Long-term Safety and Effectiveness Study of Mim8 Injection Treatment for People With Haemophilia A With or Without Inhibitors

What this Trial Is About

Researchers are evaluating Mim8, a new medicine designed to help people with haemophilia A, including those with or without inhibitors. Mim8 aims to prevent bleeding episodes by replacing the function of the missing clotting factor VIII. This long-term study will last up to 5.5 years, ending either when Mim8 is approved in the participants country or by June 2028, whichever comes first. The study includes participants who have been involved in earlier related studies or are new infants with severe haemophilia A. Participants will receive Mim8 as a preventive treatment through subcutaneous injections. Depending on their entry point, participants may use an enhanced cartridge or a DV3407 pen-injector device for administering Mim8. The treatment is given regularly over the study period, with participants potentially receiving up to 262 injections. In the event of bleeding, additional haemostatic medications may be used as agreed with the study doctor. Female participants who are pregnant, breastfeeding, or planning pregnancy during the study are not eligible. During the study, participants will be monitored for any side effects, including injection site reactions and the development of antibodies against Mim8. Researchers will also track bleeding episodes, Mim8 blood levels, and device handling for some participants. Participants and their representatives will complete diaries and questionnaires about their treatment and health. Safety will be carefully followed throughout the study, which may last several years depending on individual enrollment and study progress.
