Watson Pharmaceuticals, Inc. (NYSE: WPI) today announced an exclusive, worldwide licensing agreement with Itero Biopharmaceuticals, Inc., a venture-backed specialty biopharmaceutical company, to develop and commercialize Itero's Recombinant Follicle Stimulating Hormone (rFSH).

"This project will capitalize on the world-class biologics capabilities of our Eden Biodesign group and represents a substantial step in Watson's goal to build a significant position in the global biopharmaceutical marketplace."

"The Eden and Brand research and development teams will manage the development activities, and if we are successful, the Brand commercial organization will add another major product to our portfolio."

"We are excited to partner with an industry leader in women's health to complete the development and commercialization of our first biologic asset. Watson has a strategic focus on growing its women's health business and this product targets the expanding $1.2 billion infertility segment of this market," said V. Bryan Lawlis, Ph.D., President and CEO of Itero Biopharmaceuticals.
