Comparative efficacy and safety of JAK inhibitors as monotherapy and in combination with methotrexate in patients with active rheumatoid arthritis: A systematic review and meta-analysis.

BackgroundWe aim to evaluate the efficacy and tolerability of Janus kinase inhibitors (JAKi) as monotherapy and in combination with methotrexate (MTX) in active rheumatoid arthritis (RA).MethodsMedline, EMBASE, and Cochrane Library were systematically searched to identify relevant randomized controlled trials (RCTs). Pooled analysis was conducted using random-effects model, along with the risk difference (RD) and 95% confidence intervals (CIs).ResultsThree RCTs, including 2,290 patients, were included. JAKi (tofacitinib, baricitinib, and filgotinib) plus MTX displayed a higher proportion of patients meeting the American College of Rheumatology (ACR) criteria than JAKi alone at week 52 (ACR20 RD 0.032; 95% CI −0.027 to 0.091; ACR50 RD 0.050; 95% CI 0.003 to 0.097; ACR70 RD 0.056; 95% CI 0.012 to 0.100). Similar results were observed for ACR20/50/70 at week 24. No significant difference was found between two regimens for the proportion of patients achieving Health Assessment Questionnaire disability index (HAQ-DI) improvement ≥ 0.22 at weeks 24 and 52. Regarding low disease activity and remission achievement, JAKi in combination with MTX, contributed higher response rates than JAKi alone at weeks 24 and 52. Compared with JAKi monotherapy, combination therapy had a higher risks of treatment-emergent adverse events (TEAEs) and adverse events (AEs) leading to study discontinuation.ConclusionJAKi combined with MTX demonstrated superiority to JAKi monotherapy in terms of ACR responses, low disease activity and remission achievement. The two regimens presented comparable physical functioning measured by HAQ-DI improvement and similar tolerability, except for high risks of TEAEs and AEs leading to study discontinuation in combination therapy.Systematic Review Registration https://www.crd.york.ac.uk/PROSPERO/, identifier CRD42021288907.

Patient-reported outcomes of upadacitinib versus abatacept in patients with rheumatoid arthritis and an inadequate response to biologic disease-modifying antirheumatic drugs: 12- and 24-week results of a phase 3 trial

BackgroundIn previous clinical trials, patients with active rheumatoid arthritis (RA) treated with upadacitinib (UPA) have improved patient-reported outcomes (PROs). This post hoc analysis of SELECT-CHOICE, a phase 3 clinical trial, evaluated the impact of UPA vs abatacept (ABA) with background conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) on PROs in patients with RA with inadequate response or intolerance to biologic disease-modifying antirheumatic drugs (bDMARD-IR).MethodsPatients in SELECT-CHOICE received UPA (oral 15 mg/day) or ABA (intravenous). PROs evaluated included Patient Global Assessment of Disease Activity (PtGA) by visual analog scale (VAS), patient’s assessment of pain by VAS, Health Assessment Questionnaire Disability Index (HAQ-DI), morning stiffness duration and severity, 36-Item Short Form Health Survey (SF-36), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Work Productivity and Activity Impairment (WPAI), and EQ-5D 5-Level (EQ-5D-5L) index score. Least squares mean (LSM) changes from baseline to weeks 12 and 24 were based on an analysis of covariance model. Proportions of patients reporting improvements ≥ minimal clinically important differences (MCID) were compared using chi-square tests.ResultsData from 612 patients were analyzed (UPA, n=303; ABA, n=309). Mean age was 56 years and mean disease duration was 12 years. One-third received ≥2 prior bDMARDs and 72% received concomitant methotrexate at baseline. At week 12, UPA- vs ABA-treated patients had significantly greater improvements in PtGA, pain, HAQ-DI, morning stiffness severity, EQ-5D-5L, 2/4 WPAI domains, and 3/8 SF-36 domains and Physical Component Summary (PCS) scores (P<0.05); significant differences persisted at week 24 for HAQ-DI, morning stiffness severity, SF-36 PCS and bodily pain domain, and WPAI activity impairment domain. At week 12, significantly more UPA- vs ABA-treated patients reported improvements ≥MCID in HAQ-DI (74% vs 64%) and SF-36 PCS (79% vs 66%) and 4/8 domain scores (P<0.05).ConclusionsAt week 12, UPA vs ABA treatment elicited greater improvements in key domains of physical functioning, pain, and general health and earlier improvements in HAQ-DI. Overall, more UPA- vs ABA-treated patients achieved ≥MCID in most PROs at all timepoints; however, not all differences were statistically significant. These data, however, highlight the faster response to UPA treatment.Trial registrationNCT03086343, March 22, 2017.

