Dear Mr. Moran:

 

We have reviewed your submission dated April 16, 2013 to your biologics license application (BLA) for C1 Esterase Inhibitor (Recombinant) requesting a proprietary name review. 

In consultation with CBERs Advertising and Promotional Labeling Branch (APLB) we conclude that your proposed proprietary name, RUCONEST, is acceptable at this time under the Federal Food, Drug, and Cosmetic Act and applicable regulations.

We will perform another proprietary name review of RUCONEST closer to the time of the action due date to ensure that we have not approved a conflicting proprietary name for another product in the interim.

If you have any questions, please contact Nannette Cagungun at (301) 827-6174.

Sincerely yours,

/s/
