Amgen Announces Positive Top-Line Results for Denosumab Pivotal Postmenopausal Osteoporosis TrialStudy Met Primary Endpoint of Reducing New Vertebral Fractures and Secondary Endpoints of Reducing Time to First Non-Vertebral and Hip Fractures Adverse Events Similar to Placebo
THOUSAND OAKS, Calif.--(HSMN NewsFeed)--Amgen (NASDAQ: AMGN ) today announced findings from the pivotal fracture trial evaluating its RANK Ligand inhibitor, denosumab, in the treatment of postmenopausal osteoporosis.
In this pivotal, three-year, international, Phase 3 study of approximately 7,800 women with osteoporosis, patients were randomized to receive either denosumab, given by subcutaneous injection once every six months, or placebo injections. For the primary endpoint, treatment with denosumab resulted in a statistically significant reduction in the incidence of new vertebral fractures compared with placebo treatment. In addition, women receiving denosumab experienced a statistically significant reduction in the incidence of new non-vertebral and hip fractures (each secondary endpoints) compared with those receiving placebo.
The incidence and types of both adverse and serious adverse events observed in this study, including serious infections and neoplasms, were similar between the denosumab and placebo groups. The most common adverse events across both treatment arms were arthralgia, back pain, hypertension and nasopharyngitis.
“Fracture is one of the most common health events a postmenopausal woman will suffer. Globally, one in three women over 50 will experience a fracture in her lifetime,” said Dr. Ethel Siris, director of the Toni Stabile Osteoporosis Center at Columbia University Medical Center and immediate past president of the National Osteoporosis Foundation. “I am particularly excited about these findings because they indicate that denosumab may offer an important new option for patients.”
“This long-awaited study demonstrated that denosumab treatment both increased bone mass and reduced the risk of skeletal fractures in women with postmenopausal osteoporosis,” said Roger M. Perlmutter, M.D., Ph.D., executive vice president of Research and Development at Amgen. “We are encouraged by the magnitude and consistency of the treatment effect and pleased with the safety results. At Amgen we are focusing our attention on ensuring that patients around the world will have access to this important therapeutic advance. We hope to have the opportunity to present the complete data set at the upcoming meeting of the American Society of Bone and Mineral Research in September.”
Denosumab is the first fully human monoclonal antibody in late stage clinical development that specifically targets RANK Ligand, an essential regulator of osteoclasts (the cells that break down bone). Denosumab is being investigated for its potential to inhibit all stages of osteoclast activity through a targeted mechanism. Denosumab is being studied in a range of bone loss conditions including postmenopausal osteoporosis, rheumatoid arthritis, and cancer treatment-induced bone loss (in breast cancer and prostate cancer patients), as well as for its potential to delay bone metastases and inhibit and treat bone destruction across many stages of cancer.
Osteoporosis: Impact and Prevalence
Often referred to as the “silent epidemic,” osteoporosis is a global problem that is increasing in significance as the population of the world both increases and ages. The World Health Organization (WHO) has recently identified osteoporosis as a priority health issue along with other major non-communicable diseases.
The economic burden of osteoporosis is comparable to that of other major chronic diseases; for example, in the U.S. the costs associated with osteoporosis-related fractures are equivalent to those of cardiovascular disease and asthmai,ii,iii. It has been reported that osteoporosis results in more hospital bed-days than stroke, myocardial infarction or breast cancer.iv

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 our business. Unless otherwise noted, Amgen is providing this information as of July 25, 2008 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 we project. 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 us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. We develop 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 we may have believed at the time of entering into such relationship. Also, 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 products liability claims. 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, sales of our 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 our products. 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. We believe that some of our newer products, product candidates or new indications for existing products, may face competition when and as they are approved and marketed. Our products may compete against products that have lower prices, established reimbursement, superior performance, are easier to administer, or that are otherwise competitive with our products. In addition, 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 and there can be no guarantee of our ability to obtain or maintain patent protection for our products or product candidates. We cannot guarantee that we will be able to produce commercially successful products or maintain the commercial success of our existing products. Our stock price may be affected by actual or perceived market opportunity, competitive position, and success or failure of our products or product candidates. Further, the discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations.
The scientific information discussed in this news release related to our 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.