Improvement in Patient-Reported Outcomes in Patients with Psoriatic Arthritis Treated with Upadacitinib Versus Placebo or Adalimumab: Results from SELECT-PsA 1

IntroductionThe aim of this work is to assess the effect of upadacitinib versus adalimumab and placebo on patient-reported outcomes (PROs) in psoriatic arthritis (PsA) patients with inadequate responses to ≥ 1 non-biologic disease-modifying anti-rheumatic drugs (non-bDMARD-IR) in SELECT PsA-1.MethodsIn this placebo- and active comparator, phase 3 randomized, controlled trial, patients received daily upadacitinib 15 or 30 mg, placebo, or adalimumab 40 mg every other week through 56 weeks. At week 24, placebo-assigned patients were rerandomized to upadacitinib 15 or 30 mg. PROs included Patient Global Assessment of Disease Activity (PtGA), pain, Health Assessment Questionnaire Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Short Form 36 Health Survey (SF-36), EQ-5D-5L index score, Bath Ankylosing Spondylitis Disease Activity Index, morning stiffness, Self-Assessment of Psoriasis Symptoms, and Work Productivity and Activity Impairment. Mean changes from baseline in PROs, improvements ≥ minimum clinically important differences (MCID), scores ≥ normative values, and sustained clinically meaningful responses were compared between treatment groups.ResultsAt weeks 12 and 24, upadacitinib treatment resulted in improvements from baseline versus placebo across all PROs as well as improvements versus adalimumab in HAQ-DI and SF-36 Physical Component Summary score (nominal p < 0.05). Improvements in PtGA, pain, and HAQ-DI were reported as early as week 2. At week 12, significantly (nominal p < 0.05) more upadacitinib- versus placebo-treated patients reported improvements ≥ MCID across all PROs including seven SF-36 domains. The proportions of upadacitinib-treated patients reporting clinically meaningful improvements at week 12 were similar to or greater than with adalimumab and sustained through week 56. Significantly (nominal p < 0.05) more upadacitinib-treated (both doses) patients reported scores ≥ normative values at week 12 versus placebo, and scores were generally similar to or greater than adalimumab.ConclusionsUpadacitinib treatment provides rapid, sustained, and clinically meaningful improvements in PROs in non-bDMARD-IR patients with PsA.SELECT-PsA 1 ClinicalTrials.gov number, NCT03104400.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40744-021-00379-9.

POS1025 TOFACITINIB TREATMENT IN PATIENTS WITH PSORIATIC ARTHRITIS AND PROBABLE DEPRESSION AND/OR ANXIETY: A POST HOC ANALYSIS OF TWO PHASE 3 CLINICAL TRIALS

