Real-World Postmarketing Study of the Impact of Adalimumab Treatment on Work Productivity and Activity Impairment in Patients with Psoriatic Arthritis.

ABSTRACT:

Introduction

This study investigated the effectiveness of adalimumab treatment in improving Work Productivity and Activity Impairment (WPAI) in patients with psoriatic arthritis (PsA) in real-world settings in Japan.

Methods

This 24-week, single-arm, postmarketing surveillance study (2014-2017), conducted at 75 centers in Japan, enrolled adalimumab-naïve patients (paid workers, including part-time) meeting ClASsification criteria for Psoriatic ARthritis (CASPAR). The primary endpoint was improvement in overall work impairment (OWI) scores from baseline to week 24. Secondary endpoints included changes in WPAI-PsA (OWI, absenteeism, presenteeism, and activity impairment), Psoriasis Area and Severity Index (PASI), psoriatic arthritis screening and evaluation (PASE) scores, Disease Activity Scores in 28 joints using C-reactive protein (DAS28[CRP]), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores, Health Assessment Questionnaire-Disability Index (HAQ-DI) scores, and PASI75/90 and American College of Rheumatology (ACR) 20/50/70 rates.

Results

In the effectiveness population (n = 106; 72.6% men; mean ± standard deviation [SD] age, 49.3 ± 10.7 years), OWI scores significantly improved (mean ± SD change, - 25.2 ± 35.3; p < 0.0001) from baseline to week 24. Other WPAI domain scores also improved significantly. Changes in OWI were significantly correlated (p < 0.0001) with PASE (r = 0.6284), DAS28(CRP) (r = 0.6059), BASDAI (r = 0.7281), and HAQ-DI (r = 0.6161) scores and were significantly influenced by previous nonsteroidal anti-inflammatory drug use (p = 0.0142), and baseline PASE (p = 0.0098), DAS28(CRP) (p = 0.0026), HAQ-DI (p = 0.0004), and BASDAI (p < 0.0001) scores. At the last evaluation, rate (95% confidence interval) of PASI 75 and 90 (n = 100) was 58.0% (47.7-67.8) and 39.0% (29.4-49.3), respectively, and that of ACR 20, 50, and 70 (n = 58) was 86.2% (74.6-93.9), 70.7% (57.3-81.9), and 53.4% (39.9-66.7), respectively. No new safety signals were observed in the safety population (n = 148).

Conclusion

Adalimumab treatment improved WPAI in patients with PsA. Improvements in OWI and joint symptoms were significantly associated.

Project description:IntroductionThe Work Productivity and Activity Impairment Specific Health Problem Questionnaire (WPAI:SHP) is used to assess the impact of an intervention on work productivity in patients with psoriatic arthritis (PsA). Unfortunately, studies reporting changes or improvements in domains of WPAI:SHP by patients with PsA have a limited threshold of meaning due to the absence of published minimal clinically important differences (MCIDs). Our objective was to determine the MCIDs for improvement in WPAI:SHP in patients with active PsA.MethodsMCIDs for WPAI:SHP domains (presenteeism, work productivity loss, and activity impairment) were derived for patients with active PsA who were biologic naïve or TNF inhibitor (TNFi) experienced using 24-week results from two phase 3 trials (SPIRIT-P1 and SPIRIT-P2). MCIDs were derived using the anchor-based method supplemented by the distribution-based method. Anchors included achievement of the American College of Rheumatology 20 responder index (ACR20), the minimal disease activity (MDA), and the Health Assessment Questionnaire and Disability Index (HAQ-DI) MCID (improvement ≥ 0.35). Anchor validity was assessed by biserial correlation and analysis of covariance modeling against the domains. MCIDs were triangulated using the receiver operating characteristic (ROC) method supplemented by the distribution-based method.ResultsThe analyses included 417 biologic-naïve and 363 TNFi-experienced patients. ACR20, MDA, and HAQ-DI were valid anchors. Significant differences in WPAI:SHP domain scores were observed between patients achieving ACR20, MDA, or HAQ-DI compared to patients not achieving these clinical thresholds (all P < 0.001). ROC analyses suggested that a ≥ 20% improvement in presenteeism, a 15% improvement in work productivity loss, and a 20% improvement in activity impairment represented clinically meaningful improvements in both populations. The distribution-based method supported the results.ConclusionMCIDs for the presenteeism, work productivity loss, and activity impairment domains were estimated to be 20%, 15%, and 20%, respectively, in biologic-naïve or TNFi-experienced PsA populations. These results will help improve the meaningfulness of WPAI:SHP improvements reported by PsA patients.Trial registrationSPIRIT-P1: NCT01695239, SPIRIT-P2: NCT02349295.FundingEli Lilly and Company.

