Characteristics, clinical outcomes and patient-reported outcomes of patients with ulcerative colitis receiving tofacitinib: a real-world survey in the United States and five European countries.

BACKGROUND: To describe variations in treatment patterns, clinical outcomes, patient-reported outcomes (PRO), and physician and patient satisfaction in patients with moderate-to-severe ulcerative colitis (UC) treated with tofacitinib in a real-world setting. METHODS: Data were drawn from the Adelphi UC Disease Specific Programme™, a point-in-time survey of physicians and their consulting patients in the US and Europe. For inclusion in this analysis, gastroenterologists completed medical record forms for the next seven consecutive consulting patients with confirmed UC, plus a further two patient record forms for patients treated with tofacitinib. Those same patients then completed a patient-reported questionnaire. RESULTS: Gastroenterologists (n = 340) provided data for 2049 patients with UC, including 642 patients receiving tofacitinib. Physicians' most frequent reason for choosing tofacitinib was overall efficacy (71.3% of patients). The proportion of patients in remission increased with length of treatment, from 13.7% at [0, 4) weeks to 68.3% at [52+] weeks. Both physicians and patients reported that the Mayo components of stool frequency and blood in stool were reduced with time on treatment. Improvement in symptoms (bloody diarrhea, abdominal pain/cramps, urgency, rectal bleeding, fatigue/tiredness) was reported in the first weeks of treatment, and increased with time. At week [52+], mean score reductions from treatment initiation to current in overall symptom severity, pain, and fatigue were 2.2 (to a current mean score of 1.1), 2.2 (to 0.9), and 2.1 (to 1.0), respectively. Comparing patients at weeks [0, 4) and [52+] (all PROs, p < 0.0001), the increase in EQ-5D-5L index total score was 0.29 points and in SIBDQ total score was 20.5 points; percent reductions in WPAI absenteeism was 34.4%, presenteeism 26.8%, overall work impairment 40.9% and activity impairment was 28.3%. These changes reached the thresholds for minimally clinically important differences. The majority of physicians (91.9%) and patients (93.5%) were satisfied with tofacitinib at week [52+]. CONCLUSION: Patients with moderate-to-severe UC treated with tofacitinib show considerable improvement in symptoms and quality of life from tofacitinib initiation to one year and beyond, with high rates of remission. Physicians and patients report satisfaction with UC control at recommended doses in a mostly biologic experienced population.

Experience with Tofacitinib in Patients with Ulcerative Colitis: Data from a United States Claims Database.

BACKGROUND: Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). AIMS: To evaluate real-world data in US patients with UC receiving tofacitinib. METHODS: Characteristics and outcomes of patients with UC initiating tofacitinib between 2018 and 2019 were assessed using data from the IBM® MarketScan® claims database. The index date was the first tofacitinib claim; pre- and post-index periods were 12 months. Outcomes included tofacitinib adherence/persistence, oral corticosteroid (OCS) use, and healthcare resource utilization (HCRU) and costs. RESULTS: Of 276 patients with UC who initiated tofacitinib, 68 (24.6%) were bio-naïve, and 208 (75.4%) bio-experienced. At month 12, overall median tofacitinib adherence (proportion of days covered) was 0.82 (mean 0.68); 43.8% of patients discontinued tofacitinib (90-day gap). Of patients receiving OCS during the post-index 16-week tapering period, 40.4% discontinued OCS up to 12 months post-index. OCS use decreased in patients continuing tofacitinib versus those discontinuing tofacitinib (29.7% vs 59.5%, respectively). Reductions in all-cause and UC-related outpatient visits were observed for bio-naïve (- 1.34 and - 0.88, respectively) and bio-experienced (- 4.72 and - 5.16, respectively) patients, post-index. Decreased UC-related costs per year were observed for bio-experienced patients (difference in post-index vs pre-index, - US$12,448; driven by changes in pharmacy costs), but not for bio-naïve patients (US$47,152). CONCLUSIONS: In this real-world analysis in a mostly bio-experienced population, the majority of US patients with UC initiating tofacitinib remained on therapy at 12 months, and OCS use was reduced with tofacitinib treatment. HCRU (all patients) and UC-related costs were reduced in bio-experienced patients. The majority of patients with ulcerative colitis starting tofacitinib in this real-world study continued therapy at 12 months; there was a reduction in the use of steroids, and a decrease in healthcare resournce utilization and costs.

Incidence and prevalence of psoriatic arthritis in patients with psoriasis stratified by psoriasis disease severity: Retrospective analysis of an electronic health records database in the United States.

BACKGROUND: Among patients in the United States with psoriasis (PsO), limited data exist on the incidence and prevalence of psoriatic arthritis (PsA) based on disease severity. OBJECTIVE: To assess the incidence, prevalence, and predictors of PsA among patients with PsO stratified by PsO severity using treatment type. METHODS: Incidence of PsA per 100 PsO patient-years (PY) and prevalence were assessed using the Optum electronic health records database. Incidence was assessed from PsO diagnosis and 1 year after PsO diagnosis overall and stratified by mutually exclusive treatment classes as a severity surrogate. RESULTS: The overall incidence of PsA was 2.9 (95% CI, 2.9-3.0) events per 100 PY. The incidence (95% CI) by severity surrogate was 2.1 (2.1-2.1), 9.9 (9.5-10.4), and 17.6 (16.9-18.3) events per 100 PY for patients with mild, moderate, and severe PsO as determined by receiving nonsystemics, nonbiologic systemic therapy, and biologics, respectively. When excluding patients diagnosed with PsA 1 year after PsO diagnosis, overall incidence was lower (1.7 [95% CI, 1.6-1.7] events per 100 PY), with similar trends for treatment-severity surrogates. LIMITATIONS: Results may not be generalizable to a wider population. CONCLUSION: The risk of developing PsA increased with disease severity and was highest in patients with the most severe PsO.

