AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- You have been diagnosed with moderate or severe hemophilia A, meaning your body makes very little or none of a clotting protein called Factor VIII (5% or less than normal)
- You either have never developed inhibitors (antibodies that block treatment) or have not had detectable inhibitors for at least three years
- You have recently started treatment with a medication called efanesoctocog alfa as part of your regular care, no more than three months before joining the study
- You are 6 years old or older and are able to have an MRI scan (sedation can be provided if needed, based on the doctor's judgment)
- You are able to have your joints examined as part of the study
- Your doctor decided to prescribe efanesoctocog alfa for you before and separately from this study — not because of the study
- You (or your parent/legal guardian if you are under the legal age of consent) have signed and agreed to participate, and children will also be asked for their own agreement where local rules require it
Who may not be able to join:
- You have a blood clotting disorder other than hemophilia A
- You have been diagnosed with any other known bleeding disorder
- You are currently receiving Factor VIII therapy but it does not seem to be working as well as expected
- Your ankle joints already show significant damage based on X-ray scoring above a certain level (confirm with trial site)
