drugs. Clinical joint damage was documented in 60% of the patients, active skin disease in 70%, and nail lesions in 32%. Only 22% were rated as having moderate to high disease activity, while 52% were rated as low disease activity and 26% were deemed in remission. The decision was based on joint counts, patient global assessment, physician global assessment, and acute-phase reactants. Twenty-seven percent of the patients were to have their medications changed based on the current visit, the majority for inadequate response to medications. Patients in the PAIR cohort had more inflamed joints but similar damage to those in the PsA clinic.Conclusion.Patients with PsA seen in regular rheumatology practice fulfill CASPAR criteria, have active disease, and more than half have joint damage. The majority have low activity or are in remission.

Background:In patients with spondyloarthritis (SpA), root joint diseases (RJD), i.e. hip or shoulder involvement, may be associated with a distinct disease phenotype compared to those with other affected joints. The ASAS-PerSpA study (PERipheral involvement in SPondyloArthritis) [1], offers a unique opportunity to study the phenotypes of patients with RJD in a global cohort.Objectives:Primary objective was to compare the clinical characteristics of SpA patients with and without RJD. Secondary objectives were to compare the prevalence of RJD across the different SpA subtypes and the different regions of the world, compare the severity of axial disease as well as the disease burden in SpA patients with and without RJD.Methods:This is a post-hoc analysis of the ASAS-PerSpA study, which included 4,465 patients with any subtype of SpA (axial SpA (axSpA), peripheral SpA (pSpA), psoriatic arthritis (PsA), inflammatory bowel disease associated SpA (IBD-SpA), reactive arthritis (ReA) and Juvenile SpA (Juv-SpA)) according to the rheumatologist’s diagnosis. RJD was defined as a positive answer by the investigator to the following question: “Do you consider that the patient has ever suffered from RJD (e.g. hip, shoulder) related to SpA?” In case of a positive answer, a potential specific treatment (e.g. Total Articular Replacement) was investigated. The patient’s characteristics were compared between those with and without RJD involvement, using Chi-2 or Fisher exact test for the categorical variables and t-test for the continuous variables. Two separate multivariable stepwise binary logistic regression analyses were conducted to identify factors associated with the dependent variables “hip involvement” and “shoulder involvement”.Results:RJD occurred in 1,503 patients (33.7%), with more prevalent hip (24.2%) than shoulder (13.2%) involvement. The prevalence of RJD as a group was the highest in Juv-SpA (52.7%), followed by pSpA (44.3%) and axSpA (33.9%). The highest prevalence of RJD was found in Asia and the lowest in Europe and North America. Among patients with hip involvement, 6.0% had a history of hip replacement (highest in the Middle East and North Africa and Latin America); among patients with shoulder involvement, 0.8% had a history of shoulder replacement. Hip had a distinct pattern of associations compared to shoulder involvement (Figure 1). Hip involvement was significantly associated with the SpA main diagnosis (highest in pSpA, lowest in PsA), younger age at first SpA symptom, lower prevalence of family history of psoriasis, positive HLA-B27, occiput-to-wall distance>0, and treatment with cs-DMARDs and b-DMARDs. Shoulder involvement was associated with the SpA main diagnosis (highest in Juv-SpA and pSpA, lowest in axSpA), older age at first SpA symptom, higher prevalence of enthesitis, dactylitis, tender joints count, IBD, occiput-to-wall distance>0, EQ5D score and treatment with cs-DMARDs.Conclusion:Hip involvement was more prevalent than shoulder involvement in patients with SpA, and had a distinct phenotype resembling axial disease whereas shoulder involvement was mostly associated with features of peripheral disease. Hip and shoulder involvement should be analyzed separately in future studies rather than under the RJD entity.References:[1]Lopez-medina, C. et al.

The Impact

Background:Following RA treatment recommendations, most people with rheumatoid arthritis (RA) begin targeted therapy with TNF inhibitors (TNFi), even though inadequate response to TNFi therapies is widespread. Treatment changes from one medication to the next are currently fueled by disease-activity measures and eventually result in disease control for most patients; however, this “trial-and-error” approach wastes precious time on ineffective treatments. A delay in reaching treat-to-target goals has a negative effect on patient burden and, possibly, disease progression.1 Useful predictors for TNFi response have been challenging to identify but a specific molecular signature response classifier (MSRC) test was shown to be predictive for inadequate response to TNFi therapies.2 The impact of such identification has the potential to result in improved patient outcomes, but further validation would be welcome, especially for response criteria other than ACR50, and in a stringent treat-to-target setting with lower baseline disease activity.Objectives:To validate the predictive value of the MSRC test in identifying those patients who do not meet EULAR good response criteria after 6 months of TNFi treatment.Methods:Data from a prospective cohort study conducted in the Sint Maartenskliniek (Nijmegen, the Netherlands) of RA patients who started adalimumab or etanercept TNFi as their first biologic were included.3 Baseline RNA samples and clinical assessments were used to identify patients who had a molecular signature1 of non-response to TNFi therapy. Outcomes were calculated at six months using DAS28-CRP-based EULAR good response, and high and low confidence responders and non-responders were identified using Monte Carlo simulation with 2,000 repeats and 70% precision cut off. Outcome measurements were blinded for test results. Treatment switch before 6 months was imputed as non-response. Odds ratios and area under the ROC curve (AUC) assessments were used to evaluate the ability of the MSRC test to predict inadequate response at 6 months against EULAR good response criteria.Results:A total of 68 out of 88 RA patients were identified to have a high-confidence response status and were included in analyses (Table 1). EULAR good response was observed in 45.5% (31/68) of patients. Patients were stratified according to detection of a molecular signature of non-response with an AUC of 0.61. The odds that a patient with the molecular signature of non-response at baseline failed to achieve a EULAR good response at 6 months was four times greater than that of a patient lacking the molecular signature (odds ratio 4.0, 95% confidence interval 1.2-13.3).Table 1.Patient demographicsCharacteristicRA patients (N = 68)Age, median (SD)57 (11)Female, n (%)43 (63.2)CCP positive, n (%)34 (50.0)RF positive, n (%)38 (55.9)Prescribed adalimumab at baseline, n (%)11 (16.2)Prescribed etanercept at baseline, n (%)57 (83.8)Conclusion:In this validation study, the molecular signature of non-response identified patients who did not fulfill the EULAR good response criteria to TNFi therapies. The patient selection process for this study had limitations; additional analysis in an alternative cohort would further verify the performance of the MSRC test. Nevertheless, the test, previously validated for ACR50, now has been validated using EULAR good response in a treat-to-target setting.References:[1]Schipper LG et al, Time to achieve remission determines time to be in remission.

