What this Trial Is About

This is a national, multicenter, retrospective/prospective, observational study in Taiwan designed to assess effectiveness, safety, and usage of efanesoctocog alfa prophylaxis treatment in hemophilia A participants. The data related to efanesoctocog alfa effectiveness, safety and usage will be recorded prospectively during routine visits for up to 5 years following enrollment initiation and the retrospective data will be collected at least 12 months and up to 24 months prior to efanesoctocog alfa initiation. Joint imaging data will be collected in centers performing Joint U/S and/or MRI (≥6 years old). At least 12 months of retrospective data will also be collected from medical records, as available. Prospectively collected data will be recorded at routine clinical visits during a five-year follow-up period. The end of study is defined as the last participant's last visit. No intervention will be administered, and no study related visits are required.
