A Study to Learn How Safe the Study Treatment BAY94-9027 is and How it Affects the Body in Previously Treated Children Aged 7 to Less Than 12 Years With Severe Hemophilia A, a Genetic Bleeding Disorder That is Caused by the Lack of a Protein Called Clotting Factor 8 (FVIII) in the Blood

Researchers are looking for a better way to treat hemophilia A. Hemophilia A is a genetic disorder where the body does not create enough of a protein called clotting factor 8 (FVIII) present in the blood. People with hemophilia A may bleed for a long time from minor wounds, have painful bleeding into joints, or have internal bleeding. In severe hemophilia A (clotting factor 8 levels less than 1%) bleedings are more likely to happen. In this study researchers want to learn more about the treatment called BAY94-9027. BAY94-9027 is an injectable medicine used to replace missing clotting factor 8. In BAY94-9027 the clotting factor 8 has been pegylated (combined with a substance called polyethylene glycol (PEG)). This is to make the treatment last longer in the body so that less injections are required. BAY94-9027 is already available for the prevention and treatment of bleeding in adults and children who are 12 years and older. BAY 94-9027 is also called Jivi. BAY94-9027 is not yet available for children aged 7 to less than 12 years. One potential specific risk of pegylated drugs is that proteins in the blood called antibodies are built. These may attach to the pegylation part of the drug and this in turn may lead to allergic reactions and the drug not working as well as it should during first 4 infusions. In studies that have been done so far, this has been seen in some children younger than six years, but not in 29 children aged 6 to less than 12 years treated with BAY94-9027. Further safety information related to how the body reacts to BAY94-9027 is however still needed for this age group. The main purpose of this study is to learn how safe BAY94-9027 is (safety) and how it affects the body (tolerability) in previously treated children with severe hemophilia A who are between 7 to less than 12 years. To answer this question, the researchers will study information about two medical problems of special interest, if allergic reactions occur (also called hypersensitivity) and if the drug is not working as well as it should (also called loss of efficacy) during the first 4 infusions. Allergic reactions may range from mild local reactions to widespread effects such as shortness of breath, skin rashes and low blood pressure. Only allergic reactions related to the study treatment will be considered. The assessment if loss of efficacy occurred will be based on the occurrence of bleeding, the clotting factor 8 level in blood after injection called recovery, clotting factor 8 inhibitor tests and measurement of antibodies against the PEG. The study has two parts, A and B. Part A takes 6 months and part B takes 18 months. In part A the participants will receive two injections of BAY94-9027 per week. In part B, the number of injections may be decreased, with up to five days between the injections. The participants in this study will visit the study site around 14 times and will have 15 phone visits. In part A, visit 1 is for screening. Visits 2 to 5 take place twice a week for two weeks. Visit 6 two weeks after visit 5, visits 7 to 10 take place monthly with visit 11 six weeks after visit 10. In part B, site visits will occur on month 9, 12, 18 and 24 and phone calls every month between the site visits. The participants' and their caregivers will record in an electronic patient diary information about when the study treatment was given and bleeding episodes that have happened. During the study, the study doctors and their team will * take blood samples, * do physical examinations, * review the participants' electronic diary * ask questions about the participants' quality of life, * ask the participants questions about how they are feeling and what adverse events they are having An adverse event is a medical problem that happens during the study. Doctors keep track of all adverse events that happen in study, even if they do not think the adverse events might be related to the study treatments.

An Observational Study Called JOIHA to Learn More About How Well the Treatment With Jivi Works to Prevent Problems With Joints in Adults With Hemophilia A.

This is an observational study in which data from people with hemophilia A who decide on their own or by recommendation of their doctors to take Jivi are collected and studied. In observational studies, only observations are made without specified advice or interventions. 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 available. These products last longer in the body so that they require to be given less often with injections up to every 7 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 patient's disease and response. Clinical studies have already shown that people with hemophilia A benefit from the treatment with Jivi. However, there are no data available coming from the real-world about how well Jivi works to support joint health, measured by ultrasound (US) examination and HEAD-US score. In this study, researchers want to learn more about how well Jivi works if used for prolonged periods of treatment under real-world settings to prevent problems with joints in people with hemophilia A. How well it works means to find out if participants' joints status can be improved by treatment with Jivi. To do this, researchers will collect data about participants' joints status by * making images of participants' joints by using sound waves (ultrasound), and * using HEAD-US score after 24 months of treatment with Jivi. The researchers will then compare these data to the participants' joints status before treatment start with Jivi. Besides this data collection, no further tests or examinations are planned in this study. Some participants in this study will already be receiving treatment with Jivi as part of their regular care no more than 12 months. And some participants will start to take Jivi in this study as prescribed by their doctors during routine practice according to the approved product information. The researchers will collect data from each patient for a period of 26 months after initiation of the Jivi treatment. There are no required visits or tests in this study

A Study to Learn More About the Safety of Damoctocog-alfa-pegol When Used in Routine Medical Care in Korean Participants With Hemophilia A

In this study, researchers will observe and study the data from participants with hemophilia A who receive damoctocog alfa pegol as prescribed by their doctors. Participants will not receive any advice or changes to their healthcare during the study. Hemophilia A is a genetic bleeding disorder. It is caused by the lack of a protein called clotting factor 8 (FVIII) that helps blood to clot properly. Lack of FVIII can result in excessive blood loss or bleeding inside the body after being injured or having surgery. The study drug, damoctocog alfa pegol, can be used to prevent or treat bleeding episodes by replacing missing FVIII in the body of people with hemophilia A. It is already approved for people with hemophilia A who are at least 12 years old and have previously used other hemophilia A treatments. Through this study, researchers want to learn more about its safety in a real-world setting. The participants will receive damoctocog alfa pegol as prescribed by their doctors during routine practice according to the approved product information. The main purpose of this study is to learn more about how safe damoctocog alfa pegol is in Korean participants with hemophilia A who previously used other hemophilia A treatments. To do this, researchers will collect information about any medical problems participants have during their treatment. Data will be collected from December 2023 to March 2026 and cover a period of about 8 months for each participant. Data will come from participants' health records and information collected during their routine clinic visits. In this study, only available data from routine care will be collected. No visits or tests are required as part of this study.