A systematic literature review of efficacy, effectiveness and safety of biologic therapies for treatment of familial Mediterranean fever.

OBJECTIVES: To identify and summarize the existing evidence on the efficacy, effectiveness and safety of biologic therapies used, either as indicated or off-label, in the treatment of FMF. METHODS: A systematic literature review was conducted using Embase®, MEDLINE®, MEDLINE®-In Process, and Cochrane databases to identify randomized/non-randomized controlled trials (RCTs/non-RCTs) and real-world observational studies of FMF published as full-text articles (2000-September 2017) or conference abstracts (2014-September 2017). Studies with data for ≥1 biologic were included. Studies with <5 patients were excluded. RESULTS: Of the 3342 retrieved records, 67 publications, yielding 38 unique studies, were included. All studies were published after the year 2010, and the majority (21) were full-text articles. Most studies (33/38) were prospective/retrospective observational; three were double-blind, placebo-controlled RCTs (one each of anakinra, canakinumab and rilonacept); and two were non-RCTs (both canakinumab). Anakinra (26), canakinumab (21) and etanercept (6) were the most frequently used biologics across studies, whereas use of adalimumab, tocilizumab, rilonacept and infliximab was limited (1-2 studies). The available evidence suggested benefits of anakinra and canakinumab in FMF. CONCLUSION: Anti-IL-1 therapies (i.e. anakinra and canakinumab) appear to be effective and safe options in the treatment of overall FMF, including patients with colchicine resistance and FMF-related amyloidosis. There is a need for properly designed prospective or controlled studies to conclude the superiority of one anti-IL-1 therapy over another. Evidence on the use of TNF-α and IL-6 inhibitors is limited, and further research is suggested.

Burden of illness in hereditary periodic fevers: a multinational observational patient diary study.

OBJECTIVES: This study aimed to characterise the burden of illness of patients with inadequately controlled hereditary periodic fevers (HPFs), during and outside of flares. It was focused on the burden to the patients and also considered the wider impact on their caregivers and families. METHODS: The target population was patients or caregivers of patients with clinically/genetically confirmed colchicine resistant FMF (crFMF), mevalonate kinase deficiency/hyperimmunoglobinaemia D with periodic fever syndrome (MKD/HIDS) or TRAPS, who were expected to flare at least once in a 6-month period based on patient history. Disease burden was captured during and between flares using an electronic diary (e-diary) with questions on patient functioning, emotional/social well-being and pain, using validated instruments. RESULTS: HPF-related symptoms such as fever, joint, muscle or bone pain and tiredness and fatigue were reported by patients both during and outside of a flare. The SF-10 Health Survey (SF-10v2) (paediatric patients) and SF-12 Health Survey (SF-12v2) (adult patients) showed that flares negatively impacted patients' psychosocial and physical health. Negative effect of on-flare status on health utility index score assessed by the Short-Form Six-Dimension (SF-6D) was significant only for crFMF patients. Furthermore, the Sheehan Disability Score (SDSv3) showing the on-flare status resulted in significant functional impairment in all 3 disease cohorts through assessment of impact on work/school, social and family life. CONCLUSIONS: crFMF, MKD/HIDS and TRAPS negatively affected the quality of life (QoL) of adult and paediatric patients, including their physical, mental, psychosocial health, and social functioning. There remains, however, a high number of unmet needs for these patients to reduce their disease burden.

Incidence rates of comorbidities among patients with psoriasis in the United States.

Psoriasis is associated with a substantial burden of comorbidities; however, incidence rates (IRs) of these comorbidities following psoriasis diagnosis are not well characterized. Using administrative claims data from the Truven Health Analytics MarketScan Commercial and Medicare Supplemental Databases between January 1, 2002 and September 30, 2015, we compared the incidence of newly diagnosed comorbidities among patients with psoriasis versus demographically matched (birth year, gender, and geographic region) control patients without psoriasis in the United States. Comorbidities of interest were identified using ICD-9-CM codes. A total of 114,824 matched pairs of patients with psoriasis and control patients were included. IRs of all selected comorbidities were significantly higher among patients with psoriasis compared with controls (P<0.05). The most common newly diagnosed comorbidities in both groups were hyperlipidemia (psoriasis versus control, IR per 1,000 patient-years, 127.5 versus 102.8) and hypertension (94.3 versus 80.6). The greatest differences in IRs between patients with psoriasis and controls were observed for rheumatoid arthritis (9.7 versus 3.1; IR ratio [IRR], 3.15) and psoriatic arthritis (24.0 versus 0.2; IRR, 151.57). In this real-world study, patients with psoriasis were more likely to develop new selected comorbidities after diagnosis compared with demographically matched patients without psoriasis.

Real-world effectiveness and safety of advanced therapies for the treatment of moderate-to-severe ulcerative colitis: Evidence from a systematic literature review.

