Abstract
The management of hemophilia A has undergone a remarkable revolution, in line with technological advancement. In the recent past, the primary concern associated with Factor VIII (FVIII) concentrates was the risk of infections, which is now almost resolved by advanced blood screening and viral inactivation methods. Improving patients' compliance with prophylaxis has become a key focus, as it can lead to improved health outcomes and reduced health care costs in the long term. Recent bioengineering research is directed toward prolonging the recombinant FVIII (rFVIII) coagulant activity and synthesising higher FVIII yields. As an outcome, B-domain deleted, polyethylene glycolated, single-chain, Fc-fused rFVIII, and rFVIIIFc-von Willebrand Factor-XTEN are available for patients. Moreover, emicizumab, a bispecific antibody, is commercially available, whereas fitusiran and tissue factor pathway inhibitor are in clinical trial stages as alternative strategies for patients with inhibitors. With these advancements, noninfectious complications, such as inhibitor development, allergic reactions, and thrombosis, are emerging concerns requiring careful management. In addition, the recent approval of gene therapy is a major milestone toward a permanent cure for hemophilia A. The vast array of treatment options at our disposal today empowers patients and providers alike, to tailor therapeutic regimens to the unique needs of each individual. Despite significant progress in modern treatment options, these highly effective therapies are markedly more expensive than conventional replacement therapy, limiting their access for patients in developing countries.

Abdelgawad HAH, Foster R, Otto M. Nothing short of a revolution: Novel extended half-life factor VIII replacement products and non-replacement agents reshape the treatment landscape in hemophilia A. Blood Rev 2024; 64:101164. [PMID: 38216442 DOI: 10.1016/j.blre.2023.101164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 01/14/2024]
Abstract
Hemophilia A, an X-linked genetic disorder, is characterized by a deficiency or dysfunction of clotting Factor VIII. The treatment landscape has substantially changed by introducing novel extended half-life factor VIII (EHL-FVIII) replacement therapies such as efanesoctocog Alfa and non-factor replacement therapy such as emicizumab. These agents signal a shift from treatments requiring multiple weekly infusions to advanced therapies with long half-lives, offering superior protection against bleeding and improving patient adherence and quality of life. While EHL-FVIII treatment might lead to inhibitor development in some patients, non-factor replacement therapy carries thrombotic risks. Therefore, ongoing research and the generation of robust clinical evidence remain vital to guide the selection of optimal and cost-effective first-line therapies for hemophilia A patients.

Abstract
Conjugation of polyethylene glycol (PEGylation) to blood proteins and cells has emerged as a successful approach to address some of the issues attributed to the storage of blood products, including their short half-life and instability. In this regard, this review study aims to compare the influence of different PEGylation strategies on the quality of several blood products like red blood cells (RBCs), platelets, plasma proteins, i.e., albumin, coagulation factor VIII, and antibodies. The results indicated that conjugating succinimidyl carbonate methoxyPEG (SCmPEG) to platelets could improve blood transfusion safety by preventing these cells from being attached to low-load hidden bacteria in blood products. Moreover, coating of 20 kD succinimidyl valerate (SVA)-mPEG to RBCs was able to extend the half-life and stability of these cells during storage, as well as immune camouflage their surface antigens to prevent alloimmunisation. As regards albumin products, PEGylation improved the albumin stability, especially during sterilization, and there was a relationship between the molecular weight (MW) of PEG molecules and the biological half-life of the conjugate. Although coating antibodies with short-chain PEG molecules could enhance their stabilities, these modified proteins were cleared from the blood faster. Also, branched PEG molecules enhanced the retention and shielding of the fragmented and bispecific antibodies. Overall, the results of this literature review indicate that PEGylation can be considered a useful tool for enhancing the stability and storage of blood components.

Abstract
INTRODUCTION Hemophilia A is a severe bleeding disorder affecting about 1 in 5,000 males. The gold standard for prophylaxis and treatment of acute bleeding has been factor (F) VIII concentrate. A multitude of treatment modalities are now available and under clinical investigation. AREAS COVERED This review discusses ongoing/recently completed early-phase clinical trials registered on ClinicalTrials.gov in patients with hemophilia A through April 2022. These new pipeline therapies are focused on addressing the safety and efficacy of new factor-related products, non-factor related products, and gene therapy options for hemophilia. EXPERT OPINION Current standard of care effectively prevents and treats acute bleeding and has significantly improved the quality of life in hemophilia. The biggest challenges in the improvement of care are treatment-related burden and the burden of cost in developing countries. New drugs under development are likely to enter practice by the end of this decade and address many of the unmet needs particularly of those with severe disease. Data is limited in unique populations (e.g. congenital/inherited FVIII inhibitors, non-severe hemophilia A, women/girls with hemophilia and children) which are important areas for future research; additional clinical trials and long-term outcome data are necessary prior to incorporating these new therapies in our treatment arsenal.