Project description:The novel arthritis-specific Work Productivity Survey (WPS) was developed to estimate patient productivity limitations associated with arthritis within and outside the home, which is an unmet need in psoriatic arthritis (PsA). The WPS has been validated in rheumatoid arthritis. This report assesses the discriminant validity, responsiveness and reliability of the WPS in adult-onset PsA.Psychometric properties were assessed using data from the RAPID-PsA trial (NCT01087788) investigating certolizumab pegol (CZP) efficacy and safety in PsA. WPS was completed at baseline and every 4 weeks until Week 24. Validity was evaluated at baseline via known-groups defined using first and third quartiles of patients' Disease Activity Score 28 based on C-reactive protein (DAS28(CRP)), Health Assessment Questionnaire-Disability Index (HAQ-DI), Short Form-36 (SF-36) items and PsA Quality of Life (PsAQoL) scores. Responsiveness and reliability were assessed by comparing WPS mean changes at Week 12 in American College of Rheumatology 20% improvement criteria (ACR20) or HAQ-DI Minimal Clinically Important Difference (MCID) 0.3 responders versus non-responders, as well as using standardized response means (SRM). All comparisons were conducted on the observed cases in the Randomized Set, regardless of the randomization group, using a non-parametric bootstrap-t method.Compared with patients with a better health state, patients with a worse health state had on average 2 to 6 times more household work days lost, more days with reduced household productivity, more days missed of family/social/leisure activities, more days with outside help hired and a significantly higher interference of arthritis per month. Among employed patients, those with a worse health state had 2 to 4 times more workplace days lost, more days with patient workplace productivity reduced, and a significantly higher interference of arthritis on patient workplace productivity versus patients with a better health state. WPS was also responsive to clinical changes, with responders having significantly larger improvements at Week 12 in WPS scores versus non-responders. The effect sizes for changes in productivity in ACR20 or HAQ-DI MCID responders were moderate (0.5 < SRM < 0.8) or small.These analyses demonstrate the validity, responsiveness and reliability of the WPS, as an instrument for the measurement of patient productivity within and outside the home in an adult-onset PsA population.

