Abstract
BACKGROUND Etranacogene dezaparvovec is a recently approved gene therapy for people with hemophilia B (PwHB). Current standard of care is prophylaxis with factor IX (FIX) to prevent bleeding. Etranacogene dezaparvovec increases blood FIX levels such that FIX prophylaxis could be eliminated. OBJECTIVE To estimate the budgetary impact of etranacogene dezaparvovec adoption and utilization in a commercial health plan of the United States. METHODS A budget impact model was developed to evaluate the introduction of etranacogene dezaparvovec to treat severe or moderately severe hemophilia B. The model considered a hypothetical 1-million-member plan over a 5-year horizon. FIX therapy prophylaxis use was estimated based on a weighted average of relevant brands using US market share data. A scenario of etranacogene dezaparvovec adoption/utilization was compared with one without etranacogene dezaparvovec utilization. Two etranacogene dezaparvovec uptake (market share growth) analyses were performed: one with gradual uptake and alternatively assuming all eligible PwHB received etranacogene dezaparvovec in year 1. The one-time cost of etranacogene dezaparvovec was assumed to be $3.5 million. Other costs (FIX prophylaxis, disease monitoring, bleed management, and adverse events) were estimated from published literature. All costs were in 2022 US dollars. Bleed and adverse event rates were sourced from the HOPE-B trial comparing etranacogene dezaparvovec to previous FIX therapy prophylaxis. The model estimated annual and per-member per-month costs over 5 years. Secondary analyses were performed considering a 10-year horizon. RESULTS In the 1-million-member health plan, an estimated 1.8 PwHB were eligible for treatment with etranacogene dezaparvovec. Gradual uptake of etranacogene dezaparvovec resulted in cumulative 5-year budget impact of $848,509 compared with a scenario without etranacogene dezaparvovec. In years 1-5, the incremental annual and per-member per-month costs ranged from $79,824 to $271,435 and from $0.007 to $0.023, respectively. In the alternative uptake analysis, etranacogene dezaparvovec became cost saving annually beginning in year 2 and cumulatively beginning in year 5, for a 5-year savings of $754,844. Secondary analyses over 10 years found both uptake analyses cost saving. Other scenarios considered did not affect results substantially. CONCLUSIONS Introducing etranacogene dezaparvovec as treatment for PwHB would have a modest budget increase within 5 years after treatment but may become cost saving if all eligible PwHB were treated in year 1. Initiating PwHB on etranacogene dezaparvovec sooner may produce greater overall savings and earlier annual savings. Etranacogene dezaparvovec is a treatment option that may provide overall cost savings for US commercial health plans, which would increase as the plan size increases.

Abstract
INTRODUCTION As a result of centralisation of haemophilia care to a limited number of intramural settings, many persons with haemophilia have to travel long distances to attend their haemophilia specialised treatment centre. However, regular physiotherapy treatment can be provided by primary care physiotherapists in the person's own region. Due to the rarity of the disease most primary care physiotherapists have limited experience with this population. This study aims to provide a clinical practice guideline for primary care physiotherapists working with persons with bleeding disorders. METHOD A list of the most urgent key-questions was derived from a previous study. Literature was summarised using the grading of recommendations assessment, development, and evaluation (GRADE) evidence-to-decision framework. Recommendations were drafted based on four 90 min consensus meetings with expert physiotherapists. Recommendations were finalised after feedback and >80% consensus of all stakeholders (including PWH, physiotherapists, haematologists and the corresponding societies). RESULTS A list of 82 recommendations was formulated to support primary care physiotherapists when treating a person with a bleeding disorder. These recommendations could be divided into 13 categories: two including recommendations on organisation of care, six on therapy for adult patients with bleeding disorders and five on therapy adaptations for paediatric care. Therapy recommendations included treatment after a joint- or muscle bleed, haemophilic arthropathy, chronic synovitis, non-haemophilia related conditions and orthopaedic surgery. CONCLUSION An evidence-based practice guideline, based on current evidence from literature and clinical expertise, has been developed for primary care physiotherapists treating a person with haemophilia. To improve care, the recommendations should be implemented in daily practice.

Abstract
Managing hemophilia in patients undergoing joint replacement surgery requires a comprehensive approach encompassing preoperative assessment, meticulous intraoperative care, and tailored postoperative management. Evaluation of joint integrity, bleeding history, and inhibitor presence guides surgical planning and hemostatic therapy selection to optimize outcomes. During surgery, careful attention to factor replacement, antibiotic prophylaxis, anesthetic techniques, and orthopedic strategies minimizes bleeding risk and enhances surgical success. Postoperatively, effective pain management, continued hemostatic therapy, and individualized rehabilitation programs are vital for facilitating recovery and preventing complications. Close monitoring for potential complications, such as periprosthetic joint infection and recurrent hemarthrosis, allows for prompt intervention when necessary. Overall, a collaborative approach involving hematologists, orthopedic surgeons, anesthesiologists, and rehabilitation specialists ensures comprehensive care tailored to the unique needs of patients with hemophilia undergoing joint replacement surgery, ultimately optimizing outcomes and improving quality of life. This holistic approach addresses the multifaceted challenges posed by hemophilia and joint replacement surgery, providing patients with the best possible chance for successful outcomes and long-term joint function. By integrating specialized expertise from multiple disciplines and implementing evidence-based strategies, healthcare providers can effectively manage hemophilia in the context of joint replacement surgery, mitigating risks and maximizing benefits for patients.

Abstract
Haemophilia presents a significant challenge to the quality of life of affected individuals. Evaluating the health-related quality of life (HRQoL) of people with haemophilia (PwH) provides a valuable mean of assessing their perception of overall care outcomes, while also identifying influential factors across various age and condition severity demographics. This observational retrospective study determined the HRQoL of 100 adult PwH in Northern Greece through comprehensive analysis and interpretation of their HRQoL levels, particularly in domains concerning their physical, emotional, and mental well-being, obtained through the Haem-A-QoL index questionnaire. Disease severity and young age were significantly associated with the administration of prophylactic treatment (84.2% of patients with severe haemophilia and 65.2% of patients aged 18-30). The mean Haem-A-QoL score was 40.11 ± 17.38, with the lowest HRQoL observed in the 46-60 age group (46.16), and the highest in the ≥61 age groups (35.16). Notably, the 'Sports/Leisure' and 'Physical Health' domains exhibited the highest scores, in contrast to 'Family Planning' and 'Relationships/Sexuality'. Individuals with mild haemophilia recorded the lowest mean score (39.38), while those with a severe condition exhibited the highest (41.23). Age, disease severity, and physical activity emerged as primary determinants significantly affecting HRQoL outcomes.

Abstract
People with nonsevere hemophilia (PWNSH) are phenotypically more diverse than those with severe hemophilia. Perceptions relating to a "nonsevere" phenotype have contributed to fewer research initiatives, fewer guidelines on optimal management, and a lack of standards for surveillance and clinical assessment for affected individuals. In many cases, episodes of abnormal bleeding could, if investigated, have led to earlier diagnosis. Furthermore, the major recent developments in therapy for hemophilia have largely focused on severe disease and, as a group, PWNSH have not been included in many key clinical trials. Benefiting people with severe disease, innovative replacement therapies have generally targeted factor levels that are above those present in a large proportion of PWNSH. Therapeutic advances can lead to improvement in phenotype for people with severe hemophilia over that currently experienced by many PWNSH. As a result, we are approaching a point where PWNSH may, in many countries, have a higher risk of bleeding and restriction in lifestyle than those with severe disease but with more limited therapeutic options. Given the multiple major advances in treatment for people with hemophilia, it is timely to review the aspects of nonsevere disease, to ensure equity in care and management for all individuals with this condition.

Abstract
Background Joint bleeding can lead to synovitis and arthropathy in people with hemophilia, reducing quality of life. Although early diagnosis is associated with improved therapeutic outcomes, diagnostic ultrasonography requires specialist experience. Artificial intelligence (AI) algorithms may support ultrasonography diagnoses. Objectives This study will research, develop, and evaluate the diagnostic precision of an AI algorithm for detecting the presence or absence of hemarthrosis and synovitis in people with hemophilia. Methods Elbow, knee, and ankle ultrasound images were obtained from people with hemophilia from January 2010 to March 2022. The images were used to train and test the AI models to estimate the presence/absence of hemarthrosis and synovitis. The primary endpoint was the area under the curve for the diagnostic precision to diagnose hemarthrosis and synovitis. Other endpoints were the rate of accuracy, precision, sensitivity, and specificity. Results Out of 5649 images collected, 3435 were used for analysis. The area under the curve for hemarthrosis detection for the elbow, knee, and ankle joints was ≥0.87 and for synovitis, it was ≥0.90. The accuracy and precision for hemarthrosis detection were ≥0.74 and ≥0.67, respectively, and those for synovitis were ≥0.83 and ≥0.74, respectively. Analysis across people with hemophilia aged 10 to 60 years showed consistent results. Conclusion AI models have the potential to aid diagnosis and enable earlier therapeutic interventions, helping people with hemophilia achieve healthy and active lives. Although AI models show potential in diagnosis, evidence is unclear on required control for abnormal findings. Long-term observation is crucial for assessing impact on joint health.

