Hppnp Tuesday July 6, 2010 The Morning Notes A New Chapter Set to Begin for Celgene “Abraxis Acquisition is an Exceptional Strategic Fit” Expanded pipeline, targeted therapeutics and solid-tumor therapies, create expansive opportunities A major milestone was realized last week when Bob Hugin, Celgene CEO, announced that Celgene had signed an agreement to acquire Abraxis Bio-Science, a California-based biotechnology company headquartered in Los Angeles. For the team members throughout Celgene, news of this major transaction has created a greater level of enthusiasm, evident by the reactions in Celgene offices worldwide. Along with this, and following the closing of the acquisition and integration of Abraxis technologies and products, we will be afforded new opportunities to help even more patients through an expanded portfolio of treatment options. Of particular note will be our ability to immediately address—for the first time—the solid-tumor segment of the oncology market. Through leveraging our existing capabilities and expertise in hematology and oncology we can help advance commercialization efforts to provide patients these much needed therapies. Through this acquisition, we are advancing our global strategy and making important strides toward critical work in the field of oncology, becoming a world leader in the discovery and development of novel approaches to rare and debilitating diseases. About Abraxis... Values, Mission, Complement and Support Celgene Strategic Plan Sharing a similar philosophy and commitment of improving the lives of patients around the world helps make the Abraxis BioScience acquisition an ideal fit. Through this new synergy—and in alignment with our goals and mission—we will be afforded a greater opportunity to alter the course of diseases through the use of cutting-edge, next-generation therapies. By combining resources and technologies, a unified Celgene can further advance its efforts to shift the paradigm of treatment for patients, offering new therapeutic options, targeted on an expanded product portfolio. In addition to its headquarters’ location in Los Angeles, California, Abraxis BioScience also has other locations in the United States, Canada and China. U.S. locations include: Phoenix, Arizona; Chicago, Illinois; Durham, North Carolina, and Bridgewater, New Jersey. Richmond Hill, Ontario, is the location of the Canadian office. And, the Switzerland location is in Barbengo; and, Beijing is home to the location in China. The Abraxis product pipeline includes more than five clinical oncology product candidates in various stages of testing and development. At the center of its solid-tumor focus is ‘Abraxane®,’ a therapeutic compound launched in 2005, and based on its proprietary tumor targeted technology, “nab technology platform.” Abraxane currently is marketed in the United States for the treatment of metastatic breast cancer.
