83 Clinical Trials for Various Conditions
This is an interventional, prospective, international, multicenter, single-arm, Phase 3, and sequential efficacy and safety study in adolescents and adults with congenital hemophilia A or B with inhibitors to factor VIII (FVIII) or factor IX (FIX) undergoing elective major surgical procedures.
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.
Hemophilia A (HA) is a genetic bleeding disorder resulting from a deficiency or absence of factor VIII (FVIII), which is necessary in the clotting process. This disorder occurs mostly in males and in severe cases causes frequent bleeding episodes in joints and muscles which can lead to progressive damage that affects mobility and quality of life. Prophylactic FVIII administered intravenously every other day has been the standard of care treatment for HA for the past few decades. Sports and physical activity are generally encouraged in patients with hemophilia on appropriate prophylactic treatment to increase strength, prevent or decrease obesity, accrue and maintain bone density and encourage normal socialization. To ensure safety with participation in sports in persons with hemophilia A (PWHA), timing of FVIII administration is often adjusted to maximize FVIII at the time of sports. The exact factor level that is needed to safely participate in sports and minimize bleeding risk is not yet known. Based on clinical practice, infusion of FVIII to near the lower limit of normal right before participation in sports generally works to prevent bleeding. The study is looking at how well the newly approved medication Emicizumab works compared to Factor VIII to prevent bleeding in patients with Hemophilia A who play sports. The study will enroll children and adolescents who are already on Emicizumab or Factor VIII who are currently playing sports.

The investigators propose to study longitudinal joint and bone density changes in patients with severe Hemophilia A. Per current standard of care, most patients are on prophylactic FVIII replacement therapy intravenously several times weekly with a goal of keeping the trough \>1% FVIII. Recent phase 3 data suggest superior bleed protection with emicizumab prophylaxis every 1-2 weeks. It is the purpose of this study to longitudinally assess joint health and bone density over 3 years and to compare the effect of routine factor VIII prophylaxis with emicizumab prophylaxis.
Multiple sclerosis (MS) patients hospitalized with an acute motor or visual relapse will be consented. Factor VIII-related labs will be systematically drawn for six months. During this time, patients will be followed with clinical assessments including: Expanded Disability Status Scale (EDSS), Multiple Sclerosis Functional Composite (MSFC), Low Contrast Sloan Letter Chart Testing, Symbol Digital Modality Test (SDMT), and NeuroQol. MRIs of the brain, cervical spine, and thoracic spine with and without contrast will be obtained. All patients will be treated with 1 gram IV solumedrol daily for five days per standard care. Clinical, imaging, and Factor VIII-related lab data individually or in aggregate will be correlated with relapse presence, severity, and extent of recovery following standard intravenous (IV) solumedrol treatment
This is a Phase I study. This research study is being conducted to find new ways to treat severe hemophilia A. This study is a gene therapy study. Gene therapy is an experimental way to introduce, into a person's cells, specific genetic material. A gene can be delivered/introduced into a cell using a carrier known as a "vector." In this study, a virus (lentivirus), the "vector", is used to introduce or deliver a gene that creates and stores a protein Factor VIII (FVIII) in your platelets. These platelets are made from stem cells (mother cells for your bone marrow) that are removed from your blood by a procedure called apheresis. This research study will take some of the patient's own stem cells, from the apheresis procedure, and genetically modify them using the vector in order to make them produce FVIII in platelets that arise from the stem cells. They will then give the genetically modified stem cells back to the patient so that they can possibly create platelets that produce and store Factor VIII on their own.
Primary Objective: To characterize the long-term safety and tolerability of fitusiran Secondary Objectives: * To characterize the efficacy and long-term efficacy of fitusiran as assessed by the frequency of: * Bleeding episodes * Spontaneous bleeding episodes * Joint bleeding episodes * To characterize the effects of fitusiran on health-related quality of life (HRQOL) measures in participants ≥17 years of age
In this study researchers want to gather more information about safety and effectiveness of BAY 2599023 (DTX201), a drug therapy that delivers the human factor VIII gene into the human body by use of a viral vector to treat the disease. By replacing the defective gene with a healthy copy the human body may produce clotting factor on its own. Hemophilia A is a bleeding disorder in which the human body does not have enough clotting factor VIII, a protein that controls bleeding. Researcher want to find the optimal dose of BAY 2599023 (DTX201) so that the body may produce enough clotting factor on its own.
