Abstract
Background:Nintedanib has shown to slow FVC decline by 41ml over 52 weeks in systemic sclerosis-associated interstitial lung disease (SSc-ILD). However, the long-term effect of nintedanib treatment on ILD progression and mortality in SSc patients is so far unknown.Objectives:Here, the 52-week treatment efficacy of nintedanib was modeled and extrapolated on the long-term FVC course and survival in SSc-ILD patients from the European Scleroderma Trial and Research (EUSTAR) database.Methods:SSc patients from the EUSTAR database fulfilling the inclusion criteria of the SENSCIS trial (SSc classification criteria, ILD confirmed by imaging, disease duration of <7 years, FVC≥40%pred, diffusion capacity of the lung for carbon monoxide (DLCO) 30-89%pred); and matched for baseline characteristics as well as matched for the 52-week FVC change of SENSCIS patients were included (n=236). Linear mixed models including time, risk factors at baseline (sex, age, dyspnea class, DLCO%, CRP, modified Rodnan skin score, SSc subtype, SSc auto-antibodies, disease duration, synovitis and muscle weakness) were used to estimate the natural FVC course over time. On this natural course of FVC, the observed effect from the SENSCIS trial representing the absolute 52-week difference of FVC decline between the nintedanib and the placebo group was applied as continuous annual effect (SENSCIS effect model). Survival was estimated for both the natural course as well as the SENSCIS effect model using Cox regression.Results:Of the 236 included patients, 75% were females, 65% had diffuse cutaneous SSc. Mean age was 50.6 years, mean FVC 78.2%pred and DLCO 56.3%pred at time of inclusion. Mean FVC change after 12±3 months was -2.3 ±6.9%pred. These parameters were largely similar to the characteristics of the SENSCIS population.In the longitudinal follow up of this population, the natural course of FVC showed a total FVC decline of -16.3%pred over 5 years. With assumed SENSCIS effects (effects of nintedanib treatment reported in SENSCIS), the 5-year FVC decline was reduced to -10.3%pred (Figure 1).The reduced FVC progression translated into an improved survival. The natural 5-year survival of this SSc-ILD population was 88.2%. When extrapolating also a severe FVC decline early in the course, frequently terminated by early mortality of SSc patients excluding them from long-term outcome assessment, the estimated 5-year survival was reduced to 81.6%. When the SENSCIS effects on FVC were considered, the 5-year extrapolated survival was increased to 86.3% (Figure 2).Conclusion:Long-term experience of nintedanib treatment in SSc-ILD patients is lacking so far, therefore we modeled and extrapolated the 52-week treatment efficacy of nintedanib on the long-term FVC course and survival in SSc-ILD patients from the EUSTAR database. We could demonstrate a significant reduction of FVC decline by extrapolating the annual treatment effects of nintedanib from the SENSCIS trial from 1 to 5 years in EUSTAR. Translating these reductions of FVC decline into survival, the 5-year mortality rate was reduced from 18% to 13%.Disclosure of Interests:Anna-Maria Hoffmann-Vold Speakers bureau: Boehringer Ingelheim, Actelion, Roche, Merck Sharp & Dohme, Lilly, Consultant of: Actelion, Boehringer Ingelheim, Roche, Bayer, Merck Sharp & Dohme, ARXX, Lilly and Medscape, Grant/research support from: Boehringer Ingelheim, Dörte Huscher: None declared, Paolo Airò Speakers bureau: Boehringer Ingelheim, Consultant of: Bristol-Myers-Squibb, Novartis, Elisabetta Zanatta Speakers bureau: Boehringer Ingelheim, Actelion, GSK, Paid instructor for: GSK, Consultant of: Boehringer Ingelheim, GSK, Patricia Carreira Speakers bureau: Actelion, Boehringer Ingellheim, Janssen, GSK, Paid instructor for: Boehringer Ingelheim, Consultant of: AbbVie, Boehringer Ingelheim, VivaCell, Emerald Health Pharmaceuticals, Gesynta Pharma, Sanofi Genzyme, Grant/research support from: Roche, GSK, Yannick Allanore Consultant of: Honorarium received from Boehringer, MedsenicSanofi, Menarini, Grant/research support from: Grants received from Alpine, Ose Immunogenetics, Ulf Müller-Ladner Speakers bureau: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Alessandro Giollo: None declared, Maria Rosa Pozzi: None declared, CAROLINA SOUZA MULLER Speakers bureau: Boehinger Ingelheim, Janssen, Roche, LIBBS, Bristol-Myers-Squib, Radim Bečvář Consultant of: Actelion, Boehringer Ingelheim, Michele Iudici: None declared, Dominik Majewski Speakers bureau: Boehringer Ingelheim - 2 x paid as a speaker, Armando Gabrielli Grant/research support from: Pfizer, CSL Behring, Margarida Alves Employee of: Boehringer Ingelheim, Nils Schoof Employee of: Boehringer Ingelheim International GmbH, Oliver Distler Speakers bureau: Boehringer Ingelheim, Medscape, IQone, Roche, Consultant of: Abbvie, Acceleron Pharma, Amgen, AnaMar, Arxx Therapeutics, Baecon Discovery, Blade Therapeutics, Bayer, Boehringer Ingelheim, ChemomAb, Corbus Pharmaceuticals, CSL Behring, Galapagos NV, Glenmark Pharmaceuticals, GSK, Horizon (Curzion) Pharmaceuticals, Inventiva, iQvia, Italfarmaco, Kymera Therapeutics, Lilly, Medac, Mitsubishi Tanabe Pharma, MSD, Novartis, Pfizer, Roche, Sanofi, Serodapharm, Topadur, Target Bioscience and UCB, Grant/research support from: Kymera Therapeutics, Mitsubishi Tanabe

Abstract
Background:The expression of embryonic Homeobox (HOX) genes is tightly regulated based on anatomic location in human adult dermal and synovial fibroblasts. Previously, we showed that HOX-D10,-D11 and -D13 are higher expressed in synovial fibroblasts from small distal joints from the hands and feet, in particular in digits II-V and wrists compared to thumb and that this expression pattern is epigenetically imprinted1. The consequences of the tightly restricted expression of these transcription factors are largely unknown.Objectives:To elucidate the function of HOXD10, -D11 and -D13 in synovial fibroblasts.Methods:Synovial tissues were isolated from paws of naïve C57BL/6 mice (n=8), from patients with rheumatoid arthritis (RA), osteoarthritis (OA) and from healthy controls. Synovial fibroblasts were cultured and transfected with GapmeR to silence HOXD10, -D11, and -D13, respectively or with control GapmeR. RNA sequencing was performed on the NovaSeq platform and pathway analysis was done using R packages and web-based tools (GSEA, EnrichR, Cytoscape). HOXD target gene expression was measured by qPCR (n=3-6).Results:To confirm and further analyze the distinctive expression pattern of HOXD genes, we measured their expression in healthy synovial tissues of different joints of human feet and mouse paws. Similar to what we had found in hands, HOXD10, -D11 and -D13 were less abundant in the joints of the first digit of human feet compared to digits II-V (n=3-4 in each joint). Measurements in joints of mouse paws showed lower expression of HoxD10, -D11 and -D13 in distal interphalangeal joints compared to proximal interphalangeal joints and metacarpophalangeal (MCP) joints, respectively. Silencing of HOXD10, -D11 and –D13, affected the expression of 5333, 2217 and 7347 genes, respectively, in cultured RA synovial fibroblasts from human wrists (n=3).There were more transcripts equally regulated by HOXD10 and -D13 (40% of all HOXD10 and 31% of all HOXD13 regulated transcripts), than by HOXD11 and either -D10 or -D13 (18% of all HOXD10 regulated genes and 16% of all HOXD13 regulated genes), suggesting most redundancy between HOXD10 and -D13 (Figure 1). Among genes differentially expressed in SF isolated from MCP II-V versus thumb joints, 19%, 4% and 33% were regulated by HOXD10, -D11 or –D13, respectively, supporting a role for HOXD13 in particular in shaping the joint specific environment. All three HOXD transcription factors regulated genes involved in cell cycle progression, demonstrating dependence of synovial fibroblasts on these HOX genes for cell division. Other enriched pathways were Toll-like receptor and integrin signaling pathways, regulation of unsaturated fatty acid synthesis and autophagy and extra-cellular matrix protein organization. We could confirm several targets of HOXD10, -D11, and –D13 by qPCR, e.g. NR4A1, ROR2, LIF, ATF3.Figure 1.Comparison of the genes which were differentially expressed after HOXD10-11-13 silencingConclusion:The expression of HOXD10, -D11 and –D13 in synovial fibroblasts and tissues strikinglyoverlaps with predilection sites for RA. Silencing experiments suggested that these embryonic HOX transcription factors have a crucial role in regulating fibroblast functions and might shape a joint specific environment that modulates the development and course of RA in specific joints.References:[1]Klein K, et al.

Abstract
Background:Lenabasum is an oral CB2 agonist that attenuates inflammation and fibrosis in SSc animal models and showed clinical benefit with acceptable safety in a Phase 2 trial in dcSSc.Objectives:Test efficacy and safety of lenabasum in a Phase 3 trial in dcSSc.Methods:Subjects ≥18 years old with disease duration ≤ 6 years were randomized 1:1:1 to lenabasum 5 mg, 20 mg, or placebo (PBO), all BID, with stable background immunosuppressant therapy (IST) allowed. The primary efficacy endpoint was ACR CRISS score, and secondary endpoints were ΔmRSS, ΔHAQ-DI, and ΔFVC, all at Week 52 for lenabasum 20 mg vs PBO.Results:363 adults were dosed; 37 (10%) stopped study drug early, with only 1 subject (PBO cohort) stopping due to adverse event (AE). Baseline demographics were similar among groups. Disease duration was ≤ 3 years in 60% and 66%, mean mRSS score was 22.0 and 23.3, and background IST was used by 89% and 84% of lenabasum 20 mg and PBO groups, respectively.Safety results showed serious AEs and severe AEs occurred in 9.2% and 5.8% vs 14.6% and 13.0%, respectively, of lenabasum 20 mg and PBO groups.Efficacy results (Table) demonstrated:Table 1.Primary and secondary efficacy endpoints and post-hoc analyses, Week 52Group, by IST treatmentCohortNΔmRSS, mean (SD)ΔFVC% mean (SD)ΔFVC, mL mean (SD)ΔHAQ-DI mean (SD)ACR CRISS medianmITT population, MMRM primary analysis methodAllPlacebo123-8.1 (7.72)-1.0 (8.68)-51 (317)-0.13 (0.468)0.887Lenabasum 20 mg120-6.7 (6.59)-1.6 (6.91)-78 (265)-0.13 (0.436)0.888Placebo subjects, per protocol completers, LOCFNo ISTPlacebo16-2.3 (9.4)-2.8 (7.4)-97 (244)0.12 (0.34)0.417All ISTPlacebo97-8.9 (7.07)-1.0 (9.2)-43 (330)-0.17 (0.474)0.936MMF, no other ISTPlacebo29-10.7 (8.1)-0.58 (7.1)-37 (235)-0.12 (0.456)0.935MMF ≤ 2 years, no other ISTPlacebo23-11.7 (8.1)-0.3 (6.0)-41 (197)-0.13 (0.495)0.935Non-MMF ≤ 2 yearsPlacebo24-6.7 (6.2)-1.4 (7.87)-52 (281)-0.15 (0.357)0.931Post-hoc comparisons, per protocol completers, LOCFNo ISTPlacebo16-2.3 (9.4)-2.8 (7.4)-97 (244)0.12 (0.34)0.417Lenabasum 20 mg10-6.3 (6.02)-2.3 (5.58)-99 (209)-0.06 (0.498)0.811Established IST1Placebo26-6.1 (5.35)-4.6 (10.11)-170 (350)-0.17 (0.445)0.619Lenabasum 20 mg38-7.4 (5.08)-0.4 (5.70)2-21 (233)3-0.07 (0.357)0.941Established IST, subjects with ILDPlacebo22-5.9 (5.28)-3.7 (5.43)-133 (206)-0.10 (0.372)0.553Lenabasum 20 mg33-7.2 (5.70)-1.0 (10.5)-47 (365)-0.06 (0.391)0.8192 P = 0.0386 two-sample t-test; 3 P = 0.0481 two-sample t-test; other comparisons were not significant• No significant differences were seen in primary and secondary efficacy endpoints.

