Introduction Patients with rheumatoid arthritis (RA) who are treated with adalimumab (ADA) are offered a proprietary patient support program (PSP, AbbVie Care®). The main objective of this study was to examine the effectiveness of ADA on RA treatment course over time in the context of PSP utilization. Methods PASSION was a 78-week post-marketing observational study of RA patients with an insufficient response to ≥1 DMARD newly initiating ADA in routine clinical care that was conducted in Europe, Israel, Mexico, Puerto Rico, and Australia. One prior biologic DMARD was allowed. The primary endpoint was percentage of patients achieving the minimal clinically important difference (MCID; improvement of ≥0.22 compared to baseline) in Health Assessment Questionnaire (HAQ) Disability Index (HAQ-DI) at week 78. Additionally, multiple clinical and patient-reported outcomes (PROs) were evaluated over time. Patients were categorized based on their participation in the PSP: ever (PSP users) vs. never (PSP non-users). Safety events were monitored throughout the study. Results Overall, 42.8% of PSP users achieved the MCID in HAQ-DI at week 78 (improvement of at least 0.22 compared to baseline). From 1025 enrolled, 48.7% of patients were PSP users while treated with ADA. The percentage of patients achieving MCID in the HAQ-DI was higher in PSP users vs. PSP non-users (48.1 vs. 37.8%) at week 78 (p

Introduction Adults with moderate-to-severe Crohn’s disease (CD) who responded to risankizumab (RZB) in the phase 2 induction and maintenance study (Feagan, 2017) could enroll in an open-label extension (OLE) study. Interim efficacy and safety of RZB maintenance treatment from the OLE, up to 2 years, are reported. Methods Patients (pts) achieving clinical response (decrease from baseline [BL] in CD Activity Index [CDAI] ≥100) without remission (CDAI Results A total of 65 pts were enrolled (including 4 who were re-induced). Mean (standard deviation) exposure to RZB was 657.2 (190.73) days. At the data cut-off, 14 (21.5%) pts have discontinued the study. Up to wk 48, clinical remission rates were sustained and the proportion of pts with endoscopic remission increased from BL (table 1). Adverse events (AEs) were reported for 58 (89.2%) pts; 18(27.7%) pts had serious AEs. AEs occurring in >10% of pts were nasopharyngitis (26.2%), fatigue (16.9%), arthralgia and worsening CD (15.4% each). Four serious infections in 5 pts were perianal abscess (n=1), Campylobacter (n=1), viral gastroenteritis (n=2), and peritonitis (n=2). No events of tuberculosis, malignancies or deaths occurred. Conclusions In this interim analysis, clinical remission and endoscopic remission were sustained in CD pts receiving long-term RZB treatment. The safety profile of RZB was consistent with previously published data (Feagan, 2017). References Feagan BG, et al. Lancet 2017,29;389(10080):1699–1709. Feagan BG, et al.

Background Adalimumab (ADA) is efficacious and well tolerated in adult patients with ulcerative colitis (UC).1,2 SERENE-UC (NCT02065622) is a study evaluating higher ADA dosing regimens from which induction study results have previously been reported3; here, we report data from the maintenance study. Methods This Phase 3, double-blind, randomised, multicentre study evaluated higher vs. standard ADA dosing regimens for induction and maintenance therapy in adult patients with moderately to severely active UC. Following completion of the induction study at Week 8, all patients were re-randomised 2:2:1 to ADA 40 mg every week (40 EW), ADA 40 mg every other week (40 EOW), or exploratory ADA 40 mg with therapeutic drug monitoring (TDM) regimens, stratified by induction treatment regimen, clinical response status at Week 8, and clinical remission (CRem) status at Week 8 among Week 8 responders. Efficacy endpoints were evaluated in Week 8 responders (ITT-RP) unless indicated differently. The primary efficacy endpoint was proportion of patients achieving CRem (full Mayo Score ≤2 with no subscore >1) at Week 52. The endoscopic component of the Mayo Score was scored via central reading. Non-responder imputation was used for missing values. Comparisons between 40 EW and 40 EOW dosing regimens used the Cochran–Mantel–Haenszel test adjusted for stratification. Safety assessment included a collection of adverse events (AEs), vital signs, and laboratory data. Results Of 852 patients in the Global (ex-Japan) induction study, 757 were re-randomised at Week 8 and 371 were included in the ITT-RP. In the ITT-RP, induction baseline demographics and disease characteristics were generally balanced across the 3 treatment arms; range across arms for mean UC disease duration was 6.2–7.8 years, 6.8–11.7% had prior infliximab use, and 62.5–63.5% were receiving corticosteroids. The overall mean ADA exposure was 252.2 days. The table displays results for efficacy endpoints. The observed safety profile was similar between maintenance treatment arms, including AEs of special interest (generally Conclusion In the Global (ex-Japan) study of SERENE-UC, CRem at Week 52 was numerically higher among Week 8 responders in patients receiving ADA 40 EW compared with 40 EOW maintenance regimens (∆ = 10.5%), but not statistically significant. Higher maintenance treatment with 40 EW was generally safe and well tolerated with a similar safety profile to 40 EOW. No new long-term safety concerns were observed. References

