Depomed Files Prior Approval Supplement for 1000 mg Strength Tablets of Glumetza

Business Wire, April 2, 2007

MENLO PARK, Calif. -- Depomed, Inc. (NASDAQ:DEPO) announced today that it has filed a prior approval supplement with the U.S. Food and Drug Administration (FDA) seeking approval to market in the United States 1000 mg strength tablets of Glumetza(TM)(metformin hydrochloride extended release tablets). The company expects the FDA to make a determination on the filing before the end of the third quarter of this year.

"This filing takes us one step closer to making the management of type 2 diabetes more convenient for adults who prefer to take fewer tablets each day," stated Carl Pelzel, executive vice president and chief operating officer of Depomed. "We hope to obtain marketing approval for the 1000 mg tablets later this year and to make them commercially available in the United States soon thereafter."

The new formulation, which Biovail was in the process of formulating when Depomed acquired rights to the product in December 2005, would replace the 1000 mg strength tablet currently covered by the Glumetza New Drug Application. The supplement filed with the FDA includes data from a comparative bioavailability study demonstrating that the 1000 mg strength tablets achieved equivalent peak and systemic exposure when compared to Glumetza 500 mg tablets given as two tablets under single-dose fed conditions. No serious adverse events were reported.

About Diabetes

Diabetes affects an estimated 20 million Americans and its incidence is increasing by approximately 1 million new cases each year in the United States alone. Approximately 90 percent to 95 percent of people with diabetes suffer from type 2 diabetes, the most common metabolic disease in the world and the fifth deadliest disease in the United States. Diabetes is the leading cause of blindness, end-stage renal disease, and non-traumatic loss of limb. It can also lead to heart disease, stroke, high blood pressure, kidney disease, and other serious conditions. In the United States, the public health cost of diabetes is more than $130 billion per year. In August 2006, the American Diabetes Association and the European Association for the Study of Diabetes issued a consensus statement recommending that treatment with metformin be initiated at diagnosis along with lifestyle changes in patients with type 2 diabetes.

About Glumetza

Glumetza[TM] (metformin hydrochloride extended release tablets) is indicated alone or in combination with sulfonylurea or insulin as an adjunct to diet and exercise to improve glycemic control in adult patients (18 years and older) with type 2 diabetes. Glumetza may be used concomitantly with a sulfonylurea or insulin to improve glycemic control in adults.

Glumetza is contraindicated in patients with renal disease or renal dysfunction (e.g., as suggested by serum creatinine levels greater than or equal to 1.5 mg/dL in males and greater than or equal to 1.4 mg/dL in females), known hypersensitivity to metformin HCl, and acute or chronic metabolic acidosis, including diabetic ketoacidosis with or without coma. As with all metformins, there is a boxed warning regarding lactic acidosis with Glumetza due to metformin accumulation during treatment. Lactic acidosis is a rare but potentially fatal occurrence. It may also occur in association with a number of pathophysiologic conditions. The risk of lactic acidosis increases with the degree of renal dysfunction and the patient's age, especially patients 80 years of age or older. In clinical trials of Glumetza combined with a sulfonylurea, the most common side effects included hypoglycemia, diarrhea, and nausea.