Abstract
Background:Interstitial lung disease (ILD) is the leading cause of mortality in patients with Systemic Sclerosis (SSc). Forced Vital Capacity (FVC) is a major indicator of severity in SSc ILD. The ELF serum test and its constituent biomarkers (HA, PIIINP and TIMP-1) have shown to correlate with FVC in two large, independent multicentre cohorts of 457 patients, but also showed a correlation with age.Objectives:Here we aimed to investigate the relationship of the ELF biomarkers and age in a large population of healthy controls and to identify a combined clinical and biomarkers model to stratify for risk of ILD progression in a multicentre longitudinal cohort of patients with SSc.Methods:ELF score was measured in sera from 925 healthy controls in one centre and 869 longitudinal samples from 254 SSc patients from 6 centres across 4 European countries. Clinical data were recorded according to EUSTAR Minimal Essential dataset. FVC% change over time was estimated by Mixed-effects modelling. Patients were then divided in two groups: progressors, with a %FVC drop > 3%/year (according to published MCID) and a group of patients with stable or improving FVC. Lasso penalised regression was carried out with biomarkers and the available clinical and demographic variables at patient’s first visit as potential predictors. The resulting linear predictor was used to derive two thresholds, one for optimal sensitivity (rule-out) and one for optimal specificity (rule-in). Patients within thresholds were further selected according to the ratio of TIMP-1: PIIINP (Figure 1).Results:HA was the only ELF biomarker that correlated significantly with age in the healthy control cohort. Therefore, we defined by linear regression a “residual HA” which accounted for age. TIMP1, PIIINP and residual HA were then considered as distinct biomarkers in the analysis of the SSc cohort. 189 SSc patients with 785 time-points had complete datasets and were included in the analysis. Median follow up was 33 months (IQR 18-48). One-hundred and forty patients (74%) were classified as non progressors, 94 (50%) with no change or improving FVC and 46 (24%) with FVC drop <3% year. 49 patients (26%) were classed as progressors (drop of 3%/year or more in FVC, median slope -4.7%/year). Variable selection via Lasso penalised logistic regression resulted in a model with a c-index of 0.69 (95% CI: 0.60-0.78)) and contained age, disease duration (from first non-Raynaud’s symptom), residual HA, anti-centromere antibodies (ACA) status, previous diagnosis of ILD, joint synovitis and history of protein pump inhibitor use. A two-step process was developed using the linear predictor from the model and the ratio of TIMP-1 and PIIINP (Figure 1). The stratification tool increased by nearly two-fold the ability to predict progressors in any 12 months interval (46 to 49% predictive value vs 26% probability) identifying an 82 to 91% negative predictive value for progression.Conclusion:Building on the face and content validity of the biomarkers included in the ELF score, here we identify an easy to assess combined clinical and biomarker model to stratify patients for their risk of ILD progression. Despite its derivation from a large multicentre cohort, independent validation will determine the clinical value of Scleroscore as a stratification tool for risk of progression of SSc ILD.Disclosure of Interests:Michelle Hutchinson: None declared, Giuseppina Abignano: None declared, Jelena Blagojevic: None declared, Silvia Laura Bosello: None declared, Yannick Allanore Grant/research support from: Alpine, Boehringer Ingelheim, Genentech/Roche, Medsenic, and Sanofi, Christopher Denton Consultant of: Corbus, Actelion, GlaxoSmithKline, Bayer, Sanofi, Galapagos, Inventiva, Boehringer Ingelheim, Roche, CSL Behring, Acceleron, Horizon, Arxx Therapeutics, Grant/research support from: Corbus, Actelion, GlaxoSmithKline, Bayer, Sanofi, Galapagos, Inventiva, Boehringer Ingelheim, Roche, CSL Behring, Acceleron, Horizon, Arxx Therapeutics, Oliver Distler Consultant of: Abbvie, Acceleron Pharma, Amgen, AnaMar, Arxx Therapeutics, Baecon Discovery, Blade Therapeutics, Bayer, Boehringer Ingelheim, ChemomAb, Corbus Pharmaceuticals, CSL Behring, Galapagos NV, Glenmark Pharmaceuticals, GSK, Horizon (Curzion) Pharmaceuticals, Inventiva, iQvia, Italfarmaco, iQone, Kymera Therapeutics, Lilly, Medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Novartis, Pfizer, Roche, Sanofi, Serodapharm, Topadur, Target Bioscience and UCB, Grant/research support from: Abbvie, Acceleron Pharma, Amgen, AnaMar, Arxx Therapeutics, Baecon Discovery, Blade Therapeutics, Bayer, Boehringer Ingelheim, ChemomAb, Corbus Pharmaceuticals, CSL Behring, Galapagos NV, Glenmark Pharmaceuticals, GSK, Horizon (Curzion) Pharmaceuticals, Inventiva, iQvia, Italfarmaco, iQone, Kymera Therapeutics, Lilly, Medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Novartis, Pfizer, Roche, Sanofi, Serodapharm, Topadur, Target Bioscience and UCB, Paul Emery Consultant of: Lilly, Abbvie, Roche, Grant/research support from: Lilly, Marco Matucci-Cerinic Consultant of: Chemomab, Lilly, Abbvie, Actelion, Francesco Del Galdo Speakers bureau: Astra-Zeneca, Boehringer Ingelheim, Actelion, Consultant of: Astra-Zeneca, Mitsubishi-Tanabe, Capella Biosciences, Chemomab, Actelion, Boehringer-Ingelheim, Grant/research support from: Capella Biosciences, Chemomab, Kymab, Mitsubishi-Tanabe

Abstract
Systemic sclerosis (SSc) is a severe multi-organ disease with interstitial lung disease (ILD) being the major cause of death. While targeted therapies are emerging, biomarkers for sub-stratifying patients based on individual profiles are lacking. Herein, we investigated how levels of serum metabolites correlated with different stages of SSc and SSc-ILD. Serum samples of patients with SSc without ILD, stable and progressive SSc-ILD as well as of healthy controls (HC) were analysed using liquid targeted tandem mass spectrometry. The best discriminating profile consisted of 4 amino acids (AA) and 3 purine metabolites. L-tyrosine, L-tryptophan, and 1-methyl-adenosine distinguished HC from SSc patients. L-leucine, L-isoleucine, xanthosine, and adenosine monophosphate differentiated between progressing and stable SSc-ILD. In SSc-ILD, both, L-leucine and xanthosine negatively correlated with changes in FVC% predicted. Additionally, xanthosine was negatively correlated with changes in DLco% predicted and positively with the prognostic GAP index. Validation of L-leucine and L-isoleucine by an enzymatic assay confirmed both the sub-stratification of SSc-ILD patients and correlation with lung function and prognosis score. Serum metabolites may have potential as biomarkers for discriminating SSc patients based on the presence and severity of ILD. Confirmation in larger cohorts will be needed to appreciate their value for routine clinical care.

Cardiac involvement is an important cause of hospitalization and mortality in patients with systemic sclerosis (SSc). Advanced echocardiographic measures such as global longitudinal strain (GLS) have already demonstrated to help identifying cardiac involvement and improve risk-stratification in these patients. However, possible sex differences in echocardiographic parameters including GLS have not been explored so far.
Purpose
To compare standard and advanced (GLS) echocardiographic parameters between male and female patients with SSc and evaluate their association with cardiovascular outcomes.
Methods
A total of 408 patients (345 females, 54±14 years old and 63 males 51±13 years old) were included in the study. The study endpoint was all-cause mortality combined with hospitalisations for heart failure, myocardial infarction, coronary interventions, device implantations, arrhythmias, cerebral infarction and peripheral ischemic disease.
Results
Males and females were comparable in terms of cardiovascular risk-factors and comorbidities but showed differences in terms of disease characteristics: greater modified rodnan skin score and higher creatine phosphokinase was observed in males as compared to females, although high NT-proBNP and deteriorated glomerular filtration rate was more prevalent in females. By standard echocardiography, male SSc patients were characterised by greater left ventricular (LV) volumes, but no difference was observed in LV ejection fraction. By advanced echocardiographic analysis, LV GLS was more preserved in female patients (−21% (IQR: −22% to −20%) as compared to males (−20% (IQR −21% to −19%), p<0.001. After median follow-up of 39 months (IQR: 22–66), the combined endpoint occurred in 84 patients, males were affected significantly more frequently as compared to females (20 (32%) vs. 64 (19%), p=0.017). Kaplan-Meier survival analysis showed that impaired LV GLS (based on median value −20%) was associated with higher cumulative rates of all-cause mortality both in males and females with SSc (females: Chi-Square = 80.307 Log Rank <0.001; males: Chi-Square = 4.493 Log Rank = 0.034) (Fig. 1). In univariate cox regression analyses, LV GLS was also significantly associated with the endpoint both in males and females (in males HR: 1.291, 95% CI: 1.033–1.612, p=0.025, in females HR: 1.386, 95% CI: 1.290–1.491, p<0.001).
Conclusions
Our study shows that among patients with SSc, LV GLS is more impaired in males as compared to females but in both groups is associated with higher prevalence of death and cardiovascular hospitalization.

