Amgen Announces Positive Top-Line Results for Denosumab Treatment of Bone Loss in Men With Non-Metastatic Prostate Cancer Undergoing Androgen Deprivation TherapyData From First Pivotal Study in Men Met Primary Endpoint of Increases in Bone Mineral Density and Secondary Endpoint of New Vertebral Fracture Reduction
THOUSAND OAKS, Calif.--(HSMN NewsFeed)--Amgen (NASDAQ:AMGN ) today announced findings from a three-year pivotal Phase 3 placebo-controlled trial evaluating denosumab in the treatment of bone loss in men undergoing androgen deprivation therapy (ADT) for non-metastatic prostate cancer.
In this study of more than 1,400 men, denosumab treatment produced statistically significantly greater increases in bone mineral density (BMD) at the lumbar spine (primary endpoint) and non-vertebral sites compared with placebo at multiple time points. These improvements in BMD were consistent with those seen in other denosumab studies evaluating BMD in women with breast cancer receiving aromatase inhibitor therapy, and in post-menopausal women with low bone mass.
During the 36-month evaluation period, men receiving denosumab experienced less than half the incidence of new vertebral fractures (a secondary endpoint) compared with those receiving placebo, a statistically significant finding. Furthermore, in the denosumab arm there were fewer non-vertebral fractures over the 36-month period.
The incidence and types of adverse events observed in this study were generally similar between the denosumab and placebo groups. The most common adverse events across both treatment arms were arthralgia, back pain, constipation, and pain in extremity. Serious adverse infectious events occurred in approximately 5 percent of men receiving placebo treatment as compared with approximately 6 percent of those receiving denosumab.
“This pivotal study in men with prostate cancer demonstrated once again that denosumab increases BMD consistently at all sites measured. We are also excited by the reduction in vertebral fractures, which permits the conclusion that the increased BMD seen in patients receiving denosumab is associated with improved bone strength,” said Roger Perlmutter, M.D., Ph.D., executive vice president of Research and Development at Amgen. “We are encouraged by the potential benefit this may represent to prostate cancer patients undergoing ADT for whom bone loss and fractures are serious and under-recognized complications of cancer treatment.”
About Denosumab and Amgen’s Research in Bone Biology
Denosumab is the first fully human monoclonal antibody in late stage clinical development that specifically targets RANK Ligand, the essential regulator of osteoclasts (the cells that break down bone). With more than 19,000 patients participating in trials across indications worldwide, the denosumab development program is the largest ever initiated by Amgen. This broad and deep development program demonstrates Amgen’s commitment to researching and delivering pioneering medicines to patients with unmet medical needs. Amgen is studying denosumab in numerous tumor types across the spectrum of cancer induced bone disease. Over 11,000 patients are currently enrolled in denosumab oncology clinical trials testing the drug for bone loss associated with cancer treatment-induced bone loss in breast and prostate cancers, for the prevention of skeletal related events due to the spread of cancer to the bone in Multiple Myeloma and multiple solid tumors, and for its potential to delay bone metastases in prostate cancer. The denosumab oncology program has a specific commitment in prostate cancer, studying more than 4,300 patients to determine the treatment effect of denosumab to treat and prevent bone loss, treat and prevent SREs and delay bone metastases in men with prostate cancer.

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 14, 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 health care cost containment as well as United States (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.