Background:Depression and anxiety are highly prevalent in patients (pts) with psoriatic arthritis (PsA),1 with inflammation a key pathogenic feature of depression in these pts.2 Tofacitinib is an oral Janus kinase inhibitor for the treatment of PsA. It acts by modulating immune and inflammatory responses. The link between major depressive disorder/generalised anxiety disorder (MDD/GAD), inflammation and tofacitinib effectiveness has not been fully explored.Objectives:Analyse the prevalence of probable MDD/GAD in pts with PsA initiating tofacitinib treatment and the impact of baseline (BL) probable MDD/GAD status on tofacitinib efficacy in these pts.Methods:This was a post hoc analysis of data from pts who received tofacitinib 5 or 10 mg twice daily (BID), or placebo (PBO), pooled from two Phase 3 trials (12-month OPAL Broaden [NCT01877668];3 6-month OPAL Beyond [NCT01882439]4). Pts with BL probable MDD and/or GAD were identified by a Short Form-36 Health Survey (SF-36) Mental Component Summary score (MCS) ≤38. Pt demographics/BL characteristics and outcomes were stratified by the presence (SF-36 MCS ≤38) or absence (SF-36 MCS &gt;38) of BL probable MDD/GAD. At Months (M)3/6/9/12, changes from BL in SF-36 MCS were evaluated, and efficacy assessed by the proportions of pts who achieved: Psoriatic Arthritis Disease Activity Score (PASDAS) ≤3.2, Health Assessment Questionnaire-Disability Index (HAQ-DI) improvement ≥0.35 and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) improvement ≥4. BL global pain was measured via visual analogue scale.Results:Of the 706 pts included in this analysis, BL probable MDD/GAD was identified in 46.2%, 44.9% and 46.2% of pts in the tofacitinib 5 mg BID (108/234), tofacitinib 10 mg BID (106/236) and PBO (109/236) groups, respectively. BL disease activity was similar across the three treatment groups, independent of probable MDD/GAD status (mean PASDAS: 6.1–6.4 in pts with vs 5.8–6.1 in pts without probable MDD/GAD). In the tofacitinib 5 mg BID group, mean BL scores for HAQ-DI (1.4 vs 1.0), FACIT-F total score (20.5 vs 32.4) and global pain (61.3 vs 51.5) indicated worse disability, fatigue and pain, respectively, for pts with vs without BL probable MDD/GAD. Similar findings were seen in the tofacitinib 10 mg BID and PBO groups. At M3, improvements from BL in SF-36 MCS in pts with probable MDD/GAD were numerically, but not significantly, greater with tofacitinib 5 and 10 mg BID vs PBO, and these changes were largely sustained to M12 (Figure 1a). At M3, numerically greater proportions of pts achieved improvements in PASDAS, HAQ-DI and FACIT-F with tofacitinib 5 or 10 mg BID vs PBO, regardless of BL probable MDD/GAD status (Figure 1b–d). Through M3–12, the proportions of pts who achieved PASDAS ≤3.2 with tofacitinib 5 or 10 mg BID were generally significantly greater in pts without vs with probable MDD/GAD (Figure 1b). At all timepoints, rates of improvement in HAQ-DI with tofacitinib 5 mg BID were numerically greater in pts with vs without probable MDD/GAD, whereas the opposite was true for tofacitinib 10 mg BID (Figure 1c). FACIT-F improvement rates with tofacitinib 10 mg BID were consistently numerically greater in pts with vs without probable MDD/GAD, while findings were mixed for tofacitinib 5 mg BID (Figure 1d).Conclusion:Around 46% of pts with PsA treated with tofacitinib had BL probable MDD/GAD (SF-36 MCS ≤38). Pts with BL probable MDD/GAD treated with tofacitinib had sustained changes in SF-36 MCS. Rates of clinical improvement with tofacitinib were generally greater in pts without vs with probable MDD/GAD, whereas findings for disability and fatigue improvements varied between tofacitinib doses. Further research is required to evaluate the relationship between PsA and depression, to improve treatment targets and the quality of life of pts with PsA.

Yoga improves mitochondrial health and reduces severity of autoimmune inflammatory arthritis: A randomized controlled trial

BackgroundOxidative stress (OS) and mitochondrial alterations have been implicated in the pathogenesis of rheumatoid arthritis (RA). Various environmental triggers like air pollutants, smoking, unhealthy social habits and sedentary lifestyle induce OS, which may compromise mitochondrial integrity. This trial was designed to explore the effect of 8-weeks yoga practice on mitochondrial health and disease severity in an active RA group compared with a usual-care control group. MethodsA total of 70 subjects were randomized into two groups: yoga group and non-yoga group. Mitochondrial health was assessed by calculation of mitochondrial DNA copy number (mtDNA-CN), OS markers, mitochondrial activity, mitochondrial membrane potential (ΔΨm), circadian rhythm markers and transcripts associated with mitochondrial integrity: AMPK, TIMP-1, KLOTHO, SIRT-1, and TFAM. Parameters of disease activity and disability quotient were also assessed by disease activity score – erythrocyte sedimentation rate (DAS28-ESR) and health assessment questionnaire-disability index (HAQ-DI), respectively. ResultsIn yoga group, there was a significant upregulation of mtDNA-CN, mitochondrial activity markers, ΔΨm, and transcripts that maintain mitochondrial integrity after 8-weeks of yoga. There was optimization of OS markers, and circadian rhythm markers post 8-weeks practice of yoga. Yoga group participants showed significant improvements in DAS28-ESR (p < 0.05) and HAQ-DI (p < 0.05) over the non-yoga group. ConclusionAdoption of yoga by RA patients holds the key to enhance mitochondrial health, improve circadian rhythm markers, OS marker regulation, upregulation of transcripts that maintain mitochondrial integrity, reduce disease activity and its associated consequences on health outcome and hence can be beneficial as an adjunct therapy.

