Patient Experience of Living With Hemophilia A: A Conceptual Model of Humanistic and Symptomatic Experience in Adolescents, Adults, and Children.

People living with hemophilia A face challenges impacting their daily lives despite treatment innovations. Previous studies have explored perceptions and treatment experiences; however, there is a lack of an evidence-based, comprehensive model to identify concepts (clinical, physical, and psychological functioning) relevant for people with hemophilia A (PwHA). The aim of this qualitative study was to address the question: What is the humanistic and symptomatic experience of adolescents, adults, and children living with hemophilia A and what is the impact of hemophilia A on their quality of life? Participants, identified through patient associations in the UK, were male PwHA and caregivers of male PwHA receiving prophylactic treatment.

Superior Prophylactic Effectiveness of a Recombinant FVIIIFc Over Standard Half-Life FVIII in Hemophilia A: A-SURE Study.

Objectives: The 24-month, prospective, non-interventional, European multicenter A-SURE study evaluated the real-world effectiveness of prophylaxis using an extended half-life recombinant factor VIII (FVIII) Fc fusion protein, efmoroctocog alfa (hereinafter rFVIIIFc), compared with prophylaxis using standard half-life (SHL) FVIII products in patients with hemophilia A.

Methods: Primary endpoints were annualized bleeding rate (ABR), annualized injection frequency, and annualized factor consumption. A comparative study design unique for an observational hemophilia study was implemented to reduce potential confounding in effectiveness estimates, wherein each patient prescribed rFVIIIFc was matched with one receiving SHL FVIII.

Assessment of joint health in patients receiving prophylaxis for haemophilia A: a cross-sectional survey in five European countries.

Objectives: To evaluate joint health, pain and health-related quality of life (HRQoL) in patients with moderate/severe haemophilia A in Europe.

Design: Multinational, cross-sectional survey, with retrospective data collection. Data were taken from the Adelphi Real World Haemophilia Disease Specific Programme Wave II, using surveys completed by physicians and patients between February 2020 and May 2021.

Long-term efmoroctocog alfa prophylaxis improves perceived pain, mental, and physical health in patients with hemophilia A: analysis of phase III trials using patient-reported outcomes.

Background: Hemophilia-associated bleeding and resultant joint pain and mobility restrictions can predispose patients to poor health-related quality of life (HRQoL). Therefore, efficacy of a treatment needs to address more than just annualized bleed rates.

Objectives: Describe the evolution of HRQoL, pain, and activity in patients with hemophilia A, treated with efmoroctocog alfa prophylaxis.

Long-term outcomes of prophylaxis with a recombinant factor VIII Fc or recombinant factor IX Fc in patients with hemophilia previously treated on demand.

Background: Prophylactic factor replacement therapy is recommended over on-demand treatment for preserving long-term joint health in hemophilia. Extended half-life products, including efmoroctocog alfa/eftrenonacog alfa (recombinant factor VIII [FVIII]/FIX Fc fusion proteins; herein rFVIIIFc/rFIXFc), have the potential to reduce treatment burden with less frequent administration and improve bleed prevention.

Objectives: We report post hoc data from patients with hemophilia A or B (HA/HB) who switched from prestudy on-demand FVIII/FIX to rFVIIIFc/rFIXFc prophylaxis at the start of A-LONG/B-LONG or start of/during ASPIRE/B-YOND phase 3 studies.

Real-world evidence on efmoroctocog alfa in patients with haemophilia A: A systematic literature review of treatment experience in Europe.

Introduction: The real-world effectiveness of the efmoroctocog alfa (recombinant FVIII Fc fusion protein, a rFVIIIFc) has been investigated in numerous studies, however, currently, there exists no comprehensive collection of the existing real-world evidence (RWE) on the performance of prophylactic use of rFVIIIFc.

Aim: The aims of this systematic literature study were to identify, review, evaluate and collate the RWE of prophylactic rFVIIIFc for patients with haemophilia A reported in Europe.

Methods: We searched Medline and Embase from 2014 to February 2022 to identify publications reporting the effectiveness of rFVIIIFc in patients with haemophilia A.

Cost-effectiveness of recombinant factor VIII Fc versus emicizumab for prophylaxis in adults and adolescents with haemophilia A without inhibitors in the UK.

Introduction: The economic and clinical burden of haemophilia A is high. Primary prophylaxis with factor VIII replacement therapy is the recognised standard of care, but the emergence of non-factor therapies, such as emicizumab, is extending treatment options for people with haemophilia A.

Aim: There are currently no direct comparisons of efficacy or cost between recombinant factor FVIII Fc-fusion protein efmoroctocog alfa (a recombinant factor FVIII Fc-fusion protein referred to herein as rFVIIIFc) and emicizumab; therefore, a cost-effectiveness model was developed to compare prophylactic treatment with rFVIIIFc versus emicizumab in patients with haemophilia A without inhibitors in the UK.