BACKGROUND: Effectiveness and safety of advanced therapies for ulcerative colitis (UC) warrant assessment in the real world. OBJECTIVE: To perform a systematic review and summarize real-world evidence of advanced therapies approved for moderate-to-severe UC. METHODS: A systematic literature review was conducted using real-world studies of biologics or small molecules in UC using Embase, MEDLINE, and MEDLINE-In Process databases. Only products approved in any jurisdiction during the search were included. English-language full-papers (January 2005 to February 2022) and congress abstracts (January 2019 to February 2022) were included. Studies with less than 30 patients or only biologic-naive patients were excluded. RESULTS: A total of 139 studies were included out of 3,930 identified articles (75%, published between 2019 and 2022; 64%, retrospective observational; 53%, from 5 countries [Italy, United States, Spain, United Kingdom, and Belgium]). Most studies were single agent (highest: vedolizumab = 50, tofacitinib = 24, and adalimumab = 18), and rates of clinical remission (CR) and adverse events varied widely. From the published comparative effectiveness studies (16), the rates of CR were numerically higher with vedolizumab vs anti-tumor necrosis factor (TNF)-α agents. Compared with vedolizumab, the effectiveness of tofacitinib was numerically greater in CR (occasionally significant). Rates of steroid-free CR were comparable between ustekinumab and tofacitinib. Infliximab was the most effective anti-TNFα agent, as reported by 2 studies. Remarkably, adverse events were similar across therapies in comparative studies. CONCLUSIONS: Vedolizumab and tofacitinib were the most assessed therapies. In comparative studies, remission rates were numerically higher with tofacitinib vs vedolizumab and for vedolizumab vs anti-TNFα. Tofacitinib was comparable with ustekinumab for steroid-free CR. Safety was comparable across therapies. Future studies should explore the literature gaps identified, including limited comparative studies with small sample sizes, variations in study designs and patient characteristics, varied definitions of CR, and limited use of patient-reported outcome measures in real-world settings.

Characteristics and 6-Month Outcomes in Patients with Rheumatoid Arthritis Initiating Infliximab Biosimilar IFX-dyyb in a Real-World Setting.

INTRODUCTION: Real-world studies describing biosimilar initiation or switching in patients with rheumatoid arthritis (RA) are limited. The aim of this study was to assess treatment patterns and effectiveness of real-world patients with RA initiating infliximab biosimilar IFX-dyyb (CT-P13; Inflectra®) in the USA. METHODS: This observational study evaluated patients with RA from the CorEvitas RA Registry who initiated IFX-dyyb and had Clinical Disease Activity Index (CDAI) recorded at baseline and 6 months. The primary outcome was reaching low disease activity (LDA; CDAI ≤ 10) at 6 months in patients with moderate or high disease activity (CDAI > 10) at baseline. Secondary outcomes were change at 6 months in CDAI and certain patient-reported outcomes (PROs). Patient data were stratified by prior treatment: biologic/targeted synthetic disease-modifying antirheumatic drug (tsDMARD)-naïve, reference infliximab (IFX-REF) or IFX biosimilar, or a non-IFX biologic or tsDMARD. RESULTS: Of 318 patients initiating IFX-dyyb, 176 had baseline and 6-month CDAI scores; 73 (41%) switched from IFX, 61 (35%) switched from another non-IFX/biologic/tsDMARD, 32 (18%) were naïve to biologics/tsDMARDs, and 10 (6%) switched from an IFX biosimilar. Among patients with moderate or high disease activity at baseline, 32.9% (95% CI 22.9, 42.9) achieved LDA at 6 months. Mean 6-month change from baseline in CDAI was - 1.8 (95% CI - 3.3, - 0.3) overall; - 4.7 (- 7.6, - 1.7) in patients who switched from a non-IFX biologic/tsDMARD, - 4.1 (- 7.8, - 0.3) in biologic/tsDMARD-naïve patients, and 1.1 (- 0.4, 2.6) in patients who switched from IFX-REF/IFX biosimilar. Other clinical outcomes/PROs improved at 6 months. Of the IFX-dyyb initiators, 68% remained on IFX-dyyb at 6 months. CONCLUSION: In this real-world population of patients with RA initiating IFX-dyyb, the majority switched from IFX-REF or a non-IFX biologic/tsDMARD. CDAI remained stable in patients switching from IFX-REF/IFX biosimilar and improved in patients switching from a non-IFX biologic/tsDMARD and in biologic/tsDMARD-naïve patients.

Infliximab is an effective treatment for rheumatoid arthritis (RA). Biosimilars­biologic drugs designed to be very similar to the originator products­are now available that may be more affordable with matching efficacy and safety. IFX-dyyb is a US Food and Drug Administration-approved infliximab biosimilar but little is known about its use in real-world clinical practice in patients with RA in the USA. This study used data from a large observational registry to look at treatment patterns and effectiveness of IFX-dyyb in adults with RA. One hundred and seventy-six patients were included who had data available at both baseline and at 6 months. Most patients (47%) switched to IFX-dyyb from the originator infliximab or another infliximab biosimilar; 35% switched from another RA treatment, and 18% were new to treatment. Six months after starting IFX-dyyb, 68% of patients were still receiving treatment. A measure of clinical disease activity remained stable in patients who switched from originator infliximab or another biosimilar, while this measure improved in patients switching to IFX-dyyb from other treatments or starting treatment for the first time. Other clinical measures and patient-reported outcomes such as pain and fatigue also improved over 6 months with IFX-dyyb. This real-world study of patients with RA initiating IFX-dyyb in the USA adds to our knowledge of the use of biosimilars in this patient population.

Health-Related Quality of Life Outcomes With Tofacitinib Treatment in Patients With Ulcerative Colitis in the Open-Label Extension Study, OCTAVE Open.