Upadacitinib improves patient-reported outcomes in patients with rheumatoid arthritis and inadequate response to conventional synthetic disease-modifying antirheumatic drugs: results from SELECT-NEXT

BackgroundTo evaluate the effect of upadacitinib on patient-reported outcomes (PROs) in patients with RA who had an inadequate response to csDMARDs.MethodsPatients in SELECT-NEXT, a randomised controlled trial, were on a background of csDMARDs and received upadacitinib 15 mg and 30 mg or placebo daily for 12 weeks. PROs included Patient Global Assessment of Disease Activity (PtGA), pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), duration and severity of morning (AM) joint stiffness, Short Form 36 Health Survey (SF-36), and Work Instability Scale for RA (RA-WIS). Least squares mean (LSM) changes were based on mixed-effect repeated measure models. Percentages of patients reporting improvements ≥ minimum clinically important differences (MCIDs) and scores ≥ normative values and number needed to treat (NNT) were determined; group comparisons used chi-square tests.ResultsData from 661 patients were analysed. Compared with placebo, patients receiving upadacitinib reported statistically significant improvements (both doses, P < 0.05) in PtGA, pain, HAQ-DI, FACIT-F, duration and severity of AM stiffness, SF-36 (PCS and 6/8 domains), and RA-WIS at week 12. Significantly, more upadacitinib-treated patients (both doses, P < 0.05) reported improvements ≥ MCID in PtGA, pain, HAQ-DI, FACIT-F, AM stiffness, SF-36 (PCS and 4 or 7/8 domains), and RA-WIS and scores ≥ normative values in HAQ-DI, FACIT-F, and SF-36 (PCS and 4 or 5/8 domains). For most PROs, the incremental NNT with upadacitinib to report clinically meaningful improvement from baseline ranged from 4 to 8 patients.ConclusionsUpadacitinib 15 mg or 30 mg daily for 12 weeks resulted in significant and clinically meaningful improvements in global disease activity, pain, physical function, fatigue, duration and severity of AM stiffness, HRQOL, and work instability among csDMARD-IR patients with RA.Trial registrationClinicaltrials.gov, NCT02675426.

Use of a \u201ccritical difference\u201d statistical criterion improves the predictive utility of the Health Assessment Questionnaire-Disability Index score in patients with rheumatoid arthritis

BackgroundThe Health Assessment Questionnaire-Disability Index (HAQ-DI) is used to assess functional status in rheumatoid arthritis (RA), but the change required for meaningful improvements remains unclear. A minimum clinically important difference (MCID) of 0.22 is frequently used in RA trials. The aim of this study was to determine a statistically defined critical difference for HAQ-DI (HAQ-DI-dcrit) and evaluate its association with therapeutic outcomes.MethodsWe retrospectively analyzed data from adult German patients with RA enrolled in a multicenter observational trial in which they received adalimumab therapy at the decision of the treating clinician during routine clinical care. The HAQ-DI-dcrit, defined as the minimum change that can be reliably discriminated from random long-term variations in patients on stable therapy, was determined by evaluating intra-individual variation in patient scores. Other outcomes of interest included Disease Activity Score-28 joints and patient-reported pain and fatigue.ResultsThe HAQ-DI-dcrit was calculated as an improvement (decrease) from baseline of 0.68 in a discovery cohort (N = 1645) of RA patients on stable therapy and with moderate disease activity (mean DAS28 [standard deviation] of 4.4 [1.6]). In the full patient cohort (N = 2740), 22.1% of patients achieved a HAQ-DI-dcrit improvement at month 6. Compared with patients with a small improvement in HAQ-DI (decrease of ≥0.22 to < 0.68) or no improvement (< 0.22), patients achieving a HAQ-DI-dcrit at month 6 had better therapeutic outcomes at months 12 and 24, including stable functional improvements. Change in pain was the most important predictor of HAQ-DI improvement during the first 6 months of therapy.ConclusionsA HAQ-DI-dcrit of 0.68 is a reliable measure of functional improvement. This measure may be useful in routine clinical care and clinical trials.Trial registrationClinicalTrials.gov NCT01076205. Registered on February 26, 2010 (retrospectively registered).

