All Eligible Participants - All Participants diagnosed with severe HemA with or without inhibitors, moderately severe to severe HemB, or HemB with inhibitors will be enrolled and continue to receive their usual hemophilia treatment regimen under SOC therapy. Bleeding episodes and treatment data will be collected during the prospective follow up period in a diary. No intervention will be administered as part of this study.
