This study looks at a new medicine called **Mim8** for people with *haemophilia A*, a condition where blood doesn't clot properly. Some people with haemophilia A have inhibitors, which are substances that stop clotting treatments from working, while others do not. Mim8 helps by acting like the missing *clotting factor VIII (FVIII)* in the blood to prevent bleeding. This study can last up to 5.5 years, or until 2028, whichever comes first. Participants will receive injections under the skin weekly, bi-weekly, or monthly, up to a maximum of 262 injections, depending on the treatment schedule. Participants must follow certain rules about what other medicines they can use during the study. Women cannot join if they are pregnant, breastfeeding, or planning to get pregnant.

• The study requires participation in previous related studies.
• It involves regular injections and diary entries.
• Women must use effective birth control if of child-bearing age.