BACKGROUND: Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis. We report health-related quality of life (HRQoL) outcomes in patients with ulcerative colitis in the phase 3 open-label, long-term extension study, OCTAVE Open. METHODS: The Inflammatory Bowel Disease Questionnaire (IBDQ), EuroQoL-5 Dimensions Health Questionnaire, and 36-Item Short Form Survey scores were analyzed up to month (M) 72 in 4 subpopulations: patients in remission at baseline (maintenance remitters) assigned tofacitinib 5 mg twice daily and patients not in remission at baseline (maintenance nonremitters, maintenance treatment failures, and induction nonresponders [IndNRs]) assigned tofacitinib 10 mg twice daily in OCTAVE Open. Data were analyzed overall and stratified by corticosteroid use at baseline, prior tumor necrosis factor inhibitor failure, and prior immunosuppressant failure. RESULTS: Among maintenance remitters and nonremitters, HRQoL outcomes were maintained up to M72: 80.0% and 100.0% of patients had an IBDQ total score ≥170, respectively. At baseline, 7.4% of maintenance treatment failures had an IBDQ total score ≥170, and this increased to 54.3% and 75.0% at M2 and M72, respectively. Corresponding values for IndNRs were 22.6%, 51.0%, and 86.0%. HRQoL outcomes were independent of treatment history. Among patients not in remission at baseline, improvement in EuroQoL-5 Dimensions Health Questionnaire and 36-Item Short Form Survey scores was maintained or achieved by M2, and steady to M72 or M33, with maintenance treatment failures and IndNR subpopulations undergoing the biggest improvements from baseline. CONCLUSIONS: A continued favorable impact on HRQoL was revealed with long-term tofacitinib treatment in OCTAVE Open, regardless of baseline remission status or treatment history. (ClinicalTrials.gov; number: NCT01470612).

Health-related quality of life was assessed in patients with ulcerative colitis in an open-label, long-term extension study, OCTAVE Open. Patients had sustained beneficial effects on health-related quality of life with long-term tofacitinib treatment, regardless of treatment history/remission status at OCTAVE Open baseline.

Disease Activity and Health-related Quality of Life Relationships with Work Productivity in Patients with Ulcerative Colitis in OCTAVE Induction 1 and 2 and OCTAVE Sustain.

BACKGROUND: Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis [UC]. We evaluated the relationship between Mayo/Inflammatory Bowel Disease Questionnaire [IBDQ] scores and Work Productivity and Activity Impairment-UC [WPAI-UC] components in patients with UC. METHODS: All available pooled data from three Phase 3 tofacitinib studies [OCTAVE Induction 1 and 2 and OCTAVE Sustain] were included. Relationships were estimated using repeated measures regression models with Mayo score/subscores or IBDQ total/domain scores as a separate anchor predictor and WPAI-UC components as the outcome. RESULTS: Evidence for linear relationships was confirmed between Mayo/IBDQ scores and WPAI-UC components. Robust relationships between total Mayo score/IBDQ total score and WPAI-UC presenteeism, work productivity loss, and activity impairment were observed; relationships with absenteeism were weak. Total Mayo scores of 0 and 12 corresponded, on average, to WPAI-UC component scores of < 15% and ≥ 60%, respectively, and IBDQ total scores of 224 and 32 corresponded, on average, to WPAI-UC component scores of < 6% and ≥ 90%, respectively. Presenteeism, work productivity loss, and activity impairment [all 0-100%], respectively, improved on average by 14.7, 13.6, and 16.4 percentage points for every 3-point improvement in total Mayo score, and by 8.1, 7.9, and 8.8 percentage points for every 16-point improvement in IBDQ total score. CONCLUSION: Robust relationships between Mayo/IBDQ scores with WPAI-UC presenteeism, work productivity loss, and activity impairment suggest that patient productivity and non-work activities are strongly associated with disease activity and HRQoL. The weak relationships with absenteeism suggest that patients attend work regardless of their disease activity/poor HRQoL. ClinicalTrials.gov: NCT01465763;NCT01458951;NCT01458574.

Systematic Literature Review: Ability of the IBDQ-32 to Detect Meaningful Change in Ulcerative Colitis Health Indicators.

PURPOSE: Previous reviews produced weak evidence regarding the responsiveness of the Inflammatory Bowel Disease Questionnaire (IBDQ-32) to changes in ulcerative colitis (UC) health indicators. This systematic review and meta-analysis provide an updated synthesis on IBDQ-32 responsiveness. METHODS: A systematic literature review identified 11 articles reporting IBDQ-32 responder analyses in randomized control trials, which were included in a random effects meta-analysis, and 15 articles linking IBDQ-32 change to change in UC health indicators, which were summarized narratively. Meta-analysis compared differences between IBDQ-32 responder proportions in efficacious and nonefficacious treatment arms relative to placebo. Linear meta-regression examined the association of treatment efficacy and proportions of IBDQ-32 responders in active treatment compared with placebo. RESULTS: Meta-analysis showed larger differences in IBDQ-32 response proportions between active treatment and placebo for efficacious treatments (pooled OR, 2.19; 95% CI, 1.83-2.63) than nonefficacious treatments (pooled OR, 1.21; 95% CI, 0.84-1.74; Cochran's Q[df = 1] = 8.26, P = .004). Meta-regression showed that the magnitude of treatment efficacy positively predicted IBDQ-32 response in active treatments relative to placebo (ß = 0.21, P < .001). Moderate to strong correlations were found between change in IBDQ-32 and change in health indicators (eg, patient-reported measures, disease activity, endoscopic indices; correlations, 0.37-0.64 in absolute values). Patients achieving clinical response or remission showed greater change in IBDQ-32 total scores (range, 22.3-50.1 points) and more frequently met clinically meaningful thresholds on the IBDQ-32 than those not achieving clinical response or remission (all P < .05). CONCLUSIONS: The IBDQ-32 is responsive to changes in UC health indicators and disease activity, including in response to efficacious treatment (relative to placebo).

