Filter by:The study investigates how well the medicine called turoctocog alfa pegol (N8-GP) works in previously treated Chinese patients with severe haemophilia A. Participants will be treated with N8-GP. This is a medicine that doctors can already prescribe in other countries. The medicine will be injected into a vein (intravenous injections) and blood samples will be collected. The study will last for about 7-8 months. Participants will have between 8 and 15 visits to the clinic and possibly a number of phone calls with the study doctor.
This study is investigating how Mim8 works compared to other medicines in people with haemophilia A, who either have inhibitors or do not have inhibitors. Mim8 is a new medicine that will be used for prevention of bleeding episodes. Mim8 works by replacing the function of the missing clotting factor VIII (FVIII). When and how often participants will receive Mim8 is dependent on their previous treatment - but is otherwise decided by chance. Mim8 will be injected into a skinfold on the stomach with a thin needle either once a week or once a month. The study will last 54-124 weeks (12-29 months) depending on how long participants will be followed in run-in before they start treatment and if they continue in the follow period or transfer to an open label extension study. Participants will have 12-17 clinic visits.
Gene therapy is a paradigm-shifting treatment for hemophilia B patients, particularly in resource-limited countries where factor availability remains low. Transparent and culturally sensitive communication around gene therapy is vital to the success of a high-quality consenting process. Current literature on knowledge, beliefs and attitudes about gene therapy in resource-limited countries is inadequate. In addition, few educational resources to explain basic gene therapy concepts exist in languages other than English. This study aims to address these gaps in knowledge and aid for the development of educational resources to assist the informed consent processes for gene therapy in resource-limited countries. Primary Objective: To assess baseline knowledge, beliefs, and attitudes about gene therapy held by hemophilia B patients globally Secondary Objectives: 1. To explore healthcare workers' (i.e., physicians, nurses, social workers, educators/academic coordinators) perspectives regarding the education needs of hemophilia B patients globally 2. To explore healthcare workers beliefs and attitudes about gene therapy 3. To identify preferences of patients with hemophilia B and their healthcare workers on how/by what method or pathway educational content should be provided.
Primary objective • To assess the half-life of BIVV001, Standard Half-Life (SHL) rFVIII and Extended Half-Life (EHL) rFVIII after a single intravenous (IV) injection Secondary objectives - To characterize additional pharmacokinetic (PK) parameters of BIVV001, SHL rFVIII and EHL rFVIII after a single IV injection - To evaluate the safety and tolerability of a single IV injection of BIVV001
Researchers are looking for a better way to treat people who have hemophilia A. Hemophilia A is a genetic bleeding disorder that is caused by the lack of a protein in the blood called "clotting factor 8" (FVIII). FVIII is naturally found in the blood where it causes the blood to clump together to help prevent and stop bleeding. People with lower levels of FVIII or with FVIII that does not work properly may bleed for a long time from minor wounds, have painful bleeding into joints, or have internal bleeding. The study treatment, Jivi (also called damoctocog alfa pegol), is already available for doctors to prescribe to people with hemophilia A to treat and prevent bleeding. It works by replacing the missing FVIII, or the FVIII that does not work properly. People with hemophilia A need frequent injections of FVIII products into the vein. So called standard half-life (SHL) products need to be given 2 to 4 times a week for the prevention of bleeding. In recent years, new products like Jivi called extended half-life (EHL) products have become available. These products last longer in the body so that they require to be given less often with injections every 3-5 days. Thus, these treatments may be easier and more comfortable to stick to in daily life. There is no general plan concerning the best amount of treatment and the frequency of injections for the prevention of bleeding, since the severity may be different and individual risk factors have to be considered. Doctors often decide on a treatment plan based on their experience. The main purpose of this study is to learn how well a new scoring approach works to select a treatment plan for the prevention of bleeding in people with hemophilia A who switch their treatment from SHL products to Jivi. Different types of information are used to calculate the risk score like bleeding history, certain biological factors, and physical activity of the participant. All participants will receive Jivi for 6 months. In the first four weeks, all participants will receive Jivi 2 times a week at a dose level of 40 IU per kilogram body weight (also known as 40 IU/kg/dose, recommended maximum dose is 6,000 IU). Then, based on their risk score, each participant will be assigned to one of three treatment plans: - participants with a high risk remain on Jivi administration 2 times a week at 40 IU/kg/dose - participants with a medium risk will switch to Jivi administration every 5 days at 50 IU/kg/dose - participants with a low risk will switch to Jivi administration every 5 days at 50 IU/kg/dose and after 4 weeks to a less frequent administration (e.g., every 7 days) at 60 IU/kg/dose To check how well the new scoring approach works for choosing the right treatment plan, researchers will look at how many participants have a favourable outcome. This means that the participant has either fewer bleeding events vs. the pre-study treatment and takes Jivi less often or as often as the previous SHL treatment but with fewer bleeding events, or that the participant has a comparable number of bleeding events but needs to take Jivi less often than the previous treatment. Each participant will be in the study for approximately 7.5 months. During this time, 4 visits to the study site and 3 phone calls are planned. During the study, the doctors and their study team will: • do physical examinations • take blood samples • ask the participants questions about how they are feeling and what adverse events they are having. In addition, participants or their guardians are required to write down the dates of Jivi treatments and bleeding events in an electronic diary and to fill in different questionnaires on their quality of life, health status, work/ school productivity, pain, and treatment satisfaction. In addition, participants are expected to keep appointments for visits and to adhere to the assigned treatment regimen. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
This study will assess the safety and efficacy of multiple-dose of STSP-0601 for the treatment of bleeding episodes in hemophilia A or B patients with inhibitors.
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 main aim of this study is to learn more about side effects of Advate when given as standard treatment to people with hemophilia A who have already been treated. The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study. Participants will need to visit the study doctor 5 times in total during the study. During these visits, study data will be collected by the study doctor.
The main aim of this study is to learn about changes in the lowest blood levels of Factor VIII in men and boys when upgraded from standard prophylaxis with Advate to individualized prophylaxis with Advate. No study medicines will be provided to participants in this study. The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study. Participants will need to visit the study doctor 3 times in total during the study. During these visits, study data will be collected by the study doctor.
This study is about a factor VIII medicine called Adynovate (TAK-660) used during surgery for people with hemophilia A who have low blood levels of factor VIII. The aims of this study are as follows: - To check for side effects from TAK-660. - To check how well TAK-660 controls bleeding when used routinely during surgery and other invasive procedures such as tooth extractions. The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. During the study, participants will receive infusions of TAK-660 during their hospital stay for surgery according to their clinic's standard practice. The study doctors will check for bleeds and side effects from TAK-660 from surgery until discharge.
