Association of patient, treatment and disease characteristics with patient-reported outcomes: Results of the ECHO Registry.

INTRODUCTION: Patient-reported outcomes (PROs) in people living with haemophilia A (PLWHA) are often under-reported. Investigating PROs from a single study with a diverse population of PLWHA is valuable, irrespective of FVIII product or regimen. AIM: To report available data from the Expanding Communications on Haemophilia A Outcomes (ECHO) registry investigating the associations of patient, treatment and disease characteristics with PROs and clinical outcomes in PLWHA. METHODS: ECHO (NCT02396862), a prospective, multinational, observational registry, enrolled participants aged ≥16 years with moderate or severe haemophilia A using any product or treatment regimen. Data collection, including a variety of PRO questionnaires, was planned at baseline and annually for ≥2 years. Associations between PRO scores and patient, treatment and disease characteristics were determined by statistical analyses. RESULTS: ECHO was terminated early owing to logistical constraints. Baseline data were available from 269 PLWHA from Europe, the United States and Japan. Most participants received prophylactic treatment (76.2%), with those using extended-half-life products (10.0%) reporting higher treatment satisfaction. Older age and body weight >30 kg/m2 (>BMI) were associated with poorer joint health. Older age was associated with poorer physical functioning and work productivity. Health-related quality of life and pain interference also deteriorated with age and >BMI; >BMI also increased pain severity scores. CONCLUSION: ECHO captured a variety of disease characteristics, treatment patterns, PROs and clinical outcomes obtained in real-world practice with ≤1 year's follow-up. Older age, poorer joint health and >BMI adversely affected multiple aspects of participant well-being.

Cross-cultural assessment of the influence of the COVID-19 pandemic on the perceived mental health and medical experiences of persons with inherited bleeding disorders and their parents/guardians.

BACKGROUND: Objectives were to 1) assess COVID-19-associated medical and psychological challenges facing persons with inherited bleeding disorders (PIBD) and their parents/guardians (PG) in Germany, the US, and the UK; 2) describe similarities and differences among these countries; 3) identify needs and opportunities for intervention by patient advocacy organizations (PAGs). RESEARCH DESIGN & METHODS: A cross-sectional, international survey was conducted in three countries using validated psychometric instruments and investigator-developed items. RESULTS: Five hundred and four surveys were included. Significant differences between countries were found including experiences with medical care, specific thoughts, and concerns about COVID-19, anxiety, and other mental health measures, as well as resources used to cope with stress. Age, education, income, race, IBD diagnosis, PIBD vs. BD group, and gender had moderating effects on resources used. Communication with friends/relatives and use of PAG and HTCs as resources for information/coping decreased in all countries during the pandemic. CONCLUSIONS: There were similarities and differences between respondents across the country in the perceived impact of the pandemic, mental health scores, and strategies used to cope with stress.  Recommendations: strategies to increase PAG access for PIBD and their PG during pandemics and natural disasters, ongoing assessment and adaptation to provide supportive resources to specific patient subgroups.

Persons with inherited bleeding disorders (PIBD) and their parents faced many challenges during the COVID-19 pandemic. An online survey was conducted within three countries: Germany, the United States, and the United Kingdom to explore these challenges and address how patient advocacy organizations can better meet their needs. Areas explored included experiences with medical care, concerns, and thoughts expressed during the pandemic, and coping resources used before and during the pandemic. In addition, mental health issues were explored addressing anxiety, COVID-related fears, depression, and resilience. Differences were found regarding experiences with medical care, specific thoughts, and concerns about COVID-19, anxiety, and other mental health measures, as well as resources used to cope with stress. These results provide an opportunity for advocacy organizations for PIBD to develop appropriate assessment, adaptation, and education resources to help patients during pandemics and/or natural disasters in the future.

Gene Therapy in Hemophilia: A Transformational Patient Experience.

