Item 8.01 Other Events.

Emergent BioSolutions Inc. today announced that the U.S. Food and Drug Administration has issued a complete response letter for the New Drug Application of IXINITY™ [coagulation factor IX (recombinant)] for the control and prevention of bleeding episodes and perioperative management in adults and children, 12 years old and above, living with Hemophilia B.

The complete response letter requested additional analyses of data from completed studies and noted deficiencies in the CMC section of the license application, all of which must be resolved before approval can be granted by FDA. The company plans to engage with the FDA to better ascertain the requirements for approval, following which it will determine its next steps. The company does not anticipate launching the product in 2014.