Tofacitinib Versus Biologic Treatments in Patients With Active Rheumatoid Arthritis Who Have Had an Inadequate Response to Tumor Necrosis Factor Inhibitors: Results From a Network Meta-analysis

PurposeTofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This analysis compared the efficacy and safety of tofacitinib with biologic disease-modifying antirheumatic drugs in patients with RA and a prior inadequate response (IR) to tumor necrosis factor inhibitors (TNFi). MethodsA systematic literature review identified 5 randomized placebo-controlled trials that evaluated tofacitinib or biologic disease-modifying antirheumatic drugs (bDMARDs) against placebo in patient populations with RA with a prior IR to TNFi. The definition of TNFi-IR varied across studies, and included patients with an IR or who had failed treatment with TNFi for any reason. A network meta-analysis was conducted comparing study data with regard to American College of Rheumatology response rates and Health Assessment Questionnaire-Disability Index improvement at weeks 12 and 24, rates of treatment withdrawal due to all causes; adverse events (AEs) and lack of efficacy; and rates of AEs, serious AEs, and serious infections. FindingsThe 5 trials included a total of 2136 patients. Tofacitinib 5 mg twice daily combined with methotrexate was found to have relative risk estimates of American College of Rheumatology responses and change from baseline in Health Assessment Questionnaire-Disability Index score comparable with abatacept, golimumab, rituximab, and tocilizumab combined with conventional synthetic disease-modifying antirheumatic drugs. Withdrawal rates from trials due to all causes and AEs were comparable between treatments, and tofacitinib had a lower rate of withdrawals due to lack of efficacy. Rates of AEs and HAQ-DI were comparable between tofacitinib, other active treatments, and placebo. No serious infections were reported with tofacitinib during the placebo-controlled period (up to week 12) in this study population; rates of serious infection with other active treatments were generally low and similar to placebo. ImplicationsDuring a 24-week period, tofacitinib had efficacy and rates of AEs comparable with currently available bDMARDs in the treatment of patients with RA who had a prior IR to TNFi.

Older age at rheumatoid arthritis onset and comorbidities correlate with less Health Assessment Questionnaire-Disability Index and Clinical Disease Activity Index response to etanercept in the RADIUS 2 registry.

Controversy exists in understanding the effects of age at onset and comorbidities in predicting rheumatoid arthritis (RA) response to biologic therapy. The objective of this study was to investigate the influence of age at onset and number of comorbidities on Health Assessment Questionnaire-Disability Index (HAQ-DI) and Clinical Disease Activity Index (CDAI) responses in active RA patients after 6 months of treatment with etanercept. One thousand eight hundred ninety-nine RA patients were assessed after 6 months of etanercept therapy. Patients met the following inclusion criteria: initiated etanercept, continued therapy for at least 6 months, and were not in CDAI low disease activity (LDA) at baseline (CDAI ≤10.0). Changes in HAQ-DI and CDAI scores over 6 months were analyzed across age of onset quintiles. Multivariate regression models evaluated the independent association between both age at onset and number of comorbidities with change in HAQ-DI/CDAI scores or achieving LDA, while accounting for other covariates. Significant improvements in HAQ-DI and CDAI scores were observed in all age-onset groups, although HAQ-DI improvements were less in older-onset patients. Results of multiple linear regression demonstrated that younger age at onset, higher baseline HAQ-DI/CDAI score, rheumatoid factor positivity, shorter disease duration, and fewer comorbidities at baseline were independently associated with improvement in both HAQ-DI and CDAI scores. Similarly, achieving CDAI LDA after 6 or more months of etanercept was associated with younger age at onset, higher baseline CDAI, shorter disease duration, and fewer comorbidities. These patients with older-onset RA and more comorbidities clinically improved with etanercept, but had lower odds of achieving CDAI LDA. Age of onset and number of comorbidities may be important in determining RA tumor necrosis factor inhibitor response.

Rituximab in patients with rheumatoid arthritis in routine practice (GERINIS): six-year results from a prospective, multicentre, non-interventional study in 2,484 patients