Hemophilia is a bleeding disorder caused by a single absent/defective gene and characterized by a lack of functional clotting factors. People with hemophilia may experience joint damage, pain, and psychological impairments, all of which could contribute to reduced health-related quality of life (HRQoL). The current standard of care is clotting factor replacement, which is associated with regular infusions; therefore, alternative treatments such as gene therapy (GT) are in development. GT involves the delivery of a functional copy of the clotting factor 8/9 gene by a single infusion into the patient's cells, enabling them to produce their own clotting factor VIII/IX. The impact of treatment on patients' HRQoL can be assessed using hemophilia-specific patient-reported outcome (PRO) measures. Since these measures were designed before the advent of GT, there is a need for updated individualized PRO measures. Patient groups and regulatory authorities emphasize the need for increased patient engagement when considering clinical trial design. Here, we provide patients' perspective on undergoing GT and discuss how to capture the patient voice when measuring the therapy's transformative impact.

The effect of a virtual child disease management programme on burden and social adjustment of caregivers of children with coagulation factor deficiencies.

INTRODUCTION: The use of virtual interventions is of interest to patients with chronic disease and healthcare professionals. This study aimed to determine the effect of virtual child disease management programme on burden and social adjustment of caregivers of children with coagulation factor deficiencies. Moreover, the effect of this intervention on children's acute pain and bleeds was assessed. METHODS: This clinical trial was conducted on 80 caregivers of children with coagulation factor deficiencies. The subjects were randomly assigned into the intervention and control groups. A comprehensive virtual child disease management programme was conducted for 8 weeks and caregiver' burden and their social adjustment were assessed with the HEMOCAB and social adjustment subscale of Bell Adjustment Inventory, respectively. Data were analysed using ANCOVA and Wilcoxon test. RESULTS: Before the intervention, both groups were similar regarding the caregivers' burden and social adjustment and children's acute pain and bleeds. However, a significant difference was observed between groups in concern to caregivers' burden (P < .001), women's and men's social adjustment (P = .001, P = .03), and children's acute pain and bleeds (P < .001) after the virtual disease management programme. CONCLUSION: This study showed that using a virtual child disease management programme reduced burden and improved social adjustment of caregivers of children with coagulation factor deficiencies. This intervention decreased frequencies of acute pain and bleeds in children. Therefore, using this effective intervention in clinical practice is warranted to decrease the caregivers' burden as well as acute pain and bleeds in children.

Efficacy and safety in patients with haemophilia A switching to octocog alfa (BAY 81-8973): Final results of the global real-world study, TAURUS.

OBJECTIVES: To report the final results of the 2-year TAURUS study, assessing weekly prophylaxis dosing regimens of octocog alfa (Kovaltry®/BAY 81-8973) used in standard clinical practice in patients with moderate-to-severe haemophilia A. METHODS: TAURUS (NCT02830477) is a phase 4, multinational, prospective, non-interventional, single-arm study in patients of any age with moderate or severe haemophilia A (≤5% factor [F]VIII activity). TAURUS was designed to primarily investigate weekly prophylaxis dosing regimens used in standard clinical practice. Annualised bleeding rates (ABRs), treatment satisfaction and adherence, and safety were also assessed. RESULTS: Of 302 patients included in the full analysis set, 84.4% (n = 255) maintained their octocog alfa prophylaxis baseline regimen throughout the study, with a majority of patients (76.5%, n = 231) on two times or three times weekly regimens at the end of the observation period (≥1-≤2 years). ABRs, treatment satisfaction, and adherence remained stable during the observation period. Octocog alfa was well tolerated and there were no new or unexpected adverse events. CONCLUSIONS: These data show that a smooth transition is observed when switching to octocog alfa from a previous FVIII treatment, with no safety issues and stable bleeding rates in a real-world setting of patients with moderate-to-severe haemophilia A.

The effect of emicizumab prophylaxis on long-term, self-reported physical health in persons with haemophilia A without factor VIII inhibitors in the HAVEN 3 and HAVEN 4 studies.

