Filter by:Factor VIII (FVIII) is a large plasma glycoprotein that participates in blood coagulation. Loss of circulating FVIII activity due to mutations within the F8 gene results in the X-linked, recessive bleeding disorder hemophilia A. The clinical presentation ranges from a mild to severe bleeding phenotype that correlates with the patient's residual plasma FVIII activity level. Current state of the art treatment entails frequent infusion of FVIII protein. However, several limitations remain to treating hemophilia A, which are 1) access to FVIII-replacement products (currently <30% of the world population is treated adequately, access is highly restricted in India), 2) high burden of compliance with treatment protocols particularly in children 3) the expense of FVIII-replacement products, 4) the development of humoral anti-FVIII immune responses that block FVIII activity and limit treatment efficacy and 5) morbidity due to crippling musculoskeletal disease when inadequately treated. Several newer hemostasis agents are being developed but like the recombinant Clotting Factor Concentrate (CFC) from the 1990s, these are also not likely to be made available in India for many years. Currently, the only cure for hemophilia A is orthotopic liver transplantation.

We have developed a questionnaire to elucidate the dosing, frequency and indication for the use of emicizumab in patients with Hemophilia A (mild, moderate or severe) ages 0-3 years. We are also collecting data on any pre-, peri and post surgical practices while on emicizumab. More importantly, we are asking if pediatricians are planning to introduce factor 8 to children who are already on emicizumab for primary prophylaxis as well as how and when they are planning to do so. We hope that this data will help inform understanding of current use of emicizumab in infants and young children as a form of primary prophylaxis, especially when venous access has historically been a limiting factor.
Background: Elderly people with serious haemophilia (PwSH), i.e., with moderate or severe haemophilia, have major comorbidities due to consequences of haemophilia. Also, the comorbidities related to age are added. Despite the existence of numerous studies on the objective health status of elderly PwSH, some limitations may be stated (need to update the results in a more contemporary context, no studies conducted in France, highlighted determinants focused on demographic and clinical factors). On the contrary, the perceived health status of elderly PwSH has been little described. Only two studies specifically addressed the quality of life (QoL) of elderly PwSH. These studies reported an altered QoL in some domains, in comparison with reference values from the general population. However, some limitations may also be stated (need to bring results in a more contemporary context, no studies conducted in France, highlighted determinants focused on clinical factors). Since serious haemophilia is a rare disease, studies are often performed on a small number of subjects. The present project relies on the FranceCoag registry, a unique exhaustive national cohort of PwSH followed over time among whom 612 are elderly PwSH. Objectives: Main objective: to describe the objective and perceived health status of elderly (≥60 y.o.) PwSH from of a French exhaustive national registry, and to compare their health status with that of the French general elderly population. Secondary objective: to identify individual (demographic, clinical, social, psycho-cognitive) and collective characteristics (related to healthcare organisation), associated with the objective and perceived health status of elderly PwSH in France. Materials and Methods: A national, multicentric, observational, cross-sectional study will be conducted. It will be based on the participation of elderly PwSH already included in the FranceCoag registry. Each eligible participant will receive a questionnaire to complete concerning: objective health status; perceived health status (QoL assessed by the WHOQOL-Old questionnaire); demographic data; social data; psycho-cognitive data (anxious symptoms, depressive symptoms, use of coping strategies, time perspective). Therapeutic and clinical data related to haemophilia will be collected via the FranceCoag registry database. Data concerning healthcare organisation will be collected directly from investigators of Haemophilia Treatment Centres. The main analysis will consist in the description and comparison of the health status with reference data from the French general elderly population. Standardisation methods will be used to take into account a potential imbalance between the study population and the reference population, related to age and especially to sex, as haemophilia is a predominantly male disease. The secondary analysis will consist in the identification of potential determinants of the health status. Structural equation models will be performed to take into account the complexity of the relationships between the determinants. Impact of the proposal Better understanding the impact of the disease on patients' experience is essential in a systematic global perspective of health, that aims to care and support the individual not only as a patient but also as a person in his/her environment. This study based on a registry will allow to improve the knowledge by updating literature data on the health status of elderly PwSH, adding elements to the rare literature data on the perceived health status, providing data in the French specific context, and identifying both classical and more original determinants of health status of elderly PwSH. These results will be used to better identify elderly PwSH at high risk of poor health status, to propose recommendations and to set up actions to offer them an adapted support, and to elaborate new versions of public health plans dedicated to haemophilia or to rare diseases.
This study aims to develop a systematic genetic screening strategy for (potential) female carriers of haemophilia by identifying as many female carriers as possible within the families of haemophilia patients regularly followed at Cliniques universitaires Saint-Luc (CUSL) and to search for differences between female carriers of haemophilia A (HA) and B (HB).
This is a multi-center, single-arm, open-label, single-dose treatment clinical study to evaluate the safety, tolerability and efficacy of BBM-H901 injection in Hemophilia B subjects with ≤2 International unit per deciliter (IU/dl) residual factor IX (FIX) levels. BBM-H901 is an adeno-associated virus (AAV) vector derived from recombinant DNA techniques to contain an expression cassette of the human factor IX (hFIX) transgene and raises circulating levels of endogenous FIX.
Hemophilia (A and B) are X-linked hereditary bleeding disorders whose severity depends on the level of coagulation factor (FVIII or FIX respectively). Bleeding is mainly from joints (hemarthrosis) and muscles (hematoma). Nowadays, treatment is based on preventive or curative intravenous infusion of coagulation factor concentrates. Despite these treatments, there is joint deterioration that can be responsible for hemophilic arthropathy and chronic pain. This pain may be related to excess nociception during acute bleeding, but it may also be neuropathic. There are only a few studies that have looked at pain in hemophilia, but it is accepted that the vast majority of patients (especially those with severe forms) suffer from chronic pain. Because patients have become accustomed to this pain and physicians are still not very aware of how to assess it, this pain is not treated effectively. In order to better manage pain in hemophilia, it is therefore necessary to characterize their pain and to know the nociceptive or neuropathic component. The aim of our study is therefore to study the prevalence, the nociceptive or neuropathic profile, the chronic aspect of pain and the main locations of pain in hemophilia. In addition to raising the awareness of physicians in the centers about pain management using specific questionnaires, this survey will help to better define chronic pain in hemophilia of all severities.
Hemophilia is a constitutional coagulation disorder responsible for a hemorrhagic phenotype in patients from an early age. Hemarthrosis is one of the most frequent complications in hemophiliacs and leads to the development of severe and early arthropathy, sometimes as early as childhood. To date, there is no curative treatment for these joint disorders and preventive treatments are insufficient to completely prevent joint degradation. Mesenchymal stem cells have been shown to be of therapeutic interest in the management of pathologies such as osteoarthritis and inflammatory arthritis through their anti-inflammatory, regenerative and anti-apoptotic effects. Hemophilic arthropathy is a separate condition at the border of these two diseases Our study aim to show pre-clinical interest of mesenchymal stem cell therapy in hemophilic arthropathy
Study MO42623 is a Phase IV, multicenter, open-label, three cohort study designed to evaluate the impact of emicizumab prophylaxis on overall health, physical activity, and joint outcomes in participants aged ≥13 and <70 years with severe hemophilia A without factor VIII (FVIII) inhibitors or moderate hemophilia A without FVIII inhibitors who are receiving FVIII prophylaxis and who will start emicizumab treatment as part of this study.