Abstract
Hemophilia A (HA) and hemophilia B (HB) are rare disorders, being caused by the total lack or under-expression of two factors from the coagulation cascade coded by genes of the X chromosome. Thus, in hemophilic patients, the blood does not clot properly. This results in spontaneous bleeding episodes after an injury or surgical intervention. A patient-centered regimen is considered optimal. Age, pharmacokinetics, bleeding phenotype, joint status, adherence, physical activity, personal goals are all factors that should be considered when individualizing therapy. In the past 10 years, many innovations in the diagnostic and treatment options were presented as being either approved or in development, thus helping clinicians to improve the standard-of-care for patients with hemophilia. Recombinant factors still remain the standard of care in hemophilia, however they pose a challenge to treatment adherence because they have short half-life, which where the extended half-life (EHL) factors come with the solution, increasing the half-life to 96 hours. Gene therapies have a promising future with proven beneficial effects in clinical trials. We present and critically analyze in the current manuscript the pros and cons of all the major discoveries in the diagnosis and treatment of HA and HB, as well as identify key areas of hemophilia research where improvements are needed.

Abstract
FVIII and immunoglobulins (Igs) are the most prominent plasma proteins, which play a vital role in plasma hemostasis. These proteins have been implemented frequently in protein therapy. Therefore, their maintenance, durability, and stability are highly essential. Herein, various approaches to improve protein functions have been investigated, such as using recombinant protein replacement. In comparison, advances in nanotechnology have provided adequate context to boost biomaterial utilization. In this regard, the applications of various nanoparticles such as polymeric nanomaterials (PEG and PLGA), metal nanoparticles, dendrimers, and lipid based nanomaterials (liposomes and lipid nanoparticles) in stability and the functional improvement of antibodies and coagulation factor VIII (FVIII) have been reviewed from 2010 to 2020. Reviewing related articles has shown that not only can nanomaterials adequately protect the structure of proteins, but have also improved proteins' functions in some cases. For example, the high rate of FVIII instability has been successfully enhanced by bio-PEGylation. Also, utilizing PEGylated liposomes, using the PEG-lip technique for coating nanostructures, leads to FIIIV half-life prolongation. Hence, PEGylation had most impact on the stability of FVIII. Likewise, PEG-coated liposome nano-carriers also presented such a good effect on stability improvements for FVIII due to their ability to tune the immune system by reducing FVIII immunogenicity. Similarly, Ig PEGylation and conjugation to magnetic nanoparticles resulted in increased half-life and better purification of Igs, respectively, without any loss in structural or functional features. Consequently, metal-organic frameworks and recent hybrid systems have been introduced as promising nanomaterials in biomedical applications. As far as we know, this is the first study in this field, which considers the applications of nanoparticles for improving the storage and stability of antibodies and coagulation FVIII.

Abstract
BACKGROUND Research describing patient experience and outcomes with extended half-life recombinant factor VIII (EHL rFVIII) outside of clinical trials is limited. Real-world rFVIII consumption studies, when people with hemophilia A (PWHA) switch from standard half-life (SHL) to EHL rFVIII, may help payers and clinicians make more informed treatment choices. OBJECTIVE To conduct a retrospective, observational, U.S.-based analysis to describe clinical and demographic profiles of PWHA who switched to prophylactic rurioctocog alfa pegol. METHODS Data were obtained from PWHA treated by 38 prescribers across 21 states using specialty pharmacy database case report forms, electronic medical records, and direct communication with providers, PWHA, or their guardians. Assessments included disease severity, pain severity, number and location of target joints, prior HA therapy, reasons for switching, treatment duration, dosing frequency, adherence, and annualized bleeding rates (ABRs) before and after switching to rurioctocog alfa pegol from SHL or another EHL rFVIII. RESULTS Data were collected from 56 PWHA. The mean age was 26 years (range = 5-88); median age was 24 years (interquartile range = 14-34); 20% were aged < 12 years; and 89% (50/56) had severe HA. All PWHA had ≥ 12 months of rFVIII treatment before switching to rurioctocog alfa pegol. The population had a mean 1.8 target joints. Baseline subjective pain assessment was mild to moderate for 68% (38/56) of respondents. Before receiving rurioctocog alfa pegol, most PWHA received antihemophilic factor (recombinant) for prophylaxis (73%, 41/56) or breakthrough bleeding (59%, 33/56). Mean dosing frequency for prior prophylaxis was 2.8 per week for SHL rFVIII and 1.8 per week for EHL rFVIII, and 2.2 per week for all PWHA after switching to rurioctocog alfa pegol prophylaxis. The median time on rurioctocog alfa pegol prophylaxis was 12.0 months versus 80.8 months on previous SHL rFVIII and 13.5 months on previous EHL rFVIII. Mean ABRs on prior prophylaxis were 5.9 for SHL rFVIII (n = 35) and 4.7 for EHL rFVIII (n = 3). After switching to rurioctocog alfa pegol, the overall mean ABR reduced by 71% (5.8 to 1.7, P < 0.001) and 20/56 PWHA had no bleeding events. There was also a 20.9% reduction in the mean days per week of factor administration (P < 0.001) after switching to prophylactic rurioctocog alfa pegol. For 47 PWHA who switched from SHL rFVIII, their weekly dose decreased from 109.8 to 100.6 IU per kg with rurioctocog alfa pegol (P = 0.094). The proportion of PWHA with good/complete treatment adherence increased from 68% (38/56) on any prior rFVIII to 80% (45/56) on rurioctocog alfa pegol. The most common reason PWHA switched to rurioctocog alfa pegol was to reduce treatment infusions. CONCLUSIONS Switching from either an SHL or EHL rFVIII to rurioctocog alfa pegol is associated with fewer bleeding episodes owing to more effective prophylaxis and improved adherence. Those who switched from an SHL rFVIII reported reduced factor consumption with rurioctocog alfa pegol. This long-acting factor is an important additional option for the care of PWHA.

