Cost of hemophilia A in Brazil: a microcosting study. HEALTH ECONOMICS REVIEW 2024; 14:62. [PMID: 39105856 PMCID: PMC11305066 DOI: 10.1186/s13561-024-00539-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Accepted: 07/16/2024] [Indexed: 08/07/2024]
Abstract
BACKGROUND Patients with Hemophilia are continually monitored at treatment centers to avoid and control bleeding episodes. This study estimated the direct and indirect costs per patient with hemophilia A in Brazil and evaluated the cost variability across different age groups. METHODS A prospective observational research was conducted with retrospective data collection of patients assisted at three referral blood centers in Brazil. Time-driven Activity-based Costing method was used to analyze direct costs, while indirect costs were estimated based on interviews with family and caregivers. Cost per patient was analyzed according to age categories, stratified into 3 groups (0-11;12-18 or older than 19 years old). The non-parametric Mann-Whitney test was used to confirm the differences in costs across groups. RESULTS Data from 140 hemophilia A patients were analyzed; 53 were 0-11 years, 29 were 12-18 years, and the remaining were older than 19 years. The median cost per patient per year was R$450,831 (IQR R$219,842; R$785,149; $174,566), being possible to confirm age as a cost driver: older patients had higher costs than younger's (p = 0.001; median cost: 0-11 yrs R$299,320; 12-18 yrs R$521,936; ≥19 yrs R$718,969). CONCLUSION This study is innovative in providing cost information for hemophilia A using a microcosting technique. The variation in costs across patient age groups can sustain more accurate health policies driven to increase access to cutting-edge technologies and reduce the burden of the disease.

Abstract
Background Hemophilia-associated bleeding and resultant joint pain and mobility restrictions can predispose patients to poor health-related quality of life (HRQoL). Therefore, efficacy of a treatment needs to address more than just annualized bleed rates. Objectives Describe the evolution of HRQoL, pain, and activity in patients with hemophilia A, treated with efmoroctocog alfa prophylaxis. Design A post hoc analysis from Kids A-LONG (NCT01458106), A-LONG (NCT01181128), and long-term extension study ASPIRE (NCT01454739) assessed change in pain and activity-related patient-reported outcomes (PROs). Methods Physical health, pain, and HRQoL were assessed by PROs for a cumulative treatment duration of up to ~6 years. The primary endpoint was change from baseline in EuroQoL (EQ)-5D and Haemophilia Quality of Life Questionnaire (Haem-A-QoL). Results 118 adult/adolescents and 71 pediatric patients were included. The proportion of adults and adolescents reporting no problem in the EQ-5D analysis of 'pain/discomfort' significantly increased from A-LONG baseline (35.04%; 41/117) to ASPIRE month 30 (44.68%; 21/47; p = 0.024). Mean (standard deviation) Haem-A-QoL subdomain scores for 'feeling' and 'physical health' at A-LONG baseline improved by -3.24 (15.13; p = 0.018) and -3.85 (23.07; p = 0.047), respectively, at study end. Proportion of pediatric patients reporting no problem on the EQ-5D analysis of 'pain/discomfort', significantly increased from A-LONG baseline (75.0%; 42/56) to ASPIRE baseline (95.56%; 43/45; p = 0.046). Satisfaction levels for pediatric patients were high at A-LONG baseline and maintained until study end. Conclusion Long-term efmoroctocog alfa prophylaxis reduces pain and improves HRQoL in adult and adolescent patients with hemophilia A. In pediatric patients, it reduces perceived pain and maintains satisfaction levels. Trial registration NCT01458106, NCT01181128, NCT01454739.

Abstract
Claims data are increasingly discussed to evaluate health care for rare diseases (resource consumption, outcomes and costs). Using haemophilia A (HA) as a use case, this analysis aimed to generate evidence for the aforementioned information using German Statutory Health Insurance (SHI) claims data. Claims data (2017-2019) from the German SHI 'AOK Bayern - Die Gesundheitskasse' were used. Patients with ICD-10-GM codes D66 and HA medication were included in descriptive analyses. Severity levels were categorized according to HA medication consumption. In total, 257 patients were identified: mild HA, 104 patients (mean age: 40.0 years; SD: 22.9); moderate HA, 17 patients, (51.2 years; SD: 24.5); severe HA, 128 patients, (34.2 years; SD: 18.5). There were eight patients categorized with inhibitors (37.8 years; SD: 29.6). Psychotherapy was reported among 28.8% (mild) to 32.8% (severe) of patients. Joint disease was documented for 46.2% (mild) to 61.7% (severe) of patients. Mean direct costs per patient per year were 1.34× for mild, 11× for moderate, 81× higher for severe HA patients and 223× higher for inhibitor patients than the mean annual expenditure per AOK Bayern insurant (2019). German SHI data provide comprehensive information. The patient burden in HA is significant with respect to joint disease and psychological stress regardless of the HA severity level. The cost of HA care for patients is high. Large cost ranges suggest that the individual situation of a patient must be considered when interpreting costs. The main limitation of SHI data analysis for HA was the lack of granularity of ICD codes.

Cost-Effectiveness of Recombinant Factor IX Fc Prophylaxis and Recombinant Factor IX On-Demand Treatment in Patients with Haemophilia B Without Inhibitors. Adv Ther 2024; 41:2307-2323. [PMID: 38652439 PMCID: PMC11133064 DOI: 10.1007/s12325-024-02841-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 03/11/2024] [Indexed: 04/25/2024]
Abstract
INTRODUCTION Recombinant factor IX (rFIX) and recombinant FIX Fc fusion protein (rFIXFc) are standard half-life and extended half-life FIX replacement therapies, respectively, and represent established treatment options indicated for adults and children with haemophilia B. These FIX replacement therapies can be administered as prophylaxis (to prevent bleeding) or 'on-demand' (to stop bleeding). This analysis aimed to estimate the cost-effectiveness of once-weekly prophylaxis with rFIXFc versus on-demand treatment with rFIX in patients with haemophilia B without inhibitors in the Italian healthcare setting. METHODS A Markov model was developed to assess a hypothetical cohort of adolescent or adult male patients (≥ 12 years) with haemophilia B (FIX level of ≤ 2 IU/dL) without inhibitors. Model inputs were derived from the pivotal phase 3 clinical studies for rFIXFc and rFIX, published literature and assumptions when published data were unavailable. The model employed a lifelong time horizon with 6-monthly transitions between health states, and it estimated total costs, total quality-adjusted life years (QALYs), number of bleeds, number of surgeries and incremental cost-effectiveness ratio. RESULTS rFIXFc prophylaxis was associated with lower total costs per patient (€5,308,625 versus €6,564,510) and greater total QALYs per patient (15.936 versus 11.943) compared with rFIX on-demand; rFIXFc prophylaxis was therefore the dominant treatment strategy. The model also demonstrated that rFIXFc prophylaxis was associated with fewer incremental bleeds (- 682.29) and surgeries (- 0.39) compared with rFIX on-demand. CONCLUSIONS rFIXFc prophylaxis provides improved health outcomes and lower costs, and represents a cost-effective treatment option compared with rFIX on-demand for adolescent and adult male patients with haemophilia B. This comparative assessment of cost-effectiveness should help to inform both clinicians and healthcare policy makers when making treatment decisions for patients with haemophilia B.

Abstract
Background Interest in the financial burden of informal caregivers has been growing. Unfortunately, it remains unclear which method(s) should be used when quantifying this burden. Purpose We conducted a scoping review aimed at identifying which methods have been used to conduct such work and quantified their performance. We were also interested in examining how sex and gender considerations were considered within selected studies. Data Sources Using a standardized approach, we identified studies published between 2012 and 2022 that aimed to document the financial burden of caregivers to child and adolescent patients. Our search strategy was applied to the MEDLINE, Embase, CINHAL, and Academic Search Premier databases. Study Selection Manuscript selection was performed by pairs of reviewers. Data Extraction Data extraction was performed by one reviewer with a second reviewer performing quality control. Results were reported using a narrative approach. Data Synthesis We identified 9801 unique citations, of which 200 were included in our review. Selected studies covered various disease area (eg, infection/parasitic diseases [n = 31, 16%]) and included quantitative (n = 180, 90%), qualitative (n = 4, 2%) and mixed study designs (n = 16, 8%). Most studies (n = 182, 91%) used questionnaires/surveys, either alone or in combination with other methods, to assess caregivers' financial burden. Less than half (n = 93, 47%) of studies reported on caregivers' sex and none reported on their gender. Conclusion We conducted an unrestricted review of published studies examining caregiver's financial burden which allowed us to identify general methodological trends observed in this literature. We believe this work may help improve future studies focusing on this important issue.

Abstract
BACKGROUND Haemophilia A carries a substantial healthcare burden, affecting health-related quality of life (HRQoL). The Cost of Haemophilia in Men: a Socioeconomic Survey II (CHESS II), a retrospective real-world study, characterised the burden of haemophilia and its impact on HRQoL and work productivity. The current analysis explored the impact of bleeding events on HRQoL and work productivity in Europe. This analysis focused on data collected from males aged 18 to 64 years with haemophilia A without inhibitors who were receiving replacement factor products or a monoclonal antibody and were not participating in a clinical trial at the time of study recruitment. Descriptive statistics were analysed using scores from EuroQoL's EQ-5D-5L index and EQ-VAS analogue scale and the Work Productivity and Activity Index Specific Health Problem (WPAI:SHP) percentage scores stratified by the number of annual bleeding events (ABs) 0, 1, 2, 3-4, or ≥ 5. RESULTS Of 918 males with haemophilia A in CHESS II, 318 met inclusion criteria and had data available for HRQoL measures; mean age (SD) was 33.8 (12.1) years and 96% were White. Mean (SD) ABs of 2.7 (2.9) occurred over the preceding 12 months: 20% had 3 or 4 ABs; 17% had ≥ 5 ABs. Mean EQ-5D-5L index scores for patients with 0, 1, 2, 3-4, or ≥ 5 ABs were 0.92, 0.76, 0.76, 0.71, and 0.56, respectively. Mean (SD) EQ-VAS scores were 86.9 (13.6), with 0 ABs versus 69.5 (19.1) for 3 or 4 ABs and 61.2 (17.2) for ≥ 5 ABs. Mean percentage of overall work productivity loss on the WPAI:SHP questionnaire ranged from 9.70 to 0 ABs to 47.65 for ≥ 5 ABs. CONCLUSIONS In this European sample of adult men with haemophilia A, HRQoL and work productivity scores were lower among those reporting more AB events. Bleeding burden appears to affect HRQoL and productivity; however, this cross-sectional analysis limits the ability to draw firm conclusions on causality.

