Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a prospective, non-randomized, controlled study to examine whether or not having a higher trough during prophylactic treatment with clotting factor offers better joint protection than the standard trough of 1% Factor IX (FIX or Factor 9). This study will test the hypothesis that an extended half-life (EHL) FIX product with an intended trough of \>10% could offer better protection than previous treatment concentrates. This study also examines whether or not joint damage could be diagnosed earlier using ultrasound images.
