Santarus Announces Submission of New Drug Application by Schering-Plough for ZEGERID Branded OTC Product

Santarus Entitled to Receive Payments Totaling $22.5 Million Upon Achieving Certain Regulatory Milestones

SAN DIEGO--(HSMN NewsFeed)--Santarus, Inc. (NASDAQ:SNTS ), a specialty pharmaceutical company, today announced that Schering-Plough HealthCare Products, Inc. has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for a ZEGERID® branded omeprazole/sodium bicarbonate product in a 20 mg dosage strength of omeprazole. Schering-Plough is seeking FDA approval to sell the product in the U.S. over-the-counter (OTC) heartburn market, which is estimated at $1.6 billion in 2007 based on data from A.C. Nielsen, a market research firm, and company estimates.

The NDA was submitted under the terms of a license agreement signed in October 2006 for OTC proton pump inhibitor (PPI) products using Santarus’ proprietary technology. Under that agreement, Santarus is entitled to receive up to an additional $22.5 million in regulatory milestones and up to an additional $37.5 million in sales milestones. Santarus previously received from Schering-Plough a $15 million upfront license fee in 2006 and a $5 million milestone payment in 2007 relating to progress on clinical product development strategy. Santarus will also be entitled to a low double-digit royalty, subject to adjustment in certain circumstances, on net sales of any OTC products sold by Schering-Plough under the license agreement. In turn, Santarus will be obligated to pay royalties to the University of Missouri on net sales of any such OTC products.

Under the agreement, Schering-Plough is responsible for the development, manufacturing and commercialization of ZEGERID branded OTC products with the lower dosage strength of 20 mg of omeprazole for heartburn-related indications in the U.S. and Canada. Santarus is continuing to manufacture, promote and sell its ZEGERID (omeprazole/sodium bicarbonate) prescription products in both 20 mg and 40 mg dosage strengths of omeprazole in the U.S. prescription market for PPI products.

Product Description

ZEGERID (omeprazole/sodium bicarbonate) contains omeprazole, a PPI, and sodium bicarbonate, which raises the gastric pH and thus protects omeprazole from acid degradation.

Important Safety Information About ZEGERID Branded OTC Products

The most frequently reported adverse events with ZEGERID are headache, diarrhea, and abdominal pain. Symptomatic response to therapy does not preclude the presence of gastric malignancy. Atrophic gastritis has been noted occasionally in gastric corpus biopsies from patients treated long term with omeprazole.

ZEGERID contains sodium bicarbonate. This should be taken into consideration for patients on a sodium-restricted diet.

ZEGERID is contraindicated in patients with known hypersensitivity to any component of the formulation.
