The European Medicines Agency (EMA) has accepted and verified Sobi’s marketing authorisation application for a new factor VIII (FVIII), efanesoctocog alfa, to treat haemophilia A patients of all ages.

The application is supported by results from the Phase III XTEND-1 trial in adults and adolescents and backed by the XTEND-Kids paediatric trial in patients aged under 12 years.

In February 2023, the US Food and Drug Administration approved efanesoctocog alfa as ALTUVIIIO.

Efanesoctocog alfa is a new and investigational recombinant FVIII therapy with the potential to provide near-normal factor activity levels for significant portions of the week, thereby enhancing bleed protection through a once-a-week dose for haemophilia A patients.

Haemophilia A is a rare genetic disorder in which blood-clotting ability is impaired because of the absence of FVIII.

It affects around one in 5,000 males at birth per year but is rare in females.