Aim: To evaluate the comparative effectiveness of biologics in inhibiting radiographic progression among rheumatoid arthritis (RA) patients. Materials & methods: Bayesian network meta-analysis of published trials investigating the USA FDA approved biologics treatment in RA patients, using methotrexate (MTX) as the reference comparator. Results: Nine trials met the inclusion criteria for base case analysis. Compared with MTX, most biologics (except golimumab) + MTX had significantly lower rates of radiographic progression at 1 year. Mean difference in radiographic progression rates between MTX monotherapy and biologics + MTX was highest for adalimumab + MTX (-3.8) and lowest for tocilizumab + MTX (-0.7). Inhibition of radiographic progression was sustained. Conclusion: Biologics inhibit radiographic progression in patients with RA at 1 year; however, published evidence beyond 1 year is limited.

Background Low trough levels of the tumour necrosis factor inhibitor, adalimumab (ADL), and anti-ADL antibodies (AAA) were reported to be correlated with lack of response at later time points in patients (pts) with rheumatoid arthritis (RA).1 Objectives To assess the ability of ADL trough levels and clinical assessments at Week 12 to predict clinical remission (REM) after 24 weeks (wks) of treatment with ADL ±methotrexate (MTX) in established RA pts. Methods Data from MTX inadequate responders (MTX-IR) pts with established RA with available measurement of ADL trough levels and clinical assessments at Wks 12 and 24 from several clinical trials were pooled: for pts who received ADL+MTX combination therapy from DE009, DE019, M10–261 and M13–390; for pts who received ADL monotherapy from DE011, M10–261 and M13–390. Efficacy endpoints at Wk 24 were DAS28-CRP Results Based on the cutoffs selected by the predictive model, ADL concentrations at Wk 12 were only slightly predictive for Wk 24 clinical assessment in the ADL monotherapy group, but not in the ADL+MTX group (table 1). However, based on achievement of the specified CDAI, SDAI or DAS28-CRP score at Wk 12 (selected by the model), pts were correctly predicted to reach Wk 24 REM or LDA with an accuracy of 80%–90% and area under the receiver operating characteristic curve (AUC) of 75%–90% (table 2). As an example, pts on ADL monotherapy with DAS28 Conclusions The ADL concentrations at Week 12 selected by the prediction model were weak predictors of disease control at 6 months, especially for pts on ADL+MTX combination therapy. However, using the model-selected cutoffs of composite clinical endpoints at Wk 12, disease control after 6 months of ADL±MTX treatment could be correctly predicted in 70%–80% of pts.