Abstract
Background:In the INBUILD trial in patients with progressive fibrosing ILDs, nintedanib reduced the rate of decline in forced vital capacity (FVC) versus placebo over 52 weeks both in the overall population and in the subgroup with autoimmune disease-related ILDs. Patients continued blinded randomised treatment until the end of the trial.Objectives:Assess the effects of nintedanib on the risks of death, acute exacerbation of ILD or death, and disease progression or death over the whole INBUILD trial in patients with autoimmune disease-related ILDs and a progressive phenotype.Methods:Patients with progressive fibrosing ILDs other than idiopathic pulmonary fibrosis (IPF) were randomised to receive nintedanib 150 mg bid or placebo. Time to i) death, ii) first acute exacerbation of ILD or death, and iii) disease progression (absolute decline in FVC ≥10% predicted) or death, over the whole trial were analysed in patients with autoimmune disease-related ILDs. Incidence rates of adverse events per 100 patient–years were calculated based on events with onset between the first trial drug intake and the last intake plus 28 days. Analyses were descriptive.Results:Of 663 patients, 170 (82 nintedanib, 88 placebo) had autoimmune disease-related ILDs (89 RA-ILD, 39 SSc-ILD, 19 MCTD-ILD, 23 other autoimmune ILDs including Sjogren’s disease-related ILD [n=7], interstitial pneumonia with autoimmune features [n=5] and undifferentiated CTD-ILD [n=3]). Over the whole trial, in the nintedanib and placebo groups, respectively, mean (SD) exposure to drug was 15.4 (7.4) and 16.9 (6.1) months and maximum exposure was 26.0 and 25.2 months; 62 (75.6%) and 68 (77.3%) patients in these groups, respectively, completed the planned observation time. Over the whole trial, in the nintedanib and placebo groups, respectively, 9.8% and 12.5% of patients died, 12.2% and 20.5% of patients had ≥1 acute exacerbation of ILD or died, and 40.2% and 53.4% of patients had disease progression or died (Table). Diarrhoea was the most common adverse event, with incidence rates of 139.2 and 26.3 events per 100 patient–years in the nintedanib and placebo groups, respectively. Adverse events led to treatment discontinuation in 20.7% of patients in the nintedanib group and 13.6% of patients in the placebo group.Conclusion:Data from the INBUILD trial suggest that nintedanib has a clinically meaningful effect on slowing the progression of ILD in patients with progressive fibrosing autoimmune disease-related ILDs, with adverse events that can be tolerated by most patients.Table.Nintedanib (n=82)Placebo (n=88)HR (95% CI)*Death8 (9.8)11 (12.5)0.80 (0.32, 1.98)≥1 acute exacerbation of ILD or death10 (12.2)18 (20.5)0.58 (0.27, 1.27)Disease progression (absolute decline in FVC ≥10% predicted) or death33 (40.2)47 (53.4)0.72 (0.46, 1.13)n (%) with event over the whole trial (mean [SD] exposure: 15.4 [7.4] and 16.9 [6.1] months in nintedanib and placebo groups, respectively). *Based on time to first event.Disclosure of Interests:Eric Matteson Grant/research support from: Pfizer, Consultant of: Boehringer Ingelheim, Gilead, TympoBio, Arena Pharmaceuticals, Speakers bureau: Simply Speaking, Clive Kelly Consultant of: Boehringer Ingelheim, Speakers bureau: Boehringer Ingelheim, Jörg Distler Grant/research support from: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Paid instructor for: Boehringer Ingelheim, Speakers bureau: Boehringer Ingelheim, Anna-Maria Hoffmann-Vold Grant/research support from: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Actelion, Bayer, GlaxoSmithKline, Speakers bureau: Boehringer Ingelheim, Actelion, Roche, James Seibold Shareholder of: BriaCell, Pacific Therapeutics, Consultant of: Atlantic, Blade Therapeutics, Eicos Sciences, Eiger Biopharmaceuticals, Indalo Therapeutics, Mitsubishi Tanabe Pharma, Bayer, Xenikos, Boehringer Ingelheim, Camurus, Corbus Pharmaceuticals, EMD Serono, Speakers bureau: Boehringer Ingelheim, Shikha Mittoo Grant/research support from: Pfizer, Consultant of: Novartis, Abbvie, Pfizer, Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Paul F.

Abstract
Background:RISE-SSc (NCT02283762) was a multicenter Phase IIb trial of riociguat in pts with early (duration ≤18 months) dcSSc and modified Rodnan skin score (mRSS) 10−22 units. Pts were randomized double-blind to placebo or riociguat 0.5–2.5 mg t.i.d. for 52 weeks. The primary endpoint, mRSS change from baseline to Week (Wk) 52, did not reach statistical significance (p=0.08, riociguat vs placebo), but there were favorable trends in some other outcomes.Objectives:To present open-label long-term extension (LTE) results of RISE-SSc.Methods:Pts who completed Wk 52 of double-blind therapy could enter LTE on riociguat. Endpoints included mRSS, adverse events (AEs), and serious AEs (SAEs).Results:Of 60 pts randomized to riociguat and 61 to placebo, 42 (riociguat−riociguat group) and 45 (former placebo group), respectively, entered LTE. At LTE start, mean±SD mRSS was 16.4±3.2 and 16.3±4.2 units, and mean disease duration was 8.9±7.8 and 8.9±5.8 months, in the riociguat−riociguat and former placebo groups, respectively. Other demographics/disease characteristics were also comparable. Median duration of riociguat treatment was 1092 d in riociguat−riociguat pts and 649 d in former placebo pts. Throughout the study, mRSS decreased in both groups (Figure 1). From Wk 52 to last visit, mRSS fell by −3.02±5.51 in riociguat−riociguat patients and −3.96±5.43 in former placebo pts. Rates of mRSS regression (decrease by >5 units and ≥25% from Wk 52 to last visit) and of % declines in mRSS were similar in the two groups (Figure 2). mRSS progression (increase by >5 units and ≥25% from Wk 52 to last visit) occurred in 1 pt (2%) in each group. During the entire study, rescue therapy agents were used in 15 (36%) riociguat−riociguat pts and 17 (38%) former placebo pts. AEs were reported from Wk 52 to last visit in 82 pts (94%): 40 (95%) riociguat−riociguat and 42 (93%) former placebo. Most common AEs overall: nasopharyngitis (24%), gastroesophageal reflux disease (17%), diarrhea (15%), and hypotension (14%). AEs of special interest (dizziness, postural dizziness, or hypotension) occurred in 5 riociguat−riociguat pts (12%) and 4 former placebo pts (9%). SAEs were reported in 21 (24%) pts: 10 (24%) riociguat−riociguat pts and 11 (24%) former placebo pts, with no SAE reported in >1 patient, no SAEs of special interest, and no deaths.Conclusion:During LTE riociguat treatment, mRSS decreased in both groups from Wk 52 onwards and mRSS progression was uncommon. Riociguat had acceptable safety, similar to the main study, with no new safety signal.Acknowledgments:RISE-SSc was jointly funded by Bayer AG and Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA.Disclosure of Interests:Dinesh Khanna Shareholder of: Eicos, Grant/research support from: NIH NIAID, NIH NIAMS, Consultant of: Acceleron, Actelion, Bayer, BMS, Boehringer-Ingelheim, Corbus, Galapagos, Genentech/Roche, GSK, Mitsubishi Tanabi, Sanofi-Aventis/Genzyme, UCB Pharma, Janet Pope Grant/research support from: AbbVie, Bristol-Myers Squibb, Eli Lilly & Company, Merck, Roche, Seattle Genetics, UCB, Consultant of: AbbVie, Actelion, Amgen, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Eicos Sciences, Eli Lilly & Company, Emerald, Gilead Sciences, Inc., Janssen, Merck, Novartis, Pfizer, Roche, Sandoz, Sanofi, UCB, Speakers bureau: UCB, Marco Matucci-Cerinic Grant/research support from: Actelion, MSD, Bristol-Myers Squibb, Speakers bureau: Acetelion, Lilly, Boehringer Ingelheim, Masataka Kuwana Grant/research support from: Acetelion, Consultant of: Acetelion, Bayer, Chugai, Corbus Pharmaceuticals, CSL Behring and Reata Pharmaceuticals.

Abstract
Background:In the SENSCIS trial, nintedanib reduced the progression of SSc-ILD compared with placebo, as shown by a significantly lower rate of decline in forced vital capacity (FVC) over 52 weeks. There was no significant difference between treatment groups in change in modified Rodnan skin score (mRSS) at week 52. An mRSS of 18–25 has been proposed as an upper cut-off to enrich a cohort for skin-progressive patients. Progression of skin fibrosis has been associated with later progression of ILD.Objectives:To assess the effects of nintedanib on the rate of FVC decline and change in mRSS in the SENSCIS trial in subgroups by mRSS <18 and ≥18 at baseline.Methods:Patients with SSc-ILD with onset of first non-Raynaud symptom <7 years before screening and ≥10% fibrosis of the lungs on a high-resolution computed tomography scan were randomised to receive nintedanib or placebo. We analysed the rate of decline in FVC (ml/year) over 52 weeks and the change from baseline in mRSS at week 52 in subgroups by mRSS (<18; ≥18) at baseline.Results:In the nintedanib and placebo groups, respectively, 219/288 (76.0%) and 226/288 (78.5%) patients had mRSS <18 at baseline. Compared with those with mRSS <18, patients with mRSS ≥18 had a lower mean FVC % predicted (68.3% vs 73.7%) and greater proportions were taking mycophenolate at baseline (58.1% vs 45.6%), were anti-topoisomerase I antibody positive (67.4% vs 58.7%) and had diffuse cutaneous SSc (100% vs 37.8%). The mean (SE) annual rate of decline in FVC in the placebo group was numerically greater in patients who had mRSS ≥18 than mRSS <18 at baseline (-131.7 [29.2] mL/year vs -81.4 [15.4] mL/year). The effect of nintedanib vs placebo on reducing the annual rate of decline in FVC was numerically more pronounced in patients with mRSS ≥18 (difference: 88.7 mL/year [95% CI 7.7, 169.8]) than mRSS <18 (difference: 26.4 mL/year (95% CI -16.8, 69.6) at baseline, but statistical testing did not indicate heterogeneity in the treatment effect of nintedanib between subgroups (p=0.18 for treatment-by-time-by-subgroup interaction) (Figure). In the nintedanib and placebo groups, respectively, changes in mRSS at week 52 were -2.2 (0.3) and -2.1 (0.3) (difference -0.1 [95% CI -1.0, 0.7]) in patients with mRSS <18 at baseline and -2.1 (0.7) and -1.6 (0.7) (difference -0.6 [95% CI -2.1, 1.0]) in patients with mRSS ≥18 at baseline (p=0.62 for treatment-by-visit-by-subgroup interaction).Conclusion:In the placebo group of the SENSCIS trial, the rate of decline in FVC over 52 weeks was numerically greater in patients with mRSS ≥18 than <18 at baseline, while reductions in mRSS were similar. A lower rate of FVC decline was observed in patients treated with nintedanib than placebo both in patients with mRSS ≥18 and <18 at baseline.Acknowledgments:The SENSCIS trial was funded by Boehringer IngelheimDisclosure of Interests:Yannick Allanore Grant/research support from: Yannick Allanore has received grants from Inventiva, Roche and Sanofi, Consultant of: Yannick Allanore has received fees from Actelion, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Curzion, Inventiva, Roche, Sanofi, Viginia Steen Grant/research support from: The associated affiliation has received grants/research from Boehringer Ingelheim, Corbus Pharmaceuticals, CSL Behring, Eicos, Galapagos, Immune Tolerance Network, Reata, Consultant of: Virginia Steen has acted as a consultant for Boehringer Ingelheim, Corbus, CSL Behring, Eicos, Forbius, Masataka Kuwana Grant/research support from: Acetelion, Consultant of: Acetelion, Bayer, Chugai, Corbus Pharmaceuticals, CSL Behring and Reata Pharmaceuticals.

SAT0008 INDIVIDUAL FUNCTIONS OF THE HISTONE-ACETYLTRANSFERASES CBP AND P300 IN REGULATING THE INFLAMMATORY RESPONSE BY AFFECTING HISTONE ACETYLATION AND MRNA STABILITY. Ann Rheum Dis 2020.