Abstract
INTRODUCTION Due to advances in treatments, people with haemophilia (PWH) are living longer. They are not as active as the general population due to joint damage and lack confidence to be active due to concerns about further bleeds and pain. There is a need to facilitate healthy aging through promotion of physical activity (PA) and exercise. Changing patient beliefs and increasing physical literacy and confidence to move are thought to be key to helping PWH become more active. AIM This paper describes the development of an exercise and behaviour change intervention to improve confidence to exercise in PWH. METHODS The 4-stage Medical Research Council framework for complex intervention development was used. RESULTS Stakeholders included 17 PWH and 7 physiotherapists working in haemophilia. Seven online focus group meetings were held. The final intervention is a hybrid 12-week physiotherapist led progressive exercise programme. Classes are 45 min including Pilates, High intensity interval training and balance elements, together with discussion sessions focusing on PA recommendations, the types and benefits of different exercise styles and the effects of PA, together with the effects of aging for PWH. The COM-B model of behaviour change was used to develop the intervention. CONCLUSION Co-design helps to produce an intervention that understands the stakeholders needs. Through this process the intervention developed to incorporate not only increasing PA but also confidence to exercise. The use of behaviour change theory identified the behaviour techniques included in the intervention and aims to increase physical literacy in this population.

Abstract
BACKGROUND Hemophilic arthropathy usually affects the knees bilaterally. In order to reduce costs and improve rehabilitation, bilateral simultaneous total knee arthroplasty (TKA) can be performed. However, pharmacological prophylaxis for deep venous thrombosis (DVT) remains controversial in patients with severe hemophilia. The purpose of this study was to establish the incidence of DVT in severe hemophilia A patients undergoing bilateral simultaneous TKA without pharmacological thromboprophylaxis. METHODS Consecutive patients with severe hemophilia A undergoing bilateral simultaneous TKA at a single center between January 2015 and December 2020 were retrospectively reviewed. All patients received a modified coagulation factor substitution regimen. Tranexamic acid (TXA) was used for hemostasis in all patients during surgery. All patients followed a standardized postoperative protocol with routine mechanical thromboprophylaxis, and none received anticoagulation. D-dimer was measured preoperatively, on the day of the operation and on postoperative days 1, 7 and 14. Ultrasound (US) of the lower extremities was performed before (within 3 days of hospitalization) and after surgery (days 3 and 14) to detect asymptomatic DVT. Patients were followed up until 2 years after surgery for the development of symptomatic DVT or pulmonary embolism (PE). RESULTS 38 male patients with severe hemophilia A underwent 76 simultaneous TKAs. Mean (± standard deviation) age at the time of operation was 41.7 (± 17.1) years. Overall, 47.3% of patients had D-dimer concentrations above the threshold 10 µg/mL on day 7 and 39.5% on day 14. However, none of the patients had DVT detected on postoperative US, nor developed symptomatic DVT or PE during the 2-year follow-up. CONCLUSIONS The risk of DVT in patients with severe hemophilia A after bilateral simultaneous TKA is relatively low, and routine pharmacological thromboprophylaxis may not be needed.

Abstract
AIM For people with haemophilia A (PwHA), bleeding in the joints leads to joint damage and haemophilia-related arthropathy, impacting range of motion and life expectancy. Existing guidelines for managing haemophilia A support healthcare professionals (HCPs) and PwHA in their efforts to preserve joint health. However, such guidance should be reviewed, considering emerging evidence and consensus as presented in this manuscript. METHODS Fifteen HCPs experienced in the management of PwHA in the UK participated in a three-round Delphi panel. Consensus was defined at ≥70% of panellists agreeing or disagreeing for Likert-scale questions, and ≥70% selecting the same option for multiple- or single-choice questions. Questions not reaching consensus were revised for the next round. RESULTS 26.8% (11/41), 44.8% (13/29) and 93.3% (14/15) of statements reached consensus in Rounds 1, 2 and 3, respectively. HCPs agreed that prophylaxis should be offered to patients with a baseline factor VIII (FVIII) level of ≤5 IU/dL and that, where there is no treatment burden, the aim of prophylaxis should be to achieve a trough FVIII level ≥15 IU/dL and maintain a longer period with FVIII levels of ≥20-30 IU/dL to provide better bleed protection. The aspirational goal for PwHA is to prevent all joint bleeds, which may be achieved by maintaining normalised (50-150 IU/dL) FVIII levels. CONCLUSION The panel of experts were largely aligned on approaches to preserving joint health in PwHA, and this consensus may help guide HCPs.

Ozelo MC, Hermans C, Carcao M, Guillet B, Gu J, Guerra R, Tang L, Khair K. The effectiveness and safety of octocog alfa in patients with hemophilia A: up to 7-year follow-up of the real-world AHEAD international study. Ther Adv Hematol 2024; 15:20406207231218624. [PMID: 38371314 PMCID: PMC10874143 DOI: 10.1177/20406207231218624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 11/16/2023] [Indexed: 02/20/2024] Open
Abstract
Background Real-world data assessing treatment outcomes in patients with hemophilia A in routine clinical practice are limited. Objective To evaluate the effectiveness and safety of octocog alfa in patients with moderate/severe hemophilia A receiving treatment in clinical practice. Design The international Antihemophilic Factor Hemophilia A Outcome Database study is an observational, noninterventional, prospective, multicenter study. Methods This planned interim data read-out was conducted following 7 years of observation of patients receiving octocog alfa (cut-off, 30 June 2020). The primary endpoint was joint health status, assessed by the Gilbert Score. Secondary endpoints included annualized bleeding rates (ABRs), Hemophilia Joint Health Score (HJHS), health-related quality of life, consumption, and safety. This post hoc analysis stratified data by hemophilia severity at baseline [moderate, factor VIII (FVIII) 1-5%; severe, FVIII <1%]. Results Of the 711 patients in this analysis, 582 (82%) were receiving prophylaxis with octocog alfa at enrollment, and 498 (70%) had severe disease. Median Gilbert Scores were higher with on-demand therapy versus prophylaxis and scores were comparable in moderate and severe disease. In patients receiving prophylaxis, there was an improvement in HJHS Global Gait Score over 7 years of follow-up overall and in patients with severe disease. ABRs and annualized joint bleeding rates were low across all 7 years. An ABR of zero was reported in 34-56% of prophylaxis patients versus 20-40% in the on-demand group. ABRs were similar in severe and moderate disease. In total, 13/702 (1.9%) patients experienced 18 treatment-related adverse events. Conclusion These data demonstrate the long-term effectiveness and safety of octocog alfa in patients with moderate and severe hemophilia A, especially in those receiving prophylaxis. The high number of patients receiving on-demand treatment experiencing zero bleeds could be due to selection bias within the study, with patients with less severe disease more likely to be receiving on-demand treatment. Trial registration ClinicalTrials.gov: NCT02078427.

Long-term outcomes with emicizumab in hemophilia A without inhibitors: results from the HAVEN 3 and 4 studies. Res Pract Thromb Haemost 2024; 8:102364. [PMID: 38559572 PMCID: PMC10978536 DOI: 10.1016/j.rpth.2024.102364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 02/14/2024] [Indexed: 04/04/2024] Open
Abstract
Background Emicizumab, a bispecific monoclonal antibody, bridges activated factor (F) IX and FX, mimicking the function of missing or deficient activated FVIII in people with hemophilia A (HA). Objectives To evaluate the long-term efficacy and safety of emicizumab prophylaxis in people with HA without FVIII inhibitors in the HAVEN 3 and 4 studies. Methods HAVEN 3 and 4 were phase 3 open-label studies. Participants received emicizumab maintenance doses of 1.5 mg/kg every week or 3 mg/kg every 2 weeks (HAVEN 3), or 6 mg/kg every 4 weeks (HAVEN 4). Long-term efficacy and safety were assessed. Results A total of 151 and 40 individuals without FVIII inhibitors received emicizumab in HAVEN 3 and 4, respectively. At the last patient, last visit dates (May 12, 2022 [HAVEN 3] and June 29, 2022 [HAVEN 4]), the median (range) duration of emicizumab exposure across the 2 studies was 248.1 (6.1-287.1) weeks. The mean (95% CI) annualized bleed rate for treated bleeds was 2.0 (0.23-7.15) for weeks 1 to 24, decreasing to 0.9 (0.01-5.28) by weeks 217 to 240. Overall, 188 (98.4%) participants experienced ≥1 adverse event (AE), with 185 treatment-related AEs in 71 (37.2%) participants. Forty-four (23.0%) participants reported a serious AE. Two thromboembolic events were reported, which were deemed unrelated to emicizumab by the investigator. No thrombotic microangiopathies were reported. Conclusion With nearly 5 years of emicizumab exposure across the HAVEN 3 and 4 studies in people with HA without inhibitors, these data indicate continued bleed control with no new safety signals observed during long-term follow-up.