Abstract
INTRODUCTION Prophylactic clotting factor infusion regimens to prevent bleeding and joint deformity has become the standard of care in severe hemophilia A patients. AIM To assess low-dose factor prophylaxis in our population as an alternative approach to managing severe hemophilia A. METHODS A prospective cohort study that included 68 hemophilia A patients divided into two groups, i.e., Prophylaxis and on-demand. The two groups were compared for annualized bleeding rate (ABR), hospitalization, units of factor VIII (FVIII) infused, or plasma products transfused, i.e., fresh frozen plasma (FFP) and cryoprecipitate (CP), and development of FVIII inhibitors. RESULTS Of the 68 patients recruited in this study, 25 (36.7%) were in the prophylaxis group, and 43(63.3%) were in the on-demand group. The on-demand group presented a higher median-IQR ABR [8(20-3) vs. 5(10-1.5), p-value 0.024], several hospitalizations (39.7% vs. 0, p-value 0.001), and inhibitor development (9.3% vs. 0, p-value 0.289) compared to the prophylaxis group. The prophylaxis approach demonstrated a significant negative correlation of ABR with FVIII prophylaxis (r=-0484, p=value=0.014). Moreover, no hospitalizations or inhibitor development was observed in the prophylaxis group. The estimated annual consumption of FVIII was 328 IU/kg/year in the on-demand group and 1662.6 IU/kg/year in the prophylaxis group. However, a highly significant difference in plasma product utilization was observed between the two groups, i.e., p-value <0.001 and 0.038 for FFP and CP, respectively. CONCLUSION Low-dose factor prophylaxis resulted in improved outcomes compared to on-demand treatment in terms of ABR, joint bleeding, hospitalization, and the development of inhibitors. This treatment approach should be adopted as an economically feasible alternative to high-dose Prophylaxis in resource-constrained countries.

Abstract
BACKGROUND: Hemophilia A (HA) is a rare, inherited, serious bleeding disorder characterized by a deficiency of blood clotting factor VIII (FVIII). HA is associated with considerable economic burden. OBJECTIVE: To identify, review, and summarize published studies on the health care resource use and costs of managing HA in the United States using a targeted literature review. METHODS: A comprehensive and targeted literature search was conducted in Embase, MEDLINE, and Cochrane Database of Systematic Reviews covering the period 2010 to 2022. We supplemented the search by searching gray literature (relevant abstracts, posters, and presentations of relevant scientific conferences from the past 6 years [2016 to 2022], reference lists, the Institute for Clinical and Economic Review reports, and other sources). Eligibility criteria were developed based on the population, interventions, comparators, and outcomes framework. For comparability, costs were adjusted to 2021 US dollars. RESULTS: A total of 40 publications, including 17 full-text papers, 21 abstracts, and 2 Institute for Clinical and Economic Review reports, met eligibility criteria. Total annual health care costs per patient ranged from $213,874 to $869,940 and are mainly driven by the cost and intensity of prophylaxis with FVIII replacement concentrates, bypassing agents, and, most recently, emicizumab. Generally, we observed substantial heterogeneity in estimated treatment costs for HA, which varied depending on HA severity, treatment type and intensity, age, weight, and inhibitor status. Patients with inhibitors incurred much higher costs, but annual FVIII treatment costs are increasing over time among a subset of adult patients without inhibitors. Only 2 studies reported indirect costs; these were $13,220 and $27,978 annually among patients without and with inhibitors, respectively. Parents of children with HA spent $8,252 on non-mental health services and $258 on mental health services annually. CONCLUSIONS: The annual health care costs of managing HA are substantial and vary widely, depending on the study population definitions and intensity of prophylaxis. Total health care costs are dominated by the cost of prophylaxis. Indirect costs are also important. More robust studies in various settings, subpopulations, and assessing the impact of emerging therapies are required to fully elucidate the changing societal and economic impact, particularly regarding indirect costs and productivity loss for individuals living with HA. DISCLOSURES: Drs Solari and Thornhill are employees of Spark Therapeutics and Roche Group Shareholders. Ms Chen and Drs Cheng and Sullivan are employees of Curta, Inc. Spark Therapeutics paid Curta, Inc., to conduct the literature search. This study was funded by Spark Therapeutics. Spark Therapeutics was involved in the study design, collection, analysis and interpretation of data, article review, and the decision to submit the report for publication. Medical writing support was provided by Ashfield MedComms, an Inizio company.

Methods A longitudinal study was conducted between 2017 and 2018 in Tabriz (Iran) using the Persian version of the Work Productivity and Activity Impairment (WPAI) questionnaire. Direct and indirect costs associated with asthma were estimated based on the societal perspective, prevalence-based approach, and bottom-up method. Annual indirect costs were estimated using the human capital (HC) method. The structural equation model was used to evaluate the relationship between costs, sex, and asthma severity. Results A total of 621 patients with asthma were enrolled in the study. Significant differences were found between female and male patients for the mean cost of radiology (P=0.006), laboratory (P=0.028), and diagnostic (P=0.017) tests at baseline, and for laboratory (P=0.012), and diagnostic (P=0.027) tests at one-year follow-up. The more severe asthma, the more significant the costs for annual physician office visits (P=0.040) and medications (P=0.013). As asthma severity increased, significantly higher expenditures were observed in women for days lost from work at baseline (P=0.009) and one-year follow-up (P=0.001), and in men for productivity loss at work due to impairment at baseline (P=0.045). A significant association between indirect costs and the cost of impairment-related lost productivity at work (β=3.29, P<0.001), and between severe asthma and indirect costs (β=32.36, P<0.001) was observed. Conclusion High costs are incurred by Iranian asthma patients, especially because of impairment-related productivity loss at work associated with asthma exacerbation.

Haemophilia 2023; 29:505-512. [PMID: 36639952 DOI: 10.1111/hae.14741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 12/02/2022] [Accepted: 12/20/2022] [Indexed: 01/15/2023]
Abstract
INTRODUCTION In chronic diseases, disease-related distress can impact disease outcomes. Distress and haemophilia-related distress has been demonstrated in people with haemophilia (PwH). The association of haemophilia-related distress on disease outcomes among PwH is unknown. AIM To study the association of haemophilia-related distress with haemophilia specific outcomes, including adherence to prophylactic therapy, the presence of a target joint, healthcare utilization and work-impairment. METHODS In a cross-sectional study, adults with haemophilia A or B were enrolled in a study to validate the haemophilia-related distress questionnaire (HRDq). In this planned analysis, univariate and multivariate associations between the HRDq total score and disease outcomes were explored. RESULTS The 114 participants in this analysis were male, mostly with haemophilia A (92%) and severe disease (52%) with a median age of 31.9 years. On univariate analysis, HRDq total score (5-point change) was associated with the presence of a target joint (P = .002), high healthcare utilization (P = .011), poor adherence (P = .033) and work-impairment (P ≤ .001). After adjustment for age, race, severity and other potential confounders, adherence (aβ 0.33, 95% CI .17, .49) and work-impairment (aβ 4.69, 95% CI 3.27-6.1) remained statistically significantly associated with HRDq total score. CONCLUSION Haemophilia-related distress is associated with poor adherence to factor prophylaxis and work-impairment. The direction of the association (causation) is yet to be determined and requires future study.

Cost-effectiveness of recombinant factor VIII Fc versus emicizumab for prophylaxis in adults and adolescents with haemophilia A without inhibitors in the UK. Eur J Haematol 2023; 110:262-270. [PMID: 36398467 PMCID: PMC10107896 DOI: 10.1111/ejh.13901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 11/10/2022] [Accepted: 11/14/2022] [Indexed: 11/19/2022]
Abstract
INTRODUCTION The economic and clinical burden of haemophilia A is high. Primary prophylaxis with factor VIII replacement therapy is the recognised standard of care, but the emergence of non-factor therapies, such as emicizumab, is extending treatment options for people with haemophilia A. AIM There are currently no direct comparisons of efficacy or cost between recombinant factor FVIII Fc-fusion protein efmoroctocog alfa (a recombinant factor FVIII Fc-fusion protein referred to herein as rFVIIIFc) and emicizumab; therefore, a cost-effectiveness model was developed to compare prophylactic treatment with rFVIIIFc versus emicizumab in patients with haemophilia A without inhibitors in the UK. METHODS The cost-effectiveness model was based on a matching-adjusted indirect comparison and included male patients, aged ≥12 years, with haemophilia A without inhibitors. The model was designed as a Markov process with a flexible lifelong time horizon, and cost-effectiveness was presented as an incremental cost-effectiveness ratio. Base-case analysis and sensitivity analyses (including scenario analyses, one-way deterministic sensitivity analysis [DSA] and probability sensitivity analysis [PSA]) were performed using the following treatment strategies: individualised prophylaxis with rFVIIIFc and prophylaxis with emicizumab administered once weekly (scenario analyses used regimens of once every 2 weeks or once every 4 weeks). RESULTS Base-case analysis, DSA and PSA indicated that, compared with emicizumab administered once weekly, rFVIIIFc individualised prophylaxis was the dominant treatment strategy, with lower costs, a greater number of quality-adjusted life years, and a lower number of bleeds. CONCLUSIONS rFVIIIFc has proven efficacy and is cost-effective compared with emicizumab, providing clinicians with a viable treatment option to improve the health outcomes for adults and adolescents with haemophilia A in the UK.

Abstract
INTRODUCTION In factor VIII (FVIII) prophylaxis for haemophilia A, cost comparisons have used price per international unit (IU) based on the once reasonable assumption of equivalent outcome per IU. Now, with several extended half-life (EHL) products available, new outcome-oriented ways to compare products are needed. Area under the curve (AUC) quantifies FVIII levels over time after infusion providing comparable data. AIM To develop a decision analytical model for making indirect comparisons of FVIII replacement products based on AUC. METHODS A literature search identified 11 crossover studies with relevant pharmacokinetic data. A common comparator FVIII level curve was calculated using pooled data from selected studies. Absolute curves for other products were estimated based on relative differences to the common comparator (% difference vs the anchor). Three scenarios were investigated: (1) Kogenate® versus Kovaltry® and Jivi® ; (2) Advate® versus Elocta® , NovoEight® , Kovaltry, Adynovate® , Afstyla® , and ReFacto® ; and (3) Jivi versus Elocta, Adynovate, and Kogenate. Sensitivity analyses investigated effects of assay type and dose. RESULTS In scenario 1, Jivi (+50%) and Kovaltry (+14%) showed larger AUCs versus Kogenate. In scenario 2, EHL products, Elocta and Adynovate, had the largest AUC (+64% and +58%, respectively) versus Advate. Compared with all other products in scenario 3, Jivi had the largest AUC by +13%-28%. CONCLUSION This analysis concludes that EHL products differ in relative AUC, have a larger AUC compared with standard half-life, and thus, different FVIII levels over time after infusion. This model may aid decision makers in the absence of head-to-head data.