INTRODUCTION: Severe haemophilia A (HA) has a major impact on health-related quality of life (HRQoL). AIM: Assess the impact of emicizumab on HRQoL in persons with severe HA (PwHA) without factor VIII (FVIII) inhibitors in the phase 3 HAVEN 3 and 4 studies. METHODS: This pooled analysis examines the HRQoL of PwHA aged ≥ 18 years treated with emicizumab prophylaxis via Haemophilia-Specific Quality of Life Questionnaire for Adults (Haem-A-QoL) and EuroQoL 5-Dimensions 5-levels (EQ-5D-5L). In particular, changes from baseline in Haem-A-QoL 'Physical Health' (PH) domain and 'Total Score' (TS) are evaluated. RESULTS: Among 176 evaluable participants, 96 (55%) had received prior episodic treatment and 80 (45%) prophylaxis; 70% had ≥ 1 target joint and 51% had experienced ≥ 9 bleeds in the previous 24 weeks. Mean Haem-A-QoL PH and TS improved after emicizumab initiation. Mean (standard deviation) -12.0 (21.26)- and -8.6 (12.57)-point improvements were observed in PH and TS from baseline to Week 73; Week 73 scores were 27.9 (24.54) and 22.0 (14.38), respectively. Fifty-four percent of participants reported a clinically meaningful improvement in PH scores (≥ 10 points) by Week 73. Subgroups with poorer HRQoL prior to starting emicizumab (i.e. receiving episodic treatment, ≥ 9 bleeds, target joints) had the greatest improvements in PH scores, and corresponding reductions in missed workdays; change was not detected among those previously taking prophylaxis. No change over time was detected by the EQ-5D-5L questionnaire. CONCLUSIONS: Emicizumab prophylaxis in PwHA without FVIII inhibitors resulted in persistent and meaningful improvements in Haem-A-QoL PH and less work disruption than previous treatment.

[Impact of COVID-19 Pandemic on Medical Care of Patients with Inherited Bleeding Disorders]. / Auswirkungen der COVID-19 Pandemie auf die medizinische Versorgung von Patienten mit angeborenen Blutungsneigungen.

BACKGROUND AND OBJECTIVES: Chronic diseases, such as inherited bleeding disorders (IBD) are often associated with high costs of medical care. COVID-19 containment measures, including isolation and triage, led to restrictions in the health care of chronically ill patients. The aim of the present study was to investigate the effects of the COVID-19 pandemic on the health care of IBD patients. METHODS: In this multicentre cross-sectional study to evaluate the effects of COVID-19 on the mental health and quality of care of patients with inherited bleeding disorder, an ad hoc questionnaire was sent to 586 patients/parents of children with haemophilia A, B or von Willebrand syndrome type 3. In addition to demographic and clinical data, patients/parents of patients with inherited bleeding disorders were asked about their thoughts, concerns and experiences regarding their medical care during the COVID-19 pandemic. Differences between clinical subgroups were calculated. RESULTS: Significant differences were found between subgroups (severity, type of therapy, product class, comorbidities) with regard to the transmission of COVID-19 through plasma products, the effects of COVID-19 positive test results, fear of getting COVID-19, delayed drug supply and physiotherapy treatment. DISCUSSION: The medical care of patients with inherited bleeding disorders, who need a continuous supply of essential drugs, is a particular challenge in times of pandemics. Therefore, worries and fears of IBD patients should be taken seriously and innovative communication channels established to maintain therapy standards and quality of care.

Health-related quality of life and health status in adolescent and adult people with haemophilia A without factor VIII inhibitors-A non-interventional study.

INTRODUCTION: Real-world data on health-related outcomes in persons with haemophilia A (PwHA) can provide useful information for improving patient care. The global, non-interventional study (NIS; NCT02476942) prospectively collected high-quality data in PwHA, including those without factor VIII (FVIII) inhibitors treated according to local routine clinical practice. AIM: To report health-related quality of life (HRQoL) and health status of adult/adolescent PwHA without FVIII inhibitors. METHODS: Participants were PwHA without FVIII inhibitors age ≥12 years; they remained on existing episodic treatment or prophylaxis. HRQoL was assessed by Haemophilia Quality of Life Questionnaire for Adults (Haem-A-QoL) or Haemophilia-Specific Quality of Life Assessment for Children and Adolescents Short Form (Haemo-QoL-SF II). Health status was assessed through EuroQol 5-Dimensions 5-Levels (EQ-5D-5L) index utility score and visual analogue scale (EQ-VAS). RESULTS: Ninety-four participants enrolled; median age was 34.0 years (range 12-76). Forty-five received episodic treatment and 49 received prophylaxis for a median time of 27.7 weeks and 30.4 weeks, respectively. Mean (standard deviation) baseline Haem-A-QoL total scores were 40.1 (17.0) for the episodic group and 26.6 (14.6) for the prophylaxis group, indicating impairments in HRQoL, which remained consistent over time. Mean EQ-5D-5L IUS scores were similar between treatment regimens (0.8 episodic; 0.9 prophylaxis) and consistent over time. The mean EQ-VAS scores were similar between treatment regimens, and lower on days when bleeding occurred (79.0 vs 85.0 for episodic treatment; 77.0 vs 82.0 for prophylaxis, respectively). CONCLUSIONS: Adult and adolescent PwHA without FVIII inhibitors had HRQoL impairments regardless of whether they were treated with episodic or prophylactic standard care with FVIII.