Abstract
The impact of protein therapeutics in healthcare is steadily increasing, due to advancements in the field of biotechnology and a deeper understanding of several pathologies. However, their safety and efficacy are often limited by instability, short half-life and immunogenicity. Nanodelivery systems are currently being investigated for overcoming these limitations and include covalent attachment of biocompatible polymers (PEG and other synthetic or naturally derived macromolecules) as well as protein nanoencapsulation in colloidal systems (liposomes and other lipid or polymeric nanocarriers). Such strategies have the potential to develop next-generation protein therapeutics. Herein, we review recent research progresses on these nanodelivery approaches, as well as future directions and challenges.

Abstract
The current interest in recombinant factor VIII (rFVIII) products stems from the fact that they offer a technological solution to prolonging the half-life of and reducing the risk of formation of alloantibodies (inhibitors) against FVIII in treated patients with hemophilia A (HA). The Italian health care system has authorized the use of a wide range of rFVIII concentrates of the first, second, and third generation, as well as new innovative rFVIII preparates with an extended half-life (EHL) (Kogenate FS®-Bayer, belonging to the second generation and replaced since 2017 by a product consisting of the same modified molecule; because it is only available until the end of the current year, it will not be considered in this review). Some of these products have unique pharmacodynamic and pharmacokinetic (PK) profiles, including an EHL. The first-generation full-length rFVIII (FL-rFVIII), octocog alfa (Recombinate® Baxter/BIOVIIIx), although the oldest rFVIII product, has several desirable features. Third-generation products include two modified octocog alfa molecules (Advate®, Shire; Kovaltry®, Bayer) as well as the B domain-deleted rFVIII (BDD-rFVIII) moroctocog alfa (ReFacto®-Pfizer). The B domain-truncated (BDT-rFVIII) turoctocog alfa (NovoEight®, Novo Nordisk), the BDD-rFVIII simoctocog alfa (Nuwiq®, Kedrion), the single-chain BDT-rVIII lonoctocog alfa (Afstyla®, CSL Behring), and the BDD-rFVIIIFc efmoroctocog alfa (Elocta®, Sobi-Biogen) are new, innovative products. Simoctocog alfa, because its peculiarities, is considered a fourth-generation rFVIII concentrate. Turoctocog alfa, simoctocog alfa, and lonoctocog alfa have a high affinity for von Willebrand factor (vWF) that reduces renal clearance and prolongs the half-life of rFVIII. Efmoroctocog alfa, a first-in-class rFVIII-Fc fusion protein (rFVIIIFc), has a half-life 1.5–1.8 times longer than that of conventional plasma-derived FVIII (pd-rFVIII) and other rFVIII products. Clinical studies have evaluated the efficacy, safety, and inhibitor development of all these innovative concentrates in both previously treated (PTPs) and untreated patients (PUPs). This review considers the rFVIII products that are indicated for the treatment of patients with severe HA, focusing on those that are commercially available in Italy. Their PK characteristics, immunogenicity, and clinical benefits are discussed and compared.

