Amgen Licenses Molecule for the Treatment of Chronic and Neuropathic Pain to Ortho-McNeil-Janssen Pharmaceuticals, Inc.

THOUSAND OAKS, Calif.--(BUSINESS WIRE)--July 31, 2008--Amgen (NASDAQ: AMGN) today announced that it has licensed a clinical stage molecule for the treatment of chronic and neuropathic pain to Ortho-McNeil-Janssen Pharmaceuticals, Inc. (OMJPI), a Johnson & Johnson company. The terms of the agreement include a $50 million upfront payment, the potential for $385 million in success-based milestones and additional sales based milestones and royalties on sales.

The agreement provides OMJPI with global rights to the product, but excludes Japan where Amgen has entered into a previous license agreement with respect to the compound. OMJPI and its affiliates will be responsible for future development and commercialization of the compound, a fully human anti-nerve growth factor (NGF) antibody.

"OMJPI's proven capabilities in developing and marketing pain therapeutics make them an ideal partner to bring this potentially important molecule to patients who suffer chronic pain," said Roger M. Perlmutter, M.D., Ph.D., Amgen's executive vice president of Research and Development.

The agreement is subject to clearance under the Hart-Scott-Rodino Antitrust Improvements Act.

Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. The Company's results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments (domestic or foreign) involving current and future products, sales growth of recently launched products, competition from other products (domestic or foreign) and difficulties or delays in manufacturing our products. In addition, sales of our products are affected by reimbursement policies imposed by third-party payors, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and health care cost containment as well as U.S. legislation affecting pharmaceutical pricing and reimbursement. Government and others' regulations and reimbursement policies may affect the development, usage and pricing of our products. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or manufacturing problems with our products after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors. We depend on third parties for a significant portion of our manufacturing capacity for the supply of certain of our current and future products and limits on supply may constrain sales of certain of our current products and product candidate development. In addition, we compete with other companies with respect to some of our marketed products as well as for the discovery and development of new products. Discovery or identification of new product candidates cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers.
