Socioeconomic impact of treatment with biological disease-modifying antirheumatic drugs in Japanese patients with rheumatoid arthritis. Mod Rheumatol 2023; 34:27-36. [PMID: 36629510 DOI: 10.1093/mr/roac160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 12/13/2022] [Accepted: 12/17/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVES We evaluate the socioeconomic impact of treatment with biological and targeted synthetic disease-modifying antirheumatic drugs in Japanese patients with rheumatoid arthritis. METHODS We analysed data retrospectively from the prospective observational CorEvitas RA Japan Registry (March 2016-February 2020). Patients were categorised into paid workers (PWs) and home workers (HWs) and further based on drug classes. We assessed medication persistence, treatment outcomes, health care resource utilisation, and socioeconomic impact over 12 months, including direct (drugs and health care resource utilisation) and indirect (loss of productivity) costs. RESULTS Overall, 187 PWs and 114 HWs were identified. Over 12 months, medication persistence was high, treatment outcomes improved, and outpatient visits reduced in both groups. Following treatment initiation, direct costs increased, whereas indirect (loss of productivity) costs decreased in both groups. The unadjusted socioeconomic impact [Japanese yen (JPY)] increased across all drug classes in PWs (range: 29,700-151,700) and HWs (range: -28,700 to 83,000). Adjusted change in monthly socioeconomic impact was JPY 29,700-138,900 for PWs and JPY -28,000 to 92,800 for HWs. CONCLUSIONS In this study of Japanese patients with rheumatoid arthritis, the socioeconomic burden increased across patient groups and drug classes. The decrease in indirect (loss of productivity) costs partially offset the increase in direct costs.

Association between patient-reported outcomes and impairments in work and activity in patients with rheumatoid arthritis in clinical remission: A retrospective analysis using the IORRA database. Mod Rheumatol 2023; 33:899-905. [PMID: 36094815 DOI: 10.1093/mr/roac105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 08/02/2022] [Accepted: 08/30/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVES To explore the patient-reported outcomes (PROs) associated with work productivity and activity impairment (WPAI) in patients with rheumatoid arthritis (RA) in clinical remission. METHODS We enrolled patients with RA ≥18 years and with a simplified disease activity index ≤3.3 from the Institute of Rheumatology, Rheumatoid Arthritis data set collected in October 2017. The pain-visual analogue scale, patients' global assessment visual analogue scale (VAS), Japanese version of the Healthcare Assessment Questionnaire (J-HAQ) Disability Index, and duration of morning joint stiffness were selected as the PROs. To evaluate work productivity and activity, the WPAI for RA instrument (WPAI-RA) was used. To assess the contribution of each PRO to the WPAI-RA score, an analysis of variance model was constructed. RESULTS The mean age of the 2614 patients was 62.4 years; 85.1% were female. Median values of the WPAI-RA score were 1.1% for absenteeism, 6.5% for presenteeism, 7.4% for work impairment, and 10.2% for activity impairment. Morning joint stiffness contributed the most to absenteeism (18.0%), while pain-VAS contributed the most to presenteeism (57.4%), work productivity loss (51.1%), and daily activity impairment (53.7%). J-HAQ was the second most contributing factor to presenteeism (17.4%), work productivity loss (16.3%), and daily activity impairment (26.0%). CONCLUSIONS The pain-VAS and J-HAQ highly contributed to WPAI in patients with RA in clinical remission.