Abstract
AIMS To compare healthcare costs in patients with non-inhibitor hemophilia A treated with Rurioctocog Alfa Pegol (FVIII-PEG) versus Antihemophilic Factor (Recombinant), FC Fusion Protein (rFVIIIFc). MATERIALS AND METHODS Administrative claims data from the Merative MarketScan Commercial (Commerical) and Medicaid (Medicaid) databases were used for these analyses. Males with non-inhibitor hemophilia A treated with FVIII-PEG or rFVIIIFc from 1 January 2016 to 31 March 2021 were identified (earliest treatment = index). Patients were required to have continuous database enrollment for six months before and after the index date. Follow-up was variable in length until disenrollment or study end. All-cause and hemophilia-related healthcare costs were reported per-patient per month [PPPM] and the average weekly dose during follow-up was compared between treatment groups. Generalized linear regressions were used to estimate multivariable-adjusted differences in total costs and weekly dosage in the two treatment groups. RESULTS A total of 131 FVIII-PEG (66 Commercial; 65 Medicaid) and 204 rFVIIIFc (111 Commercial; 93 Medicaid) patients were eligible. Mean age was 20.5 and 24.4 for FVIII-PEG and rFVIIIFc in Commercial and 14.9 and 17.5 for FVIII-PEG and rFVIIIFc in Medicaid. PPPM mean (standard deviations [SD]) total healthcare costs in Commercially insured patients were $35,868 [$21,717] for FVIII-PEG vs $40,424 [$25,882] for rFVIIIFc. Costs in Medicaid were $27,495 [$23,243] for FVIII-PEG vs $30,237 [$28,430] for rFVIIIFc. After adjusting for baseline characteristics, the costs for rFVIIIFc (vs FVIII-PEG) were higher by $5,215 in Commercial and $3,895 in Medicaid, but the differences were not statistically significant (p > 0.05). Similar findings were observed for hemophilia-specific healthcare costs. The adjusted mean weekly dose was 6,047 vs 4,892 IU, p = 0.21 for FVIII-PEG vs rFVIIIFc in Commercial and 5,549 vs 7,228 IU, p = 0.07 for FVIII-PEG vs rFVIIIFc in Medicaid. CONCLUSIONS Healthcare costs and treatment dosing were similar (p > 0.05) for non-inhibitor hemophilia A patients treated with FVIII-PEG and rFVIIIFc.

Abstract
Introduction Placenta-derived mesenchymal cells (PLCs) endogenously produce FVIII, which makes them ideally suited for cell-based fVIII gene delivery. We have previously reported that human PLCs can be efficiently modified with a lentiviral vector encoding a bioengineered, expression/secretion-optimized fVIII transgene (ET3) and durably produce clinically relevant levels of functionally active FVIII. The objective of the present study was to investigate whether CRISPR/Cas9 can be used to achieve location-specific insertion of a fVIII transgene into a genomic safe harbor, thereby eliminating the potential risks arising from the semi-random genomic integration inherent to lentiviral vectors. We hypothesized this approach would improve the safety of the PLC-based gene delivery platform and might also enhance the therapeutic effect by eliminating chromatin-related transgene silencing. Methods We used CRISPR/Cas9 to attempt to insert the bioengineered fVIII transgene "lcoET3" into the AAVS1 site of PLCs (CRISPR-lcoET3) and determined their subsequent levels of FVIII production, comparing results with this approach to those achieved using lentivector transduction (LV-lcoET3) and plasmid transfection (Plasmid-lcoET3). In addition, since liver-derived sinusoidal endothelial cells (LSECs) are the native site of FVIII production in the body, we also performed parallel studies in human (h)LSECs). Results PLCs and hLSECs can both be transduced (LV-lcoET3) with very high efficiency and produce high levels of biologically active FVIII. Surprisingly, both cell types were largely refractory to CRISPR/Cas9-mediated knockin of the lcoET3 fVIII transgene in the AAVS1 genome locus. However, successful insertion of an RFP reporter into this locus using an identical procedure suggests the failure to achieve knockin of the lcoET3 expression cassette at this site is likely a function of its large size. Importantly, using plasmids, alone or to introduce the CRISPR/Cas9 "machinery", resulted in dramatic upregulation of TLR 3, TLR 7, and BiP in PLCs, compromising their unique immune-inertness. Discussion Although we did not achieve our primary objective, our results validate the utility of both PLCs and hLSECs as cell-based delivery vehicles for a fVIII transgene, and they highlight the hurdles that remain to be overcome before primary human cells can be gene-edited with sufficient efficiency for use in cell-based gene therapy to treat HA.

Abstract
Protein based therapeutics have successfully improved the quality of life for patients of monogenic disorders like hemophilia, Pompe and Fabry disease. However, a significant proportion of patients develop immune responses towards intravenously infused therapeutic protein, which can complicate or neutralize treatment and compromise patient safety. Strategies aimed at circumventing immune responses following therapeutic protein infusion can greatly improve therapeutic efficacy. In recent years, antigen-based oral tolerance induction has shown promising results in the prevention and treatment of autoimmune diseases, food allergies and can prevent anti-drug antibody formation to protein replacement therapies. Oral tolerance exploits regulatory mechanisms that are initiated in the gut associated lymphoid tissue (GALT) to promote active suppression of orally ingested antigen. In this review, we outline general perceptions and current knowledge about the mechanisms of oral tolerance, including tissue specific sites of tolerance induction and the cells involved, with emphasis on antigen presenting cells and regulatory T cells. We define several factors, such as cytokines and metabolites that impact the stability and expansion potential of these immune modulatory cells. We highlight preclinical studies that have been performed to induce oral tolerance to therapeutic proteins or enzymes for single gene disorders, such as hemophilia or Pompe disease. These studies mainly utilize a transgenic plant-based system for oral delivery of antigen in conjugation with fusion protein technology that favors the prevention of antigen degradation in the stomach while enhancing uptake in the small intestine by antigen presenting cells and regulatory T cell induction, thereby promoting antigen specific systemic tolerance.

Abstract
Hemophilia A (factor VIII [FVIII] deficiency) and hemophilia B (factor IX [FIX] deficiency) are the X-linked recessive bleeding disorders that clinically manifest with recurrent bleeding, predominantly into muscles and joints. In its severe presentation, when factor activity is less than 1% of normal, hemophilia presents with spontaneous musculoskeletal bleeds and may progress to debilitating chronic arthropathy. Management of hemophilia has changed profoundly in the past decades. From on-demand to prophylactic factor concentrate replacement, the treatment goal shifted from controlling bleeds to preventing bleeds and improving quality of life. In this new scenario, gene therapy has arisen as a paradigm-changing therapeutic option, a one-time treatment with the potential to achieve sustained coagulation FVIII or FIX expression even within the normal range. This review discusses the critical impact of adeno-associated virus (AAV) gene transfer in hemophilia care, including the recent clinical outcomes, changes in disease perceptions, and its treatment burden. We also discuss the challenging scenario of the AAV-directed immune response in the clinical setting and potential strategies to improve the long-lasting efficacy of hemophilia gene therapy efficacy.

Abstract
Background Treatment of congenital hemophilia A (HA) in Japan has greatly improved with the widespread adoption of prophylactic factor (F)VIII concentrates. However, it is unknown if this has translated into a real-world reduction in disease and treatment burden. Objectives To describe HA disease burden in Japan based on information from two medical information databases, JMDC and Real World Data Co., Ltd. (RWD). Methods Eligible individuals were diagnosed with congenital HA and prescribed FVIII concentrates, bypassing agents, or emicizumab. Treatment patterns and disease burden data were derived from health insurance claims and electronic medical records. Results Data on 459 people with HA were retrospectively collected from 2005 to 2020 in the JMDC database (median [min, max] of 37 [2, 186] months of available records), and 229 people with HA from 1985 to 2020 in the RWD database (median [min, max] of 154 [0, 409] months of available records). Mean (standard deviation) ages at the time of the first record were 25.0 (16.8) years (JMDC) and 19.2 (20.3) years (RWD). In the JMDC database, mean monthly FVIII dose increased from 2201 IU in 2005 to 8239 IU in 2013 to 11,377 IU in 2019; HA-related drug costs increased accordingly. Mean (95% confidence interval) annual outpatient and out-of-hours visits decreased slightly between 2013 and 2019 (outpatient visits: from 22.9 [16.8-29.0] to 14.3 [12.6-16.1] per person; out-of-hours visits: from 1.3 [0.2-2.5] to 0.6 [0-1.4]). There was no change in mean number of hospitalizations. Conclusions Challenges remain in HA, including treatment burden, outpatient visits, and hospitalizations.

Abstract
Historically, the standard of care for hemophilia A has been intravenous administration of exogenous factor VIII (FVIII), either as prophylaxis or episodically. The development of emicizumab, a humanized bispecific monoclonal antibody mimicking activated FVIII, was a subsequent advance in treatment. However, both exogenous FVIII and emicizumab require repeated and lifelong administration, negatively impacting patient quality of life. A recent breakthrough has been the development of gene therapy. This allows a single intravenous treatment that could result in long-term expression of FVIII, maintenance of steady-state plasma concentrations, and minimization (or possibly elimination) of bleeding episodes for the recipient's lifetime. Several gene therapies have been assessed in clinical trials, with positive outcomes. Valoctocogene roxaparvovec (an adeno-associated viral 5-based therapy encoding human B domain-deleted FVIII) is expected to be the first approved gene therapy in European countries, including Italy, in 2022. Some novel challenges exist including refining patient selection criteria, managing patient expectations, further elucidation of the durability and variability of transgene expression and long-term safety, and the development of standardized 'hub and spoke' centers to optimize and monitor this innovative treatment. Gene therapy represents a paradigm shift, and may become a new reference standard for treating patients with hemophilia A.

