Santarus Announces FDA Acceptance of New Drug Application for Zegerid Tablet Product

SAN DIEGO--(BUSINESS WIRE)--Apr 6, 2009 - Santarus, Inc. (NASDAQ:SNTS), a specialty pharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing the company's New Drug Application (NDA) for a new tablet formulation to add to its ZEGERID® family of branded prescription pharmaceutical products. Pursuant to Prescription Drug User Fee Act (PDUFA) guidelines, Santarus expects the FDA will complete its review or otherwise respond to the NDA by December 4, 2009.

The NDA was submitted under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act. In connection with the FDA's acceptance for filing of the NDA for a new tablet formulation, Santarus is providing notice to the NDA holder for Prilosec® (omeprazole) delayed-release capsules and related patent holders that the new tablet formulation does not infringe the patents listed in the Orange Book for Prilosec or that those patents are invalid.

About Currently Marketed ZEGERID Prescription Products

ZEGERID (omeprazole/sodium bicarbonate) Capsules and Powder for Oral Suspension are indicated for the treatment of heartburn and other symptoms associated with gastroesophageal reflux disease (GERD), maintenance of healing and short-term treatment of erosive esophagitis, and short-term treatment of active benign gastric ulcers and active duodenal ulcers. ZEGERID Powder for Oral Suspension 40 mg is also indicated for the reduction of risk of upper gastrointestinal bleeding in critically ill patients.

ZEGERID Capsules and Powder for Oral Suspension contain a combination of omeprazole, a proton pump inhibitor (PPI), and sodium bicarbonate, an antacid, which raises the gastric pH and thus protects the omeprazole from acid degradation.

ZEGERID products offer a distinct pharmacological profile – rapidly reaching maximal plasma levels (in approximately 30 minutes) and providing strong acid control. While the correlation of pharmacodynamic data to clinical effect has not been established, the median percentage of time gastric pH was greater than 4 over 24 hours in patients treated with ZEGERID in a pharmacodynamic study ranged from 12.2 hours to 18.6 hours, depending on the strength and dosage form, after repeated once-daily dosing. ZEGERID can be conveniently taken once-a-day on an empty stomach, at least one hour before a meal.

PPIs are widely prescribed for a variety of diseases and disorders of the upper digestive tract. All currently marketed oral PPIs in the U.S., other than ZEGERID, are delayed-release formulations that utilize an enteric coating to protect the PPI from acid degradation, thereby delaying absorption and initial acid suppression. Unlike delayed-release PPIs, ZEGERID Capsules and Powder for Oral Suspension utilize an antacid in lieu of an enteric coating. The antacid neutralizes stomach acid and protects the PPI, omeprazole, from gastric acid degradation and allows for its rapid absorption and suppression of gastric acid.

Important Safety Information About ZEGERID Capsules and Powder for Oral Suspension

The most frequently reported adverse events with ZEGERID are headache, diarrhea, and abdominal pain. In 178 critically ill patients treated with ZEGERID Powder for Oral Suspension, adverse events generally reflected the serious, underlying medical condition of the patients, but some adverse events occurred with more frequency in patients treated with ZEGERID Powder for Oral Suspension than in those treated with the comparator (acid-controlling) drug. For more information about these and other events, please see Table 13 of the full Prescribing Information at 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 Capsules contain 304 mg of sodium per dose. ZEGERID Powder for Oral Suspension contains 460 mg of sodium per dose. This should be taken into consideration for patients on a sodium-restricted diet.

Sodium bicarbonate is contraindicated in patients with metabolic alkalosis and hypocalcemia. ZEGERID is contraindicated in patients with known hypersensitivity to any component of the formulation.

Since both 20 mg and 40 mg ZEGERID contain the same amount of sodium bicarbonate (1100 mg in capsules, 1680 mg in packets of powder for oral suspension), two 20 mg capsules are not equivalent to, and should not be substituted for, one 40 mg capsule, and two 20 mg packets are not equivalent to, and should not be substituted for, one 40 mg packet.
