Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to obtain prospective baseline documentation of annualized bleeding rates (ABRs) and treatment under standard-of-care (SOC) therapy among participants with hemophilia A or B. Participants in the study may be eligible to enroll in future planned interventional studies to be conducted by Sponsor.

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.