Expert Rev Pharmacoecon Outcomes Res 2023; 23:1027-1040. [PMID: 37604704 DOI: 10.1080/14737167.2023.2249610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 07/12/2023] [Accepted: 08/14/2023] [Indexed: 08/23/2023]
Abstract
OBJECTIVE To systematically review the cost-utility evidence of TNF-a-i treatment for rheumatoid arthritis (RA) and to estimate the pooled incremental net benefit (INBp). METHODS We selected economic evaluation studies reporting the cost-utility of TNF-a-i compared to other disease-modifying anti-rheumatic drugs (DMARDs) after a systematic search in PubMed, Embase, Scopus, and Tufts Medical Centers' cost-effective analysis registry. The results were reported as pooled INB in purchasing power parity-adjusted US dollars, along with 95% confidence intervals. We used GRADE quality assessment to present summaries of evidence and random-effects meta-analysis to synthesize cost-utility of TNF-a-i. RESULTS We included 86 studies for systematic review, of which 27 for meta-analysis. TNF-a-i is not cost-effective [$ -4,129(-6,789 to -1,469)] compared to other DMARDs but with high heterogeneity. There was no evidence of publication bias (p = 0.447). On separate analysis, TNF-a-i is not cost-effective [$ -4,805(-7,882 to -1,728)] compared to conventional synthetic DMARDs for RA treatment. GRADE assessment indicated very low confidence in pooled cost-utility results and likely presence of risk of bias on the overall ECOBIAS checklist in studies. CONCLUSION Based on the available evidence during the study period, TNF-a-i is not a cost-effective option for treating RA compared to other DMARDs. However, high heterogeneity and low confidence in GRADE quality assessment preclude the results from being generalizable.

Abstract
OBJECTIVE To assess the cost-effectiveness of biologic and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) in rheumatoid arthritis. METHODS We conducted three analyses: a lifetime analysis with a cohort model (Study A) and two short-term analyses (Studies B and C). Study A evaluated the incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year (QALY) gained from costs of standard treatments. Study B evaluated yearly costs per person achieving American College of Rheumatology (ACR) response (ACR20, ACR50, and ACR70), and Study C evaluated costs per person achieving previously defined claims-based effectiveness (equivalent to 28-joint Disease Activity Score ≤ 3.2). The proportion of ACR responders to the drugs of interest were determined by mixed treatment comparisons. Studies B and C estimated costs using a claims database. RESULTS In Study A, ICERs of all b/tsDMARDs were lower than 5.0 million Japanese yen (JPY) per QALY. In Study B, yearly costs per person with ACR50 response were lower for subcutaneous tocilizumab (TCZ-SC; 1.9 million JPY) and SC abatacept (2.3 million JPY). In Study C, costs per person were lower for TCZ-SC (1.3 million JPY) and intravenous TCZ (1.6 million JPY) and effectiveness rates were higher for intravenous TCZ (45.3%) and infliximab (43.0%). CONCLUSION The b/tsDMARDs with lower prices showed higher cost-effectiveness.

Cost-consequence of abatacept as first-line therapy in Japanese rheumatoid arthritis patients using IORRA real-world data. PLoS One 2022; 17:e0277566. [PMID: 36383610 PMCID: PMC9668164 DOI: 10.1371/journal.pone.0277566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 10/29/2022] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVES To investigate the cost-effectiveness of abatacept (ABA) as first-line (1L) therapy in Japanese rheumatoid arthritis (RA) patients using data from the Institute of Rheumatology, Rheumatoid Arthritis database. METHODS A decision-analytic model was used to estimate the cost per American College of Rheumatology response of at least 50% improvement (ACR50) responder and per patient in Clinical Disease Activity Index (CDAI) and Simplified Disease Activity Index (SDAI) remission from a Japanese healthcare payers' perspective over a 2-year time horizon. Clinical characteristics of patients on ABA-1L were matched with those of patients on ABA second or later line (2L+) or tumour necrosis factor inhibitor (TNFi)-1L directly or using propensity scores. Resource utilisation and medical costs were calculated from the Japan Medical Data Center claims database. Parameter uncertainty was addressed by sensitivity and subgroup analyses (age, treatment duration, Japanese version of Health Assessment Questionnaire [J-HAQ] score). RESULTS Incremental costs per member per month (ΔPMPM) for ABA-1L versus TNFi-1L and ABA-2L+ were -1,571 Japanese Yen (JPY) and 81 JPY, respectively. For ABA-1L versus TNFi-1L, ΔPMPM by ACR50 response was -11,715 JPY and by CDAI and SDAI remission 11,602 JPY and 47,003 JPY, respectively. Corresponding costs for ABA-1L were lower for all outcome parameters versus those for ABA-2L+. Scenario analyses showed that ABA-1L was cost-effective over TNFi-1L in patients <65 years for any outcome. Furthermore, ABA-1L was cost-effective over ABA-2L+ for all outcomes in patients with age <65 years, disease duration <5 years and J-HAQ ≥1.5. CONCLUSIONS ABA-1L demonstrated a favourable cost-effectiveness profile in RA patients, accruing savings for the Japanese healthcare payers.

