An Observational Study to Learn More About How Well Damoctocog Alfa Pegol Works in Previously Treated Children With Hemophilia A

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is an observational study of children with mild, moderate, or severe hemophilia A who are receiving damoctocog alfa pegol, and are between 7 to \<12 years of age at the time of enrolment. Observational studies use data that are collected as part of routine medical care and participants do not receive any advice or any changes to healthcare as part of the study. In this study, the data will be collected from participants who are receiving their usual treatment with damoctocog alfa pegol as prescribed by their doctor. These children have previously received damoctocog alfa pegol or other factor 8 (FVIII) products. 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. At times, there is spontaneous bleeding into the joint spaces that leads to joint damage. The drug observed in this study, damoctocog alfa pegol, is approved for doctors to prescribe to children who are at least 7 years old with hemophilia A. It is used to prevent or treat bleeding episodes and works by replacing missing FVIII in the body of people with hemophilia A. The participants will receive damoctocog alfa pegol as prescribed independently by their own doctors during routine practice, not as a part of the study. Participants may choose to enroll in the study at any time after their doctor has prescribed damoctocog alfa pegol to prevent bleeding episodes. The main purpose of this study is to learn more about how a treatment with damoctocog alfa pegol works to prevent bleeding episodes in routine medical practice. To answer this question, doctors will collect: * information about bleeding episodes including the type and the location of the bleed * information about the treatment with damoctocog alfa pegol and other FVIII products * the overall health status of the participants Data will be collected from participants over two years after they enroll in the study or until they choose to leave the study or switch to another hemophilia A treatment. Historical data will come from the participants' medical records or by interviewing the patient and parent/ legal guardian. The children's parents/ guardians will be asked to maintain a health diary to record details of bleeding episodes and treatment with damoctocog alfa pegol. The children's parents/ guardians will also be asked to answer a questionnaire (Hemo QoL-SF and PedHAL) to assess the effect of hemophilia on their child's daily life. In this study, only available data from routine care will be collected. No additional visits or tests are required as part of this study.