Background:There are still unmet needs in the treatment of psoriatic arthritis (PsA), including in terms of treatment persistence, which is a function of effectiveness, safety and patient satisfaction. Ustekinumab (UST) was the first new biologic drug to be developed for the treatment of PsA after tumour necrosis factor inhibitors (TNFi).Objectives:To compare treatment persistence, effectiveness and safety of UST and TNFi in Italian patients within the PsABio cohort.Methods:PsABio (NCT02627768) is an observational study of 1st/2nd/3rd-line UST or TNFi treatment in PsA in 8 European countries. The current analysis set includes 222 eligible patients treated in 15 Italian centres, followed to Month 12 (±3 months). Treatment persistence/risk of stopping was analysed using Kaplan−Meier (KM) and Cox regression analysis. Proportions of patients reaching minimal disease activity (MDA)/very low disease activity (VLDA) and clinical Disease Activity Index for PsA (cDAPSA) low disease activity (LDA)/remission were analysed using logistic regression, including propensity score (PS) adjustment for imbalanced baseline covariates, and non-response imputation of effectiveness endpoints if treatment was stopped/switched before 1 year. Last observation carried forward data are reported.Results:Of patients starting UST and TNFi, 75/101 (74.3%) and 77/121 (63.6%), respectively, persisted with treatment at 1 year. The observed mean persistence was 410 days for UST and 363 days for TNFi. KM curves and PS-adjusted hazard ratios confirmed significantly higher persistence (hazard ratio [95% confidence interval (CI)]) for UST versus TNFi overall (0.46 [0.26; 0.82]; Figure 1). Persistence was also higher for UST than TNFi in patients receiving monotherapy without methotrexate (0.31 [0.15; 0.63]), in females (0.41 [0.20; 0.83]), and in patients with body mass index (BMI) <25 kg/m2 (0.34 [0.14; 0.87]) or >30 kg/m2 (0.19 [0.06; 0.54]). There was no significant difference in persistence between treatments in patients with BMI 25−30 kg/m2. While patients receiving 1st- and 3rd-line UST or TNFi showed similar risk of discontinuation (0.60 [0.27; 1.29] and 0.36 [0.10; 1.25], respectively), patients receiving 2nd-line UST showed better persistence than those receiving 2nd-line TNFi (0.33 [0.13; 0.87]). Other factors added to the PS-adjusted Cox model did not show significant effects. In patients with available follow-up data, the mean (standard deviation) baseline cDAPSA was 26.3 (15.4) for UST and 23.5 (12.3) for TNFi; at 1-year follow-up, 43.5% of UST- and 43.6% of TNFi-treated patients reached cDAPSA LDA/remission. MDA was reached in 24.2% of UST- and 28.0% of TNFi-treated patients, and VLDA in 12.5% of UST- and 10.2% of TNFi-treated patients. After PS adjustment (stoppers/switchers as non-responders), odds ratios (95% CI) at 1 year did not differ significantly between UST and TNFi groups for reaching cDAPSA LDA/remission (1.08 [0.54; 2.15]), MDA (0.96 [0.45; 2.05]) or VLDA (0.98 [0.35; 2.76]). In total, 23 (20.4%) patients reported ≥1 treatment emergent adverse event with UST and 30 (22.2%) with TNFi; 6 (5.3%) and 10 (7.4%) patients, respectively, discontinued treatment because of an adverse event.Conclusion:In the Italian PsABio cohort, UST had better overall persistence compared with TNFi, as well as in specific subgroups: females, patients on monotherapy without methotrexate, with BMI <25 or >30 kg/m2, and patients receiving UST as 2nd-line treatment. At 1 year, both treatments showed similar effectiveness, as measured by cDAPSA responses and MDA/VLDA achievement.Acknowledgements:This study was funded by Janssen.