Abstract
Detailed information on the onset, frequency, and severity of bleeding in nonsevere hemophilia is limited. We aimed to assess the bleeding phenotype of persons with nonsevere hemophilia and to analyze the association between baseline factor VIII/IX (FVIII/IX) levels and the joint bleeding rate. In the DYNAMO (Dynamic Interplay Between Bleeding Phenotype and Baseline Factor Level in Moderate and Mild Hemophilia A and B) study, an international multicenter cohort, we included males with nonsevere hemophilia (FVIII/IX, 0.02-0.35 IU/mL) aged 12 to 55 years. Information on age at first treated (joint) bleed, annual bleeding rates (ABRs), and annual joint bleeding rates (AJBRs) was collected from the medical files. The association between baseline FVIII/IX levels and the joint bleeding rate was assessed by using a frailty model for recurrent events. In total, 304 persons (70 with moderate hemophilia and 234 with mild hemophilia) were included. The median age was 38 years (interquartile range [IQR], 25-49 years), and the median baseline FVIII/IX level was 0.12 IU/mL (IQR, 0.05-0.21 IU/mL). In total, 245 (81%) persons had experienced at least 1 bleed, and 156 (51%) had experienced at least 1 joint bleed. The median age at first bleed and first joint bleed was 8 and 10 years, respectively. The median ABR and AJBR was 0.2 (IQR, 0.1-0.5) and 0.0 (IQR, 0.0-0.2). From baseline FVIII/IX levels 0.02 to 0.05 IU/mL to >0.25 IU/mL, the median ABR decreased from 0.6 (IQR, 0.2-1.4) to 0.1 (IQR, 0.0-0.2) and the AJBR from 0.2 (IQR, 0.0-0.4) to 0.0 (IQR, 0.0-0.0). Baseline FVIII/IX was inversely associated with the joint bleeding rate (P < .001). Low bleeding rates were observed in persons with nonsevere hemophilia. However, one-half of all adolescents and adults had experienced a joint bleed.

The long-term clinical benefits and economic costs associated with increased use of prophylaxis among patients with haemophilia A in China: Population-based predictions from 2018 to 2033. Haemophilia 2022; 28:726-736. [PMID: 35714660 DOI: 10.1111/hae.14603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 04/22/2022] [Accepted: 05/24/2022] [Indexed: 11/28/2022]
Abstract
AIM To predict the long-term benefits and economic costs of the improvements in haemophilia care in China demonstrated by increasing use of prophylaxis, compared with the current status. METHODS City-level predictions from 2018 to 2033 were conducted for five representative cities in China. The long-term clinical and economic outcomes in the scenario where haemophilia care has significantly improved and the existing scenario of haemophilia care were calculated and compared. The model input data were obtained from local records, expert interviews, published literature, and other sources. Outcome measures including number of bleeds and joint bleeds, number of target joints, disability rate, direct and indirect costs were calculated at the patient and population levels. RESULTS The long-term predictions for 2033 demonstrated significantly improved bleed control and joint outcomes due to increased use of prophylaxis. The total number of averted bleed events per patient ranged from 3.9 in Shenyang to 16.1 in Zhengzhou in 2033, and the population-level averted bleed events ranged from 1963 in Xiamen to 14,868 in Zhengzhou. The treatment improvement also leads to significant economic costs driven by increase in clotting factor costs (more than 90%). At the population level, the additional total costs were highest in Zhengzhou (CNY 177.4 million) and lowest in Shenyang (CNY 45.4 million), due to their different population sizes and various existing treatment regimens. The outpatient and hospitalization costs decreased, while the factor costs increased. CONCLUSION The long-term prophylaxis is associated with avoided bleed events and disabilities. The improved treatment regimens are also associated with a significant economic burden, driven by factor costs.

Abstract
INTRODUCTION Economic evaluations typically focus solely on patient-specific costs with economic spillovers to informal caregivers less frequently evaluated. This may systematically underestimate the burden resulting from disease. AREAS COVERED Cost-of-illness (COI) analyses that identified costs borne to caregiver(s) were identified using PubMed and Embase. We extracted study characteristics, clinical condition, costs, and cost methods. To compare caregiver costs reported across studies, estimated a single 'annual caregiver cost' amount in 2021 USD. EXPERT OPINION A total of 51 studies met our search criteria for inclusion with estimates ranging from $30 - $86,543. The majority (63%, 32/51) of studies estimated caregiver time costs with fewer studies reporting productivity or other types of costs. Caregiver costs were frequently reported descriptively (69%, 35/51), with fewer studies reporting more rigorous methods of estimating costs. Only 27% (14/51) of studies included used an incremental analysis approach for caregiver costs. In a subgroup analysis of dementia-focused studies (n = 16), we found the average annual cost of caregiving time for patients with dementia was $30,562, ranging from $4,914 to $86,543. We identified a wide range in annual caregiver cost estimates, even when limiting by condition and cost type.

Abstract
Hemophilia A is characterized by unpredictable spontaneous bleeds and chronic comorbidities. However, limited data exists at the national level into detailed management patterns related to patient clinical characteristics, representative real-world dosing and treatment frequency, and costs. To assess and characterize the US severe hemophilia A (SHA) population, including subgroups of patients, in terms of clinical and demographic characteristics, healthcare resource utilization received at hemophilia treatment centers (HTCs), and projected annual costs of treatment utilizing data from the ATHNdataset of the American Thrombosis and Hemostasis Network (ATHN). Adult male people with SHA (PwSHA) (FVIII < 1%) were identified in the ATHNdataset between January 2013 and September 2019. This retrospective cohort study described patients' demographic and clinical characteristics, clinical history, as well as the HTC-related health resource utilization (HRU), treatment utilization, and projected annual treatment costs of US PwSHA received over the most recent year. Results are reported for the overall population and for three mutually exclusive subpopulations of patients: PwSHA with a history of and/or current inhibitors, PwSHA without a history of inhibitors but with (or a history of) one or more transfusion-transmitted infections (hepatitis B virus [HBV], hepatitis C virus [HCV], or human immunodeficiency virus [HIV]), and PwSHA without a history of inhibitors or of transfusion-transmitted infections (HBV, HCV, or HIV). Of the overall PwSHA cohort (N = 3677), there was a high prevalence of HCV (24.1%) and HIV (13.7%), while the prevalence of HBV (4.9%) was lower. Note that 20.5% of PwSHA overall currently or ever had FVIII inhibitors. On average, PwSHA had 2.8 total HTC visits per year, including 0.9 comprehensive care visits, 1.1 telephone contact visits, 0.5 office visits, and 0.1 surgeries or other procedures. However, 23.3% of PwSHA were not seen at an HTC, and 33.8% of PwSHA did not have a comprehensive care visit during their most recent year of data. HTC-related HRU was similar between the overall cohort and across the patient subpopulations, although PwSHA and inhibitors had more frequent HTC visits (a mean of 3.6 visits annually vs. 2.5-2.8 in the other groups). Using reported treatment frequency and dosing, estimated mean annual hemophilia treatment costs varied by treatment and across the three subpopulations: extended half-life factor product ($893,609-934,301 by subpopulation), standard half-life factor product ($798,700-930,812), plasma-derived factor product ($613,220-801,061), and non-factor product treatment ($765,289-833,240). This study summarized recent sociodemographic and clinical characteristics, HTC-related HRU, and HA treatments and projected costs among adult PwSHA, including among key subpopulations of PwSHA. PwSHA experience substantial clinical and resource burden on a chronic basis, despite the care coordination efforts of ATHN-affiliated HTCs. These findings motivate further exploration of the drivers of resource utilization, observed differences across subpopulations and other disparities, and ongoing monitoring of clinical and treatment burden in the face of an evolving care landscape.

Abstract
Purpose We compare the impact of hemophilia on comorbidities, joint problems, health-related quality of life (HRQoL) and health-care utilization between two age groups: 40–49 years and ≥50 years. Patients and Methods The HUGS VII study recruited persons with hemophilia A or B age ≥40 years. Participants completed surveys to collect data on sociodemographic and clinical characteristics, hemophilia treatment regimen, pain, joint problems, comorbidities, HRQoL, depression and anxiety, at baseline and 6-months later. Clinical chart reviews documented hemophilic severity and treatment. Results The sample includes 69 males, 65.2% aged ≥50 years, 75.4% with hemophilia A. Individuals ≥50 years were more likely to have mild or moderate hemophilia (68.9% vs 41.7%, P = 0.03) than those 40–49 years old. Among persons with mild/moderate hemophilia, those ≥50 years old reported a higher rate of joint pain (83.9% vs 70.0%, P = 0.34 at baseline, 91.3% vs 57.1%, P = 0.06 at follow up) or range of motion limitation (73.3% vs 60.0%, P = 0.43 at baseline, 73.9% vs 28.6%, P = 0.04 at follow up) than the younger group. Compared to the younger group, the older group reported fewer emergency room visits (4.5% vs 21.7%, P = 0.03), and physical therapy visits (15.9% vs 43.5%, P = 0.01) at baseline. The sample depression rate was 85.7%, but the differences among the age groups were not significant. The mean covariate-adjusted EQ-5D index score was lower in older persons (0.77 vs 0.89, P = 0.02). Conclusion Older persons with hemophilia in this sample are over-represented by individuals with mild/moderate disease, potentially due to premature death among those with severe disease. Although this group included a larger proportion of individuals with mild disease than the younger group, they experienced lower quality of life, more comorbidities both of aging and of hemophilic arthropathy, and lower rates of health-care utilization.

Abstract
Background Nephrotic syndrome (NS) is a rare kidney syndrome with high morbidity. Although a common contributor to the burden of chronic kidney disease, the direct and indirect costs of NS to patients and family caregivers are unrecognized. The objective was to characterize the direct and indirect costs of NS to patients. Methods Adults with NS and family caregivers of children with NS were eligible to participate if they had a diagnosis of primary NS, had disease for at least 1 year, and had no other severe health conditions. Data-collection surveys were generated with input from the Kidney Research Network Patient Advisory Board, and surveys were mailed to the eligible participants. Participants were provided $50 for the return of completed surveys. Costs were defined as either direct out-of-pocket costs or indirect costs (e.g., time). Descriptive statistics, including percentage and median (interquartile range [IQR]) are reported. Results Respondents included 28 adult patients and 17 caregivers of patients who were minors. Reported health insurance coverage included 35 (78%) with private insurance, 12 (27%) with public insurance, six (13%) with Children's Special Health Care Services, and one (2%) uninsured. Median annual direct costs were $3464 ($844-$5865) for adult patients and $1687 (IQR $1035-$4763) for caregivers. Of these costs, diet-associated costs contributed $1140 (IQR $600-$2400). The most substantial indirect cost was from the time spent planning/prepping meals (adults: 183 h/yr [IQR 114-331]; caregivers: 173 h/yr [IQR 84-205]). Conclusions Adults and caregivers of children with NS face substantial disease-related direct and indirect costs beyond those covered by insurance. Following replication, the study will help health care providers, systems, and payers gain a better understanding of the financial and time burden incurred by those living with NS, consider barriers when treating patients, and develop supportive strategies.