Background It is recognised that early diagnosis and treatment are important in maximising long-term quality of life in patients (pts) with rheumatoid arthritis (RA). Prior biologic disease modifying antirheumatic drug (bDMARD) use has been shown to affect treatment response to further biologic therapy including adalimumab (ADA). Objectives To evaluate the impact of prior bDMARD use on clinical and pt-reported outcomes in pts enrolled in the PASSION study. Methods PASSION was a 78-wk postmarketing, multinational, observational study that assessed the effectiveness of ADA in pts with moderate to severe RA receiving ADA in routine clinical care in the context of participation in the voluntary AbbVie pt support program. Pts with an insufficient response to ≥1 DMARD (1 prior bDMARD was allowed) and newly initiating ADA were enrolled and categorised as bDMARD-naive or bDMARD-experienced. For the present analysis, ADA treatment response was determined by evaluating least squares (LS) mean change from baseline for multiple clinical and pt-reported outcomes (table 1). Missing data for each efficacy endpoint were imputed using last observation carried forward, and differences between groups for efficacy endpoints at wks 24, 52, and 78 were based on ANCOVA models adjusting for baseline and demographic variables (table 1). Additionally, the percentages of pts at each time point (observed population) who achieved HAQ-DI minimal clinically important difference (MCID; improvement from baseline of ≥0.22) were assessed. Results Of 1025 pts included in the intent-to-treat population, 182 were bDMARD-experienced and 843 were bDMARD-naive at baseline. There were no significant differences between groups in sex, race, ethnicity, weight, height, body mass index, TJC28, SJC28, and pain at baseline. However, bDMARD-experienced pts were significantly older, had longer RA duration, and had lower values for HAQ-DI, DAS28(CRP), CDAI, SDAI, PtGA, and PhGA than bDMARD-naive pts at baseline (p Conclusions Among pts with moderate to severe RA that initiated ADA treatment in the PASSION study, bDMARD-naive pts achieved significantly larger improvements from baseline to wk 78 in a variety of clinical and pt-reported outcomes compared with bDMARD-experienced pts. A large proportion of both bDMARD-naive and bDMARD-experienced pts achieved HAQ–DI MCID with ADA treatment.

Background Patients (pt) with Rheumatoid arthritis (RA) who are treated with adalimumab (ADA) are offered a Patient Support Program (PSP) with variety of services. To date, no prospective study has been conducted to analyze the acceptance and the impact of these PSPs on treatment effectiveness and pt satisfaction. Objectives The purpose of this study was to examine the effectiveness of ADA on rheumatoid arthritis (RA) treatment course in the context of PSP participation. Methods PASSION (NCT01383421) was a 78-week (wk) post-marketing observational study of pts with RA receiving ADA in routine clinical care. Pts from the EU, Israel, Mexico, Puerto Rico, and Australia with an insufficient response to ≥1 disease-modifying antirheumatic drug (DMARD) newly initiating ADA (1 prior biologic DMARD was allowed) were enrolled. The primary endpoint was the % of pts achieving the minimal clinically important difference (MCID; improvement of ≥0.22 compared to baseline [BL]) in the Health Assessment Questionnaire Disability Index (HAQ-DI) at wk 78. Non-responder imputation (NRI) was used to account for the missing values. Secondary clinical parameters included % of pts achieving MCID in HAQ-DI at wks 24 and 52 and changes in the 28-joint DAS based on CRP (DAS28(CRP)), Simplified Disease Activity Index (SDAI), and Clinical Disease Activity Index (CDAI) at wks 24, 52, and 78 vs BL. Pts were categorized based on their participation in the PSP: ever (PSP users) vs never (PSP non-users) and outcomes were compared after adjusting for corresponding BL values. Results Overall, the primary endpoint, percentage of pts achieving the MCID for HAQ-DI, was achieved by 72.1% (as observed) and 42.8% (NRI) of pts at week 78 with the percentage of pts achieving the MCID for HAQ-DI significantly higher in PSP users vs PSP non-users (48.1% vs 37.8% [NRI]; P Conclusions The final study results showed that, in pts with moderate to severe RA who initiated ADA, significantly better improvement in functional and clinical outcomes was achieved in the PSP users vs the PSP non-users. Improvements were achieved at early timepoints and continued to increase throughout the study. Acknowledgements AbbVie funded the study and the analysis, and approved the abstract for submission.

Background Obese rheumatoid arthritis (RA) patients (pts) may have higher levels of inflammatory mediators, greater joint swelling and tenderness, and suboptimal response to therapy. Objectives We assessed disease activity and treatment response in obese RA pts, using ultrasonography (US) and clinical measures. Methods This post hoc analysis used observed data from the MUSICA trial1 which evaluated the efficacy of high [20 mg/week (wk)] or low (7.5 mg/wk) doses of methotrexate (MTX) in combination with adalimumab (ADA) for 24 weeks (wks) in RA pts with previous inadequate response to MTX who initiated ADA. Pts were grouped according to body mass index (BMI) at baseline (BL): normal BMI Results Out of 308 pts at BL, 69 pts (22.4%) had BMI Conclusions Among obese RA pts initiating ADA, those on low dosage of concomitant MTX had poorer responses than pts in the normal and overweight categories, as measured clinically and by ultrasound imaging, although this effect was partly overcome by wk 24. Obese RA pts may have an improved clinical benefit if ADA is initiated with high (20 mg/week), rather than low dosage of concomitant MTX. References Kaeley et al. ACR/ARHP 2013 Annual Meeting.