Project description:BackgroundTo evaluate the real-world effect of the IL-12/23 inhibitor ustekinumab or of a tumour necrosis factor inhibitor (TNFi) on patient-reported outcomes (PRO) and their association with effectiveness endpoints in psoriatic arthritis (PsA) patients over 3 years.MethodsIn PsABio (NCT02627768), a prospective, observational study, patients with PsA that were prescribed first- to third-line ustekinumab or a TNFi, and remained on that drug for 3 years, were analysed for change in baseline in PROs (EuroQol-5 dimensions health state VAS [EQ-5D VAS], 12-item Psoriatic Arthritis Impact of Disease questionnaire [PsAID-12; range 0-10], Work Productivity and Activity Impairment for Psoriatic Arthritis questionnaire [WPAI; results expressed as a percentage for each domain]), and the association between PROs and WPAI with effectiveness endpoints, clinical disease activity index for psoriatic arthritis (cDAPSA), low disease activity (LDA)/remission, minimal disease activity (MDA) and very low disease activity (VLDA).ResultsIn 437 patients (mean age 49.1 years, 47.8% female), at 3 years, ustekinumab and TNFi treatment led to comparable improvements in EQ-5D VAS; mean change from baseline (95% confidence intervals [CI]) was 11.0 (6.5; 15.4) and 18.9 (14.0; 23.9), respectively. Both groups improved PsAID-12 after 3 years; mean change from baseline (95% CI) was -2.9 (-3.2; -2.5) and -3.5 (-3.9; -3.2), respectively. At baseline, due to their PsA, TNFi-treated patients had lower work productivity compared to ustekinumab-treated patients; mean productivity reduction (95% CI) was 58.8 [52.4; 65.2] and 43.3 [35.6; 51.1]. Over 3 years, TNFi-treated patients had a greater improvement in work productivity compared to ustekinumab-treated patients, ultimately leaving work productivity to be comparable between groups; mean improvement (95% CI) was 44.5% (38.4; 50.6) and 24.9% (15.8; 34.0), respectively. A similar trend was observed in activity impairment. Patients in both treatment groups who achieved effectiveness endpoints, cDAPSA LDA/remission, MDA, and VLDA had greater improvement in PROs and WPAI than patients who did not achieve these endpoints.ConclusionsAt 3 years, improvements in PROs following ustekinumab or TNFi treatment were generally comparable; however, TNFi-treated patients achieved a greater improvement in work productivity, although this group started from a lower baseline. Achievement of effectiveness endpoints, independent of treatment group, also improved PROs.Trial registrationClinicalTrials.gov, NCT02627768. Registered on 11 December 2015.

Project description:IntroductionThe aim of this work is to evaluate treatment persistence and clinical outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry.MethodsParticipants with PsA who initiated and persisted with on-label guselkumab use post-Food and Drug Administration (FDA) approval for active PsA (7/13/2020; subcutaneous 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (occurring through 3/31/2023) comprised the primary analysis population (On-Label Persisters). Hierarchical, multiplicity-controlled primary and secondary outcomes were mean (95% confidence interval) changes from baseline at 6 months in clinical Disease Activity Index for PsA (cDAPSA; primary), Physician Global Assessment (PGA) of arthritis and psoriasis (visual analog scale [VAS] 0-100), patient-reported pain (VAS 0-100), and percent body surface area with psoriasis (%BSA). Paired t tests determined changes that were statistically significantly different from 0 (α = 0.05).ResultsAmong 114 patients who initiated on-label guselkumab and had eligible baseline and 6-month visits, 90 (78.9%) had persistent use. Among these On-Label Persisters at baseline, mean duration of PsA symptoms = 13.6 years; mean cDAPSA, PGA, and patient-reported pain = 22.0, 42.3, and 57.0, respectively; 94.4% had a history of psoriasis (mean BSA 7.6%); and 18.9% and 73.3%, respectively, previously received 1 or ≥ 2 biologic/targeted synthetic disease-modifying antirheumatic drugs. The mean change (improvement) in cDAPSA was - 5.4 (- 8.5, - 2.3; p < 0.001) at 6 months. Significant mean improvements in PGA (- 19.0 [- 24.2, - 13.8]), patient-reported pain (- 9.1 [- 14.4, - 3.8]), and %BSA (- 5.1 [- 7.6, - 2.7]) were also observed (all p < 0.001).ConclusionsIn this real-world PsA population, generally characterized by longstanding, treatment-resistant, active disease at baseline, persistent guselkumab use in nearly 80% of patients with on-label use was accompanied by significant improvements in joint and skin symptoms and patient-reported pain at 6 months. These registry data support results from randomized clinical trials demonstrating the efficacy of guselkumab in improving PsA signs and symptoms.Trial registrationclinicaltrials.gov: NCT02530268.

