Anchored Indirect Treatment Comparison Finds Comparable Effects of Pegcetacoplan and Iptacopan in Paroxysmal Nocturnal Haemoglobinuria.

Background: Paroxysmal nocturnal haemoglobinuria (PNH) is an ultra-rare, acquired non-malignant haematological disorder characterised by thrombosis risk, serious complications and debilitating symptoms in untreated patients.

Objective: This anchored indirect treatment comparison (ITC) evaluated efficacy data between proximal complement 3 inhibitor (C3i) pegcetacoplan and factor B inhibitor, iptacopan, in patients with PNH previously treated with complement 5 inhibitors (C5i; eculizumab, ravulizumab).

Methods: Respective pivotal studies provided patient-level trial data for pegcetacoplan (16-week PEGASUS [NCT03500549]) and published data for iptacopan (24-week APPLY PNH [NCT04558918]).

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.

Mapping the EORTC QLQ-C30 onto the EQ-5D-5L index for patients with paroxysmal nocturnal hemoglobinuria in France.

To map patient-level data collected on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC) QLQ-C30 to EQ-5D-5L data for estimating health-state utilities in patients with paroxysmal nocturnal hemoglobinuria (PNH). European cross-sectional PNH patient survey data populated regression models mapping EORTC QLQ-C30 domains (covariates: sex and baseline age) to utilities calculated with the EQ-5D-5L French value set. A genetic algorithm allowed selection of the best-fitting between a set of models with and without interaction terms.

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.

The burden of illness of patients with paroxysmal nocturnal haemoglobinuria receiving C5 inhibitors: clinical outcomes and medical encounters from the patient perspective.

Methods: The model was based on 100 patients from the healthcare payer perspective in the UK, France, Italy, Spain, and Germany (5-year time horizon). Costs included: drug acquisition; emicizumab wastage by bodyweight (manufacturer's dosing recommendations); and additional FVIII for breakthrough bleeds.

Changes in hemoglobin and clinical outcomes drive improvements in fatigue, quality of life, and physical function in patients with paroxysmal nocturnal hemoglobinuria: post hoc analyses from the phase III PEGASUS study.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, chronic, acquired, hematologic, life-threatening disease characterized by thrombosis, impaired bone marrow function, and complement-mediated hemolysis. The PEGASUS phase III clinical trial demonstrated superiority of pegcetacoplan over eculizumab regarding improvements in hemoglobin levels in patients with suboptimal response to prior eculizumab treatment. The objective of this post hoc analysis was to compare the patient-reported outcome (PRO) response rates observed among PEGASUS participants and the relationships between their PRO scores with clinical and hematological parameters.

The cost-effectiveness, of pegcetacoplan compared with ravulizumab for the treatment of paroxysmal nocturnal hemoglobinuria, in a UK setting.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare blood disorder characterized by hemolytic anemia, bone marrow failure and thrombosis. We evaluated, the cost-effectiveness of pegcetacoplan, a novel proximal C3 inhibitor, versus ravulizumab in patients with PNH and hemoglobin levels <10.5 g/dl despite eculizumab treatment in the UK healthcare and social services setting.

Health-related quality of life, direct medical and societal costs among children with moderate or severe haemophilia in Europe: multivariable models of the CHESS-PAEDs study.

Background: Haemophilia bears substantial humanistic and economic burden on children and their caregivers. Characterising the differential impact of severe versus moderate paediatric haemophilia is important for clinical and health policy decisions. We analysed health-related quality of life (HRQoL), annual direct medical (excluding factor treatment costs), non-medical and societal costs among children and adolescents with moderate and severe haemophilia A or B without inhibitors from the European CHESS-PAEDs study.

Differential humanistic and economic burden of mild, moderate and severe haemophilia in european adults: a regression analysis of the CHESS II study.

Background: The lifelong nature of haemophilia makes patient-centred and societal assessments of its impact important to clinical and policy decisions. Quantifying the humanistic and economic burden by severity is key to assessing the impact on healthcare systems. We analysed the annual direct medical (excluding factor replacement therapy costs) and non-medical costs as well as societal costs and health-related quality of life (HRQoL) of mild, moderate and severe disease among adults with haemophilia A or B without inhibitors in Europe.

Improvement in pain-related quality of life in patients with hemophilia A treated with rFVIIIFc individualized prophylaxis: post hoc analysis from the A-LONG study.