Res Pract Thromb Haemost 2024; 8:102355. [PMID: 38496709 PMCID: PMC10941006 DOI: 10.1016/j.rpth.2024.102355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 01/13/2024] [Accepted: 02/09/2024] [Indexed: 03/19/2024] Open
Abstract
Background Arthropathy following repeated bleeding is common in persons with hemophilia. Since the introduction of prophylaxis, treatment has intensified and joint health has improved. However, data on the long-term development of arthropathy are still scant. Objectives To evaluate long-term arthropathy development since the introduction of prophylaxis according to birth cohort, hemophilia severity, and inhibitor status. Methods This single-center historic cohort study included persons with severe and moderate hemophilia A and hemophilia B born between 1935 and 2005. Arthropathy on X-rays was evaluated using the Pettersson score. Patient and joint characteristics were studied per birth cohort (<1970, 1970-1980, 1981-1990, and >1990) and compared according to hemophilia severity. The distribution of affected joints and cumulative incidence of arthropathy were analyzed. The association of Pettersson score with birth cohort and inhibitor characteristics was explored using multivariable regression analyses adjusted for age at evaluation. Results In total, 1064 X-rays of 363 patients were analyzed. Of persons with severe hemophilia (n = 317, 87.3%), 244 (77.0%) developed arthropathy. Prophylaxis was started at younger ages over time, from a median of 18 to 2.1 years, and concomitantly, arthropathy decreased in consecutive birth cohorts. Ankles were most commonly affected in 188 of 258 (72.9%) patients. Persons with moderate hemophilia (n = 46, 12.7%) had a lower risk of arthropathy (27/46 [58.7%]), but a reduction over time was less pronounced. In the multivariable analyses, birth cohort and age at evaluation were predictors for the development of arthropathy, while inhibitor status showed no association. Conclusion The development and severity of arthropathy have decreased over the past decades. However, patients have remained at risk for developing arthropathy, especially in their ankles.

Abstract
BACKGROUND Hemophilia is a rare genetic condition that is often overlooked and underdiagnosed, particularly in low-income countries. Long-term spontaneous joint bleeding and soft tissues can have a significant negative impact on a patient's health-related quality of life (HRQoL). The objective of this study was to assess HRQoL and its associated factors in Ethiopian patients with hemophilia. METHODS A cross-sectional survey was conducted among patients with hemophilia at Tikur Anbessa Specialized Hospital (TASH) in Addis Ababa, Ethiopia. Patients were recruited consecutively during follow-up visits. The European Quality of Life Group's 5-Domain Questionnaires at five levels (EQ-5D-5L) and Euro Quality of Life Group's Visual Analog Scale (EQ-VAS) instruments were used to assess HRQoL. The EQ-5D-5L utility score was computed using the disutility coefficients. We applied the Krukal-Wallis and Mann-Whitney U tests to determine the differences in EQ-5D-5L and EQ-VAS utility scores between patient groups. A multivariate Tobit regression model was used to identify factors associated with HRQoL. Statistical analyses were performed using STATA version 14 and statistical significance was determined at p < 0.05. RESULTS A total of 105 patients with hemophilia participated in the study, with a mean (standard deviation (SD) age of 21.09 (± 7.37] years. The median (IQR) EQ-5D-5L utility and EQ-VAS scores were 0.86 (0.59-0.91) and 75 (60.0-80.0), respectively. Age was significantly negatively associated with the EQ-5D-5L utility index and EQ-VAS (β = -0.020, 95 CI = -0.034, -0.007) and β = -0.974, 95% CI = -1.72, 0.225), respectively. The duration since hemophilia diagnosis (β-0.011, 95% CI, 0.001-0.023) and living out of Addis Ababa (β = -0.128, 95% CI, -0.248-, -0.007) were also significantly negatively associated with the EQ-5D-5L utility index.. CONCLUSION The median EQ-5D-5L utility and EQ-VAS scores of patients with hemophilia were 0.86 (0.59-0.91) and 75 (60.0-80.0), respectively. Older age, living far from the Hemophilia Treatment Center (HTC), and longer duration since diagnosis were significantly negatively associated with HRQoL. HRQoL may be improved by providing factor concentrates, decentralizing HTCs in different parts of the country, increasing awareness of bleeding disorders among health professionals, and providing psychosocial support to affected patients.

Abstract
BACKGROUND Haemophilia is a haematological disease, although most haemorrhages occur in the locomotor system. Patients are physically disabled from an early age and have a poorer perception of quality of life. In the day-to-day lives of patients and their families, psychosocial well-being, the disease's physical, personal, and social impact, as well as work-related problems are the most complicated aspects of the disease that need to be addressed. OBJECTIVE To identify the role of occupational therapy in managing patients with haemophilia and to analyse the therapeutic potential of occupational therapy in treating these patients. METHODS A scoping review was conducted to identify the role of occupational therapy in managing patients with haemophilia and to analyse the therapeutic potential of occupational therapy in treating these patients. The review was registered in the international registry PROSPERO (Id: CRD42022319637). The databases consulted were SCOPUS, PubMed, PsycINFO, Web of Science and Science Direct, including all studies published until 14 August 2023. RESULTS No single study was found that specifically developed an occupational therapy intervention for patients with haemophilia. Measurement instruments have been identified, specific for patients with haemophilia and generic, that can be useful for the functional evaluation of these patients in the occupational therapy approach. Different studies showed the importance of multidisciplinary treatment, including occupational therapy. CONCLUSIONS The use of occupational therapy could be effective in improving autonomy and quality of life in haemophilia patients. Therefore, it is of paramount importance to conduct research studies within the field of occupational therapy.

Surgical Experience from the STASEY Study of Emicizumab Prophylaxis in People with Hemophilia A with Factor VIII Inhibitors. TH OPEN 2024; 8:e42-e54. [PMID: 38222041 PMCID: PMC10786707 DOI: 10.1055/s-0043-1777766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 10/28/2023] [Indexed: 01/16/2024] Open
Abstract
Background Guidelines surrounding emicizumab prophylaxis and perioperative treatment for people with hemophilia A (PwHA) with factor (F)VIII inhibitors undergoing surgeries are limited. The phase IIIb multicenter, single-arm STASEY study evaluated safety and tolerability of emicizumab prophylaxis in PwHA aged ≥12 years with FVIII inhibitors. This analysis assesses surgeries during study conduct, associated hemophilia medications, and postoperative bleeds (treated and untreated). Methods PwHA with FVIII inhibitors received emicizumab 3.0 mg/kg/week for 4 weeks, then 1.5 mg/kg/week until 2 years. Surgeries were managed and documented by treating physicians. Bleeds and treatments were recorded by physicians and participants. Results Forty-six participants had ≥1 on-study surgery, 37 underwent 56 minor surgeries, and 13 underwent 22 major surgeries. Four participants underwent both minor and major surgeries. Of 18 (81.8%) and 4 (18.2%) major surgeries managed with/without additional hemostatic medication, 33.3 and 25.0% were associated with a treated postoperative bleed, respectively. Of 24 (42.9%) and 32 (57.1%) minor surgeries managed with/without additional hemostatic medication, 15.6 and 25.0% were associated with a treated postoperative bleed, respectively. Recombinant activated FVII was the most common medication for prophylaxis and bleed treatment. There were no thrombotic microangiopathies (TMAs). One hypertrophic clot, considered unrelated to emicizumab, occurred following tooth extraction. Conclusion In this challenging population with a high bleeding risk, major surgeries were performed in PwHA receiving emicizumab with/without additional hemostatic medication. Postoperative bleeds occurred following 59.1% of major surgeries; 53.8% were treated. No arterial/venous thrombotic events or TMAs occurred due to concomitant emicizumab and bypassing agents. Trial registration This trial is registered at ClinicalTrials.gov (NCT03191799).

Abstract
Hemophilia is a plasma bleeding disorder characterized by a deficiency of certain blood clotting factors. The most common forms of this disease, i.e., type A and type B, affect approximately 400,000 people worldwide. Without appropriate treatment ensuring the proper coagulation cascade, this disease may lead to serious disability. Minimizing patient discomfort is possible via replacement therapy, consisting of the substitution of a missing coagulation factor via intravenous administration. Frequent medication and the risk related to factor inhibitors are significant disadvantages, necessitating the improvement of current therapies or the development of novel ones. This review examines the humanized bispecific antibody Emicizumab which ensures hemostasis by mimicking the action of the coagulation factor VIII, a deficiency of which causes type A hemophilia. The paper outlines the topic and then summarizes available clinical trials on Emicizumab in type A hemophilia. Several interventional clinical trials have found Emicizumab to be effective in decreasing bleeding episodes and raising patient satisfaction among various hemophilia A populations. Current Emicizumab-related trials are forecast to be completed between 2024 and 2030, and in addition to congenital hemophilia A, the trials cover acquired hemophilia A and patients playing sports. Providing a more comprehensive understanding of Emicizumab may revolutionize the management of hemophilia type A and improve quality of life. Conclusively, Emicizumab is a gentler therapy owing to subcutaneous delivery and fewer injections, which reduces injection-site reactions and makes therapy less burdensome, ultimately decreasing hospital visits and indirect costs.

Analysis of long-term clinical and cost impact of etranacogene dezaparvovec for the treatment of hemophilia B population in the United States. J Med Econ 2024; 27:758-765. [PMID: 38708771 DOI: 10.1080/13696998.2024.2351762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Accepted: 05/02/2024] [Indexed: 05/07/2024]
Abstract
INTRODUCTION Etranacogene dezaparvovec (EDZ), Hemgenix, is a gene therapy recently approved for people with hemophilia B (PwHB). OBJECTIVE To estimate long-term clinical impact and cost of EDZ in the United States (US). METHODS A decision-analytic model was developed to evaluate the long-term impact of introducing EDZ for PwHB over a 20-year time horizon. Factor IX (FIX) prophylaxis comparator was a weighted average of different FIX prophylaxis regimens based on US market share data. We compared a scenario in which EDZ is introduced in the US versus a scenario without EDZ. Clinical inputs (annualized FIX-treated bleed rate; adverse event rates) were obtained from HOPE-B phase 3 trial. EDZ durability input was sourced from an analysis predicting long-term FIX activity with EDZ. EDZ one-time price was assumed at $3.5 million. Other medical costs, including FIX prophylaxis, disease monitoring, bleed management, and adverse events were from literature. The model estimated annual and cumulative costs, treated bleeds, and joint procedures over 20 years from EDZ introduction. RESULTS Approximately 596 PwHB were eligible for EDZ. EDZ uptake was estimated to avert 11,282 bleeds and 64 joint procedures over 20 years. Although adopting EDZ resulted in an annual excess cost over years 1-5 (mean: $53 million annually, total $265 million), annual cost savings were achieved beginning in year 6 (mean: $172 million annually; total $2.58 billion in years 6-20). The total cumulative 20-year cost savings was $2.32 billion, with cumulative cost savings beginning in year 8. CONCLUSION Introducing EDZ to treat PwHB is expected to result in cost savings and patient benefit over 20 years. Initiating PwHB on EDZ sooner can produce greater and earlier savings and additional bleeds avoided. These results may be a conservative estimate of the full value of EDZ, as PwHB would continue to accrue savings beyond 20 years.

