SILVER SPRING, Md. — The Food and Drug Administration has approved a drug made by Shire for a rare autoimmune condition, the agency said.
The FDA announced the approval of Firazyr (icatibant) for acute attacks of hereditary angioedema in patients ages 18 years and older. HAE, which affects fewer than 30,000 people in the United States, results from improper function of C1 inhibitor, a protein that regulates how certain immune system and blood clotting pathways function.