Background In rheumatoid arthritis (RA) patients (pts) receiving corticosteroids (CS) or methotrexate (MTX) with an anti-TNF, such as adalimumab (ADA), the concomitant CS or MTX dose may be reduced if pts respond well or have side-effects. Objectives To assess treatment effectiveness in pts whose MTX or CS oral dose was reduced over 10 years (y) of open label (OL) ADA treatment. Methods This was observed data from OL extensions (OLE) of the PREMIER and DE019 trials. 1,2 In PREMIER, MTX-naive, early RA pts received ADA/MTX/ADA+MTX for 2y, and optional OL ADA for upto 8y. In DE019, biologic-naive, established RA pts received 20 mg ADA+MTX/ 40 mg ADA+MTX/PBO+MTX for 1y and optional OL ADA+MTX for upto 9y. In both OLEs, MTX could be added/adjusted at the investigator9s discretion, and oral CS dose could be tapered in pts who responded. Effectiveness at final visit (FV) was assessed by the numbers of pts achieving TJC68 =0, SJC66 =0, improvement from baseline in HAQ-DI ≥0.5 (HAQ-DI 0.5), ACR20/50/70 criteria and 28-joint disease activity score based on C-reactive protein (DAS28-CRP) Results In PREMIER , by the pt9s FV, out of 375 pts who had any oral CS, 220 (58.7%) were on ongoing CS; 155 (41.3%) had stopped. Among the 375 pts, 32% had a stable CS dose and 26.1% had a CS dose reduction. Dose reduction did not affect the proportion of pts reaching ACR criteria, HAQ-DI 0.5, and DAS28-CRP DE019 , by the pt9s FV, out of 352 pts who received any oral CS, 207 (58.8%) were on ongoing CS and 145 (41.2%) had stopped CS. Among the 352 pts, 141 (40%) had a stable CS dose and 82 pts (23.3%) had a dose reduction. Out of 550 pts on MTX during the study, 497 (90.4%) were receiving MTX, and 53 (9.6%) had stopped by FV; 345/550 pts (62.7%) had stable MTX and 158 (28.7%) had a reduction. Reduction of CS or MTX did not affect the proportion of pts who reached the ACR criteria, HAQ-DI 0.5 and DAS28-CRP Conclusions Overall, effectiveness associated with continuous ADA treatment was not sacrificed in pts in whom concomitant oral CS or/and MTX doses were reduced or discontinued, although many of these pts were likely responding well at the time of taper.

Background Adalimumab (ADA) is a tumor necrosis factor (TNF) inhibitor used for treatment of chronic immune diseases. The safety of ADA treatment in pediatric patients (pts) is particularly important since prolonged treatment for these conditions is often required. Objectives To evaluate the safety of ADA, alone or in combination with concomitant therapy, in pediatric pts with polyarticular juvenile idiopathic arthritis (pJIA), enthesitis-related arthritis (ERA), psoriasis (Ps), and Crohn9s disease (CD) Methods Safety data from 6 clinical trials and their open-label extension studies were analyzed. Pts treated for pJIA (NCT00048542, NCT00775437, and NCT00690573) and ERA (NCT01166282 [interim week-52 data]) received ADA 24 mg/m 2 body surface area every other week (eow) or 20 mg eow ( Results The analysis included 577 pediatric pts, representing 1423.3 PY of ADA exposure (Table). Over 90% of pts across indications reported treatment-emergent AEs. Common AEs were headache (13.8, 46.9, and 23.8 E/100 PY for pJIA and ERA, Ps, and CD, respectively), nasopharyngitis (12.4, 57.6, and 14.1 E/100 PY, respectively), and upper respiratory tract infection (30.1, 24.7, and 14.9 E/100 PY, respectively). The rates of serious AEs (E/100 PY) were 13.4 for pts with pJIA and ERA, 7.4 for pts with Ps, and 32.3 for pts with CD. One death was reported from an accidental fall (pt with Ps). There were no reports of malignancies, demyelinating disorders, cardiovascular events, pulmonary embolism, reactivation of hepatitis B, Stevens-Johnson syndrome, or erythema multiforme. Conclusions The safety profile of ADA in pediatric pts with pJIA, ERA, Ps, or CD was similar across indications, and no new safety signals specific to the pediatric population were identified.

