Barr Pharmaceuticals, Inc. Announces Warner Chilcott Waives Exclusive License For OVCON(R) 35

WOODCLIFF LAKE, N.J., Sept. 26 /PRNewswire-FirstCall/ -- Barr Pharmaceuticals, Inc. today announced that Warner Chilcott Limited , formerly Galen Holdings PLC, has unilaterally waived the exclusivity provision of the license for Barr’s generic version of Warner Chilcott’s OVCON(R) 35 Tablets oral contraceptive. The waiver makes the license non-exclusive and, as a result, Barr Laboratories, Inc., a subsidiary of Barr Pharmaceuticals, Inc., intends to launch its generic version of OVCON 35 oral contraceptive in October 2006. The Company expects to launch the first generic version of OVCON 35 oral contraceptive under the tradename Balziva(TM).

“Today’s action by Warner Chilcott paves the way for Barr to launch the first generic version of OVCON 35,” said Bruce L. Downey, Barr’s CEO and Chairman. “Following the launch of our Balziva product in October, we will manufacture and market a generic oral contraceptive portfolio that is the largest in the industry, totaling 24 products.”

In March 2004, the Company granted Warner Chilcott an option to acquire an exclusive license under Barr’s Abbreviated New Drug Application (ANDA) for OVCON 35 oral contraceptive. In April 2004, Barr received approval from U.S. Food and Drug Administration (FDA) to manufacture and market a generic version of OVCON 35 oral contraceptive. In May 2004, Warner Chilcott exercised its option to acquire an exclusive license for Barr’s generic version of OVCON 35 oral contraceptive option and was granted a five-year exclusive license to sell the product under Barr’s ANDA. Under a related supply agreement, Barr had been manufacturing OVCON 35 for Warner Chilcott, but does not anticipate further product orders from Warner Chilcott at this time.

OVCON 35 is a regimen of oral contraceptives that contains 0.4 mg of norethindrone and 0.035 mg of ethinyl estradiol and is indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception. The product is supplied in 21-day and 28-day regimens.

OVCON 35 had annual sales of approximately $95 million for the twelve months ending July 2006, based on industry sources.

Barr Pharmaceuticals, Inc. is a holding company whose principal subsidiaries, Barr Laboratories, Inc. and Duramed Pharmaceuticals, Inc., develop, manufacture and market generic and proprietary pharmaceuticals.