Clinical phenotype, fibrinogen supplementation, and health-related quality of life in patients with afibrinogenemia.

Due to the low prevalence of afibrinogenemia, epidemiologic data on afibrinogenemia are limited, and no data are available on health-related quality of life (HRQoL). We conducted a cross-sectional international study to characterize the clinical features, the fibrinogen supplementation modalities, and their impact on HRQoL in patients with afibrinogenemia. A total of 204 patients (119 adults and 85 children) from 25 countries were included. The bleeding phenotype was severe: 68 (33.3%) patients having at least one bleed per month and 48 (23%) a history of cerebral bleeding. About 35% (n = 72) of patients were treated with fibrinogen concentrates or cryoprecipitates as prophylaxis, 18.1% (n = 37) received ≥1 injection per week, and 16.6% (n = 34) were on home treatment. A thrombotic event was reported in venous and/or arterial territories by 37 (18.1%) patients. Thrombosis occurred even in young patients, and recurrence was frequent (7.4%). The total HRQoL was lower in children than in adults. Discomfort linked to treatment and limitations to sports and leisure were the main concerns. Women and children were particularly affected in family relationships. In multivariate analyses, younger age, residence in Asia or Africa, and a previous thrombotic event were statistically correlated with a worse HRQoL. In summary, our study underlines the severe bleeding and thrombotic phenotype and their impact on HRQoL in afibrinogenemia. The optimal strategy for fibrinogen supplementation needs to be determined. This trial was registered at www.clinicaltrials.gov as #NCT03484065.

Cross-Sectional and Longitudinal Construct Validity of the Generic KINDL-A(dult)B(rief) Questionnaire in Adults with Thrombophilia or with Hereditary and Acquired Bleeding Disorders.

BACKGROUND/AIMS: The newly adapted generic KINDL-A(dult)B(rief) questionnaire showed satisfactory cross-sectional psychometric properties in adults with bleeding disorders or thrombophilia. This investigation aimed to evaluate its cross-sectional and longitudinal construct validity. METHODS: After ethical committee approval and written informed consent, 335 patients (mean age 51.8 ± 16.6 years, 60% women) with either predominant thrombophilia (n = 260) or predominant bleeding disorders (n = 75) participated. At baseline, patients answered the KINDL-AB, the MOS 36-item Short-Form Health Survey (SF-36), and the EQ-5D-3L. A subgroup of 117 patients repeated the questionnaire after a median follow-up of 2.6 years (range: 0.4-3.5). A priori hypotheses were evaluated regarding convergent correlations between KINDL-AB overall well-being and specific subscales, EQ-5D-3L index values (EQ-IV), EQ-5D visual analog scale (EQ-VAS), and SF-36 subscales. RESULTS: Contrary to hypothesis, baseline correlations between the KINDL-AB and EQ-IV/EQ-VAS were all moderate while, as hypothesized, several KINDL-AB subscales and SF-36 subscales correlated strongly. At follow-up, no significant changes in all three instruments occurred. Correlations between instruments over the follow-up were mostly moderate and partially strong. Contrary to hypothesis but consistent with no significant changes in health-related quality of life, convergent correlations between changes in KINDL-AB overall well-being, physical and psychological well-being, and EQ-IV/EQ-VAS were all weak. CONCLUSIONS: While repeated measures of KINDL-AB showed moderate to strong correlations, changes in KINDL-AB overall well-being and subscales correlated more weakly than expected with changes involving two established instruments of generic health status.