Abstract
Background:Prolonged TNF-induced H3K27 acetylation (H3K27ac) and increased mRNA stability in rheumatoid arthritis (RA) synovial fibroblasts (SF) are leading to a sustained inflammatory response. Underlying enzymes coordinately regulating these pathways have not been identified so far. The histone acetyltransferases cAMP-response element binding protein binding protein (CBP) and p300 are writers of activating H3K27ac marks and close homologues with widely accepted redundant functions.Objectives:To analyze individual functions of CBP and p300 in regulating the inflammatory response of RA SF.Methods:SF were isolated from patients with RA undergoing joint replacement surgery. The expression of CBP and p300 was silenced by transfection of antisense LNA gapmeRs (12.5 nM). SF were stimulated with TNF (10 ng/ml) for 24h. Actinomycin D (10 µg/ml) was added 4h after TNF-treatment for 2h and 4h (n=3) to test mRNA stability. Transcriptomes were determined by RNA-seq (Illumina NovaSeq 6000, n=6). We mapped raw reads from RNA-seq reference genome using STAR. Counts for genes were obtained using Feature counts. We searched for differential expression genes (DEG) across experimental conditions using general linear models (glm) implemented in ‘edgeR’ package of R. Significantly affected genes (± fold change > 1.5, FDR < 0.05, top 3000 genes included) entered pathway enrichment analysis for Gene Ontology (GO) biological process, and KEGG pathways in DAVID. Changes in the mRNA (n=12-14) and protein expression (n=6-12) were confirmed by quantitative Real-time PCR and ELISA. The levels of activating histone marks H3K27ac and nuclear localization of p50 and p65 were analyzed by Western blotting.Results:DEG revealed that silencing of p300 affected the expression of 6026 and 5138 genes in unstimulated and stimulated SF, respectively. In contrast, only 285 and 1911 genes were affected by CBP silencing in unstimulated and stimulated SF, respectively. In TNF-stimulated SF, pathway enrichment analysis of DEG revealed a key role of CBP in regulating the “type I interferon signaling pathway” (p=2.12x10-6). Both, silencing of CBP and p300 regulated genes enriched in the “TNF signaling pathway” (CBP: p=0.005; p300: p=0.031). In contrast to CBP silencing that had anti-inflammatory effects, silencing of p300 had pro-and anti-inflammatory effects. ELISA experiments suggested that silencing of CBP reduced the secretion of IL6 (p<0.01), CCL2, CXC3L1 (p<0.05), and CXCL12 (p<0.001). Silencing of p300 reduced the secretion of CCL2 (p<0.001) and CXC3L1 (p<0.05) but increased the expression of IL8 (p<0.001) and CXCL2 (p<0.05). Western blotting revealed that neither CBP, nor p300 silencing affected the nuclear expression of the NF-ĸB subunits p65 and p50. Silencing of p300 reduced the levels of H3K27ac by 30% in unstimulated SF, and by 61.4% (p<0.05) in presence of TNF. In addition to regulating H3K27ac, silencing of p300 regulated the expression of TNF-induced cytokines by increasing the mRNA stability of IL8, IL6 and CCL2 mRNA but not of CXCL2. Silencing of CBP reduced H3K27ac by 43.5% only in presence of TNF and did not affect TNF-induced mRNA stability of cytokines. This is in line with the enrichment of the GO biological process “regulation of mRNA stability” (p=2.61x10-8) being enriched only after silencing of p300.Conclusion:Our results suggested that p300 is the major writer for H3K27ac marks in SF. Additionally, p300 regulated cytokine expression by affecting mRNA stability in a target-specific manner. We identified overlapping and distinct functions for CBP and p300 in regulating the inflammatory response of SF.Disclosure of Interests:Monika Krosel: None declared, Marcel Gabathuler: None declared, Kellie Walker: None declared, Matija Tomsic: None declared, Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Caroline Ospelt Consultant of: Consultancy fees from Gilead Sciences., Kerstin Klein: None declared

Abstract
Background:Fibroblast growth factor receptor 3 (FGFR3) is a member of the family of different fibroblast growth factor receptors with several ligands called fibroblast growth factors (FGFs) in humans. Each FGFR has different isoforms resulting from natural alternative splice variants. Upon binding FGF ligands, fibroblast growth factor receptors (FGFRs) trigger various intracellular signaling pathways to regulate important biological processes. Systematic evaluation of FGF/FGFR signaling in the context of SSc has not been performed so far.Objectives:The aim of this study was to characterize FGFR3/FGF9 signaling in the context of fibroblast activation and to evaluate FGFR3 as a potential molecular target for antifibrotic treatment in SSc.Methods:Differential expression profiling of dermal cells from SSc patients and healthy volunteers were performed employing GEArray cDNA microarray. Real-time PCR, Western Blot, immunohistochemistry and immunofluorescence were done in skin tissues and fibroblasts from SSc patients. Selective inhibitors in conjunction with genetic knockdown and knockout strategies were used to target FGFR3 signalingin vitroand in mouse models of SSc: skin fibrosis induced by bleomycin and by overexpression of a constitutively active transforming growth factor receptor 1 (TBR) and tight skin-1 (TSK) mice. Affymetrix gene arrays in dermal fibroblasts from mice with constitutive FGFR3 signaling and mice lacking FGFR3.Results:Expression of FGFR3, specifically the isoform FGFR3IIIb and its ligand FGF9, was significantly upregulated in the dermis and dermal fibroblasts of SSc patients as compared to healthy volunteers. Furthermore, an increase of FGFR3 IIIb/FGF9 expression comparable to that in SSc fibroblasts could also be obtained by stimulating normal healthy dermal fibroblasts with transforming growth factor (TGFβ)in vitroand in mice constitutively overexpressing active TGFβ receptor type I.Transcriptome profiling,in silicoanalysis and functional experiments revealed that FGFR3 synergistigically induces multiple profibrotic pathways including Endothelin-, Interleukin-4- and CTGF-signaling in a CREB-dependent manner. FGFR3 exerts profibrotic effects by modulating phosphorylation of CREB by ERK-, AKT-, CAMK2- and p38-kinases. Activation of FGFR3 in healthy or SSc dermal fibroblasts by stimulation with recombinant FGF9 was sufficient to induce resting fibroblast-to-myofibroblast differentiation along with increased collagen secretion and alpha-SMA production.Genetic knockout of Fgfr3 abrogates myofibroblast differentiationin vitroand ameliorates skin fibrosis in TSK and TBR mice and in bleomycin-induced fibrosis. Further confirming the translational potential of these findings in the preclinical models of SSc, we demonstrate that pharmacological inactivation of FGFR3 by PD173074 could induce the regression of experimental fibrosis invitroand in bleomycin-challenged, TSK and TBR mice.Conclusion:Our findings characterize FGFR3 as an upstream regulator of a network of profibrotic mediators in SSc and thus, we could demonstrate successfully that the targeted inhibition of FGFR3 could inhibit multiple signaling pathwaysin vitroand ameliorated fibrosis in different preclinical models of SSc. These findings may have direct translational implications as FGFR3 inhibitors are currently in development.Disclosure of Interests:Debomita Chakraborty: None declared, Honglin Zhu: None declared, Astrid Juengel: None declared, Lena Summa: None declared, Yi-Nan Li: None declared, Christina Bergmann: None declared, Alexandru-Emil Matei: None declared, Thuong Trinh-Minh: None declared, Chih-Wei Chen: None declared, Clara Dees: None declared, Andreas Ramming: None declared, Georg Schett Speakers bureau: AbbVie, BMS, Celgene, Janssen, Eli Lilly, Novartis, Roche and UCB, Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Jörg Distler Grant/research support from: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Paid instructor for: Boehringer Ingelheim, Speakers bureau: Boehringer Ingelheim

Abstract
Background:Depression, anxiety and distress affect the quality of life of patients with systemic sclerosis (SSc) [1]. The Hospital Anxiety and Depression Scale (HADS) and Sense of Coherence 13-item scale (SOC-13, measuring comprehensibility, manageability and meaningfulness) are screening tools used in patients with different medical conditions. However, their validity, reliability and sensitivity to change in SSc patients has not been evaluated yet.Objectives:To examine the psychometric properties of HADS and its subscales HADS-A and HADS-D (measuring anxiety and depression symptoms, respectively), and unidimensional SOC-13 in a large cohort of Swiss SSc patients.Methods:Consecutive patients fulfilling the ACR/EULAR 2013 classification criteria for SSc who completed the HADS, SOC-13, Short Form-36 Health Survey (SF-36) and Scleroderma Health Assessment Questionnaire (SHAQ) were included in a cross-sectional and longitudinal analysis. Cronbach’s α, split-half reliability and construct validity were measured. Sensitivity to change (Cohen’s d coefficient) was assessed in patients who worsened within 12±3 months, defined as occurrence of any of the following events: decline in forced vital capacity (FVC)≥10%, new diagnosis of interstitial lung disease (ILD) on high-resolution computed tomography (HRCT), progression of known ILD to >20% lung involvement on HRCT (ILD20), new-onset pulmonary hypertension (PH), increase in European Scleroderma Study Group activity index (EScSG-AI) >3 points, new active digital ulcers, increase in modified Rodnan skin score (mRSS) > 7 points.Results:Of 345 patients (aged 59.34±14.17, 82.9% female, 18.8% with diffuse cutaneous SSc, 47.6% anti-centromere Ab-positive, 23.5% anti-Scl-70 Ab-positive, 13% anti-U1RNP Ab-positive and 11.3% anti-RNA polymerase III Ab-positive) 85 participated with a second visit to the sensitivity to change analysis.Internal consistency was excellent for the HADS (Cronbach’s α=0.91; split-half reliability r=0.92), and very good for HADS-A, HADS-D and SOC-13 (Cronbach’s α=0.85-0.89; split-half reliability r=0.86-0.89).Regarding construct validity, all four scales showed a strong to very strong correlation to each other, as well as with the mental components of SF-36 (Spearman’s r=0.63-0.85). There was a moderate to strong correlation with the SHAQ (Spearman’s r=0.45-0.64).Regarding sensitivity to change: HADS-A showed a large to very large effect size (ES) for progression of ILD as assessed on HRCT and increase in EScSG-AI (Cohen’s d=1-1.63), and a very small to small ES for changes in FVC, DU and mRSS (Cohen’s d=0.02-0.45). HADS-D showed a large ES for changes in the ILD20, mRSS and EScSG-AI (Cohen’s d=0.82-1), and moderate ES for changes of FVC, ILD, PH, DU (Cohen’s d=0.1-0.49). SOC-13 showed generally a very small to small EF, except for change in mRSS (Cohen’s d=0.56).Conclusion:The HADS(A/D) and SOC-13 are valid and easy-to-use tools to detect depression, anxiety and distress in SSc. However, their sensitivity to change might be limited by the respective type of organ involvement and its impact on the patients’ psychological wellbeing.References:[1]Legendre C, Allanore Y, Ferrand I, Kahan A.

