Amgen (NASDAQ:AMGN) and Micromet, Inc. (NASDAQ:MITI) today announced that the companies have entered into a definitive merger agreement under which Amgen will acquire Micromet, a biotechnology company founded in Germany with its research and development (R&D) center in Munich and headquarters in Rockville, Md., for $11 per share in cash. The transaction, which values Micromet at approximately $1.16 billion, was unanimously approved by both the Amgen and Micromet Boards of Directors.

The acquisition includes blinatumomab, a Bispecific T cell Engager (BiTE) antibody in Phase 2 clinical development for acute lymphoblastic leukemia (ALL). Blinatumomab is also in clinical development for the treatment of non-Hodgkin's lymphoma (NHL), and could have applications in other hematologic malignancies.

"The acquisition of Micromet is an opportunity to acquire an innovative oncology asset with global rights and a validated technology platform with broad potential clinical applications," said Kevin Sharer, chairman and CEO at Amgen. "Blinatumomab will serve as an important complement to our oncology pipeline and is representative of our corporate strategy, which is focused on developing and successfully commercializing therapeutics to treat patients with grievous illness."

Amgen will gain the following as a result of the acquisition:

• Blinatumomab, a BiTE antibody that has demonstrated encouraging single-agent activity in both adult and pediatric patients with ALL as well as adult patients with NHL, and is currently under investigation in five trials:
  • Two Phase 2 trials for adult patients with relapsed/refractory ALL
  • Phase 1/2 trial for pediatric patients with relapsed/refractory ALL
  • Phase 2 trial for adult ALL patients with minimal residual disease (MRD)
  • Phase 1 trial for adult patients with relapsed/refractory NHL
• Proprietary BiTE antibody technology which provides an innovative, validated platform for future clinical research
• Potential milestone and royalty payments from existing licensees of BiTE and other technologies
• Unencumbered rights to solitomab, a BiTE antibody in Phase 1 for patients with advanced solid tumors
• Micromet's Munich site, which will operate as an Amgen R&D center of excellence

"We believe that this transaction represents an attractive opportunity for Micromet, its stockholders and cancer patients," said Christian Itin, Ph.D., Micromet's president and CEO. "Amgen's extensive resources and experience in the development and commercialization of biologics promise to speed blinatumomab's path to market, expand its development across a broader range of B-cell malignancies and maximize the full potential of our novel BiTE technology."

Terms of the Transaction
Under the terms of the merger agreement, a subsidiary of Amgen Inc. will commence a tender offer to acquire all of the outstanding shares of Micromet's common stock at a price of $11 per share in cash. Following the purchase of shares through the tender offer, Amgen will complete the transaction by acquiring all remaining shares not acquired in the offer through a merger at the same price as the tender offer. The consummation of the tender offer is subject to various conditions, including a minimum tender of at least a majority of outstanding Micromet shares on a fully diluted basis, the expiration or termination of the waiting period under the Hart Scott Rodino Antitrust Improvements Act and other customary conditions. The tender offer is not subject to a financing condition. The transaction is expected to close in the first quarter.

Amgen is advised by Moelis & Company LLC and Sullivan & Cromwell LLP. Goldman, Sachs & Co. and Cooley LLP are acting as financial and legal advisors, respectively, to Micromet.