Determining meaningful health-related quality-of-life improvement in persons with haemophilia A using the Haemophilia Quality of Life Questionnaire for Adults (Haem-A-QoL).

INTRODUCTION: The Haem-A-QoL is frequently utilized in haemophilia clinical trials and captures relevant aspects of disease impact. Thresholds for some domains 'Physical Health' (PH), 'Sports & Leisure' (S&L) and 'Total Score' (TS) have previously been identified to benchmark the amount of change that is meaningful to patients, but not been independently confirmed. AIM: The objective of this analysis was to determine the clinically important responder (CIR) thresholds for these three domains. METHODS: CIR thresholds in adult persons with haemophilia A (PwHA) enrolled in HAVEN 1, 3 and 4 studies were determined for improvements from baseline to 24 weeks of emicizumab prophylaxis using anchor-based methodology with the EQ-5D-5L as the validated anchor, cumulative distribution functions (CDF) and distribution-based methodology. The results were compared with previously published thresholds. RESULTS: At baseline and after 24 weeks of emicizumab prophylaxis, Haem-A-QoL data from 241/258 patients were available. Concordance was observed between the Haem-A-QoL and EQ-5D-5L in patterns of improvement, deterioration or lack of change. CDF estimates of the Haem-A-QoL PH and TS grouped by response categories on the Mobility, Pain/Discomfort and Usual Activities EQ-5D-5L domains demonstrated the same pattern of responses to each scale; distribution-based estimates were 11.9 for PH, 13.9 for S&L, and 8.3 for TS. CONCLUSION: Our responder thresholds are mostly consistent with those proposed by Wyrwich et al (cut-offs of -10 and -7 for PH and TS, respectively). The majority of responders to emicizumab prophylaxis had improvements greater than the previously reported 10-point reduction in PH and 7-point reduction in TS.

Health-related quality of life and caregiver burden of emicizumab in children with haemophilia A and factor VIII inhibitors-Results from the HAVEN 2 study.

INTRODUCTION: Persons with haemophilia A (PwHA) with factor (F)VIII inhibitors, including children, have impaired health-related quality of life (HRQoL). The HAVEN 2 study (NCT027955767) of paediatric PwHA with FVIII inhibitors demonstrated that subcutaneous emicizumab prophylaxis resulted in low annualizedbleed rates. AIM: We assessed the impact of emicizumab prophylaxis on the HRQoL of children and their caregivers participating in HAVEN 2. METHODS: Children aged 8-11 years self-reported HRQoL using the Haemophilia-Specific Quality of Life Assessment Instrument for Children and Adolescents Short Form (Haemo-QoL SF II). Caregivers of children aged 0-11 years completed the Adapted Inhibitor-Specific Quality of Life Assessment with Aspects of Caregiver Burden. All scores were transformed to a 0-100 scale, where lower scores reflect a better HRQoL. The number of missed days from school/day care and hospitalizations was also recorded. RESULTS: In HAVEN 2 (n = 88), the median age was 6.5 years (range: 1-15 years); 85 participants were aged < 12 years and included in this analysis, and 34 participants were aged 8-11 years, thereby eligible to complete the Haemo-QoL SF II questionnaire. The mean (standard deviation, n) baseline Haemo-QoL SF II 'Total' score was 30.2 (14.9, 30), indicating moderate impairment; with emicizumab, mean score decreased by -9.62 (7.73, 17) points to 23.0 (13.93, 20) by Week 49. The most improved domains were 'Sports & School' and 'Physical Health'. Caregivers reported similar improvements. CONCLUSION: Prophylactic emicizumab is accompanied by substantial and sustained improvements in HRQoL of paediatric PwHA with FVIII inhibitors and their caregivers.

Challenges and key lessons from the design and implementation of an international haemophilia registry supported by a pharmaceutical company.