Abstract
Background Hemophilia care in mainland China has been greatly improved since the establishment of the Hemophilia Treatment Center Collaborative Network of China (HTCCNC), and most of drugs for hemophilia have been covered by basic medical insurance schemes. This study assesses whether medical costs and hospital utilization disparities exist between hemophilia A and hemophilia B urban inpatients in China and, second, whether the prescription of coagulation factor concentrates for hemophilia A and hemophilia B inpatients was optimal, from the third payer perspective. Methods We conducted a retrospective nationwide analysis based on a 5% random sample from claims data of China Urban Employees’ Basic Medical Insurance (UEBMI) and Urban Residents’ Basic Medical Insurance (URBMI) schemes from 2010 to 2016. Univariate analysis and multiple regression analysis based on a generalized linear model were conducted. Result A total of 487 urban inpatients who had hemophilia were identified, including 407 inpatients with hemophilia A and 80 inpatients with hemophilia B. Total medical cost for hemophilia B inpatients was significantly higher than for hemophilia A inpatients (USD 2912.81 versus USD 1225.60, P < 0.05), and hemophilia B inpatients had a significantly longer length of hospital stay than hemophilia A inpatients (9.00 versus 7.00, P < 0.05). Total medical costs were mostly allocated to coagulation factor products (76.86-86.68%), with coagulation factor cost of hemophilia B significantly higher than hemophilia A (P < 0.05). Both hemophilia cohorts utilized greatest amount of plasma-derived Factor VIII, followed by recombinant Factor VIII and prothrombin complex concentrates. Conclusions Patients with hemophilia B experienced significantly higher inpatient cost, coagulation factor cost and longer length of hospital stay than patients with hemophilia A. Our findings revealed the suboptimal use of coagulation factor concentrate drugs and a higher drug cost burden incurred by hemophilia B than hemophilia A inpatients. Our results call for efforts to strengthen drug regulatory management for hemophilia and to optimize medical insurance schemes according to hemophilia types.

Abstract
OBJECTIVE The Hemraude study was conducted to describe the profile of patients with HA, disease management, and economic burden in a collective perspective. METHODS This retrospective study was conducted using the French administrative healthcare claims database SNIIRAM/SNDS. Male patients treated for hemophilia A with a long-term illness (ALD) status or invalidity were included in the study between January 1, 2016 and December 31, 2017. Patients were classified in six treatment groups: no treatment, on-demand FVIII, prophylactic FVIII, FVIII in immune tolerance induction (ITI) protocol, on-demand bypassing agents, and prophylactic bypassing agents. Patients treated with FVIII in ITI protocol and those treated with bypassing agents are deemed to have developed inhibitors. HA patients were compared to a control population without coagulation disorder and matched (ratio 1:3) on age and sex. RESULTS A total of 4172 patients were included in the analysis, aged on average 35.2 years, 5.3% had HIV infection, and 8.8% had hepatitis B or C. In 2017, half of the patients received no treatment for HA, 46.7% were treated with FVIII (25% on demand, 20.6% with prophylaxis, and 1.1% ITI), 1.5% with bypassing agents. Patients treated with prophylactic treatments, either inhibitor or non-inhibitor, were less likely to be hospitalized for severe bleeding compared to patients receiving on-demand treatments. The average annual costs for HA management per patient were 72,209.60 €. The highest costs were observed in patients treated with FVIII in ITI protocol and those receiving prophylactic bypassing agents. CONCLUSION Direct costs of HA treatments for HA may be very high especially in the small percentage of patients developing inhibitors or treated with ITI protocol.

Current and Emerging Approaches for Pain Management in Hemophilic Arthropathy. Pain Ther 2022; 11:1-15. [PMID: 35020184 PMCID: PMC8861243 DOI: 10.1007/s40122-021-00345-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Accepted: 12/07/2021] [Indexed: 12/26/2022] Open
Abstract
Introduction Hemophilia is an inherited bleeding hematological disorder characterized by the partial or complete deficiency of clotting factor VIII or IX. Hemophilic arthropathy is the consequence of repeated joint bleeding (hemarthrosis) and its management is based on the prevention of acute bleeding through the administration of the deficient clotting factor concentrate or non-factor therapies. In addition, the management of acute and chronic pain is pivotal in hemophilic arthropathy in order to restore function and allow rehabilitation of the joint.
Methods We conducted a qualitative review of the literature regarding current and emerging strategies for pain treatment in hemophilic arthropathy. This review considers systemic and local pharmacological and non-pharmacological interventions for acute and chronic pain management.
Results In hemophilic arthropathy, pain management is based on analgesics such as paracetamol, which represents the first choice for acute and chronic pain in adults and children, in association with opioids for adults. Non-steroidal anti-inflammatory drugs inhibit platelet function, so that the currently preferred drugs are short courses of cyclooxygenase 2 inhibitors. Local treatment with intra-articular injections of corticosteroids is an option for refractory cases and physiotherapy has an important role after hemarthrosis and for the long-term management of chronic pain for both pediatric and adult patients.
Conclusions The management of pain in hemophilia requires more standardization. Meanwhile, the safest drugs should be used at the lowest effective dosage and for periods as short as possible. For the non-pharmacological management of pain in these patients, a multidisciplinary team including hematologists, orthopedic surgeons, rheumatologists, and physiotherapists is warranted.

Abstract
AIMS To assess real-world use of emicizumab in adult people with hemophilia A (PwHA) without inhibitors including healthcare resource utilization (HCRU) and costs. MATERIALS AND METHODS Adult, male PwHA without inhibitors initiating emicizumab (index date) were identified using IBM MarketScan after 4 October 2016. Patients were required to have continuous health insurance coverage for ≥180 days prior to and ≥90 days after index date and have ≥90 days of continuous use of emicizumab. Patients were followed until treatment gap, disenrollment, or end of data. Results were reported overall and among a subgroup with prior factor VIII (FVIII) prophylaxis. Emicizumab use, concomitant FVIII treatment use, HCRU, and costs were assessed separately over baseline, the emicizumab induction period, emicizumab maintenance period, and annualized. RESULTS Among the 71 emicizumab patients (FVIII prophylaxis subgroup: 52) included in the study, the mean age was 35 (subgroup: 34) years and mean follow-up was 12 (subgroup: 11.1) months. At baseline, the annualized mean total healthcare cost was $532,948 (subgroup: $645,727). After emicizumab initiation, per-patient-per-month (PPPM) HCRU was higher in the emicizumab induction period compared to the maintenance period with higher monthly FVIII fills/in-office administrations (0.37 vs 0.17), non-FVIII outpatient visits (2.23 vs 1.55), and emergency department visits (0.06 vs 0.03). The FVIII prophylaxis subgroup yielded similar HCRU trends. Hemophilia treatment costs accounted for over 95% of total healthcare costs. The annualized mean cost was $50,491 (subgroup: $61,512) for concomitant FVIII treatment and $777,171 (subgroup: $793,168) for emicizumab and concomitant FVIII treatment for the first year of emicizumab treatment. CONCLUSION This study represented experience with emicizumab after the approval for PwHA without inhibitors. The study cohort may not be representative of all PwHA taking emicizumab. The findings highlight the continued burden of treatment and healthcare cost for PwHA without inhibitors despite advances in treatment options.

Abstract
OBJECTIVE The aim of this post-hoc analysis was to assess the impact of lurasidone monotherapy on functional impairment, productivity, and associated indirect costs in patients with bipolar depression. METHODS Data were analyzed from a 6-week randomized, double-blind (DB; NCT00868699), placebo-controlled trial of lurasidone monotherapy and a 6-month open label extension (OLE; NCT00868959) study. Patients with bipolar depression who completed the 6-week DB trial were subsequently enrolled in the OLE. Analysis of the OLE was limited to patients who either continued lurasidone (LUR-LUR) or switched from placebo to lurasidone monotherapy (PBO-LUR). The Sheehan Disability Scale (SDS), which measures functional impairment and productivity, was collected at DB baseline, DB week 6/OLE baseline, OLE month 3, and OLE month 6. Annual indirect costs were calculated based on days lost or unproductive from work/school due to symptoms. Effect sizes (ES) in functioning and days lost/unproductive were reported for the DB trial and mean changes for the OLE. RESULTS A total of 485 patients were enrolled in the DB trial (lurasidone: n = 323; placebo: n = 162) and 316 were in the lurasidone monotherapy group during the OLE (LUR-LUR: n = 210; PBO-LUR: n = 106). In the DB trial, improvements in functioning (work: ES = 0.36, p = .0071; social: ES = 0.55, p < .0001; family: ES = 0.50, p < .0001) were significantly greater for lurasidone compared to placebo. Reductions in days lost (ES = 0.33, p = .0050) and unproductive (ES = 0.45, p = .0001) were significantly higher for lurasidone vs. placebo. This resulted in a greater reduction in indirect costs for lurasidone vs. placebo (least squares mean (standard error) = -$32,322 ($2,100) vs. -$20,091 ($2,838)). Improvements in functioning and productivity were sustained during the 6-month OLE for both LUR-LUR and PBO-LUR. CONCLUSIONS Lurasidone monotherapy for the treatment of bipolar depression significantly improved functioning and reduced indirect costs vs. placebo at week 6. Significant improvements in functioning and productivity were sustained for 6 months for both LUR-LUR and PBO-LUR.

