In a letter to FDA dated October 10, 2000, Serono, Inc., voluntarily requested the withdrawal of NDA 17-873 for Breokinase® (Urokinase for Injection). Serono, Inc., neither intends to market the product in the United States nor export it from the United States. The firm voluntarily requested that FDA withdraw NDA 17-873, and therefore has waived its opportunity for a hearing. In a December 13, 2000, letter to the firm, FDA acknowledged receipt of the request and stated it would proceed (to publish a Federal Register notice) withdrawing the NDA.

Therefore, under section 505(e) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(e)) and under authority delegated to the Director, Center for Biologics Evaluation and Research (21 CFR 5.82), approval of the application listed in this document, and all amendments and supplements thereto, is hereby withdrawn, as of July 23, 2001.