This study will look at how a known study medicine N8-GP works in previously N8-GP treated people with haemophilia A. The aim is to look at how N8-GP works during regular use. Participants will get N8-GP. N8-GP has been tested in more than 200 people with haemophilia A for several years. Participants will get an injection of N8-GP into a blood vessel, one, two or three times weekly. Participants will get more doses if they bleed or if they will need a surgery. The study will last for about 2 years. Participants will have at least 9 visits with the study doctor. If participants agree to be in this study, they will get their first injection (in this study) at the first visit. Participants will also get an injection at visit 3, 5 and 7. Participants will be trained to give all other injections themselves. Participants must not use any clotting factors other than N8-GP or any anticoagulants (blood thinners) during the study.
This US study will assess hemophilia A patient characteristics, health history and reasons for switching or not switching from both patient/caregiver and physician perspectives. For this purpose, this research study will include hemophilia A: 1) patients who have switched from conventional therapy to new FVIII products with an improved PK profile. 2) patients who remain on conventional therapy (who have never switched) but have considered switching, including those patients who switched from conventional therapy to new FVIII products with improved pharmacokinetics and then subsequently "switched back" to conventional replacement therapy. In doing so, real world evidence will be obtained from both patient and physician perspectives offering key insights for effective therapeutic management of patients with hemophilia A and to more fully understand what drives patient switching from a patient perspective and a physician perspective.
The primary purpose was to assess the safety and tolerability of a single intravenous (IV) administration of BIVV001 in adult previously treated patients (PTPs) with severe hemophilia A.
This non-randomized, multicenter, open-label, Phase III clinical study will evaluate the efficacy, safety, and pharmacokinetics of emicizumab administered subcutaneously initially once weekly (QW) in pediatric participants with hemophilia A with FVIII inhibitors. This study will open two additional non-randomized cohorts to investigate once every 2 weeks (Q2W) and once every 4 weeks (Q4W) regimens in pediatric participants.
Commercial one and two-stage factor VIII assays may not detect some clinically significant inhibitor antibodies. The purpose of the proposed study is to standardize and validate a platelet-based factor VIII activity assay with greater sensitivity to clinically important inhibitory antibodies. Investigators will evaluate the platelet-dependent inhibitory activity vs. conventional inhibitory activity in stored patient plasmas and correlate to bleeding histories
This study is for young children with severe hemophilia A who have previously not been treated with BAX855 or other FVIII concentrates. The main aim of the study is to check for side effects from treatment with BAX855. This includes the buildup of antibodies against FVIII which may stop BAX855 from working properly. Another aim is to learn how well BAX855 controls bleeding. In this study, the children can receive BAX855 either as preventative treatment (prophylaxis), or as needed to treat bleeding (on-demand). In case a participant develops antibodies, treatment will be provided as part of the study.
The primary objective of the study was to evaluate the safety of rFVIIIFc (BIIB031) in previously untreated participants (PUPs) with severe hemophilia A. The secondary objectives were to evaluate the efficacy of rFVIIIFc in the prevention and treatment of bleeding episodes in PUPs, to evaluate rFVIIIFc consumption for the prevention and treatment of bleeding episodes in PUPs, and to describe experience with the use of rFVIIIFc for immune tolerance induction (ITI) in participants with inhibitors.
This is an international, multicenter, open-label study to assess the efficacy, safety, and pharmacokinetic (PK) profile of rVIII-SingleChain in pediatric patients with severe hemophilia A. A minimum of 25 previously treated subjects ≥ 6 to \< 12 years of age and at least 25 subjects \< 6 years of age who have undergone \> 50 exposure days (EDs) with a previous Factor VIII (FVIII) product are planned to be enrolled. Subjects will be assigned to either an on-demand or prophylaxis treatment regimen and will receive rVIII-SingleChain at a dose to be determined by the investigator. Hemostatic efficacy will be assessed by the subject/caregiver and the investigator who will assess overall efficacy by a 4-point scale.