Abstract
BACKGROUND: Standard of care for patients with severe hemophilia A (HA) is life-long prophylaxis with factor VIII (FVIII) concentrate or other hemostatic agents. Published literature highlights a wide range of treatment costs for patients with HA. OBJECTIVE: To estimate average annual health care costs and resource utilization for a cross-section of adult patients managed with FVIII concentrate prophylaxis using recent data from a large US commercial claims database. METHODS: Adult males with 1 or more claim with HA diagnosis, continuous commercial plan enrollment, and 4 or more FVIII prescription dispenses during 12 months were identified from IBM MarketScan Research Database from January 2013 to September 2019, excluding those with FVIII inhibitors, an HIV/AIDS diagnosis, or diagnosis and treatment for hepatitis B or C. Patients were classified as using FVIII prophylaxis if they met any of the following definitions: (1) 6 or more FVIII dispenses, (2) a gap of 60 days or less between dispenses, and (3) at least 273 days supply in the 12-month period. Additionally, subgroups of patients meeting each individual definition were examined, with some patients included in all 3 subgroups. RESULTS: The overall cohort included 411 patients who met 1 or more of the 3 definitions, with a mean age of 28.9 years. Subgroups of 401, 325, and 237 patients met the first, second, and third FVIII prophylaxis definitions, respectively. Per-patient mean (SD) annual all-cause health care costs were $654,571 ($380,762) in the overall cohort and ranged from $650,065 ($382,196) to $759,661 ($387,040) among subgroups. Cost of FVIII concentrate accounted for more than 96% of total costs in the overall cohort and in each subgroup. Cost of FVIII in the overall cohort varied according to type of concentrate, with the highest among patients who were treated with both standard and extended half-life (SHL and EHL) FVIII ($784,945), followed by EHL FVIII only ($708,928), SHL FVIII only ($647,800), and plasma-derived FVIII ($535,614). The most common treatment type was SHL FVIII only (45.7% of all patients). In the overall cohort, the majority had 1 or more outpatient visits (94.9%), while emergency department visits, hospital admissions, and home health visits occurred less frequently (27.0%, 7.1%, and 7.1%, respectively). CONCLUSIONS: Commercially insured patients with HA incur substantial all-cause annual health care costs, with FVIII concentrate accounting for a majority of costs.

Abstract
BACKGROUND: Hemophilia A (HA) is marked by substantial economic burden, including costs of ongoing treatment, increased monitoring, bleed events, and other health care utilization associated with managing the disease and comorbidities related to the disease. Gene therapies and other anticipated breakthrough treatments hold potential to substantially offset long-term traditional factor VIII (FVIII) prophylaxis in specific populations. Fragmentation of the US insurance system, however, may impact payers' approaches to coverage of new treatments, given concerns about patients "switching" insurance and the payer's ability to offset costs over time. OBJECTIVE: To assess insurance coverage and switching across payers among people with severe HA (SHA) using real-world data. METHODS: Adult men with SHA (FVIII measuring < 1%) in the American Thrombosis and Hemostasis Network dataset between January 2013 and September 2019 were identified. Patients' primary insurance category (ie, commercial, Medicaid, Medicare) and insurance switching over time were described. Outcomes included distribution of current primary insurance coverage by category and mean years of coverage per payer for commercially insured patients, including those with 2 or more commercial payers, and for those who switched insurance categories (eg, coverage by a commercial payer and government payer). RESULTS: Among the cohort of patients with SHA (N = 3,677), 51.9% had commercial primary insurance and 29.0% had coverage by Medicaid (including state-funded programs). The mean duration of follow-up in the database was 6.3 years for patients with at least 1 year of follow-up. Among patients who had ever been commercially insured, 74.9% had the same commercial payer for the entire follow-up period. The mean time covered by the same commercial insurance was 4.8 years. Only 7.5% of patients switched insurance categories (eg, from commercial to Medicaid). Among those who switched categories, patients averaged 3.9 years of commercial coverage, 4.0 years of Medicaid coverage, and 4.8 years of Medicare coverage during the follow-up period. CONCLUSIONS: Both commercially and government-insured patients with SHA typically maintain continuous coverage for extended periods, with limited switching between payers and insurance categories over time. These findings suggest that should breakthrough treatments be approved, payers would likely be able to realize substantial cost savings associated with avoiding long-term prophylactic therapies during the several years after treatment.

Abstract
The safety and efficacy of several life-saving therapeutic proteins are compromised due to their immunogenicity. Once a sustained immune response against a protein-based therapy is established, clinical options that are safe and cost-effective become limited. Prevention of immunogenicity of therapeutic proteins prior to their initial use is critical as it is often difficult to reverse an established immune response. Here, we discuss a rational design and testing of a phosphatidylserine-containing nanoparticle platform for novel oral prophylactic reverse vaccination approach, i.e., pre-treatment of a therapeutic protein in the presence of nanoparticles to prevent immunogenicity of protein therapies.

Abstract
BACKGROUND Dosing of replacement therapy with factor VIII concentrate in patients with haemophilia A in the perioperative setting is challenging. Underdosing and overdosing of factor VIII concentrate should be avoided to minimise risk of perioperative bleeding and treatment costs. We hypothesised that dosing of factor VIII concentrate on the basis of a patient's pharmacokinetic profile instead of bodyweight, which is standard treatment, would reduce factor VIII consumption and improve the accuracy of attained factor VIII levels. METHODS In this open-label, multicentre, randomised, controlled trial (OPTI-CLOT), patients were recruited from nine centres in Rotterdam, Groningen, Utrecht, Nijmegen, The Hague, Leiden, Amsterdam, Eindhoven, and Maastricht in The Netherlands. Eligible patients were aged 12 years or older with severe or moderate haemophilia A (severe haemophilia was defined as factor VIII concentrations of <0·01 IU/mL, and moderate haemophilia as 0·01-0·05 IU/mL), without factor VIII inhibitors, and planned for elective low or medium risk surgery as defined by surgical risk score. Patients were randomly assigned (1:1) using a web-based randomisation system and treatment minimisation, stratified by method of administration of factor VIII concentrate (continuous infusion vs bolus administration) and risk level of surgery (low and medium risk surgery), to the pharmacokinetic-guided or standard treatment group. The primary endpoint was total amount of infused factor VIII concentrate (IU per kg bodyweight) during perioperative period (from day of surgery up to 14 days after surgery). Analysis was by intention to treat and the safety analysis population comprised all participants who underwent surgery with factor VIII concentrate. This study is registered with the Netherlands Trial Registry, NL3955, and is now closed to accrual. FINDINGS Between May 1, 2014, and March 1, 2020, 98 patients were assessed for eligibility and 66 were enrolled in the trial and randomly assigned to the pharmacokinetic-guided treatment group (34 [52%]) or the standard treatment group (32 [48%]). Median age was 49·1 years (IQR 35·0 to 62·1) and all participants were male. No difference was seen in consumption of factor VIII concentrate during the perioperative period between groups (mean consumption of 365 IU/kg [SD 202] in pharmacokinetic-guided treatment group vs 379 IU/kg [202] in standard treatment group; adjusted difference -6 IU/kg [95% CI -88 to 100]). Postoperative bleeding occurred in six (18%) of 34 patients in the pharmacokinetic-guided treatment group and three (9%) of 32 in the standard treatment group. One grade 4 postoperative bleeding event occurred, which was in one (3%) patient in the standard treatment group. No treatment-related deaths occurred. INTERPRETATION Although perioperative pharmacokinetic-guided dosing is safe, it leads to similar perioperative factor VIII consumption when compared with standard treatment. However, pharmacokinetic-guided dosing showed an improvement in obtaining factor VIII concentrations within the desired perioperative factor VIII range. These findings provide support to further investigation of pharmacokinetic-guided dosing in perioperative haemophilia care. FUNDING Dutch Research Council (NWO)-ZonMw and Takeda.

Abstract
OBJECTIVE Given that the mechanism for financial protection is underdeveloped in Nigeria, out-of-pocket (OOP) payment for treating cardiovascular disease could impose substantial financial burden on individuals and their families. This study estimated the burden of OOP expenditures incurred by a cohort of patients with cardiovascular disease (CVD) in Ibadan, Nigeria. DESIGN AND SETTINGS This study used a descriptive cross-sectional study design. A standardised survey questionnaire originally developed by Initiative for Cardiovascular Health Research in Developing Countries was used to electronically collect data from all the 744 patients with CVD who accessed healthcare between 4 November 2019 and 31 January 2020 in the cardiology departments of private and public hospitals in Ibadan, Nigeria. Baseline characteristics of respondents were presented using percentages and proportions. The OOP payments were reported as means±SDs. Costs/OOP payments were in Nigerian Naira (NGN). The average US dollar to NGN at the time of data collection was ₦362.12 per $1. All quantitative data were analysed using STATA V.15. OUTCOME MEASURES The burden of outpatient, inpatient and rehabilitative care OOP payments. RESULTS Majority of the patients with CVD were within the age range of 45-74 years and 68.55% of them were women. The diagnostic conditions reported among patients with CVD were hypertensive heart failure (84.01%), dilated cardiomyopathy (4.44%), ischaemic heart disease (3.9%) and anaemic heart failure (2.15%). Across all the hospital facilities, the annual direct and indirect outpatient costs were ₦421 595.7±₦855 962.0 ($1164.2±$2363.8) and ₦19 146.5±₦53 610.1 ($52.87±$148.05). Similarly, the average direct and indirect OOP payments per hospitalisation across all facilities were ₦182 302.4±₦249 090.4 ($503.43±$687.87) and ₦14 700.8±₦ 69 297.1 ($40.60±$191.37), respectively. The average rehabilitative cost after discharge from index hospitalisation was ₦30 012.0 ($82.88). CONCLUSION The burden of OOP payment among patients with CVD is enormous. There is a need to increase efforts to achieve universal health coverage in Nigeria.

