Duramed's Lo Seasonique NDA Accepted for Filing by FDA

MONTVALE, N.J., February 25, 2008 /PRNewswire-FirstCall/ -- Barr Pharmaceuticals, Inc. today announced that its subsidiary, Duramed Pharmaceuticals, Inc., has received notification that the U.S. Food and Drug Administration (FDA) has accepted for review its New Drug Application (NDA) for Lo Seasonique (levonorgestrel/ethinyl estradiol tablets 0.10 mg/0.02 mg and ethinyl estradiol tablets 0.01 mg) extended-cycle oral contraceptive. The Company is seeking approval to manufacture and market the Lo Seasonique, the first lower dose, extended-cycle oral contraceptive for the prevention of pregnancy. The Prescription Drug User Fee Action (PDUFA) date for the Lo Seasonique NDA is October 24, 2008.

The clinical data supporting the Lo Seasonique NDA resulted from one large pivotal multi-centered, open label clinical trial which concluded in June 2007. The clinical trial involved over 2,200 female subjects between the ages of 18 and 40 at 56 sites throughout the United States. Subjects were enrolled in the clinical trial for a duration of 12 months.

Under the Lo Seasonique extended-cycle regimen, women take active tablets of 0.10 mg levonorgestrel/0.02 mg of ethinyl estradiol for 84 consecutive days, followed by seven days of 0.01 mg of ethinyl estradiol. The regimen is designed to reduce the number of withdrawal bleeding periods from 13 to four per year. By contrast, the majority of oral contraceptive products currently available in the United States are based on a regimen of 21 treatment days, followed by seven days of placebo.

Important Information About Oral Contraceptives

It is estimated that more than 16 million women currently take oral contraceptives in the United States. Oral contraceptives are not for every woman. Serious as well as minor side effects have been reported with the use of hormonal contraceptives. Serious risks include blood clots, stroke, and heart attack. Cigarette smoking increases the risk of serious cardiovascular side effects, especially in women over 35 years. Oral contraceptives do not protect against HIV infection (AIDS) and other sexually transmitted diseases.