Abstract
BACKGROUND Improved approaches for chronic pain management are a clinical and research priority for people with haemophilia (PWH). Involving people with lived experience in the design of a complex rehabilitation intervention strengthens the credibility and plausibility of the intervention, particularly in relation to rare disorders. Here we describe using a 'Theory of Change' (ToC) dialogue-based stakeholder process to create a programme theory for a telerehabilitation intervention. METHODS An online workshop was convened and stakeholders received a briefing document in advance. Five stakeholders took part (3 PWH and 2 physiotherapists). At the workshop the group first agreed the overall aim of the intervention. Discussions then identified the resources, activities, barriers and enablers needed to achieve this outcome. All discussions were recorded and annotated by the workshop moderator. Behaviour change techniques were mapped for inclusion in the theory. RESULTS A programme theory and narrative report were produced. All stakeholders reviewed these for clarity and to ensure a true reflection of the workshop discussions. Agreement was based on how meaningful, well-defined, do-able, plausible, credible, and testable each component was. Stakeholders highlighted the importance of issues unique to PWH. Key components included the need for physiotherapists to be knowledgeable of the condition, a range of exercises that were inclusive of all abilities, and the need for people to feel safe and supported whilst taking part. CONCLUSIONS Co-developed theory based approaches to intervention design offer an inclusive and transparent way to develop novel and meaningful interventions for people with complex health conditions. The ToC is wholly transparent in its design and content. Together with the identified behaviour change techniques, the theory informs the protocol for a feasibility study evaluating a telerehabilitation intervention. Importantly, it allows the opportunity to revise, adapt and improve the programme theory for further implementation and evaluation.

Abstract
BACKGROUND Arthropathy is a common complication in patients with hemophilia. We examined the prevalence of this skeletal complication in patients with hemophilia who were registered at a Comprehensive Hemophilia Center in Shiraz, Southern Iran. MATERIALS AND METHODS In this cross-sectional study, an orthopedic specialist visited 448 patients and conducted screenings for skeletal complications. The assessment included evaluating the type of hemophilia, disease severity, treatment modality, the presence of inhibitors, and the identification of skeletal complications. RESULTS Ninety patients with hemophilia A, with a mean age (SD) of 31.6 (14.4) years, and 10 patients with hemophilia B, with a mean age of 30.5 (20.6) years, were assessed. The most frequently affected joints were the knee and ankle joints. In the univariate analysis, patients with severe disease were more likely to exhibit synovitis, a target joint, and bone disease compared to patients with non-severe disease. Additionally, a history of treated or active hepatitis and an annual bleeding rate showed significant associations with the target joint. In the multivariable logistic regression analysis, disease severity (OR 14.43, 95% CI 1.6-129.6) and a higher age at diagnosis (OR 1.06, 95% CI 1.00-1.13) increased the likelihood of developing osteoporosis. A history of hepatitis (OR 3.67, 95% CI 1.28-10.48) was identified as an independent risk factor for the target joint. CONCLUSION Skeletal complications are a common occurrence in hemophilia. Regular consultations with orthopedic specialists, focusing on bleeding control and hepatitis prevention, are essential for reducing the impact of this debilitating complication.

Abstract
BACKGROUND The first stage of fracture healing consists of hematoma formation with recruitment of proinflammatory cytokines and matrix metalloproteinases. Unfortunately, when there is an intra-articular fracture, these inflammatory mediators are not retained at the fracture site, but instead, envelop the healthy cartilage of the entire joint via the synovial fluid fracture hematoma (SFFH). These inflammatory cytokines and matrix metalloproteinases are known factors in the progression of osteoarthritis and rheumatoid arthritis. Despite the known inflammatory contents of the SFFH, little research has been done on the effects of the SFFH on healthy cartilage with regard to cell death and alteration in gene expression that could lead to posttraumatic osteoarthritis (PTOA). METHODS SFFH was collected from 12 patients with intraarticular ankle fracture at the time of surgery. Separately, C20A4 immortalized human chondrocytes were 3-dimensionally cultured to create scaffold-free cartilage tissue analogs (CTAs) to simulate healthy cartilage. Experimental CTAs (n = 12) were exposed to 100% SFFH for 3 days, washed, and transferred to complete media for 3 days. Control CTAs (n = 12) were simultaneously cultured in complete medium without exposure to SFFH. Subsequently, CTAs were harvested and underwent biochemical, histological, and gene expression analysis. RESULTS Exposure of CTAs to ankle SFFH for 3 days significantly decreased chondrocyte viability by 34% (P = .027). Gene expression of both COL2A1 and SOX9 were significantly decreased after exposure to SFFH (P = .012 and P = .0013 respectively), while there was no difference in COL1A1, RUNX2, and MMP13 gene expression. Quantitative analysis of Picrosirius red staining demonstrated increased collagen I deposition with poor ultrastructural organization in SFFH-exposed CTAs. CONCLUSION Exposure of an organoid model of healthy cartilage tissue to SFFH after intraarticular ankle fracture resulted in decreased chondrocyte viability, decreased expression of genes regulating normal chondrocyte phenotype, and altered matrix ultrastructure indicating differentiation toward an osteoarthritis phenotype. CLINICAL RELEVANCE The majority of ankle fracture open reduction and internal fixation does not occur immediately after fracture. In fact, typically these fractures are treated several days to weeks later in order to let the swelling subside. This means that the healthy innocent bystander cartilage not involved in the fracture is exposed to SFFH during this time. In this study, the SFFH caused decreased chondrocyte viability and specific altered gene expression that might have the potential to induce osteoarthritis. These data suggest that early intervention after intraarticular ankle fracture could possibly mitigate progression toward PTOA.

Abstract
Hemophilia is a chronic, congenital/hereditary and X-linked disease, characterized by an insufficiency of factors VIII or IX, which are necessary for blood clotting. Those affected by hemophilia often suffer from particular psychosocial problems, both in the acceptance, coping, treatment and self-management of their disease and in their family and social relationships, which are often mediated by these circumstances. The aim of this study was to explore the experiences of people with hemophilia or their family members, of in a specific region of Spain, regarding the impact of having hemophilia. Structured interviews were conducted and developed, using the studies of the World Federation of Hemophilia and Osorio-Guzmán et al. as a guide, as well as a literature review of qualitative work on hemophilia. Data were analyzed using a six-step thematic analysis. A total of 34 interviews were thematically analyzed. The results showed that three key themes emerged from the data: (1) the daily impact of having hemophilia, (2) uncertainty about the disease, (3) the role of associations and (4) support from institutions. The results make it clear that the disease has a major impact on their lives (work, family, leisure and personal environment). The main conclusion is that hemophilia has a negative impact on the daily lives of patients, families and caregivers.

Abstract
Background Recurrent joint bleeds are a major cause of morbidity in severe hemophilia. Prophylaxis with efmoroctocog alfa (a recombinant factor VIII Fc fusion protein, [rFVIIIFc]) has demonstrated benefits beyond bleed control, including joint health maintenance. Objectives To assess long-term efficacy and safety of rFVIIIFc prophylaxis in severe hemophilia A in phase 3 pivotal (A-LONG/Kids A-LONG) and extension (ASPIRE) studies. Methods Longitudinal analysis included pooled data from A-LONG/Kids A-LONG and ASPIRE. Subgroup analyses investigated outcomes in modified Hemophilia Joint Health Score or Hemophilia Joint Health Score and target joints in subjects with 4 to 5 years follow-up on individualized prophylaxis (IP), and those with the highest annualized bleeding rate (ABR) quartile during Year 1 of IP. Results Overall, rFVIIIFc consumption remained stable and low ABRs were maintained, with a median treatment duration of 4.2/3.4 years in subjects from A-LONG/Kids A-LONG, respectively. Median overall ABR also remained low (1.0-2.0) in subjects on IP for 4 to 5 years. Sustained improvements in modified Hemophilia Joint Health Score or Hemophilia Joint Health Score were demonstrated over a median follow-up of 3.7 years. In subjects from A-LONG/Kids A-LONG, 99.6% (n = 234)/100% (n = 9) of evaluable baseline target joints were resolved, with no recurrence in 95%/100% of target joints. In IP subjects within the highest ABR quartile in Year 1, continued improvements were observed over a median follow-up of 4.3 years in ABR and joint health, without increased factor consumption. No inhibitors or treatment-related serious adverse events were reported. Conclusion Previously treated subjects of all ages receiving long-term prophylaxis with rFVIIIFc had sustained clinical benefits, including improved joint health and low ABR.

