As previously announced, the companies estimate that full year 1999 sales of the combined continuing operations of Pharmacia & Upjohn and Monsanto will consist of approximately $11.3 billion in pharmaceutical sales and $5.2 billion in sales from the agricultural business. Between 1999-2002, the pharmaceutical business of the combined company is expected to grow at annual compounded rate of 14-15%, including a 16-18% increase in prescription pharmaceutical sales. After 2000, the combined company is expected to achieve annual earnings per share growth of more than 20%. Between 1999-2002, new and blockbuster products are expected to account for an incremental $5.5 billion in pharmaceutical sales led by Celebrex, a new arthritis treatment which generated 1999 sales of more than $1.5 billion in its first year on the market. Other products expected to contribute to the immediate growth of the new company include Xalatan, a treatment for glaucoma, which had 1999 sales of more than $500 million; Detrol, for overactive bladder, which had sales of more than $300 million in 1999; and Camptosar, for colorectal cancer, which recorded sales of more than $290 million in 1999. In relation to its key pharmaceutical products, the companies announced that the U.S. Food and Drug Administration has granted priority review to a New Drug Application (NDA) submitted in late 1999 for a fixed combination of Xalatan and timolol for the treatment of glaucoma. This represents the third priority review granted to the companies in recent months by FDA. Pharmacia & Upjohn's new antibiotic Zyvox is currently under priority along with a filing for Camptosar in the first line treatment of metastatic colorectal cancer. -more- Later this month, Pharmacia & Upjohn plans to submit applications to U.S. and European regulatory authorities for a once-daily formulation of Detrol. In a recently completed major clinical study, Once Daily (OD) Detrol demonstrated a superior efficacy and safety profile vs. placebo on all key measurements. The incidence of dry mouth among patients taking the OD product was 23%, significantly better than competitive products and an improvement over the currently marketed Detrol formulation. The OD product is expected to strengthen Detrol's leadership of the overactive bladder market In the U.S., an NDA has also been submitted for Axert (almotriptan), a new treatment for acute migraine. The companies also announced the completion of enrollment in the Celecoxib Longterm Arthritis Safety Study (CLASS), a study of gastrointestinal side effects in Celebrex versus traditional non-steroidal anti-inflammatory drugs (NSAIDs).