Optimizing language for effective communication of gene therapy concepts with hemophilia patients: a qualitative study. Orphanet J Rare Dis 2021; 16:189. [PMID: 33910590 PMCID: PMC8082836 DOI: 10.1186/s13023-020-01555-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Accepted: 09/23/2020] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND For communities of people living with hemophilia and other genetic conditions, gene therapy could represent a paradigm shift in treatment strategies. As investigational therapeutic modalities such as gene therapy become more widely used and discussed, there is a critical need for all stakeholders to communicate using a lexicon that is intelligible, accurate, consistent, and representative of novel treatments. In doing so, expectations can be more carefully managed and potential risks, benefits, and limitations better understood. In recognition of this need, a first-ever study of gene therapy lexicon was conducted using established methods of market research and linguistic analysis. METHODS Ninety-four participants representing hematologists, nurses, caregivers, and people with hemophilia A, in six countries (US, UK, Spain, Germany, France, Italy) took part in a series of in-depth interviews, face-to-face focus groups, an advisory board meeting, and online group interviews to develop, refine, and test verbal, written, and pictorial language concepts through a three-phase iterative process. Sessions were conducted in local languages using detailed discussion guides. Feedback from participants was captured using real-time instant-response dial testing to measure moment-by-moment emotional responses to language stimuli. Semiquantitative analysis of the responses informed selection of preferred language concepts for final testing, and qualitative discussion explored preference rationale. Participants also completed polling and forced rank and choice written exercises. RESULTS Study feedback showed that the hemophilia community has preferences around consistent lexicon to describe hemophilia and its management. Expert linguistic analysis of feedback from the three phases enabled agreement of a consensus lexicon of vocabulary and an optimized summary narrative for talking about gene therapy amongst people affected by hemophilia A. Preferences were largely consistent across audiences and countries, although some country-specific recommendations were made. A representative summary phrase was agreed: "Gene therapy is being studied in clinical trials with the aim to allow the body to produce factor VIII protein on its own". CONCLUSIONS The use of preferred language across different stakeholders increases understanding and comfort during discussions of novel and complex therapeutic modalities such as gene therapy. Consistent use of community-informed lexicon minimizes miscommunication and facilitates informed decision-making regarding potential future treatment opportunities.

Abstract
Background: Within the EU, some of the challenges and perceived risks now facing medical device (MD) developers result from changes in the regulatory framework, emphasizing safety. Therefore, medical technology companies must adopt stricter quality assurance measures so that individual devices can be speedily tracked and retrieved in emergency situations. Objectives: We highlight the challenges and risks faced by the European medical devices industry, particularly those faced by SMEs in the Czech Republic. We address two important research questions: Q1. Do advantages from increased regulation outweigh the additional expenses? Q2. As many MD developers are SMEs, will the new regulatory regime result in some of those companies going out of business and therefore impede future innovation? Methods: The paper focuses on a single case study, with the situation and outcomes discussed in the context of the financial results of a further 50 medical device manufacturers marketing in the Czech Republic. Results: Our findings suggest that the new legislation will result in improved safety, facilitate product recalls, but the cost and administrative burden may be high. The evidence also indicates that some SMEs may be forced to diversify to “non-medical” products, with the inevitable loss of innovative MDs being made available to patients and healthcare providers.

Abstract
Objective The aim of this scoping review was to overview the cost-of-illness studies conducted in rare diseases.
Methods We searched papers published in English in PubMed from January 2007 to December 2018. We selected cost-of-illness studies on rare diseases defined as those with prevalence lower than 5 per 10,000 cases. Studies were selected by one researcher and verified by a second researcher. Methodological characteristics were extracted to develop a narrative synthesis.
Results We included 63 cost-of-illness studies on 42 rare diseases conducted in 25 countries, and 9 systematic reviews. Most studies (94%) adopted a prevalence-based estimation, where the predominant design was cross-sectional with a bottom-up approach. Only four studies adopted an incidence-based estimation. Most studies used questionnaires to patients or caregivers to collect resource utilisation data (67%) although an important number of studies used databases or registries as a source of data (48%). Costs of lost productivity, non-medical costs and informal care costs were included in 68%, 60% and 43% of studies, respectively. Conclusion This review found a paucity of cost-of-illness studies in rare diseases. However, the analysis shows that the cost-of-illness studies of rare diseases are feasible, although the main issue is the lack of primary and/or aggregated data that often prevents a reliable estimation of the economic burden.

Health care resource utilization and costs among adult patients with hemophilia A on factor VIII prophylaxis: an administrative claims analysis. J Manag Care Spec Pharm 2021; 27:316-326. [PMID: 33645244 PMCID: PMC10391018 DOI: 10.18553/jmcp.2021.27.3.316] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/05/2022]
Abstract
BACKGROUND: Standard of care for bleed prevention in patients with severe congenital hemophilia A is continuous prophylaxis with factor VIII (FVIII), typically administered intravenously 2-3 times per week in the home setting. Nonfactor prophylaxis and gene therapy are emerging novel prophylaxis strategies for hemophilia A, and it is important to compare their health economics with that of FVIII prophylaxis. Current data on resource utilization and costs in the adult hemophilia A prophylaxis population are limited, and a structured approach to analyze annual costs in these patients using administrative claims data has not been previously reported. OBJECTIVE: To assess health care resource utilization and costs of continuous FVIII prophylaxis in commercially insured adults with hemophilia A without inhibitors. METHODS: Administrative claims records from beneficiaries covered by major selfinsured companies in the United States from January 1999 through March 2017 (OptumHealth Care Solutions) were queried, and records for adult patients (aged 18-64 years) diagnosed with hemophilia A who received FVIII were extracted. Three criteria were defined to distinguish patients most likely to be managed with continuous FVIII prophylaxis from those on episodic treatment based on the frequency and timing of FVIII claims over a 12-month period of continuous enrollment: (1) having ≥ 4 FVIII claims, (2) having ≥ 6 FVIII claims, or (3) having no gaps > 60 days between FVIII claims. Patients with evidence of bypassing agent use were excluded. Health care resource utilization and costs were assessed for all patients with any FVIII use and for patients defined as being managed with continuous FVIII prophylaxis based on each criterion. RESULTS: The analysis included 189 patients with a diagnosis code for hemophilia A (ICD 9-CM code 286.0; ICD-10-CM code D66) from January 1999 through March 2017 who had at least 12 months of continuous enrollment and at least 1 noninpatient/nonemergency department claim for FVIII concentrate (any type) during their last 12 months of continuous enrollment (overall cohort). Within the overall cohort, 118, 94, and 61 patients met the criteria for FVIII prophylaxis based on the first, second, and third definitions, respectively. Per patient mean (SD) total health care costs for the overall cohort was $287,055 (306,933). For patients meeting criteria 1 through 3, per patient costs ranged from $407,752 (321,036) to $551,645 (302,841). FVIII concentrate accounted for over 90% of costs, with mean (SD) annual FVIII costs of $264,777 (292,423) in the overall cohort and $384,197 (303,826), $433,029 (313,711), and $531,098 (297,142) among patients meeting the respective definitions for prophylaxis. CONCLUSIONS: This analysis highlights the substantial economic burden associated with managing adults with hemophilia A on FVIII prophylaxis, where per patient mean total annual health care costs ranged from $407,752 to $551,645. Over 90% of such costs were attributable to FVIII concentrate dispensed.

Abstract
BACKGROUND US commercial health plans have been found to vary in how they cover specialty drugs indicated for a range of diseases. In this study, we examined patients' access to hemophilia A (HemA) treatments across a set of large commercial health plans. OBJECTIVE To examine variation in health plans' coverage policies for HemA treatments. METHODS We reviewed HemA treatment coverage policies (current as of August 2019) issued by 17 commercial health plans primarily using the Tufts Medical Center Specialty Drug Evidence and Coverage Database. We categorized policies as: covered without conditions (coverage consistent with the FDA label); covered with conditions (conditions on coverage beyond the FDA label); broader coverage (coverage for a broader patient population than the FDA label); and mixed (conditions on coverage beyond the FDA label in one way, but coverage was broader than the FDA label in another). RESULTS We identified 296 coverage policies for 26 HemA treatments, including 15 short half-life factor VIII (FVIII) products, five extended half-life FVIII products, three bypassing agents, two desmopressin products, and emicizumab. We classified 36% of policies as coverage without conditions, 50% as covered with conditions, 7% as broader coverage, and 7% as mixed. Plans applied conditions on coverage with different frequencies: two did not apply conditions in any policies; ten applied conditions in ≥50%; four applied conditions in <40%. One plan did not publish coverage policies for any HemA products. Conditions on coverage most often related to bleeding frequency (36%), although specific requirements varied. Plans applied step therapy protocols in 17% of policies. CONCLUSIONS How health plans covered HemA treatments varied. Plans added conditions on coverage beyond the FDA label roughly half the time. Conditions most often related to bleeding frequency. Variable coverage affects patients' access to treatment, and potentially has clinical implications on disease management and disease progression.

Abstract
INTRODUCTION Characterisation of outcomes and costs of haemophilia care in common practice settings is essential for evaluation of new treatment options and for developing clinical practices. In Finland, haemophilia care is mostly centralised to University Hospitals, but treatment practices and costs in adult patients have not been systematically evaluated. AIM This study was designed to characterise healthcare resource utilisation and treatment costs of adult inhibitor-negative haemophilia patients managed in Finnish University Hospitals. METHODS The study was based on a nationwide cohort, which consists of all adult haemophilia A (HA; n = 120) and B (HB; n = 35) patients treated in University Hospitals from 2012 to 2016. Patient characteristics and data on healthcare utilisation and factor replacement use were collected from medical records. Direct costs of care were evaluated based on wholesale drug prices and healthcare service utilisation with standard unit costs. RESULTS Most of HA (79%, n = 96) and HB (84%, n = 31) patients received factor replacement therapy. The median annual bleeding rate (ABR) was low, at 0.8 for HA and 0.5 for HB, also among the patients with on-demand therapy. Over 94% (n = 149) of the patients had outpatient visits during the follow-up period. The mean total annual costs of treatment ranged from €2520 to €176,330. The highest individual cost was factor replacement therapy. CONCLUSION The outcomes of centralising the management of care to University Hospital Treatment Centres show low ABR and lower treatment costs compared with earlier reports from other high-income European populations. Management strategies, including choosing the right therapy between prophylaxis and on-demand, has been successful in Finland.

Abstract
: Standard-of-care treatment for haemophilia A or B is to maintain adequate coagulation factor levels through clotting factor administration. The current study aimed to evaluate annualised bleeding rates (ABR) and treatment adherence for haemophilia A or B patients receiving standard half-life (SHL) vs. extended half-life (EHL) factor replacement products. We analysed data from the Adelphi Disease-Specific Programmes, a health record-based survey of United States and European haematologists. Analysis included 651 males with moderate-to-severe haemophilia A or B (the United States, n = 132; Europe, n = 519). The haemophilia A analysis included 501 patients (SHL, n = 435; EHL, n = 66). In the combined United States/European population, mean (SD) ABR was 1.7 (1.69) for the SHL group and 1.8 (2.00) for the EHL group. A total of 72% of patients receiving SHL factor VIII and 75% of patients receiving EHL factor VIII in the combined population were fully adherent (no doses missed of the last 10 doses), as reported by physicians. The haemophilia B analysis included 150 patients (SHL, n = 114; EHL, n = 36). The mean (SD) ABR in the combined population was 2.1 (2.16) for patients receiving SHL factor IX (FIX) and 1.4 (1.48) for patients receiving EHL FIX. The percentage of fully adherent patients (physician-reported) was similar in both treatment groups (SHL FIX, 68%; EHL FIX, 73%). In this preliminary real-world survey in a relatively small sample of patients, measures of ABR and adherence between SHL and EHL products were evaluated. Additional real-world research on prescribing patterns, SHL vs. EHL effectiveness, and adherence is warranted.