Background Methotrexate (MTX) is used as monotherapy or in combination with other DMARDs in the treatment of patients (pts) with rheumatoid arthritis (RA). Objectives To evaluate the effects of low and high MTX doses in combination with initiation of ADA on patient-reported outcomes (PROs) in MTX-inadequate responders (MTX-IR) with moderate-to-severe RA. Methods MUSICA (NCT01185288) was a randomized, double-blind, controlled trial evaluating the efficacy of two different dosages of MTX, 7.5 or 20 mg/week (wk) in combination with ADA (40 mg every other wk) for 24 wks in MTX-IR RA pts. Pts entering the study had been receiving ≥15 mg/wk MTX for at least 12 wks. At each study visit, from baseline (BL) to wk 24, the following PROs were recorded: quality of sleep, using the Medical Outcomes Sleep (MOS) Index II; Satisfaction with treatment medication, using the Treatment Satisfaction Questionnaire for Medication (TSQM); and sexual impairment due to RA, using a single question of how much did your RA affect sexual functioning over the past 7 days. Last observation carried forward (LOCF) was used to account for missing values. Results 154 pts were enrolled in the 7.5 mg/wk MTX+ADA arm, and 155 pts in the 20 mg/wk MTX+ADA arm. Both arms were similar for BL demographics (mean age 54.8, 25.2% male), disease characteristics (mean disease duration 5.3 years; mean DAS28(CRP) of 5.8). BL values for MOS, TSQM and sexual impairment were similar. At wk 24 after treatment, improvements were observed in all subdomains of the MOS Sleep Index and the TSQM, and Sexual Impairment due to RA (Table). Except for the MOS Sleep Index-Awakened Short of Breath/headache domain, TQSM-Side effects and TQSM-Convenience, the differences from BL were statistically significant. At wk 24, the difference between the scores for the two treatment groups was not statistically significant for any of the subdomains in the MOS Sleep Index or the subdomains in the TSQM, except for Convenience (p=0.023), which was lower for the 20 mg/wk MTX dosage group. At wk 24 after treatment, the difference between the scores between the two treatment groups was not statistically significant for Sexual Impairment. Conclusions Similar to observations in pts with early RA (1), the addition of ADA to MTX in pts with moderate-severe disease and insufficient MTX response, led to improvements in quality of sleep, and satisfaction with treatment medication after 24 wks. Improvements in sexual impairment were also observed. Improvements in all three PROs were observed regardless of the concomitant MTX dosage.

Background Patients (pts) may benefit from the use of a patient support program (PSP) to manage their rheumatoid arthritis (RA). Objectives To assess the impact of PSP utilization on adalimumab (ADA) effectiveness for RA treatment in clinical settings. Methods PASSION (NCT01383421) is a post-marketing observational study to explore and describe the effectiveness of ADA on the course of RA treatment and pt satisfaction over time in the context of utilization of the PSP. The study enrolled pts with moderate to severe RA with an insufficient response to ≥1 disease-modifying antirheumatic drug (DMARD) and initiated ADA at participating sites in the EU, Mexico, Puerto Rico, and Australia. Pts had to be ADA-naive and treated with ≤1 prior biologic DMARD. Pts were prescribed ADA according to the local product label and had an option to utilize the PSP while participating in the study. The PSP comprised “Core elements” (starter pack, call center/hotline, nursing services, educational material, and injection guide; offered in all participating countries) and “Other elements” (eg, refill reminders, email, newsletters, support groups, home delivery, and financial assistance; varied by country). The primary endpoint is the % of pts achieving the minimal clinically important difference (MCID; improvement of ≥0.22) in the Health Assessment Questionnaire Disability Index (HAQ-DI) at week (wk) 78 vs baseline (BL). Secondary clinical parameters include % of pts achieving MCID in HAQ-DI at wks 12, 24, 36, 52, and 64 vs BL and changes in the 28-joint Disease Activity Score (DAS28), Simplified Disease Activity Index (SDAI), and Clinical Disease Activity Index (CDAI). Results Most enrolled pts in this interim analysis (n=852) completed 52 wks of treatment. The mean age at BL was 54.1 y; 76.1% of pts were female, and the mean duration of RA was 7.8 y. Mean BL disease scores were 1.5 for HAQ-DI, 5.3 for DAS28 based on C-reactive protein (CRP), 35.8 for SDAI, and 33.4 for CDAI. Prior biologic DMARD exposure was 17.4%. Overall, 49.9% of enrolled pts utilized the PSP. Improvement in physical functioning was greater at all study time points in pts utilizing the PSP vs those who were non-PSP users, as reflected by mean decreases of 0.61 and 0.46, respectively, in HAQ-DI from BL to wk 52 ( P =0.07). More pts using the PSP achieved an MCID in the HAQ-DI vs non-PSP users (73.8% vs 67.2%) at wk 52 ( P =0.18). Significant changes ( P ≤0.005) from BL to wk 52 were observed for pts using the PSP vs non-PSP users in DAS28(CRP) (−2.88 vs −2.13), SDAI (−30.57 vs −21.65), and CDAI (−26.98 vs −20.75) scores. Study discontinuation rates were significantly ( P =0.003) lower among PSP users vs non-PSP users (20.0% vs 29.0%). Conclusions Interim data showed that, in pts with moderate to severe RA who initiated ADA, better improvement in functional and clinical outcomes was achieved in the PSP users vs the non-PSP users. Improvements were maintained at all time points and continued to increase throughout the study, most likely due to better adherence rates among PSP users.