INTRODUCTION: Real-world data are lacking regarding the relationship between prospectively collected patient-reported outcomes (PROs), clinical outcomes and treatment in people with haemophilia (PWH). The Expanding Communications on Hemophilia A Outcomes (ECHO) registry was designed to address this data gap, but a range of difficulties led to early study closure. AIM: To describe the challenges faced and lessons learned from implementing a multinational haemophilia registry. METHODS: The Expanding Communications on Hemophilia A Outcomes was planned as a five-year observational cohort study to collect data from 2000 patients in nine countries. Based on direct observations, feedback from patients enrolled in ECHO, challenges of the study design and input from study-sponsor representatives, the ECHO Steering Committee systematically identified the challenges faced and developed recommendations for overcoming or avoiding them in future studies. RESULTS: The study closed after two years because few countries were activated and patient recruitment was low. This was related to multiple challenges including delayed implementation, stringent pharmacovigilance requirements, objections of investigators and patients to the burden of multiple PROs, data collection issues, lack of resources at study sites, little engagement of patients and competing clinical trials, which further limited recruitment. At study closure, 269 patients had been enrolled in four of nine participating countries. CONCLUSIONS: Researchers planning studies similar to ECHO may want to consider the barriers identified in this global registry of PWH and suggestions to mitigate these limitations, such as greater patient involvement in design and analysis, clearer assessment and understanding of local infrastructure and potential changes to the administration of the study.

Evaluation of the U.S. Adherence Questionnaires VERITAS-PRO and VERITAS-PRN for Use in Patients with Hemophilia in the German Healthcare System.

AIM: Since the U.S. adherence instruments VERITAS-PRO and VERITAS-PRN were developed in another healthcare system, we assumed that they are not appropriate for the German solidarity healthcare system. This study aims to evaluate the relevance of these instruments for the German healthcare system both by people with hemophilia (PWH) and by healthcare professionals (HCP). METHODS: A total of 50 PWH (23 adult hemophilia patients and 27 parents of children with hemophilia) and 25 HCP rated the relevance of the single items of the VERITAS-PRO and VERITAS-PRN on a 5-point Likert scale. In addition, both groups were asked to make suggestions for additional adherence questions. To investigate the relevance of these instruments, the accordance between the raters' evaluations was determined calculating the content validity index (CVI) and the content validity ratio (CVR) based on the critical values of the CVR (CVRcritical) to exclude chance and subjectivity. RESULTS: CVI (CVR) calculations revealed three (5) "very important" items for PWH and six (11) items for HCP. Only two (3) "very important" items were evaluated by both groups. Four domains were considered not important by both groups. Six PWH made 14 suggestions and 14 HCP made 24 suggestions for additional adherence questions. CONCLUSION: VERITAS-PRO and VERITAS-PRN have only very limited benefits for the German healthcare system. Since nonadherence has a great impact on the morbidity of PWH and on the costs for the healthcare system, there is a need for adherence instruments that are adapted to the specific needs of PWH in the German healthcare system.

Impact of COVID-19 pandemic on mental health of patients with inherited bleeding disorders in Germany.

BACKGROUND: The worldwide pandemic spread of SARS-CoV-2 can lead to either respiratory infection or containment-associated isolation with possible higher impact on chronic diseases such as inherited bleeding disorders (IBD). The aim of the study was to evaluate the impact of COVID-19 on patients and caregivers of IBD patients regarding their concerns and worries related to own health, access to treatment and availability of factor concentrates and their experiences related to medical care. METHODS: Multicentre, cross-sectional study evaluating the impact of COVID-19 on mental health of IBD patients. An ad hoc questionnaire was developed and sent to 586 patients/caregivers with haemophilia A, haemophilia B and VWD type III. The survey included information on demographic and clinical data, needs, concerns and experiences regarding medical care during COVID-19 pandemic. RESULTS: In total, 355 of the IBD-Group (200 patients, 155 caregivers) completed the survey (61.7% response rate). Most patients suffered from haemophilia A (73.8%) and were severely affected (64.7%). Eleven patients were in quarantine due to suspected COVID-19; none had symptoms. One quarter worried (very) strongly about getting the coronavirus, 71.3% asked themselves what will happen to them when they will get COVID-19, 40.1% felt unchanged, and 18.9% worried about delivery difficulties of their IBD treatment product. In 52.8%, medical appointments were postponed. Significant differences between caregivers and patients were found in most aspects. DISCUSSION: The IBD patients affected by a chronic disorder have particular thoughts and worries regarding COVID-19. Haemophilia specialists should be committed to address these concerns and guarantee treatment despite containment strategies.

