March 28 (Reuters) - Biogen Idec Inc has won U.S. approval for its long-acting hemophilia B treatment Alprolix, the U.S. Food and Drug Administration said on Friday.

Hemophilia B is a rare, inherited disorder in which a person's blood does not clot properly, potentially leading to prolonged bleeding and bruising. It affects about 4,000 people in the United States and 25,000 worldwide.

Alprolix is a bioengineered version of the blood coagulation factor IX, a protein needed for normal blood clotting. Biogen is developing the drug in partnership with Swedish Orphan Biovitrum AB. It received approval in Canada a week ago.