Abstract
OBJECTIVES To explore patient-reported outcomes (PROs) related to quality of life (QOL) in patients with rheumatoid arthritis (RA) who achieved clinical remission. METHODS In the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) dataset, RA patients over 18 years old who met the simplified disease activity index (SDAI) remission criteria in April 2017 were enrolled in this analysis. Pain-visual analogue scale (pain-VAS) (0-100 mm), Patient's Global Assessment of Disease Activity (0-100 mm), Japanese version of Health Assessment Questionnaire, duration of morning joint stiffness, and fatigue (Checklist Individual Strength 8R [CIS]) were the tools used to evaluate PROs. To assess the contribution of each PRO to the European QOL-5 Dimensions-5 Level (EQ-5D-5L) score, analysis of variance was conducted. RESULTS Among the 2,443 patients with remission, the mean EQ-5D-5L was 0.9. The mean pain VAS and patients' global assessment of disease activity (Pt-GA) were 7.2 and 7.4, respectively. Factors that significantly contributed to the EQ-5D-5L were pain-VAS (48.8%), CIS score (18.1%), and Pt-GA (15.6%). Around 82.5% of the variance in EQ-5D-5L were explained by the three PROs. CONCLUSION This study demonstrated that pain-VAS, CIS, and Pt-GA were significant contributors to the EQ-5D-5L score in patients with RA who achieved SDAI remission.

Abstract
OBJECTIVES To evaluate the efficacy and safety of biosimilars compared with reference biological disease modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) as a part of the process of developing the 2020 update of the Japan College of Rheumatology guidelines for the management of RA. METHODS PubMed, Cochrane Library, and Japan Centra Revuo Medicina were searched for articles to conduct a systematic review (SR). The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS Twenty randomized controlled trials were included (biosimilars of infliximab, etanercept, and adalimumab). A meta-analysis revealed that the risk ratios (RRs) and 95% confidence intervals (CIs) of achieving the American College of Rheumatology 50% response (ACR50) at week 24 and serious adverse events (SAEs) for biosimilars compared with the reference bDMARDs were 1.04 (0.98-1.10) and 0.84 (0.61-1.18), respectively. The RRs of achieving ACR50 and SAEs at week 24 were respectively 0.93 (0.69-1.26) and 2.15 (0.55-8.35) in the patients who switched to biosimilars from the reference bDMARDs and 0.92 (0.76-1.12) and 1.41 (0.32-6.15) in those who continued the reference bDMARDs. CONCLUSION Biosimilars and reference bDMARDs were equally useful for the management of RA.

Front Pharmacol 2021; 12:700012. [PMID: 34737696 PMCID: PMC8562301 DOI: 10.3389/fphar.2021.700012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Accepted: 08/27/2021] [Indexed: 12/28/2022] Open
Abstract
Background: Big data and real-world data (RWD) have been increasingly used to measure the effectiveness and costs in cost-effectiveness analysis (CEA). However, the characteristics and methodologies of CEA based on big data and RWD remain unknown. The objectives of this study were to review the characteristics and methodologies of the CEA studies based on big data and RWD and to compare the characteristics and methodologies between the CEA studies with or without decision-analytic models. Methods: The literature search was conducted in Medline (Pubmed), Embase, Web of Science, and Cochrane Library (as of June 2020). Full CEA studies with an incremental analysis that used big data and RWD for both effectiveness and costs written in English were included. There were no restrictions regarding publication date. Results: 70 studies on CEA using RWD (37 with decision-analytic models and 33 without) were included. The majority of the studies were published between 2011 and 2020, and the number of CEA based on RWD has been increasing over the years. Few CEA studies used big data. Pharmacological interventions were the most frequently studied intervention, and they were more frequently evaluated by the studies without decision-analytic models, while those with the model focused on treatment regimen. Compared to CEA studies using decision-analytic models, both effectiveness and costs of those using the model were more likely to be obtained from literature review. All the studies using decision-analytic models included sensitivity analyses, while four studies no using the model neither used sensitivity analysis nor controlled for confounders. Conclusion: The review shows that RWD has been increasingly applied in conducting the cost-effectiveness analysis. However, few CEA studies are based on big data. In future CEA studies using big data and RWD, it is encouraged to control confounders and to discount in long-term research when decision-analytic models are not used.