Abstract
Background:RISE-SSc (NCT02283762) was a multicenter, double-blind, Phase IIb study of riociguat in early dcSSc. Primary endpoint was change in mRSS from baseline to Wk 52.Objectives:Exploratory, descriptive analyses of riociguat target engagement and effects on disease biomarkers in RISE-SSc and their relationship with effects on the primary endpoint. All biomarker p-values are for information only.Methods:Pts with dcSSc (duration ≤18 mo; modified Rodnan skin score [mRSS] 10–22 units) were randomized to riociguat 0.5−2.5 mg tid (n=60) or placebo (n=61). Biomarkers of target engagement (cGMP), inflammation and/or vascular/endothelial function (e.g. high-sensitivity C-reactive protein [hsCRP], soluble platelet endothelial cell adhesion molecule 1 [sPECAM-1], soluble E-selectin, chemokine ligand 4 [CXCL-4]), and fibrosis (e.g. alpha-smooth muscle cell actin [alphaSMA], pro-collagen mRNA expression) were measured in plasma, serum, and skin biopsies at baseline and Wk 14.Results:Mean±SD change from baseline in mRSS was –2.09±5.66 (n=57) with riociguat and –0.77±8.24 (n=52) with placebo (p=0.08). From baseline to Wk 14, plasma cGMP rose by mean (SD) 94% (78%) (n=52) with riociguat and 10% (39%) (n=52) with placebo (nominal p<0.001). Serum sPECAM-1 and CXCL-4 fell with riociguat vs placebo; changes in hsCRP or E-selectin differed little between groups (Fig 1). Pts with higher baseline sPECAM-1 showed larger mRSS reductions with riociguat vs placebo than pts with lower levels (nominal interaction p=0.004). In baseline skin biopsies, 34% and 31% of pts in the riociguat and placebo groups, respectively, had no alphaSMA-positive cells; other pts had +ve cells (alphaSMA counts 0.1–99.5, median 2.5), a potential indicator of higher disease activity. Pts with +ve baseline alphaSMA counts showed a reduction of mRSS with riociguat vs placebo (Fig 2). Skin collagen mRNA expression biomarkers in skin biopsies showed no differences between groups.Conclusion:Primary study endpoint (change in mRSS) was not met. Plasma cGMP rose with riociguat, confirming engagement with the NO-sGC-cGMP pathway. Serum sPECAM-1 (marker of endothelial activation) and CXCL-4 (marker of progressive SSc) fell with riociguat; hsCRP and E-selectin did not. Some serum and skin biomarkers of higher disease activity at baseline were associated with a greater effect of riociguat on skin fibrosis.Acknowledgments:RISE-SSc was jointly funded by Bayer AG and Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA.Disclosure of Interests:Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Frank Kramer Employee of: Bayer AG, Josef Höfler Employee of: Josef Höfler is an employee of Staburo GmbH, Munich, Germany, contracted by Bayer AG to perform the biomarker analyses, Mercedeh Ghadessi Employee of: Bayer AG, Peter Sandner Employee of: Bayer AG, Yannick Allanore Grant/research support from: BMS, Inventiva, Roche, Sanofi, Consultant of: Actelion, Bayer AG, BMS, BI, Christopher Denton Grant/research support from: GlaxoSmithKline, CSL Behring, and Inventiva, Consultant of: Medscape, Roche-Genentech, Actelion, GlaxoSmithKline, Sanofi Aventis, Inventiva, CSL Behring, Boehringer Ingelheim, Corbus Pharmaceuticals, Acceleron, Curzion and Bayer, Masataka Kuwana Grant/research support from: Acetelion, Consultant of: Acetelion, Bayer, Chugai, Corbus Pharmaceuticals, CSL Behring and Reata Pharmaceuticals.

Abstract
Background:Systemic sclerosis-associated interstitial lung disease (SSc-ILD) has traditionally been treated with therapies such as cyclophosphamide, mycophenolate mofetil, and hematopoietic stem cell transplantation. However, these therapies are limited by potential toxicity, as well as duration and magnitude of effect. Clinicians need awareness of emerging therapies in late-stage clinical trials that may address these limitations.Objectives:This study was conducted to determine whether online independent medical education could improve rheumatologists’ and pulmonologists’ knowledge of emerging therapies for the management of SSc-ILD.Methods:Physicians (N = 2,076) participated in a 30-minute, 2-faculty, video-based, online CME with synchronized slides.1The majority of participants were rheumatologists (n = 522) or pulmonologists (n = 557), but the cohort also included clinical immunologists (n = 132) and other physicians with an interest in the topic (n = 865). This study focuses on the 120 rheumatologists and 111 pulmonologists who completed all pre- and post-questions. The effects of the education on knowledge was assessed using a 3-question, repeated pairs, pre-assessment/post-assessment study design. For all questions combined, the chi-square test assessed differences from pre- to post-assessment. P values <.05 are statistically significant. The activity launched on September 17, 2019, and data were collected through November 5, 2019.Results:Overall significant improvements were seen after participation for both rheumatologists (average correct response rate of 55% at pre-assessment vs 75% at post-assessment; P<.001, N=120), and pulmonologists (average correct response rate of 60% at pre-assessment vs 77% at post-assessment; P<.001, N=111). Specifically, significant improvements were observed in clinicians’ knowledge of clinical trial data for emerging SSc-ILD therapies (figure).Figure.Clinicians from APAC (n = 67) and Europe (n = 79) made up the majority of the cohort, and had similar rates of correct responses without significant differences, indicating consistent effects, independent of the region of origin. After participating in the activity, 48% of pulmonologists and rheumatologists had measurable improved confidence related to their knowledge of emerging therapies for patients with SSc-ILD.Despite the increases in knowledge and confidence observed, the rates of correct responses suggest there is still room for improvement; therefore, ongoing education will be needed to reinforce knowledge of the latest data evaluating new therapies for SSc-ILD and what they will mean for future practice.Conclusion:This study demonstrates the success of online, video-based education in improving rheumatologists’ and pulmonologists’ knowledge of the latest clinical data on emerging therapies for SSc-ILD. This could lead to earlier adoption of new, efficacious therapies that may slow disease progression and improve overall outcomes for these patients.References:[1]Distler O, Hoffmann-Vold A-M.

Abstract
Background:Up to now, three groups used single cell RNA sequencing (scRNA-seq) to analyse the synovium in arthritis using different methods and material to measure RNA expression on a single cell level: Ref. 1 used unsorted dissociated synovial cells and a droplet based method; Refs 2 and 3 performed scRNA-seq on sorted cell populations.Objectives:The aim of this study was to perform a meta-analysis of scRNA-seq data of the synovium in arthritis: 1) to define synovial fibroblast (SF) phenotypes, 2) to confirm differences across SF clusters between rheumatoid arthritis (RA) and osteoarthritis (OA) and 3) to analyse joint specific differences between SF phenotypes.Methods:In addition to the available count matrices [1-3], we used unsorted dissociated synovial cells from three patients with undifferentiated arthritis (UA) with a droplet-based method (10x Genomics). We followed a standard protocol [4] to integrate the datasets into a shared space, even in the presence of extensive technical and/or biological differences (“batch-corrected”). SF were selected as previously described (PDPN+,ISLR+,COL1A2+,PTPRC-) [1-3]. We used a minimum log2 FC of 0.25 for average expression of genes in a cluster relative to the average expression in all other clusters combined to define marker genes. R with Seurat, Monocle and clusterProfiler packages were used for scRNA-seq analysis, pseudotime trajectory analysis and pathway enrichement analysis, respectively. Quantitative PCR (qPCR) (n=6-14 per location and disease), immunohistochemistry (IHC) and Krenn synovitis score (n=5-15 per location and disease) were performed according to standard protocols.Results:Data from 29 RA, 3 UA and 6 OA patients were analysed. From a total of 29’448 cells, we identified 14’787 (50%) with a fibroblast phenotype. Of those, we determined 5 subpopulations (Fig. 1): 1)THY1-CD55hifibroblasts with high expression ofMMP1andMMP3(SF1), 2)THY1loCD34+fibroblasts expressing high levels ofPI16(SF2) 3)THY1hifibroblasts expressing high levels of periostin (POSTN) and collagens (e.g.COL1A1, COL3A1) (SF3), 4)THY1hifibroblasts expressingCXCL12(SF4) and 5)THY1lofibroblasts expressingCXCL12,NR4A1andCCL2(SF5). Fig. 2 shows pathway enrichment map of all marker genes; it organizes enriched terms into a network with edges connecting overlapping gene sets. Pseudotime trajectory axis derived from Monocle indicated that SF4 represent a state between SF3 and SF5. Pseudotemporal expression dynamics ofTHY1marked the progression of these three subtypes (Graph 1). SF1 and SF2 were proportionally underrepresented and SF3-5 overrepresented in RA (chi-squared = 37.18, p = 1.65e-07). The expression of POSTN, a signature gene of SF3, was not different between RA and OA tissues, but significantly correlated with the synovitis score (Spearman ρ = 0.55, p=0.02), in particular with pathological changes in the sublining. POSTN expression was higher in hand than in knee synovial tissues (mean ± SD IHC score: hand 8 ±2, knee 5 ±2) and in cultured SF (qPCR: 10-fold difference). Accordingly, SF3 was enriched in hand versus knee synovial tissues in the scRNA-seq dataset (chi-squared = 944.87, p < 2.2e-16).Fig. 1Fig. 2Graph 1Conclusion:In our meta-analysis, we found comparable subtypes of fibroblasts as in the individual analyses [1-3], showing the robustness of cell phenotype identification using scRNA-seq. The different SF phenotypes appear to be plastic cell states rather than fixed cell subtypes, whose development is controlled by an interrelation between pathological changes in the synovium and joint location.References:[1]Stephenson et al.

Abstract
Background:Pathologic activation of fibroblasts is a central feature of fibrotic tissue disease in Systemic Sclerosis (SSc). Although individual key signaling pathways of fibroblast activation such as transforming growth factor β (TGFβ) and WNT/β-catenin signaling have been identified, the consequences of the concomitant upregulation of these pathways and their crosstalk are incompletely characterized. Given the high medical need, the identification of mutual activation and amplification loops of profibrotic signals is essential to identify novel candidates for antifibrotic therapies. XIAP (X-linked inhibitor of apoptosis protein) is a ubiquitously expressed member of the IAP protein family which are implicated in the regulation of various cellular functions and tissue turnover. XIAP was recently described to be implicated in WNT/β-catenin signaling and TGFβ signaling.Objectives:The aim of this study is to characterize the role of XIAP in fibrotic disease.Methods:XIAP-expression was analyzed by qPCR, IF and Western blot. XIAP was targeted pharmacologically and with siRNA. The activation of WNT/β-catenin signaling was assessed by analyses of WNT target genes, by TOPflash/FOPflash luciferase reporter assay and in reporter mice.In vivo,XIAP inhibition was analysed in two different models of fibrosis.Results:The expression of XIAP is increased in the skin of SSc patients compared to matched healthy individuals with a particular prominent expression in fibroblasts. The overexpression of XIAP is more pronounced in SSc patients with diffuse and active skin fibrosis compared to SSc patients with limited and inactive disease. The overexpression of XIAP is also reflected in several experimental fibrosis models: the model of sclerodermatous graft versus host disease, the model of bleomycin induced skin fibrosis and Topoisomerase I induced fibrosis (TopoI) mice. TGFβ induces the expression of XIAP in vitro and in vivo and treatment with the TGFβ1 receptor antagonist SD208 reverses the TGFβ induced expression of XIAP. Inhibition of XIAP with embelin or siRNA reduces the TGFβ induced activation of fibroblasts with reduced collagen release and reduced expression of myofibroblast markers. In addition, XIAP inhibition reverted the activated fibroblast phenotype in SSc fibroblasts with reduced expression of stress fibers and αSMA. The antifibrotic effects of XIAP inhibition occurred in non-toxic doses as demonstrated by MTT and by TUNEL staining. In vivo, inhibition of XIAP reduced skin fibrosis in the models of bleomycin induced skin fibrosis and in TopoI-induced skin and lung fibrosis as demonstrated by analysis of dermal thickening, dermal hydroxyproline content and by analysis of myofibroblast differentiation. Mechanistically, XIAP inhibition reduced the activation of WNT/β-catenin signaling as demonstrated by TOPflash reporter assays and by the analysis of WNT target genes.Conclusion:XIAP is upregulated in SSc fibroblasts and murine SSc models in a TGFβ-dependent manner and promotes fibroblast activation by fostering canonical WNT signaling. Our data suggest that XIAP mediates an amplification loop between TGFβ and WNT/β-catenin signaling. Inhibition of XIAP may thus be a novel approach to target aberrant WNT/β-catenin signaling in fibrotic diseases.Disclosure of Interests:Christina Bergmann: None declared, Ludwig Hallenberger: None declared, Benita Merlevede: None declared, Clara Dees: None declared, Chih-Wei Chen: None declared, Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Georg Schett Speakers bureau: AbbVie, BMS, Celgene, Janssen, Eli Lilly, Novartis, Roche and UCB, Jörg Distler Grant/research support from: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Paid instructor for: Boehringer Ingelheim, Speakers bureau: Boehringer Ingelheim

