Independent Data Monitoring Committee Recommends Resuming Enrollment of Non-Squamous NSCLC Patients in the Motesanib MONET1 Trial

THOUSAND OAKS, Calif. and CAMBRIDGE, Mass., Feb. 11 and OSAKA, Japan (Feb. 12, 2009) /PRNewswire-FirstCall/ -- Amgen (Nasdaq: AMGN), Millennium: The Takeda Oncology Company, and its parent company Takeda Pharmaceutical Company Limited (TSE:4052) today announced the Independent Data Monitoring Committee (DMC) for the MONET1 trial has recommended the trial resume enrollment of patients with non-squamous non-small cell lung cancer (NSCLC) following a three-month enrollment suspension. MONET1 is a Phase 3 study evaluating motesanib (AMG 706) in combination with paclitaxel and carboplatin for the first-line treatment of advanced NSCLC. Motesanib is part of a co-development program between Amgen, Millennium and Takeda.

The recent DMC guidance recommends the trial be re-opened only to patients with non-squamous cell histology. Non-squamous cell NSCLC is a histological subtype of NSCLC representing approximately two-thirds of the study population. Amgen, Millennium and Takeda plan to follow this recommendation which will require modifications to the study design of MONET1. Enrollment will resume once these changes are sanctioned by appropriate global health authorities.

In November 2008 the DMC recommended treatment discontinuation in subjects with squamous histology, and enrollment suspension in subjects with non-squamous histology. This recommendation was based on an observation of higher early mortality rates in the motesanib group compared to the placebo group and a higher incidence of hemoptysis in the squamous population. Patients with non-squamous NSCLC receiving motesanib were allowed to continue treatment during the temporary suspension.

"We endorse the DMC's decision to include only patients with non-squamous cell tumors in MONET1," said Roger M. Perlmutter, M.D., Ph.D., executive vice president of Research and Development at Amgen. "This decision gives us confidence we have selected the right patient population to explore the clinical potential of motesanib in non-small cell lung cancer."

"NSCLC continues to be an area where new and effective therapies are needed, and we are optimistic about the potential of motesanib in patients with non-squamous NSCLC," said Nancy Simonian, M.D., chief medical officer, Millennium: The Takeda Oncology Company. "We are pleased with the DMC recommendation and will work with appropriate regulatory agencies and investigators to resume enrollment as soon as possible."

MONET1 (Motesanib NSCLC Efficacy and Tolerability Study) Trial Design

The primary endpoint is overall survival, and secondary endpoints include progression-free survival, objective response rate in patients with measurable disease, duration of response and safety. Patients were randomized 1:1 to receive paclitaxel and carboplatin administered every three weeks with or without 125 mg motesanib taken daily.

About Motesanib

Co-developed by Amgen, Takeda Pharmaceutical Company and Millennium: The Takeda Oncology Company, motesanib is an investigational, highly selective, oral agent that is being evaluated for its ability to inhibit angiogenesis by targeting vascular endothelial growth factor receptors 1, 2 and 3 (VEGFR1-3). It is also under investigation for its potential direct anti-tumor activity by targeting a family of proteins called tyrosine kinases, including platelet-derived growth factor receptor (PDGFR), and stem cell factor receptor (c-kit), two proteins involved in cell proliferation.

Forward-Looking Statements

This news release contains forward-looking statements that are based on Amgen's current expectations and beliefs and are subject to a number of risks, uncertainties and assumptions that could cause actual results to differ materially from those described. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission (SEC) reports filed by Amgen, including Amgen's most recent annual report on Form 10-K and most recent periodic reports on Form 10-Q and Form 8-K. Please refer to Amgen's most recent Forms 10-K, 10-Q and 8-K for additional information on the uncertainties and risk factors related to Amgen's business. Unless otherwise noted, Amgen is providing this information as of Feb. 11, 2009 and expressly disclaims any duty to update information contained in this news release.

No forward-looking statement can be guaranteed and actual results may differ materially from those Amgen projects. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for Amgen to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and Amgen expects similar variability in the future. Amgen develops product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as Amgen may have believed at the time of entering into such relationship. Also, Amgen or others could identify safety, side effects or manufacturing problems with Amgen's products after they are on the market. Amgen's business may be impacted by government investigations, litigation and products liability claims. Amgen depends on third parties for a significant portion of its manufacturing capacity for the supply of certain of its current and future products and limits on supply may constrain sales of certain of its current products and product candidate development.

In addition, sales of Amgen's products are affected by the 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 healthcare 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 Amgen's products. In addition, Amgen competes with other companies with respect to some of its marketed products as well as for the discovery and development of new products. Amgen believes that some of its newer products, product candidates or new indications for existing products, may face competition when and as they are approved and marketed. Amgen's products may compete against products that have lower prices, established reimbursement, superior performance, are easier to administer, or that are otherwise competitive with its products. In addition, while Amgen routinely obtains patents for its products and technology, the protection offered by its patents and patent applications may be challenged, invalidated or circumvented by its competitors and there can be no guarantee of Amgen's ability to obtain or maintain patent protection for its products or product candidates. Amgen cannot guarantee that it will be able to produce commercially successful products or maintain the commercial success of its existing products. Amgen's stock price may be affected by actual or perceived market opportunity, competitive position, and success or failure of its products or product candidates. Further, the discovery of significant problems with a product similar to one of Amgen's products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on Amgen's business and results of operations.

The scientific information discussed in this news release related to Amgen's product candidates is preliminary and investigative. Such product candidates are not approved by the U.S. Food and Drug Administration (FDA), and no conclusions can or should be drawn regarding the safety or effectiveness of the product candidates.