Zhao J, Zhou W, Wu Y, Ji P, Yang L, Yan X, Zhang Z. The efficacy, safety and cost-effectiveness of hydroxychloroquine, sulfasalazine, methotrexate triple therapy in preventing relapse among patients with rheumatoid arthritis achieving clinical remission or low disease activity: the study protocol of a randomized controlled clinical Trial (ESCoRT study). BMC Med Inform Decis Mak 2021; 21:83. [PMID: 33663487 PMCID: PMC7934358 DOI: 10.1186/s12911-021-01449-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 02/18/2021] [Indexed: 11/25/2022] Open
Abstract
Background Tumor necrosis factor α inhibitors (TNFi) is effective for rheumatoid arthritis (RA) patients who fail to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). Because of high cost, the discontinuation is common but often lead to disease relapse. The study aims to investigate, if the combination therapy of csDMARDs is more effective in reducing disease relapse than methotrexate (MTX) monotherapy, and more cost-effective than continuing TNFi and MTX. Methods It will be a two-stage trial. In the first stage, all RA patients who failed to csDMARDs treatment [disease activity score 28 (DAS28)-CRP > 3.2] will receive MTX plus TNFi for no more than 12 weeks. Patients achieving DAS28-CRP < 3.2 during the first stage will be randomized into three groups at 1:1:1 ratio: (A) add hydroxychloroquine (HCQ) and sulfasalazine (SSZ) for the first 12 weeks and then remove TNFi but continue other treatments for the next 48 weeks; (B) maintain TNFi + MTX for 60 weeks; and (C) maintain TNFi + MTX for the first 12 weeks and then remove TNFi but continue MTX monotherapy for the next 48 weeks. The primary outcome will be disease relapse (DAS28-CRP increases by at least 0.6 and > 3.2). Secondary outcomes will include the incremental cost per reducing 1 case of relapse; patient reported intolerance to the treatment; adverse events; change of mean disease activity measured by DAS28, clinical disease activity index (CDAI) and simplified disease activity index (SDAI); the proportion of modified Sharp score increase < 0.3; ultrasound-detected remission in hands; Health Assessment Questionnaire Disability Index (HAQ-DI) and health related quality of life [the five-level EuroQol-5D (EQ-5D-5L) and short form-6D (SF-6D)]. Discussion The aim of this trail will be to seek effective treatment options of preventing relapse of RA. The results of the current study may provide an instructive recommendation for more economical application of TNFi treatment in RA. Trial registration NCT, NCT02320630.

Abstract
OBJECTIVES Malignant rheumatoid arthritis (MRA) is defined as rheumatoid arthritis (RA) with systemic vasculitis or other severe extra-articular manifestations. Japan has a nationwide database for MRA. We analyzed the characteristics of Japanese patients with MRA based on data from the Ministry of Health, Labour and Welfare (MHLW). METHODS We were permitted to use data on 43,108 patients who were registered in the MHLW database from 2003 to 2013. RESULTS Median age was 65 (interquartile range, 57-72) years. Patients consisted of 71% females. Proportions of patients who had or had experienced interstitial pneumonia and pleuritis were increased, episcleritis was stable, and other MRA manifestations were decreased over time. The number of positive symptoms per patient also decreased over time. The median dose of glucocorticoid, percentage of patients undergoing surgery, and use of non-steroidal anti-inflammatory drugs and apheresis decreased year by year. Steinbrocker stage and class improved over time. Median C-reactive protein levels and erythrocyte sedimentation rate also decreased. Regarding social productivity levels of patients with MRA, the proportion of patients who were working or working from home increased and the proportion of patients recuperating or hospitalized decreased. CONCLUSION In patients with MRA, disease activity decreased and social productivity improved from 2003 to 2013.