This article presents a review of evidence on the responsiveness of the 32-item Inflammatory Bowel Disease Questionnaire, a widely used patient-report measure of health-related quality of life. W found a generally good ability of the instrument to detect changes in ulcerative colitis health that are meaningful to patients and clinicians.

Comparison of Clinical Manifestations in Rheumatoid Arthritis vs. Spondyloarthritis: A Systematic Literature Review.

INTRODUCTION: Misclassification of spondyloarthritis (SpA) as rheumatoid arthritis (RA) may lead to delayed SpA diagnosis and suboptimal therapeutic outcomes. Here, we evaluate the literature on clinical manifestations in patients with SpA and RA, particularly seronegative RA, to understand the potential overlap, distinctions, and most reliable approaches to accurate diagnosis. METHODS: In this systematic literature review, conducted according to PRISMA guidelines, we searched key biomedical databases for English-language publications of original research articles (up to July 23, 2020) and rheumatology conference abstracts (January 1, 2018-July 31, 2020) reporting key SpA clinical presentations in patients with SpA or RA. Publications were assessed for eligibility by two independent reviewers; discrepancies were resolved by a third. Studies were evaluated for publication quality using the Downs and Black checklist. RESULTS: Of 4712 records retrieved, 79 met the inclusion criteria and were included in the analysis. Of these, 54 included study populations with SpA and RA, and 25 with seropositive and/or seronegative RA. Entheseal abnormalities were more frequently reported among patients with SpA than RA and with seronegative vs. seropositive RA. Psoriasis, nail psoriasis, and dactylitis were exclusively seen in SpA vs. RA. In most publications (70 of 79), advanced imaging techniques allowed for more accurate distinction between SpA and RA. Overlapping clinical characteristics occur in SpA and RA, including inflammation and destruction of joints, pain, diminished functional ability, and increased risk for comorbidities. However, of 54 studies comparing SpA and RA populations, only seven concluded that no distinction can be made based on the SpA manifestations and outcomes examined. CONCLUSIONS: Typical SpA-related clinical symptoms and signs were observed in patients with RA, suggesting that misclassification could occur. Availability of advanced imaging modalities may allow for more prompt and comprehensive evaluation of peripheral manifestations in SpA and RA, reducing misclassification and delayed diagnosis.

Spondyloarthritis (SpA) is a group of chronic, inflammatory diseases that includes axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA), in addition to other peripheral forms of SpA. AxSpA primarily affects the spine and can cause chronic back pain. PsA occurs in patients with the skin condition psoriasis and patients often experience symptoms including joint pain, stiffness, and swelling. Quick and accurate diagnosis of SpA is necessary to prevent joint damage and physical limitations. Rheumatoid arthritis (RA) is characterized by pain, swelling, and stiffness in multiple joints, and delayed diagnosis and treatment can have lasting effects. However, many patients with SpA and RA who initially seek medical care often experience delayed diagnoses. This study evaluated the literature on symptoms in patients with SpA and RA, particularly patients with RA without antibodies typically associated with the disease, to understand the potential overlap, differences, and most reliable ways to accurately diagnose patients. Data from 79 records were included in the analysis, 54 of which included study populations with SpA and RA. Skin and nail psoriasis, as well as swelling of the fingers and toes, was only seen in patients with SpA. Most studies showed that enhanced imaging allowed for distinguishing between SpA and RA. This study showed that typical signs and symptoms of SpA, including inflammation and joint pain, could also be seen in patients with RA, which suggests that challenges exist for accurately identifying SpA. This highlights the importance of advanced imaging to diagnose and treat patients with SpA in a timely manner.

Effectiveness of 6-month Use of Secukinumab in Patients With Psoriatic Arthritis in the CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry.

OBJECTIVE: To evaluate clinical and patient-reported outcomes (PROs) at 6 months after secukinumab initiation in US patients with psoriatic arthritis (PsA). METHODS: Patients with PsA in the CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry who initiated secukinumab between April 1, 2017, and December 2, 2019, and maintained secukinumab at their 6-month follow-up visit were included. Achievement of minimal disease activity (MDA) among patients not in MDA at initiation; resolution (ie, no evidence) of tender and swollen joint counts, enthesitis, and dactylitis among patients with ≥ 1 of these at initiation; and change in disease activity and PROs were evaluated at 6 months in all patients and in patients who received secukinumab as a first-line biologic. RESULTS: Of the 100 eligible patients included, most (83.0%) were biologic experienced and 17.0% initiated secukinumab as a first-line biologic. At initiation, 75/90 patients (83.3%) with available data were not in MDA; 26/71 (36.6%) with follow-up data achieved MDA at 6 months. Further, 28/68 patients (41.2%) with ≥ 1 tender joint, 24/54 (44.4%) with ≥ 1 swollen joint, 17/28 (60.7%) with enthesitis, and 9/12 (75.0%) with dactylitis at initiation achieved resolution at 6 months. Improvements in clinical manifestations, PRO measures, and work productivity and activity were observed after 6 months among patients with PsA who initiated and maintained secukinumab. CONCLUSION: In this real-world population, patients with PsA who received and maintained secukinumab for 6 months achieved MDA in proportions consistent with clinical trials and demonstrated improvements in clinical manifestations and PROs.

Evaluation of Clinical Diagnosis of Axial Psoriatic Arthritis (PsA) or Elevated Patient-reported Spine Pain in CorEvitas' PsA/Spondyloarthritis Registry.