Project description:BACKGROUND:Reductions in health-related quality of life (HRQoL) in patients with chronic kidney disease (CKD) are thought to be exacerbated by the low hemoglobin (Hb) levels that define anemia, a common complication of CKD. The current analysis evaluated the impact of anemia on HRQoL and work productivity in patients with non-dialysis dependent and dialysis-dependent CKD using real-world data. METHODS:Data were collected in France, Germany, Italy, Spain, the UK, the USA and China in 2012-2018 in the Adelphi Real World Disease Specific Programme™ for CKD, a large, cross-sectional, survey of physicians and their patients. Patients completed three patient-reported outcomes (PRO) instruments: the EuroQol 5-Dimension 3-level (EQ-5D-3?L), the Kidney Disease Quality of Life (KDQOL-36) instrument and the Work Productivity and Activity Impairment questionnaire. PROs were assessed by CKD stage and Hb levels, and regression analyses were performed with CKD stage and Hb level as independent variables and PROs as outcome variables, while adjusting for age, sex, CKD stage, comorbidities and cardiovascular risk. RESULTS:Overall, 5276 patients participated in the survey, including 28% stage 4 and 36% dialysis patients. Patients with lower Hb levels more often reported problems/issues on all EQ-5D-3?L domains (p <?0.0001). Regression analyses showed significant associations between lower Hb levels and the probability of low (<?0.8) EQ-5D-3?L utility scores (p <?0.0001) and low visual analog scale scores (p <?0.05), indicating poorer health status. Associations were seen even when adjusting for CKD stage and other potential confounding factors. Significant associations were observed between Hb level and the 12-Item Short-Form Health Survey (SF-12) Physical Component Summary, SF-12 Mental Component Summary and the three KDQOL-36 subscales (all p <?0.0001), and were confirmed using linear regression analyses adjusting for CKD stage and other potential confounders. Numerically greater work productivity losses and greater activity impairment were observed with lower Hb levels. CONCLUSIONS:Lower Hb levels worsen the impact of CKD on HRQoL, and are associated with lower work productivity in patients with CKD. Assessment and treatment of anemia should be recognized as a key component of integral CKD management throughout all stages of the disease.

Project description:IntroductionRheumatoid arthritis (RA), psoriatic arthritis (PsA) and psoriasis (PSO) are chronic inflammatory diseases that have a substantial impact on patients' health. This retrospective database study aimed to assess the epidemiology, comorbidities, diagnosis and treatment patterns of RA, PsA and PSO in the German population.MethodsData were extracted from the Deutsche Forschungsdatenbank für Abrechnungsinformationen der Krankenversicherung database from 2012 to 2016 for patients aged ≥ 18 years holding full health coverage in the reporting year at least. Diagnoses were defined according to International Classification of Diseases (ICD)-10 codes. Reported outcomes included prevalence and incidence rates, pre-defined comorbidities, diagnosing and treating physicians, and treatment exposure. A subgroup analysis was performed for women of childbearing age (females aged 18-45 years).ResultsThe prevalence rates of RA, PsA and PSO in Germany were consistent over the study period; by 2016 they were 0.4%, 0.3% and 2.1%, respectively, and in women of childbearing age they were 0.2%, 0.2% and 1.5%, respectively. RA, PsA and PSO were predominantly observed among patients aged > 45 years. RA and PsA were more prevalent in women, while PSO had an approximately equal gender distribution. Depressive episodes were the most frequently reported comorbidity in 2016 (RA: 25.7%; PsA: 25.1%; PSO: 17.8%), and this was similar in women of childbearing age (RA: 20.5%; PsA: 23.4%; PSO: 16.3%). Approximately 50% of patients with RA and PsA and 6% of patients with PSO were receiving systemic treatment in 2016, of which methotrexate (RA: 38.4%; PsA: 30.2%; PSO: 2.2%) was most common. Biologic therapies were the least frequently used treatment options (RA: 28.9%; PsA: 20.9%; PSO: 1.8%).ConclusionsThis analysis provides key epidemiological information for patients with RA, PsA and PSO, including in women of childbearing age, in Germany and highlights common comorbidities and that patients were likely receiving insufficient treatment for these diagnoses.