IntroductionThe aim of this study was to evaluate the safety and efficacy of rituximab (RTX) in a large cohort of patients with rheumatoid arthritis in routine care, and to monitor changes in daily practice since the introduction of RTX therapy.MethodsThis was a multicentre, prospective, non-interventional study conducted under routine practice conditions in Germany. Efficacy was evaluated using Disease Activity Score in 28 joints (DAS28) and Health Assessment Questionnaire-Disability Index (HAQ-DI). Safety was assessed by recording adverse drug reactions (ADRs). Physician and patient global efficacy and tolerability assessments were also evaluated.ResultsOverall, 2,484 patients (76.7% female, mean age 56.4 years, mean disease duration 11.7 years) received RTX treatment (22.7% monotherapy). The total observation period was approximately six-years (median follow-up 14.7 months). RTX treatment led to improvements in DAS28 and HAQ-DI that were sustained over multiple courses. DAS28 improvements positively correlated with higher rheumatoid factor levels up to 50 IU/ml. Response and tolerability were rated good/very good by the majority of physicians and patients. Mean treatment intervals were 10.5 and 6.8 months for the first and last 400 enrolled patients, respectively. Infections were the most frequently reported ADRs (9.1%; 11.39/100 patient-years); approximately 1% of patients per course discontinued therapy due to ADRs.ConclusionsProlonged RTX treatment in routine care is associated with good efficacy and tolerability, as measured by conventional parameters and by physicians’ and patients’ global assessments. Rheumatoid factor status served as a distinct and quantitative biomarker of RTX responsiveness. With growing experience, physicians repeated treatments earlier in patients with less severe disease activity.

Golimumab in Patients with Active Rheumatoid Arthritis Despite Methotrexate Therapy: Results Through 2 Years of the GO-FORWARD Study Extension

To assess the longterm efficacy and safety of golimumab in patients with active rheumatoid arthritis (RA) despite methotrexate (MTX) therapy. We randomized 444 RA patients with inadequate response to MTX (3:3:2:2) to placebo + MTX (Group 1), golimumab 100 mg + placebo (Group 2), golimumab 50 mg + MTX (Group 3), or golimumab 100 mg + MTX (Group 4). Subcutaneous golimumab/placebo was injected every 4 weeks. Patients could escape early (Group 1 added golimumab 50 mg, Group 2 added MTX, Group 3 increased golimumab to 100 mg, Group 4 continued 100 mg) based on Week 16 swollen and tender joint counts. From Week 24, Group 1 patients received golimumab 50 mg + MTX. After the Week 52 database lock, patients in the longterm extension received golimumab 50-100 mg ± MTX. Coprimary endpoints [Week 14 American College of Rheumatology (ACR)20, Week 24 Health Assessment Questionnaire Disability Index (HAQ-DI)] and Week 52 findings have been published; 2-year findings (observed data by randomized group, no imputation) are presented. Of 444 randomized patients, 392 continued from Week 52 (Group 1: n = 116, Group 2: n = 116, Group 3: n = 84, Group 4: n = 76). Clinical improvement was maintained through Week 104; ~75% and 72% of patients randomized to golimumab 50 mg + MTX and 100 mg + MTX achieved ACR20 response, respectively. The majority [88% (105/120)] of golimumab + MTX-treated patients with Week 24 HAQ-DI improvement ≥ 0.25 maintained improved physical function through Week 104. Group 1 patients with delayed golimumab treatment exhibited more Week 104 radiographic progression (mean change score = 1.15) than golimumab + MTX-randomized patients (0.52). Incidences of serious infections were 2.24, 4.77, 5.78/100 patient-years of followup for golimumab 50 mg + MTX, 100 mg + placebo, and 100 mg + MTX, respectively. Clinical improvement was maintained and no new safety signals were identified with 2 years of golimumab + MTX. Golimumab efficacy and safety, including serious infections, will continue to be monitored through 5 years (Clinical Trial No. NCT00264550).

Golimumab reduces disease activity of rheumatoid arthritis for 1 year and strongly inhibits radiographic progression in Japanese patients: partial but detailed results of the GO-FORTH and GO-MONO studies