OBJECTIVE: To determine the presence of axial symptoms in patients with psoriatic arthritis (PsA) and examine differences between those with or without a diagnosis of axial PsA (axPsA). METHODS: Patients with PsA at their Corevitas' (formerly Corrona) Psoriatic Arthritis/Spondyloarthritis Registry enrollment visit were stratified into 4 mutually exclusive groups based on axial manifestations: physician-diagnosed axPsA only (Dx+Sx-), patient-reported elevated spine symptoms only (Dx-Sx+; defined as Bath Ankylosing Spondylitis Disease Activity Index ≥ 4 and spine pain visual analog scale ≥ 40), physician-diagnosed and patient-reported manifestations (Dx+Sx+), and no axial manifestations (Dx-Sx-). Patient characteristics, disease activity, and patient-reported outcomes (PROs) at enrollment in each axial manifestation group were compared with the Dx-Sx- group. Associations of patient characteristics with the odds of having axial manifestations were estimated using multinomial logistic regression (reference: Dx-Sx-). RESULTS: Of 3393 patients included, 226 (6.7%) had Dx+Sx-, 698 (20.6%) had Dx-Sx+, 165 (4.9%) had Dx+Sx+, and 2304 (67.9%) had Dx-Sx-. Patients with Dx-Sx+ or Dx+Sx+ were more frequently women and had a history of depression and fibromyalgia (FM) vs patients who had Dx-Sx-. Patients with Dx+Sx- or Dx+Sx+ were more frequently HLA-B27 positive than those with Dx-Sx-. FM was significantly associated with increased odds of Dx+Sx- or Dx+Sx+. Disease activity and PROs were worse in patients with Dx-Sx+ or Dx+Sx+ than in those with Dx-Sx-. CONCLUSION: Patients who had self-reported elevated spine symptoms, with or without physician-diagnosed axPsA, had worse quality of life and higher disease activity overall than patients without axial manifestations, suggesting an unmet need in this patient population.

Reasons for Initiating Canakinumab among Patients with Systemic Juvenile Idiopathic Arthritis and Adult-Onset Still's Disease in the U.S. Real-World Settings.

INTRODUCTION: The aim of this study was to understand the reasons for canakinumab initiation among patients with Still's disease, including systemic juvenile idiopathic arthritis (SJIA) and adult-onset Still's disease (AOSD), in US clinical practice. METHODS: Physicians retrospectively reviewed the medical charts of patients with Still's disease (regardless of age at symptom onset) who were prescribed canakinumab from 2016 to 2018. Patients aged < 16 years at symptom onset were classified as having SJIA and those aged ≥ 16 years at symptom onset (calculated from case-record forms) were classified as having AOSD. Patient treatment history and physician reasons for canakinumab initiation were analyzed. Overall results were presented as SJIA/AOSD. Sensitivity analyses were performed for the robustness of the results. RESULTS: Forty-three physicians in the USA (rheumatologists/dermatologists/immunologists/allergists: 51.2/27.9/11.6/9.3%; subspecialty in adults/pediatrics: 67.4/32.6%) abstracted information for 72 patients with SJIA/AOSD (SJIA/AOSD/age unknown at symptom onset: 75.0/18.1/6.9%; mean age 19.4 years; children 61.1%; females 56.9%). Most patients (90.3%) received treatment directly preceding canakinumab initiation (etanercept 27.7%; anakinra 18.5%; adalimumab 16.9%); the respective treatment was discontinued due to lack of efficacy/effectiveness (43.1%) and availability of a new treatment (27.8%). Most common reasons for canakinumab initiation were physician perceived/experienced efficacy/effectiveness of canakinumab (77.8%; children/adults: 81.8/71.4%), lack-of-response to previous treatment (45.8%; children/adults: 36.4/60.7%), convenient administration/dosing (26.4%; children/adults: 29.5/21.4%) and ability to discontinue/spare steroids (25.0%; children/adults: 20.5/32.1%). The sensitivity analysis provided similar results. CONCLUSIONS: In US clinical practice, physician perceived/experienced efficacy/effectiveness of canakinumab and lack-of-response to previous treatment were the primary reasons for canakinumab initiation among patients with SJIA/AOSD. Physician perceived/experienced efficacy/effectiveness and convenient administration/dosing of canakinumab were the most common reasons for canakinumab initiation among children, whereas lack-of-response to previous treatment and ability to discontinue/spare steroids being the most frequent reasons among adults.

Health care utilization and costs associated with functional status in patients with psoriatic arthritis.

