Filter by:Background. The recurrence of hemarthrosis in patients with congenital coagulopathies favors the development of a progressive, degenerative intra-articular lesion (hemophilic arthropathy) that mainly affects the knees, ankles and elbows. Disability and functional limitations are characteristic sequelae of these patients from an early age. Objective. To assess the joint status, the perception of quality of life, the performance of roles and the performance of daily life activities, in patients with hemophilic arthropathy. Study design. Observational, multicenter study. Method. 70 patients with hemophilia A and B will be included in this study. Patients will be recruited from 4 centers in different regions of Spain. The dependent variables will be: pain (measured with the Visual Analogue Scale), joint status (Hemophilia Joint Health Score), perception of quality of life (SF-36 questionnaire), list of roles, performance of daily life activities (Barthel scale), performing the instrumental activities of daily life (Lawton and Brody scale). The evolution of the variables will be analyzed using parametric (t-student or ANOVA) or non-parametric (Wilcoxon or Friedman) tests. A correlation analysis will be carried out between the dependent and independent variables, as well as a linear regression analysis between the observed determining variables. Expected results. The aim is to observe the relationship of pain and joint status in patients with hemophilic arthropathy, with their perception of quality of life, the development of the roles they play and the performance of basic and instrumental activities of daily living.
Record real life data of patients with Hemophilia A and treated with Afstyla® to assess the effectiveness and the safety of the treatment used as prophylaxis, prevention of bleeding (e.g. surgery) or on-demand treatment during 3 years after patient inclusion
Primary Objective: - To evaluate the long-term safety of BIVV001 in previously treated subjects with hemophilia A Secondary Objectives: - To evaluate the efficacy of BIVV001 as a prophylaxis treatment. - To evaluate the efficacy of BIVV001 in the treatment of bleeding episodes. - To evaluate BIVV001 consumption for prevention and treatment of bleeding episodes. - To evaluate the effect of BIVV001 prophylaxis on joint health outcomes. - To evaluate the effect of BIVV001 prophylaxis on Quality of Life (QoL) outcomes. - To evaluate the safety and tolerability of BIVV001 treatment. - To assess the PK of BIVV001 based on the one stage activated partial thromboplastin time (aPTT) and two-stage chromogenic FVIII activity assays (only applicable to Arm B). - To evaluate the efficacy of BIVV001 for perioperative management
Long-term follow-up of subjects who received SB-318, SB-913, or SB-FIX in a previous trial and completed at least 52 weeks post-infusion follow-up in their primary protocol. Enrolled subjects will be followed for a total of up to 10 years following exposure to SB-318, SB-913, or SB-FIX.
This study will enroll children who have hemophilia A with inhibitors who successfully completed immune tolerance induction per the ISTH criteria (negative inhibitor titer, recovery >66% of expected, and half-life of >6 hours with their current FVIII concentrate). Previous to emicizumab, there was only one option for these patients which was to continue FVIII therapy in a prophylaxis mode to prevent bleeding. There was a sense that the ongoing FVIII served to maintain tolerance however no evidence for this notion exists and in fact what limited data is available suggests that continuing FVIII may not be necessary simply to maintain tolerance. To figure out this question, this will be a randomized, controlled 2 arm study which will randomize patients post-successful ITI to emicizumab plus weekly FVIII (for maintenance of tolerance) versus emicizumab alone. Patients will be followed for up to 2 years. We aim to enroll 52 subjects. The FVIII weekly arm can use any factor VIII concentrate and emicizumab is standard of care for inhibitor and non-inhibitor patients.
In this observational study researchers want to learn more about the safety of drug Jivi over a long period of time. Jivi (generic name: Damoctocog alfa pegol) is an approved blood clotting Factor VIII (FVIII) medication for the treatment of hemophilia A (bleeding disorder resulting from a lack of FVIII). It is manufactured via recombinant technology and has an extended half-live, i.e. it will stay longer in the body than other FVIII products. Therefore Jivi acts longer in the body which reduces the frequency of drug injections. This study will enroll previously treated patients with hemophilia A who are receiving Jivi regularly at their treating doctors to prevent bleeding. Observation for each patient will last for at least 4 years, and medical data will be collected during patients' routine visits at their treating doctors.
This is a Phase IIIb, multicenter, open-label, single-arm study of prophylactic emicizumab in previously untreated and minimally treated patients at study enrollment from birth to ≤12 months of age with severe hemophilia A (intrinsic factor VIII [FVIII] level <1%) without FVIII inhibitors. The study is designed to evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of emicizumab administered at 3 milligrams per kilogram of body weight (mg/kg) once every 2 weeks (Q2W) for 52 weeks. After 1 year of treatment, participants will continue to receive emicizumab (1.5 mg/kg once every week [QW], 3 mg/kg Q2W or 6 mg/kg once every 4 weeks [Q4W]) over a 7-year long-term follow-up period under this study frame.
C3731003 is a pivotal Phase 3 study to evaluate the clinical efficacy and safety of a single IV infusion of PF-07055480 / giroctocogene fitelparvovec (Recombinant AAV2/6 Human Factor VIII Gene Therapy) in adult male participants with moderately severe or severe hemophilia A (FVIII:C≤1%) for the study duration of 5 years. The study will enroll eligible participants who have been followed on routine prophylaxis with FVIII products in the Lead-In study C0371004.
This Phase III clinical study will evaluate the safety and effectiveness of valoctocogene roxaparvovec in combination with prophylactic corticosteroids in patients with severe hemophilia A.
This is a 48-month observational, prospective, multicentre study. The overall aim of the study is to evaluate the long-term effectiveness of Elocta treatment on joint health in patients treated prophylactically with Elocta in a real-world setting.