Abstract
Background In hemophilia, recurrent hemarthrosis may lead to irreversible arthropathy. T2 mapping MRI may reflect cartilage changes at an earlier reversible stage of arthropathy as opposed to structural MRI. Objectives To evaluate interval changes of T2 mapping compared with the International Prophylaxis Study Group (IPSG) structural MRI scores of ankle cartilage in boys with hemophilia receiving prophylaxis. Methods Eight boys with hemophilia A (median age, 13; range, 9-17 years), 7 age- and sex-matched healthy boys (controls, median age, 15; range, 7-16 years). A multiecho spin-echo T2-weighted MRI sequence at 3.0T was used to obtain T2 maps of cartilage of boys with hemophilia and controls. Structural joint status was evaluated using the IPSG MRI score. Results T2 relaxation times of ankle cartilage increased significantly over time in both persons with hemophilia and controls (P = .002 and P = .00009, respectively). Changes in T2 relaxation time strongly correlated with changes in IPSG cartilage scores (rs = 0.93 to rs = 0.78 [P = .0007 to P = .023]), but not with changes in age (P = .304 to P = .840). Responsiveness of T2 relaxation times were higher than that of IPSG cartilage scores, with standardized response means >1.4 for T2 mapping in all regions-of-interest compared with 0.84 for IPSG cartilage scores. Baseline T2 relaxation time strongly correlated with timepoint 2 IPSG cartilage score (rs = 0.93 to rs = 0.82 [P = .001 to P = .012]) and T2 relaxation time (rs = 0.98 to rs = 0.88 [P = .00003 to P = .004]) changes in most regions-of-interest. Conclusion T2 mapping shows sensitivity to biochemical changes in cartilage prior to detectable damage using conventional MRI, offering potential for early detection of bleed-related cartilage damage in boys with hemophilia.

Abstract
Botulinum neurotoxin (BoNT), a product of Clostridium botulinum, reversibly inhibits the presynaptic release of the neurotransmitter acetylcholine at the neuromuscular junction. In addition, BoNT blocks the transmission of other substances involved in pain perception and, together with a soft-tissue anti-inflammatory effect, may play a role in analgesia. When first-line treatment fails, second-line therapies might include BoNT. Studies on chronic and recurrent pain using different mechanisms offer heterogenous results that must be validated and standardized. Plantar fasciitis, severe knee osteoarthritis, painful knee and hip arthroplasty, antalgic muscular contractures, and neuropathic and myofascial pain syndromes may benefit from the administration of BoNT. Research on this topic has revealed the main musculoskeletal conditions that can benefit from BoNT, stressing the effects, modalities of administration, doses, and schedule.

Abstract
OBJECTIVE This study investigated the effects of physical therapy, including exercise, manual therapy, and physical agent modality, on joints, muscle strength, and mobility of patients with hemophilia. METHODS PubMed, Embase, MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, and Scopus were searched from inception to September 10, 2022. Randomized controlled trials comparing pain, range of motion, and health of joints, as well as muscle strength and mobility (timed up and go test) between physical therapy and control groups were included. RESULTS Fifteen randomized controlled trials with 595 male patients with hemophilia were included. In comparisons between physical therapy and control groups, physical therapy significantly reduced joint pain (standardized mean difference = -0.87; 95% confidence interval, -1.14 to -0.60), increased joint range of motion (standardized mean difference = 0.24; 95% confidence interval, 0.14-0.35), enhanced joint health (standardized mean difference = -1.08; 95% confidence interval, -1.38 to -0.78), improved muscle strength (standardized mean difference = 1.42; 95% confidence interval, 1.16-1.69), and timed up and go test performance (standardized mean difference = -1.25; 95% confidence interval, -1.89 to -0.60). The comparisons demonstrate moderate to high evidentiary quality grades. CONCLUSIONS Physical therapy is effective in reducing pain, increasing joint range of motion, enhancing joint health, as well as improving muscle strength and mobility in patients with hemophilia.

Abstract
BACKGROUND Evidence on bleeding rates in people with congenital haemophilia A (PwcHA) without inhibitors on factor VIII (FVIII) replacement products is inconsistent. AIM This systematic literature review assessed bleeding outcomes in PwcHA using FVIII-containing products as prophylactic treatment. METHODS A search was conducted using the bibliographic databases Medline, Embase and Cochrane Central Register of Controlled Trials on the Ovid platform. The search involved a bibliographic review of clinical trial studies, routine clinical care studies and registries and a search of ClinicalTrials.gov, EU Clinical Trials Register and conference abstracts. RESULTS The search yielded 5548 citations. A total of 58 publications were included for analysis. In 48 interventional studies, the pooled estimated mean (95% confidence interval [CI]) annualized bleeding rate (ABR), annualized joint bleeding rate (AJBR) and proportion of participants with zero bleeding events were 3.4 (3.0-3.7), 2.0 (1.6-2.5), and 38.5% (33.1-43.9), respectively. In 10 observational studies, the pooled estimated mean (95% CI) ABR, AJBR and proportion of participants with zero bleeding events were 4.8 (4.0-5.5), 2.6 (2.1-3.2), and 21.8% (19.9-47.5), respectively. A large variation in mean effect size for ABR, AJBR and zero bleeding event data across cohorts and cohort types was observed. Funnel plots indicated potential reporting bias for publications incorporating ABR and AJBR data across both interventional and observational studies. CONCLUSION This meta-analysis shows that PwcHA without inhibitors still have bleeds despite FVIII prophylaxis. Improved standardization on capturing and reporting bleeding outcomes is needed so that effective comparisons between treatments can be made.

Abstract
Haemophilia A (HA) and haemophilia B (HB) are X-linked inherited bleeding disorders caused by the absence or deficiency of coagulation factors VIII (FVIII) and IX (FIX), respectively. Recent advances in the development of effective treatments for haemophilia have led to a significant increase in life expectancy. As a result, the incidence of some comorbidities, including fragility fractures, has increased in people with haemophilia (PWH). The aim of our research was to perform a review of the literature investigating the pathogenesis and multidisciplinary management of fractures in PWH. The PubMed, Scopus and Cochrane Library databases were searched to identify original research articles, meta-analyses, and scientific reviews on fragility fractures in PWH. The mechanism underlying bone loss in PWH is multifactorial and includes recurrent joint bleeding, reduced physical activity with consequent reduction in mechanical load, nutritional deficiencies (particularly vitamin D), and FVIII and FIX deficiency. Pharmacological treatment of fractures in PWH includes antiresorptive, anabolic and dual action drugs. When conservative management is not possible, surgery is the preferred option, particularly in severe arthropathy, and rehabilitation is a key component in restoring function and maintaining mobility. Appropriate multidisciplinary fracture management and an adapted and tailored rehabilitation pathway are essential to improve the quality of life of PWH and prevent long-term complications. Further clinical trials are needed to improve the management of fractures in PWH.

[PMID: 37538501 PMCID: PMC10394546 DOI: 10.1016/j.rpth.2023.100195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 04/05/2023] [Accepted: 04/29/2023] [Indexed: 08/05/2023] Open
Abstract
Background Extended half-life factor IX (FIX) products have revolutionized prophylactic treatment for patients with hemophilia B as patients maintain protective FIX levels with minimal occurrence of spontaneous bleeding. rIX-FP is an extended half-life FIX product that allows prolonged dosing intervals. Objectives To assess individualized and prolonged prophylactic dosing interval up to 21 days in adult patients (≥18 years) with hemophilia B in the rIX-FP clinical trial program. Methods Patients who were included in the PROLONG-9FP phase III study or who received rIX-FP during surgery could continue into an extension study for long-term assessment. Patients began 7-day prophylaxis with rIX-FP, and after 6 months, they could extend dosing intervals to every 14 days. In the extension study, adult patients could switch to a 21-day regimen if well-controlled on a 14-day regimen. Results Eleven patients transitioned from a 7-day prophylaxis regimen to a 14-day regimen and finally to a 21-day regimen, 5 of whom were treated on demand at enrollment. Patients who switched to the 21-day regimen had a median annualized spontaneous bleeding rate of 0.0 across all regimens. The median observed FIX activity remained >5 IU/dL until day 21 after a single 100-IU/kg dose of rIX-FP. After 6 months on the 21-day regimen, 2 patients switched back to a 14-day regimen. No inhibitors, anaphylactic reactions, or thromboembolic events occurred. Conclusion Patients who are well controlled on a once-weekly regimen might extend their treatment interval to 14 days, and in adult patients, further extension to up to 21 days (100 IU/kg) may be considered.

Abstract
BACKGROUND This study retrospectively compared annualized billed bleed rates (ABRb) in people with hemophilia A (PwHA) without inhibitors who switched from factor VIII (FVIII) prophylaxis to emicizumab. RESEARCH DESIGN AND METHODS A real-world comparison study was performed on the effect of switching from FVIII to emicizumab prophylaxis in male, non-inhibitor patients on ABRb using an all-payer claims database (APCD) dataset from 1 January 2014, to 31 March 2021. The identification period was from 1 November 2017, to 30 September 2020. RESULTS One hundred and thirty-one patients were included with a total of 82 and 45 bleeds in the pre- and post-switch periods, respectively. The average follow-up period pre-switch was 978.37 days (SD 555.03), whereas the average follow-up period post-switch was 522.26 days (SD 191.36). No significant differences in mean ABRb were observed pre-/post-switch (0.25 and 0.20, respectively; P = 0.4456). CONCLUSIONS The results of this study demonstrate no significant reduction in ABRb, suggesting that switching from FVIII to emicizumab may not deliver incremental benefits to PwHA receiving prophylactic care.