Background: Pain, a common symptom of hemophilia, begins early in life primarily due to joint bleeding. Recurrent bleeding adversely affects patients' pain-related physical functioning, which can negatively impact their quality of life (QoL).

Objective: Post hoc analysis of data from the A-LONG study (NCT01181128), to assess change over time in pain-related QoL in patients with severe hemophilia A treated prophylactically with recombinant factor VIII Fc fusion protein (rFVIIIFc).

rFIXFc prophylaxis improves pain and levels of physical activity in haemophilia B: Post hoc analysis of B-LONG using haemophilia-specific quality of life questionnaires.

Introduction: Recurrent bleeding in severe haemophilia B causes painful hemarthroses and reduces capacity for physical activity. Recombinant factor IX Fc fusion protein (rFIXFc) prophylaxis results in low annualised bleeding rates, with the potential to improve patients' health-related quality of life (HRQoL).

Aim: To present a post hoc analysis of data from B-LONG describing change over time in patient-reported outcomes associated with pain and physical activity.

Characterization and treatment of immune thrombocytopenia in Europe: a qualitative observational study.

Background: Immune thrombocytopenia (ITP) is a rare disease, characterized by increased platelet destruction/suboptimal platelet production, leading to thrombocytopenia and risk of severe bleeding events.

Methods: Interviews with 23 physicians and 12 payors, a survey with 113 physicians and validation using published data were used to define the current treatment paradigm and healthcare resource utilization and to determine the costs associated with managing acute bleeds in six European countries (Germany, Spain, France, Italy, Netherlands, UK). The study estimated a prevalence of 9 to 10 per 100,000 adults in 2020 across all six countries (disease severity split: 34% mild, 32% moderate, 33% severe (due to rounding up some values might not sum up to 100%).

Patient preferences and experiences regarding thrombopoietin-receptor agonists for immune thrombocytopenia in the United Kingdom and Ireland (TRAPeze UK & IE study).

Objectives: To establish the experiences with and preferences towards existing thrombopoietin-receptor agonist (TPO-RA) treatments of individuals with immune thrombocytopenia (ITP) in the UK and Ireland, based on treatment attributes.

Methods: Responses from UK and Ireland individuals with ITP were collected in a pan-European online survey (TRAPeze, [Thrombopoietin-Receptor Agonist Patient experience survey]) from 18 September 2020 to 18 February 2021. TRAPeze was a survey of treatment preference regarding TPO-RAs (using a discrete choice experiment design), participant demographics, disease characteristics, treatment history, overall satisfaction with therapy, direct healthcare resource utilization and wider social impact.

An Economic Comparison of Treatment Strategies with Anakinra in Systemic Juvenile Idiopathic Arthritis (sJIA).

Introduction: Systemic juvenile idiopathic arthritis (sJIA) is a rare, complex autoinflammatory disease with substantial morbidity, often characterized by fever, rash, and muscle pain, amongst other symptoms. Biologic agents, such as anakinra, have been successfully used to treat patients internationally, but their usage in some regions is limited to patients that have failed to achieve clinically inactive disease with corticosteroids and conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). Use of anakinra early in the disease course leads to better clinical outcomes; however, longer-term costs for this treatment strategy have not been established.

Anticholinergic Burden and Associated Healthcare Resource Utilization in Older Adults with Overactive Bladder.

Background: Bladder anticholinergics are the most widely used drugs to treat overactive bladder (OAB) but can contribute to cumulative anticholinergic burden, which may be associated with adverse outcomes.

Objective: This study aimed to evaluate the association between cumulative anticholinergic burden and healthcare resource utilization (HRU) and costs in older adults with OAB.

Materials And Methods: This was a retrospective, observational study that used data from the UK Clinical Practice Research Datalink (CPRD) GOLD database.

Efficacy of rFIXFc versus rIX-FP for the Treatment of Patients with Hemophilia B: Matching-Adjusted Indirect Comparison of B-LONG and PROLONG-9FP Trials.

Purpose: In patients with hemophilia B, treatment with extended half-life (EHL) recombinant factor IX allows for longer dosing intervals while providing equal or superior bleeding protection compared with standard half-life products. This enables flexible, individualized treatment schedules, which reduce the burden of prophylaxis and improve patient outcomes. This analysis compared the efficacy of recombinant factor IX Fc fusion protein (rFIXFc) and recombinant factor IX albumin fusion protein (rIX-FP), two EHL therapies approved for prophylaxis and treatment of bleeding in hemophilia B.