Abstract
Despite effective factor replacement and various treatment schedules, there remain several challenges and unmet needs in the prophylactic treatment of hemophilia limiting its adoption and thereby posing an increased risk of spontaneous bleeding. In this regard, extended half-life (EHL) recombinant factor VIII (rFVIII) and factor IX (rFIX) products promise optimal prophylaxis by decreasing the dose frequency, increasing the compliance, and improving the quality of life without compromising safety and efficacy. EHL products might lead to higher trough levels without increasing infusion frequency, or could facilitate the ability to maintain trough levels while reducing infusion frequency. This paper aims to provide a comprehensive review of the rationale for developing EHL coagulation factors and their utility in the management of hemophilia, with special emphasis on optimal techniques for half-life extension and criteria for defining EHL coagulation factors, as well as indications, efficacy, and safety issues of the currently available EHL-rFVIII and EHL-rFIX products. Potential impacts of these factors on quality of life, health economics, and immune tolerance treatment will also be discussed alongside the challenges in pharmacokinetic-driven prophylaxis and difficulties in monitoring the EHL products with laboratory assays.

Abstract
Poor understanding of the pathophysiological mechanisms involved in Haemophilia is a major obstacle in accessing effective haemophilia disease management. Haemophilia is a life-frightening bleeding problem in which there are repeated bleeding episodes. Various approaches have been used, involves clotting factor replacement therapy for effective bleeding control in Haemophilia. Current advancements in the management of patients with haemophilia include altered pharmacokinetics clotting factor concentrates for better prophylaxis and management of haemophilia. This review sums up the prophylactic treatment, novel production techniques, other treatment techniques and the present position of gene therapy in the treatment of haemophilia.

Abstract
Peptides often suffer from short in vivo half-lives due to proteolysis and renal clearance that limit their therapeutic potential in many indications, necessitating pharmacokinetic (PK) enhancement. d-Peptides, composed of mirror-image d-amino acids, overcome proteolytic degradation but are still vulnerable to renal filtration due to their small size. If renal filtration could be slowed, d-peptides would be promising therapeutic agents for infrequent dosing, such as in extended-release depots. Here, we tether a diverse set of PK-enhancing cargoes to our potent, protease-resistant d-peptide HIV entry inhibitor, PIE12-trimer. This inhibitor panel provides an opportunity to evaluate the PK impact of the cargoes independently of proteolysis. While all the PK-enhancing strategies (PEGylation, acylation, alkylation, and cholesterol conjugation) improved in vivo half-life, cholesterol conjugation of PIE12-trimer dramatically improves both antiviral potency and half-life in rats, making it our lead anti-HIV drug candidate. We designed its chemical synthesis for large-scale production (CPT31) and demonstrated that the PK profile in cynomolgous monkeys supports future development of monthly or less frequent depot dosing in humans. CPT31 could address an urgent need in both HIV prevention and treatment.

Abstract
INTRODUCTION Hemophilia A is the most frequent inherited bleeding disorder and most challenging coagulation disorder. To combat this, a number of new improved rFVIII/IX concentrates have recently been approved. Some of them are derived from protein fusion biotechnology or pegylation to extend their half-life (HL). However, prophylaxis has become a standard of care to prevent arthropathy in hemophiliacs though the need of frequent venipunctures is a major obstacle to primary prophylaxis. The new Extended Half-Life (EHL) rFIX concentrates allow increased intervals, while the improved HL of new rFVIII was moderate. rFVIII Simoctocog alfa is produced in Human Embryonic Kidney (HEK) cells and the post-translational modifications performed by HEK cells are very similar to those occurring in the native FVIII. Areas covered: Herein, the author provides a review of simoctocog alfa with its contents including information on simoctocog alfa's manufacturing, clinical trials, safety and tolerability. They also give their expert opinion and future perspectives on this therapy. Expert opinion: An important advantage of simoctocog alfa is the possibility to omit at least 30% of venipunctures with prophylaxis. Consequently, the standard three times weekly bolus administrations may be reduced to twice weekly, meaning approximately 50 fewer venipunctures per year. This may be particularly helpful to children.

Abstract
Hemophilia A (HA) is a common bleeding disorder caused by the deficiency of factor VIII (FVIII) with an incidence of ~1 in 5000 male births. Replacement of FVIII is necessary to prevent and treat bleeding episodes. However, with multiple new drugs in addition to old standards, choosing among the different FVIII treatment options is harder than ever. There are FVIII products that are plasma derived or recombinant, FVIII products designed to extend the half-life of FVIII, and the first single-chain FVIII product, recombinant factor VIII single chain (rFVIII-SC). As development of inhibitors to FVIII continues to be a major problem in the care of HA patients, recent studies showing lower rates of inhibitor development with plasma-derived FVIIII products versus recombinant FVIII products have made choosing among the many options now available even more complex. Although still unproven, extended half-life (EHL) products may provide the hope of decreased immunogenicity but need further testing in previously untreated patients (PUPs). This review highlights some of the differences between FVIII products currently available and hopefully assists the clinician to decide which FVIII product to choose for their patients.