Abstract
Surgical management of knee synovitis secondary to mild haemophilia, without any significant previous medical history and an adverse family history of haematological disorders, is arduous. Due to its rare occurrence, the diagnosis is often delayed or sometimes missed, leading to the grave and often lethal consequences in intraoperative and postoperative periods. Hardly isolated knee arthropathy due to mild haemophilia has been reported in the available literature. In this report, we present the management of a case of a 16-year-old male with isolated knee synovitis with undiagnosed mild haemophilia, who came to us with the first episode of knee bleeding. We elucidate the signs and symptoms, investigations, surgical management, and difficulties faced, especially during the postoperative period. This case report is presented to enhance awareness of the existence of this disorder and its management to prevent postoperative complications.

Abstract
BACKGROUND Haemophilic arthropathy is one of the main causes of morbidity in people with haemophilia (PWH), inducing pain and reduced functionality. Therefore, PWH are complex patients and must be approached from a multidisciplinary perspective. OBJECTIVES To evaluate the effectiveness of a therapeutic exercise and cognitive-behavioural therapy (CBT) combined protocol on functionality, pain, and joint health of PWH, arthropathy and chronic pain. Treatment satisfaction was also evaluated. METHODS A single-blinded clinical trial with 21 PWH in prophylactic regimen was carried out. Participants were divided into an experimental group (EG, n = 11) and a control group (CG, n = 10). The EG underwent a 4-month programme of home-based therapeutic exercise plus CBT, whilst CG performed their daily activities. Patients were evaluated at baseline, post-intervention and after 12 additional weeks. Measures of functionality (Haemophilia Activities List, Timed Up and Go Test, 2-Minutes-Walking-Test and Sit-to-Stand Test), pain (PainDETECT and Visual Analogue Scale) and joint health (Haemophilia Joint Health Score) were taken. Related dimensions of the A36 Haemophilia Quality of Life Questionnaire were calculated. Effects were calculated using a two-factor ANOVA. RESULTS The EG showed significant improvements in function (p < .001), pain (p < .001), joint damage (p = .006), and satisfaction with the treatment (p = .006) dimensions of the A36 Haemophilia Quality of Life Questionnaire, as well as in pain measured with the Visual Analogue Scale (p = .008) and PainDETECT (p = .035). CONCLUSIONS The combined physiotherapy and CBT protocol showed a partial improvement in functionality, pain and joint health of PWH, arthropathy and chronic pain. In addition, participants were satisfied with the treatment.

[PMID: 36908770 PMCID: PMC9992752 DOI: 10.1016/j.rpth.2023.100077] [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: 08/18/2022] [Revised: 12/05/2022] [Accepted: 12/29/2022] [Indexed: 02/09/2023] Open
Abstract
Background Across the HAVEN clinical trial program, the efficacy of emicizumab has been demonstrated in children, adolescents, and adults with hemophilia A, with or without factor VIII inhibitors. After the 4-week loading dose period, emicizumab concentrations are expected to remain at levels that provide bleed protection throughout the entire dosing interval, regardless of the chosen maintenance dosing regimen, ie, weekly, every 2 weeks, or every 4 weeks. Objectives The objective of this study was to examine the timing of treated bleeds within the dosing intervals for emicizumab administered during the HAVEN 1 to 4 studies. Methods In this post hoc analysis, we pooled data from all the participants of the HAVEN 1 to 4 studies and analyzed the timing of treated bleeds in relation to the emicizumab dose. Results A total of 392 participants were included in this analysis, with a median (range) age of 28.0 years (1.1-77.0 years). Target joints were identified in 237 of 392 (60.5%) participants before the study entry. Overall, 211 of 392 (53.8%) participants experienced 907 treated bleeding events. The total mean (SD) annualized bleeding rate across the 4 studies was 1.6 (5.9). There was no evidence that bleeding events clustered on any 1 particular day in any dosing schedule from HAVEN 1 to 4 (P > .05 for all 3 treatment regimens). Conclusion Data from the HAVEN 1 to 4 trials show consistent bleed prevention within the dosing interval, regardless of the dosing regimen chosen. These findings provide further evidence of the sustained efficacy of emicizumab across all approved dosing regimens to reduce bleeding in people with hemophilia A.

Abstract
INTRODUCTION Emicizumab promotes effective haemostasis in people with haemophilia A (PwHA). It is indicated for routine prophylaxis of bleeding episodes in PwHA with or without factor (F)VIII inhibitors. AIM To investigate the effect of emicizumab dose up-titration in PwHA with suboptimal bleeding control. METHODS Data from seven completed or ongoing phase III studies were pooled. Pharmacokinetics, pharmacodynamics and bleeding events were evaluated before and after dose up-titration. Adverse events (AEs) were compared between PwHA with and without dose up-titration. RESULTS Of 675 PwHA evaluable for the analysis, 24 (3.6%) had their maintenance dose up-titrated to 3 mg/kg once weekly (QW). Two participants had neutralising antibodies (nAbs) associated with decreased emicizumab exposure, and dose increase did not compensate for the effect of nAbs. In the other 22 participants, mean emicizumab steady-state trough concentrations increased from 44.0 to 86.2 μg/mL after up-titration. The median (interquartile range [IQR]) efficacy period prior to up-titration was 24.6 (24.0-32.0) weeks. The model-based annualised bleed rate for 'treated bleeds' and 'all bleeds' decreased by 70.2% and 72.9%, respectively, after a median (IQR) follow-up of 97.1 (48.4-123.3) weeks in the up-titration period. Incidences of injection-site reactions and serious AEs were higher in PwHA with up-titration; however, this was already observed in these participants before the dose up-titration. Overall, the safety profile appeared similar between PwHA with and without up-titration. CONCLUSION The dose up-titration to 3 mg/kg QW was well tolerated. Bleed control improved in most participants whose bleeding tendency was inadequately controlled during clinical trials.

Abstract
BACKGROUND Patients with haemophilic arthropathy suffer chronic pain that affects and restricts their quality of life. Visualization of movement through immersive virtual reality is used for pain management. AIM To evaluate the efficacy of 180-degree immersive VR motion visualization therapy in patients with haemophilic ankle arthropathy. METHODS Prospective, multicentre pilot study. Fifteen adult patients with bilateral haemophilic ankle arthropathy were recruited (mean age: 42.73 ± 12.36 years). The intervention lasted 4 weeks, with daily home sessions of 180-degree immersive motion visualization. The patients were given virtual reality glasses to use with their smartphones. From the YouTube mobile app® they accessed the recorded video with access from the He-Mirror App®. The study variables were joint state (Haemophilia Joint Health Score), pressure pain threshold (pressure algometer), muscle strength (dynamometry) and range of motion (goniometry). Three evaluations were performed: at baseline (T0), after the intervention (T1) and at the end of a 16-week follow-up period (T2). RESULTS No patient developed ankle hemarthrosis during the experimental phase. In the repeated measures analysis we found statistically significant differences in joint state (F = 51.38; η2 p = .63), pressure pain threshold of the lateral malleolus (F = 12.34; η2 p = .29) and range of motion (F = 11.7; η2 p = .28). CONCLUSIONS Therapy using immersive motion visualization does not cause hemarthrosis. This intervention can improve joint condition, pressure pain threshold and range of motion in patients with ankle arthropathy. Changes greater than the MDC were reported in more than 40% of patients for the variables pressure pain threshold, anterior tibialis strength and range of motion, which were considered clinically relevant.

Abstract
Joint arthropathies often require continuous monitoring of the joint condition, typically performed using magnetic resonance (MR) or ultrasound (US) imaging. US imaging is often the preferred screening or diagnostic tool as it is fast and inexpensive. However, conventional 2-D US has limited capability to compare imaging results between examinations because of its operator dependence and challenges related to repeat imaging in the same location and orientation. Comparison between several imaging sessions is crucial to assess the interval progression of joint conditions. We propose a novel 3-D US scanner for ankle joint assessment that can partially overcome these issues by enabling 3-D imaging. Here, we (i) present the design of the 3-D US ankle scanner system, (ii) validate the geometric reconstruction accuracy of the system, (iii) provide preliminary images of healthy volunteer ankles and (iv) compare 3-D US imaging results with MR imaging. The 3-D ankle scanner consists of a tub filled with water, a linear US probe attached to the wall of the tub and a motorized unit that rotates the US probe 360° around the center of the tub. As the probe rotates, a 3-D US image is formed of the ankle of the patient positioned in the middle of the tub. US probe height, angle and distance from the tub center can be adjusted. The reconstruction accuracy of the system was validated in each of the coordinate directions at different probe angles using two test phantoms. A phantom consisting of numerous Ø200-µm nylon threads with known spacing and a metal rod with machined grooves was used for validation in the horizontal and vertical directions, respectively. The volumetric reconstruction accuracy validation was performed by imaging an agar phantom with two embedded spheres of known volumes and comparing the segmented sphere volume and surface area with the expected. Three-dimensional US and MR images of both ankles of five healthy volunteers were acquired. Distal tibia and proximal talus were segmented in both imaging modalities and the surfaces of these segmentations were compared using the 95% Hausdorff and mean surface distances. The observed mean linear measurement error in all the coordinate directions and over several probe angles was 2.98%. The mean measured volumetric measurement error was 3.45%. The volunteer study revealed useful features for joint assessment present in the 3-D ankle scanner images, such as joint spacing, distal tibia and proximal talus. The mean 95% Hausdorff and mean surface distances between segmentations in 3-D US and MR images were 5.68 ± 0.83 and 2.01 ± 0.30 mm, respectively. In this proof-of-concept study, the 3-D US ankle scanner enabled visualization of the ankle joint features that are useful for joint assessment.