BACKGROUND: The Health Assessment Questionnaire Disability Index (HAQ-DI) has been validated and widely used in psoriatic arthritis (PsA) clinical trials for the assessment of patient functional status. Significant improvements in the HAQ-DI have been reported in response to therapeutic interventions; however, few US studies have evaluated the economic impact of functional disability in patients with PsA. OBJECTIVE: To evaluate the association of functional status with health care resource utilization (HCRU) and total health care costs in US patients diagnosed with PsA. METHODS: This retrospective study included adult patients with PsA enrolled in FORWARD between July 2009 and June 2019 who completed 1 or more HAQ-DI questionnaires between January 2010 and December 2019. Patient demographics, clinical characteristics, and patient-reported outcomes were collected from the most recent questionnaire. HCRU and total health care costs (2019 US dollars) for all hospitalizations, emergency department (ED) visits, outpatient visits, diagnostic tests, and procedures were assessed for the 6 months prior to survey completion. Negative binomial regression models (HCRU outcomes) and generalized linear models with γ distribution and log-link function (cost outcomes) were used to assess the relationship between HAQ-DI and HCRU and cost outcomes, respectively. RESULTS: A total of 828 patients with PsA who completed HAQ-DI questionnaires were included. The mean (SD) age was 58.5 (13.5) years, 72.3% were female, and 92.3% were White. The mean (SD) disease duration was 17.5 (12.4) years, and the mean (SD) HAQ-DI score at the time of the patients' most recent questionnaire was 0.9 (0.7). More severe functional disability, measured by higher HAQ-DI score, was significantly associated with increased risk (incident rate ratio [95% CI]) of hospitalizations (1.68 [1.11-2.55]), ED visits (2.09 [1.47-2.96]), outpatient visits (1.14 [1.05-1.24]), and diagnostic tests (1.42 [1.16-1.74]). There was also a significant positive association between greater HAQ-DI score and increased total annualized health care costs (incremental amount [95% CI], 1.13 [1.03-1.23]) and medical costs (1.38 [1.13-1.69]), but there was no significant association found with pharmacy costs. Total adjusted average patient medical costs increased with increasing HAQ-DI score. CONCLUSIONS: Among patients with PsA enrolled in FORWARD, more functional disability-as measured by higher HAQ-DI scores-was associated with greater HCRU and increased total health care costs. These results suggest that improving functional status in patients with PsA may reduce economic burden for health care payers and systems.

The effect of secukinumab on patient-reported outcomes in patients with active psoriatic arthritis in a randomised phase 3 trial.

BACKGROUND: The phase 3 FUTURE 5 trial (NCT02404350) showed the clinical and radiographical efficacy of secukinumab in patients with psoriatic arthritis. This analysis aimed to assess the effect of secukinumab on patient-reported outcomes (PROs). METHODS: FUTURE 5 was a phase 3, multicentre, parallel-group randomised trial in which patients who were 18 years old or older, met the classification criteria for psoriatic arthritis at screening, and had symptoms of moderate-to-severe psoriatic arthritis for at least 6 months were randomly assigned to receive secukinumab 300 mg, 150 mg, 150 mg no loading dose (NL), or placebo weekly from baseline to week 4 and every 4 weeks thereafter. The prespecified PROs of the FUTURE 5 trial were assessed first in the overall population. We report mean changes from baseline and the proportion of patients reporting improvements equal to or more than the minimum clinically important differences (MCIDs) and scores equal to or more than the normative values for patient global assessments (PtGA) of disease activity; psoriasis and arthritis visual analogue scale (VAS) scores; pain VAS; Health Assessment Questionnaire Disability Index (HAQ-DI); 36-item Short Form Health Survey (SF-36); Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F); and quality of life questionnaires. Patients were then stratified and assessed according to their tumour necrosis factor (TNF) inhibitor status (TNF-naive and TNF-inadequate responder [TNF-IR] populations) as a post-hoc analysis. FINDINGS: Patients in all secukinumab groups reported significant least-squares mean changes from placebo at week 16 in all PROs except SF-36 mental component summary (MCS), irrespective of TNF inhibitor use. These included PtGA (300 mg difference vs placebo -12·2 [95% CI -16·3 to -8·1], 150 mg -8·22 [-12·4 to -4·1], 150 mg NL -8·3 [-12·5 to -4·2]; all p<0·0001), pain VAS (300 mg -14·3 [-18·3 to -10·2], 150 mg -11·5 [-15·6 to -7·5], 150 mg NL -11·3 [-15·3 to -7·2]; all p<0·0001), HAQ-DI (300 mg -0·33 [-0·42 to -0·24], 150 mg -0·23 [-0·32 to -0·14], 150 mg NL -0·24 [-0·33 to -0·15]; all p<0·0001), and FACIT-F (300 mg 4·8 [3·2 to 6·4], 150 mg 4·2 [2·6 to 5·8], 150 mg NL 3·5 [1·9 to 5·1]; all p<0·0001). Similarly, the proportion of patients with improvements equal to or better than MCID at week 16 was higher in the secukinumab group compared with the placebo group for most PROs except SF-36 (MCS), regardless of TNF inhibitor use. INTERPRETATION: Secukinumab resulted in early, statistically significant, clinically meaningful, sustained improvements in PROs across all doses compared with placebo in patients with active psoriatic arthritis. These improvements were seen irrespective of previous TNF inhibitor use, in a post-hoc analysis. These results indicate that secukinumab provides comprehensive improvement for patients with psoriatic arthritis, regardless of previous therapy. FUNDING: Novartis.

Adult-onset Still's disease in focus: Clinical manifestations, diagnosis, treatment, and unmet needs in the era of targeted therapies.

