"Acquiring the rights to Itero's rFSH product represents our first in-licensing of a biosimilar development project, and demonstrates the execution of our plan to build a pipeline of biosimilar products, through both internal development and external partnering with high quality biopharmaceutical companies such as Itero," said Paul Bisaro, Watson's President and CEO.  "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."

"Our agreement with Itero also represents continued delivery on our commitment to expand our brand product pipeline with distinctive product opportunities in the growing women's health market," said Watson's Fred Wilkinson, Watson's Executive Vice President, Global Brands.  "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. "Itero has created significant value in our rFSH program in just two years, and this collaboration validates our business strategy and capabilities for the cost efficient development of protein therapeutics.  Moreover, it gives Itero the resources to further pursue the development of additional biopharmaceutical products and partnering activities."