Abstract
Haemophilia treatment has seen great advances in recent years with an accompanied reduced risk of physical activity (PA) related bleeds. Based on its known health benefits, people with haemophilia (PWH) are currently encouraged to regularly engage in PA. However, this may not always translate to increased levels of PA. In this narrative review we aim to provide a brief overview of what is currently understood regarding PA levels and influences for the three broad age groups of children and adolescents, adults and older adults. We also provide recommendations for members of the haemophilia team on important aspects related to promotion of PA in their clinical practice. We highlight that PA behaviour is multifactorial and that many PWH still have limited access to adequate care. Whilst some still face unique challenges to being more physically active, overall, the barriers and facilitators to activity are very similar to that of the general population.

INTRODUCTION Befovacimab (formerly BAY 1093884) is a fully human monoclonal antibody able to bind to tissue factor pathway inhibitor (TFPI) and developed as a non-replacement therapy for individuals with haemophilia A/B, with or without inhibitors. AIM To assess the safety of multiple escalating doses of befovacimab in individuals with severe haemophilia A/B with or without inhibitors. METHODS In this non-randomised, open-label Phase 2 study (NCT03597022), adult males with <1% factor VIII or <2% factor IX and ≥4 bleeds in the previous six months were enrolled in three dose cohorts (100/225/400 mg). Participants received befovacimab subcutaneously once weekly. The primary endpoint was safety; secondary endpoints included annualised bleeding rate (ABR) and pharmacokinetics/pharmacodynamics (PK/PD) of befovacimab. RESULTS A total of 24 participants (n = 8 in each dose cohort) were treated for 2-47 weeks. Patients treated with 100 mg and 225 mg doses of befovacimab demonstrated improved bleeding control compared with pre-study bleeding rates, with a dose-dependent effect. Dosing was suspended and the study prematurely terminated following three drug-related thrombotic serious adverse events (SAEs): two at the 225 mg dose and one at the 400 mg dose. These occurred in the absence of bleeding episodes or concomitant use of replacement/bypass therapies. No laboratory abnormalities were observed, and PK/PD data did not show correlation between SAE occurrence and levels of circulating befovacimab or free TFPI. CONCLUSION Despite favourable initial results from preclinical and clinical studies, a positive safety profile of befovacimab was not confirmed. The lack of SAE-related laboratory abnormalities or differentiating PK/PD characteristics in participants experiencing SAEs raises concerns about the predictability of thrombosis following befovacimab treatment and emphasises the need for further investigation into the therapeutic window of anti-TFPI treatment.

Abstract
INTRODUCTION A complete functional assessment is essential to measure health status and treatment effects in patients with haemophilia. The Patient-Specific Functional Scale (PSFS) is a reliable, valid, simple and quick scale that measures physical function in patients with musculoskeletal disorders. However, the reliability and validity of the PSFS have not been evaluated in patients with haemophilia. AIM The aim of this study was to validate the Patient-Specific Functional Scale in patients with haemophilia. METHODS Twenty-eight patients with haemophilia participated in the study. They completed the PSFS and the Haemophilia Activity List (HAL) scales by telephone during an initial session, and then repeated the assessment in a follow-up session 1 week apart. Reliability was analysed by the internal correlation coefficient (ICC), the standard error of measurement (SEM) and the smallest detectable change (SDC). The concurrent validity of the PSFS was determined by correlating the initial score of the PSFS scale to the initial score of the HAL scale. Correlations were calculated by means of scatter plots and Pearson product-moment r correlation coefficient. RESULTS ICC and SEM values showed excellent reliability for the PSFS scale, with a SDC of 1. A significant moderate correlation was found between the results of the PSFS and the HAL (r = .57, P < .001). CONCLUSION The PSFS is a reliable and valid scale to measure the functionality of people with haemophilia.

Abstract
AIMS Ankle arthropathy commonly affects persons with haemophilia (PWH). Joint damage causes loss of movement, pain and reduced function. Current treatments are limited. Viscosupplementation has been used to treat other patient groups with joint damage. Viscosupplements serve to augment or act as a substitute for synovial fluid and may ameliorate the effects of cartilage loss by cushioning joints and reducing pain. This study evaluated intra-articular Ostenil Plus™ (HA) for ankle arthropathy in PWH. Reduction in pain was the primary outcome. METHODS A single centre open label pilot study. PWH and significant ankle arthropathy, according to MRI scores, were recruited. Participants received intra-articular HA injections at baseline and 6 months. Follow up assessments were completed three-monthly for 1 year. Pain was assessed by the Visual Analogue Scale (VAS). Participant perceptions of overall changes to pain, function and quality of life were sought. RESULTS Twenty-four participants were recruited, three withdrew. Twenty-six joints were injected. Twenty participants had severe haemophilia. Mean age 35 years. Participants reported significant reduction in pain over the study. VAS baseline: 5.62; 6 month 3.92; 12-month 3.42, P < .0001. Joint function improved together with ankle HJHS. No change was seen for EQ-5D-5L. Sixteen participants reported reductions in ankle pain and stiffness and greater confidence in undertaking physical activities. No significant adverse reactions were reported. CONCLUSION Ostenil Plus™ treatment improves pain, function and patient perception of functional ability in PWH and ankle arthropathy. This study supports the use of HA as a safe treatment in PWH.

Abstract
INTRODUCTION Persons with haemophilia A (PwHA) commonly experience regular bleeding into joints, which may result in joint damage and complications such as degenerative arthritis. Emicizumab has previously demonstrated efficacy in reducing the occurrence of joint bleeds and target joints, along with having a favourable safety profile; however, data on the long-term effects on joint health are lacking. The AOZORA study will evaluate the long-term safety and joint health of paediatric PwHA without factor (F)VIII inhibitors taking emicizumab; here, we report the details of the study protocol and baseline data. METHODS AND ANALYSIS AOZORA is a multicentre, open-label, phase IV clinical study in Japan that aims to enrol approximately 30 PwHA aged <12 years without FVIII inhibitors. The primary endpoints include a long-term safety evaluation of adverse events, laboratory test abnormalities and FVIII inhibitor development; and a long-term joint health assessment using MRI and the Hemophilia Joint Health Score. Exploratory endpoints include characterising participants' physical activities and the number of activity-related bleeds requiring coagulation factor treatment. Currently, 30 participants have been enrolled, including 20 emicizumab-naïve participants and 10 who transferred from HOHOEMI, a previous study in paediatric PwHA. ETHICS AND DISSEMINATION The AOZORA study was approved by the Institutional Review Boards of Nara Medical University and the St Marianna University Group. The study will be conducted in compliance with the Declaration of Helsinki, the standards stipulated in paragraph 3 of Article 14 and Article 80-2 of the Pharmaceuticals, Medical Devices and Other Therapeutic Products Act, the Ministerial Ordinance on Good Clinical Practice and the Ministerial Ordinance on Good Post-marketing Study Practice. Data will be published in peer-reviewed journals and presented at Global congresses. TRIAL REGISTRATION NUMBER JapicCTI-194701.

Abstract
Hemophilia is the most common X-linked bleeding diathesis caused by the genetic deficiency of coagulation factors VIII or IX. Despite treatment advances and improvements in clinical management to prevent bleeding, management of acute and chronic pain remains to be established. Repeated bleeding of the joints leads to arthropathy, causing pain in hemophilia. However, mechanisms underlying the pathogenesis of pain in hemophilia remain underexamined. Herein, we describe the novel perspectives on the role for oxidative stress in the periphery and the central nervous system that may contribute to pain in hemophilia. Specifically, we cross examine preclinical and clinical studies that address the contribution of oxidative stress in hemophilia and related diseases that affect synovial tissue to induce acute and potentially chronic pain. This understanding would help provide potential treatable targets using antioxidants to ameliorate pain in hemophilia.

Abstract
Background: This study aims to identify factors affecting health-related quality of life (HRQoL) in Chinese patients with hemophilia in Hong Kong, and to examine the association between treatment adherence and HRQoL outcomes. Methods: Patients with hemophilia A or B from a non-governmental organization reported their HRQoL and treatment adherence to prophylactic therapy using validated tools. Univariate tests and multivariable regression analysis were used to compare differences in outcomes across clinically relevant subgroups. Results: Fifty-six patients were recruited (mean age 30.4 [17.4] years; majority hemophilia A: 75%; moderate-to-severe severity: 88%). Patients who received prophylactic treatment reported fewer work/school problems (25.8 [18.9] versus 51.5 [26.3]; p = 0.001) than those who received on-demand therapy. The multivariable model showed that older age (B = 0.42, 95% CI = 0.093−0.75) and living in public housing (B = 10.24, 95% CI = 0.70−19.77) were associated with worse HRQoL. Older age was associated with treatment non-adherence (r = 0.66, p < 0.0001). Patients with poor adherence tended to report worse functioning in sports/leisure (r = 0.31, p = 0.033). Conclusions: Our results suggest that patients who were older, had lower education attainment and received on-demand treatment had poorer perception of their health. Improving adherence may lead to better HRQoL. Future work includes evaluating the occupational needs prospectively in this population.