The objective of this study is to evaluate the efficacy of golimumab (GLM) in Japanese patients with active rheumatoid arthritis (RA) for 1 year. Nineteen patients were enrolled; 9 were randomized to the placebo (PBO) + methotrexate (MTX), GLM 50 mg + MTX, or GLM 100 mg + MTX therapy group; and 10 were randomized to the PBO, GLM 50 mg, or GLM 100 mg therapy group. One patient in the GLM 100 mg + MTX therapy group with median values from the GO-FORTH study was added. Data were evaluated by assessing the changes in DAS28-ESR, Health Assessment Questionnaire Disability Index (HAQ-DI), and total Sharp score (TSS) at week 52. Mean changes in DAS28-ESR in the MTX monotherapy, GLM 50 mg + MTX, GLM 100 mg + MTX, PBO, GLM 50 mg, and GLM 100 mg therapy groups were -2.70, -2.57, -2.27, -0.60, -2.53, and -2.53, respectively; the mean improvements in HAQ-DI were 0.188, 0.708, 0.377, 0.188, 1.042, and 0.625, respectively. The mean changes in TSS were 1.63, -0.33, -1.17, 4.25, 1.00, and 1.67, respectively. A significant difference was only observed in the mean TSS change between the PBO + MTX and the GLM 100 mg + MTX groups. However, in terms of mean changes in DAS28-ESR in the combination therapy groups, PBO + MTX therapy seemed to elicit similar results as the GLM 50 mg + MTX and GLM 100 mg + MTX therapies (no significant difference) because all four patients in the PBO + MTX therapy group may have received GLM from week 24 as a crossover. Combined GLM + MTX therapy reduced disease activity and strongly inhibited radiographic disease progression in patients with active RA at week 52.

Structural damages disturb functional improvement in patients with rheumatoid arthritis treated with etanercept

Tumor necrosis factor (TNF) inhibitors have produced improvements in clinical, radiographic, and functional outcomes in rheumatoid arthritis (RA) patients. However, it remains unclear whether factors affecting physical functions remain following TNF therapy. The objective of our study was to assess factors affecting improvement of physical functions and to shed light on relations to disease activity and structural changes in patients with RA treated with etanercept. The study enrolled 208 patients, all of whose composite measures regarding clinical, radiographic, and functional estimation both at 0 and 52 weeks after etanercept therapy were completed. Mean disease duration of 208 patients was 9.6 years, mean Disease Activity Score for 28 joints (DAS28) was 5.4, and mean van der Heijde modified total Sharp score (mTSS) was 94.6. Mean Health Assessment Questionnaire Disability Index (HAQ-DI) improved from 1.4 at 0 weeks to 1.0 at 52 weeks after etanercept therapy, a 31% reduction, which was much less than changes in DAS28 and mTSS. By multivariate analysis, HAQ-DI and mTSS at baseline were significantly correlated HAQ remission. Median HAQ-DI improved in 100 versus 20% of the HAQ-DI ≤0.6 versus ≥2.0 groups, respectively. The mTSS cutoff point at baseline to obtain HAQ remission was 55.5. During etanercept treatment in the mTSS <55.5 versus >55.5 groups, median HAQ-DI improved in 70 versus 39%; remission was achieved in 59 versus 33%; and there was no improvement in14 versus 30%, respectively. HAQ-DI improvement was significantly correlated with that of DAS28 but not of mTSS. In conclusion, higher HAQ and mTSS at baseline inhibits HAQ-DI improvement within 1 year of etanercept treatment, and the cutoff point necessary for mTSS to improve physical functions in patients with RA was 55.5.

Health-related Quality of Life Outcomes of Adalimumab for Patients with Early Rheumatoid Arthritis: Results from a Randomized Multicenter Study

Rheumatoid arthritis (RA) is associated with significant impairments in health-related quality of life (HRQOL). We evaluated patient-reported outcomes including HRQOL outcomes following adalimumab plus methotrexate (MTX) therapy in patients with early RA. PREMIER was a phase III, multicenter, randomized, double-blind, active-comparator clinical trial in early RA. Patients aged ≥ 18 years were randomly assigned to receive adalimumab 40 mg every other week (eow) plus weekly MTX, weekly MTX, or adalimumab 40 mg eow for 104 weeks. American College of Rheumatology (ACR) criteria were used to evaluate clinical efficacy and response. Outcomes were assessed using the Health Assessment Questionnaire Disability Index (HAQ-DI), Short-Form 36 Health Survey (SF-36), Short-Form 6 Dimension (SF-6D), visual analog scale (VAS) assessments of global disease activity (patient's global assessment; PtGA) and pain, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), and Health Utility Index Mark 3 (HUI-3). Of 799 patients enrolled, 268 received adalimumab plus MTX, 257 received MTX monotherapy, and 274 received adalimumab monotherapy. Patients treated with adalimumab plus MTX demonstrated significant baseline to Week 104 improvements in HAQ-DI (p < 0.0001), SF-36 Physical Component Summary (p < 0.0001), 4 SF-36 domains [physical function (p < 0.0001), bodily pain (p <0.0001), vitality (p = 0.0139), role limitations-physical (p = 0.0005)], SF-6D (p = 0.0152), VAS-PtGA (p < 0.0001), VAS-pain (p < 0.0001), FACIT-F (p < 0.0001), and HUI-3 (p = 0.0034) scores versus patients treated with MTX monotherapy. Both SF-6D and HUI-3 were found to be sensitive preference-based measures for assessing the effects of treatment on multidimensional function. No clinically meaningful differences between adalimumab and MTX monotherapy groups were observed for most measures. For each measure, there was significant association between HRQOL improvement and ACR clinical response. Adalimumab plus MTX significantly improved physical functioning and HRQOL in patients with early RA over 2 years of treatment. (ClinicalTrials.gov identifier NCT00195663).

