The Ministry of Health in Kuwait has approved efmoroctocog alfa (Elocta®), a recombinant human factor VIII Fc-fusion protein, for the treatment of hemophilia A.
It is indicated for both on-demand and prophylactic treatment in hemophilia A patients of all ages.
Efmoroctocog alfa is the first recombinant factor VIII Fc fusion protein therapy approved for the treatment of hemophilia A in the Middle East region.
Efmoroctocog alfa is also approved in the European Union, Switzerland, Iceland, Liechtenstein, Norway, the US, Canada, Australia, New Zealand, Brazil, Taiwan, and Japan.
Efmoroctocog alfa was developed by fusing B-domain deleted factor VIII to the Fc portion of immunoglobulin G subclass 1. It is believed that this enables efmoroctocog alfa to utilize a naturally occurring pathway to prolong the time the therapy remains in the body.
Sobi and Biogen are collaborators in the development and commercialization of efmoroctocog alfa for hemophilia A.
The approval of efmoroctocog alfa in Kuwait was based on data from a pair of phase 3 studies: A-LONG and Kids A-LONG.
A-LONG
The A-LONG study included 165 previously treated males 12 years of age and older with severe hemophilia A. Researchers evaluated individualized and weekly prophylaxis to reduce or prevent bleeding episodes and on-demand dosing to treat bleeding episodes.
Prophylaxis with efmoroctocog alfa resulted in low annualized bleeding rates, and a majority of bleeding episodes were controlled with a single injection of efmoroctocog alfa.
None of the patients developed neutralizing antibodies, efmoroctocog alfa was considered well-tolerated, and the product had a prolonged half-life when compared with recombinant factor VIII.
Kids A-LONG
The Kids A-LONG study included 71 boys (younger than 12) with severe hemophilia A who had at least 50 prior exposure days to factor VIII therapies.
The children saw their median annualized bleeding rate decrease with efmoroctocog alfa, and close to half of the children did not have any bleeding episodes while they were receiving efmoroctocog alfa.
None of the patients developed inhibitors, and researchers said adverse events were typical of a pediatric hemophilia population.
