Study to Provide Continued Access to Treatment for Patients Completing a Previous Trial With Efanesoctocog Alfa

Sponsor: Swedish Orphan Biovitrum

Summary

This is a multinational, prospective, open-label, roll-over study in patients with severe haemophilia A, ≥6 years of age, who have completed participation in any of the parental studies with efanesoctocog alfa; XTEND-ed study (LTS16294), FREEDOM study (Sobi.BIVV001-001), or PK comparison study (Sobi.BIVV001-003). The aim of the study is to provide patients with continuous benefit from efanesoctocog alfa treatment and to further continue clinical monitoring for safety and efficacy until efanesoctocog alfa is commercially available in each patient's respective country (or until March 2027, whichever comes first). The study starts with the Baseline Visit, which will be done in connection to the End of Study visit (or equivalent) in the respective parent study. Subsequent study visits (on site or phone call) will be done approximately every 13 weeks until End of Treatment. An End of Study safety phone call will be done 14 (+7) days after the End of Treatment Visit.