Outcomes in children with hemophilia A with inhibitors: Results from a noninterventional study.

BACKGROUND: Data regarding management of pediatric persons with hemophilia A (PwHA) with factor VIII (FVIII) inhibitors are limited. This prospective noninterventional study (NCT02476942) evaluated annualized bleeding rates (ABRs), safety, and health-related quality of life (HRQoL) in pediatric PwHA with FVIII inhibitors. PROCEDURE: PwHA aged <12 years with current FVIII inhibitors and high-titer inhibitor history were enrolled. Participants remained on usual treatment; no interventions were applied. Outcomes included ABR, safety, and HRQoL. RESULTS: Twenty-four PwHA aged 2-11 years (median 7.5) were enrolled and monitored for 8.7-44.1 weeks (median 23.4). In the episodic (n = 10) and prophylactic (n = 14) groups, respectively, 121 of 185 (65.4%) and 101 of 186 (54.3%) bleeds were treated using activated prothrombin complex concentrate (aPCC) and/or recombinant activated FVII (rFVIIa). ABRs (95% confidence interval) were 19.4 (13.2-28.4) and 18.5 (14.2-24.0) for treated bleeds, and 32.7 (20.5-52.2) and 33.1 (22.4-48.9) for all bleeds, respectively. Most prophylactic group participants (92.9%) were prescribed aPCC; 50% adhered to their prescribed treatment regimen. Adherence to prophylactic rFVIIa was not assessed. Serious adverse events included hemarthrosis (12.5%) and mouth hemorrhage (12.5%); the most common nonserious adverse event was viral upper respiratory tract infection (12.5%). HRQoL showed functional impairment at baseline; scores remained stable throughout, with little intergroup variation. CONCLUSIONS: ABRs remained high in pediatric PwHA with inhibitors receiving standard treatment. This study demonstrates the need for more effective treatments, with reduced treatment burden, to prevent bleeds, increase prophylaxis adherence, and improve patient outcomes.

Cross-cultural adaptation and validation of Haem-A-QoL in Côte d'Ivoire.

INTRODUCTION: Health-related quality (HRQoL) evaluations are considered essential outcomes in the assessment of people with haemophilia. In developing countries, reliable HRQoL data are even more critical whilst enabling government agencies to develop national haemophilia care programmes. However, validated tools are not yet available in sub-Saharan African countries. AIMS: This study sought to perform a cultural adaptation and validation of the Haemophilia Quality of Life Questionnaire for Adults (Haem-A-QoL) in Côte d'Ivoire. METHODS: The process comprised several steps, such as linguistic adaptation, cognitive debriefing interviews with adult haemophilia patients and psychometric testing, including reliability (internal consistency, test-retest reliability) and validity assessments (convergent with EQ-5D-5L, criterion with HJHS 2.1, known-groups). RESULTS: The final Ivoirian Haem-A-QoL version was obtained in December 2017 following linguistic adaptation and cognitive debriefings with six participants. The validation process included 25 patients, mainly haemophilia A patients (88%) with severe forms (80%). All participants received on-demand treatment, with joint impairment observed in 92%. Internal consistency and test-retest reliability of the Ivoirian Haem-A-QoL were very good. A Pearson correlation analysis revealed a moderate negative correlation between EQ-VAS and total Haem-A-QoL scores and a moderate positive correlation between HJHS 2.1 and total Haem-A-QoL scores. CONCLUSIONS: A cross-culturally adapted and validated Haem-A-QoL version in Côte d'Ivoire is now available, enabling measurement of intervention outcomes in the targeted population and Ivorian participation to multisite international trials. However, further work is needed to ensure optimal understanding of HRQoL questionnaires, previously developed in culturally distinct countries, with almost unlimited access to different treatment regimens.

Heavy menstrual bleeding in women with inherited bleeding disorders.

