Item 8.01 Other Events.

In August 2012, Santarus, Inc. ("Santarus"or the "Company") announced that the U.S. Food and Drug Administration (the "FDA") had extended the Prescription Drug User Fee Act ("PDUFA") target action date for the review of the New Drug Application ("NDA") for Uceris™ (budesonide) tablets 9 mg for the induction of remission of mild to moderate active ulcerative colitis from October 16, 2012 to January 16, 2013. In connection with the extension of the PDUFA date, the FDA also notified Santarus that the FDA planned to communicate proposed labeling to Santarus by December 12, 2012.

On December 12, 2012, the FDA informed Santarus that it plans to provide proposed labeling to Santarus later in the month of December.

Santarus cannot be certain that the FDA will provide the proposed labeling in a timely manner or at all or that the FDA will approve the Uceris NDA in a timely manner or at all, even if the initial proposed labeling is received. If FDA approval is received on or before the PDUFA date, Santarus anticipates that it will be in a position to commence the commercial launch of Uceris in the first quarter of 2013.