Haemophilia 2020; 27:e22-e29. [PMID: 33012106 DOI: 10.1111/hae.14159] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Revised: 08/17/2020] [Accepted: 09/04/2020] [Indexed: 02/06/2023]
Abstract
INTRODUCTION Increased usage of emicizumab in the United States will affect standard half-life (SHL) and extended half-life (EHL) products usage and cost. AIM To model the usage and cost of SHL and EHL products, and emicizumab to treat haemophilia A (HA) in the 13 Western States Region IX haemophilia treatment centres (HTCs.) (California, Nevada, Hawaii and Guam). METHODS We modelled product usage and cost using decision analysis methods. VARIABLES epidemiology/demographics, treatment and product cost. Data were from the US Western States Region IX, US Centers for Disease Control and Prevention, American Thrombosis and Hemostasis Network and the literature. RESULTS Prior to EHL products and emicizumab, the usage of SHL products was ~300 million international units (IUs) or 6.8 IUs/capita and a cost of $430 million. With the uptake of EHL and emicizumab, the 2025 estimated usage of factor (SHL and EHL) was 270 million IUs (5.4 IU per capita) and 1,993 grams (40 micrograms/capita) for emicizumab and a cost of $532 million. As the number of HA patients in the region increases by 59%, factor usage increases by 20%, emicizumab usage increases by 26%, and cost increases to $650 million. CONCLUSION The entrance of emicizumab into the market may radically change the use of SHL and EHL products. Our model suggests that emicizumab use will likely increase total product costs. While our estimates are most useful for the United States, the effect of emicizumab on factor use will likely be similar in other parts of the world.

Haemophilia 2020; 26 Suppl 5:21-29. [PMID: 32935399 DOI: 10.1111/hae.14082] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 05/24/2020] [Accepted: 05/28/2020] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Emicizumab is a humanized monoclonal modified IgG4 antibody with bispecific antibody structure bridging Factor IXa and Factor X. Emicizumab has demonstrated efficacy and safety in adults, adolescents and paediatrics with HA, with or without inhibitors to Factor VIII (FVIII). There is currently no evidence that reports on the potential impact of the introduction of emicizumab on the societal costs of haemophilia A (HA). The purpose of this study was to explore the cost impact associated with the introduction of emicizumab on the current societal costs of people with HA (PwHA) in Australia. METHODS We conducted an analysis of the impact of emicizumab on societal costs, based on changes in the direct and indirect costs incurred by PwHA. Potential impacts of emicizumab on outcomes in PwHA were modelled based on HAVEN 1, HAVEN 2 and HAVEN 3 studies. We assumed that eligible PwHA commenced use of emicizumab on 1 January 2018. The impact of emicizumab on costs of HA in Australia males was then estimated for the 12-month period to 31 December 2018. RESULTS Overall, uptake of emicizumab in its first year of use reduces annual costs associated with moderate/severe HA by AUD$69.197M (62.3%). This reflects 64.2% reduction in the cost of FVIII blood products and 92% reduction in cost of bypassing agents. CONCLUSION The cost of emicizumab is likely to offset some or all of the projected reductions in treatment costs. However, we also found 30.7% reduction in non-treatment direct costs (AUD$3.771M) and 19.1% reduction in indirect costs (AUD$2.732M).

Abstract
INTRODUCTION Few studies, both in Australia and overseas, have examined the social impacts of living with haemophilia A (HA) or the economic costs associated with the disorder. The purpose of this paper is to examine the epidemiology and societal burden of people with HA (PwHA) in Australia, with a particular focus on men with this disorder. METHODS The epidemiology and societal burden of HA in Australia, with a particular focus on men with this disorder, were assessed, using data available in the Australian and international literature and publicly available data. RESULTS The mean annual prevalence of HA is approximately 1-2 per 10 000 males. Prophylactic treatment is used in one-quarter (25.1%) of people with moderate HA, and 82.2% of people with severe HA. Within the latter group, 16.1% have inhibitors for Factor VIII, predisposing them to worse morbidity, mortality and quality of life when compared to the non-inhibitor population. Joint pain and joint disease occur commonly in PwHA, with up to 70% of adults with HA experiencing joint problems. HA is associated with poor physical health, and PwHA miss school and work due to bleeding-related events. CONCLUSION HA is associated with substantial economic burden; with large differences in costs reported between countries. Overall, HA imposes a significant burden of disease on PwHA, their families and the community at large.

Abstract
AIMS Haemophilia A patients with factor VIII inhibitors (HAPI) experience frequent spontaneous bleeding, approximately once a week, and require expensive bypassing agent (BPA) treatments to control bleeding over their lifetime. According to the HAVEN 1 trial, weekly emicizumab (Hemlibra®) prophylaxis injection reduces annualized bleeding rates (ABR) by 87% compared with BPA on-demand treatment (BPA-OD) administered at the time of bleeding. Our study aimed to assess the cost-effectiveness of emicizumab prophylaxis in HAPI in Korea. METHODS Using a lifetime Markov model with health states of 'alive with bleeds' and 'dead', we simulated the experience of HAPI receiving emicizumab prophylaxis (treatment arm) or BPA-OD (control arm) and estimated expected clinical and economic outcomes under each treatment arm. Model parameters included comparative effectiveness, clinical and epidemiologic characteristics of Korean HAPI, costs of drug treatment and medical events and utility for 'alive with bleeds' state under each treatment. We utilized local data, including National Health Insurance claims data, national statistics, literature and expert surveys with haematologists. RESULTS Base-case analysis results showed that compared with BPA-OD, lifetime emicizumab prophylaxis prevented 807 bleedings, extended 3.04 quality-adjusted life-years and reduced costs by 2.6 million US dollars. Thus, emicizumab prophylaxis is a dominant treatment option with better effectiveness and lower costs than BPA-OD. A series of one-way sensitivity analyses consistently showed dominant results, confirming that lifetime emicizumab prophylaxis is a cost-saving intervention for HAPI. CONCLUSION Emicizumab prophylaxis is an excellent treatment choice reducing ABR, improving quality of life and reducing costs.

Abstract
INTRODUCTION Haemophilia is an orphan and high-cost disease worldwide and, especially in middle-income countries as Colombia. Given its burden of disease, in 2014, a national administrative registry was created to centralize demographic, clinical and economic information regarding to haemophilia and other coagulopathies. OBJECTIVE To describe the building and implementation processes of the Colombian registry of haemophilia and other coagulopathies. METHODS The 'consensus conference' methodology was used to design the registry. It was a multisector process, which included different actors of the health system (healthcare payers and providers, government institutions, academic and scientific organizations and patients). RESULTS Colombia's national registry includes 95 variables, grouped in four sections: (1) sociodemographic data, (2) clinical condition, (3) economic costs, and (4) administrative updates. According to a resolution, stated by the Ministry of Health, payers and providers of healthcare must report annually to the registry the information of new and existing patients with coagulopathies. CONCLUSIONS A national registry serves as an organized and interactive system for monitoring morbidity and mortality, assessing healthcare access and its impact on disease complications, as well as associated costs to medical assistance. Furthermore, registry information can guide a rational making decision process to use economic resources efficiently. On the other hand, data about orphan diseases can encourage health research and evidence-based care to improve quality of life and reduce associated disability.

Abstract
BACKGROUND Hemophilia A (HA) can result in bleeding events because of low or absent clotting factor VIII (FVIII). Prophylactic treatment for severe HA includes replacement FVIII infusions and emicizumab, a bispecific factor IXa- and factor X-directed antibody. OBJECTIVE To develop an economic model to predict the short- and long-term clinical and economic outcomes of prophylaxis with emicizumab versus short-acting recombinant FVIII among persons with HA in the United States. METHODS A Markov model was developed to compare clinical outcomes and costs of emicizumab versus FVIII prophylaxis among persons with severe HA from U.S. payer and societal perspectives. Patients started prophylaxis at age 1 year in the base case. Mutually exclusive health states considered were "no arthropathy," "arthropathy," "surgery," and "death." Serious adverse events, breakthrough bleeds, and inhibitor development were simulated throughout the modeled time horizon. In addition to the prophylaxis drug costs, patients could incur other direct costs related to breakthrough bleeds treatment, serious adverse events, development of inhibitors, arthropathy, and orthopedic surgery. Indirect costs associated with productivity loss (i.e., missed work or disabilities) were applied for adults. Model inputs were obtained from the HAVEN 3 trial, published literature, and expert opinion. The model used a lifetime horizon, and results for 1 year and 5 years were also reported. Deterministic sensitivity analyses and scenario analyses were conducted to assess robustness of the model. RESULTS Over a lifetime horizon, the cumulative number of all treated bleeds and joint bleeds avoided on emicizumab versus FVIII prophylaxis were 278.2 and 151.7, respectively. Correspondingly, arthropathy (mean age at onset: 12.9 vs. 5.4 years) and FVIII inhibitor development (mean age at development: 13.9 vs. 1.1 years) were delayed. Total direct and indirect costs were lower for emicizumab versus FVIII prophylaxis for all modeled time horizons ($97,159 vs. $331,610 at 1 year; $603,146 vs. $1,459,496 at 5 years; and $15,238,072 vs. $22,820,281 over a lifetime horizon). The sensitivity analyses indicated that clinical outcomes were sensitive to efficacy inputs, while economic outcomes were driven by the discount rate, dosing schedules, and treatments after inhibitor development. Results for moderate to severe patients were consistent with findings in the severe HA population. CONCLUSIONS The model suggests that emicizumab prophylaxis confers additional clinical benefits, resulting in a lower number of bleeding events and delayed onset of arthropathy and inhibitor development across all time assessment horizons. Compared with short-acting recombinant FVIII, emicizumab prophylaxis leads to superior patient outcomes and cost savings from U.S. payer and societal perspectives.