Structural damages disturb functional improvement in patients with rheumatoid arthritis treated with etanercept

Tumor necrosis factor (TNF) inhibitors have produced improvements in clinical, radiographic, and functional outcomes in rheumatoid arthritis (RA) patients. However, it remains unclear whether factors affecting physical functions remain following TNF therapy. The objective of our study was to assess factors affecting improvement of physical functions and to shed light on relations to disease activity and structural changes in patients with RA treated with etanercept. The study enrolled 208 patients, all of whose composite measures regarding clinical, radiographic, and functional estimation both at 0 and 52 weeks after etanercept therapy were completed. Mean disease duration of 208 patients was 9.6 years, mean Disease Activity Score for 28 joints (DAS28) was 5.4, and mean van der Heijde modified total Sharp score (mTSS) was 94.6. Mean Health Assessment Questionnaire Disability Index (HAQ-DI) improved from 1.4 at 0 weeks to 1.0 at 52 weeks after etanercept therapy, a 31% reduction, which was much less than changes in DAS28 and mTSS. By multivariate analysis, HAQ-DI and mTSS at baseline were significantly correlated HAQ remission. Median HAQ-DI improved in 100 versus 20% of the HAQ-DI ≤ 0.6 versus ≥ 2.0 groups, respectively. The mTSS cutoff point at baseline to obtain HAQ remission was 55.5. During etanercept treatment in the mTSS <55.5 versus >55.5 groups, median HAQ-DI improved in 70 versus 39%; remission was achieved in 59 versus 33%; and there was no improvement in 14 versus 30%, respectively. HAQ-DI improvement was significantly correlated with that of DAS28 but not of mTSS. In conclusion, higher HAQ and mTSS at baseline inhibits HAQ-DI improvement within 1 year of etanercept treatment, and the cutoff point necessary for mTSS to improve physical functions in patients with RA was 55.5.

Minimally Important Difference of Health Assessment Questionnaire in Psoriatic Arthritis: Relating Thresholds of Improvement in Functional Ability to Patient-rated Importance and Satisfaction

To evaluate changes in function as measured by Health Assessment Questionnaire Disability Index (HAQ-DI) and the meaningfulness of the changes, in importance and satisfaction, in patients with psoriatic arthritis (PsA). HAQ-DI was assessed at baseline and at Weeks 4, 12, and 24 in a randomized double-blind study of 205 patients with active PsA receiving etanercept 25 mg twice weekly or placebo. Concurrently, patients rated the importance of and satisfaction with their change in function on a 7-point scale (1 = not at all important/satisfied; 7 = extremely important/satisfied). Mean HAQ-DI improvement corresponding to ratings of minimally (2-3) or very (6-7) important or satisfied was determined using a posthoc linear mixed-model analysis. Patient importance ratings were used as an anchor to estimate minimally important difference (MID) for HAQ-DI; distribution-based estimates were also calculated. A total of 161 patients (69 placebo; 92 etanercept) had ≥ 1 HAQ-DI scores showing improvement from baseline and a corresponding importance or satisfaction rating. HAQ-DI improvements corresponding to importance scale ratings of 2 or 3 were 0.335 (95% CI 0.214, 0.455) and 0.360 (95% CI 0.263, 0.456), respectively, suggesting an MID of about 0.35. HAQ-DI improvements corresponding to satisfaction scale ratings of 2 and 3 were 0.293 (95% CI 0.230, 0.357) and 0.360 (95% CI 0.307, 0.413). For a given change in HAQ-DI, nearly two-thirds of patients indicated a lower rating for satisfaction than for importance. This trial was registered in the ClinicalTrials.gov registry (NCT00317499). Our study suggests the MID for HAQ-DI in PsA is about 0.35. The results may also provide insight into patient satisfaction with changes in function and expectations for therapy.