Abstract
Background:People living with systemic sclerosis (SSc) often lack access to coordinated, specialized care and self-management support from qualified healthcare professionals. Such gaps lead to significant unmet health needs and inability to get preventive services. The Chronic Care Model (CCM) has been used to guide disease management across a wide range of chronic conditions. The CCM often uses e-health technologies to address self-management problems, connect patients with clinicians and reduce patient travel requirements.Objectives:To evaluate current SSc care practice patterns and elicit patient health technology readiness to define relevant aspects and resources needed to improve SSc chronic disease management.Methods:We employed a cross-sectional survey using the 20-item Patient Assessment of Chronic Illness Care (PACIC) instrument to assess how aspects of SSc care align with key components of the CCM.1Six items drawn from the ‘5A’ (ask, advise, agree, assist, and arrange) model of behavioural counselling were included (all 26 items scored on 5-point scale, 1=never to 5=always). Acceptance of health technology was evaluated by adapting and combining questionnaires from Vanhoof2and Halwas3. German and French speaking SSc patients (>18 years) were recruited from university/cantonal hospitals and the Swiss scleroderma patients’ association. Participants completed anonymous paper/online questionnaires. Data were analysed descriptively.Results:Of 101 SSc patients, most were female (76%), spoke German (78%) and had a median age of 60 years (IQR: 50-68). Median disease duration was 8 years (IQR: 5-15), spanning a range of severity (31% limited SSc, 36% diffuse SSc, 3% overlap syndrome). One-quarter (25%) did not know their disease subset.The mean overall PACIC score was relatively low (2.91±0.95) indicating that care was ‘never’ to ‘generally not’ aligned with the CCM. Lowest mean subscale scores related to Follow-up/ Coordination (2.64±1.02), Goal setting (2.68±1.07) and Problem-solving/Contextual Counselling (2.94±1.22). The single items ‘Given a copy of my treatment plan’ (1.99±1.38) and ‘Encouraged to attend programs in the community’ (1.89±1.16) were given the lowest ratings. The ‘5A’ summary score was 2.84±0.97.In terms of technology readiness, 43% completed the survey online. Most participants owned a smartphone (81%), laptop (63%) and/or desktop computer (46%). The overwhelming majority of patients (91%) reported using the Internet in the last year – primarily for communication (e.g. emails, text messages). Participants indicated relatively little experience with e-health applications and participating in SSc online forums or self-help groups.Conclusion:To improve chronic disease management of SSc patients in Switzerland, current care practices warrant reengineering taking CCM components into account. Specific unmet needs relate to self-management support, help patients set individualized goals, and coordinate continuous care. Web-based technologies incorporating user-centred design principles may be a reasonable option for improving care.References:[1]Glasgow, RE, et al.

Abstract
Background:In the SENSCIS trial in patients with SSc-ILD, nintedanib reduced the rate of decline in FVC over 52 weeks vs placebo, with no difference between groups in change in mRSS.Objectives:Analyse correlation between progression of skin fibrosis and progression of SSc-ILD in the SENSCIS trial.Methods:Patients with SSc-ILD were randomised to receive nintedanib or placebo until the last patient reached week 52 but for ≤100 weeks. We calculated Spearman correlation coefficients between FVC (mL) at baseline and change from baseline in mRSS, mRSS at baseline and change from baseline in FVC (mL), and changes from baseline in mRSS and FVC at weeks 52 and 100 in all patients. We analysed the rate of decline in FVC (mL/year) in patients who did and did not have progression of skin fibrosis (relative change from baseline in mRSS >25% and absolute change from baseline >5 points) at week 52.Results:In the nintedanib (n=288) and placebo (n=288) groups, respectively, mean (SD) baseline FVC (mL) was 2459 (736) and 2541 (816) and mRSS was 11.3 (9.2) and 10.9 (8.8); 53.1% and 50.7% had dcSSc;18.4% and 16.0% had progression of mRSS at week 52. No meaningful correlations were observed in analyses between mRSS and FVC (Table). The mean (SE) annual rate of decline in FVC in the placebo group was similar in patients who did and did not have progression of mRSS (-95.2 [27.1] and -91.4 [15.7] mL/year, respectively). The effect of nintedanib vs placebo on reducing the rate of decline in FVC was numerically more pronounced in patients who did not have progression of mRSS vs those who did (difference [95% CI] 44.3 mL/year [0.6, 88.1] vs 24.6 [-53.7, 102.9]), but the interaction p-value (0.66) did not indicate heterogeneity in treatment effect between subgroups.Conclusion:In the SENSCIS trial, the proportion of patients who had progression of skin fibrosis over 52 weeks was low, without significant differences between placebo and nintedanib. No meaningful correlations were observed between skin fibrosis at baseline or progression of skin fibrosis and progression of SSc-ILD. The rate of decline in FVC was similar between patients who did and did not have progression of mRSS. These findings suggest that in the overall patient population in the SENSCIS trial, progression of skin fibrosis and progression of ILD were distinct manifestations of disease progression.Table:FVC at baseline and change from baseline in mRSSmRSS at baseline and change from baseline in FVCChanges from baseline in mRSS and FVCNCorrelation*NCorrelation*NCorrelation*Week 52Nintedanib2470.11 (-0.01, 0.23)241-0.08 (-0.20, 0.05)238-0.07 (-0.19, 0.06)Placebo2540.12 (-0.00, 0.24)257-0.15 (-0.27, -0.03)2520.03 (-0.09, 0.15)Week 100Nintedanib730.21 (-0.02, 0.42)73-0.06 (-0.29, 0.17)700.06 (-0.17, 0.30)Placebo660.28 (0.04, 0.49)730.04 (-0.19, 0.27)66-0.14 (-0.37, 0.10)*Spearman correlation coefficient (95% CI)Disclosure of Interests:Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Kristin Highland Grant/research support from: Boehringer Ingelheim - PI for SENSCIS and SENSCIS-ON trials (paid to my institution), Consultant of: Kristin Highland has acted as a consultant to Boehringer Ingelheim.

Abstract
Background:In previous studies, we showed that in patients with diffuse cutaneous systemic sclerosis (dcSSc), worsening of skin fibrosis predicts later decline in lung function and worse survival. However, in many patients, an improvement of skin fibrosis is the natural course of dcSSc, and many current clinical trials are designed to show improvement of skin fibrosis rather than prevention of skin fibrosis progression.Objectives:To investigate whether an improvement in skin fibrosis is associated with less progression of visceral organ involvement and better overall-survival during follow-up.Methods:We evaluated patients from the European Scleroderma Trials and Research Group (EUSTAR) database with diffuse cutaneous systemic (dcSSc), baseline modified Rodnan skin score (mRSS) ≥7, valid mRSS at 12±3 months after baseline and ≥1 follow-up visit. Regression of skin fibrosis was defined as a decrease in mRSS >5 and ≥25% and progression as increase by the respective numbers from baseline to 12±3 months. Outcomes were pulmonary progression, cardiac progression, intestinal progression, new onset of scleroderma renal crisis and all-cause death using recently specified definitions (1). Associations between skin changes and outcomes were evaluated by Kaplan-Meier analysis and multivariable Cox regression.Results:Of 1257 included patients, 282 (22.4%) showed a regression of skin fibrosis, 883 (70.2%) were categorized as stable patients and 92 (7.3%) showed progression of skin fibrosis at 12±3 months. Median long-term follow-up for organ involvement/death was 4.2 years. Cox regression analyses indicated that skin fibrosis regression had a significantly lower probability of later FVC decline ≥10% than non-regressive (stable and progressive) patients when controlled for baseline mRSS (p=0.013). No significant association of skin fibrosis regression was found with other organ manifestations or all-cause death. Conversely, associations of skin fibrosis progression were found for later FVC decline ≥10% with a more significant p-value (p<0.001, Figure 1), and there was also an association with all cause death (p=0.026).Conclusion:Progression of skin fibrosis is stronger associated with organ changes and all-cause death at follow up than improvement of skin fibrosis. These data suggest a prevention of progression paradigm for clinical practice. They also suggest that clinical trials designed for prevention of skin fibrosis progression are more meaningful for long-term outcome of SSc patients than trials designed to show improvement of skin fibrosisReferences:[1]Progressive skin fibrosis is associated with a decline in lung function and worse survival in patients with diffuse cutaneous systemic sclerosis in the European Scleroderma Trials and Research (EUSTAR) cohort.

Abstract
Background:The heterogeneity of synovial tissues from patients with arthritis could contribute to the interpatient variability in disease course, prognosis and treatment response. Single-cell RNA sequencing (scRNA-seq) permits in-depth analysis of tissue heterogeneity, which could facilitate drug discovery and patient stratification for precision medicine.Objectives:To construct a comprehensive landscape of synovial cell types and molecular pathways in arthritis by integrating our and published scRNA-seq data, generated across different scRNA-seq technologies [Smart-seq2, Drop-seq], cell preparation protocols [dissociated unsorted, sorted cells] and types of arthritis [undifferentiated (UA), rheumatoid arthritis, osteoarthritis].Methods:Synovial tissues were obtained by ultrasound-guided biopsy from patients with UA [not fulfilling the classification criteria for a specific arthritis, n=3]. Biopsies were disintegrated [enzymatic and mechanical disruption] and cell viability assessed with trypan blue. ScRNA-seq libraries [2 per patient] were prepared with 10X Genomics Drop-Seq and sequenced on NovaSeq6000. Bioinformatics analysis of our and published [n=35] datasets1-3was performed using Seurat protocol4with correction for batch effects and filtering low-quality cells. Functional enrichment analysis of marker genes in clusters was done with STRING Protein-Protein networks. Synovitis was assessed with ultrasound and histology.Results:Our tissue disintegration protocol resulted in good cell yield and viability (92%, 72%, 100%). The synovial cellular heterogeneity detected by scRNA-seq reflected the histological findings [Krenn score, pathotype]. These were supported with the ultrasound and clinically assessed disease activity. The integrated analysis of 41 datasets from 38 donors yielded 41845 scRNA-seq cell profiles, 50% contributed by our dataset. An independent analysis of our data and their integration with published data showed that different scRNA-seq methods and protocols can identify all the major synovial cell types and their activation states (Figure 1) with large heterogeneity between donors. We identified a previously undescribed synovial cell population, which was located near the fibroblast cluster, was negative for canonical cell markers, but highly enriched in cell division genes (80% of marker genes). These cells comprised a mixed population of CD34-, podoplanin (PDPN)highor PDPNlowcells that were mostly negative for the sub-lining fibroblast marker THY. Furthermore, they appeared to be highly secretory (extracellular matrix components) and their gene expression profile was inclined towards cell migration, vascular development and insulin growth factor-dependent processes.Figure 1.Heatmap with top 20 cluster gene markers, gene enrichment analysis and UMAP plot of synovial cell clusters.Conclusion:By integrating synovial scRNA-seq data from 41845 cells, we identified a previously undescribed, highly proliferative and secretory synovial cell population in arthritis. We increased the number of known scRNA-seq synovial cell profiles in arthritis by two-fold and demonstrated the robustness of synovial scRNA-seq data outputs across different technologies and protocols. This broadens the current knowledge of synovial tissue heterogeneity and pathology in arthritis.References:[1]Stephenson W. et al. Nat Commun 2017.[2]Mizoguchi F. et al.

