Depomed’s ProQuin(R) XR Achieves First Marketing Authorization in Europe

July 23, 2008

Depomed, Inc. (NASDAQ:DEPO) and Rottapharm/Madaus announced today that the Marketing Authorization (MA) for ProQuin XR has been received from the Medical Products Agency in Sweden. Depomed’s ProQuin XR is exclusively licensed to Rottapharm/Madaus for Europe and is a once-daily extended-release formulation of ciprofloxacin hydrochloride for the treatment of uncomplicated urinary tract infections.

“We are glad to see ProQuin XR be approved in Sweden as reference member state which is a first step to make it commercially available in Europe. We feel confident that our partner Rottapharm/Madaus with their strong market presence and local expertise in individual European countries will realize ProQuin XR’s commercial potential in Europe. We anticipate the commercial rollout and pricing in other European countries will progress through next year,” noted Carl A. Pelzel, president and chief executive officer of Depomed.

Antonino Santoro, corporate business development and regulatory affairs director of Rottapharm/Madaus, added, “ProQuin XR complements our product portfolio and strengthens our position in urology. ProQuin XR’s approval in Sweden paves the way for further regulatory approvals in other European countries through the mutual recognition procedure; we expect to launch the product under the trade-mark UTIMINX(TM) starting in 2009 in different countries and in some of them we are planning to co-market the product under the secondary trade-mark URITENT(TM).”

About ProQuin(R) XR

ProQuin XR is a once-daily extended-release formulation of ciprofloxacin hydrochloride and is intended to treat uncomplicated urinary tract infections (UTIs). UTIs are bacterial infections frequently caused by E. coli and are typically treated with antibiotics. Patients should not take ProQuin XR if they are allergic to, or have ever had a severe reaction to, ciprofloxacin or to any other “quinolone” antibiotics. Proquin XR is generally well tolerated. The most common side effects with Proquin XR include vaginal yeast infection and headache. UTIs are the second-most common type of bacterial infection, after those of the respiratory tract, with more than 35 million medically treated infections across the seven major markets each year. This translated into sales in excess of $1.1billion across key markets.

Formulated with AcuForm(TM) delivery technology, Proquin XR is delivered over a six-hour period to the upper gastrointestinal (GI) tract where ciprofloxacin is best absorbed. This controlled, targeted delivery allows for nearly 87 percent of the active ingredient to enter into the blood stream and less unabsorbed drug to pass through to the lower GI tract where it can cause irritation and give rise to side effects. Proquin XR is the first version of ciprofloxacin with nausea and diarrhea listed as “uncommon” adverse events in its label, rather than “common” adverse events.