Heavy menstrual bleeding (HMB) is the commonest bleeding symptom among women with inherited bleeding disorders (IBD). Since HMB starts at the very onset of menarche and continues throughout the reproductive life, the health related quality of life of these women is affected and they are at an increased risk of developing iron-deficiency anemia. Because of the entrenched stigma and taboos, women and girls are often reluctant to discuss the problem of HMB within their families and do not seek medical advice. Increased awareness and multidisciplinary management approach for the management of these women are essential in ensuring an optimal outcome. It is important to take a careful history and undertake a thorough gynecological assessment to exclude other underlying/concomitant causes of HMB. Iron supplementation is essential. Strategies for decreasing menstrual blood flow are similar to those used for HMB in general with the addition of desmopressin and replacement therapy and the exclusion of non-steroidal anti-inflammatory drugs. Tranexamic acid and/or hormonal intervention are usually recommended as first-line therapy. Treatment choice should be individualized taking into account whether the woman wishes to preserve her fertility, if she requires contraception, the type of IBD, the severity of bleeding, and her social and religious background as well as acceptability and availability of the treatment options.

Health-Related Quality of Life, Treatment Satisfaction and Adherence Outcomes of Haemophilia Patients Living in a German Rural Region.

In the context of the 'Mobile Haemophilia Outpatient Care (MHOC)' project we aimed to gather insights into the health-related quality of life (HRQoL), treatment satisfaction (TS) and adherence of persons with haemophilia (PWHs) who get treated at the Saarland University Hospital Haemophilia Treatment Centre (HTC). PWHs were visited at home at least twice (baseline, follow-up) by trained medical staff. Individual interviews were performed to measure patients' HRQoL and TS with validated questionnaires (Haem-A-QoL/Haemo-QoL and Hemo-SatA/Hemo-SatP). Socio-demographic and clinical data were collected. In total, 79 PWHs were enrolled; 56 adults with a mean age of 37.4 ± 16.4 years (17-78) and 23 children [mean age of 9.8 ± 4.2 years (3-16)]. In total, 62% were severely affected; 48.1% received prophylaxis. Patients reported good HRQoL (adults: 23.1 ± 17.1; kids: 24.3 ± 11.1). Patients (M = 11.2 ± 9.5) and parents (M = 14.3 ± 7.4) were very satisfied with their provided treatment. The majority of study participants were evaluated to have a good treatment adherence. After 1-year follow-up of the MHOC, a significant improvement in HRQoL was seen in adults (p < 0.033) and in proxy ratings of parents (p < 0.0001); TS remained high with no change by MHOC intervention. Patients reported good HRQoL and TS. Most of them were evaluated as having a good treatment adherence. After implementation of the MHOC, adult patients reported a better HRQoL. Such a mobile medical care service is considered beneficial for patients, especially with limited access to a HTC.

BAY 81-8973 prophylaxis and pharmacokinetics in haemophilia A: Interim results from the TAURUS study.

OBJECTIVES: To report interim data from TAURUS, a study assessing real-world prophylactic treatment with unmodified, full-length recombinant FVIII BAY 81-8973 (Kovaltry® ; Bayer) indicated for haemophilia A. METHODS: TAURUS (NCT02830477) is an international, open-label, prospective, non-interventional, single-arm study with a one-year observation period (target N = 350). Patients have moderate or severe haemophilia A (FVIII ≤5% or ≤1%) and ≥50 exposure days to any FVIII product. Clinician- and patient-reported outcomes are captured on previous product use, changes in prophylaxis dose and dosing frequency, FVIII consumption, reported bleeding rates, treatment satisfaction and adherence, pharmacokinetic (PK) data (if available) and safety data. RESULTS: At cut-off, baseline data were available from 160 patients (89 had ≥6 months of follow-up data). Most patients had severe haemophilia A (85%), infused BAY 81-8973 ≥ 3×/wk (59%) and experienced a median number of total bleeds of 2.0 (non-annualised; 246 days median documentation period). Good levels of treatment satisfaction (Hemo-SATA,P ) and adherence (VERITAS-Pro) were maintained. TAURUS demonstrated a favourable PK profile of BAY 81-8973 in comparison with other standard half-life rFVIIIs and supported the WAPPS PopPK model. No patients developed inhibitors. CONCLUSIONS: TAURUS data demonstrate effective prophylaxis with BAY 81-8973 in the real world without compromising patient satisfaction or adherence.
