(NASDAQ: DRMD) AND SOLVAY PHARMACEUTICALS, Inc. today announced they have entered into a 10-year marketing agreement whereby the two companies will share in the marketing and profits of Duramed's Cenestin (registered trademark) (synthetic conjugated estrogens, A) Tablets. "This alliance deepens the existing co-promotion agreement between Duramed and Solvay Pharmaceuticals," said Duramed Chairman and Chief Executive Officer E. Thomas Arington. "This is a highly significant beneficial alliance and gives Duramed renewed strength and a fresh start as we work with Solvay Pharmaceuticals to make Cenestin (registered trademark) top of mind among physicians and consumers." "Since the alliance between Solvay Pharmaceuticals and Duramed Pharmaceuticals began, total prescriptions for Cenestin (registered trademark) from OB/GNYs have increased almost five- fold," said David A. Dodd, Solvay Pharmaceuticals President and Chief Executive Officer. "The expansion of our co-promotion alliance is a reaffirmation of our shared commitment to offer women a variety of sale and effective hormone replacement therapy treatments." Effective January 1, 2000, Solvay Pharmaceuticals, the second largest pharmaceutical company in the U.S. hormone replacement therapy market, assumed responsibilities for the marketing of Cenestin (registered trademark). This responsibility also includes assuming all advertising and sales promotion expenses for Cenestin (registered trademark), including all expenses associated with Duramed's sales force. During this initial stage of the marketing agreement, Solvay Pharmaceuticals will receive 80 percent of the gross profit from Cenestin (registered trademark) and Duramed will receive 20 percent of Cenestin (registered trademark)'s gross profit until Solvay Pharmaceuticals has recovered all of the ongoing advertising and marketing expenses and Cenestin (registered trademark) becomes an income-producing product. The agreement then moves into a second stage, where Duramed will receive 80 percent of Cenestin (registered trademark)r net profit dollars and Solvay Pharmaceuticals will receive 20 percent, until Duramed recovers the $38 million it invested in Cenestin (registered trademark) since the product was approved in March 1999. Upon completion of these two stages, when both Duramed and Solvay Pharmaceuticals have recovered the specified investments, the two companies each will receive 50 percent of Cenestin (registered trademark) net profit dollars on a moving-forward basis. Duramed also granted Solvay Pharmaceuticals a worldwide exclusive license to Cenestin (registered trademark) outside the United States. The global rights to Cenestin (registered trademark) include all countries except Puerto Rico and Eastern Europe countries that are currently covered by other established marketing partners. Solvay Pharmaceuticals and Duramed will enter into mutually agreed upon license and supply agreements for each country as opportunities arise. Solvay Pharmaceuticals has also been granted the option to an exclusive worldwide license to Verapamil SR, a calcium channel blocker for the treatment of hypertension, which has been previously approved by the FDA. This agreement deepens an alliance Solvay Pharmaceuticals and Duramed established in October 1999 when the two companies jointly promote Duramed's Cenestin (registered trademark) (synthetic conjugated estrogens, A) Tablets and Solvay Pharmaceuticals' Estratest (registered trademark)/Estrates (registered trademark) H.S. Tablets (esterified estrogens and methyltestosterone) and Prometrium (registered trademark) (progesterone) Capsules*. Starting October 11, 1999, an expanded national sales force of approximately 300 Duramed and Solvay Pharmaceuticals sales representatives began calling on obstetricians and gynecologists across the United States, providing product information, samples and patient education materials.