Abstract
Background:In systemic sclerosis (SSc) patients with interstitial lung disease (ILD) approximately 30% show progressive ILD. It is unknown whether a progressive ILD period is followed by further lung function decline. In clinical practice, treatment is frequently initiated after observation of lung function decline over 6-12 months and lung function stabilization at follow up is often interpreted as treatment effect.Objectives:Assess the predictive ability of lung function decline over 12 months for further deterioration adjusted for known risk factors for ILD and treatment in two large and well characterized SSc cohorts.Methods:Patients with SSc-ILD by HRCT, fulfilling SSc classification criteria, from the Oslo and Zurich University Hospital were included. The first period with three consecutive annual forced vital capacity (FVC) measurements (i.e. at 0, 12 and 24 months, +/- 3 months) was used. Lung function decline was assessed by absolute changes in FVC% predicted. Moderately progressive ILD was defined as FVC decline of >5-<10% and significantly progressive ILD as FVC decline ≥10% in 12 months. Candidate predictors by experts (including SSc subtype, autoantibodies, disease duration, baseline and FVC decline in the first period, extent of lung and skin (mRSS) fibrosis, CRP, reflux, tendon friction rubs, O2 desaturation, dyspnea) for FVC decline in the second period were tested using logistic regression analysis. Treatment included low dose corticosteroids, mycophenolate mofetil; and other immunosuppressive treatment (cyclophosphamide, Rituximab and Tocilizumab).Results:In total, 240 SSc-ILD patients met the inclusion criteria (table). Of these 69 (29%) SSc-ILD patients showed progressive ILD in the first 12 months period; 34 (14%) with moderate (5-10%) and 35 (15%) with significant FVC decline (≥10%). Independent of FVC changes in the first period, 77 (32%) showed progressive ILD in the second period; 44 (18%) moderate and 33 (14%) significant FVC decline. Only 21 (9%) SSc-ILD patients had two progressive periods, and 115 (48%) were stable in the two 12 month’s periods; all independent of treatment. In multivariable logistic regression, progressive ILD in the first period (moderate, significant or combined FVC decline) was not predictive for progression in the following period. Of all applied risk factors, only mRSS was significantly predictive for further FVC decline, also when adjusted for age, gender and treatment (OR 1.03, 95%CI 1.00-1.08, p=0.035).Conclusion:Decline of FVC in one 12 months period did not predict further ILD progression in the following 12 months independent of treatment. These results have important clinical implications. Firstly, a decline of lung function in one period seems not to be the right indicator for initiating treatment. Secondly, stabilization of lung function under treatment initiated after ILD progression cannot necessarily be interpreted as a treatment response on the individual patient level.Table:First periodBoth periodsSSc-ILD (n=240)ILD progression (n=69)ILD progression (n=21)Stable ILD (n=115)Age, years (SD)48 (14.7)49 (13.8)50 (14.3)46 (15.3)Male, n (%)57 (24)18 (26)5 (24)27 (24)Disease duration yrs, mean (SD)10.2 (11.4)9.8 (10.2)8.8 (11.0)10.8 (12.3)Disease duration <3 years, n (%)68 (28)22 (32)8 (38)29 (25)Diffuse cutaneous SSc, n (%)95 (40)30 (44)11 (52)43 (27)Anti-topoisomerase I Ab, n (%)84 (35)27 (40)9 (43)42 (37)mRSS, mean (SD)10 (9.3)11 (10.2)16 (13.0)8 (8.3)CRPml, mean (SD)3.6 (7.2)3.3 (6.2)4.4 (9.1)3.1 (5.1)GERD, n (%)148 (62)44 (64)15 (74)70 (61)FVC % predicted90 (20.3)90 (21.9)92 (21.7)89 (19.3)DLCO% predicted64 (17.9)64 (16.6)70 (11.3)65 (17.5)Lung fibrosis >20%, n (%)55 (23)16 (23)4 (19)27 (24)Mycophenolate Mofetil, n (%)47 (20)15 (22)5 (24)23 (20)Other immunosuppression, n (%)79 (33)22 (32)9 (43)42 (37)Corticosteroids, n (%)62 (26)18 (26)8 (38)28 (24)Disclosure of Interests:Anna-Maria Hoffmann-Vold Grant/research support from: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Actelion, Bayer, GlaxoSmithKline, Speakers bureau: Boehringer Ingelheim, Actelion, Roche, Håvard Fretheim: None declared, Britta Maurer Grant/research support from: AbbVie, Protagen, Novartis, congress support from Pfizer, Roche, Actelion, and MSD, Speakers bureau: Novartis, Mike Durheim Grant/research support from: BI, Consultant of: BI, Speakers bureau: BI, Øyvind Midtvedt: None declared, Mike O.

AB0553 THE NOCEBO PHENOMENON PARTLY ACCOUNTS FOR DIARRHOEA AMONG PARTICIPANTS IN THE RANDOMIZED PLACEBO-CONTROLLED TRIAL OF NINTEDANIB FOR INTERSTITIAL LUNG DISEASE ASSOCIATED WITH SYSTEMIC SCLEROSIS (SENSCIS).

Abstract
Background:The nocebo phenomenon, the opposite of placebo, defined as unfavourable changes in a patient’s symptoms or condition resulting from negative anticipations to treatment and possibly leading to suboptimal outcomes and non- adherence, is more frequent than previously thought in rheumatology practice[1]. The tyrosine kinase inhibitor nintedanib has shown efficacy for the treatment of systemic sclerosis (SSc)-associated interstitial lung disease in SENSCIS, a recent randomized controlled trial (RCT)[2]. Diarrhoea was the most frequently reported adverse event in SENSCIS.Objectives:To test whether the nocebo phenomenon is involved in the prevalence of diarrhoea as an adverse event in trials with nintedanib.Methods:We compared the incidence of diarrhoea in the placebo arm between SENSCIS and all other placebo controlled RCTs involving >40 SSc patients in each arm, as well as between SENSCIS and all other nintedanib RCTs published so far. We also compared the strength of the warnings for diarrhea (ie times word is mentioned and number of lines devoted to nintedanib related “diarrhoea”) in the informed consent forms (ICFs) of different nintedanib RCTsResults:The mean percentage of patients reporting diarrhoea was 32% in the placebo arm and 76% in the active treatment arm in SENSCIS. These numbers are comparing to a prevalence of only 7% (range 2.3-9.1%) and 9% (range 5.8-14%), respectively of other RCTs in SSc (bosentan, n=2; macitentan, n=2; tocilizumab, n=1). Since the estimated point prevalence of diarrhoea in an SSc cohort similar to SENSCIS would not exceed 15% based on the literature, there was an at least 2-fold increase in the occurrence of diarrhoea in the placebo group during SENSCIS. More importantly, when looking into other nintedanib RCTs (Table 1), we found that patients reporting diarrhoea in the placebo arm were 20% and 18% in cancer and idiopathic pulmonary fibrosis (IPF) trials, respectively, which is almost half than in SENSCIS. Consistent with our hypothesis, the percentage of diarrhoea in the placebo arms of the different nintedanib RCTs increased along with the number of mentions and the number of lines devoted to “diarrhoea” in the respective ICFs.Table 1.Percentage of patients developing diarrhoea in phase III nintedanib RCTs and diarrhoea-related warnings in ICFsPublished RCT(year of publication)Treatment indicationplacebo arm, Nnintedanib arm, N (mg/bid)Adjunctive treatment% DiarrhoeaMentions of ‘diarrhoea’/lines devoted in ICFPlaceboActive treatmentSENSCIS(2019)SSc-ILD288288(150)48% MMF5% MTX31.675.79/11INBUILD(2019)Progressive Fibrosing ILD including SSc-ILD and other CTD-ILDs331332 (150)18% ≥1 from biologics, DMARDs, corticoids23.966.98/10INPULSIS1(2014)IPF204309 (150)21% corticosteroids18.661.53/3INPULSIS2(2014)IPF219329 (150)21% corticosteroids18.363.23/3LUME-Lung 1(2014)Lung cancer659655(200)docetaxel21.842.32/4LUME-Lung 2(2016)Lung cancer360353(200)pemetrexed15.434.94/5LUME-meso phase III(2019)Malignant pleural mesothelioma229229(200)pemetrexed & cisplatin23.053.04/5Conclusion:These results indicate that the nocebo phenomenon is partially involved in the high prevalence of diarrhoea among SSc patients participating in the SENSCIS trial.

Abstract
Background:Timely diagnosis of patients with very early systemic sclerosis (veSSc) is essential for their personalized and optimal management. We hypothesise that changes in serum-based extracellular matrix (ECM) turnover biomarkers are already detectable in patients with veSSc, even before occurrence of specific clinical signs.Objectives:To investigate circulating ECM turnover markers as potential biomarkers for veSSc.Methods:Patients with veSSc, n=42, defined as presence of Raynaud’s syndrome and at least one of puffy fingers, positive antinuclear antibodies or pathological nailfold capillaroscopy, who did not meet any classification criteria for SSc, were compared to healthy controls (HC, n=29). Longitudinal assessment, data and sera collection were conducted by EUSTAR standards. ECM-degradation (BGM, C3M, C4M, C6M) and ECM-formation biomarkers (PRO-C3, PRO-C4, PRO-C5) were measured in serum using ELISA assays. The statistical analyses included Mann-Whitney U, Spearman correlation and ROC analysis. Using Kaplan-Meier plots and univariable Cox regression, we explored if biomarkers can predict progression towards definite SSc (fulfillment of ACR/EULAR criteria or minimum two points increase in the criteria score) during the longitudinal follow-up.Results:Compared to HC, veSSc patients showed a deregulated turnover of type III and IV collagen, with higher degradation (higher C3M, C4M, both p<0.0001 and PRO-C3, p=0.004, Figure 1a, resulting in lower turnover ratios PRO-C3/C3M and PRO-C4/C4M, both p<0.0001). The biglycan degradation biomarker BGM was also higher in veSSc (p=0.006), whereas the degradation biomarker for type VI collagen, C6M, was lower than in HC (p=0.002). In the ROC analysis, biomarkers of type III and IV collagen distinguished between veSSc and HC: C3M, AUC=0.95, p<0.0001; C4M, AUC=0.97, p<0.0001; turnover ratios PRO-C3/C3M, AUC=0.80, p<0.0001; PRO-C4/C4M, AUC=0.97; p<0.0001 (Figure 1b).Median follow up was 4.5 years (range 0.5-7.9 years), mean age was 50±2.2 years, 88% female gender, 24% with puffy fingers, 92% were ANA positive, 64% had an abnormal capillaroscopy, none had organ involvement or skin fibrosis. 14/42 veSSc patients fulfilled the ACR/EULAR classification criteria at follow-up (time to fulfilment of criteria ranged between 0.5 and 6.8 years from inclusion) and in addition, 18/42 veSSc patients gained at least two classification criteria-points. This resulted in 14, respectively 18 progressors for the longitudinal analysis. However, in univariable Cox regression, the baseline levels of the markers did not predict progression over time.Conclusion:ECM turnover is already altered in veSSc patients compared to HC. Biomarkes of type III and IV collagen distinguished between veSSc patients and HC, which may indicate them as potential biomarkers for the detection of veSSc in addition to the established immunological and capillaroscopic criteria.Disclosure of Interests:Rucsandra Dobrota: None declared, Suzana Jordan: None declared, Pernille Juhl Employee of: Nordic Bioscience, Britta Maurer Grant/research support from: AbbVie, Protagen, Novartis, congress support from Pfizer, Roche, Actelion, and MSD, Speakers bureau: Novartis, Mike O.