Abstract
Background Prophylactic treatment is the gold standard in the treatment of patients with haemophilia. Prophylaxis with extended half‐life (EHL) treatment has shown long‐term safety and efficacy in patients with haemophilia. Aim To evaluate the efficacy of prophylaxis with EHL treatment in the frequency of haemarthrosis and musculoskeletal health in adult patients with severe haemophilia A. Methods Prospective cohort study. Forty‐six patients with severe haemophilia A were recruited. The frequency of haemarthrosis (self‐reports), joint condition (Haemophilia Joint Health Score), pain intensity (visual analogue scale), range of motion (goniometry), and strength (dynamometry) and muscle activation (surface electromyography) were evaluated. Three assessments were carried out: at baseline (T0), at 6 months (T1) and at 12 months following treatment (T2). Results There were significant changes in the within‐subject effect in the frequency of haemarthrosis in elbow (F(1.05;96.20) = 3.95; P < .001) and knee (F(1.73;157.99) = 9.96; P < .001). Significant within‐subject effect in elbow pain intensity (F(2;182) = 63.51; P < .001) was found. The mean values of the frequency haemarthrosis in elbow (from .66±1.01 to .04±.20) and knees (from .55±.68 to .33±.53) decrease after the period study. The intensity of elbow pain and (from 3.08±1.69 to 2.67±1.73), decrease after the 12‐month follow‐up period. Conclusions Prophylaxis with extended half‐life treatment reduces the frequency of haemarthrosis in elbow and knee in adult patients with haemophilia. EHL treatment reduces the intensity of elbow pain in patients with haemophilic arthropathy.

Abstract
Haemophilia B is a rare X-linked genetic deficiency of coagulation factor IX (FIX) that, if untreated, can cause recurrent and disabling bleeding, potentially leading to severe arthropathy and/or life-threatening haemorrhage. Recent decades have brought significant improvements in haemophilia B management, including the advent of recombinant FIX and extended half-life FIX. This therapeutic landscape continues to evolve with several non-factor replacement therapies and gene therapies under investigation. Given the rarity of haemophilia B, the evidence base and clinical experience on which to establish clinical guidelines are relatively sparse and are further challenged by features that are distinct from haemophilia A, precluding extrapolation of existing haemophilia A guidelines. Due to the paucity of formal haemophilia B-specific clinical guidance, an international Author Group was convened to develop a clinical practice framework. The group comprised 15 haematology specialists from Europe, Australia, Japan, Latin America and North America, covering adult and paediatric haematology, laboratory medicine and biomedical science. A hybrid approach combining a systematic review of haemophilia B literature with discussion of clinical experience utilized a modified Delphi format to develop a comprehensive set of clinical recommendations. This approach resulted in 29 recommendations for the clinical management of haemophilia B across five topics, including product treatment choice, therapeutic agent laboratory monitoring, pharmacokinetics considerations, inhibitor management and preparing for gene therapy. It is anticipated that this clinical practice framework will complement existing guidelines in the management of people with haemophilia B in routine clinical practice and could be adapted and applied across different regions and countries.

Abstract
Abstract
Background
Hemophilic arthropathy results in pain, deformity, and disability with severe impairments, activity limitation, and thus productivity loss. Also patterns of treatment interfere with patients’ life, so the quality of life should be assessed when evaluating treatment. The aim of this work was to assess the quality of life of children with hemophilic arthropathy and its relation to clinical joint health.
Results
The study was carried out on fifty boys with hemophilic arthropathy. All patients were subjected to thorough local clinical assessment of the most affected and/or target joint using Hemophilia Joint Health Score (HJHS 2.1) and assessment of quality of life using Haemo quality of life (Haemo-Qol) questionnaire children and parent versions. Among the fifty hemophilic patients, 36 (72%) patients were hemophilia A and 14 (28 %) patients were hemophilia B. The age at first hemarthrosis ranged from 1 to 8 years with a mean of 2.40±1.78. While the number of joints affected in the studied patients ranged from 2 to 13 joints with a mean of 7±3.25. As regards the severity, 23 patients (46%) had severe, and 27 (54%) had moderate hemophilia. Forty four (88%) patients had different degrees of anemia. There was significant correlation between child Haemo-QoL with degree of anemia (r = 0.291, P = 0.040), mainly with view and school dimensions. There were significant correlations between child and parent Haemo-QoL and HJHS with each of the following: factor activity level, duration of the disease, duration of joint disease, number of bleeding attacks last year, and number of joints affected. Synovectomy was done for 5 (10%) patients. The total child Haemo-QoL score was statistically significantly lower after the intervention (P=0.043), with a significant improvement in physical health, feeling, view, family, school and sports, treatment, and dealing dimensions. In the current study, there were significant positive correlations between child and parent Haemo-QoL and HJHS scores.
Conclusions
The quality of life in patients with hemophilic arthropathy was influenced by the joint health, factor activity level, disease duration, number of bleeding attacks, number of joints affected (during life), duration of joint disease, and presence of hepatitis C virus.

Gait Posture 2022; 93:26-31. [PMID: 35051714 DOI: 10.1016/j.gaitpost.2022.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 12/09/2021] [Accepted: 01/12/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Patients with severe haemophilia suffer from bleeding-related joint changes in which the ankle joint is most frequently affected. In the resulting gait changes, the forefoot is involved by reducing the foot pressure. However, it is unclear which changes in foot pressure are present in the individual's foot zones. RESEARCH QUESTION The aim of the study was to determine whether compensation mechanisms are present in the foot zones regarding the peak pressure under dynamic conditions and to identify possible underlying mechanisms for gait changes. METHODS In a controlled cross-sectional study, a pedobarography was performed during gait with a standardized speed (3 km/h) in patients with haemophilia (PwH;n = 40) and healthy controls (Con;n = 40). Pressure pain thresholds (PPT) were detected, and Haemophilia Joint Health Score (HJHS) was performed to determine the current joint status. RESULTS PwH showed a decreased peak pressure in metatarsals II-IV and heel compared to Con. Patients with major-affected ankle joints (determined with the HJHS) showed a decreased single-step length, stride-length and stride-time. Accordingly, the cadence was increased by 10 ± 11 steps/min in PwH compared to Con. Furthermore, PwH showed decreased ankle range of motion (ROM) in HJHS and an altered pain perception due to reduced PPT. SIGNIFICANCE PwH showed a changed gait pattern in peak pressure compared to Con. A restricted rolling behavior, which might be caused by movement restrictions and pain sensation, leads to reduced pressure in the center forefoot, resulting in a shorter stride-length. Future therapies should focus on maintaining joint mobility for better rolling behavior and improving ankle joints' stability to achieve a balanced load between the midfoot, heel, and forefoot. The use of insoles adapted to our data, based on group differences between PwH and Con, could be supportive in this case.

Abstract
Gastrointestinal bleeding (GIB) is serious, intractable, and potentially life-threatening condition. There is considerable heterogeneity in GIB phenotypes among congenital bleeding disorders (CBDs), making GIB difficult to manage. Although GIB is rarely encountered in CBDs, its severity in some patients makes the need for a comprehensive and precise assessment of underlying factors and management approaches imperative. Initial evaluation of GIB begins with assessment of hematological status; GIB should be ruled out in patients with chronic anemia, and in presentations that include hematemesis, hematochezia, or melena. High-risk patients with recurrent GIB require urgent interventions such as replacement therapy for treatment of coagulation factor deficiency (CFD). However, the best management strategy for CFD-related bleeding remains controversial. While several investigations have identified CBDs as potential risk factors for GIB, research has focused on assessing the risks for individual factor deficiencies and other CBDs. This review highlights recent findings on the prevalence, management strategies, and alternative therapies of GIB related to CFDs, and platelet disorders.

Arvanitakis A, Holme PA, Berntorp E, Astermark J. Clinical outcome and adherence rate in Scandinavian patients with intermediate-intensity prophylaxis before and after the switch of standard half-life FVIII products to BAY 81-8973. Haemophilia 2022; 28:223-229. [PMID: 35005818 DOI: 10.1111/hae.14489] [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: 09/16/2021] [Revised: 12/20/2021] [Accepted: 12/29/2021] [Indexed: 01/19/2023]
Abstract
INTRODUCTION Treatment optimization in haemophilia A can be achieved by choice of FVIII product and knowledge of pharmacokinetics (PK), phenotype and adherence. A favourable PK profile of BAY 81-8973 (octocog alfa) (Kovaltry, Bayer AB) compared to other standard half-life (SHL) FVIII products has been suggested. AIM To evaluate whether the switch to BAY 81-8973, using the same dosing schedule, impact factor consumption and bleed rates, taking arthropathy and adherence into account METHODS: Forty patients on prophylaxis with SHL (median age 40.5 years) attending the haemophilia treatment centres in Malmö and Oslo were enrolled. The annualised bleeding rate (ABR) and joint bleeding rate (AJBR) before and after the switch to BAY 81-8973 was calculated. PK analyses were performed with WAPPS-Hemo. Joint health status and treatment adherence were assessed. RESULTS The median ABR and AJBR was 0 before and after the switch, at both centres. The median yearly factor consumption was 3,345 IU/Kg/year in the entire study group corresponding to intermediate-intensity prophylaxis in most patients and with significantly more used in Malmö (3,862 IU/Kg/year), compared to Oslo (2,337 IU/Kg/year) (P .006). There was no correlation between arthropathy and bleeding. The median BAY 81-8973 t½ was 20 h (range 7.5-29 h), with significant correlation to VWF levels, and 13.4 h after exclusion of VWF outliers. Adherence to treatment was 97%. CONCLUSIONS Concentrate switch, using mainly intermediate-intensity regimens with high adherence rates, preserves excellent prophylaxis outcome using standard half-life FVIII products, indicating the value of individualized prophylaxis and close follow-up.