Background The Juvenile Arthritis Disease Activity Score (JADAS) is increasingly accepted for defining a treat-to-target strategy in patients (pts) with juvenile idiopathic arthritis (JIA)1 Objectives To use JADAS to evaluate clinical disease activity/control, with or without functional control, in pts with polyarticular or polyarticular-course JIA (pJIA), following the initiation of adalimumab (ADA) ± concurrent methotrexate (MTX) treatment. To assess the feasibility of JADAS definition of remission (REM) and minimal disease activity (MDA) as part of a treat-to-target strategy. Methods Data for this post hoc analysis originated from M10-444, an open-label study in pJIA pts 2 to Results Out of 32 pts, 25 (78%) had received prior MTX and 27/32 (84%) received concomitant MTX during the study. At baseline, pts had a mean JADAS10 of 18.8, JADAS27 of 19.0, and DI-CHAQ of 1.2. After 12 wks on open-label ADA, improvements were observed in clinical and functional outcomes. At wks 12 and 24, the mean JADAS10 was 6.2 and 5.3; mean JADAS27 was 6.4 and 5.6; mean DI-CHAQ was 0.7 and 0.7, respectively. No pts were in REM/MDA at baseline; however after 12 and 24 wks, a sizeable proportion achieved disease control (table). After 12 and 24 wks of ADA treatment, the proportions of pts achieving both, disease control and DI-CHAQ Conclusions Addition of open-label ADA treatment resulted in clinically important improvements in clinical and functional outcomes in pts with pJIA. JADAS 10 and -27 gave comparable results. JADAS REM and MDA are achievable targets with ADA treatment. References Consolaro et al, Arth & Rheum. 2012.

Background Patients (pts) with rheumatoid arthritis (RA), who achieve clinical disease remission by treatment with disease-modifying agents may have residual joint inflammation and vascularization, which can be detected by Power Doppler (PD) ultrasonography. The aim of this analysis was to evaluate the proportion of RA pts with PD activity, 24 weeks (wks) after the addition of adalimumab (ADA) to methotrexate (MTX). Methods MUSICA (NCT01185288), a 24 wk double-blind, randomized, controlled trial evaluated the efficacy of 2 different dosages of MTX (7.5 or 20 mg/wk) plus ADA (40 mg every other wk) in RA pts with inadequate response to MTX. For this analysis, the MTX dosage groups were combined. Synovial vascularization was assessed by PD US at 10 joints (bilateral dorsal and volar views of metacarpophalangeal joints 2, 3, 5; dorsal images alone of metatarsophalangeal joint 5 and wrists), at baseline (BL), wks 4, 8, 12, 16, 20 and 24. Images were scored by ultrasound-experienced rheumatologists using a semi-quantitative 4-grade scale. Joint swelling was assessed for the same 10 joints (SJC10). Disease activity was assessed by 28-joint count disease activity score using C-reactive protein (DAS28[CRP]) (remission 26). Pearson9s coefficient (ρ) was used to assess correlation between continuous variables. Results After 24 wks of treatment with ADA +MTX, 44/309 pts (14%) were in DAS28(CRP) remission (mean PD score, 3.3); 18/309 (5.8%) pts were in SDAI remission (mean PD score, 2.7). At wk 24, for the 10 joints selected, 30/44 (68%) of pts in DAS28(CRP) remission had positive PD scores, while only 15 pts (34%) had ≥1 swollen joint, and only 6 pts (13.6%) had ≥1 tender joint. Ten out of 18 (55%) pts in SDAI remission had a positive PD score, while none had swollen/tender joints. A poor correlation (ρ Conclusions In agreement with other studies, residual joint inflammation was detected by PD US in pts in clinical remission; therefore ultrasound can offer additional information to that obtained from clinical disease measures.