BACKGROUND: Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disorder of unknown etiology, characterized by a clinical triad of high spiking fever, arthralgia (± arthritis), and evanescent skin rash. Management of AOSD poses several challenges, including difficulty in diagnosis and limited therapeutic options. In this review, we examined whether AOSD and systemic juvenile idiopathic arthritis (SJIA) represent a continuum of the same disease. We also explored the latest available evidence related to prevalence, clinical and laboratory manifestations, complications, diagnostic challenges, novel biomarkers, and treatment options in the era of biologics and identified the unmet needs of patients with AOSD. METHODS: A comprehensive systematic literature search was performed in the Embase and MEDLINE (via PubMed) literature databases. The search was limited to human studies published in English from inception up to March 2020. Additionally, abstracts presented at various conferences were screened and hand searches were performed. Publications were processed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: A total of 123 publications were identified through the literature search, majority of which were case series and retrospective observational studies. AOSD and SJIA are widely considered part of the same disease spectrum owing to similarities in their clinical and biological features. The clinical presentation of AOSD is highly variable, accompanied by a broad spectrum of disease manifestations. Recent evidence suggests that the AOSD disease course can be classified into two distinct categories: "systemic" and "articular." Furthermore, AOSD patients may experience various life-threatening complications, such as macrophage activation syndrome - reported in as high as 23% of AOSD patients and considered to be the most severe complication characterized by a high mortality rate. The ambiguity in presentation and lack of serologic markers make the diagnosis of AOSD difficult, often leading to a delay in diagnosis. Given these limitations, the Yamaguchi and Fautrel criteria are the most widely used diagnostic tools in clinical practice. It has been observed that a clinical diagnosis of AOSD is generally reached by exclusion while investigating a patient with fever of unknown origin. Recent advances have demonstrated a major role of proinflammatory cytokines, such as interleukin (IL)-1, IL-6, IL-18, and IL-37, and other biomarkers in the pathogenesis and management of AOSD. Owing to the rarity of the disease, there are very limited clinical trials evaluating management strategies for AOSD. The current AOSD treatment paradigm includes non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids initially, conventional synthetic disease-modifying anti-rheumatic drugs in steroid-refractory patients, and biologics in those resistant to conventional treatment. Only a few country-specific guidelines for the management of AOSD have been published, and a treat-to-target approach, as previously recommended for SJIA, is still lacking. Canakinumab is the only FDA-approved biologic for the treatment of AOSD. CONCLUSION: Emerging evidence supports that AOSD and SJIA represent a continuum of the same disease entity. Despite advancements in the understanding of AOSD, it continues to pose a substantial burden on patients and the healthcare systems, and substantial unmet needs exist across key domains such as the pathway to diagnosis, use of biomarkers in clinical practice, and standardized treatment strategies. Further research and collaboration is crucial for optimizing the diagnosis and management of AOSD patients.

Longitudinal analysis of the patient pathways to diagnosis of psoriatic arthritis.

BACKGROUND: The occurrence of health events preceding a psoriatic arthritis (PsA) diagnosis may serve as predictors of diagnosis. We sought to assess patients' real-world experiences in obtaining a PsA diagnosis. METHODS: This retrospective cohort study analyzed MarketScan claims data from January 2006 to April 2019. Included were adult patients with ≥ 2 PsA diagnoses (ICD-9-CM/ICD-10-CM) ≥ 30 days apart with ≥ 6 years of continuous enrolment before PsA diagnosis. Controls were matched 2:1 to patients with PsA. Health events (diagnoses and provider types) were analyzed before PsA diagnosis and additionally stratified by presence of psoriasis. RESULTS: Of 13,661 patients, those with PsA had an increased history of coding for arthritis and dermatologic issues (osteoarthritis [48% vs 22%], rheumatoid arthritis [18% vs 2%], and psoriasis [61% vs 2%]) vs those without PsA. Diagnoses of arthritis, axial symptoms, and tendonitis/enthesitis increased over time preceding PsA diagnosis; notably, a sharp rise in psoriasis diagnoses was observed 6 months before PsA diagnosis. Rheumatology consults were more common immediately preceding a PsA diagnosis. Dermatologists were unlikely to code for arthritis and musculoskeletal issues, while rheumatologists were unlikely to code for psoriasis; general practitioners focused on axial and musculoskeletal symptoms. PsA was most commonly diagnosed by rheumatologists (40%), general practitioners (22%), and dermatologists (7%). CONCLUSIONS: Rheumatologists, general practitioners, and dermatologists diagnosed two thirds of patients with PsA. Musculoskeletal symptoms were common preceding a PsA diagnosis. Greater awareness of patterns of health events may alert healthcare providers to suspect a diagnosis of PsA.

Healthcare Cost and Utilization Associated with Biologic Treatment Patterns Among Patients with Psoriatic Arthritis: Analyses from a Large US Claims Database.

BACKGROUND: Costs associated with biologic switching and discontinuation can be high in psoriatic arthritis (PsA), and their inappropriate use may have cost implications for patients, healthcare professionals, and payers. OBJECTIVE: To compare direct costs of treatment switchers, non-switchers, and discontinuers among patients with PsA who newly initiated a biologic. METHODS: Patients with PsA aged ≥ 18 years with ≥ 1 pharmacy claim for an FDA-approved subcutaneous biologic from 1 January 2016 to 31 December 2016 were identified from the Truven Health MarketScan Databases. Patients were categorized into three mutually exclusive groups of non-switchers, switchers, and discontinuers, and healthcare costs and utilization during 1-year follow-up were described across the three groups separately. RESULTS: A total of 2560 patients with PsA newly initiating a biologic were categorized as non-switchers (54.8%), switchers (18.5%), and discontinuers (26.7%). During 1-year follow-up, after adjusting for age, sex, full-time work status, and co-morbidities, switchers had higher mean total all-cause healthcare costs than non-switchers (US$80,380 vs. US$69,031), driven by increased pharmacy (US$66,531 vs. US$56,674) and outpatient (US$10,881 vs. US$8,235) costs (all P < 0.0001). Discontinuers had the lowest mean total all-cause healthcare costs (US$50,054) but the highest medical costs (US$20,323). Switchers and discontinuers had higher all-cause healthcare utilization than non-switchers during 1-year follow-up, except switchers had fewer hospitalizations. CONCLUSIONS: Patients with PsA who switch or discontinue biologics have higher medical costs and healthcare utilization than those continuing the same biologic. These findings highlight that  discontinuing or switching biologic therapies is associated with higher costs in patients with PsA, which may inform treatment and/or formulary decision-making.