Abstract
Background:Presence of anti-centromere antibodies (ACA) generally associates with a better prognosis than many other systemic sclerosis (SSc) associated autoantibodies. However, presentation of the disease can be very heterogeneous and prediction of the disease course is challenging. Some older studies suggest a possible association between clinical characteristics and isotypes of ACA in patients with SSc. It is unknown whether ACA can serve as biomarker for future SSc development.Objectives:To evaluate the clinical course of very early SSc and to assess whether ACA isotype levels can identify subjects that will progress to definite SSc.Methods:ACA IgG+ patients with very early SSc (defined as presence of ACA IgG AND Raynaud and/or puffy fingers and/or abnormal nailfold capillaroscopy but not fulfilling ACR 2013 criteria) from five prospective SSc cohorts (Leiden, Zurich, Oslo, Bordeaux, Ghent) were included. Presence and levels of ACA IgG, IgM and IgA were determined at first clinical assessment and clinical course was evaluated annually. Disease progression to definite SSc, which was defined as fulfillment of the ACR 2013 criteria for SSc, and included any development of: digital ulcers (DU), interstitial lung disease (ILD) assessed by high resolution chest tomography, pulmonary arterial hypertension assessed by right heart catheterization, gastro-intestinal involvement, renal crisis or myocardial involvement was determined. ACA response characteristics were compared between very early SSc patients that progressed to definite SSc and those who did not. Logistic regression was performed to determine whether ACA response characteristics can predict progression to definite SSc, with adjustment for age and follow-up duration.Results:In total 92 subjects were included with median follow-up (FU) of 3 years (table 1); 39% progressed to definite SSc, mostly based on the development of skin involvement (77%). Twenty-three percent of patients developed lung involvement, 11% DU, 17% gastro-intestinal involvement and 4% myocardial involvement. Progression on more than one organ system was present in 31% of the very early SSc patients. In the multivariable logistic regression, with adjustment for age and follow-up duration, ACA IgG levels at baseline were significantly associated with progression to definite SSc (OR 3.0 (1.1-8.8)). Likewise, a trend was observed for higher ACA IgM levels (OR 1.8 (0.9-3.5)) in the very early SSc patients progressing to definite SSc (figure 1).Table 1.Baseline characteristics and ACA isotype levels in patients with very early SSc, and between progressors and non-progressors. * p value < 0.05.Progressors(n=35)Non-progressors(n=57)Female, n(%)32 (91)50 (91)Age, mean (SD)56 (14)53 (13)Disease duration since non Raynaud phenomenon, median(IQR) in years3 (0.8-10)2 (0.6-7)Follow-up duration in years, median (IQR)4 (2-6)2 (1-3)*Abnormal Nailfold videocapillaroscopy, n(%)17 (65)27 (60)IgA level [aU/mL], median (IQR)63 (34-120)75 (35-144)IgM level [aU/mL], median (IQR)131 (32-585)79 (18-391)IgG level [U/mL], median (IQR)342 (162-720)195 (93-488)*Conclusion:In this study we illustrate that 39% of the ACA positive very early SSc subjects progress to definite SSc within median 4 years. We identified higher ACA IgG level as a predictive biomarker for progression to definite SSc indicating that it might be a useful biomarker for risk stratification in clinical practice.Disclosure of Interests:Nina van Leeuwen: None declared, Jaap Bakker: None declared, Annette Grummels: None declared, Corrie Wortel: None declared, Suzana Jordan: None declared, Sophie Liem: None declared, Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Anna-Maria Hoffmann-Vold Grant/research support from: Boehringer Ingelheim, Consultant of: Boehringer Ingelheim, Actelion, Bayer, GlaxoSmithKline, Speakers bureau: Boehringer Ingelheim, Actelion, Roche, Karin Melsens: None declared, Vanessa Smith Grant/research support from: The affiliated company received grants from Research Foundation - Flanders (FWO), Belgian Fund for Scientific Research in Rheumatic diseases (FWRO), Boehringer Ingelheim Pharma GmbH & Co and Janssen-Cilag NV, Consultant of: Boehringer-Ingelheim Pharma GmbH & Co, Speakers bureau: Actelion Pharmaceuticals Ltd, Boehringer-Ingelheim Pharma GmbH & Co and UCB Biopharma Sprl, Marie-Elise Truchetet: None declared, Hans Ulrich Scherer Grant/research support from: Bristol Myers Squibb, Sanofi, Pfizer, Speakers bureau: Pfizer, Lilly, Roche, Abbvie, Rene Toes: None declared, Thomas Huizinga Grant/research support from: Ablynx, Bristol-Myers Squibb, Roche, Sanofi, Consultant of: Ablynx, Bristol-Myers Squibb, Roche, Sanofi, Jeska de Vries-Bouwstra: None declared

Abstract
Background:The main clinical associations of anti-PM/Scl in Systemic Sclerosis (SSc) so far reported include calcinosis, myositis and interstitial lung disease (ILD). Nevertheless, data regarding the long-term outcome of ILD in these patients are lacking. A single centre Spanish cohort reported a better functional outcome in 14 SSc-ILD patients anti-Pm/Scl+ as compared to 49 anti-Topo I after a mean follow-up of 7 years (1).Objectives:To analyze the long-term outcome of ILD in a large multicentre EUSTAR study dedicated to anti-Pm/Scl SSc patients.Methods:A case-control study within the EUSTAR cohort collected 165 anti-PM/Scl+ SSc cases and 257 anti-PM/Scl- SSc controls, matched for sex, cutaneous subset, disease duration, and age at onset. Data for ILD at HRCT were available for 162/165 cases and 249/257 controls. Data for pulmonary function tests (PFT) at the baseline (T0), 1 year after diagnosis (T1) and at the last visit (LV) were analyzed.Results:A significantly higher frequency of ILD was reported in anti-Pm/Scl+ cases vs anti-Pm/Scl- controls (62.3% vs 39.4%, p:<0.0001, OR 95%, CI 2.55, 1.70-3.83). Complete PFTs data were available for 81/101 ILD anti-Pm/Scl+ cases and 78/98 anti-Pm/Scl- ILD controls, with similar age at onset and female/male ratio and disease duration at LV (112±81 months vs. 115±64 months, p:0.77). Diffuse cutaneous involvement was less frequent in cases than in controls (27.2% vs. 44.9%, p:0.03).In ILD cases, %pFVC tended to improve from T0 (85.1±18.3) to T1 (89.5±16.5, p:0.045) and to LV (87.9±16.9, p:0.057), while in ILD controls remained stable from T0 (90.4±18.5) to T1 (91.1±16.5, p:0.38) and significantly declined to LV (85.0±18.0, p:0.0002). %pDLCO remained stable from T0 (60.5±16.8) to T1 (60.1±17.6, p:0.87) and to LV (60.4±16.9, p:0.77) in ILD cases, while significantly declined from T0 (67.0±18.9) to T1 (62.7±18.2, p:0.0016) and to LV (59.6±18.4, p<0.0001) in the control group. Mean %pFVC and %pDLCO at the 3 time points were not significantly different between the two groups.Delta %pFVC (LV-T0) was 2.85±11.3 for the anti-Pm/Scl+ group vs -5.42±13.4 in the control group (p:0.0004) with a significant smaller proportion of patients with FVC loss ≥10% from T0 to LV in the anti-PM/Scl group (12.3% vs. 39.7%, p:0.0001). Delta %pDLCO (LV-T0) was -0.13±10.8 for the anti-PM/Scl+ group vs -7.38±14.6 in the control group (p:0.0015), with a significant smaller proportion of patients with DLCO loss ≥10% from T0 to LV in the anti-PM/Scl+ group (13.6% vs. 42.3%, p<0.0001).Conclusion:In this multicenter real-life study, the long-term pulmonary functional outcome in SSc-ILD patients with anti-Pm/Scl positivity seems to be more favorable than in patients without anti-Pm/Scl antibodies.References:[1]Guillen-Del Castillo A, Semin Arthritis Rheum 2014, 44 (3), 331-7.Disclosure of Interests: :Maria Grazia Lazzaroni: None declared, Corrado Campochiaro Speakers bureau: Novartis, Pfizer, Roche, GSK, SOBI, Emiliano Marasco: None declared, Jeska de Vries-Bouwstra: None declared, Franco Franceschini: None declared, Francesco Del Galdo: None declared, Christopher Denton Grant/research support from: GlaxoSmithKline, CSL Behring, and Inventiva, Consultant of: Medscape, Roche-Genentech, Actelion, GlaxoSmithKline, Sanofi Aventis, Inventiva, CSL Behring, Boehringer Ingelheim, Corbus Pharmaceuticals, Acceleron, Curzion and Bayer, Lorenzo Cavagna: None declared, Oliver Distler Grant/research support from: Grants/Research support from Actelion, Bayer, Boehringer Ingelheim, Competitive Drug Development International Ltd. and Mitsubishi Tanabe; he also holds the issued Patent on mir-29 for the treatment of systemic sclerosis (US8247389, EP2331143)., Consultant of: Consultancy fees from Actelion, Acceleron Pharma, AnaMar, Bayer, Baecon Discovery, Blade Therapeutics, Boehringer, CSL Behring, Catenion, ChemomAb, Curzion Pharmaceuticals, Ergonex, Galapagos NV, GSK, Glenmark Pharmaceuticals, Inventiva, Italfarmaco, iQvia, medac, Medscape, Mitsubishi Tanabe Pharma, MSD, Roche, Sanofi and UCB, Speakers bureau: Speaker fees from Actelion, Bayer, Boehringer Ingelheim, Medscape, Pfizer and Roche, Yannick Allanore Grant/research support from: BMS, Inventiva, Roche, Sanofi, Consultant of: Actelion, Bayer AG, BMS, BI, Paolo Airò: None declared