Background Control of disease activity in patients with rheumatoid arthritis (RA) has become achievable using synthetic and biologic disease modifying anti-rheumatic drugs, both as monotherapy or in combination. However, residual inflammatory disease can be revealed by sensitive imaging techniques such as ultrasonography in patients with remission of disease activity. Objectives To evaluate ultrasonographic vascularity changes in the joints of RA patients with previous methotrexate (MTX) inadequate-response upon initiation of adalimumab (ADA) combination therapy with two different doses of MTX. Methods MUSICA was a double-blind, randomized, controlled trial evaluating the efficacy of 2 different dosages of MTX (7.5 or 20 mg/wk) in combination with ADA (40 mg every other wk) for 24 wks in RA patients with previous inadequate response to MTX. Dorsal and volar Power Doppler (PD) images of bilateral metacarpophalangeal (MCP) joints 2, 3, 5, and dorsal images alone of metatarsophalangeal joint 5 (MTP5) and wrists were scored by 2 of 4 independent ultrasound-experienced rheumatologists using a semi-quantitative 4-grade scale. Patients with baseline and wk-24 ultrasonographic images were subgrouped based on 28-joint count disease activity score using C-reactive protein (DAS28[CRP] Results After 24-wk treatment of ADA with 7.5 or 20 mg/wk MTX, rapid decreases in mean synovial vascularity were observed regardless of achievement of disease control, with most improvement occurring within the first 4 wks. The wrist had the most baseline PD activity, 1.6 out of 6. Improvements in vascularity were greatest in MCP2 (-0.5), MCP3 (-0.4), and wrist (-0.4) after 24 wks of ADA + MTX treatment. Dorsal and volar PD vascularity incidence and activity were similar in MCP2, but differed in MCP3 and MCP5 where dorsal imaging encompassed most activity. After 24 wks of ADA + MTX, mean vascularity of the bilateral 5-joint composite score was lowest in patients that achieved DAS28 (CRP) Conclusions Upon initiating ADA in MTX inadequate-responders, rapid reduction in joint vascularity was observed in many patients, regardless of MTX dose. Low overall baseline ultrasonographic vascularity values may have partially reflected suppression of inflammation due to prior MTX treatment. Improvements in vascularity in patients were observed irrespective of achieving low disease activity or remission with a numeric trend for lower mean vascularity in patients achieving lower disease activity.

Background Adalimumab (ADA) has been shown to be safe and effective in polyarticular juvenile idiopathic arthritis (pJIA), and is approved for use in moderate to severe pJIA patients (pts) ≥4 years (yrs) in the US, Australia, and Japan, and in the EU for pts ≥2 yrs. Objectives Pts with pJIA are candidates for routine childhood vaccinations, according to the respective national guidelines. This post hoc report describes the observed use of vaccines in pJIA pts receiving ADA in 3 clinical trials and one registry. Methods Pts with active pJIA were enrolled in one of the following trials: M10-444 (ages 2 to Results A summary of all vaccinations is presented in the Table. Among the different types of vaccines, the influenza vaccine was the most frequently administered: 55, 63, 10 and 22 influenza vaccines were administered in DE038, M10-240, M10-444 and P10-262, respectively. In addition, pneumococcal, human papilloma virus, diphtheria, tetanus and/or pertussis, hepatitis A and B, and polio vaccines were administered. 2 pts each received >5 vaccinations in DE038 and M10-240, while 3 pts each in M10-444 and P10-262 received >1 but Conclusions These data support the idea that pJIA pts treated with ADA can be immunized with routine, inactive, preventative vaccines, such as the influenza vaccine. However, not all of the eligible pts were vaccinated on time according to the Centers of Disease Control (CDC) recommendations, and many pts were not vaccinated at all suggesting that physicians may be reluctant to use vaccines in children receiving antirheumatic therapies. Further investigation regarding rheumatologists9 vaccination practices for pts with JIA is warranted.
