Summary
Brief summary
The aim of this prospective, observational study is to establish a dataset on the frequency
of bleeding events, as well as other characteristics of bleeding events and FVIII infusions,
in patients with clinically severe hemophilia A receiving prophylactic FVIII replacement
therapy as standard of care. The data collected from this study may assist in providing
baseline information for comparison to the Spark's investigational hemophilia A gene therapy
in future Phase 3 studies.
